In all fairness, the gentleman I bought this saw from has very valid reasons that maintenance was not done for so long, and this is absolutely no slight against him. It's just a good reminder that "out of sight, out of mind" can work against you. This is the pan of a Lortone LS14 slab saw that I bought on Saturday. It needed an oil change, as the oil was pretty dirty, so I decided to take it apart and clean the tray/pan out. Even after taking the bolts out, I had to pry the main body off of the pan. It's worth noting that the pans for the LS14 are completely flat on the inside. The variance seen in the photo is purely the impressions left by parts of the upper saw portion. And yeah, at it's deepest, it's about 2.5" thick.  I'm so glad I decided to do this. The pump will probably last a lot longer  |

My 18” looks like that full of sludge
I just use rags and a paint brush to clean it
Someday

Looks like he did grease the arbor bearings after the sludge had built up. That black goo is about where stuff would fall with the arm raised.

Robin: Possibly, but the smell of it is pretty darned toxic. I'm starting to wonder about the pan, now that it's clean, as to whether or not I should get the machine cleaned up, re-assemble it without the pan, and then completely strip all the paint etc off the pan and repaint it. The body needs it too, but I'd like to use the machine this year also. lol. The pan I can't risk having rust burn through though. Clean as I care to make it currently. Looks a LOT better.  (edit: For Sale - 1 Lowe's bucket. nearly full with rock sludge and bad oil. Sift through the sludge and see what treasures are waiting for you! $1000. Pick up Only)  |

Could that black be some kind of funky undercoating? Looks like the paint is flaking off leaving the black in some places. Paint color on the bottom of the pan looks different from the back wall on my monitor, too. The inside of the pan on ours isn't even painted.

Paint color on the bottom of the pan looks different from the back wall on my monitor, too. The inside of the pan on ours isn't even painted. I'm still leaning towards the pan having had a fire at some point. The paint on the upper portion of the machine and the back end of the pan (visible in the top picture) were distinctly black and smelled like burnt oil. Additionally, when cleaning the blackened areas the original paint peeled off effortlessly with a putty knife. That or at some point maybe one of the previous owners tried using a diesel/oil mix? I'm not sure. That toxic smell is something I remember from working on cars (couple drips of oil on an exhaust manifold are more than enough to stink the place up momentarily once the engine gets hot). Going to pick up some bolts/nuts today. A few of them came off just fine but are a little worn. I'm still up in the air on whether or not I should strip the paint off the pan. Being that the stand it came with is just a frame (the bottom of the pan is exposed), I'm very tempted to drill a hole in it and install a large drain pin. There's a lot of "could do" things, but there's an equal amount of desire to get cutting. |

Its hard to imagine any significant rust issues with the saw having oil in the pan (unless its unused holding rain water for a year or two). I have some experience with this saw, and would suspect that a drain hole in the pan would not help much in clean out. The oil is not that deep is it. There is too much of the pan that is inaccessible when the saw is in place to allow adequate clean up of sludge, grunge, and gunk, even if the liquid was gone. Its a lift it out and scrape it out task and liquid in the pan probably helps the process. If you use a pump where you can redirect the pump outflow, you could pump as much oil from the pan as possible and accomplish about as much as a drain hole. Just pondering the situation. If I ever had 5 slab saws one of them would be this beast. There are certain cuts that it does extremely well.

starting to re-assemble. I wanted to clean out really well where that switch box is, but it appears welded to the saw arm. will wipe it down a bit more, but overall I think the machine is clean enough at this point.  |

Your workshop looks immaculate. I'm jealous  . Actually, right now, my wife is parking in the driveway while I do the same thing you're doing. Looking forward to seeing the saw in action. I, too, have a five gallon Home Depot bucket filled with used oil and rock left-overs. Maybe we can get another ProBoards auction running and see if there are takers. |

Believe it or not, I consider the garage to be a disaster area right now. There are white spots all over the floor from when I was polishing that marble slab I have, and I haven't had the chance to mop or sweep it out for a few weeks. If I don't feel comfortable walking around in there barefoot, it needs to be cleaned. Obviously after doing metal work or woodwork ,etc I don't walk around without shoes, but it's a mindset. |

Before you rewire the switch in its current location, you may want to find a better/more convenient spot outside the enclosure.

Before you rewire the switch in its current location, you may want to find a better/more convenient spot outside the enclosure. I have been considering that, however the images I've posted don't show the whole set up, and currently I want to re-assemble it to how it was when I bought it before making further modifications. The previous owner installed a push button on/off switch on the very end of the arm, so when the saw drops after finishing a cut, it gets turned off automatically. I think the one part I'd like to modify the most would be a means of quickly disconnecting/reconnecting the power wire that goes from that switch box to the pump, as that specific wire ties/binds the saw arm to the base of the machine (sort of, I realize the pump isn't bolted down, but it makes it a lot more complicated to remove the saw arm if needed). The switch itself is going to get a gasket type material between the faceplate and the interior, as an extra protection against oil, but it's location is a concern. Still a long way to go before I can even test it on a rock. |

The shutoff switch is a nice touch but . . .
I usually cut four or five slabs before I shut the saw off. I clamp the rock with that in mind and wind the arm back to where I want the first cut. When the first one’s done, I lift the arm with the saw still running, crank the arm four turns for the usual 0.200” slab and ease the blade into the next cut. And same again till done.

Got the pump cleaned up. I don't know much about pumps, but it came with the modified 2liter bottle bottom which I assume was to keep mist from getting into the air portion of the motor. It was held on with small washers that made it functional, but I changed it out for a modified paint mixing cup with rubber gasket material and some oversized nuts between the plastic and the motor as stand offs so it's nice and snug without potentially breaking the plastic. The tiny thin metal blade in the base of the pump (the part that actually pushes the oil around) is not something I expected, and am very thankful that I noticed it. It's slotted such that it slides onto the drive shaft snuggly, but if you can't see it (because of rock snot, for example), and you pull the pump pieces apart, it gets detached and takes a bit of tweezers/small pliers work to get it back on. That said, it is back on and snug. Now I just need to rig up the wiring so I can safely test it and let it clean itself out before putting it back in the machine.  |
