  1. That should work. The other option is to drill and tap that other one for a second screw, which I've done on a couple of pulleys. I've run a smaller belt like that and so far it's been fine. There is a possibility that it may slip, depending on the fit in the pulley, but so far it hasn't been an issue for me. The alternative is to fit a larger belt, which will then ride a bit higher on the motor pulley but will still work. The only potential issue with a wider belt is that it may be be a bit stiffer. I've done both. This is one I've just finished - As you can see the belt is low in the pulley, but it has driven a size 24 needle through 1/2" of veg without slipping/stalling.
  2. Fitted my (cheap) servo and I must say it works well. I have to set the max speed fairly low otherwise it takes off too quickly for my needs, but it has plenty of grunt. My Organ leatherpoint needles also arrived today, and using the knee lift I can just shove 1/2" of veg under the feet and it handles it easily (#138 thread/size 24 needle). I wanted to use the original Singer pedal ('cos it looks cool) but there were a couple of problems. It was too high to comfortably use the knee lift so I made some brackets and lowered the supporting bar, and because the pivot points are behind the balance point the pedal had a lot of forward weight so I used a piece of elastic strap to take some of the weight. Seems to work ok. I had to open out the hole in the feed dog as there wasn't enough adjustment to centre the needle properly (the 117 doesn't have all the adjustments of the later 111W15x series). I had to make a couple of attempts at this as it was cutting the top thread on the upstroke! A bit more care and lots of polishing fixed that. Next problem was the knot was sitting on the bottom of the leather, I couldn't get enough top tension to pull it up. Replacing the beehive spring on the tensioner with a stiffer spring fixed that (I've no idea where the spare spring came from, but it fitted). I'll leave this set up purely for #138 thread, although I wouldn't be surprised if it could handle #207. Maybe later....
  3. Strange. The only way I can think of for a needle to break like that is if the hook is catching it (I've actually done that, before I understood how to properly adjust things). All my other breakages have been on the downstroke due to needle deflection and hitting the feed dog.
  4. Must be something in the water over there then..... R8R, even though my instructions don't show them, I can cycle through and see the same settings that yours has. The rear connectors are the same, other than the 2-pin on mine is set for an LED. I've got it working but found that to get the slow speed control I want I have to set the max speed low, about 800. Above that it takes off pretty suddenly and doesn't seem to have the slow ramping that my others have. It's rated at 550w (who knows what it actually is) but appears to have plenty of grunt, doesn't have any trouble stitching through 1/2" of veg with #138/size 140 needle.
  5. That is beautiful (and quite elegant)! That stamping must have taken a while.
  6. Ahh, that makes sense. One question solved.Thanks mate.
  7. I've no doubt that the sp-1100 is a good motor, but 1 1/2 hp seems a bit of overkill on the Consew.
  8. Very interesting. There are definite similarities. Although my instructions stop at 22, I think it continues to step past there so I'll have to do a bit of experimenting. P11, speed lock, has me intrigued (?). This seems to add credence to the idea that many of them may use the same circuit board and just disable the features not needed. Mine doesn't have any markings to indicate brand so it's presumably just a generic unit supplied to various companies, the build quality, while ok, is definitely not up the the standard of my other servos (made by Lishui).
  9. My servo arrived unexpectedly this morning (the tracking still showed it in transit "somewhere"!). I was concentrating working on a trigger in the shed when he came in, gave me a helluva fright!! Anyhow, for what it's worth these are the "instructions" that came with mine. Looks like I can reverse the motor just by pushing one button (dumb idea!) and turn a LED on /off. I'll have to see what sort of voltage that connector is putting out. They must use gorillas on their production line judging by how tight the mounting screws were!!
  10. Pfaff 335 17b h2L stitch problems

    Sounds like you found someone to fix it who knows what they're doing.
  11. Man, the planets really aligned for you!! That is a good buy, as JLS said should handle up to #138 thread/23 needle. For what you paid for the Rex I'd keep it (if you've got the room). Now just try and stop looking for bargains!
  12. My latest servo (overdue delivery but hopefully any day now) has a 4-button control unit. It's a long shot, but I'll try and see if there's any correlation to yours.
  13. I found, much to my annoyance, that many of the options/settings on my two-button servo were disabled. No idea why.
  14. I suggest you start a separate thread asking for info on the feet it uses. If you're lucky they might be the same as one of the Singer models.
  15. Not really big enough, in my opinion, particularly if you're going to try and get a clutch motor to crawl. I tried various combinations of speed reduction, using a clutch motor, when I got my first machine but I could not get it to go slow enough (or control it!). So I bought a servo and made a speed reducer - much better. I didn't hesitate when I bought a couple more machines and ordered servos straight away. By all means try it with the clutch motor, but don't expect to to be able to sew stitch-by-stitch.
