Fat bucket seat coming soon.:)
 

Neither my friend nor I can get our ample proportions into a bucket seat that fits the roadster . Dave from Equinox has kindly given us a seat to stretch so he can mold off it and make some for us , if sucessful which I am sure they will be he will be keeping the mold and they will be available from him.

Already managed to wedge them out approx 50mm and there is still plenty of room in the chassis for more. Just need to brace up the mold now and have a trial sit in it. If all is well we will put the outside return lip back on and get it prepped for molding.

I'll be putting my order in when they are done then, mainly due to having a 46" waist (child bareing hips,puppy fat...).
Having said that I have an MX5 based chassis order on the books for making one 150mm wider but still using the standard track so that arm chairs can be fitted :eek:

About time someone catered for the larger builder.;)

I am on the larger side I squeezed in a set of mev seats from a rocket really comfy and reasonably cheap

Liking the look of these. Do you have a price in mind yet?

As soon as they are done Dave at Equinox will have the mold and he will be making them so give him a shout in a couple of weeks. I will take them out as far as I can because its easier to add a bit of padding if they need some .

My 36 inch chassis doesn't need a larger seat but I am glad someone is catering for the pie eating population among us

The template in the book for ally seat is a good size for the larger chappy.

I thought you had given up on it.

It's been a long couple of weeks

Low sides would be helpful for us big uns.

I've have been using the back seat from a Ford Cougar with the sub frames removed and just wedging the foam seat base and back section in to the chassis, this has got me thinking about making some proper padded seats.
The old mans Locost has a pair of the Westfield type seats which are soft but being bigger I don't fit between the lumber pads, I don't sit in them rather on them.
What I'm looking in to making is a light steel sub frame seat, padded with PU moulded foam pads (non water absorbing foam) covered with leatherette or vinyl, if I can make these for a reasonable price (no not cheap) would there be any interest?

What are peoples thoughts on GRP seats verses the Westfield/Cobra 7 type seats, I've drawn up a rough list of arguments for both.

GRP bucket seats

Pros
100% Water proof
durable
light
can be trimmed as in cut to fit
can have pads added

Cons
fixed angle between base and back
some times suffer from weak captive mounts
very little shock absorbing properties
shoulder harness holes fixed so non adjustable
quality some times brought into question
pads move about or detach tear from glue

Cobra 7 or proper car seat

Pros
soft bolsters which adjust to different people
shock absorbing
light rain wipe dry if leather/vinyl
comfortable on long journeys

Cons
often heavy
too narrow across lumbar for bigger people
foam soaks up water
often expensive
very little choice

I think a couple of weeks has passed now - any progress?

I tried chopping the seat around and stretching/wedging the fiberglass to gain the width but as soon as the wedges were removed it was back where I started within a couple of hours. The trouble is the mold has to be taken from the inside which is where all the wdges are so I think its probably best to get Dave to slice one in half and add the width in the middle, then mold from that. I have been up to my nuts in work so not had a chance to do anymore on it. I will speak to Dave in the week and see what he says.

Thanks for the update Bob, hope it goes well

Could you wedge then add a grp skin to the back of it so it holds shape when you remove the wedges? Then fill, paint and mold.
