I tend to use a drill to partially seat them
then once seating roughly I run it ob the mains.

Or if you're lucky enough to have a variac then use that.

I always just

Clamped the motor in a vice so it cant move, Then hook power to the motor leads and as its running just use a commutator stick lightly until it stops sparking,If you don't clamp the motor it is liable to jump off your workbench when you turn it on.

Ill try hooking a drill to the armature. Thanks, Emma!

seating

depending on the machine I either use a variac transformer, drill, or if you do not have access to neither of the 2 you can make a variable speed switch using an outlet and a light dimmer switch.

You're welcome

Sorry about those few spelling mistakes. Just proves it isn't a good idea to try and type quickly when tired and having a drink haha.

Use a carbon brush seating stone. That's what they are made for. I'm sure you don't have one, but you should buy a box of them. They are not expensive and will last a long time. They are a necessary part of a motor rebuilder's tools and supplies (as necessary as bearing grease or a socket set).

I dont have a vice here! Nor do i have a seating stone. Where can i find one?

 

[vacuumlover]

Ebay,amazon.

 

[vacuumlad1650]

Ill take a look. Thanks!

A carbon brush seating stone will cost me 70 bucks! Thats more than i paid for the brushes, vacuum, and new armature combined!

 

[mchmike]

You're right about cost . Here is a less expensive method and the one I use . It works and sandpaper is cheap.

 

[vacuumlad1650]

Actually, a Kirby Guy named Bill called me. much cheaper, 15.75 for 4 sticks!

 

[vacuumlover]

Another method i forgot about is using wet and dry sand paper. When I use this method what I do is try and wrap it around the commy (between the brushes) and rub it back and forth to shape the brushes. Working from coarse to fine.

If I do this method I tend to use the drill afterwards to seat them some more.

!5 bucks

Is way more expensive than we ever spent on them in the vac shop I worked in...of course it was over 30 years ago...lol, You don't HAVE to have a vice, you can hold the motor with one hand while turning it on, the thing is the torque of the motor starting will make it twist and if you don't have a firm grip on it it could jump off into the floor, when it is running it wont have that twisting motion, but the airflow can make it move.

 

[vacuumlad1650]

Well, lets see what happens...how do i seat the brushes with the stone and drill?

 

[vacuumlover]

When using a drill I stick the motor shaft into the chuck, tighten it up and tun it low gradually gaining speed.

If you want any pictures let me know and ill try and get some as soon as I can.

 

[vacuumlad1650]

That would certainly help, Emma! Ill go dig my variable-speed drill out tomorrow, my Grandfather gave that to me years ago!

 

[vacuumlover]

I'll try and get some tonight then
