In my shop yes, the answer is no. On an 8" saw, I occasionally feel an oil droplet on my face but the shield on the front catches 95% of the oil from the blade not actually confined to the saw table, and whatever goes laterally is trivial enough to not cause a mess (i.e. my attention). I do try to avoid wearing real glasses because oil mist and perhaps rock particles do hit my glasses and result in scratches if I don't rinse them carefully before wiping them, but its really trivial. I admit that I'm not doing major slabbing on that saw, but your experience should be the same with compensation for longer cutting times and perhaps rounded rock surfaces.

Two of my saws have a bit of an old tshirt hanging from the splash guard. Easy to trim to direct the drip. Slabs from my big saws drain on the trim saw before the oil dry; stuff from the trim saw ( also oil) go to drain on the slab saw. It would be easy to arrange a funnel for pieces to drain into. My dad worked in a garage during the depression and all of the oil he used in his car was the drips from oil that would have otherwise been thrown away as residue in cans bought by others.

Or heat from the propane. That's how many folks break loose frozen metal components. There is no gear puller in civilian hands big enough for what I envision you are working with. Good luck with heat.

Nice to see commitment and creativity combined. I'm impressed and pleased to not the cooperation among team members. That irreplaceable.

Ironically almost all rocks are old in relative terms and being stored in someone's garage for 30 years does not enhance them. It may mean they didn't have to dig as deep or carry them so far to get back to the car. Just saying.

My 8" Highland Park machine has a couple of polishing disks which needed refurbishing and I took a chance on a garage sale wool hat to create a wool pad as an experiment. I cut the sweat band out to allow stretching, and then forced the disk (already covered with a dense foam pad) into the crown of the had. I used hair conditioner to facilitate stretching the wool, soaking it for about 30 minutes in water. The rest is history depicted in the photos. I've always heard that chrome oxide works best on leather, but cerium oxide needs to be wetter and on felt/wool. I need to experiment with this wool pad.

The overall color pattern of number two looks like a lot of the stones that I call mushroom rhyolite, but thats just a handy title without much street cred. It can produce wonderful patterns but sometimes insists on staying with a matt finish and even undercutting those white orbs.

I think that stone looks sort of neat.

When I built my shop I install a powerful attic exhaust fan in the roof, even tho I don't have an attic. It can clear the air when it appears to be misty, but I don't use it often. A clear face mask will keep a lot of the mist off of your face, but they do get a film that obstructs vision so I tend to just wear my old glasses or safety goggles over my glasses and probably breath a bit of oil mist (however, most of my big cutting is done under cover with the larger saws, so I'm not exposed as much as I would be if this was my primary sawing outlet. Before covid hit, I bought a bargain case of n-95 mask through our habitat for humanity restore, but careful reading of the mask spec disclosed that while they were good for many particulates and medical situations, they were not officially suited for oil (I suspect they might clog up with oil and fail that way and not necessarily let oil pass through). So the word is read the specs on the mask you choose to trust. Many shields of the front of trims saws are transparent plastics, but no one I know looks through they, but instead looks over them. They get grunged pretty quickly so they are not good windows to the work surface. I hope the reduced oil level works for you. The saw is not meant to be messy.

I'm going to bet that you are using way too much oil in your system. You want just enough oil (perhaps 1/4" on the bottom of the blade) to result in a line of oil being thrown in front of the blade, but not significantly up on the vertical shield you built there. You clearly want oil to reach your cut and probably even want it dripping off of the front edge of the splash guard over the blade, but no way should you be indulging in oil splatter like you are describing. I have a simple 8" trim saw (no cover) in which I run oil, and yes I wear a shop apron and try to not wear my good glasses, but dont get oil on everything even when cutting multiple rocks. I'll admit that oil spray is more common when you are cutting slabs from round rocks as opposed to trimming slabs. When the oil hits a surface that is not parallel or perpendicular to its trajectory it goes shooting off to the side and up into the air, but thats still controlable with strategically placed shields. Try lowering your oil and see what results you get.

If you are a cook and your friend is a musician, you don't give him/her a violin or a cd, (they already have what they want and like), you know food and you give them a cook book or a nice meal. You gift from your strengths not to your recipient's expertise. I can pick a beautiful rock, and they can gift a wonderful something that they know about and understand how to buy and present. Yes, I gift rocks and feel that I have introduced hundreds of folks to a view of the earth that they had little appreciation of previously. A rock is forever, even if you lose it, maybe someone will find it in a hundred years and it will still shine and be appreciated.

Looks great. A simple lip, or ledge on the bottom piece would keep the vertical shield from spreading laterally and allow it to lift when you lift the saw table to empty the pan or clean it. That is if the shield was fastened to the edge of the table, or if you just have it clipped on the edge of the table and can lift the shield away to lift the table, it would be a functional and efficient system. I worked enough around old time farmers who suffered lost digits and more from unguarded vbelts or chains on farm machinery. I have a great respect for rotating machinery parts.

Its a great system. There's nothing like those wide wheels with multiple options on belts. I work on a machine like that when I have a real problem with midcrown scratches or odd shapes needing a soft wheel even though I have other options. Considering the array of belts offered, I think your price is reasonable. I hope you find a good home for the system.

Peruano I had just about decided on the 4-5 “ hi tech and I saw you thought it was underpowered. What did you mean by that? I was hoping to use it to cut shapes from slabs that I have cut. I thought the fact that it had an adjustable speed was a plus (I don’t really know why having an adjustable speed is a plus?). It looked easy to clean. Under powered means the saw can be bogged down if fed to fast or not using a good blade. Basically it means going slower of feeding the material and listening to the sound. If the motor is slowed by the cut, it is working beyond capacity and could be damaged. That said many folks do fine with it, but when you are used to a stronger saw, it seems relevant to consider. Many saws are a pain to drain and clean. The Rock Rascal being one of these. Some you can just drain and allow them to dry if using water. The HiTech is easy to dump and wipe out. It is a matter of trade-offs and priorities.

Once in hand and operational, a slab saw is a window through which to marvel at things. Each slice is a new look, and there's always hope for an even prettier, bigger, brighter slab or one without fractures. Enjoy the ride.

Your lighting may cause the response to bias, but the first orientation (red up) says beautiful to me. Candidly, the red down looks like sedimentation.
