Careful using transformer oil, It used to contain PCBs (I think) anyway carcinogenic whatever it was.
I use mineral oil, I find where I am generic brand baby oil is cheaper than horse laxative. My rocks come out smelling of roses too. I filter it with a bit of flannelette shirt , though a pillowslip works just as well.

I believe it was in the 1970s. Once it was realized that those transformers were leaking toxins into the road ditches that ran into the waterways they made them start using more environmentally friendly mineral oils. So unless some old lapidary's estate still has a 50 year old drum of the old oil still sitting around it shouldn't be a concern these days. |

Hello Everyone,
My new Highland Park HT-12 was just delivered and I have it all set up, but there were very few instructions and there doesn't seem to be great information available on maintenance, care, and use.
Are there any tricks to placing rocks in the vice and securing stability?
How long does cutting oil last? How do you know when it's bad or needs to be filtered? Is a brown paper bag the best way to filter cutting oil? Where do you guys buy your petroleum free cutting oil?
How often does a saw need to be cleaned? can it sit with oil in it for en extended period of time using it to cut a couple times per day?
Cheers!
Highland Park had their own YouTube channel. I highly recommend watching their videos relevant to your piece of machinery. Also, they have a manual somewhere online for one of their saws. Prob be helpful to print it off and have it for reference |

Does anybody have any insight into how often arbor shaft bearings should be greased on slab saws? I can't seem to find any information on this...including in the owners manual.
