Hi Russel

I just picked up on your thread about the 6125 i am in the same problem, have sent a query to the Sidermeca site. However the motor mod with the vfd is of interest to me.
I am about to make a 72 inch belt grinder but i need my lathe to make some parts, can you provide me with some info to mod as yours. i am in perth WA

many thanks

Need help, suggestion, advice
I can not locate a timing belt for my CQ6125 bench lathe (China made *$@^)
Been to two different belt retailers and they can not identify the belt. Pitch is about 4.8mm, 18mm wide and 2.2mm thick with 118 teeth
The place where I brought the lathe (Hare & Forbes) told me to replace the pulleys with standed pulleys as there do not stock spares #$*@&.

First problem with this is the large timing pulley and the 3 vee pulley cone are all one part
Any one be here before?
Any suggestion

Russell

I have the same lathe. For future problems:

Its a M1.5 - 124 - 15 belt. (M= module , Z= teeth , 15mm)
Grizzly #: P0516944 - TIMING BELT 1.5 X 124 X 15MM
Sieg #: C6-1544 Synchronous Belt / SIEG C6 124T Belt

C4A-210 Timing Belt 1.5*124*15 also from a SIEG lathe

Al thank for the reply
Tried a 5mm pitch belt on the pulley and it start to rides over the teeth after 2-3 teeth.
It is less then 5mm pitch.

Here is photo of large pulley as you see it is one part with vee pulley

Recut the teeth to suit a T5 Belt this is most likely the easiest way to fix it
