(In)destructible Husqvarna
In between the fun stuff I promised to refurbish a few machines to give to a refugee reception center. The Husqvarna CB-N and series 8 and 12 straight stitchers are common here, I'd collected 4 freebies/cheap ones to see what I could get from them. Wonderful machines, by the way, will post a thread with a good one later.
I had high hopes for this particular CB-N because it turned really smoothly with the hand wheel, very little friction, just a very slight rasping sound I didn't recognize. Feed moved nicely, even dropped without any force. Quick job, I guessed.
After a couple of hours work on the wiring and cleaning the head - starting on the bobbin area, I finally eyeballed the hook assembly while turning the hand wheel. It didn't move.
Pictures tell the rest of the story. No wonder there was little friction. I prefer to believe that the person who listed the sm as functional in the giveaway section didn't know what he was doing.

Silver solder might be one option. If there's enough room, you might be able to drill and tap it for a screw thru the break as another way of repairing it. I'm not sure that there's enough surface area for glues like epoxy to hold.

100% correct Rodney. The drill through, tap and set screw is the right way to fix this. Then, during assembly, add as thin a layer as possible of JB weld to the seam before applying the set screw. (most folks do not realize that it works better the thinner you can apply it)

Ah, thank you guys. Good advise, and maybe I could get all my thumbs organized to pull it off...
As it is, I'll put it aside for now and work on the other machines. These machines are so common I'll definitely find a spare, and maybe this will be my first complete tear down and rebuild.
