where to get AA dummies?

[270winchester]

Hi folks:

like the title says, where is a good place to get them? or can I use an uncharged rechargable NIMH for that purpose as well?

THanks

I wouldn't use batteries for dummies. C Crane used to sell AA dummy batteries, but they are sold out. You might be able to buy some if you run an add in B/S/T. I think most of the guys are making theirs lately. You can make one out of a metal dowel rod in shrink wrap or a wooden dowel rod with a nail through it etc.

You could go to the hardware store, buy a 1/4" bolt in the correct length and a couple of spare nuts. Cut the bolt to the length of the AA and round the end. Lock the 2 nuts together hear the end. Wrap tape around it until you get the diameter you want.

Steel might give you more resistance than you want in your dummy AA. If the spring tension isn't too strong in your application, you could just roll some aluminum foil in the length and diameter of an AA cell. /ubbthreads/images/graemlins/cool.gif

I made a few dummies from some aluminum rod I bought at home depot. The rod was around $3-4 I think for 3 feet. Just buy in your appropriate diameter, or next smallest and cut with a hacksaw to length. The application I used did not require insulation from the body as it was not used as a ground path, but insulation of some kind around the aluminum is probably required.

Yo, 270; Go to Aljacobs.com. He makes the things by taking a Delrin tube, same length as an AA cell, drills a hole the long way through it, lines it with copper tubing, and puts a self-tapping screw in either end. They cost like $7.50 a pair, with little resistance built in. He uses them in power packs for photo flash units. They look easy to make, if you had access to a drill press.

You can also order them from me: $3.50 each plus shipping. Email me for ordering. Mine are solid Delrin outside with a solid Aluminum core - very low resistance.

DSpeck do they have a tip or are they flat dummies

 

[DSpeck]

They have a tip, similar to a regular AA. The bottoms are flat, and flush with the Delrin outer sides.

I got a stick of 3/8" Aluminum, cut with a hacksaw, and put electrical tape near one end and flush with the other.

I also dressed up the ends a bit with a file.

Worked fine!
