I only just built the dummy. I know now that I should have done that FIRST and if I had, then I would make ALL the parts in pep FIRST, fit them ALL to the dummy, MODIFYy their shape, size and fit so they fit the DUMMY (sans-myself) and also fit TOGETHER...
THEN - once happy with the fit of everything and ONLY THEN, would I start the hardening process......
There's always next time I guess.
I've come this far with a bucket load of mistakes, so I suppose it's a whole lot of learning trying to correct what I have so far and make it work.
