Side note, any hints on cutting the strip?


Buy a metal-cutting abrasive disc (chop-saw disc) at the hardware
store in a size that'll fit your table saw. It'll zip through 4130
nicely. Lots of noise, lots of sparks, so wear hearing and eye
protection and make sure your work area is free of anything that might
burn or smolder.

Great for entertaining the grandkids, but not so good if you're an arbor
bearing. The grit accelerates wear... yada yada. For stuff that size, buy a
small bench shear from Grizzly or Horrible Fright. It'll cost less than
overhauling your good power tools, not to mention being generally useful for
sheet metal work.

I haven't had a bearing fail on my saw yet but I think I could buy
quite a few before I got to the price of a shear.

Been cutting steel on a couple of tablesaws for a long time
now. No bearing hassles. If the bearings were really old and the seals
were gone, it sure would be a problem.

I third your no problems.

I have an Old Milwaukee circular saw that I have been using since 1982, and
a good part of that was 5 days a week professional carpentry. It has also
cut way too many feet of steel to count, up to 3/8" thick.

It has never had the bearings touched, or even regreased.

I'm not sure how much of this is a testament for the saw's manufacturer, or
that cutting steel will not hurt bearings.

I have had a bearing problems with my Skil Saw. Not the motor, but the guard
bearing is very rough from cutting metal siding.

While *most* sealed bearings found on motors or jackshafts *shouldn't* have
a problem. A number of guards and guides found on woodworking equipent were
not designed with metal grindings in mind, and they can indeed cause a
problem.

Also, most quality friction saws designed for steel include TEFC, totally
enclosed fan cooled motors. While circular saws and most table saws do not.
And unlike wood dust, the build up of metallic duct inside these motors can
easily cause dangerous and catistrophic failures. Read *fireworks* and
shocking experiences. Especially in the quality metal framed tools like the
older Skil and Milwaukee brands. So your mileage may certainly vary.

The only problems I have personally experienced with Old Milwaukee brand
products were different levels of morning sickness.

That is a definite problem, but easily cured by taking apart the guard, and
cleaning and regreasing the sliding surfaces. That is all they are, is two
pieces of metal sliding on each other, with a brass shim between some of
them.

I have had far more problems with the guard gunking up cutting concrete and
other masonry, than cutting steel. Again, about a half hour, clean the
guard, and back in business.

chuckle That HAD to be a Freudian slip, or something. I too, have been
harmed far more by OLD Milwaukee, than by my Milwaukee circular saw.

No doubt, those blades make a mess. Cleaning is a necessary part of the
deal.

Nowadays, diamond blades are cheap enough to justify using them, over the
sacrificing blades. They are much cleaner.
