I want to use it with my PowerPro for bandsawing and maybe to turn large items.

Think the speed reducer will put an end to the bucking/slamming that the PowerPro does with the bandsaw?????

Might make it 'worse'!;)

I don't think the dad ever used it. I set it up according to the manuel, but there is a 1/64 in of wobble in it. Maybe that is normal. I have noticed that one belt does feel a little tight. I am going to check the numbers. make sure they are the right ones.

Thanks for the information

This may be a rumor so don't take it as gospal but I think some Speed Reducers were manufactured incorrectly causing excess vibration and wear on one of the belts. I did not notice it when I used it but when I sold it the person who purchased it complained. If I remember correctly they were able to fix the problem possible with help from Shopsmith customer support.

I did not see any use for it after I upgraded to the PowerPro.

I have wondered the same

. I think we have at least one member who has both accessories; he did some weedwhacker string-winding with his PP and the Speed Reducer.

Is there a history of failures like this? If not, a single failure does not indicate a manufacturing error of but possibly ONE speed reducer - yours. I would be more inclined to suspect user error of some sort given this sample set of one.

Did you give Shopsmith an opportunity to address this? If not.....well, enough said.

What is in a speed reducer? Is it just a sheave?

I have taken mine apart and inspected it more closly. The output shaft is bent. It did not look used at all. I think SS sent out a bad unit to the guy I bought it from. It just didn't get returned, but it is not SS problem any more. I do like how slowly it turns. The replacement part is 88.00 plus shipping. So right now I am not sure what I am going to do with it.

Check with bill mayo. He may have a part OR he may be able to straighten the shaft. I know that he straightens the cutter head shaft on jointers.

Thanks for the info.

Is Bill Mayo on ebay?
I was thinking of trying a local machine shop. It is not that complicated of a piece.

Years ago, I built a jig of V vices with a dial indicator to fit on my hydraulic press to straighten shafts. However, I have not been able to straighten any Shopsmith quill shafts to get them to less than .002" runout. Also, I have unable to find anyone with a jig or setup that can straighten a smaller shaft that would be cheaper than the replacement part. I have gotten lucky straightening a few other kinds of shafts but most often was not successful.
