There is one on Ebay right now David, you might be able to ask the owner about the size and thickness of the bar??

Thanks for all the input from everybody! Jimi, I have spotted that one listed on eBay, it has been there on and off for some time. I did contact the seller asking for some dimensions but got no response. I will take some photos tomorrow of the needle plate and feed dog. Somewhat different from the ones you posted. So my machine relies on the thread wrapping around the tension wheel a couple of times (like a windlass) and therefore there is no release of tension on the upper thread when removing material? I did get that by wrapping it around twice but the bonded nylon thread, being a bit slippy, just pulled around the wheel and still didn't create tension. I think if I seriously want to use it and to make it versatile, I might change the v wheel for two discs.

Will send photos soon.

Many thanks

David

Still maybe something to consider tho. I can remember with one  Frobana I had and wanting to use it without wax and with nylon or poly thread, I put in a separate set of tension discs off some old Singer and it worked beautifully. It gave way better control of the tension adjustment in that way. The double tooth feed foot reminds me of the foot for rubber soles as there is also one with a single spike and blade which puts a bit of pre hole for the needle and a slice into the dampened leather to allow the stitching to bury and be hidden.I don't think a lot of these slippery type threads were around when they designed these machines.Regards Brian

Hi to all responders re my 45K68.

Jimi asked for more photos re the Needle plate and feed dog so here they are.

It appears that my machine has been converted from a dedicated Sole stitcher to a more general purpose machine utilising larger feed dogs and needle plate and whatever goes on underneath them. It is fitted with a V Washer type solid tension device which relies on friction from its side felt discs to create tension but I'm not sure how effective that will be with modern threads.  There doesn't appear to be any feature for slackening off the tension when the presser bar is lifted. As RockieAussie suggested the easiest way ahead may be to retro fit a typical thread tensioning device from another machine. This machine was originally fitted into a treadle and I did acquire the treadle flywheel and axle but thats all, no treadle table.  I will probably use it as a lamp stand base or some such device, it is large and heavy!!

I have been given a Parts List for this machine, thanks to members here and am delighted with the response from this enquiry, thank you all very much. I am much more knowledgeable about this machine than I was a few days ago, what a result!!!

Thanks for the pictures David. yes seems like it has been changed to a general 45k21 type now. this would be the common thing to happen when no more parts were available. the 45k21 still has the dogs and needle plates available ( copy´s) and can still be found around 2nd hand. there were surely more of the common type machines sold. i could be wrong but it dosn´t seem like there is much felt there? another thing that can happen is the disks end up wearing on the flat spot and end up spinning also. if this happens then there is no friction. if your feed dog is working fine then great, you might find a general type dog from the 45k89 might work good also as they were flat and not curved. flat being for their array of flat topped plates they had. what is the number on your foot david??   90751?  94751?  91751? so were you thinking of sewing soles on this or just general leather stuff??

Yes rocky, it does look similar to the frobana setup ? teeth for the rubber and the knife for the leather. the 45k71 had the two rows of slanted teeth and a small knife in a channel in the middle of the plate. i suppose it must have lifted with the foot each time and probably that is why it had two rows of teeth, to pull it through the leather and make the channel??
