I really am starting to understand why the ole timers built their own equipment. I have yet to buy a piece of equipment that had any life to it. I'm venting for sure tonight was the last straw. I have an Inland all in one, purchased 2 yrs ago never used until this week. Motor makes weird sounds after using the trim saw now and goes on and off. paid good money for that, hope they will replace motor. Bought a Covington 18 slab saw new paid big money for it, first the auto feed motor went out, replaced no charge, then the main bearing went out due to bad design,but billed me, blade stopped cutting after maybe 100 cuts bought new blade, rock jams now as it feeds now faster than it can cut....not working at the moment. Bought a huge tumbler had it a year did 2 complete cycles, barrel wore out and the neck of it fell off....not working at the moment. I try and buy American made but i'm not sure the quality is any better if not less....goes to say want something done right ,do it yourself..I would be interested in hearing about some good lapidary equipment and I don't care if it made on the moon..

your tumbler must be an MJR tumblerNot only do they fail too fast, the company that makes them will not honor any sort of warranty, nor even offer assistance on how to fix the problems. Based on my link they seem to have left the garbage tumbler biz and now sell mostly grit.

My Covington 18" doesn't have a feed motor, it has a feed system that is run off the main motor with a dubious clutch system. You can set the clutch system to slip so it doesn't feed too fast but it is hard to get it adjusted right. Not a good design as far as I am concerned but once I got it set right it seems to work OK.

I think Inland is not the best US company to use as an indication of what American companies produce. As far as the other companies I think they all make some great products and some maybe not so great. Covington saws are maybe not the best but their Maxi Laps and arbors are pretty bullet proof. Their cab machines too although they are a trip back in time. Diamond Pacific's cab machines are great but I'm not particularly crazy about their saws. Barranca's equipment is a mix of Star Diamond old technology and new and improved offerings. They are always developing new products and designed and tested by an actual lapidarist. Their price hikes Oct 1st puts a lot of their equipment up in the Diamond Pacific price range. You can always find old HP, Frantom, Star Diamond, and other vintage equipment and refurb and convert to diamond technology.

Deserthound: *L* I'm with ya on this one. It's almost like many machinery manufacturers don't even understand how the equipment is used. I've discussed my experience with my Covingtion 10" saw at length here before. My shop used to look like a graveyard of broken Lortone crap and dead minisonics. Had like four tumblers, a vibe flat lap and a drop saw, all garbage. Actually got so angry with the Lortone drop saw that I physically took it out in the drive and beat the living snot out of it with a sledge hammer. ( I have a temper!) I actually felt a lot better afterward. The vibe lap wore out it's bearings or some crap in a few weeks. Had it fixed and wore out again just as fast. Used trays for planter trays for a few years and that was the only damn thing they worked for.
Funny, but my MJR tumbler base ( I run barrels from all my dead piece o crap Lortones) has been running like 24/7 for like six years now. Won't turn a heavy load anymore but works OK for 15 pounders. Wore through a drive shaft when a bearing seized up when I first got it but the seller sent me new replacements. Now he never responds even to requests to buy new belts but it is my favorite tumbler ever. I also love my UV-10 which has served very well.
Best saw I ever had was an old used Beacon Star. Only cost a couple of hundred bucks, lasted fifteen years and was a great rig......Mel

Yep, as John so politely said, Inland products suck, like pretty much any product that claims to be able to do more than one thing. And comes encased in plastic, rocks are way too hard for plastic tools. I would set up your inland in the spindle grinder mode and just use it for that as long as it lasts. For a trim saw there's lots of options but my choice would be Polaris www.polaristool.com/catalog/item.php?unid=4633&prodpa=0A tumbler would have to come from Lortone or Thumlers. For cab grinders the best are refurbished older gear IMO, if you want new and looking for the best value I would go with stainless Lortone arbors. I prefer 2 wheel arbors so allow plenty of room to work larger pieces, but if your shop space is limited a 4 or 6 wheel unit is available. www.lortone.com/arbor.htmlOr the ultimate made in USA cabber IMO... sphereproducts.com/cabmaking-slabpolishing.htmLee

@shotgunner Rod does a lot of NW shows, furthest south will be Klamath Falls in march. We have his bead drilling vices and other inventions. If I made spheres I would probably get his cups.

Oh did I forget to tell about the sphere machine I bought, you guessed it cups fell apart after1/ 2 hours. I used a pool ball to set it up correctly, worked great . Put a rock in it, holy crap, you gotta get that thing pretty round before you start. maybe my mistake, but there were a few other design problems that had to be fixed just to do the pool ball. Not working at the moment. so sounds like a good connection for cups would be rod. thank you

There is no doubt in my mind that any mechanically inclined person with a little ingenuity, a well equipped shop, and unlimited spare time can manufacture lapidary equipment as good or better than anything on today's market. But most folks don't have access to a well equipped machining shop, or that kind of spare time. And new lapidary equipment has really gotten expensive. Especially if used as a hobby. In my opinion the best values in cabbing and slabbing equipment, without sacrificing quality, are to be found in the older, lightly used or well maintained equipment. The Inland All-In-One may be fine for the occasional hobbyist or for cutting soft materials, but not for cutting lots of large cabs of hard materials. If you like and want to stick with a flat lap, the old B&I Gem Makers were the Iron Maiden, or in this case the Aluminum Maiden of flat laps. They were made in both a 6" and a 10" sizes with aluminum housings and bronze sleeve bearings that will not rust. I still use a B&I for my final polishing unit when polishing with messy oxides. The 10" size used a 10" trim saw blade but came with 8" laps. They are belt driven and can be powered by any general purpose 1/3hp 1725 rpm electric motor. And best of all they are inexpensive. Sears sold these units out of their catalog for over 20 years. And since they are nearly indestructible, there are literally thousands of them still out there that can be picked up on eBay , Craigslist and at estate sales really cheap. The B&I units are great flat laps for cutting cabs but the trim saw function stinks. You'd need a separate trim saw. The old 6" Rock Rascal model "J" trim saw is a good companion to the B&I Flat Lap and they too are plentiful and inexpensive on the secondary market. But if you do a lot of cabbing you're probably going to want to get an outfit with vertically mounted wheels. As John mentioned the old Highland Park, Frantom and Star Diamond units are all good to refurbish and convert to diamond tech. I would also add to that list Poly Arbor. But be careful not to pay too much for one of these units that still has Silicon Carbide wheels on it. A lot of eBay and Craigslist sellers who inherited daddy's rock collection don't realize the difference and try to price their old SC equipped units based on the prices of the new diamond equipped units and their is a huge difference between the two. As for larger Slab Saws, again the old Highland Park and Frantom brands were great. And even the older pre-1980 Lortone and some of the older model Covington saws were good. But in my opinion the newer production ones are not so good. To me it doesn't make sense to spend $2K on a new cabbing machine when you can find a good used lapidary arbor and outfit it with brand new diamond wheels for under $1K and still have $1K+ left over to put towards a good saw or some really cool cutting rough!

I have an older, 25+ yrs old, Lortone 18" saw, have had it for 3 years now and still has blade that came with it and still running strong!! Have a older 10 inch trim saw that needs rebuilding, but other than that runs good, guy I got it from put a crap motor on it and it is ready to die so when I rebuild it I will get a better motor for it. My old QT66 runs great too but as it is also older when you unplug it then plug it back in the barrels reverse spin direction if you don't watch... not that it makes a diffeence when tumbling, at least not that I noticed, still it runs strong... bought a Eastwood vibe tumbler... lasted about 4 months and broke down 3 times, then burned through a bowl and elongated the holes or the spare, now it just sits there waiting for me to get some spare cash for a new bowl so I can try again!! the older stuff is definitely better and is still out there to be had... just gotta find it!!!
Good Luck with it !!

NO! Buy old and rebuild them. Even then the bearing you get are made in Korea and last about 6 months. Covington is trying, but still lacking. Just part of the price you pay to see inside of a rock. To be fair they do go through a lot of abuse.

Motor starting backwards (usually by spinning it by hand backwards while starting) was our non-technical way of diagnosing a bad start winding. I would be prepared to buy a new motor.

i have learned that it is best to buy old stuff and fix it up to use the new stuff almost always has china made stuff it or whole and they suck at building anything besides even if you replace almost everything in a old saw you still get a better and cheaper saw than you can buy

It's also a sign of a motor that does not have a polarized plug!! OLD STUFF ROCKS !!! LOL!! But seriously, the tumbler is over 22 yrs old and has been run continuously for as long as 2 months at a time with no problems. I even went out and bought a lil cheapie desk fan to blow on it to keep the motor cooler during those Florida summers!! Also, I research the bearings I buy... I get either American made or German Made!! both generally higher grade... ie.. more expensive!!

I love my Lortone C200. I overload the barrels, but it has the same motor as the C300, so I figure I'm okay. I've run it 24/7 for about 13 or 14 months over the last two years and nary a problem...
