need some of these making out of steels

[bill thompson 1Participant @billthompson1]

I'm not sure how difficult it would be to reproduce these in steel? your thoughts please

[bill thompson 1Participant @billthompson1]

[Rik ShawParticipant @rikshaw]

I suppose a lot depends on how many you need making and a rough idea of what you'll be using them for – they look like a catch or a lock to me.

Yes, it's a part out of a locking mechanism, I need at least 25 of them, I'd be looking to pay around £5.00 each to have the part reproduced in steel, the die cast is prone to failing and breaking up.

[bill thompson 1Participant @billthompson1]

I'd probably be needing more in the future too.

£125, that would not even cover the cost of an 8mm broach to make the square hole unless someone willing already has one.

Do you have a CAD drawing as that would be the quickest way to make them and would save you paying someone to also measure teh part & draw it up

[bill thompson 1Participant @billthompson1]

unfortunately no, I thought the square hole may have been the sticking point..

Hi Bill T1,

What about an half inch socket, as in spanner?

Regards, Bear..

[Oompa LumpaParticipant @oompalumpa34302]

Cast them in something substantial?

Just a thought, it would be much cheaper to reproduce them. They look like they could be made half 'metal' half curry powder from the photograph.

[bill thompson 1Participant @billthompson1]

here's one in steel, so it can be done, not sure if the square corners have been achieved by broaching..

[John HaineParticipant @johnhaine32865]

You might be able to print them. See:

Steel- 3D Printing Material – 3D Printing Material

you would need to generate a CAD model.

[bill thompson 1Participant @billthompson1]

they have to hold their own in terms of mechanical wear and tear temp range -10 to +30 degrees Celsius outside temps, good shout though

That's looks like it's part of a UPVC style door lock?

I have a door at previous workplace that always breaks those, it's a nightmare, we replace the lock every 6 months – 1 year!

Hi Bill ,

Ideal component for lost wax casting in mild steel .

(I say mild steel but you could just as easily have them in Nimonic or Titanium if you wanted).

Easy simple process to get things made lost wax . You can do most of the work apart from actual casting yourself though there are several turnkey companies that will do the whole job for you .

bang on! upvc door lock the whole unit costs £100.00ish,

I've done some digging and have managed to source them in steel ~ delivered £22.50 each!! grieves me to pay it for such a small component, but hey such is life,

wax casting in mild steel? that sounds interesting.. Tell me more about the process.

[John Stevenson 1Participant @johnstevenson1]

Probably cost £50.22 in lost wax and steel casting

[bill thompson 1Participant @billthompson1]

I've a relative who works in a foundry, giving me ideas now,

[Sub MandrelParticipant @submandrel]

If I was making a small run of those I'd silver solder two bars with 90-degree vees in together to make the central square hole.

Not for £5 each though.

[John HaineParticipant @johnhaine32865]

Shapeways steel goes up to 800 odd degrees.

[mike mcdermidParticipant @mikemcdermid41977]

Stack them up and wire erode the square hole
