I never give up :D
VFD is actually from Taiwan, it cost 2.5 times more then something made in China "koliko para toliko muzike" and for now I think it is worth it (it have sensorless vector control, something like that, what is good as I mange to filter from searching on web). You need to be prepare to pay full taxes, it depends how lucky you are, in which position is moon , stars ...:D , I paid approximately 60$ on numbers that you mentioned.
I read your post about converting your mill to CNC just few second ago , very cool. Hope you will buy Haas VMC :)
Another thing that I read you mentioned, vibrations from stepper motor, this my motors do not have vibrations because they have encoder, it is stepper with encoder, it have big torque and it is not so pricey if you consider what you get , all the benefits.

Hello Marko, The belt used on the spindle encoder is a 250XL037. Here is one I found on Ebay.....

The numbers on the stepper motor belts are, Gates "PowerGrip" 80132 X 3/4. I have tried to find one , but, those numbers come up blank here...I believe them to be MXL belts with 132 teeth. The pitch is 2.03mm. You can find them, but, the widest width I found here in the states is 6.4mm. I did find a place in England that will make the belt...

Hope this helps :)
Hi, thank you Pete, sure it will help, I do not have a clue about belts, now I can start to search where to buy. Spindle encoder belt is in pretty bad shape while other belts are OK as it seams but I want to buy them in case they break.Quote:

Hello Marko, Great job on the spindle !!! These Emco spindles are something else :)
Hi Pete, thxQuote:

Here I made video how I mounted bearings, I guess it will help someone brave enough to change bearings by it self, bearings are pricey, I managed to buy exact same bearings which were mounted on spindle, I had little chat about bearing designation with seller from Switzerland ,what are the particular letters, he told me all what is not B7010E and P4 UL is year of production and factory plant (if someone will wonder ), P4 is super precision and UL is universal mounting (not matched pair).
I made movie for Mike because I saw he is close to work with bearings so might help him too.
Anyway enjoy guys, if someone see that I made something wrong let me know. Only thing is grease, I tried lot of things before I mounted brand new bearing so I did not wanted to use the most expensive grease , but with today knowledge I would buy it because for those 4 bearing is enough small tube of grease, when you know what you are doing.
