Anderzander Posted March 31, 2015 Share Posted March 31, 2015 I'm fitting a forward facing seat into the rear of my 90 - which is soundproofed with closed cell foam. For the brackets that mount onto the wheel box I was going to cut the foam and let an alloy spacer/spreader plate of (near) the same thickness for the seat to bolt through - and avoid having to compress the foam so much. The floor has a locking plate to fit to it - and I was thinking of the same alloy plate .... But I wondered about a composite material ? Such as whatever they make chopping boards out of. It's light - waterproof - and would be easily drilled and cut - they also seem very robust ?. Any thoughts or suggestions ? Quote Link to comment Share on other sites More sharing options...
Nigelw Posted March 31, 2015 Share Posted March 31, 2015 I've used nylon choping boards for spacers before now, bought a few cheap ones in black from the pound shop and used them for spacer rings for door speakers, easy to cut and drill, and best of all, bought in the right colour(black be ing mine but the mottled grey was a close second ) they don't need painting unlike steel, alloy or wood products. 1 Quote Link to comment Share on other sites More sharing options...
LiftedDisco Posted April 2, 2015 Share Posted April 2, 2015 You need nylon as far as I know... it sets to a rock solid mass and doesn't compress. I will be at Newbury at the end of the month and am sure there is a chap who sells solid discs for spacers - if this helps, I can get you some and stick them in the post???? Alternatively, solid nylon rolling pin and chop it into segments to suit. The other thought that a lot of the Frontera boys use for body lifts (and therefore, again, needs to be resistant against compression) is ice hockey pucks. As hard as a hard thing, cheap as you like and you can drill them as required. They will never rot, never compress... Any good? Quote Link to comment Share on other sites More sharing options...
Anderzander Posted April 2, 2015 Author Share Posted April 2, 2015 All of that's helpful - I'm not sure how I tell Nylon from another plastic type material though? Very kind offer for Newbury thank you - if I haven't sorted anything by then I'd like to come back to you please. Quote Link to comment Share on other sites More sharing options...
Anderzander Posted April 2, 2015 Author Share Posted April 2, 2015 Actually - I've just done a search on eBay and you can buy sheets of nylon in various sizes and quite cheap too. Looks like the answer ! Quote Link to comment Share on other sites More sharing options...
Cynic-al Posted April 2, 2015 Share Posted April 2, 2015 Although not seen as the correct way to do it commercially we usually use this to identify unknown plastics http://www.boedeker.com/burntest.htm Also polyolefins float in water (PE and PP) Quote Link to comment Share on other sites More sharing options...
Daan Posted April 3, 2015 Share Posted April 3, 2015 you want this: http://www.eplastics.com/UHMW_Sheet Daan Quote Link to comment Share on other sites More sharing options...
simonr Posted April 3, 2015 Share Posted April 3, 2015 I agree with Daan, Ultra High Molecular Weight PolyEthylene UHMWPE (pronounced at work as "Umpey Wumpey" ) or even High Density PolyEthylene (HDPE). Si Quote Link to comment Share on other sites More sharing options...
Anderzander Posted April 3, 2015 Author Share Posted April 3, 2015 Thank you both Though I've ordered the nylon block .... I can't see any 10mm umpey wumpey sheets on eBay - but the same seller I bought the nylon sheet from does 10mm HDPE sheets. Quote Link to comment Share on other sites More sharing options...
missingsid Posted April 3, 2015 Share Posted April 3, 2015 Is this worth moving to tech archive as I'm sure it would be usefull? Marc Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted April 3, 2015 Share Posted April 3, 2015 You can make yourself some nice rear X member and bulkhead outrigger protection flaps with a square metre of 3mm hdpe. Quote Link to comment Share on other sites More sharing options...
Anderzander Posted April 6, 2015 Author Share Posted April 6, 2015 Next question please ? What to cut the plastic with ? I first thought of the grinder with a thin disc - but I'm concerned about Heat build up and melting LR expanding the plastic. I also thought about a wood saw - but aI imagine that may take a very long time ... Quote Link to comment Share on other sites More sharing options...
De Ranged Posted April 7, 2015 Share Posted April 7, 2015 with 3mm I just used a pair of tin snips.... worked well gets a bit tough on the hands after a few meters tho lol. If its thicker I'd use a jigsaw with a plastic/wood style bit The grinder cuts it easily enough... on the thicker stuff you do get some melt on the edge of the cut but unless your precision fitting it I wouldn't worry catch for me is when you go to use the grinder for metal again it smells of burning plastic lol Quote Link to comment Share on other sites More sharing options...
