Super rare harness stitching plate with edge guide and screw..in great condition. Needle strike plate or whatever it is called...size 5/6 14 used needles...some have slight surface rust and or wax build up but could be cleaned, sharpened a re-used? Mostly size 6 with a few 5s I think? In my other post I have a fully working Junker & Ruh SD28 with needles for sale.
Vinculus posted a topic in Leather Sewing MachinesA while ago I acquired two Junker & Ruh SD28 outsole stitchers. I first bought one refurbished actual Junker & Ruh from eBay Germany that came with lots of misc. accessories; and then discovered a Pedersen model 308 locally that I also went and got for €200. I wasn't sure what state the Pedersen it was in, but figured I'd use it for spare parts. As it turns out, they are both in great shape and fully operable! The screw that holds the rod the top thread spool sits on was broken on the Pedersen and I couldn't adjust the tension, but after I drilled it out and rethreaded the hole it's all good. Here they are. Now, I have one issue. The Pedersen's max stitch length is considerably shorter than that of the Junker. In the following picture the top row of stitching is the Pedersen and the bottom row is the Junker: Since I have two of these it doesn't really matter that much, but it would be nice to be able to for example have two different thread colors or thread thicknesses on hand without having to fiddle with the top and bottom tension on one single machine every time I want to use a different thread. The Pedersen also makes slightly nicer stitches, so it would be cool to have it be able to match the Junker also in terms of stitch length. Does anyone know what might cause this? Any parts I should inspect for wear? And yes, I have of course tried using the stitch length adjustment screw to no avail, haha. Also, does anyone have a needle plate for a size 7/8 needle they want to trade for one of the size 5/6 plates I have? I run size 7 needles and 1 mm. Tiger thread, so I really don't have much use for a 5/6 plate. Would also be interested in a stitching plate with the raised lip for stitching soles.
Good afternoon, I am adding an SD28 to my toolbox and even though a lot has been written about this and the pedersen machine, I can not find which thread size corresponds with which needle size. the pedersen 308 manual states : use 6 strand twisted linen, waxed on the bobbin, unwaxed on the upper. needle #5 goes with thread #5, #6 with #6 etc. but these notations are from way before I was born and I have no idea which thread diameter goes with which number. Is it as simple as measuring the needle's blade and take the same diameter thread? Thanks in advance, friendly regards vaporlock
