Packard-Merlin 60 camshaft development as billet

grabcad

This effort in SolidWorks sought to avoid multiple NURBS in the description when It is made into a STEP file. The billet was first made to unfinished dimensions with all lobes cut. Then a full version including the 7/8 BSF threaded nose was made. Finally after a successful print of a subscale of the first look was received, the hold thread version was made as in subscale the threaded portion was not printable at my 3DPrint supplier and was submitted for 3DPrint. This second version with all the holes and the rear drive flange which might have made problems 3DPrinted just fine and arrived on the 29th of December, 2017.
