What is the bobbin size for this machine? I might have a barrel type bobbin winder sitting around somewhere, if memory serves.

Head over to the Ebay and be prepared to buy the servo separately. Unless you come across a local shop which has what you want. Motors are normally sold with machines, not with tables.

I knew it! It did look Mitsubishi to me.

Might as well wrap a few loops of cotton wick around the needle bar and leave it there. As to resting your foot on cloth - you should always do that. Never let the foot rest on the feed dog as that wears both much quicker.

It's chain-stitch. Definitely not a leather machine.

I have this exact model and it is missing the sliding cover on the left side of the bed. If anyone has one lying around, please PM me! I'd prefer one in Canada and US, but elsewhere in the world is fine as long as the shipping is not too much.

Could be Pfaff

What kind of polymer is this? Glass impregnated nylon?

If your old 220V motor is a clutch motor, it is boat anchor. You could get a few bucks for it at a scrap yard, or wait for years on Craigs list for anyone to buy it for 20-40 bucks. But if it is a servo, get an inverter and stick to it, as it would be miles ahead of any 110V servo. I guess it should be a servo motor as you have a pneumatic cylinder sticking out from the back of the machine.

What size needle and thread are you using, by the way?

Does it correlate at all with the wear on the needle? I.e. does a new sharp needle work better than an older dull needle?

The temptation of 3d printing a small pulley is almost irresistible. I am going to try it tonight.

China works in Imperial and Metric depending on the order. I own custom order taps in fractional inches made in China and their quality is superb. As they use almost 100% CNC machines, it matters not what unit the blueprint/model uses. North America can continue using imperial units just fine even though it gets much of its goods from China.

Depends on what you plan to sew, a servo might work, or a servo with a reduced pulley. How many stitches per inch are you interested in? The shorter the stitch, the easier it is to saw. If you have to stitch 4 SPI/6mm stitches, it can be hard to control at first.

Imperial or metric really makes no difference for CNC but if you have a manual lathe, it does one or another but not both. Imperial fractional wrenches and socket heads are very straightforward: they either do not fit over the bolt head, or spin freely. With metric sockets it might feel like you got an 11mm bolt, but in reality it is 10mm and you have to test 2 sockets, or you are rounding it. I hate metric bolt heads even though I was born and received my engineering degree in Europe. Standard metric M threads are finer than standard fractional imperial threads. Each has its own uses. Imperial thread as fine as the standard metric thread requires a non-standard hard to obtain tap or die. US and Canada should stay with imperial and Europe should stay with metric. Says a European expatriot.

It could be just an unscrupulous crook's spamming attempt, which it likely is. "We are the dealer" adds weight to the listing and they are hoping somebody falls for it.

If you fit pulleys to shafts often, look for a set of adjustable reamers, but stay away from the soft made in China or India fakes. I bought one of those fakes from KBC Tools in Mississauga, Canada, to compliment an incomplete Made in the UK set I had, and the the square shank twisted as soon as I started rimming. Returned it and the salesman said yes, we know... Why sell them then?

However surprising this might sound to you, old leather furniture could be the cheapest source. Whenever I see an old leather sofa on the road side, I cut off the back and sides and use for training/experimenting. Do not confuse leather with vinyl though lol The modern "ecoleather" could be surprisingly similar to genuine leather in looks.

Yes, they come with and w/o pneumatics, and the automatic machine is approximately $300-400 more expensive when used. The head weights about 80kg. I know - I carried it to the 2nd floor of the house once.

If you are serious about industrial sewing of knits, you would curse everything if you bought a 5-thread coverstitch w/o an automatic thread trimmer. I have the Kansai 5-thread coverstitch which is almost identical to the pictured machine and if I had to cut threads by hand instead of reversing the pedal up, I would hang myself. Save some money for an automatic machine and a compressor.

I happened to be at the local sewing machine shop before reading the above, and they showed me DAX1. They are even shorter, than DBX1 by about 2mm. Sounds like all I can do is lower the needle bar for DBX1 as I still want a longer needle.

Greg, Do you happen to have textile needles in 88X1 in sizes 70, 80, 90, ideally TIN coated? If you do, where and how can I order them? I am also looking for the throat plate for the same machine, marked in metric units. I know it shows up in searches around the world, but most suppliers only carry fractional inch marked plates.

Got it. DAX1 is different from DBX1. I missed that part.

Cannot do: I no longer have the old needle.
