    It's not much. Just wanted to show you seat solution. I wanted a seat that would fold flat and tilt forward to access the space under the seat. Bought a 1999 3rd row seat from a friend. For me it worked almost flawlessly. Only real issue is because the pedestal is low and the tunnel high the seat hits the tunnel at about 45°. I wanted the pedestal to have a nice curve to it. While I have a hood tubing bender I dont have any square dies do I used the relief cut technique. Worked well IMO. It bolts to the frame with four bolts through the pedestal at the perimeter of the frame and two through the crossmember. Made from 1" square tubing left over from a previous project. The upper frame attaches to the seat via pins that fit in the hooks and is bolted to the pedestal. 20191209_232736.jpg 20191209_232731.jpg 20191209_232726.jpg 20191209_225112.jpg 20191209_225139.jpg 20191209_225108.jpg 20191209_224817.jpg 20191209_224809.jpg 20191209_212705.jpg 20191209_210442.jpg 20191209_210213.jpg 20191209_210156.jpg 20191209_205511.jpg 20191210_202138.jpg 20191210_202142.jpg 20191210_202150.jpg 20191210_202211.jpg 20191212_210553.jpg 20191212_211224.jpg 20191229_164900.jpg 20191229_164927.jpg 20191229_165014.jpg 20191208_200000.jpg The seat will eventually be reupholstered in a traditional/custom style.

    Wow, above and beyond on that seat base. I want to put a similar seat in the back of my 31 Vic just to be able to fold it down and have a spot for luggage for road trips as the car will seldom have back seat passengers.

    I generally bend tube with a tube bender. But I have some bends that I need to make that are sizes I don't have dies for, so I'm going to be bending the tube like you've done there, cuttings slots in it.

    Mind if I pick your brain with a question?

    Did you do any rough calculations to determine how many slices to make and how far apart to make them? Or did you just wing it, make a few cuts then make a few more until it was the right size?

    damn if I recall where I saw it but there is a formula based on the kerf width and the tube size that works well and can get you bends in both planes... YouTube might have been where I saw it.

    My goal is mild late 50's style custom. I bought it with the suicide doors already done . I wanted to undo it but couldn't find good stock hinges plus it would be a huge amount of work to undo the way it was done. The tilt is because I'm 6'4" and thought I'd need the clearance. Once all is done and seating confirmed if i don't need the tilt I'll remove it for straight old time column.

    I drew out the curve I wanted and measured the circumference. I marked off start and stop and cut every inch. Wasn't enough so I cut each section in half till I got what I wanted. Did make a couple cuts outside the lines as a fine tune.

    Great job, I want to make my right bucket seat tilt forward to gain access to the rear of my sedan. As far as a tilt column, I wish I'd put one in my A sedan, it'd helped a lot getting in and out.

    Thanks :)
     
  18. Does it latch down somewhere on the back side?, you don't want to hit the brakes hard or get rear ended and have the whole seat tilt forward. I like the idea of the double access, both behind the seat and under it.

    Yes it retains the rear latches so it stays down. The seat back wont fold unless the release lever is pushed. It can also be easily lifted out of the car. I'm going to make a folding stand so I can use it as a chair at shows.
