New/Used Caterham Seat bottom wanted!

[boss351]

If you have upgraded seats or replaced worn ones I am looking for a current spec cloth (or leather I guess) seat bottom (the plastic+cushion part), I want a spare that I can take the stuffing out of for the track to get me a little lower down.

 

Thanks in advance!

Adam, I don't have a spare seat bottom for you, but just this afternoon I made a Foam bead/epoxy seat to get me lower in the car as well.

 

I used foam beads for stuffing bean bags, a large "space saver bag" The kind you see on TV ads with a one way valve for attaching a vacuum. And a two part epoxy.

 

Worked pretty well for an hour's worth of work and a few bucks, $15 for the foam beads, $12 for 2 bags,$24 for a quart of the epoxy and hardener.

 

It is curing overnight and then I will cover it with some nomex cloth if this first attempt is acceptable.

Interesting stuff, pics would help understand the whole thing if you could!

Adam, sorry, but for some reason it won't let me upload the pictures.

 

The process was to fill the bag with the foam beads, to a level that fills the space you are trying to fill. Test fit it to get it spread out just right.

 

Mix the epoxy and pour it into the bag, kneeding the beads to thoroughly coat them. I used about a pint of the epoxy for the seat bottom.

 

Again put the bag in the car and spread the beads out to fill the space and then sit in it to form the seat. Attach the vacuum to the one way valve and turn on the vacuum. Beads will squeeze together as the air is sucked out.

 

Wait for it to cure. Before you start, put your favorite beverage, your phone, a book and some earplugs within easy reach. Also be able to reach the vacuum to turn it on and off.

 

Took about 40-60 minutes for my epoxy to harden up. Wear long pants, because as the epoxy cures it heats up. I wore shorts and almost had to bail as it got pretty hot.

 

I'll keep trying to post the pics.

Check out this article on making your own seat bottom. The plastic bit is available from Oxted Trimming http://www.oxtedtrimming.co.uk/caterhamcars.php

What Tom is suggesting is essentially a bead seat. You can buy kits here:

I'm going to order the seat bottom plastic and fab something up at home, looks like a doable task.

 

Thanks for all the good info here!

Two-part boat foam from any race supplier (Pegasus for example) and a garbage bag...

 

... instant custom seat of decent safety level for track days.
