Had a update and set of patterns from the pattern maker Dave. They’re very good but not finished, no radii, draft angles or fillets yet. Changes now will be easy to accommodate, but after the radii and fillets are added much less so.
We’re having a good measure this week, returning the patterns once we’re happy for the final finishing. Within a couple of weeks we could have the finished items!
In the meantime, check out this patter maker’s rule. It over reads by 1 in 77, to allow for contraction of the metal on cooling. So the pattern can be measured and the measurements compared with the drawing, without any conversion. Very neat!
Best no leave that lying around, it would cause havock!!
