Tonight’s work was all about ergonomics. More specifically, the best possible location for the E-brake handle.
This is the handle and bracket assembly that sits below the transmission tunnel, with the mounting box I made for it a while back sandwiched in between:
The box I made for it at the time was intended to be flush welded in, but I’ve since changed my mind on that. More on this in a minute.
Because ergonomics play a pretty important role in having everything within reach while strapped into the car, I began by bolting in the driver’s seat, the hydroboost and pedal box, and the steering column.
The hydroboost wasn’t 100% necessary to go in, but it was easy to get out of storage and provided the studs to hang the pedal box.
Speaking of installing the hydroboost, I took the opportunity to blow off and have a look at the engine while I was under there. The big 462 Olds is still all there, just patiently waiting for me to get back to her. It’s been some time since anyone has seen under the hood, me included!
As soon as the seat was in and fastened down, I immediately checked something I’ve been a little concerned about: clearance between the new rear floor kickup, and the back of the seat bottom/track assembly in the rearmost position.
It’s damn close, no question, but it does indeed clear. Thank gawd. If push comes to shove, I can also always shim the back of the seat up slightly between the seat and base, or maybe even section the front of the base to drop the front a little. So there’s options.
Once I had the main components in, I positioned the E-brake handle where it felt most comfortable, and would clear any major components like the driveshaft safety loop under the floor. It turns out, that was about 1 1/2” back from the joint between the transmission and driveshaft tunnels:
This position is well clear of the shifter arm and knob, no dangers of hitting one with the other.
Ok, now onto the E-brake handle box. The box and the surrounding area is going to see some repetitive forces applied to them, so after thinking on it for a bit, I decided flush welding in the box might not be the best idea. Not a lot of strength there, and comes with the risk of tearing the weaker sheetmetal beside a weld-hardened spot.
So with that in mind, tonight I whipped up a new box. Basically the same as the old one, but with one important added feature: flanges.
Instead of welding it in flush all the way around the perimeter, the new box will have flanges that overlap the transmission tunnel and be spot welded on. This is more like what the factory would have done anyways, and guaranteed to be a helluva lot stronger.
Old box next to the template for the new one:
Determine the centerline and location of the hole, then make it so:
After a little Rktpwrd magic, I had the new box created and test fit in the hole. I’m pleased to report that it fits incredibly well, nice and snug with no movement.
Pulled it back out, and sandwiched it back between the handle and lower bracket:
And voilà, test fit in place:
Looks pretty damn good in there if I do say so myself, and another test of the ergonomics revealed that it’s location is absolutely perfect for me. When I drop my hand off the shifter, it naturally falls right to the E-brake handle. It feels completely natural. Mission accomplished.
Now I just have to punch a couple of plug weld holes in the flanges, and burn it in solid. This is going to be SO much stronger than flush welding it in, especially with all the bends in such a small area.
I love small little projects like these, easy to knock out in a night and fun to do to boot.
That’s all for a couple days guys, we’re taking Olds Cool on a weekend road trip to The Street Machine Weekend in Lethbridge tomorrow, and won’t be back until Sunday night. I’ll try and get some decent pictures and maybe some video for all of you. I’ve been before, and it’s almost always guaranteed to be a good time.
