Thanks Merilyn , yeah I was going to make it adjustable but run out of time .
Normally I do run it through some sand paper to clean it up David , but in the particular prac where it was used , we were getting unpredictable results and we put it down to inconsistent sanding .....IE some pieces were thinner than others and it was upsetting the results so we just used it as is ( oxidized) and it was more consistent.DavidPeterson wrote: ↑20 Nov 2019, 08:07 Great idea!
