I spoke to the boss at our lapidary class. He has decades of knowledge that I am gaining in bits and fits. He advises that my "new" 18" Frantom saw. It has hydraulic feed and I thought perhaps my friends would like to see the feed components. He states that these machines with feeds were sold factory new from the first buyer of the company "Contempo". And some machines were retrofitted. I think mine was original... Time will tell. Here we go! #1  #2  IMG 20170704 152508385 HDR:  #3  #4  #5  #6  Feel free to ask for more views. quartzRockoonzjamespTommyaDave |

That's neat stuff Scott @shotgunner . What's the container? Is it hydraulic fluid as opposed to there being a tank?

Hard to beat the hydraulics. Sweet, last longer than us.

That's a nice, simple, and accessible system, I like that. I did a feed works ohaul on a hyd. feed saw several years ago, don't remember the brand, but it had a Ford engine oil pump driven by a 1/4", 1/4 drive socket, buried in a plumbers nightmare.

IMHO it makes no sense to put a hydraulic system on a rock saw. Rock saws are one of the dirtiest machines on the planet and a hydraulic system needs to be kept super clean. The open bucket about gave me a heart attack because it should be a closed system except for a tiny air vent on a one way system. I am going to let it go this time Scott but by next inspection I want to see these discrepancies taken care of. Jim Brown Aircraft Hydraulics Tech Grumman A6A (last I saw, still flying) VMA (AW) 225 USMC Air Wing And a bunch of other nonsense.  |

Know what I mean ? Wiper seals on the hydraulic cylinder shafts. Sealed oil system with filtered vents. I always thought hydraulics were for get down and dirty applications Jim. Granted, aircraft is pristine application. You can pretty much stick in/out lines to a hydraulic pump and submerse it in mud all day long. Just keep the oil clean and the dirt out of the oil side of the system. Guess I have been on a backhoe one too many times. Never knew you were a Marine. Dad was a Navy fighter pilot. Flew F8 Crusaders. Crazy man. Mr. Clean, never liked my dirty ways lol. A6A and F8 are both flown off aircraft carriers. Dad preferred the old prop Corsair. Said it was super nimble stunt machine. The F8 was finicky and tricky to fly. High skill. He flew off USS Coral. Had his canopy knocked off during a mid-air refuel, managed to land it safe. Not easy in a fast flying F8. Navy thankful but it ruptured both ear drums. |

Maybe Scott will buy a real tank. Northern.

ETA I relooked at the pics. The bucket holds a gallon bottle of transmission fluid. That bottle has a very small mouth to keep the fluid clean(ish). |

I am glad you picked up on the tongue in cheek jamesp. The last one didn't so I tried swearing off of doing that but oops, it's who I am. I have been around dirty hydraulics also NEVER AN OPEN BUCKET haha. Grew up on a farm and after I exited the military I worked at a John Deere ag. equipment dealership. Some farmers have no concept of what clean hydraulics means. I have seen the inside of hydraulic cylinders with huge gouges full length so bad that they could not be repaired. Same thing on the external shafts. Me: Sir, did you somehow get some dirt into the tank? farmer: Well, the cap was lost for a while so I had a rag in the hole. Got lucky though, I found the cap where I had been plowing and put it back on. Didn't have the nads to ask him if he cleaned the cap before he put it back on. Hydraulics are great when they are working but can really suck when they are not. Spent much more time trouble shooting than repairing. Miles of tubing in an aircraft. Jim |

Jim Of all ALL systems, troubleshooting hydraulics is the worst. The valve logic never was easy. Uh, never. Nothing angrier than a hydraulics man who found out the operator was slacking on keeping the fluid clean. A drawing of nightmares. can you decipher this stuff ? Hat's off to ya if you can.  |

Is that the same system Diamond Pacific uses on their saws? They bought Contempo Lapidary. Semper Fi Jim. I joined the Air Force because the Boy Scouts got a little too rough for me. I was a Huey mechanic so worked on clean hydraulics systems too.

If it is any bonus my tractor is 55 years old and has clear clean hydraulic oil. replaceable 2 stage filters.
Backhoe is 40 years old and oil in same condition. Also a full flow filter.

johnjsgems, How many pink T-shirts did you have? My answer to that is "all of them" jamesp, I can still pick up on about half of it but remembering the symbols is the toughest. Some I can figure out by the way and how many oil lines go to them. For instance at the very top I believe there are three double action cylinders because there is a pressure line going to each end but I do not know what the other hardware attached to them is. Lower left where it says pump 1 and pump 2, those are pumps. If you go straight right from them there is a cleaning device called a magnet to grab circulating steel. Below each cylinder there is a valve but I did not trace the lines to try to figure out which way they work. There are pressure reducers, check valves and pop off valves all over the place but I do not remember which is which. Second from far right are some kind of electric shut off or safety valve. Trivia that most people will argue about is "a hydraulic pump does not create pressure". You can run a bazillion gallons of oil through a pump without having any significant pressure. But, if you put a restriction or a plug/valve in the line you will get pressure. Jim

It is the troubleshooting that is so difficult when several valves are involved. OK if you have dozens of pressure gauges tapped in Lol. yep. Shut the valve off and dead head a gear pump and you can rest assured the pressure go straight off the chart. |

I missed out on pink tee shirts but served at a time you could not wear a uniform to town (except near the base) and met with hostility if anyone suspected you were in the military. I was proud to serve in air rescue anyway.
