I did not clean it before I used it. I'll check that out. In my haste and ignorance I did bring the rpms up high because it was not working good. That was over a year ago and I put the tool away in discust

1200 rpm seams to be the sweet spot for mine.

An ordinary 1/2" dowel pin works remarkably well as an edge finder. They never run perfectly true so if you look at the gap it will sort of flash as you approach an edge. When it stops "flashing" you are .250" from the edge. The only caveat is that you need good light (and eyesight) to use one.

That was my very first edge finder. I either blued the pin, or used a marks-a-lot (pre sharpie days). DP's are usually a couple of tenths under, but they run out a bit, as Tom mentioned, so for most work, it averages out.

My B&S edge finder showed up today. Seems a bit stiff so I assume it needs to be cleaned. What's the best way to clean it, just spray some brake clean in it?
RE: Edge finder - TomG - 03-03-2015
I clean mine with some solvent and then lubricate it with a drop of light oil like 3 in 1, or better yet, clock oil. You want something that isn't going to get gummy with age.

My B&S edge finder was coated in a waxy substance that's kind of tough to remove. I still don't have it all removed so I'm going try what Tom said to do.

Thanks Tom, I'll give that a go.

Acetone, which is the primary component of nail polish remover will cut most of the preservative and leave it dry and ready for a drop of precision lube.
I would encourage you to check it for accuracy before using it on anything really critical though.

Mmm - now how many of us use nail polish
