Hi everyone,new here- my first post.Has anyone succesfully made their own PV spacer?Just trying to find out if alot of you have done it and if other materials other than aluminum has been used.If so what were the results.Also,I dont know if there is enough intrest in it but any thoughts on starting up a Group Buy where say a machine shop is contacted to make a small run of parts.If enough people want one,a bunch could be ordered at the same time and cost per piece would be kept low.The more the merrier!
