dikman Report post Posted November 16, 2019 I was wondering if someone with one of these could do me a favour please? I would like to know the distance from the tabletop to the centre of the main (pulley) shaft and the diameter of the pulley itself (not the handwheel part), also, the distance centre to centre of the four mounting bolts.

(8"apart front to back) (6+1/2"between at front and same at back) to clarify the 2 bolts closest to operator at the front are 6+1/2" apart. Quote Share this post Link to post Share on other sites
dikman Report post Posted November 16, 2019 Excellent! Thanks Brian. I intend to replace my 335 with this machine, I've swapped the motor for a 750w that I used on another machine and fitted a speed reducer (3:1). These measurements will enable me to make sure that the belt will clear the slot and give me an idea if any of my existing belts will fit. Quote Share this post Link to post Share on other sites

I look forward to seeing the progress pics as you go and hope to hear some good news on the machine as well of course. Quote Share this post Link to post Share on other sites
dikman Report post Posted November 18, 2019 Based on those measurements there shouldn't be too many issues fitting it. I have an assortment of pulleys (45 mm, 65mm, 75, 120 and 140) that I can use on the reducer shaft to the head so I can fine-tune the final drive ratio. It's amazing how many pulleys I've accumulated since getting into this sewing machine thing! I've also just fitted a steel channel underneath to reinforce the table against the extra weight. Still waiting for the shipping quote, I just hope the Chinese are quicker at actual shipping than working out a quote!!!! Quote Share this post Link to post Share on other sites
