Finally, it's assembled and running.

Now I have to figure out how to install controller on the headstock.

Look at that belt "clearance" at top. Sent from my LG-H872 using Tapatalk

I will have to cut away side wall on a new pulley because it is impossible to install a belt. There is no clearance on the top side of the bore and belt can't pass over the right bearing onto the pulley. Notice a bottom half cutaway on picture but zero on the top of headstock. Am I missing something...

Today I bored one pulley to 50mm and drilled two side holes to secure it onto the spindle shaft. Sent from my LG-H872 using Tapatalk

Waiting for pulleys to arrive tomorrow. In the mean time I reassembled motor and power takeoff shaft. It is running just fine. I ran it from 100RPM up to 3500 and it's purring like a cat. I love it. Overall motor replacement was not difficult at all. Screenshot_2020-02-08-20-02-35.jpg Sent from my L...

I have access to CNC machines and was thinking to make a new pulley but I can't find right cutter for this pulley profile.

New bearings are installed and everything is ready to go but.... I just discovered lengthwise crack on timing belt pulley. It is right at key groove and looks like manufacturing defect. I used bearing puller to disassemble everything and don't think that I caused the fracture. https://uploads.tapata...

Just a quick update. New timing belt arrived and I installed it without any problem. Thanks for a link to belt calculator. Since I had everything taken apart I noticed. Crunching bearing noise that was comming from spindle. Spindle on my machine has two 50x80x16mm bearings and I am looking around to...

Cut 80mm pocket for motor flange on CNC mill. Everything fits like a glove. I tried to upload video of motor running but file is to large for this forum. New belt should be here tomorrow for a real test. JPEG_20200202_195144_2752852588717934061.jpg 20200202_192741.jpg 20200202_154341.jpg Sent from m...
