Thread: loading greaseless compound

I was wondering if maybe my grinder is too fast. When I go to load the greaseless compound its loads but often goes EVERYWHERE. I'm wondering if this is the product of the speed of my grinder which cant be adjusted.

Thanks
Luke

Quite probably.

You can adjust it by turning it off. As soon as you hit the switch, press the compound against the wheel. When it stops or nearly so, remove the compound, turn the grinder on till it gets to full speed, turn it off, and repeat.

Don't stand in front of the wheel!

If you grinder is fast, you can accommodate for this by using smaller wheels. What speed is your grinder and what size wheels are you using?

its a ryobi 6 inch grinder with 6 inch wheels. It runs at 3600 rpms

The formula for calculating surface speed of the wheel in Surface Feet Per Minute is below.

SFPM = 1/4 x diameter of Wheel x RPM (revs of spindle per min.)

SFPM = 1/4 x 6 x 3,600 = 5,400 SFPM

In theory, and in general, the surface speed should be in the range of 3600 to 7500 SFPM, but in practice for razors given how thin they are, you are much better off near the lower end of that range.

If you have to stick with the 6 inch wheels, you will need a light touch and will have to do a lot of water dipping to avoid trashing your blade.

Be Careful!

When I load greaseless compound its a mess too. Make sure you keep you compound cool ( I Keep mine in the refridgerator) as when it gets to warm it gets soft it splatters every where. Also when loading bump it to the buffing wheel dont just hold it to it that will cut down on the mess and waste

That's something that I hate...all that waste that is flying EVERYWHERE!

I have a shop knife grinder, Foley. It runs on the faster side at around 3200 if I remember correctly. I will turn it on, let it spin up, turn it off then drag the compound on. One little trick. Let it sit for a few moments after every application. It will take a while to get it loaded but the pause lets the adhesive dry a bit before you spin it up again. What is on it stays on it and the grit from the previous application helps to hold onto the compound from the next application. I also put a scrap piece of wood on the outbound side of the wheel so any splatter ends up on the wood, and not on the wall although some does end up on the ceiling now and then. It is just the price you pay for buffing blades.
