stil have not found the problem with the tread jamming. see allot of videos, but either they show nothing or extremely to much XD

With the motor disconnected, and the bobbin cover plate slid to the right, you can watch stitches form as you turn the handwheel. Once you can identify what it looks like when a good stitch is made, and what it looks like when the thread jams, you can start to trace out how the jams are happening.

yeah thats the plan. open it up and see where it goes wrong. get some good lighting going and see whats what

the good news is. i finally got it stitching

the bad news is that it inst pretty or good.

keeping the smallest stitch length its stitching just not good looking.

but when i turn it up for longer stitches it starts messing up badly.

so what does everybody think ? is it a tension problem ? any advice would be apreciated.

i took apart all the stuff inder the needle i sanded down rough edges and cleaned everything. but didnt find any burrs or nothing. the under side of the feeddog had some carving that was weird in my opinion 

and everythime i used the knee lifter i heard a click and i found the problem.

the bracket that helps take the tension of the top tread when lifting the feet was broken

and the home made a piece that slips off and dont do much. so ill go look for a replacement for that.

already spend 3 days working on this and i was ready to give up and bring it to a mechanic. 

but i learned they are hard to find. and the ones i called dont do it anymore only domestic machines.

so that sucked. i need this machine to run and work for me. cant keep fiddling for ever on this.

and dont have the money to buy another one and find that that has problems to XD

You have skipped stiches and a nest bellow? Have you checked the timing of the machine?

here is one document, check the added text at the end
https://docs.uwe.net/Pfaff-145-545.pdf

you can also check different pfaff 1245 Service manuals which have nice graphics. It is much newer machine but certain things are same / similar etc

I see tension issues. You mentioned an upholstery shop, so I'm not sure if you are new to sewing or an old pro. Have you experimented with different tension settings to get the looped threads under control?

For photos, do you have some white thread you could use for the needle thread so we can easily see which is top vs bottom?

im an old pro. ive had a upholstery shop for 15 years. back then i bought a new durkopp adler 267.

i used that machine without issues all that time. but i was moving and sold my house and workshop.

then the sellers of the new place upped the price with 50k so i had to shift my focus to storage.

my house and workshop is packed in 4 20ft containers and i have a old farm shed storage hall.

as im looking for a new place. 4 months in and bored waiting to find my new place.

i thought lets buy a little machine and do a little work. small budget as im paying rent and storage fee,s

this one was suposed to be working just needed a little maintenance from sitting a few years.

sadly i was mistaken XD so i just wanna get it running and make little projects i can sell again.

i cant unpack the storage containers so i have been buying little things here and there

to set up a temporary workshop. i have black red and orange thread at the moment so i can do 2 color.

ill get to it tommorow again hopefully

thanks man you helped me out big time. i printed the last part of the pdf.

and started working those tips and it worked. she is sewing.

[VinnyK]

wel with the help of a manual on pdf i started working out the tensions below and above and she sews.

the upper threat

and the bottom thread.

i tried opening up the stitch lenght and she got messy real quick. so i kept tweeking the tension

and slowly its getting better. so im gonna go for the bigger stitch length and set her up for that.

so i can atleast sew the basic stuff and not mess with it to much.

so my next step is putting on the smaller pulley. but geusse what. the axle is conical.

and the new pully aint. even a tiny bit bigger so it slides over the entire shaft.

so im gonna dril a hole in the axle and make a stop with a ring on it. put the pulley against that.

and im gonna make a special filler ring to fit over the conical part

and stabilize the pully so it turns perfectly straight and not woble or anything.

but im happy she is sewing. also gonna laminate the table with a cheap top so it looks nice and works smooth.

eventually clean up the frame and paint it and all.

but first she has to make some money before she gets more love 😁

Congrats. It's always gratifying to get them sewing again.
