Machined M@g C extension

[jimjones3630]

Looking for an idea of how hard/expensive to make M@g C 100-105mm extension with ID 26.25 or more made out of stainless? something strong because think to screw onto C size will be fairly thin walled. AW aluminum C extender colapsed when bored out to 26.25.

not sure what you are doing - but will a longer 'C' light cutdown and bored out work?

Want to put the described C M@g size extension onto a 5 M@g C. Since 5 is about the only size can get. Rarely, a 6 or 7C comes available. So 100mm added to 5C will enable to use 5xemoli cells.

Do you think stainless would be strong enough?
Looking for someone tell me if this extension is doable and made out of what?
then find someone to make it.

I would not know if stainless is strong enough, I have a mini-lathe and I can't work items that large.

thanks for inquiring. people make D size extensions out of aluminum, alone know of AW small C extensions and they do not have large enough ID for A123 or emoli cells

AW aluminum C extender colapsed when bored out to 26.25.

Aluminum spec's I use don't use AW so I'm not clear on that metallurgy. Just curious to politely confirm you know you're using a v. stout aluminum grade already before going to SS? The machining jig/process is also key - is this when it collapsed? If so I'd suggest rethinking the fixture/holding method. For starters I'd suggest a slip in insert to provide internal support if being jawed externally... I had some 2"+ ID tubes for other use bored quite thinly but machinist got secretive about me seeing his jig but I believe he internally supported one side while boring the other end etc....and then in reverse somehow.

Good luck and let us know what you come up with.

For Jim's ( and mine / others) use I dont think an internal slip insert would work, as Emoli cells only just fit into C mags as it is with Increadibly thin tape.

I think the best thing we can do here Jim is get the whole tube made out of SS.

It would be stronger, and ready to go, as far as internal diameter for accepting the card wrapped Emoli or A123.

I think when we were finnished the only aluminum bit would be the bell, as with FM SS tail cap, proposed S.S. body & S.S bezel.

I'd be well up for some SS bodies in rough 7C format and , 420mm lengths, or maybee extentions to make adjustable, and I already have 3 x 7C's, but would like more than 5 emoli, hence the 420mm tube, or extentionable tube.

this can all be done in the 6D + extentions, but the C mags feel good in the hand.

I'd love a all SS maglike "C" Frankentorch.

Maybee this is one for Five Mega's thread on "whats missing"

Or one for Leef? or Any other modders / Machinists.

Maybee I could take out a second morgage if this could be done in titanium :naughty:

I think Raoul has the best idea. There's not much to a Mag tube; if you use a tail switch, the only Mag part you'd be reusing is the head and bezel. And since you'd be using an aftermarket window and reflector I sorta wonder if you should just get a new head made too!!

 

[jimjones3630]

I like the whole stainless steel body, but cost is a consideration for me hence, looking for a simple M@gC extension made out of whatever will work haveing an internal diameter >26mm, A123 &Emoli OD without their cardboard sleave.

If the thing can be made out of v. stout Aluminum sounds good to me. My experience is with AW's C cell extender only.

So, Westly thanks for the ideas.
