When a saw has metal parts, some kind of oil. Covington can probably tell you what to use. I have had good customer service from them. What I like about my trim saw is that except for the blade and arbor it's all plastic and I use water with an additive in greater concentration than for using the wheels.
If your 10 inch saw has the same autofeed as my 16 inch Covington combo saw, it has a clutch with a small motor that turns the threaded feed. The clutch is a very sophisticated design, but I hate it and I need to replace my clutch. They sent me one for free but replacing it is a project that I don't want to undertake. For what I slab a 10-12 inch saw would be about right, but I don't have enough rough to justify buying one.
I slab my rough using my 8 inch trim saw, hand feeding without a vise. You saw is better than what I have for slabbing. It has a vise.

I didn't get the saw with mine, thought mine looked pretty good at purchase, yours much better.

Any recommendations on the brand or specific blade to buy? I have nothing to base my decision on besides google searches. And so far the main thing I’ve read is botched blades tend to chip the slab at the end.... but other than that I’m pretty clueless on what brand or model is sought most often.

Stand complete!!! Just waiting on the new board to come in for the top and then I can re-assemble. Once done, heading up to Covington to get their help on adding more wheels with decent spacing. Then getting some oil for the saw. Still need to buy a blade and finish setting up the gravity feed that was put on here before. Was going to do the auto feed but after doing some research and talking to a guy at Covington the consensus seems to be that gravity feed is the way to go if done properly. any opinions on how many wheels to add? I do like having some decent spacing. Quartz posted an awesome set up but I’m not sure if I need that many on my unit. I for sure know I need an 80, 220, then from there I’m not really sure how high I need to go up and in what increments. Originally I was going to keep the sanding wheel but it seems difficult to change out papers on this unit and sanding belts seem pretty expensive for being something I’ll have to change out so I’ll probably replace it with more wheels. I don’t have a specific type of rock I work with, I kinda like doing a bit of everything and anything I come across.

Does anyone know what this piece is used for? It wasn’t attached when I bought the unit and I don’t know where it goes or what it does.

Check out this eBay listing and you'll see where it goes. www.ebay.com/itm/202580023328Looks like you have the support bar in front of the wheels mounted incorrectly. Seems your mystery piece is a hand support. ETA: that support bar is optional to use when you run the machine. Many folks probably remove it. I wouldn't use it, but I just shape rocks, don't make cabs. Heck of a deal on that machine. You are fixing it up nicely. I'd use mineral oil in your saw. You can use baby oil for now. It is just scented mineral oil. Get a couple big bottles of whatever is cheapest and your shop and your rocks will smell nice! You can get more (like in gallon jugs) at better prices as you need it down the road, but the baby oil will getcha going.

adding... from the one picture, your saw blade may be okay, just rusty. A good new blade will cost ya more than 50 bucks. I'd probably run that old one and see how it works before buying new. May need to cut some obsidian or a piece of brick to freshen the blade. Worth trying anyway, unless you just have to have shiny and new (which I would understand!).

That link was definitely a perfect picture to share, so thank you.

It looks like that square block would sit a cab preform right at the same height as the arbor shaft – call it 3 o’clock on the grinding wheels, or 9 o’clock down in Oz, whatever. : )
If so, that would make it real easy to grind a consistent 90° edge all the way around a cab. If it doesn’t sit dead nuts on the shaft center, then you’d get a consistent bevel all the way around. And If the tool rest bar isn’t symmetrical, you might be able to flip it and take your pick.
Other than all that nonsense, it looks like the bar can only interfere with grinding a cab. Bigly.

I have something like that made out of plastic for my Genie. I never used it.

Your saw probably never had a power feed but could ha e or in the future be rigged with a gravity feed.nice work but saws are supposed to get dirty and fail in beauty contests.

whoa whoa whoa!!! I just saw your thread in the cab section and rushed back here to see if you had finished your machine. I missed it when you posted this I guess. Nice freakin' job man!! It looks really sweet. New paint job, water system, wheels, blade ... GOOD WORK there. What are you going to put on the end of the shaft? $350 purchase now looks like a million bucks.well done

What is that knob looking thing on the outside of the saw oil sump/box? (left side towards the front looking at the unit)

What are you going to put on the end of the shaft? $350 purchase now looks like a million bucks.well done Thanks!!!! After spending so much time rebuilding it, I’m attached to this machine! I’m super happy with it! I’ll post a picture of what I did with the end of the shaft. Right now it is a flat polishing pad. I had leather on it but I swapped it out with felt and I’m getting better results. I also thought of sneaking in an expandable drum and using the polishing pad to hold it in place but It would push the polishing pad out enough that I think it would spray every where. I also added a light from cab king which works great! Finally the knob on the left is to control how much oil fills in from the sump. There’s two compartments in the saw tank and they are connected only by a small hole. That screw is pointed and either closes the hole or regulates how much oil the blade is sitting in. Cool design but I usually just open it most of the way cuz I’m afraid of using too little oil on the blade and ruining it.

That's a first class job you did on the machine, looks like new. P.S. I get better results using felt than leather too.
