Rib Seats & Backrest

gibbo500 · 14 December 2009, 18:07

Today i have fitted a backrest to the SR4, my question is what is the best material to use to make a pad base? My initial thoughts are marine or exterior ply sealed with resin or similar. Also i am thinking of redoing the seat, is there an alternative to ply or is that the way ahead?

Cheers

13mm marine ply is the way to go. Best to try and scrounge an offcut though, it's £70+ for a full sheet.

Save yourself some money and find any piece of ply, so don't worry about the marine ply. Water some varnish down with white spirit so that it soaks into the wood and build up 3 or 4 layers finishing with neat varnish. The wood will be pretty well protected with the sponge and outer cover. The people that made my seat bases also covered the wood and sponge with plastic before fitting the cover. Use Stainless Staples to fix the outer matererial to the underside of the seat.

I would stick with marine ply but try and scrounge an off cut. When I rebuilt my whole seat last year I went the whole hog and used 3 coats of G4 primer sealer and finished with two of bilge paint. Any and all screw holes and bolt holes were pumped full of sealant as well. I did get a sailmaker to remake the cover and they commented that rarely had they seen as well prepared based.

Just my 2p.

G4 is very good stuff!

And:

There was someone on here who said wrap the seat foam in clingfilm before covering it. I suppose this was if you weren't using pukka closed cell foam??

Won't the cling film give you a sweaty bum?

Hold on a min. we're talking about a Searider here.

Get a piece of ply and cover it in Gaffa tape. Get down to your local pikey site and scrounge a piece of foam from the numerous 3 piece sofas laying around and use the rest of the Gaffa tape and some rubber from a car tire innertube and hey presto!

We all know a guy who used rolled up foam camping mats rather than closed cell.

Hightower · 15 December 2009, 23:14

Downhilldai · 15 December 2009, 23:53

The R&D Dept has taken the product forward.

Now, how many would Sir like? Or are you asking for a friend?

Will the MKII's give the same crotch grab effect as with the MKI's?

Brad,

do you remember where you got /what type of vinyl (type /weight etc) the grey stuff in first pic is (and would you use it again?)

Contemplating doing the retrim myself...been a while since I made that beanbag for me mam in school, but can't be that hard...

I, errr, 'outsource' the fabric finishing, using a reliable local upholsterer, who shapes the foam and covers the plywood bases with a vinyl material which he supplies. Sorry, I don't know the spec, but I can confirm that it's actually black, despite the fibs told by the photo.

Can't say yet whether I'd use it again, as I only collected the seat last weekend and there's a fair bit to do before the new console gets fitted to the RIB.

Pretty unlikely Dan, but if I am, I'll let you know.

Not a bad place to do a day's work.

Good luck - hope it works out for you.
