Members Constabulary Posted December 8, 2022 Author Members Report Posted December 8, 2022 (edited) This machine is a bit different to what I have read in the Class 17 manual (of a later version I guess) so far . At least in terms of how to insert the needle correctly / timing. Usually you shove the needle all the way up in the needle holder tighten the needle holder screw and done. This machine is different. When I took it apart I noticed a very clear mark on the needle bar (very unusual for a patcher). Now that it is almost reassembled again I had to figure how to time the machine. It has an eccentric on the gear box (see earlier post) but it indeed ist not for timing it is for compensating wear on the racks and pinion and that is a great feature! I the hell was not able to figure the timing cause I shoved the needle all the way up (of course). I assumed you can advance or retard the shuttle driver pinion by 1 tooth or so.... but no - did not work. Then yesterday night I went trough my manual collection and hell I found an original manual (German Language) for this machine . Did not even know that I have one and since when - really no clue. Now it is clear what the mark on the needle bar is for. So, you have to bring the needle bar in a position that the mark is leveled with the surface of the top side of the head. Then insert the needle in the needle holder until the needle eye is leveled with the surface of the needle plate. And then the machine is timed right. Unusual but not a bad idea. But you have to know that cause all other patcher machines I ever had (yet) were different to this. Will post more pictures later.

Members Handstitched Posted December 10, 2022 Members Report Posted December 10, 2022 OMG !! I wouldn't have the confidence to do what you have done , just looks great I've worked on old tractors, old landrovers and an old triumph and made them go again,, but not old sewing machines. I think I would have trouble re-setting the timing, but I will be paying attention on here on how you do it. I've always been fascinated by peeps on here doing full restores on old machines. Still reckon the deer emblem will look good in gold against the black, but thats just me, ... or is it ??

Members Constabulary Posted December 12, 2022 Author Members Report Posted December 12, 2022 (edited) Broke the hook but I think I have a replacement, however it may work with out the tab too. Will check... I split a screw while turning the screw driver - no idea how this happened But I´m almost done with the head but still needs some work and maybe some adjustment. Added new longer thread spool pins. I forgot to "electrolyse" the hand wheel... so that's next. I just put it on for testing.

Members shoepatcher Posted December 12, 2022 Members Report Posted December 12, 2022 (edited) Damn. That looks nice C!!!!! Never seen a screw split like that. You wire wheeling the parts after they come out of the electrolysis tank? glenn Edited December 12, 2022 by shoepatcher Quote

MikeRock Posted December 13, 2022 Report Posted December 13, 2022 That screw body looks pretty ductile. I wonder if it can be brazed? Flux it with borax, then squeeze back in shape, then a tiny bit of brazing rod applied..... worth a try. God bless Quote
Members Constabulary Posted December 19, 2022 Author Members Report Posted December 19, 2022 The screw is replaced already. It was the most unimportant screw on the whole machine. It just holds the oil pot in place. I was just super surprised that it split up like this. Manufacturing error - I will check with Dürkopp if I still wave warranty. When the "planets" are aligned like this and the needle is set as mentioned above the machine is correctly timed and sews well.
