Yet another 2-1 build

[lock-ed]

I have seen many, very nice step-by-step in 2-in-1 picks.

This thread does not bring ground-breaking news, but might serve as inspiration to some.

Please bear with me.

First, choosing the right tubing. These are a 5x3.2mm(outer Ø 5mm, inner 3.2mm diameter) main shaft from an RC-helicopter, and a 6x5mm stainless tube found on ebay.

[lock-ed]

Next, increase inner diameter on the smallest tube to 3.6mm.

Tested in the lock, and I can now move on to the active parts.

Made a 4.8mm hole in some 2mm steel, and a rough sketch, before placing in the vise and using my trusted jewellers saw:

Moved it to the fireproof tile, and silver-soldered

The back to the lathe to turn town the tip, in order to make it fit perfect in the lock:

Tried first by hand, but quicker and better finish when done in the lathe. Also gave it a touch with a countersink to give smooth operation.

And yes, the tube protrudes slightly to compensate for the thin metal that should have been 3mm

[lock-ed]

Now moving on to the outer part. Made a 5.8mm hole in 1.5mm steel. VERY happy with the nice and tight fit, after treating it with a small roll of 240 grit paper.

Cutting the rough profile with the jewellers saw again, before another round of silversoldering.

wow, real nice pictures. if only i had access to those tools...if only...

Superglued a small, knurled aluminium bit onto the outer stainless tube. Not convinced that this will be sufficient, but willing to give it a go. Have good experience with superglueing handles before, but not as small as this one.

Thank you pin_pusher. If it's any comfort, I felt the same for 9 years before finding the time and money to buy a small lathe and mill.

However, very much of this can be done with a small vise, small saw and some half-decent files.

Having a full-time job behind a desk, I am learning practical machining every day from other people on internet. But my best teachers by far, are my own mistakes.

A wise man once defined an expert: A person who has committed all possible mistakes within a narrow field.

Assuming that is correct, I am making GREAT progress

And by the way, pin_pusher, what tools would you make?

good question...i'm working on a disc detainer lock pick at the moment, just with some non electronic tools. that is to say, not so accurate (probably a little more time consuming). i also work on typewriters, making parts, cleaning and repairing so a jewelry lathe would be a great investment. the jewelers jigsaw would definitely come in handy for making some different templates for both lock picks and typewriters. especially like what you've done with cheap materials from other equipment (i.e. rc helicopter), saves money making your own tools i would imagine. fortunately i do have a grinder, got a great deal on a dremel, and a racketty ol' drill press. still not complete however. (can one have enough tools?) is there a tool to get me out of work, so i have more time for hobbies?

I envy your lathe and mill
