Milling a sub motor

[Zade08 10+ year member]

Any one have any thought on milling out a top plate for a sub motor? I need to have new basket holes tapped and the top plate milled out to a 3" coil.

i pop top plates and machine them all the time. you cant when the motor is assembled. you cant make a 2.5" coiled motor isnt a 3".

ur avatar need implants,lol....

it is a 2.5" coil motor. Only real problem is the gap is to narrow so Ill probably have to just machine it out to fit a 2.5" 8 layer flat wound.

Is it hard to recenter the top plate when I yank it off? And also what is the best way to pop it off and what kind of adhesive to reattach it?

Thanks for the reply. ya its the ex from a while back. Haven't changed the pic in like a year. Although I like a b cup. Nice and perky 10 years down the road. lmao.

its not something i would tell anybody to go ahead and do. its very dangerus you can get cut bad or loose a finger playing with a charged mag.

D cups is where its at! you can always get them lifted, its like a **** recone //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Lmao. Im pretty sure the top plate on the motor is aluminum. Shouldnt matter if the mag is charged or not. My brother and law works in a machine shop so i can get the top plate retapped and milled for free. My only issue is what is the best way to remove the top plate with out chipping the mag?

Btw I came to you becouse Iv seen csome of your work and it is a gorgous thing.

Nope, it's steel...

well ****. Guess i gotta look around and try and find a hooh up with some one to de/remagnitize my ****.

Thanks alot for the info guys. Really helped out.

Oh ya not to mention recones cost about 100 each. Last time I checked ***** cost about 3k each. ****. ::Facepalm::

top plate is low carbon steel. you wont want to mill the top plate because you have to indicate the top plate to bore, by the time you do that you can chuck it in a lath and bore it out. takes no more than 5 mins...

Is there any possible way to remove the top plate have one machined from aluminum to the exact specs and replace it or will it lower the structural integrity of the sub?

You can not simple replace a low carbon steel with any non-ferromagnetic material such as aluminum. I would hope you would understand the effects this has on the way a motor opperates.

First off you can not simple "demagnetize" something. You can place the motor sideways in a magnetizer to reduce the magenetic feild but at any point there will still be magnetic force. The other option is to thoroughly heat the motor to about 1000degrees where it will lose all its magnetic integrity while keeping form. This will also get rid of most of the glue for you as well.

It is possible to remove the top plate without demagnetizing it but as said by splaudio it is very dangerous. I have had magnetized plates reattach to the motors with hundreds of pounds of force and if my hands were any closer I would have shattered the bones in my fingers into a million pieces. at this point I would say you are better off simply getting a new motor. It would save time, money, and be safer.

as bumpin said you need to understand how a motor works if you had a alum top plate your motor wouldnt work.

dont try and take ur top plate off please its not gonna be purdy, esp when you try to reassemble. i see broken mag slugs and fingers in ur future.

i make fictures for a living so i have a long background in this...
