Thread: Layout Fluid

I guess an engineering supplies store may have it, but I bought a litre last year online from R S Components

Jeremy,
Thanks didn't think of R S. Wow liquid gold

Hi Mike,

I haven't tried this myself, but it's supposed to be useful for marking out on *steel*. Dissolve a little (don't ask me how much, this is real backyard chemistry) in *very* dilute sulphuric acid (diluted battery acid). Paint on cleaned bare steel, and the copper plates out as a thin film that you can easily mark.

Don't ask me where you go from there if you eventually want to get rid of the copper. I'm not a chemist.

For simple work I just use a wide-tip felt pen.

Felt tip marker works satisfactorily. Also useful for blueprinting (to refine mating parts).

I have searched fairly widely but can't find a supplier in Adelaide, but then I'm not sure who I should be asking. Ounce upona time I believe hardware stores stocked it but they look at you blankly when asked.

I guess a wide felt tip marker would be a suitable substitute.

Any advice appreciated.
Cheers Mike

Blackwoods have it in their catalogue ,made by Dy Mark and comes in a aerosol can .
I don't think it's as good as the stuff we used to mix up .(powder and metho)
I have been looking for some as well ,but also get blank looks when I ask for it, certainly can't get any here in town.

At $64.00 a litre they can shove it ,I'll stick to felt tip pens ,you can buy hundreds of them for that sort of loot.

we used to call it marking blue. *G* because it was blue. There are two types the one that dries out which is great for putting on a surface you are going to mark out on and the "soft" or "wet" one that doesn't dry and you smear over a surface before testing against a surface plate to see how flat it is.

Beaut stuff if you have a true surface if you want to see for instance how true the sole of a plane is.

Thanks everyone,
Yeh Studley many years ago bearing blue sat in my tool box not sure the apprentices have ever used it now.
If a couple of local machine shops can't help me with a small quantity I'll give Whitelaws a try, failing that sweet talk the stationary clerk at work

Cheers Mike

G'day All.
I use the Dymark layout spray. Deep Blue that is fast drying and doesn't rub off too easily.

I use Dy-Mark in a spray can.You can call 082319787 in Sth Australia,it is for use on concrete,bitumen,looks like head office is 072712222 in Qld.

Yep "marking blue" , we used to mix our own when I was an apprentice ,the place where I worked bought the powder and we had a five litre flagon that we mixed it in with metho.
It was also used for initiation ceremonies for new apprentices ,until a Mother came to work one day enquireing about her sons blue testicles.
The non drying stuff we called "bearing blue" ,used for marking the high spots on lathe beds when scraping flat. A small amount goes along way ,I still have acouple of tubes in my toolbox.

Kev.

Zeroing in on this stuff thanks to the info here

Thanks, found them they have an office not far from me. Don't have spray in stock but 250ml bottle in various colours for $5.95 that will do me

Mmmm...... brings back memories. Tried the bearing blue (tube) in some meths it's not soluable

Cheers Mike

you can get bearing blue from Repco or Auto One
