Dig you go straight in with the 20mm drill bit?

No no, I started with 9mm then 10, 14 and 18mm using cutting oil emulsion

Hi JasonB,

In the second run, I just drilled a 100mm deep hole (diameter 20mm) in mild steel, so not too much for that lathe model

Dear all,

I have ordered 2 pulleys and replaced the old one. After a couple of hours of work, the pulley got damaged again -apparently I did not put enough tension in the belt. So replaced the pulley again with my second spare, tensioned the belt better (I could give it half a twist without too much force). A few hours of lathe work later... pulley is again damage with all the teeth grinded smooth. Any recommendations on how I should replace the pulley and tension the belt to avoid this? I'd love to bring it to a Machine Mart but I now live outside of UK and it's not an option... Any tips very much appreciated. Ketan from ARCEuro trade has been super helpful already.

Many thanks

Thomas

Hi everyone,

I need to change the timing pulley of my CL300M lathe, the spare part I received from ARC (C3-148 Motor Timing Pulley) has an internal diameter of 8.85mm but the axis of the motor has a diameter of 7.91 mm, so of course the pulley moves around. Are there several models of these lathe, where the axis diameter has been changed? Any help much appreciated! As I don't live in the UK anymore, I can't just bring the lathe to a shop

many thanks!

Thomas

Hello Thomas,

Do you really have a Clarke CL300M, or is it some other make?

If you have a Clarke CL300M, then you have ordered the wrong spare.

A Clarke CL300M is a C2 - brushed motor base model mini-lathe.

A C3 mini-lathe looks different from a C2 / CL300M mini-lathe.

You have ordered and received Spare part C3-148 - which has a nominal bore 9.0mm as specified in the details on this page link

You should have ordered C2-148 - which has a nominal bore 8.0mm as specified in the details on this page link

  • A C2 mini-lathe is the same as a Clarke CL300M, and to the best of my knowledge, made by SIEG.
  • A C2 brushed motor is smaller in frame size than a C3 brushed motor, made by SIEG.

For further clarification, C2 and C3 and CL300M are brushed motor minilathes made by SIEG.

The above models are different from SC2 and SC3 which are brushless motor minilathes made by SIEG.

Minilathes from Axminster, ARC, Clarke, Zoro/Cromwell - Osaki, to the best of my knowledge are made by SIEG.

When buying spares, it is best to be sure about which SIEG machine you... i.e. specifically SIEG C2, C3, SC2, SC3.

Hope above informarion helps.

Ketan at ARC.

Thanks a lot Ketan, I have now ordered the right parts (-should have asked before ordering...). Would you have recommendations for changing the timing pulley? The first time I did not put enough tension on the belt and it ate the new pulley pretty fast. I would have it done at a Machine Mart but I am living outside of UK now, so I need to do it myself.

best

Hi everyone,

Thank you indeed for all the ideas - I now received the correct parts and managed to fix the lathe.

many thanks!

Unfortunately I can't use the lathe, but will try using a shim the pulley - I ordered some copper sheet, 0.5mm thick. Thanks a lot!
