So my question is.....
Do you think it would be better to use water w/additive in the trim saw, or should I stay with oil?
And below is the reason why I ask.... (it's a little long winded, sorry!)
Since I had to replace the bearings in my TS-8 Trim Saw I figured I'd clean it up too. So I used engine degreaser on the inside box, let it sit for 1/2 hour, flushed it out good, Simple Greened the outside of the case and rinsed well. scraped the rust out, mostly surface rust. and sprayed the inside with Rustoleum Engine Gloss Black Paint, Gas & Oil resistant, then covered the outside in Camo Bark Gray, flat color. (as a primer type coat for an interesting paint scheme to be in another post.)
Anyways I have the bearings and was test fitting them to the saw box when I got to thinking.. with new paint I can go oil or water... I would prefer water for the Trim saw as it would be easier not having to clean the trimmed pieces before grinding, which would suggest water with an additive (the saw came with something to add to water to cool and help prevent rust in the saw, but, the operator at Lortone said I should never use water in the saw, only use oil or it will rust, which I just repaired so should be good for a while.
(A new 'box' for the saw is $95.00, which isn't really that expensive and my brother works with Aluminum so I could always have him build me a new box if needed and no rust issue there... plus wood is always an option for rebuilding!!)
I really would be interested in the why behind the answers to eally give me thought/insight to your reasons.
Thanks in advance!!

plain water will rust, but lots of rust inhibitors available
IMO pink RV antifreeze and water mix is best for 8" saw. it is what the Salem club used, and their 8" saws never rusted.

Daniel, I was reading a old posting from another lapidary site/blog about using that too.. I have to find it as don't know if it would be at the local parts store or an RV shop only. Thanx for you input!!

I had always used Kerosene mixed with a Mineral Oil. A mixture which is good for lubricating, but not so good as a coolant.
Now I use water with a rust inhibitor, it being good for cooling and is much better for clearing any debris from the saw cut. If you can do these two things the lubrication is of a secondary importance.
Have you ever been into a machine shop and seen a rusty lathe or milling machine, they use suds, a mixture of water and rust inhibitor.
Regards,
Derek

Plain water and drain after use would work. Or, a water based coolant. I would drain and save mixture after use here as the water evaporates too fast. Any saw manufacturer will tell you oil only if it is a metal saw. Rust is one issue. Bearings especially the bearing exposed to tank will last longer with oil. Lortone doesn't use any cast iron parts but they really rust. Oil cools better too so longer blade life. Depends a lot on what you are cutting.

You can find the pink RV antifreeze at Wal-Mart, especially at this time of the year.

FWIW, I just use mineral oil in my 10" saw that I purchase when it's on sale at the local pharmacy or grocery store. That's primarily because the agates that I cut are extremely hard, the blade gets quite warm, and I have to dress the blade every three or four cuts. I also cut a lot of obsidian which isn't nearly as hard and would probably be fine with water but since I started with oil, I'll just stay with it. I guess I'm getting long-winded and saying "what John said - it depends upon what you're cutting" . Also, the prior owner of my 10" saw originally used water and there appeared to be a lot of corrosion/rust on the interior which had to be cleaned off. I figured using and staying with oil would be simpler and preventative, if messy - as you mentioned.

I use the genie trim saw attachment. Eloxite had a promotion, so the saw was $35 when you bought a genie. It's all plastic or aluminum, except the blade and the nut holds the blade in place. I use an ounce or so of kool lube and water. I've had the saw for ten years. I go through blades faster than I would like, probably from cutting too fast and cutting small rough. I dry of the blade when I'm done cutting. The blades last longer when I only use it as atrim saw.

I don't think the question was oil or water - which has been discussed endlessly here, but rather which for an 8" trimsaw.
I just think oil is not worth the mess on saws smaller than 10", and I have seen 8" and 6" Lortone trim saws running perfectly with pink water.

I would agree that water with a rust inhibitor is fine for 8 inch and under, especially with sintered edge blades. I don't recomend water with cheap crimped edge blades, for that matter I don't recomend even buying crimped blades at all.

You're right Daniel, the topic got a little off as the discussion wound through, but it was not unexpected, this is a fairly "Hot" Topic!! I thank everyone who commented for their opinions, and I have read each & everyone with interest... I read about the why's more than the answers, if that makes sense. basically anyone can give an answer, whether it's right, wrong, or indifferent... but ask them to explain their answer and the room gets quieter!! Thanx again people!! ************************UPDATE************************ Went to Walmart today and got 2 gallons of RV & Marine Anti-Freeze for $2.98/Gal each plus tax... wish I could do so well with Oil for my 18 inch!!! Now to install those pesky bearings!!!
