I sold that chair on E-bay for $1700. The round base material hadn't arrived yet from the mill.

Here are some progress photos.

I really though I was going to get to the back today, but the seat pan and the lower supports took longer than I though it would. Cutting foam takes awhile too.

Dimensions follow the last photo.











Seat pan width is 50cm
Depth is 59cm (you won't be sitting on all of that, some is for the seat back to rest on)
Forward thigh supports are 14cm long by 17cm wide.
Yoke cutout is 16cm wide
The seat pan narrows to 46cm at the rear using hard angles not curves. Sorry, I don't know the angle. I eyeballed it.

Seat back is 70cm tall
46cm wide at the bottom and narrows to 36.5cm at the top.
The height of the seat back is 33cm before is starts to narrow. I think I narrowed it an inch and a half on both sides. That measurement I couldn't take as the chair sits now.

The seat pan is 10cm tall. It is made from 3" wide plywood sandwiched between two 1/2" layers, one for the seat and one for the bottom.

The lower supports are 17-1/8" long on the top edge and 11-3/4" on the bottom edge. They are each 6" tall. Again, the angle was eyeballed from photos I have of the Weber seat.

Sorry about the mixed dimensions. I work in both metric and imperial units.

If I left out anything please ask.

Electric knives are great for cutting foam, that's if you can sneak it out of the kitchen!

What about real English numbers, American?

It is beginning to look good. Speaking of seat covers. Does anyone know where you can get the green canvas looking cloth they use in military seat cushions?

[Michael Carter]

Get a duffle bag, though that might be a bit thick. It'll last forever though!

I've got some thin sheet plastic I got from work as a throw away. I'm going to laminate the wood for a smooth surface. I'm thinking of using aluminum flashing too, but it's thinner than the plastic and I don't think it will hold up as well.

More work today...

Nick at APHS is sending me a new inertial reel harness for the shoulder straps on Friday.

The detail isn't so great on the thigh supports, but I don't have any close-ups to work from, only shots from several feet away. This took several hours to fabricate from making the brackets and cutting aluminum channel to making sure everything lined up properly

The plastic laminate around the circumference of the seat back frame will fill in the curves at the top of the seat and it will extend about an inch forward of the edge of the seat back. The seat cushion will sort of sit inside a small alcove, if you will. I may fibreglass the corners with matting after it's installed to increase the strength of the corners.

The seat back cushion will me mounted on a separate piece of 1/8" plywood and Velcro'ed to the 1/2" seat back plywood so it can be removed for cleaning.

Nick gave me the dimensions of he inertial reel harness so I do the layout for the slots in the top od the seat. I think I'm going to narrow these a bit down to 3/8" or so.











WOW! What a difference this make and it's not even finished!
