no facetime but I may be able to hep when you explain the problem and post some pictures. What model do you have?

I have never seen anything like that - I have no clue! 🤔 I´m not questioning the quality of Pfaff machine but Pfaff IMO made a lot of thing way tooooooo complicated. It it was a Singer 236 I would have a belt driven roller foot.

it will but depends on your expectations regarding sewing speed. You may need a smaller pulley or speed reducer in addition.

what does the manual or parts list say? I`d guess a drain screw or oil regulating screw for the hook.

please post pictures of your machine from the rear and when tilt back from the underside and how you have installed the foot lifter.

the parts list may help you pfaff_471-474-491.pdf

top and bottom picture show a Singer 107w ZigZag machine of some kind, it can sew garment leather. I have one, nice machine but not the best option for leather work. But the one shown has a lot of milage as it seems. I would not buy it as my main / first machine.

if you are looking for small / narrow foot print feet then these feet here may be an option: https://leatherworker.net/forum/topic/132157-interesting-441-style-presser-feet-for-singer-111w-153w-and-similar-like-341-227r-and-so-forth/

My response was a bit short I guess. Well, we have not seen the machines but I would assume that the 211´s are old factory machines that probably have been stored for maybe decades (we do not know, do you?). You for sure will need a new motor (Servo motor + maybe a speed reducer for better speed control) and depending on the wear you may need a new hook and maybe a new timing belt. Replacing a timing belt on a 211 is no fun work IMO due to the shaft bearing on the hand wheels end. So if you are able to replace the parts by your self. And since we have not seen the machine it may need some more bits too. You may need $100+ for the motor + maybe $150 for the speed reducer (if needed) and maybe $50+ for additional parts (all guessing) and your time for repair and adjustment work. So a lot of guessing here. Pictures of the actual machine(s) may help. The machine it self could probably sew what you what (as AlZilla already said) but it is meant for flat work and not really for sewing over thicknesses. There are for sure better machines for leather work. Triple feed machines are a lot more versatile than needle + drop feed machines, especially when it comes to accessories like presser feet and so forth. My 2 cents.

its a needle feed + drop feed machine w/o reverse. you find some main information in the service manual (1st google hit on my end) I would not buy it. Singer 211W151.pdf

And there is is 😉

College Sewing is back: https://www.college-sewing.co.uk/catalogsearch/result/index/?cat=3&q=tapered+bore&p=1 but I´m sure most sewing machine dealers in the US can get you tapered bore pulley as well. Maybe worth checking with Toledo Sewing Machines

check with LW member @shoepatcher - he has a lot of odds and ends and is collecting and refurbishing patcher machines of all kind. Link him to this page, maybe he know more than I.

What country do you come from? College Sewing and Trojan Sewing in the UK have tapered bore pulleys. I cannot reach the College Sewing website atm seems it is down for maintenance or so https://www.trojansewing.co.uk/?s=tapered&post_type=product&type_aws=true

small one in my case is 17.4mm in diameter and 8mm fence. so I really think you have a small hook machine.

I have kept some old shuttle drivers from a parts lot I bought some years so. The one on the left is close what you measured but I have to find my caliper... but I´m almost certain that yours is the machine with the smallest hook. Later more...

I'll get a new left toe foot but have to place a new order - thats okay for me considering the fairly low price of the feet. They for sure have something I could use. I also found some interesting cheap feet for the Adler 67, 167, 68, 168, 69, 169, 267 and so forth "line" in their store: https://de.aliexpress.com/item/1005008687919538.html nutin for me Singer Idjit but looks like a good deal for the Adler folks 😉

Here is a parts diagram of the Adler 20-20 - hope it helps Adler_Parts_class_20-20.pdf

I may have a hard copy of the 20-20 parts list, not sure though. I´ll check that in the days to come... stay tuned... 😉

cannot edit anymore. Here are some pictures:

They have arrived! Took 10 days from China to Germany and no extra charge. I´m using them on my 111G156. First glance.... The "fork" foot set works fine and line well with my feed dog - no issues. The right toe foot is touching the thread guide but the one I have installed is not the "original" one I have one from a 211 so that is on me. The left toe foot does not fit into the foot bar. The end that goes into the foot bar fork is a bit thicker than on the other feet It also has a different finish, the other feet fit well. Maybe I´ll do some grinding but I´ll check with the seller first. The scissors are sharp a hell. I ordered them for just having a pair in my tool box. REALLY SHARP!!!

seems I´ll get my order within the next few days.... curious me is 😉

since you are in the USA I´d contact a sewing machine dealer in you area. I´d probably check with Toledo sewing machines https://www.tolindsewmach.com/parts.html They for sure can get you the parts you need or even have them in stock.

Be as you are - why faking around on dates? No rules IMO. If it´s not working then its not working. Was not working at the 1st time, right? So do not put too many expectations into a date, let it happen and see where it ends. You never know (as you have experienced). Just don´t be rude and not excessive friendly.

here is a parts list that tell you what it originally was designed for. Its basically is a tailoring machine that is surely able to sew some garment leather. if it need parts google the part numbers or post pictures of your machine so we try to figure what could fit from other machines. Feet seem to be the type that is used on 107w, 143w, 457w and so forth (straight stitch). singer 150w104 parts list.pdf
