Members Cferna27 Posted July 16, 2019 Author Members Report Posted July 16, 2019 Im talking to my welder friend right now about all of this? it is the quickest and cheapest fix, but can be touchy later on as i'm finding out. I'll update when I can. Thanks again for all the suggestion. Great bunch of folks! C. Quote

Its not difficult to do.... however, other types of welding take much more skill and knowledge... Regarding it flying apart at an inconvenient moment.... Why would it? There is no torque on that part of the fly-wheel... Its the rim and there is no leather drive band... Quote
DonInReno Posted July 22, 2019 Report Posted July 22, 2019 It’s pretty straight forward to braze or silver solder the parts back together if it didn’t bend much before it broke - cast iron comes in many flavors and some bends a little and some doesn’t. Your input shaft may also be bent a little and it’s easy to determine with a basic machinist dial indicator. You may mention to your welder friend that any sewing machine has spent it’s entire life being covered in oil so he’ll need to bake the oil out of the pores before brazing. This will also reveal any cracks that need to be ground out as thin black lines. Some machinists put cast iron in the wood stove overnight to bake it out, but heating it up to a dull red with just about anything is all you’ll need. good luck! Quote

I thought it was in two parts the one fixed on the machine and the other part to the left and low down, not the chips out of the wheel on the machine, maybe i am wrong Quote Mi omputer is ot ood at speeling , it's not me
Members Gunnarsson Posted July 22, 2019 Members Report Posted July 22, 2019 Huge flywheel, I'm assuming this machine is meant for low speed? Wouldn't worry about it. High speed rotation may throw pieces around, at low speed they just tend to fall down - if anything breaks at all, and after a proper repair it shouldn't. Quote
