Steel plate table top?

Personally, for $20 more the slightly larger csm3000 700watt would be a better motor.   Both of these aren’t known for very good low speed operation, so a speed reducer is a must have to get good control.   You’ll see these motors sold under half a dozen different names.   Essentially the same motor design is used a lot for a number of different sizes sold by various people up to 1500watts.    I have a 1200watt model that has very good torque down low and is my favorite, but it was twice the price for twice as many watts.

The family fesm550 servo is generally accepted as a better low speed servo, and bang for the buck is quite good, but it’s not nearly as compact and to me looks funny when used above a table.  It’s also sold under half a dozen different names and is a very good choice for most sewing machines and most people.

I do have a family fesm550 on my Seiko with a 2.5 inch pulley ,set at 600rpm , very controllable .The cylinder arm singer is much two fast 3200 clutch motor .So your right angle gear reducer came with a shaft for drive belt pulley ?And u said other side bolted right up to your motor huh. Haven't seen one yet like that. Went on Wittenstein website to get familiar . Can I get a few more different pic  angles of your motor set up? Really need to build some space saver table. Another Gentleman on Craigslist just gifted me a working Singer 133k18 darner machine with table and 3hp motor . It's crazy powerful ! Got 5 machines in the Hoard.LOL Garage is packed . 2 machines in living room !

The output shaft of these reducers vary in size a lot - some are metric and some are inch size - you just have to order a pulley to match the shaft.   There is some drilling and head scratching with these - definitely not a simple bolt on, but not overly so.

You have to keep looking at eBay every week or so until one comes up for a decent price.   I’ve had the best luck searching “Wittenstein reducer”, looking at a few of the lowest priced used models, and then scrolling to the bottom of each page where similar items are shown. Then I’ll repeat that and search just for “alpha reducer” Almost every one I’ve picked up didn’t show up in the main searches - eBay has turned into pay-for-play just like Amazon.

Thanks!  It was fun.

I came across a home made 3:1 reducer used to drive an electric hydrofoil board thing.   It uses the nose of a small grinder - apparently the rotor shaft going into the nose is supported by a pretty good bearing so guys cut the shaft leaving an inch or so to attach a coupler to, and fabricate a spacer to fill the gap between motor and grinder casting.  A 10mm to 15mm rigid shaft coupler is $20, so it seems all a guy would have to do is come up with a 2”ish spacer for sewing machine use.  I may try this just for something different.  Lol
