A Powerhouse Rock Saw

 I am a member of several Facebook lapidary equipment groups and often see people dissing the Hi-Tech 10 inch saw. It's a cheap build and not powerful enough to cut big stuff- especially using water, not oil.

Well, I've got news for you guys- you're dead wrong!

Today I decided to cut a rather large rock.


I don't use a vise and that is a 10 inch Hi-Tech sintered (red) blade that I have "reconditioned" using the Highland Park technique of hitting the rim with a bastard file- works like a charm. As you can see, the rock is a full 3 5/8 inch high and while it's a little macro, it's still a silicate and plenty hard. I cut two slabs.


The first slab was 5/16 inch thick and once I saw what the saw could do, I cut the second 3/16 inch. The saw actually has a vise and a bridge whose position can be changed by using different holes in the deck but honestly, I find that I can get uniform cuts just by lining the piece up using the patterning on the deck. That's beautiful flame agate around the edge. Here's a close up lit from the front.


I will sell these in my shop as slabs to be placed in front of a light or candle so here's the back lit money shot.


One last thing about the saw: I have used it regularly for 4 years and cut a ton of rock. There has been absolutely no warping of the resin body and, of course, no rusting. It is one tough customer. The blade is as true as the day I got it and the Hi-Tech red sintered blade will go to-to-toe with any other name brand in both quality of cut and durability. Because it uses water, even my artist wife likes it and, since she makes paint from the rock sludge, she'll even clean it for me! Check out an earlier blog post to see a painting she did using the sludge.

If you ever find yourself on Digby Nech, stop by and if the weather is good, I'll fire it up for you.

    1. Looks even better in person. We have amazing agate here on the Bay of Fundy.
