Bladegrinder,

     I tried your tip on disconnecting the brake and it worked! I adjusted the linkage and it starts slow, runs slow, or I can speed it up. Only downside is making sure to stop stitching you have to push the pedal back to the starting position!

     There must be also be a  way to slow down the startup besides removing the brake! Anyone have any ideas?

It sounds like your pedal it hanging up, it should return to the stop position when you let up on it.

Hi, I'm not sure how your machine pedal controls the motor, so I am going on the 2 modern style industrial tables with clutch motors that have basically the same set up, one I think original to the Singer 211G166  compound feed flat bed, the other a union special (flat bed) table that has got my old Singer 17-8 cylinder arm machine fitted on it,  but I might swop that with my Adler Patcher I have on a Singer treadle base for the Patcher style machines,? 

But back to what I found years ago on how to slow down and get more control over the machine is quite simple but quite clever as well, 

The lever that is at the bottom of the motor, it pulls down and operates the motors clutch, at the end of the lever is a hole, the Rod links into, with a bolt in the end of it, the lower end of Rod fits on the pedal. That's what it does, 

What will give more control is making the distance between hinge of the lever and the Rod link at the other end, in the same way as it would give more force for less energy,  it allows increased control because eg the pedal control movement of 1 inch changed the motor speed from 0 to maximum speed,  when the distance between the hinge and Rod link are increased the control movement can be greatly improved doubled plus quite easily to do by bolting a length of bar, angle alli, I think it's uni strut with holes in it,  Channel rail, the Singer table pedal was connected to the Rod on the motor side so I just moved the connection on the pedal to the other side and extended the lever with a bar, I've just noticed the other table pedal is in the middle for a normal flat bed machine and I will probably move it across to suit where the action is and more comfortable, 

I hope you understand what I mean? It does work and when you think about it is quite logical, 

I keep thinking about turning the cylinder arm machine around so the arm is clear over the end of the table,  but I am not sure whether the motor will be OK wired the other way round so it runs opposite direction, DC AND 3PHASE motors do, not enough room to turn the motor round, 

Anyway hope this helps,

Most of the brakes are adjustable or modifiable for when they engage and how much they engage - with a little effort. Others on this forum might have the best ways of doing that. They can be set to stop movement especially if wanting to stitch slowly. Adjusted that way, it won't dead stop things if stitching fast though.
