hey guys grab a chair and get up close.u might like this. first off this my rendition of an article by a guy named trek that i saw on marion county speedway.it is very informative and something that you can do!!i,ll do half tonite and finish later.things you,ll need. get some foam blanks from sluggoslots on ebay.the seller slade is a prefered seller next a mandrell from jw,s speed again, top shelf guy.knock out the plug from the blank and mount it on the rim that you,re gonna use.with a nice small pair of scissors trim em down close to the size you want.this is not the finish size so make em big.next chuck,em up on a drill or dremmel and get the sidewalls closer to finish size. use some 220 or so paper you,ll know what works best after 4 or 5 sets you make.o.k. take the jw,s mandrell chuck it and secure it so it,s stable. lay both rough sized foams on mandrell and cranker up. check the pics u see i,ve got a box to catch foam dust.do the box catcher cuz it could get messy.now start to even up the foams ,maybe even try some different paper sizes to get a feel how the foam behaves.you,re gonna need a tube of flowable silicone.so go get some of that stuff.i,m here to tell ya that you,ll make a bunch of crappy sets at first but you will soon be makin silifoam tires that work quite well and you,ll be very proud of youreself cuz u saved a bunch of money and u mad,em you,re self!!.so fellas check the pics out .i,ll post more soon. class dismissed!! for now.
