Aluminium Armature Bar

[OwlsDen]

Not to forget that a soft metal will have some flex to it. It can also be weaker where the inserts are for the coils. Is the point to try and make a low voltage machine? Because No Iron makes a good point, it could run too fast. You may need a larger capacitor an run it at lower voltage. Then you have maybe a quieter machine that runs fast at low voltage. It is a lot of work. I am curious about what you are trying to do.

if you want it to be lighter, just mill it out...then you don't have to mess with threaded inserts and laminating strips of steel and what not.
technically, you need a bit of meat on the a-bar to make the magnetic connection better..
but who needs coils anyway. lol

Yeah, it is a strange conversation for a forum about rotaries. I like it though, it's fun to ponder these things.

This is a cut down A-Bar

There is the old cycling term you can use for making things lighter ;-) make it out if "drillium"! Take the same old a-bar and drill holes in it until it's as light as you want it to be.

Seems pointless and silly to me, the plastic with metal could work for vibration sake but I dont think it would improve anything.

Funny...I already don't like the way most aluminum framed machines sound...can you imagine how one would sound if an aluminum a-bar were even possible? Ouch!

It would also likely hammer its self into some kind of deformed mushroom in short time. There are many clever and aesthetically pleasing ways to weight weeny an armature bar. You can shop around or ask one of the coil builders on here to make you ultimate in form and function.

I have made two protos, its an aluminum armature bar with a 1018 Cold rolled steel of about 1mm.
I dound no point to do that as you can always shave down an armature bar to get rid of weight.
The two pieces aluminum one made that machine nosier and less consistent.
The a bar on a coil machine needs some weight.

HEY CLONE BOY, but u talking about ARMATURE BAR for coils machines?
impossible work that is not MAGNETIC MATERIAL, the only way u have for ALUMINIM ARMATURE BAR, is put a insert of IRON inside where the HEAD of the coils touch the ARMATURE BAR, that's all

but not realy have to much sense have ALUMINIUM A.-BAR, for what? for go more fast? probable the machine like that gonna run more than 160 HZ, is to fast, no good for tattoos

U EVER BUILD MACHINES BEFORE ?

If you read the 3rd post then all your answers to this post are there and no, i have definatly not built machines before.....haha
