Most 8" machines run 8" buffers at 1725. 6" machines with 6" buffers too. Usually the 12" monster buffs run very slow. If you are attaching directly on the shaft of motor I think you will be OK. If you want to belt drive a really large buff head Covington and Diamond Pacific both have pulley charts for figuring speeds. Sounds too complicated to me. My Genie buff (5.5") works great at 1725 rpm. So did the 8" buff on my old Frantom combo.

Don't laugh....having trouble wrapping my brain around this.
I was getting ready to order a shaft adapter....I need right hand threads, right?

If you are putting an adapter on the left side of the machine, it should be left hand thread. That makes the wheel on the left side tend to tighten as it turns, a right hand thread will loosen as it turns. In discussion here on the forum about a year ago, some people said they get away with R.H. threads on the left side.

I like my 12 inch leather polishers but with some stuff they take forever to polish because things don't heat up enough. With a faster rpm it's easy enough to slow down the surface speed by working towards the center of the buffer. The don side is if you apply too much polish slurry to the wheel it will fling it all over.

Quartz, I was having the 'righty tighty - lefty loosey' fighting in my head. I understand the concept, but could not figure it out...then I thought I did ....then I didn't.
Thanks!
Thanks Lee! I wasn't planning on slowing it down and now you validated that decision.
I have a Genie, this is something I might (or might not) use to face polish bigger pieces. I like to tinker, I have some down time and some parts, hence present project.
I have about $40 invested so far because I already had most of the parts.
Thanks for the great insight...it's amazing that we all do the same thing with great results and different techniques and opinions.

Now I'm confused. If you mount an 8" polish head (smooth bore with set screws) you won't need a shaft adapter. If mounting a home made buffer it depends on how it mounts. If threaded then yes on left hand thread. You can center drill and thread a hole on the left side with right hand threads but outer threads have to be LH. Otherwise you have to over tighten to keep it on.

Oh no...If you're confused - what does that make me?
This is why I haven't ordered a shaft adapter yet...I have not figured out the polish head configuration.
I am seeing what is available pre-made, before I try to cut out a perfect circle.

Tony bought boxes of polish heads (new I think) from Diamond Pacific at Quartzsite last year. Talk to him before you go too crazy. You can spend your time polishing rather than planning and worrying.

sorry it's taken so long but here is the plexi I had bent for my trim saw.       Any glass shop should have plexiglass and if they have a stem cabinet or a steam bender that can bend to any shape you need within reason. This was done on about a 1/2 hour start to finish. I know it's not exactly what you need but it does the same thing and shows what can be done within reason. It's mounted to a plate of lexan which is being used to elevate the electrical connections as this is an older setup with unusual issues. hope this helps |

Very slick Mario, Thanks! No problem, this is made to mount behind the saw to stop any extra over spray from hitting any of the connections. If you wanted to do a U shape for your expando it should be very easy and not too expensive either... heck you might even be able to trade off some jewelry for it... x-mas is coming soon!! If they can't bend it, let me know, I can get my buddy to do it for 1-2 nice cabbed pendents of whatever (For the Material & bending)... he uses that stuff for presents and collects specimen pieces for himself, depending on the material. Just need a drawing to give him with dimensions. holes you can probably drill yourself. |

Nice job! A polishing head mounted on the left side should not add much load unless you are using both at the same time. I agree that the electrical connections need to be covered. If you rotate the motor in the mounts 90 degrees it will put the electrical on the bottom and the round cut-out for the electrical wires will be pointing in the right direction. Make sure you are plugged into a GFCI as electrical combined with water is dangerous.

See, this is why I need input...I never even thought about rotating the motor.
I have already made a terminal cover.

1725RPM is on the slow side for a polishing head for jewelry. I bought a Harbor Freight grinder at 3450RPM and took off all of the hardware that made it a grinder and bought two tapered spindles for my muslin and felt wheels. I converted this inexpensive grinder because I just couldn't afford a new Baldor polishing lathe on my retirement stipend. I think you have mad a beautiful set up there and just need to make a bigger splash shield to protect the motor. You did a really nice job. I have been struggling for a year to get mine up and running but still am having trouble getting even wetting of the whole wheel.
