Sparky,

Thanks for looking in. If you have had yours that long, you are probably ahead of me with your modifications. Did you do any write - ups?

Next on the list was to fit the motor. The old pulley mounting plate also served as the feed gearbox cover and had to be removed and modified to fit the motor pivot blocks and the arc for the for the motor adjustment. As I mentioned earlier I needed to be creative with the set up to achieve this! First I chained drilled inside the curve then finished it of with a milling cutter to the line. Hylomar Blue was used as a sealant for the blocks and the plate reassembled. New oil replenished the gearbox.

Off of the machine I programmed the VFD, not to difficult, I just followed the manual instructions.

Electrics next.

John Rudd:
Is that the final resting place for the vfd or is it just a temporary location?

David Jupp:
That guard added on the fan end of the motor looks as though it might be rather restrictive to air flow - I'd suggest you keep a careful eye on motor temperature. If the motor has a temperature sensor in the windings, the VFD will almost certainly be capable of making use of it.

dvbydt:
John - yes it is mounted on 4 short lengths of studding, mainly to clear the hinge on the door. There is no fan in this VFD so there has to be space around the heat sink. It is in the end cabinet because it is isolated when the door is opened by a micro switch. The contactor is mounted in the black plastic box on the top left, I had to reduce box height to give clearance for the belts.

David - I don't disagree but swarf might get in and rattle around with the fan without the guard! It will need to be modified if the motor shows signs of overheating - no problems so far.

Thanks for taking an interest.

Ian
