Just to conclude the pattern making session I thought I would add a couple of posts of the finished flywheel pattern.
The almost 400mm dia rim was too big to turn so I did it on the mill, the "s" shaped curve on the inner edge was cut using co-ordinates from Alibre . This is where a DRO on the Z is handy as often the step is very small and hard to do with handwheel graduations.
The spokes were then built into the rim and a disc of 6mm MRMDF added to the hub to both bring it upto thickness as well as add some strength to the spoke joints. The 2deg draft angle was cut by packing one side of the rotary table, same method for outside of the rim.
After a bit of filler and sanding it was done
All the patterns together

With the possible loss of some of the F360 functions I thought I should get a few bits that I already had drawn out run through their CAM and knock them out.
First up were a couple of simple 2D contouring jobs being the timing bracket and a knob to lock it's position for the Thompson engine, couple of holes also done on the CNC for the bracket.
Then the rocker arm for the same engine from steel roughed out with 3D adaptive and then shaped with "steep & Shallow"
Finally the conrod, a rectangular blank was milled down from some round 2014 and the two holes reamed on the manual mill then these holes were used to hold the blank while the 3D adaptive and Steep & shallow did their thing.
