Members Quade Posted December 20, 2022 Members Report Posted December 20, 2022 Quote You can try to tap a new larger thread and insert a screw BUT you only have 1 try. When the threading is a little offset you will not be able to adjust a matching forward and reverse stitch length anymore and the forward and reverse function then IMO is useless. If it was me I would NOT do it. I agree it's a bit risky. Quote threads are 11/32" x 28tpi. threads 20mm long bulb end on the screw. Someone more skilled than me on a lathe could cut you a bolt with this thread pitch. Choices seem to be: 1 - Find the bolt 2 - Make the bolt 3 - Rig something up (tap or timesert). Or else not use this machine. Quote
Members shoepatcher Posted December 21, 2022 Members Report Posted December 21, 2022 You could take a 3/8 bolt and turn it down on a lathe and put the threads in it. A machinist can do it if you cannot. You need it to run the machine. Have a nut made as well. glenn Quote
Members Tingo Posted December 24, 2022 Author Members Report Posted December 24, 2022 Quick progress report. So I decided to bite the bullet and tapped the hole to 3/8 similar thread pitch. Once I timed the machine properly, fingers crossed. I believe I am good Quote
Members Tingo Posted January 12, 2023 Author Members Report Posted January 12, 2023 A quick progress report, I bit the bullet and tapped the hole out and install a screw size that's is readily available. Included are some pictures. I might get a little handle welded on to the nut at a later date. Quote
Members Quade Posted January 13, 2023 Members Report Posted January 13, 2023 Looks good. If I could I'd replace every screw in my machine with a decent metric screw. Quote
Members Tingo Posted January 13, 2023 Author Members Report Posted January 13, 2023 Yep. I will look into doing just that Quote
