Stuff you have made today

[Brad93]

A pile of segments rolled for @grim_d .View attachment 331630

Did you do these individually? How did make sure the ends aren't flat?

Or did you roll over length then cut down

 

[awemawson]

Yep, hard work in en24t.


Didn't think of it.

Should have sent it to me. I already have an EDM diesinker electrode that I made for 1/2” drive sockets !

Becoming tedious parking the digger,then walking back to gather tools,so I made a rack.
I’ll add it to the next galvanising trip.View attachment 331462View attachment 331463

Don't think your digger got the MMR vaccine

Rolled 1m bars,then cut.

When you've perfected casting brass I'll have a commission for you. Hopefully I'll be able to supply a suitable mould...

I was intending to try brass tomorow. I want to see what this can do incase it fails, I'll know what needs to be redesigned. Power is no problem, unsure about the element life and how well it is retained.

Turned the cast bar, swiss cheese! No worse than my attempts years ago, but I have some ideas for next time. I drilled 12mm and found a hollow to one side. In centre.

Had a peek under microscope, really needed a better polish, I gave a quick sand p800 and p1200.

Finished correcting insert pocket and tapped for screw. Next to grind the clearances.

What are you intending using, plumbing fittings?

I have maybe 10kg of clean with my name on it, to collect sometime. Basically brand new nuts and olives and lots of them. Surplus as the company changed the valves on a job but reused the old nuts and olives!

My plan is to mirror a photo (the pub) then 3D print it with height/contours, spray mould release on it then do a plaster cast...or something like that!

Thinking some more...do I even need to mirror the photo? Don't think I do...I can just pour plaster on the print. Basically I want to recreate this in brass (as opposed to the PLA here), maybe twice the size later too if it works:

Finished a pallet of sheetmetal for a customer who is making some huge sheep feeders. 2mm sheets, there's a decent chunk of weight there!

What are you intending using, plumbing fittings?

I have about 5kg of old taps and fittings, old gas regulator and about 1kg of swarf. The taps were chromed which may be a problem, would I be left with a chrome /nickel shell to fish out, or would it disolve into the melt?

I doubt I can achive that level of detail but would be interesting to try. The picture would suit electro growing if you start with a negative 3d print?

Another mini excavator bucket in production
This time I'm completely fabricating it from zero.
Cut the sides from 6mm sheet using the plasma cutter .
Welded together to make them identical using a grinder.
This evening hopefully I'll have ground them up and bent the bottom plate .
It's a small 5 or 6" bucket i still have to know the width of it.
Quick change from the shelf.

 

[awemawson]

A very small amount will dissolve but really not of consequence. The shell as you call it is unlikely to stay intact and can be skimmed off with the oxide dross. Are you using a cover flux?

PM me your address and I'll send you say a kg or so of these clean plumbing fittings.

What's electro growing and can you do it with brass?

 

[Kram]

Its a copper plating process, but it can be converted to brass if followed with zinc plating and heat.

Short video under microscope. Somone has suggested it is shrinkage porosity rather than hydrogen bubbling - that explains the centre hollow. It seems to be a problem with high sillicon casting alloys.

That's a good trick. Any pictures of you doing this?

Is this for work or your own job?

 

[Kram]

Ground the shape, its not pretty but theres reasonably good transfer of blue from insert to the pocket sides so Im happy with it.

 

[Memmeddu]

Nope unfortunately there's no time to make photos.

It's for work .
Today I've done only metal fabrication.
I'm also repairing a small concrete mixer bath .
Welded an F clamp , made two of them work again (seized screw) using the propane axe (it's cool to call a cutting torch this way), and little bit of elbow grease to move the screw.
Then greased the screws to keep them moving
I've welded all the evening.
Hopefully hopefully , my work is taking the right direction.
Employers are happy with my welds .
And I'm making progress with the mig welder.
Again as I've said the other day .
Let's see how it goes.

It was a joke. The sentence reads somewhat differently to your intention

Well , I've dreamed for years and years to work in this sector .
Those two days were not perfect but way better than the last week or two.
Let's see how it goes , I would not take a bad decision in a hurry.

 

[Memmeddu]

So bucket done
Inside welds on the picture of the bench are not mine (boss done them) all the others are mine.
Concrete mixer repaired , thin rusty , painted and covered with concrete frame with galvanized steel reinforcement ,mig welded vertical downhill .
I don't know if are acceptable .
Anyway let me know if I'm going well

Today i made a lowly poker, but with my first ever rams head top to it. Done at Rich maynards forge at Much Hadham hertfordshire (see post on metalworking attractions) Im well pleased with how this turned out.
