Repairing Cracked Bed on Old Sewing Machine


1894 Frister Rossmann hand crank purchased on Ebay from the UK the end of August.  Darn!  Wish there was a happy ending to this story.  The machine was packaged poorly by the seller.


I'm going (to try) to repair the bed crack with JB Weld.   It is my first rodeo with a repair this extensive.  I contacted my sewing machine mentor Skipper.  He is guiding me through the process.  

Skipper has just finished a cracked bed repair on his Frister Rossmann antique hand crank and is also sharing with me the steps for restoring the black surface (japanning).

You can read about his techniques

Here are some of supplies to make the bed crack repair.  I am waiting on the black aniline dye powder.  Also waiting for Jon's wood working clamps, and his extra hands to help me dry-fit and prepared for the JB Weld repair.  

And of course, it gets a little more complicated than first glance . . . 


Lower right hand side--see the metal ruler I placed on the wood base

Detail - just left of the metal ruler is a chunk of cast iron missing.

Trying some Kroil oil to loosen the hand crank bracket upper screw.  Probably hasn't been loosened in 100 years!  Its on there tight.  After 8 hours, I still can't loosen the screw.  I'll try again later--might have to add some hair dryer heat.  I did some light tapping on the screw--can't do much of that because of the cracked bed.


Detail of hand crank bracket screw upper that is locked down tight.  It is an odd angle at best to access the screw slot.  

Can this machine be saved?  I'll try best.  I will share photos later.
