Angle Grinder Set up 

Good one👍

Good demo, you are good at explaining.

I was thinking the same thing and also a new user. I'm guessing there must be an adapter available just for this purpose. Otherwise a flat washer could be modified with groves or nothes using the angle grinder [I think].

Don't. Adding a shim to move the wheel down is not necessary. This is the first time that I've seen someone think it is necessary or desirable. That said, you can purchase a spacer if you measure the shaft diameter. But the fact that you cannot find "grinder spacer" should cause you to wonder about the necessity, given the fact that there are hundreds of millions of the grinders in use worldwide. Conversely, if you deem them the next most popular addition to the grinder, setup your tooling and mass produce them.

You probably figured this out by now, but that unthreaded washer he calls a shim comes with every grinder you buy.

@@timrich6755 same question! Do i need the washer that he called a shim at the 4:26?

@@tamaica7770 Why do you think you need it? Does something not work? I've never needed to add a washer/spacer to my grinders, or any that I've used. Remember: safety first. Use equipment modifications engineered for the grinder you're using.

Check the orientation of the bottom spacer and the nut. Typically you want the bottom spacer to have the raised rim facing out from the tool (registering the hole in your wheel on center). Then make sure the nut has the raised rim also facing out away from the disc. There should be a slight depression on one side of the nut to avoid bottoming out on your bottom spacer and bypassing the disc. Diamond wheels tend to be thin, and I suppose it is possible for a no-name import grinder to not have enough clearance to bite down on the disc, but I’d be very surprised if that was the case. Bottom line: any disc you put on the grinder should only spin with the tool’s arbor when properly installed. And yes, it should only get tighter as the tool engages the work. If the disk is rattling free while in use, something is not right and you will need to sort it out before using it safely.

They might be spacers to fit different size arbors than yours. The inner rim of the wheel should fit a feature on your arbor nut or the existing spacer that came with the grinder. It shouldn't ride directly on the threads of the arbor. If it fits snug and runs without vibration, you are probably good to go. Just be sure to wear your safety gear. I always wear a face shield when using a cutoff wheel on a grinder. They have a tendency to shatter if you run them wrong, so keep that guard on and stay safe!

@@robdamico5304 Thanks for your prompt response. You're helping us all out a great deal !

I learned how to use one in 5 minutes at work from a specialist, guys like my dad now. I do large amounts of grinding and welding.
