the passenger side SFC gusset tube.

Moving onto the door bars, an interesting part of the project no doubt, so far has been a very tough part to engineer, as i absolutely must keep the door handles, arm rest, stock seat, and mount the bar in a position that i can actually get into the car.

looks good, definately making some progress.
i know you've done your research on this, but there is one thing i noticed however. of course you can tell sitting there better than i can by looking at pictures, but if your door bars are at about the same point on the seat as it would be on mine (same seats), those would hit me way low, like at my elbow. and as i'm sure you know, they need to be at a midpoint between your shoulder and elbow. if so, those wouldn't fly at that height in my car with a guy my height (not tall, about 5'10), with most of the tough techs around here.
my buddy had door bars that hit closer to his elbows, to make it easier to get in/out and he was messed with everytime we went to the track at mission, BC, and occasionally locally as well. he got around it by sitting way low in his seat, but we both learned it was better to just make it exact, instead of dealing with the BS.
just pointing it out, something i noticed in the pics.

Looking good! Are those Detroit Speed Equip. frame connectors?

For padding, I took a section of tubing and a section of foam pipe insulation to my upholsterer and he made me two lengths, 4 foot I measured, black vinyl hook-and-latch covers with 6-8 inches of loose material on the ends. I would open up the covering, latch it together for the length, then tuck in the ends of the longer materisl between the foam and tubing.

I suppose one could have the ends sewn giving the appearance of a seam rather than tuck in the ends. I used 2 inch diameter black pipe insulation. Comes in 6 foot length from your local HVAC supplier. Insulation has to be cut to match circumference of tubing 2" vs. 1 5/8." Cuts with scissors easy. Single action tin snips work very well.

thanks for the compliments!
for me it passes through the middle of my shoulder and elbow. I'm just under 6'0. Maybe its the angle of the photo, but it passes through the right spot.

Even as is its extremely tough to get into the seat with my stock 16" diameter wheel. I might buy a different steering wheel and a quick release.

I've been looking at these:

my elbow is level with the bottom of the arm rest, and my shoulders with the portion of the seat thats where the sewn in section is.

everett, they're CE subframe connectors that i modified to fallow the contour of my floor pan.

the padding sounds nice, i'm up in the air on the padding, i might buy SFI stuff.

Brian,
Why all the cross braces on the main hoop? Never seen that on any car, i think i may have seen the one diagonal bar on a road race car but never before on a Drag car. Also be careful i`ll check again but that side bar bight have to be between the elbow and shoulder when your hands are on the wheel. Looks real good other than that. How do you plan on painting it? Any performance mods over the winter also?

The quick release really makes getting into and out of the car a lot easier. I used the exact same one you posted the picture of. They work real well. No slop like some of the pin type quick releases.

I know some states back there require a "safety" inspection. With the quick release you will lose your horn button. I don't know what you state rules are, just thought I would point that out. If they allow you to mount a horn button anywhere then it's not an issue.

Drag Fabricator
Feb 9th, 05, 01:07 PM
cool, good to hear they are a nice peice. Might do that some time into the season, as i need slicks at the moment.

i like the big bus driver steering wheel, it will find a new home in the attic though as its pretty tight getting into the car.

Scott, checked it with my hands on the wheel in my "racing" possition. I know it looks low, but it works out for me.
I'm sure Duke will have something to say, but the guys at Etown wont.

The diagonal brace is an idea i found checking out Alf Wiebe's work, so i'll give it a try. The SFC gussets are in there by the advice of larry poppas. He mentioned to me that he originally had only a roll bar, then he had Andy put the gussets in as well and it was an improvement equal to the bar (in the rigidity of the car)

That seat has no side bolsters for protection, if you hit something sliding sideways or get T-boned, it looks like you will be hitting that door bar. Not to mention needing a head rest. I'd get a better seat.

Brian, I'm not trying to be a jerk in any way, just curious, why build a stocker with a non-legal engine? Just like the look or?

Drag Fabricator
Feb 10th, 05, 07:47 PM
There's a multitude of reasons.
first, and foremost, a stock eliminator ride is the best type of car to tailor a street/strip car after.
Second, if i ever have the money to race Stock i have a car already prepped for the job, and only need to put a stock legal engine in it.
Stockers hold alot of value, especially those that work well.

and it really only takes a few considerations to keep the car stock eliminator legal, with exception to the engine of course.

Nothing cooler (in my opinion) then small tire, stock suspension, full interior, stock eliminator cars.

fallow the buildup over the next season, and so on, and you'll see the evolution of a street/strip car that when i'm done will really "Work".

Feb 11th, 05, 01:43 AM
No questions from me, I love a Stock/Super Stock car. It just takes money, patience, and a lot of thinking.

A Stocker is the way to go. Get the shipping weight, horsepower factor, and now you're classed for a specific ET. Read National Dragster on who has bettered the class and wonder how he/she did it.

Read & reread the rulebook between the lines for a better favor to your advantage, to improve your time.

Nah Brian, im with you all the way on it. I think about the coolest thing in the world is a Full interior street car that goes like hell N/A and is driven everywhere. I have a little Grant steering wheel and it makes it alot easier to get in and out of the car. But im 6'2" 250 or so too.

Feb 11th, 05, 12:13 PM
cool! :D

maybe the steering wheel alone with solve the problem. I've spoken to the engineer who developed the quick release from grant, and he gave me a warning that it was un-streetable, and designed to be replaced every few seasons.

Royce, any comments about the durability of the peice. And does it eliminate the turning signals?

Novaguy73
Feb 11th, 05, 01:22 PM
Brian....dont spend the $$$ on the quick release either. I got my grant wheel and the adapter at autozone. I believe its the black GT model and everything was 60 bucks total. If you dont have power steering its not a problem turning at a dead stop either, at least not for me...in fact i prefer not to have power steering in my Nova!!

Feb 11th, 05, 07:01 PM
Brian,
I used thet Grant quick release for over 6 years, it worked the same the day I sold the car as the day I bought it. I took my wheel off everytime I parked the car in public and took the wheel with me. I have never heard of any issue with them and I plan to use one again in my current car. My turn signals worked fine (self cancelling worked fine too).

Maybe they have a new design now or something, I don't know.

I have no complaints, it was very solid and had no slop. I am not sure what could "wear out" in the unit.

Drag Fabricator
Feb 11th, 05, 07:25 PM
Sounds good, i think the "engineer" may have been BSing me, as i mentioned it was a street/strip car, and he was very against me using this peice on the street.

Now that i think about it, i get in and out of the car more times in a race day then i do the entire week fallowing, even if i were to drive it daily (i dont anymore).

Brian,
dont take any of my comments the wrong way, i know in a way they could be. but just tryin to help ya out.

I was looking at the way your shoulder belts are mounted and that tab isnt right. I needs to be in a straight pull design, the way you have it is technecally not, it could bend the tab up. The best way would be to drill a hole in the bar and mount them with a straight bolt through the bar, all you have to do is drill the hole bigger and weld in a small piece inside it like a filler, dont know if you know what i mean.

Drag Fabricator
Feb 14th, 05, 02:06 PM
Scott,
from the picture its sort of an optical illusion, as the tab has a bend in it, but its fit 90 degrees to the bar.

I put the bend in it so that its parallel with the "pull" force, as it goes over the top of the seat back.

Ed's seat belt tab is the same way.

The floor tab is done as illustrated in the instructions for the belts.

I like your idea though, had i not already done this i would have considered it.

What could be done, by those concerned about it (if someone is building something similar) would be triangulation gusset plates on the sides of the tab.

Silver69Camaro
Feb 14th, 05, 02:09 PM
Hmm...I see that too. I guess it would be best to try and load that tab under one axis (tensile) instead of some combined loading. BUT, you could add some sort of gusset there to fix that right up...assuming it's a problem, and it may not be.

You know, if you think about it, that tab bending can lengthen the amount of time your body takes to come to a rest during an accident. If you can design the system to bend, but not fail, during a crash that could be adventageous. Ugh, I'm thinking too much.

That's kinda what I did -- it was pretty easy too. I just welded a grade 8 7/16" nut to the top of the bar though and tapped threads into the top of the bar (below the nut) rather than going all the way through. No tabs or gussets on mine.

I'm not saying anyone has done it wrong . . .

Feb 14th, 05, 03:02 PM
Brian, not as quick or easy but you might consider the Grant steering wheel adapter that lets you take off the wheel for security. You have to use a key to take off the wheel. It doesn't take long. You can keep your horn and everything. I have it for security reasons, there is a red steel cap that goes over the gears so no one can mess with it. THey are about $100 and are supposed to last a long time.

camaroman7d
Feb 14th, 05, 04:05 PM
They make a "sleeve" for mounting seat belts to the roll bar/cage. That is what I used on my last bar, you drill all the way through the bar and weld the sleeve on both sides (top and bottom). It is threaded and you bolt your belts directly into it. Just thought I would mention it since the topic came up.

Drag Fabricator
Feb 14th, 05, 05:32 PM
Cody, i took a look at it, however after tacking up the bar its really not bad getting in and out of the car. I think a smaller wheel and a shallower wheel dish would free up enough room that i could get in and out easy.

thanks for the idea though.

Moving onto the head rest, i've began that portion of the project by completely dissambling a stock 69' Camaro headrest (donated by a friend).
I then sheared the attachment bar off the bottom of it.
Formed a steel plate for the rear section of it, welded it on, and then welded two 5/16" studs to the plate.

http://hobbystage.net/camaro/camaroracer/1108437154-005537.jpg

Next i'll have the headrest portion re-appolstered, and in the mean time i will build a round tube section for the roll bar, and a mounting tab.

overall it will be removable, and very slightly adjustable (up and down).

As Brian stated: My main concern is my safety, but I've done no testing. Couldn't have said it better myself. You want the one test to be the one saving your butt!

Gussetting the corners of the bar will definately strengthen the bar as a whole. You've transferred the vector from the corner to the bar(s) themselves.

Looks nice Brian.

Just a quick idea. I know a fellow here locally who had a factory low back seat and had to have a headrest made up. His design was pretty trick in that the headrest was bolted in, not welded to the main hoop or seat cross bar. He had his mounted where it was clamped in place using the band straps that they use to bolt engine plate mounts in a dragster. The clamps you loosen which allow you to slide the engine/trans forward and back on the frame rails. The clamps went around a piece of curved steel which followed the contour of the roll bar tubing. The head rest was then welded to this curved metal piece which was then clamped to the roll bar...hope that made sense. The clamps not only allowed the headrest to be removed, but also allowed it to be adjusted to fit the driver easier. Once a headrest is welded in, your kinda stuck with the final position.

His car is a 67/68 Camaro which also kept the back seat. The removable/adjustable headrest design also made it easier to get into the back seat, not to mention allowing more room to squeeze the back seat itself through the opening.

Just a neat idea worth considering working into your roll bar design.

Drag Fabricator

Nice job! Its good to see you welded in segmented arcs about the circumference of the tubing. You don't want to pull in the tubing by welding a continuous bead about the circumference.

4130 does weld nice. Good penetration on the welds as shown by the length of discolor.

You could take some scrap metal, make joint, suspend it upside down and practice welding. How do you think your father learned?

I'm also planning on going with a gen III all aluminum small block, backed by a 5 or 6 speed trans. Of course, we'll have to see what the finances allow... if I can swing it I may try to hang a couple of turbos on the engine while I'm at it! :D

the tabs are 1/8" 4130, and the mount to the floor is 1/8" thick mild.

Drag Fabricator,
Man, I have to hand it to you. That is one VERY nice cage you made.
Seeing yours, made me want to re-do mine.
It is similar but not quite as nice as yours.

Looks like that seat is gonna be real fun to get back in. You gonna be at E-Town next weekend? Heard a rummor that they havent finished their starting line yet? Hopefully we will somehow be able to race next weekend, weather it be island, e-town, or atco, Was talking to Bob Bucler and he went down to MIR yesterday to test. Cant wait to get in the car and smell that smoky burn out again.....

How much do ya think the bar will slow ya down? 12.0`s?

Drag Fabricator
Feb 28th, 05, 09:53 AM
i went 11.60s last season, the bar only weighs 57lbs total so far, and will probably be 62-63lbs total when finished, my perspective is that in total the car will be quicker as it will work much better!

plus i took 20lbs of the real heavy padding out from under the carpet, so, total i'm looking at 45lbs more weight.

Next weeks job is to finish another driveshaft loop i've been working on, and overall i expect that to be a little lighter then last seasons (which wasnt spec)

the rear seat isnt bad to get in an out, but its a two person job with all the tube in the way.

i hear ya! I cant wait to get racing again as well, as long as its not rained out or snowed out i will be racing the first points day on the 13th

i'll be done with the bar soon, the headrest will be done soon, and the interior will be going back together soon.

Tires are on their way shortly as well.

What did you ever end up with, i asked melisa last week after i got your call, and she said that the QTP`s were much more consistant but forgot how much in et, sent ya an email but wasnt sure if it went through as i have been haveing problems with it

I will also be at E-town ro the first week of points, i`ll be running Heavy at E-town and Street at Island

Drag Fabricator
Feb 28th, 05, 05:39 PM
didnt get the email, thanks for checking though. I went with the QTP's since you're using them successfully.

good to hear you'll be racing at etown, because i dont think i will be making too many island trips this season. Since i'll be legal in street, i'll stick to street points at etown, and probably a few races at atco.

I'm going to build a mechanical throttle stop this weekend or next week.

Awsome, Make sure to take some pictures of that as i might be using one this year also. If it does what most say it will, were looking at the 12 inch 1500 stall convertor and a cam swap to keep in in the 12.0`s but hopefully we`ll find out this weekend.

Welding the connectors in tonight, i put 2 bolts in each because i couldnt fit 4 but they sure make the car solid, when i jack the front up the back jacks just as high as the front, where as before it would have to come up like a foot and a half before the back came up with it

Drag Fabricator
Mar 1st, 05, 06:05 PM
exactly, just image how stiff a roll bar makes it after that, especially one that ties into the SFC's!!

Hehe, i go out to the garage and push on the main hoop just to watch the nose of the car rise with the force put on the main hoop.

good luck with the job, and welding them in should stiffen it up quite a bit more!

that car should be flying this season, for the time being, it might be worth while putting a mechanical throttle stop on it.

here's yesterdays progress, after i finished this floor cap/SFC guesset floor plate my dad helped out with some of the welding and we accomplished quite a bit.

Lindie 300amp, its older then me :D With a Big HW-18 Torch on it, that we'll be replacing to finishing off the rear bar/main hoop joints near the headliner.

I agree. Now, I know what he's gonna do for retirement...........Need to be certified!

Try some stainless steel. Then you can build exhaust systems for those high-end cars others drive and want more power. They buy a Porsche, then add a turbocharger to it. The exhaust kits are non-existent, must be custom made.

i definetly love working with stainless, my exhaust is stainless and welding that stuff is fun! I'd like to get involved with high end custom fabrication.

thanks for the compliments Everett and Rick!

Brian what do you plan on useing to paint it? We used spray can for my dads but its a pain to not get it all over everything and hard to do a good job, i was thinking maybe air brushing one, have heard of it being done and that way you can use good enamel paint.

I use Krylon Semi-gloss black, it always comes out nice.

I find it easy to use, and i like the semi-gloss since it Matches the overall theme of the car.

DragRacer
Mar 3rd, 05, 04:45 PM
Nice work Brian.

I usually use POR15 chassis black and brush it on. It flows out well and doesn't show brush marks and is very durable. It doesn't scratch off like poof can stuff does. Especially on door bars that you are crawling over a lot. I'll try to remember to take some pictures this weekend.

A start to the head rest mount design
http://hobbystage.net/camaro/camaroracer/1110062481-005884.jpg

Seat Belt tabs, i wanted to use these becuase the nylock nuts and grade 8 bolts let the blet swivel on the mount (just snug) rather then being bolted solid.
http://hobbystage.net/camaro/camaroracer/1110062387-005883.jpg

this sides Done completely with exception to the headrest and finishing up the weld on the top of the main hoop to rear bar, most of its done but we're waiting on another torch to finish it up.

What ever you use dont make it the industrial gloss crap....i just painted my bar and had to sand it all back down because it wouldnt coat right, and there were tons of runs.....satin/ semi gloss is where its at. I just recoated with that and it went flawlessly.

Mar 6th, 05, 01:34 PM
all the paint so far is semi-gloss, looks nice i think.
You're right, spray-can gloss paint is tough to get perfect.
