Honing cylinders; Oil type
Topic Started: Mar 4 2013, 03:49 AM (982 Views)

I have access to an oil called Tap-magic. I would like to use this in conjunction with a berry hone for my rebuild. Is this oil acceptable or not? I was originally going to use WD-40.

While I've not used Tap-magic it show as a cutting oil when I look it up, it should wold fine as will most any thin oil. Good Luck!

tap-magic is for use when cutting threads. it flashes off really quickly to cool the metal as the threads are cut.

i don't think that it will be a very good lube for honing cylinders as it won't stay in the bores. it will evaporate very quickly. i'd use 3-in-one or sewing machine oil.

Edit: Short answer is yes the tapping fluid is ok. The reason why is in the Flexhone article. Follow the link for their take on honing fluids.

Actually, it is. It's diluted by solvent like a lot of oils, but it is about 35% oil.

I always thought that WD-40 had a fish oil base. Hmmmm.
Thanks for the comments. I'll try the tap magic and if it does not work to my liking I'll switch to a light oil.

Best way to determine what is in products like WD 40 is to do a search for the MSDS sheet. It includes CAS numbers for all the ingredients, or possible ingredients. Do another search for each of those CAS numbers and you will have a pretty good idea what is in it.

In this case WD 40 contains 30-35% petroleum based oils. There are a number of possible types of oils but each has a CAS number and can be identified by that.

Your suppose to use oil when honing? Uh-oh, guess I better tear down my engine block and add some oil, because when I honed it four years ago, I didn't use oil. Hit it with a hone in dry cylinders. Its lasted this long, should be good for another 100K, huh?

Yep.

My chiltons didn't say I needed to apply oil. Or maybe there was an oil stain on that particular paragraph of that POS, worthless, useless repair manual. :die
