FamilyBiker Posted May 20, 2013 Author Report Share Posted May 20, 2013 (edited) what does the letter represent? http://en.wikipedia.org/wiki/Shore_durometer i think thats helpful,i did read it and cannot reflect it in here lol ithink its different measuring scales to determine the properties edit:wow this ones understandable!

FamilyBiker Posted May 20, 2013 Author Report Share Posted May 20, 2013 (edited) looking at this chart,80 to 93 are the winners for brake pads in general,with 85/maybe 90 beeing on top,as its mixing most of the properties. i.e.sticky like rubber would be,shear resistant like pu,wear resistant like plastics just a thought Edited May 20, 2013 by FamilyBiker Quote Link to comment Share on other sites More sharing options...
Blake Posted May 20, 2013 Report Share Posted May 20, 2013 gunna try find some 90 and make the best smooth rim compound ever. Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted May 20, 2013 Author Report Share Posted May 20, 2013 (edited) WORD! but wouldnt a soft grade be better for non-ground rims??? Edited May 20, 2013 by FamilyBiker Quote Link to comment Share on other sites More sharing options...
Jake. Posted May 20, 2013 Report Share Posted May 20, 2013 WORD! but wouldnt a soft grade be better for non-ground rims??? That's what I thought, the harder the compound the longer it takes to wear down which means it'll be good on a grind. Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted May 20, 2013 Author Report Share Posted May 20, 2013 That's what I thought, the harder the compound the longer it takes to wear down which means it'll be good on a grind. wouldnt say that in general,the pads i run atm(god knows what the compound is,red/brown/violetish),are soft like rubber,grab on a grind like hell and show no signs of wear after 2 sessions. had hardish pads before that barely survived a session,so its not that easy. prototyping isnt avoidable i´m afraid Quote Link to comment Share on other sites More sharing options...
Blake Posted May 20, 2013 Report Share Posted May 20, 2013 hard enough so it doesn't rip out the backings but soft enough so it grips. http://www.ebay.com/itm/POLYURETHANE-URETHANE-SHEET-1-X-6-X-7-1-2-90-Duro-Black-810-/261212305194?pt=LH_DefaultDomain_0&hash=item3cd177772a seems like this makes sense, can the tartybois offer any advice?

FamilyBiker Posted May 20, 2013 Author Report Share Posted May 20, 2013 hard enough so it doesn't rip out the backings but soft enough so it grips. exactly. i think i´going on a little ride now,concentration aimed on how the pads react and how i wish them to. asked the guy i have them from for the durometer/material per mail,hopefully he can give me the info... 1 Quote Link to comment Share on other sites More sharing options...

FamilyBiker Posted May 20, 2013 Author Report Share Posted May 20, 2013 sooo,next time i´ll concentrate less on the pads,they work for sure though. been kissed by my wellgos,kind regards from your local slippy treestump lol 1 Quote Link to comment Share on other sites More sharing options...
Blake Posted May 20, 2013 Report Share Posted May 20, 2013 going to raise the money and buy some soon. Will keep updated, are you going to do the same? Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted May 20, 2013 Author Report Share Posted May 20, 2013 (edited) definitely,once the right compound is found i´m going to save up to 40 euros per annum on pad refills,thats worth some investigation. but maybe we should agree who´s testing wich durometer and stuff,double testing the same would bring no new results imo. i´ll go for 80 if possible,i like the softness of the pads i use right now Edited May 20, 2013 by FamilyBiker Quote Link to comment Share on other sites More sharing options...
Blake Posted May 20, 2013 Report Share Posted May 20, 2013 I was gunna get the black 90 I linked to earlier Sods law i'll have too hard and you'll have too soft haha Quote Link to comment Share on other sites More sharing options...

Luke Rainbird Posted May 21, 2013 Report Share Posted May 21, 2013 If you're going to try it out, consider the 2 part fluid mixtures you can get on eBay too. You'd be able to make a mould that you can then use for instant win once you're found the right mix which'd save a huge amount of time and effort shaping and cutting pads.

FamilyBiker Posted May 21, 2013 Author Report Share Posted May 21, 2013 does that fluid stuff turn into the certain shore hardness pu? bt that pics stolen from otn,unfortunately i havent got any pu yet. building a mold wouldnt be a big problem,we´ve got a cnc company round the corner at work,they could make it for me. if i only knew it works with that 2k stuff,that would be a treat to use Quote Link to comment Share on other sites More sharing options...
dezmtber Posted May 21, 2013 Report Share Posted May 21, 2013 Isn't it the same as moulding fiberglass resin? If it is carbonmods.co.uk sell a mould making kit. Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted May 25, 2013 Author Report Share Posted May 25, 2013 (edited) okay then,i ordered some 80 a resin liquid and 100g of heat supressing filler,now its getting serious! the only thing is i got to build a mould now,didnt think starting off with liquid stuff at first. so far i only experimented with the chocolate compound shown here: the problem was,this stuff tasted so good that i ate it all,before my rim had the chance to... :wink2: edit:sorry,for those who are interested in pad diy,like bing and mrstix,i found out i can vary the durometer by adding filler and changing the resin/hardener ratio(thanks to rob leech for the tip) from 80a - 95a,so one could just get that stuff as a basic to start mixing from,with like pigments and stuff,too then. its the stuff led diodes are moulded together etc. this will be awesome!
