Rob's work is so amazing

that I have to take a courage pill before I dare post my simple stuff!

I second that, Pete....

Thanks Joe , Pete and Steve

I need a valve to control the air flow , so I decided to make a butterfly valve

The valve body so far. Machined from a bit mystery steel .

Setting the flat in the correct orientation with the PCD of the slots .

Body done

And a couple of BRASS bushes (not to be confused with Bronzes as that's quite different

) for the spindle were machined up and pressed into the body .

I Nickel plated the valve body to give it some corrosion resistances

I am sure it works the same Neo

Decided to do something different today , so I etched up some name plates to go on the forge and blower , smaller two are to go on some tooling I have made .

Undecided on weather or not to add a colour infill

Etched... how.. when does these etching, plating and all around goodie things come in a project log - more like tutorial ??

Very nice Rob, even by your normally excellent standard - you must tell more

Rob, your'e really blurring the line for us between praise and expletives!

Rob

I'm running out of things to say. I think a nice bright background colour would be nice. Pick a colour and make it you.

Cheers

Hi Rob , came out really nice, you might as well try one with the inlay , British racing Green maybe ?? or deep racing red if its going on grey machine ?

Cheers Mick

Cheers Lads

When I get things sorted I will do a how to , its just photo etching not at all hard to do

I will pick up some spray paint tomorrow , I only have Black on the shelf , must remember some wet n dry as well .

Thanks Rob

I like the etchings. Fantastic stuff... another thing I need to learn to do!

RobWilson · « **Reply #63 on:** February 23, 2015, 02:47:39 PM »

Cheers Bob and Eric

Decided to try a Blue infill

Still room for improvement ,a few things I need to work on ,like were I cut through the plating

, but for now it will do to slap on the forge

So, which etching method do you use? Is it basically like making PCB boards (shine light through some positive printout, develop with NaOH, then etch with FeCl3 or something like that)?

doubleboost · « **Reply #65 on:** February 23, 2015, 03:01:01 PM »

Very nice mate
It would look great in dark green

That should dress up the forge right smart, Rob!

Aye its all aboot the BLING Steve ,,,,it wont make the forge work any better

Think I will have ago at some Aluminium plate and Anodize them to see what they look like ,,,,,,,,,,,, may look cooooool

That's real swish looking. I'll have to have a try at making some plates myself some time. Is it just steel?

I used Brass Simon , Steel should work OK , I will be giving Ally and Steel ago .

Could brick acid be used for etching as that is easily available and pretty cheap ?

kayzed1 · « **Reply #71 on:** February 23, 2015, 04:58:20 PM »

Very Very nice Rob, but i bet you have bought a new even better camera

cos your stuff looks more betterfull ( is that a word ? ) than ever.

Lyn still trying ...

It it's the same as muriatic acid (dilute hydrochloric) here I generally use that for cleaning scale and zinc off of steel, but it seems to leave the steel intact. Maybe because it's diluted, or I didn't notice -- even after a couple of mistaken overnight cleanings in it.

It also seems to work well to clean scale off of brazing and copper based parts that I've tried. But again, i didn't notice it eating away the base metal.

It will really tear into zinc, though!

Hi Joules , I used Ferric Chloride (the same gear used to etch PCBs ) , if you have Brick cleaner (usually Hydrochloric acid) to hand then give it ago , it may work .

,,,,,,,,,,,,, and no same camera ,just better at Photoshop

I forgot -- I have done electrochemical etching of steel -- to make reed valves for pulsejet engines. Maybe that's a possibility. But i think there'd be some undercutting of the letters if you went anywhere near as deep as Rob has.....
