Thread: help replacing wapi scales

I made some scales from plexi glass as u can see in the pic for my wapi ,they came out a little ruff .I did not know this stuff was so hard to work with.I have never made scales or pinned a str8 i have the rod and washer can some 1 tell me how far the rod should extend from the washers.Also i was thinking of using guitar pics glued together and cut to size for the wedge will this work.
