Hi Rebekah
This is my first post so bear with me if it all goes wrong
I fitted a belt drive kit earlier this year and was very pleased with both the kit and the resulting performance.
The kit was from Turkey and is available on e-bay. Search for SIEG x2 mini mill belt drive conversion
I have added (hopefully) a couple of photos on the album.
Fitted at the same time was a gas strut to replace the torsion spring and this works a treat. The strut was ref GS6-15-260-300 with a 10mm Ball stud from SGS Engineering UK – and was set for 40Kg if I remember correctly. It was a little overlength so I fitted an angle bracket to lift the top fixing point up a little as per the photos. I also fitted the longer rack from LMS to take advantage of all the extra travel.
Also fitted was a set of Angel Eyes LED's to provide a good light onto the work surface and the driver for these was attached to the rear of the control box.
Hope this is of interest
Stuart
