Thread: Dimmer switch for buffer for variable speed ?

Go to Amazon.com and put variac in the search field. On the first page alone they run from $21 - 245.
and I have no knowledge of all this at all ! My background was Equity Trading Systems both software and hardware. I can be good at restoring a blade but making scales ? I dont have the equipment or skills needed. I am sorry I sold my belt sander and scroll & Band Saws before I moved last year !
also
Grinders & Sanders - All kinds
I can search on Pillow Block but what is the proper name of the Shaft ? Can I assume the pulley that goes on the shaft has to be smaller then the pulley that goes on the spindle of the motor ?

I know this is asking a lot but can you tell me what to buy to take my 3450 RPM motor and cut that in say half or in a three step pulley go to 3450 then ? then 1725 ? I would not need to go faster then 3450 ?

Well there's a problem. You don't know what you're looking at. Go to Google and type in "router speed control on my grinder", you'll find all sorts of smart fellahs saying not to do it. The other stuff on page one of Amazon isn't even meant to be used in the way you imagine you'd use it.

Drive shaft.

I probably could tell you DaveN. But seeing as how I didn't figure it was important enough to do for my own set up. I'm not liable to think it's important enough for yours either. If you scroll back through the replies though, you'll find that Gssixgun gave you some formulas, and 32T gave you some formulas, and Randy even gave you some pictures and a video I think. If you're good with simple addition, you ought to be able to put all that together into a nice package. Everything you want to know is a simple act of personal effort away.

Best of luck!

Here is what you want.......W1681 Buffing Assembly

Pay attention to the middle pic...
For your existing motor shaft get the smallest pulley you can find. You will probably need to get a slower motor but try what you have first.

Hope this helps

Be sure to read the PDF manual. Lots of good info.
I did not know this existed before. Unless someone has something better this is what I will be recommending.

Thanks Randy.
At Joe, "You dont know what you are looking at" I think I already said that. And,
That was the most polite way anyone has ever told me to do it yourself !
Best of luck to you as well.

For what it's worth, for three years, I've been using a 3450 rpm buffer from Harbor Freight with 4" wheels. I've buffed at least a few hundred blades on it. I burnt up the first two razors when I was learning and have had no problems since.

Don't use pressure and keep the blade cool. Don't buff the edge.
