Anyone Tried this Speed Reducer?

Good job Rac, thats a nice setup. Plus the link belts are a bonus. I put machined pulleys and link belts on my old craftsman table saw, that thing is so quiet now and no vibration what so ever. 

Extend that arm on your motor actuator and it should give ya even more control.

Nice job! Now, replace that 5" pulley with an 8" and fit a larger pulley on the head unit (replace the handwheel) and I reckon you might not need a servo. It will also have gobs of torque.

Thanks..... will be working on extending the control arm....

I found a high quality 8" industrial pulley with screwed sheave.........real heavy like a flywheel

....but I am at a lost for a larger pulley that will fit the head........ any suggestions short of machining on???

Hey Keith,  I'm sure this is not your problem but in the picture you posted of the servo you have the speed set to the max.  Just wanted to point that out.

There is a real nice video on youtube of the actuator extension.  I just watched it yesterday

Sorry mate, I just realised that your machine is probably similar to my 211G166 and in order to fit a replacement pulley on the head unit a sleeve will have to be fitted around the shaft and fit inside the body of the machine which Is why I haven't done it to my 211 (yet). On most machines there is a bushing/bearing fitted inside the pulley end of the main body and the shaft fits through it. The 211 is different and the pulley (handwheel) is machined to fit over the shaft and extends inside the main body. If you try replacing the pulley then the main shaft can oscillate unless it has this sleeve fitted.

Use the 8" in place of the 5", you should have the room there and it will still make a difference.

I wanted to try out this method since the parts are easy to get and it installs from the top of the machine.. looks like it works well?

I know someone was going to say something about that lol.

Its actually at the lowest setting, turned all the way clockwise.  I thought the same thing too, and played with each setting to see if that was the issue. Backing it counter clockwise it speeds up considerably.  I think its just the cheap chinesse manufacturing in that the labels don't line up with actual settings.   

Thanks for the Video!

I ordered the Speed reducer and it should be here friday. After I get it installed I will report back with pictures and results.  Thanks again everyone for the kind words and assistance.

Keith,

You might want to check the article and video in the link below to see if his method will work on your servo.  Note in his comments that begin about 2:49 into the video, he found by setting the speed range to "0" on his Enduro servo, he had far more torque.  I found that also to be the case on my Consew CS1000.

Yetibelle, that's not a bad solution, as it's easier working on these things from up top rather than clambering around underneath! Just make sure that it doesn't interfere with tilting the head back. On of mine is mounted underneath but in order to tilt the head back I have to slacken the speed reducer first (no big deal but it is annoying).
