Marking Blue

[JOEPRO]

Sorry to ask a dumb Q

What is the Dykem type used for? It dries so is it so you can mark something with a scribe?

Or is it an indicator for bearing contact etc? Or both.

I have the rub off can in post #1. I used it to check a small cylinder head for flatness which worked great. But for checking the contact of a drill chuck arbor can I use the same stuff? Or should it really be a trying type and see where it rubbed off?

Dykem is for marking out with a scribe, good stuff, a little slow to dry so I have the heat gun to hand to speed things up.

Fwiw Dykem is just shellac with indigo dye

These are brilliant for marking metal. Dykem's good, but takes longer to dry and is a bit more effort to spread.

Link here. It's like the big brother of a sharpie but it works better than the normal sized ones on metal. Never seems to get upset by a slightly oily surface and just keeps on going. I've had mine for years (after inheriting it from SWMBO's Dad; who knows how long he'd had it) and it just keeps on going.

Use that stuff you have.

Bit too much blue on there Joe.

Yes more than likely.

I forgot to get a before but it showed up a bad warp in the small alu head from my compressor.

I then wet sanded it flat on a porcelain tile and re checked. That was the photo that showed the blue then contacted all of the head and it was flat.

That was a tip I picked up here, worked very well

Funnily enough, we got asked for some last week. My manager looked at the guy a bit blank as he didn't know what he was on about. I stepped in. We don't sell it. BUT. I didn't know there were different types. that's useful to know.

If You put Your markers standing up with the point down You will get much greater mileage from them.

It comes in just after the longstand, tin of elbow grease etc….though I suspect HSE dept might not like coshh implications of blue ears. Works a treat on the head band of hard hats for baldy folk!
