Those are Lortone saws.
My 18" Great Western creates a lot of mist, even with Bardahl No Smoke. No openings in the hood, but I have to let it sit for a minute before I open the hood if I don't want mist escaping into the garage.

I use mine in the garage at the moment, but the oil mist is starting to coat things near the saw. I would not want to use it indoors. I'm not concerned about the health effects as much as I am the mess.

Montanas can look very nice with thin slabs...but that may be too thin.

Very cool. I'm glad you stuck with it to get the shine.

Yes, the last ones are Montanas. Candle them before you cut them so you know how to get the best out of them.

Good advice from Don. You might also try a little belt dressing on the belt.

Hey Don, what you do in the privacy of your home is your business! We don't need to hear about it. :nono: Men enjoy playing with their rocks no matter what their age. Chuck

Diamond is not nearly as hard on the fingers as SiC, but the edges of diamond wheels are sharp! I guess you've learned what you can do with an expando drum now. Experience is the best teacher! I think your 120 diamond will actually cut much faster than a 100 SiC. As Clyde said, go easy on the pressure or you'll be back to spending a lot of time on the expando taking out scratches. Chuck

I have a UV18. It works great, but it takes a _lot_ of rock to keep it going.
Make sure to get the Industrial model. The regular ones can't handle the load.

Yes, I remember the Vincennes incident. I read some of the investigations in about 1989-1990 and made a timeline of events. I didn't read the full account in wikipedia, but as I recall (and I'm not trying to justify American actions), the airliner was not right in the middle of the air corridor, whereas they _always_ flew right down the middle. So that made it suspicious.
It was also reported that they got a radio hook on an F-14. Speculation was that it was taking off from another airport about the same time. Meanwhile, the Vincennes was chasing down some Iranian Boston Whalers that had fired upon her.
Anyway, surely a tragedy and in part due no doubt to the fog of war.

I can't quite envision how it works, Don, but I'm curious about it.
Just the same, it will probably take me about 10 minutes to do next time, now that I know what I'm doing.

Yes, thanks for pointing that out, Steve. I just wanted to share it again with my experience.

I don't have any experience with either, but it seems like the vibrating laps require some babysitting. There are people here who get good results with both.

You bet, Charlie.
When it starts getting old and hard to work you can add a little beeswax.

Nice haul Donnie!
The only ones I could ID already have---Montanas, Dino Bone, and maybe Sodalite.

Due to some problems I was having with my 18" saw, I swaged the old Felker notched blade for the first time. I wish I had done it sooner! Dressing the blade will only go so far in bringing a fresh cutting edge. My blade used to bog a lot (especially after cutting hard agate, like Brazilian) and I would end up dressing it after ever 3 or 4 cuts. When I looked at the edge of the blade today it had a nice round edge. Swaging it put a square edge back on it and now it's cutting the best it has since I got the saw. You can learn how, here: home.comcast.net/~eugenemineralclub/rocksaws.pdfI started out with a pretty light touch until I learned how hard to hit it. I'm just hoping others can learn from my experience and reap some benefit. Chuck

Thanks, Don! This is my first time cutting Flint Ridge. The Brazilian agates I've cut have been pretty tough, too. I am using the slowest feed rate.
Good advice, Lee. I'm certain others will benefit from it, too.
I've solved the problem. It came down to a combination of the dull blade, the tough material, and my rebuild. My belt wasn't quite tight enough, so when the blade started getting resistance from the rock, the drive pulley started to slip. The dull blade just made it worse.
I changed the position of the motor so the belt is tighter (but not too tight), added a little belt dressing, and the saw is cutting like a champ. I wish I had swaged the blade long ago!
Thanks to you both for your help. It's people like you who make this board so great!
