Actually, I think maybe that these Handi-Wipes are NOT

A puller like that would be nice to have but I am afraid that there is

It's a counsel of perfection, I guess, at this stage, but I would use a puller
fitted with very thin lips at right angles to the legs. These are desi

Mine was also taper roller bearings. The front one was very badly worn.
You should have earned me before but once this is sorted out it should
be OK I hope.

I use a large plastic box and I have 3 settling compartments in there. So the
coolant fills the first then spills into the next and the next each time
dropping more swarf. A trick is to drill holes in the tank separators near
the top but below the liquid, that way nothing floats over the top. It

To take out a bearing cup I use an arc welder and run a bead of weld
around the inside o
Also when I have a really bad stuck bearing race I usually run a tig weld
around the OD of it and that usually frees it up and often cracks it enough
to just hit it with a chisel and mallet and it falls off. I am sure you
probably don't have a tig welder but if you cannot get it off you might

I know most tricks how it should be done in theory but have some limited
experience practice. There are also some difference to be in a well supplied
electronic lab as solving the problem in a limited time with some scrapped
chokes avialable at the same time take care of a child.

Where there is no provision for pressing out I use a dremel and grind
a slot to weaken inner or outer, needs care and a steady hand but has
got me out of trouble a few times.
Sharp tap with a chisel/punch to break it once weakened.

So a little bigger tap with a little bigger mallet did the job. The
front bearing fell apart and is badly worn.
Now the seat is stuck inside the headstock and the bearing piece is
stuck to the shaft and I have no idea how to get it out.
Anyone know how to get a stuck bearing seat out please?

The typical $100-200 coolant units have a screen in the return inlet to the
tank to catch big chips, and a baffle in the tank so the smaller chips in the
coolant that pass through the return screen will settle to the bottom of the
tank in that chamber while the coolant will flow over the top of
Hello!
I decided to set up coolant on my router to make it easier to work

For coolant pump I used windshield washer pump from unknown car

A small value capacitor decrease the problem so I guess the commutation spikes
are the problem but driving a capacitive load is not good.
