I just received my new Starrett combo sq. I’ve never had such a nice sq before, so am wondering if I should apply wax or anything to the blade (satan finish) to preserve it’s appearance? Thanks,

I like to keep a little lube of some sort on mine, I have a jar of mineral spirits, paraffin wax and petroleum jelly that wipes on and drys well. Its my poor mans Boeshield (which is just mineral oil, wax, minieral spirits and propellant) Works the same, costs 2 bucks.

I preserve mine the same way I preserve my old handplanes: Camelia Oil.
Wax would be messy because the tight tolerances.

Keep in mind the fact that your square will often come into direct contact with your wood, and some high-tech protective formulas could interfere with finishes. Silicone has been especially singled out.

A liight coat of Johnsons Paste wax, original formula, on the exposed metal surfaces, then buffed, will keep rust away, lubricate the parts, and not affect finishes.

I think that would be “Satin finish” , as I haven’t seen any Satan finishes on anything recently ;o)

this is actually a very useful thread- thanx for starting it, I haven’t even thought of doing that to mine. touche!

I do happen to have Boeshield that I got originally for my drill press. I take it, this should also be suitable?

That is one fine tool. I’ve had one for a bit over 20 years. Still in good shape and straight,though I have lost the center finder, protractor and scriber. I use mine at work, mostly for machine work and layout, so a light spray of WD, wiped off leaving a thin film works for me. A bit of advice though, sorry if it is somewhat obsessive. It is a combination square, a measuring and layout tool, not a hammer, scraper, crowbar or screwdriver ( yes I have seen people try to use one those ways). Also if welding keep it well away from any spatter,( shuuudder). Don’t let it rattle around in a drawer with heavy tools, bits and blades. Precision instruments remain so with proper care. Besides, a proper case would make a nice project to build. If you do get a small nick in the rule it can be polished out with a fine oil stone. Take the time to do it gently and keep it square. Again, sorry if I sound a little obsessive and am restating the obvious.

I’ve had mine since the early to mid 70’s, pre 76 I can say for sure, never waxed it, never oiled it, it’s still like new, and I use it religiously. The only thing I had to do was last year replace the fastener that holds and clamps the scale in place, I wore it out…
