I will look into the use of Hydrochloric acid as an etchant , but I think it needs to be concentrated and will only work on steel , I could be wrong .

Well forget Fanny Cradocks cook book ,,,,,,,,,,,,,this is a cook book

,,,,,,,,,,,one of mine

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.....

Yer Steve , lots of thin steel parts ,like the reed valves of a pulse jet are etched .

Nice book Rob
Be some real healthy concoctions in there
The thing is they worked then & do now

Rob, do you think electrochemical etching would work for a steel nameplate? You only use salt for that.

vtsteam · « **Reply #79 on:** February 23, 2015, 05:46:21 PM »

I learned electrochemical etching from Bruce Simpson a dozen years ago from his old website. I just did a lookup and found he has a new video on Youtube that goes into very good detail about the whole process. Here:

Yer ,Steve , there is a professional system for etching say a company brand onto an item that uses similar .

This video shows a steel belt buckle being salt water/electro etched to good depth of relief.

A similar salt electrolytic process is often used by bespoke knife makers to etch a design onto the blade,but they use a cotton pad electrode similar to the vid Rob posted.....OZ.

Apologies, Rob for getting things diverted

-- I momentarily got excited about the possibilities after seeing what you'd done.

I really admire your historical knowledge and approach to making things, including traditional etching and plating. That fantastic forge is really the focus here!!

Hey no need to apologise Steve ,its all good

I really don't mined one bit , threads are like conversations that drift and at the end of the day a few new things have been learned and ideas kicked about

Hi there, Rob,

I hope you're well.

I'm reading this thread with great interest. I keep thinking, 'Uhmm. All-in-one tee-bolts with forged ends...... '

RobWilson · « **Reply #86 on:** March 04, 2015, 01:03:01 PM »

Hi Pete

Yer doing OK , well had a slight blip the other week and ended up in A&E

but thats another story

So looking to get back on with this this weekend , yes forged TEE bolts would be nice ,along with a good few other bits of tooling i could name . The main ,well one of the main reasons for the
forge ,like the furnace is to recycle material that would normally be thrown out . doing my tree hugging bit

Wow amazing work.
I'm sitting here in awe

Cheers Lee

Thought I would do a bit more to this project today , I fabricated the square to round transition piece for the end of the blower and also welded on a bolt flange .

I think I will get cracking and finish the air flow valve next

Cheeeeers Rob

A cracking bit of tin bashing there Mr. Wilson.....

Once finished the forge could double up as the family bar b q.......

Sausages at the ready........

Well mine did for many years - I even put it on locking castors to pull it out of the foundry into the garden. With the blower, and a blow lamp it was the fastest starting bbq I've ever had !!!!

Cheers Lads

Made a start on the ash dump today ,plasma cut the parts from 6mm and 12 mm stainless . On my state of the art plasma table LOL .

And after a bit of a clean up . Sorted !

Was that freehand Rob, or did you make a template? I rarely use my Plasma cutter as I make such a bosh of cutting to a line

That was all BobCam Andrew

I did cut a sheet metal template out just to save marking two out .

awemawson · « **Reply #98 on:** April 26, 2015, 02:50:03 PM »

OK I'm confused (or so I'm often told

)

So you drew it in Bocad - do you have a CNC mill to cut it or what? My plasma torch needs quite an offset from the cut line due to the (??18mm) diameter of the torch, so how did you follow a template that appears to be true size?

(Or is the bottle of Merlot I'm drinking interfering with my thought processes - it's certainly affecting the typing

)

RobWilson · « **Reply #99 on:** April 26, 2015, 03:12:49 PM »

I was taking the piss Andrew BobCam = RobCam ,

I drew the profile out on a bit sheet metal , then drew round the sheet metal template with chalk (twice) ,then followed the chalk lines with the plasma cutter free hand .
