seats

I agree with JW in starting with a ply base. A few other points that we use to make a commercial grade seat.

1. We only use hypalon for the cover. Costs a bit more but will last as long as the tubes !!
2. We use a closed cell foam that we purchase in any size from a company called Sherlock Foams (on net) and supply by carrier.
3. The ply base is good quality 3/4 ply. The foam is bonded to the ply with sikaflex. The foam edges can be trimed for softer corners.
5. The hypalon is fixed taught (heat gently first to allow for warm weather expansion) over the foam and is sikaflexed underneath with galvanised staples holding it inplace until the sika goes off.
6. As JW notes the ply can then be screwed from underneath.

Not the softest seat in the world but does the job for a 1001 bums, takes a pounding and NEVER absorbs water.

Cheers

John

You can get foam from flew sails in Porchester, yo can also get foam from several upholsterers in Southampton. there is a good one in Bitterne, what part of the Uni campus do you attend?

I have a c ouple of sheets of marine grade 3.4 inch ply which are kinda kicking about waiyting for me to do something with so if you let me know your dimensions I'll cut the bases for you ( no charge)

The hypalon cover sounds very sensible to me

I do not have the privilege of knowing the 'ins and outs' of your trouser department but I do know that Richard does not have any problem such as the one you describe!

What can I say! Bigger surface area = more force, I guess.

Guys,

Thank you for the help, this has been very useful. This place in soton sounds good. Stu, I live near the B&Q in Swaythling and study at the highfield campus. This Bitterne place shouldn't be too far away.

JW, thanks for the pictures and advice, thats very helpful.

John, an interesting tip you have raised about using hypalon...sounds like a plan!

Thanks again. Any more tips/info?! Does anyone have any patterns for cutting out the material?

Cheers

Tim

Tim..... I re upholstered my current seat last christmas ok actually i got my mum to do it for me as she is a seamstress, after spending ages sourcing the material we eventually found it to be the cheapest at the local market !!, i'd intended to have new foam cut to shape but when we dismattled it and dried everything out we found that the current foam wasn't in that bad condition.
She made the pattern by dismattling the old seat cover, the new cover was made slightly small so it fitted snuggly and then stappled down over the ply base.
I'd not thought about using hypalon material as a seat cover, though suspect you'd need to glue it rather than stitch it as it wouldn't be waterproof and to stitch you'd need an industrial sewing machine........maybe stitch then tape and glue over the seams inside to create a water proof seal.



Tim
