Hi everyone model engineering is not my hobby but I do love some of the stuff you guys create, I’m really struggling to find someone to machine a part, its for a 1920s printing machine I have one but need 10 more everyone I’ve contacted seems to think it’s impossible to make but they managed it 100 years ago so surely it must be I think they are just not interested, could I post up some photos and see if you guys think it’s doable thanks in advance

Hi Jo.

Certainly post some pics in an album and attach to this post so we can see the part to be copied.

Is it turned or milled? Or maybe cast if it's a complex shape.

Most things can be done but its usually a question of cost. A company would have to charge to make one off or short run pieces so it's easier to say it cant be done. A bit like a builder not wanting to bother with a simple repair, it's not worth their while.

But a home machinist may tackle it if it's not a complex casting job.

Best regards Mick

Hi Jo,

A drawing or photo with a few dimensions would help. You also need to tell us where you live. There are members all over the world. I am in Australia.

Anything can be made. It's only dictated by time and money.

Hi here it is it’s hard to see but it’s about 4mm diameter it’s basically cylindrical for the first 1/3 then it has 3 grooves running down each side so it then turns almost triangular and finished with a point, made of metal hope that makes sense thanks guys

Looks straightforward. If someone said impossible it must have been followed by a modifying comment such as "for no cost" or "at a price you will pay" . Were these professional machine shops?

Hi yes all proper companies they seem to think cutting the grooves is the hard bit but I just think they had no interest probably more interested in large runs for big companies cheers

You can cut the grooves with a suitable radius ball nose cutter and the work piece supported along its length. Turning the part through 120 degrees can be done in numerous ways. You probably need a hardenable steel but that is also not a problem.

Hi Martin thanks you make it sound so easy haha, so would they just use a rod of hardened steel and cut into pieces then shape the grooves thanks guys

If anyone knows of anyone/company that could do it I’d love to hear many thanks

Looks like a job for a tool post mounted grinder, cutting something that small with a ball nose cutter sounds unlikely to me.

I suspect they would have been forged originally.

Hi

You may find a sewing machine needle that can be adapted to your machine, maybe you could get a longer needle and remove the thread eye and make a blunt point most will already have a groove. The material will be high quality hardened steel so the result will be durable. It can be ground easily but not turned.

Locally industrial sewing machine suppliers will have needles.

The link below may assist also, Schmetz are a leading manufacturer of needles.
Send them the dimensions of your needle

Regards
John
