Pneumatic Assist 3 Way

[86r]

I'd like to try my hand at replicating the tjd pump lite kit.

Realistically, how hard is this going to be???

I have zero experience.

I don't have one in my possession to emulate.

I don't have any tools.

But i have the will!

Be gentle please 🙏

The "no tools" part may be one of the hardest parts to overcome. One presumes you'll at least need a knife to carve it out of wood, or a stick to knap it from flint.

Do you at least have access to any tools?

Doc.

Okay, i meant like big boy tools. I have a myriad of small electric tools and hand tools.

I didn't expect YOU to reply - now i have to sit up and pay attention.

Should i buy a cheap 3 way to experiment with - to start?

Buy an old kapp 3 way, flip the three-way shaft to the front, put timing rod on add spring under that. Done.

Kapp 3 ways have a front threaded retaining screw.... Its built in

Okay. I will report back eventually.

Ahh that would help

Back when I made my "Phantasm" pneumatic-assist Phantoms, I used the old cup-and-clip 3-ways. That was partly because, well, that's what was available back then (I made the first one in 1998) and second, because the inner spool was retained. A small spring, an timing rod coupler, and a countersunk 6/32 screw was all you needed to make a self-contained, spring-loaded switch.
