Need a favor from a fellow R4512 owner. I just bought a used one and it didn’t come with the arbor wrenches. Can someone tell me about how thick the open-ended 22mm wrench is? A buddy of mine is going to grind a wrench down for me and I want to be sure I get it right the first time.

Thanks!!

3/16” is what my wrenches measure. I wasn’t using a very sophisticated caliper to measure with though.

Edit: Now that the storm has passed, I will go out to the shop and look harder for my calipers. I think it might be closer to 1/8”. I will return…

Edit No 2: Okay, found some good calipers and it is jus a smidgen less than 7/64”. Sorry for the earlier info.

I will blame my first guesstimate on the lightning. I was in a bit of a hurry. : ) Actually measures just under 7/64

Just measure the flat on your arbor. Most arbor wrenches are nothing more than stamped sheet metal and are always thinner than they need to be. Measure the flat on your arbor, which you have in front of you, and you will know the MAX thickness it can be. Anything less than that width will be just fine.

This does assume you are not talking about the wrench to remove the arbor/blade nut – which can be any size. Also, keep in mind that you don’t need to use an arbor wrench on the opposite side of the nut. I can’t remember the last time I actually used one, but I know it was many decades ago. A scrap piece of wood and a blade wrench is all that is needed, and why those pesky wrenches so frequently go missing!

Cheers,
Brad

That was what I was expecting, but the saws previous owner jacked up the threads on the arbor a bit, so the hut gets a little stuck on the end of the bolt. By the time I put enough torque on it to turn it, it turns the whole arbor while the blade stays stationary. :/
