Members rhinez0r Posted December 13, 2014 Members Report Posted December 13, 2014 Hey folks, I ended up stripping a screw on my Techsew 2750 and I had to remove it with a drill. I took it to a few hardware stores in the area, but nobody seems to carry this (or could even identify it). Could someone help me out? Maybe I could get this online? It's a flathead screw. Here are some pictures: Quote

Members SARK9 Posted December 14, 2014 Members Report Posted December 14, 2014 Its hard to be positive from your pictures, but in general, its less likely to "strip" the threads from a heat treated steel set screw than it is to strip out the tapped aluminium hole it goes in. What I can see of your screw doesn't *appear* to be stripped, unless you mean you have deformed the slot the screwdriver blade fits in. You could easily verify the integrity of your tapped hole by trying the other screw in it and observing whether it draws up correctly. -DC Quote Machines: Juki LU-563, Consew 206-RB5, Singer 20U33, Pfaff 481, Mitsubishi CU-865-22, Consew 29B, Rebadged Juki LU-562, Mitsubishi LS2-180, Seiko SK-6, Juki LG-158-1
Moderator Wizcrafts Posted December 14, 2014 Moderator Report Posted December 14, 2014 (edited) If the threads in the flywheel are stripped, rather than the steel screw, you'll either have to re-tap them oversize and find a new matching set screw, or force some liquid thread repair into the threads, let it harden, and tap them to the original metric size. If that doesn't work, a replacement flywheel can be purchased from Techsew.

Members rhinez0r Posted December 14, 2014 Author Members Report Posted December 14, 2014 I was hoping to get this sorted during the weekend. I took a trip to Home Depot and found a similar thread/size (it's m6) so that should do it for now. I'll contact Techsew and see if they can send me some spares. Thanks for all the help everyone!

Members Gregg From Keystone Sewing Posted December 16, 2014 Members Report Posted December 16, 2014 15/64-28, L=20mm Usually uses two different set screws, one with a ball point that falls onto the V ditch on top arm shaft, the other flat point that falls onto a flat spot on top arm shaft. These are common across the board for many sewing machine handwheels on many makes an models, including Singer 111W155, for an example. As said, get these from your sewing people.
