When Barranca was still repairing their notched rim blades they had many customers with Diamond Pacific hydraulic feed saws and Lortone saws. The hydraulic feed was not the culprit so much as owners trying to feed too fast against dull blades. Same issue with the "fastest cutting saws" from Lortone.

An exp cutter could probably handle dressing a blade and know when to do it.......feel sorry for the newbie. Hell.....let's just make a saw that cuts 100" per hour lol.

The inexperienced have a tendency to push harder when a saw starts to cut slower due to dull or glazed blade. With gravity or drop saws you hear "I added more weight but it still won't cut". I have not talked to enough people with hydraulic feed but did hear about the number of dished or otherwise blades from DP saws from Barranca.

I love the sound of an 18 inch blade cutting slowly thru a jaw full of hard agate. With a tiny 1/2 HP motor. I know that things are lined up when i can turn the saw off with a 6" x 10" agate almost all the way thru the cut and turn it back on and starts up effortlessly. I knew of a 24 inch HP that had many years on the blade. The owner always cut slow.

I have a 18 inch hydraulic, or actually air over oil pneumatic. Air from a compressor moves the carriage forward and oil in the back half of the ram keeps it from bouncing, has a flow control to set maximum speed. I run mine at 35psi, J2B2 down in Albany OR uses all hydraulics and runs the same size rams at 50-60psi.
It will be for sale soon when I get my FranTom 18 up and running.

I knew of a 24 inch HP that had many years on the blade. The owner always cut slow. Pretty sure the 18HP I just came home with has the original blade on it. The previous owner had it set on its slowest speed. Still pretty fast though at close to 9-10" hour it seems ill have to time it again and see.

Rob, my Covington is light weight but really has tore up some big coral chunks. Rarely do i cut less than 4-5 inch chunk and it is hard. Many many of them. And my 90 year old mentor cut bigger ones w/HP 24 and i think he had that blade 25 years and had a rock shop longer than that cutting his own jewels and very active w/his saw. He sold and had twenty 55 drums full of coral slabs. So i believe what slow means. And clean oil is big too. I wish my covington had a easy to clean sump right under the blade. I already tilt my saw to the blade side to keep a deep pool under the blade for cleaner oil presentation. Of course i like my kerosene/motor oil mix due to it's efficient lubrication.

I like Covingtons, some not so much but as far as the slab saws yes. I've heard complaints but they appear to be well built esp 18" and larger. Heard complaints elsewhere too but after seeing them in person I don't think I would have a problem owning one and still get the satisfaction of US made.
Been raining out this am, trying to get off my ass and go install the new furnace in my shop. Well, it's 10yo furnace but it only has 1 year use. Pretty sure it will be mounted in the air somewhere. Maybe use those set of skyhooks I have lol.

RE: the sound of the cut.
Wifey has come to like the sound of the "scratching" noise made by the blade as it passes through the stones. She'll even remind me if she knows I am cutting but the "scratching" has stopped. Love that!

Maybe i should move the saw where it would put mine in a deep sleep.

I pulled a wall mount heat pump up to the second floor with a pulley and a pickup truck. One of these tankers.

Speaking of which sometime this winter I need to build that homemade elevator so I can still see the upstairs when im older unlike the old couple down the road that haven't been up there in 15 years. Guess i'm still half asleep not sure how all this subject got encircled in your quote lol. I'd probably still be in bed had I not had a nightmare of getting arrested at the bar because I couldn't pay a $2100 bar tab.

THAT is a nightmare.LOL.
I think it's called wondering thread. It was your thread so i think i was following your thoughts about mounting a heater up high??? Does that sound familiar? Gravity feeds or heaters-i'm easy.

She is gonna be pissed when she gets home and see this shit pile. Maybe some stronger whiskey is in order.
