Default Anyone has a Steel capable lathe?

I may need to make some custom steel pins for a landing gear. Ordering small parts from China is just not feasible. I can provide a 2D sketch or a step file.

Rough dimensions are 3/8 OD by 3" Length, with a .060-.080 E-clip groove on one end.

Anyone has one at home? shop?

Thanks,
David

David,

Make your own.

Order the 3/8" rod and clips from McMaster-Carr. Cut to length. Spin it in a pillar drill and use a cut-off disk in a Dremel to make the groove.

I did exactly that for a replacement nose gear pin for my SM Xtreme Hawk. A $4 part from SM but with $25 postage.

I can now make them for about 50c each.

The rate I go through them I can save enough for a new plane.

Glenn, thank you so much. I will try the method suggested by Paul, but if I can't do it I will provide you a sketch.

Take a look at an injector pin. They come in all sizes and have a button on the end.

Agreed!
I have been making wheel axles out of music wire this way for years. I have even used a hand drill on occasion.
Use the extra thin cut off wheels (the ones that break really easily) for smaller E-clips.
I usually cut the groove first, then cut the axle to length. That way if I screw up the groove by cutting too deep I can just cut it off flush and start over without wasting very much material.

Good planning Kevin! You can write my production planning any time! :-)

Wana bet?
Drill rod will bend, and if you bent it very far it will break.
Unfortunately I learned this thru experience.

FalconWings, McMaster Carr product 92735A480. It is a 3/8" 3.50" long 18-8 stainless clevis pin with a head on it. Has the groove already in it, would just need to cut the head off. They also have a zinc plated steel pin of same size product 92735A855. That is if either one of those are strong enough and you are lazy (like myself).

Hi David.

We are distributor of the Ultratool brand in Texas.
They make some of the best solid carbide tool blanks available in the USA.

We don't have this specific dimension in stock but can order it any time if required. In case SS or hardened steel is not strong enough for your application, this is the way to go.
Just be aware that this thing is real tough and will eat most of your regular tool happily...
