What are we guarding?

Re: What are we guarding?

Hi Jack:

The only guards I know about are the one's that attach just above the grinding wheels, there should be 2 of them one for left and one for right.

I think they are to insure that any sparks that cling to the outside of the wheel are stopped from coming towards the person in front of grinder.

They should mount so they are as close to the wheel as possible but NOT touching it.

I don't use the original long arm........

....for grinding any tools, and substituted and modified shorter square tubes from Lowes for grinding mostly bowl and spindle gouges. You could easily cut off a useable length of the original arm for your purposes, and it's a shame you've already cut a hole in the wall.

with homemade handle takes every bit of the Wolverine arm. A picture or better description of the guard you are asking about would help.

If you are talking about the thin metal guards that are round, they are designed to go on in halves. The first half goes on before the wheel, then the outer portion screws on to enclose the outside of the wheel. These are designed to contain the large chunks of the wheel should the wheel come apart for any reason. I am not a fatalist, but I will tell you that regardless of what you have seen, these serve a valuable purpose and need to be on. Note they won't fit with CBN wheels, but aren't necessary with those wheels because they are not manufactured in the same way and do not have the same propensity for coming apart if there is a manufacturer's defect.

not sure either...

I have two wolverines, a 17 year old and a 14 year old, neither came with the guards in question. I looked at the manual and can see how they are used. I've had stalagmites build up under the platform when making tools or during heavy reshaping, but I never thought it was a danger and never had an issue. Maybe someone got sucked into their grinder and this was the fix? I'm definitely going to be more careful...

That's alright. It's my wall and it didn't interfere with anything on the other side. I could have moved the grinder but I like it where it is just behind me when I'm at the lathe.---Jack

Not those

These guards ? *LINK*

If they are the ones Fig 1, 2 at the bottom right of page 1 of this link:

I'd say they are to keep the tool from being dragged in under the wheel if it "slips" somehow. Normally this function is provided by the tool grinding platform which is now removed.

There

have been instances where people try to sharpen too close to the center line of the wheel and get horrible catches that could be serious. That and handling the wolverine carelessly. The guard is there to try and keep your fingers from getting caught but I suspect mostly as a precaution for a lawsuit.

I think Doc Green has a discussion along with diagrams re the dangers of having the tool catch.

I'm thinkin you are right. It has something to do with liability.

I bought mine several years ago - it did not come with those guards. Parenthetically, it is my opinion that using the vee arm as illustrated can be quite dangerous should one have the tool too low on center of the wheel or if the lock should somehow slip during grinding. I use the platform for grinding roughing gouges and skews. I only use the vee arm for when I use the varigrind jig. My grinder sits freely in the shop with no wall interference, otherwise I would have cut a portion of that square tubing off.

Purchased a kit for a friend down in Mexico in December. We set it up a month ago when I was down there.

Yup, the kit did include those upper guards. And, like most of us, they didn't get installed.
