That armored tee-shirt saved you. Sucked up the energy of the spinning bit. EDIT: 7th grade wood shop teacher was missing a couple of fingers and had a scar on the same wrist, having almost lost the hand. Years earlier his necktie got caught in a wood lathe. Maybe that's why I don't have all the great war stories you guys do ...

Yeah, I knew somebody would spot that I burnished before I glued ... Normally, I would glue/sand/burnish. It also would have flattened that edge and avoided the little stitching hiccup on the back. Appreciate the comments ...

Yeah, mine also take a bit before that servo light blinks out. All of them. If I watch, they all flash "err 2". For me, "Off" means lights out. Especially on that 441 clone! EDIT: I forgot we were talking about those torque monster clutch motors. Absolutely, if that bad mother is spinning, it's "ON".

Thanks, guys. In the harsh light of pictures, it looks like I could decrease my presser foot pressure.

Have you looked at everything the thread touches and slides across to be sure there's not a burr somewhere? Come to think of it, have you looked to be sure the thread is feeding smoothly from the spool?

I think my next project is going to be fabricating a couple of hinges out of angle iron. It is a genuine PITA trying to work on this thing, flopping around on the bench ...

That whole post should be a sticky entitled "When Your Sewing Machine Skips Stitches". I'm going to print it out and go through all my overlooked check springs the next time I have to work on my machines. Thanks for the time and effort putting that together.

Generally I just make functional things, including this one. But I thought I'd post it anyway. I bought a cheap Tractor Supply knife, put a razor edge on it, cut the junk sheath apart and used it for a template. Here's the result. Machine sewn, for the curious.

This was my concern, that this is going to devolve into a string of DND links. If the members want to have this conversation, no problem with me. But we have enough trouble with the Minecraft spamers. No need to add DND to the list.

Let's move this to Off Topic. I'd use a firearm to kill a cow, skin it and tan the hide, then cut the strips I need. Unless your realm has a leather store like Tandy.

You could put a binding on the edges to hide and contain the interface between the liner and exterior. It's a folded over piece of your material of choice, folded over the edge and sewn. Pretty common on all sorts of things - clothes, gear, carpet and so on. You've seen it a million times. The rest of it, I don't have a clue.

You need to tell if if you're willing to ship this thing, per the forum rules. Thanks

Is that a very long strap, doubled over around the buckle to give you 2 layers? Very tedious work. The overlapped stitching isn't noticeable until you look for it. Very fine work!

Is that a clutch motor?

You'll be glad you did this repair. It's not nearly as difficult as it seems. I think your machine uses Allen screws, if I remember right. If it's slotted screws, you'll want good, hollow ground screw drivers in the right size. Let us know your it goes. Maybe you'll inspire the next person.

I wrestled a little with this post yesterday and decided not to respond further. To me, giving (whether a brand new car or answering a question like the OP presented) is done without expectation of any return or even a thank you. So, I wouldn't boot someone for not checking back in. An acknowledgment and thank you would certainly encourage more dialog, but people seem to be pretty self focused these days. Maybe he forgot where he posted the question ... It was really kind of a fragment of a question anyway, not really enough info to give a coherent, specific answer. I think Chuck nailed it - pretty much any information a person needs is somewhere here.

I'm pretty cavalier with the domestics, but the industrials I (usually) shut off. A good reminder,

Yep, that is a lot of work. Very nice work, too. You would be doing all of humanity a favor if you uploaded your images directly here. Unless you plan on leaving them on that 3rd party site for all of eternity and saddling your descendants with maintaining them in perpetuity, they'll disappear at some point in time. Imagine how disappointed someone is going to be 400 years from now, not knowing what that ancient belt looked like ...

Exactly. And people will spend long money for the latest and greatest. Thousand dollar cell phones when a $40 phone does the same thing, handgun optics that cost more than the handgun they're attached to, the list goes on. I believe what OP was saying is that they already have a 50 RPM start speed, so no need for a 5:1 gear reduction. I also think there's a language barrier involved. I don't know any more than the rest of you how sincere he is, but it's a worthwhile discussion. Definitely got me rethinking some of my choices. Wiz's comments above have made me wish I hand't turned my nose up at those outdated brushed servos! EDIT: Let's not forget leather stamps. Look how many people buy $50 big name stamps when a $7 Hobby Lobby stamp is pretty close.

I wouldn't get too wrapped up about price. Lots of people splurge on expensive stuff for their hobbies. Lots of people here drop thousands on a machine anyway, what's a couple hundred more for a cool motor? And bragging rights? I've never found easy availability of the HM-750 in the couple of years I've known about it. I don't even know what they retail for, so will we even be able to point and click the new wonder motor you guys are designing?

Looks like someone moved the hook saddle over, trying to disengage the left hook. You can see the extra gap between the needle plate and bobbin case. That lets the tab on the bobbin case hang up on the stops under the needle plate. Might be an easy fix. Whoever had it before was sewing single needle. Another tinker while I await the motor ...

Some follow up would be nice just to see how it actually worked out. But in the end if someone asks about XYZ sewing machine for a particular use and gets good advice, then it's here for the next person who comes along wondering the same thing. This place is pretty much Encyclopedia Britannica for leather sewing machines.

You never know if the person is visiting w/o logging in. It always does seem like they should at least acknowledge the responses. But, that's the world we live in now, I guess. Get off my lawn, too.

It does appear to have been used in a few different machines, lucky for me. I think this machine is the ancestor of the W&W D12, except the couple of pictures I can find of the D12 show a single bobbin serving both needles. This is by no means definitive, just me searching the net.

Thanks for taking the time to send this along. It's quite close, a good clear copy and has an Adjusters section, which I don't have. Very helpful!
