Here is the latest update on the Arbor adapters for using Blocks as buffers.
Kevin54 PM'd me with a final few questions and I replied a few moments ago.

Quote" I haven't forgot you and am working on some prices right now. The last you said was that most likely you want 7 sets. How long to you want the adapters to be? This will be on top of the 3" dimension of the arbor already sticking out of the grinder motors.
For instance, on my buffer, the total shaft length is 7" from motor housing to the end of the shaft, but I have 3/4" shafts.
7" total length is OK.
Do you know what diameter of buff wheels you will be running? The grinder wheels you have listed are 6", 7", and 8". Eastwood, has about the best selection of buff wheels. They carry the diameters of 4", 6", 8", and 10". The 10" fits a 3/4" shaft, and requires a 1 horse minimum motor. the others fit 1/2"-5/8" shafts and run a smaller motor.
Not certain what others will be running, but I will post your comments and recommendations.
Would you want me to just make the buff wheel end a 5/8" thread for all of the sets just for simplicity on buffing wheels. Maybe some people wouldn't want Eastwoods buff wheels, but 5/8" should work for all. I know that if a buff pad had a 1/2" hole, it will still go over a 5/8" shaft. There is enough wiggle room in the pads. Then I can make up all of the blanks for the adapters the same size, and the only thing I would need to do is change up the mounting ends for the grinder motor.
Executive decision ahead - 5/8" on ALL to keep cost down.
In doing that, it will be easier to turn everything the same size. And if that sounds alright, then all I need is a length that you and the others would prefer.
7" total length, I think these Blocks should handle the extra forces. If it's too close to the motor, then you won't have a lot of pivot room for parts if you need it. And if it's too far, you have to remember that it is an adapter, and not like a complete shaft running through the motor. And as said, mineshaft is 7", but the pad is at 4" away unless i add another spacer to move the pad out more. Also, you will need four large washers for each pair of adapters. The washers on my 10" buff pads are 4" in diameter. If some of the people buy 6" pads....if you put 4" on each side of the pad, it will make the pad stiffer than normal. So maybe something like 3" diameter washers for all of the shafts maybe?
I agree - 3" washers should be good.
Along with that, what about spacers. My buffer has 2 spacers on the inside area towards the motor. One spacer is 1" and the other spacer is 2" in length. If I had another spacer, I could add a secondary buff wheel on the shaft and run it with a different compound, depending on what I was doing.
Let’s go with 1" spacers. Do you recommend 2/side - 4/pair?
So do you want me to figure in some spacers also? If I make all of the shafts at say 5/8" diameter outside of the mounting area that goes on the motor shaft, I may be able to find some tubing with a 5/8" or a tad larger and just lob off some in the lathe at a couple different lengths.
Yes, please make-up spacers for each pair. " End quote.
So, the project is still alive. If you haven't given me your contact information and which choice you voted for, please make your way over to the Poll and let me know.
BTW - I might be able to accommodate add-ons. Post in the thread, Polling is closed, but you can still post; but on that thread to keep it simpler to track.
Thanks. Mike
