That is the transformer for the servo power supply.

Sweet. Never had the pleasure of flying in any of the Rans aircraft. Good friend built an RV-7.

I am getting a little further with my PM-940V CNC conversion. I have built a new control system around an Acorn board. So far it seems to be working properly during bench testing. I totally replaced the OEM system. I received part of my Arizona CNC conversion kit today, hopefully the rest will arrive tomorrow and I can start to assemble it. The control enclosure is shown here:

Also attached is the schematic of my control system.

I have not posted anything for awhile but I have been hard at work on the PM-940V CNC conversion. I am not very good at taking progress photos but here are some:

I made a mobile dolly so that I could move the mill if necessary. It is a piece of 1/2" steel with 4" steel wheels and adjustable feet. The next pictures show the stand on the dolly and putting the mill base on the stand. I have an I beam in my shop with a chain hoist on it that make lifting the heavy parts quite easy.

I put the column on then the XY table and finally the head.
