MikeRock Report post Posted July 17, 2020 Do any of your vintage machine users know the composition of 'hard winter wax'? It was melted in thread lubrication pots and the thread was passed through the hot wax, then excess was stripped off by a rubber stripping grommet. The stuff found in old Landis and Union Lockstitch wax pots is hard, black, and brittle with age. Any information on these oldish waxes would be appreciated.

Wizcrafts Report post Posted July 18, 2020 Rockford Leather sells shoe repair supplies, one of which is Sellari's Hard Stitching Wax which is melted in heated pots on stitching machines. It is meant for use on linen thread. Quote Share this post Link to post Share on other sites
