Expanding Foam Seats, any pics?
Has anybody got any pics of homemade expanding foam seats?
If so can they post them so I can have a look.
Cheers!

Its really depends on what your looking for.
I've got a Tiger Cat and as is the Tiger way, you cant bloody fit any "normal" seats (well, without mods), particulary shell type
ones, due to the 'Pigs Ear' sections for the rear suspension
I wanted something comfortable, but not pricey .
The expanding foam seats fit the bill perfectly. Very comfortable over long journeys as perfectly moulded to my backside, easy to make and cost about
a tenner!
The only downside is that they dont look too pretty, but my cars no show queen so not a problem really!!

NS Dev - this is the way i'm going. I should have at home some web sites showing how they are made. Ben Marriott and Martin also have foam
seats. Ben should be at the next Locost Midlands meeting. Fromt what I've seen, covered in black gaffer tape they look ok and are damed comfy
once you've got the hang of making them.
This thread has been covered before - try a search, it should turn some stuff up.
oh, get your foam from a boat builder / GRP suppiler not from a motorsport company its 200% cheaper.

Cat Seats
Bob,
Do you post on the Tiger Owners Club forum? I think someone there had a set of second hand Tiger seats (with the pig ear cutout) for sale, if not post
in the wanted section.

These few answers hit the nail on the head! having had quite a bit of experience with seats (mate runs a leading kit car company) in varius forms, I
know how tricky it is to get one that fits the bill perfectly.
I am NOT going to spend £160 on seats that don't fit but look okish, when I can spend £20 on seats that look a bit dubious but fit perfectly. I
considered buying the £160 shell seats, then foam filling them around me to get the best of both worlds, but I think I will just go for the foam, same
as MikeR et al.
Oh yes, the 2 pack foam from CFS fibreglass supplies is £16 for 5 Kg, and I checked with them and you can apply polyester resin over the foam when it
has cured, so there is no reason that you can't apply a layer of resin and matting, and then paint on a layer of gelcoat "topcoat",
which apparently gives a reasonable finish without having to make a mould.

Can you cover expanding foam seats in anything other than gaffer tape?

I ment more like leather/vinal/cloth etc.
Preferably with a thin layer of foam padding underneath if the seats are too firm. I'm not sure how hard/firm expanding foam goes, but
obviouesly quite hard if you can give it a gel coat.

yes, it will be hard (matting plus gelcoat over the foam, just gel would crack I think) but as I have said on seats before, if the seat fits properly,
you don't really need padding, that's only to fill the gaps on seats that don't fit right!

just to be pedantic........
your clothes will cause ripples, bulges etc..... you will put on and loose weight.
I know you race in a metal seat but over a long jouney i'd expect some amount of flex would be an advantage.

I'm planning on doing this over the weekend. I'll put up some piccies when its done.
So mike, does this mean your going to strip off before you make your seat for perfectly molded finish.

some piccies would be great Dave!
I am a little way away from seats at the mo, just worrying that cos I am short in the leg and the ST chassis is quite long, a foam seat might not get
me close enough to the pedals!

Then mount the pedals nearer the rear of the car (seat). If your using a prebuilt pedal bow this is slightly harder, but still posible.

I have considered it, but it means chopping about an awful lot of nicely powder coated chassis, and a lot of extra complication in several other
areas, which I don't really want!

errr, no!
But I will provide materials and some labour if you go the homemade route!

thinking one more try at the top mount, then i'll convert my top mount pedals to bottom mount ....... if i've already got the pedals why
make new???

that's ok, but you'll find that by the time you have converted them, the only bits you will use are part of the shaft and the bush tubes,
the pedals will be too long for floor mount and the pivots not in the right place to suit the shortened pedal!
Done this one before!
The shafts are useful to save cutting out new profiles from sheet though.

For what it's worth..
On mine I used an inclined plywood seat-back to position the seat squab a bit forward. The back has a wooden spacer block lying on the floor to hold
its inclination angle and it's fixed to the ali back panel with stainless screws.
I needed to get my long body-short legged butt a bit closer forward.
Repositioning the pedals rearwards, away from the bulkhead would be a pain.
I used cut foam, not liquid moulding type, but otherwise it was a pretty similar principle. Steel floor though, and the seat is fixed directly to it
from beneath.
If I had an ali floor I think I'd be tempted to weld some flat steel straps across the chassis on top of the floor and fix to them through the
floor plate.
regards
Dave

Cheers Dave,
I think I will be doing similar to the sloped plywood backrest, I like being fairly reclined and like you said, I am short legged tall bodied too!!
I am still thinking about the floor strips. The only downside is welding with the powdercoating and polyurethane sealer in close proximity!
