Hi,

I've been restoring a farm engine and need to hone the bore before I fit
new piston rings. I have one of those three-legged deglazing hones.
Apparently these are supposed to be used in a variable speed electric
drill, but the one I have doesn't go slowly enough to produce a cross
hatch with the recommended 45 degree angles at the sides. I wondered
about trying to use a hand brace. What do people think? Also, what kind
of oil should I use for honing (I doubt it's critical, but I thought I'd
ask)?

Best wishes,

Chris

Chris,
Long ago and far away, I even cross hatched a cyl. with hand held sand
paper.
You may need coarse grit stones doing it that slow.
Then prosperity hit and I bought a 1/2 inch drill motor at a pawn shop.
Covered in cement, shorted cord, bad switch, and all.
500 rpm, i think.
Went to trans fluid from 30wt so I could see better, do it quicker, but
the oil is probably better.
Do NOT minimize the clean up afterward - lots of soap and water, trans
fluid wipes, solvent, until a paper towel comes out like new.

Suggest simply plug the trigger on and off to limit rpms while stroking the
hone up/ down is all you probly need to do.

Otherwise it will take you forever and a day with a hand bit and brace type
setup

Use a low speed 1/2" drill if you don't want your arms to drop off. Use
mineral oil as lube. It's dirt cheap and the principal component of
most high$ oils.
