I might have some 20 ga brass laying around I will look. Could donate to the cause ...that is if I can find it. If Rio Grande has fast shipping, no donations will be required😁

Run ‘em through a rock or two—knockin’ off the high spots—then worry about a few thousandths. That will be the plan we go with.😋

Can you raise and lower your moter to controll width?

Can you raise and lower your moter to controll width? No we can't raise the motor but we can slide the bit on the shaft to reset width of cut. Lots of unwanted adjustments. It would have been nice to get bits that weren't all over the place measurement wise. Oh well, it's probably something we would need to do sooner or later anyway.

Yep, we got standard ground delivery. Said when we chose it that it could take more than ten days to arrive. I guess we'll just keep cutting cabs and grooving them until the wire finally shows up.

To finish hubby drilled the motor mounting holes. It worked. All the holes lined up. The motor mount holes are drilled after center punching. Motor and bit in cutting position for the first time. The motor tilted up for bit changing, pan cleaning. The groover in action😁

We have this one lightning stone where both sides would make a good front side. We are thinking about running the groove around the middle and cabbing both sides. The stone is wide enough to pull it off. Does anyone ever do that?

I purchased 2 different groove bits several years ago from Inland Lapidary. One was listed as 1.0mm & the other 1.4mm. I almost always use the 1.0 bit, both for flush mounting 18ga. copper and also "setting" twisted wires of smaller gauge. I measured the 1.0mm, and after a fair amount of usage, the bit measures from 1.0mm to 1.2mm, as measured w/ a HF composite digital caliper ( I'm sure Hubby's is more accurate). The 1.0 mm roughly translates to .040", and the 1.4mm = .050", so we have the same bits. I rarely use the 1.4mm if that helps.

Works great. Thanks for sharing. I'm sure you have motivated a lot of new groovers!

I just grooved four cabs in about twenty minutes without looking.
Hubby mentioned that he might need to drill more holes in the motor mount to allow some air in the shaft end frame cooling holes. After the four cabs the motor smelled a little warm. It wasn't more than just a little warm to the touch and it has a thermal protection circuit, but, better safe than sorry he figures and will make the mods. It might even just be that new electric motor first time really run smell.
It really works well at making grooves smoothly, quickly and accurately with little effort and no tedious groove depth checks to interrupt and slow down the process. Just keep turning the stone into the blade till it quiets down (when it gets quiet the cutting is done in that area and you can move on) then turn some more until the ends meet.
Now, if I could only convince him to come out of retirement and sell these puppies.

Remember to use a GFCI outlet or GFCI extension cord

Remember to use a GFCI outlet or GFCI extension cord Always a good idea. However, I happen to know that the grounding in this particular device is functional. A ground fault circuit interupter is designed to prevent shocks due to a malfunctioning ground caused by insulation issues on heavily used devices. In a properly designed and grounded circuit, even a direct short from hot to ground should immediately trip the circuits breaker preventing injury. It's when the ground is not functional and a short happens that the current will follow you as the shortest path to ground. Not saying gfci's are never needed by any means though. Always have outdoor, bathroom, and kitchen circuits protected by them. You know your stuff!

That 15 or 20 amp breaker ain’t there to prevent injury or protect people. A GFI will. And it doesn’t care if the ground is properly designed or functional.

So now it is all said and done, what is the final price tag? Vic

Circuit breakers are designed to provide overcurrent protection for equipment and wiring, and do not provide personnel protection. GFIs are not designed to provide circuit overload protection for equipment and wiring.

Just because a GFI is rated for 15 or 20 amps doesn’t mean it’s supposed to trip at 15 or 20 amps.

I've had a 20amp breaker hold and take out the 500amp breaker ahead of it. Never had a problem with gfci's
Time to get back on topic.
