Nice. I got to get around to cutting the rainbow obsidian that just showed up. I'm having problems figuring out the flow lines, some you can see many you can't. I guess hack and end off and if nothing try the other? We'll find out I guess.

QE-3

There's already secretly been QE3, but they'll still call it that if/when it happens. I'm pretty sure people would be up in arms if the non-Federal reserve would really let us see their books.

Vinegar works too, I have some parts soaking right now. Be careful with it though, i've heard maybe it's not the best for moving parts but I haven't had a problem yet. Really weird, all the rust foams to the top. I usually leave stuff in it 1-2 weeks. I think it would be ok on shrouds etc but like I said i've heard corrosion issues with moving parts so be careful.

Yep it's huge and fully functional and supposed to be in good shape. Just one problem--getting it moved. I have some phone calls to make.

BTW it did cut all the rocks in this thread and some of those slabs are nearly 8" across so I can't complain too much considering it cost me about $250 to build but I already had a motor. Granted i've seen used machines for not much more which would be a better route for most people but I like to build things, that's part of my hobby also. Here is a handbuilt wood/metal lathe that was built in the 1920's by a master carpenter who may be a distant relative of mine(not sure yet but checking) and utilizes parts from a Model T. I am going to use this for metal spinning among other things: And here's something im going to go look at and potentially buy:

Hi Lee, yeah those are thoughts i've had. Once you build something it always seem you come up with another idea lol. I forgot to mention to the other post that there's another set of shaft collars not in the pic that you can adjust for slab thickness.
For now you hold the rock above the blade by holding the string that is attached to the counterweight and slowly lower it until the kerf starts then you can let go.
The handle would be a good idea but just pushing down on the weight bucket isn't as inconvenient as it sounds. Of course you could also make a regular crossfeed instead of using shaft collars.
I didn't want to get too involved on the first time go around so I could see for myself how things would work and then tinker with it. In other words........I didn't want want to spend too much time building something that turned out not to be worth the effort. As it is I only have 3 days in it and now I can play around with it. It's cutting fair. Truthfully I built this because I was just curious how it would work lol.

Just fyi I wouldn't advise slowing your 4rpm motor down, it will be too slow. I understand you think it might not be powerful enough, if it isn't a saw cutting 2" per hour wouldn't be a good trade off. I don't care to figure it out at the moment I drank too much beer last night but if you know the number of threads per inch of your drive rod and the gearmotor rpm you can figure out the rate of cut.

Always kinda odd people will shell out that much or more for a smaller saw. I found one like that in my local area they want $1500 I offered half that.
The main reason it's not bid on is it's a pickup item only. I have a frieght acct and have sold a lot of stuff like that it's not that difficult and they prob could get considerably more by cleaning it up and crating it but some people just don't want to deal with it and that's understandable.

If your gearmotor doesn't work for around $50 you can order them from www.mcmaster.com/. I've seen them push rocks on a 36" saw. Of course they were vises on wheels not metal to metal shafts. Oh and btw.........last time I looked at a Lortone saw there was no slip clutch that I recall. You can get by without one just don't run off and leave your saw alone.

Yes, a larger pulley than what's on the motor slows it down and increases power. Think go-kart.
As far as slip clutches go i've built them with lock washers pushing up against larger flat washers, Steve Covington told me how to do it but hard to explain.
It depends on how unforgiving your nut that drives the vise is. Will it slip, or bind? You can test it by block the carriage with something other than your blade. But don't get mad at me if it screws up your threads lol which it might do if it's a really powerful grip.
I have 2 ideas, one I used which is just a springed metal clamp that I weld a nut in it then cut it in half. I don't think it has enough grip to bind a blade but it will drive a vise. The other is from an old Mojave saw I seen. The gearmotor wasn't mounted to the saw box just the threaded shaft. It had a arm mounted on the gearmotor which went to a switch. If the vise binded the gearmotor would start floating upwards and that arm would flip the switch off.

Sure Borock, there's really nothing to it. I will say getting this saw into alignment has been a real pain. I finally got it, I probably spent more time tweaking that than building it. You'd think clamping rocks in this would be hard, I use a board to hold the swing arm up and it's really not that difficult.

A lot of people don't look at the bigger picture. It's all Obamas fault(which by the I hate him and Romney) and many have already forgot what Bush did. Not to mention, the 2008 crash wasn't caused from anything overnight it was the culmination of decade after decade of idiots abusing power. Spending went crazy under Obama to avoid a complete collapse of the system. Unfort the same problems are still here and have only been papered over. Nothing structural has changed. Now true it does seem at first glance the dems are for the working class and poor...........but no one bothers to remember that Clinton signed in NAFTA and Obama thinks more of the same is good? That's why I am bailing on this sytem. This gov't has an agenda with a bunch of richy rich puppets all trying to be in power and one group will screw us in ways the other won't and everything points to the same end goal. Which I don't care to speculate, or even say there is an end goal as in history every civilization has gone down this same path. There's all kinds of opinions, maybe all this bullet discussions need a new direction such as there's gona be a lot of pissed off muslims in the US if we blow up Iran perhaps the bullets aren't for us afterall. There's just no telling till it's here and I know it sounds bad but im getting tired of waiting. To me it's just been too damn quiet. Maybe it's the paranoi from living in an isolated country setting of course it's quiet lol.

Regarding the unfunded liabilities comments............politicians will say anything to get into office. A lot of them get to where they are making promises they know they can't keep......but people believe it's true. For example.......Obama said he was gona bring home the troops. Instead we have engaged in more wars and they are just chomping at the bit for Iran. The US economy can make it on $4 gallon gas how about $8? Of course there are those that say we will obliterate Iran in 2 weeks and it will be short lived so time will tell. That's of course if another major player doesn't get involved. I truly believe we are being led by a bunch of crazies. Oh and back to the original subject............Romney says he will create 12 million jobs. A ridiculous statement and just what everyone wants to hear.
It's so much more fun to talk about rocks lol.

Personally im thru with red vs. blue and have decades of proof to back me up.
Most of our politicians are filthy rich and are just there to fill their money bags as many times as possible at our expense.
I could go on and on, but long story short with a few million discussions like this daily posted openly on the net (and many much more violent) it's easy to see why the gov't is doing things like NDAA, 30k drones etc.
A lot of people seem to think that if there's a collapse that means the gov't just goes away. LOL. I wish that were true but that's when the real draconian protection measures come into play such as you'll be going to jail if you don't return all the gold you bought and other idiotic measures.
It's coming, and don't blame the bankers blame their enabler: The Federal Reserve. Which still blows my mind the number of people that don't know that the FR is a private entity and there's nothing gov't about it except they control the gov't.
Then we have the largest blackhole in the universe........WallStreet. Which btw would be at ZERO right now the only thing holding it up is trillions in digitally created zero's transferred to big banks who pump this overpriced garbage up and congrats...........all this is being transferred to the treasury which means you and I own it.
Oh well, I don't have bunchs of gold but maybe a few diehard rockhounds would barter for rough lmao.

BTW.........one good thing about is when rockhounds have boards like this just about EVERYONE knows what's up. It's my theory that the internet has been a dangerous 'awakening' device and the elites are in hurry up mode and the ground beneath them is falling apart faster than they can implement operation global gobble, or OGG as I refer to it. I'll stop there for now.
