Out in the shop early,, I bent up the front bumper and tacked it into place. Next was to fab up the seat, I made the seat out of .090 5052 aluminum, Actually got to use my homemade radius brake I built 20 years ago, Still does a fine job, its 60 inches wide,1 1/4 radius, I originally made it for a custom dash project I was doing for a 68 Camaro drag car. With the panel bent up on each side 4", I section off a piece 16" long for the back and used the rest for the seat bottom. With the seat pieces fully welded and fit in place (really comfortable) I made the upper section and cut out the shoulder harness slot. this piece will be Dzus fastened to the car. Now we can move on to the steering rack and tilt columun,) yep Tilt columun...

Very nice! I dig the radius brake...I need to build something like it.

How do track days work? I have heard of them where a Porsche club or something will rent the track for their members, but I didn't realize you could build anything you want and take it to the track. I'm assuming you have to meet some basic safety requirements?

Thanks,, the track days are put on by a couple of clubs that run early camaro's ,mustangs,sports cars.motorcycles,etc. The club rents the track, they do have a tech inspection for safety stuff, they kinda follow SCCA guidelines and police the crazy drivers or unsafe vehicles and safety equipment. Most events are pretty well organized practice sessions for the club racers. Everyone treats each other with a certain level of respect, your not racing, your practicing how to go fast, safely. its fun and well worth the $45 bucks for the day. They run the cars in groups so that the track isn't overcrowded, and the guys can spread out alittle.

$45 thats cheap,at the track I go to Thunderhill in Willows,CA its like $350 for the day.Sometimes its cheaper,and sometimes it more.Like last friday it was only $149 for the day it just depends on what club rents the track.

O by the way cool car,when I get bored with my new track car (67 spitfire with turbo 2.3 ford and T5, 356rwhp and only 1300lbs.)I'm going to build something like this to take to the track.

Nice work so far, looks like you have put some thought into it and are doing it right. I like your sheetmetal roll bender, do you have any more pictures of how it works. It looks like it bends down instead of up and also looks like it rolls the sheet around the radius. Really interesting, maybe you could start a new thread about the bender. Thanx and good work.

I can post some detailed pics of the radius brake, there is a roller that rolls the material around the radius, it helps eliminate scratches in the aluminum.
The brake will handle up to .090 thick aluminum & .0625 mild steel, with a width of 60 inches. The top roller is 2" x .500 wall DOM ,the bottom roll is 2.5"
x .250 wall, its great for making shallow (6" deep ) tanks with radiused corners as the throat of the bender is only 4 3/4" wide on top.

Hey, more pics.... after 2 designs the Tilt column works great..! this was a labor intensive piece, lottsa fun to get it right and offer the strength and simplicity I was looking for. It still needs a few minor details to be a finished piece and I feel it is worthy of some chrome plating just because...LOL

I'd like to thank my best friend Eric for being the Big Guy he is (270lbs) See Eric wants to drive this kart when its done,,, really bad, and without a Tilt column, it wouldn't have happened....! So this Tilts for you bud...

I've read and re-read your thread a couple times. Maybe I'm not paying enough attention. I'm just wondering (right now, probably a lot more questions to bug you with later ). But what are you using for tubing on this?

By the way, definitely loving that build. I used to have a 600rr... nothing like this though!

More pics... Yeah..! its amazing what a few hours with nobody buggin' you can do..LOL

I put the finishing touches to the Tilt column, came up with a clever way to hold the tilt locking bolt from turning when the lock lever is tightened, I took an old 13mm socket , cut off a section, and welded it to the side of the column over the head of the bolt, very clean and does the trick.

Next I made some "poormans weld bungs' by turning down the hex head off several flanged washer nuts ( 1/4 x 28 ) these I welded into the tubes up front to hold the pedal assy cross shaft, the shaft is .625dia .187 wall dom, I cut snap ring grooves to located and space each pedal , plus drilled grease holes for each pedal, the 5/16 - nf bolt is threaded into the end of the shaft and is drilled out hollow then a zerk is threaded into the top to lube the pedal shaft.
Sorry didn't get any pics of the pedal build , I got in the "Fab Zone" and forgot to snap a few..

To make the pedal pads , I hole sawed some curved 2" dia blanks out of a piece of 2 1/2 dia scrap tube, "note I tacked 2 pieces of angle to the tube to hold it in the vice". the pedals were made from .75 x 1.5 rectangle tube, angle cut for shape and lightening holes,then welded to pivot sleeves of .750 x .0625 wall dom, I angle cut and tilted them to the proper position for easy reach by the driver.

Next was the floor board panel , .090 5052 aluminum, bent on the radius brake to fit the shape of the chassis, tril fit , then trimmed to the front of the chassis' shape. I edged it with some poly edging I had in stock for a clean look. I left the protective clear vinyl on untill final assembly.

I really dig the tilt column. That is one idea I'm going to have to file away for later use.

I hope they don't give you any grief about the pedal location when you go to run it. I know some organizations want the pedals behind the front axle centerline.
