Need New Rear Seat - '90 PS190

[shepherd]

Anybody know where I can get a rear bench seat for a 1990 ProStar 190?

The upholstery shop opened it up and found all the wood inside rotted. The seat base itself is made of styrofoam with wood strips molded into it to staple the upholstery to. He says he can't glue new wood strips in because the glue would melt the styrofoam(?).

I figured the easiest solution would be to buy another seat if there is an old one out there (unless anybody has some idea of how to attach the wood "staple strips" to the foam). Otherwise, the upholsterer said he could have a wood shop build a new wooden seat base for me, but I'd rather stick with the light styrofoam base if possible.

Any ideas guys?

Thanks.

When I was building my jump seat, I made the contour part of the base out of stacked 3/4" styrofoam board. After melting one stack trying to glue it to the base, I had to come up with something else. So I wrapped the stacked styrofoam in duck tape, then glued it. It worked like a charm.

I wouldn't count on being able to find an OEM replacement too easily.

Did you put any wood strips in your jump seat when you built it to tack down the material? I assume not, but if you did how did you attach them? If you didn't, did you just wrap the material around your base?

Yeah, I knew it would be a long shot to find an OEM base. But I figured if there was one out there, this would be the place to ask.

There are adhesives available that won't melt the foam. A waterproof carpenter's glue would likely work but something like epoxy would not. Check some of the R/C model building sites because foam is often used in their construction. You might search towerhobbies.com to see what they offer as well.

My base is about 97% wood. The only styrofoam I used was to get the countour so that it would curve with the base of the rest of teh observer seat. There is no wood inlayed into the styrofoam basically because I didn't think to do that. I just stacked it and wrapped it.

I suppose if you have wood in there, you can just screw it together. But if you wrap the styrofoam with duck tape, it will be good to go.

I see now. Nice looking job Doug..

Thanks for the suggestion Pilot. I did a quick Google and found that there are adhesives you can use for foam. I'm going to Home Depot to pick some up and will try it out on a section tomorrow. I wonder why the upholsterer never heard of that stuff...

I'd guess because it's not too often that you have styrofoam seat bases. Does good for keepign the weight down though.

Try testing a piece using Gorilla Glue. I wouldn't think that it would attack Styrofoam, and it's water proof!

What about 3M spray adhesives?
