Yep. It's been 26 years since I added a room to the old house and
hung drywall... my office. And I cheated... rented a special sprayer
to put down "orange peel" ;-)

1: neat tool. I assume its similar to using a router in that guides are
helpful for straight lines.
2: Opti-visor (like mine)
3: good camera. What is it?
4: Sorry to hear about your son. My condolences.

They are called Roto-zip tools, and they are nothing short of fantastic,
for what they were intended to do. Somewhere, someplace, they got the
idea to hang everything, including the kitchen sink off of the tool, and
sell them to harry homeowner. I think that was a dangerous mistake.

With the proper bit, they will cut most anything, but they are more than
a little bit wild. They will core you if your aren't careful. The bits
will break in a blink when they get dull, or if you force them.

Using them with fly cutters, and router bits is an accident waiting to
happen, yet they are encouraging just that kind of use.

When they built the new high school where I grew up, a wood and auto
shop were included. Within a few months, two fingers were missing from
students (two _separate_ incidents of trying to clean shavings from the
planer as it spun down) and three from the shop instructor (table saw).
After the instructor spray-painted the large tools using his
abbreviated hand as a stencil the carnage stopped.

Later, a friend of mine removed one of his fingernails with a router.

Great tool. How do cut a straight line?

A fly cutter in a high-speed handheld tool??? That would take the kind of
doofus who searches for gas leaks with a candle. I can see using a small
router bit, if you have the router base.

When my oldest son was at Chaparral High School (North Scottsdale) a
kid lost 3 fingers on a band saw and they were vacuumed up by the
central shop vac.

While the medics were stabilizing the kid, my son dumped the saw dust
out on the floor and recovered the fingers.

They were successfully reattached!

("Course it helped that the kid's father was a surgeon ;-)

Yep, though I cut these receptacle holes freehand. That's why cover
plates are larger than electrical boxes ;-)

2: Opti-visor (like mine)

I bought mine (IIRC) around 1980... love it!

3: good camera. What is it?

An old Sony Cyber-Shot 3.3 MegaPixels, DSC-S70, "macro" focus setting.

4: Sorry to hear about your son. My condolences.

Thanks!

Ouch! I remember being annoyed that the machine shop I visited while working
in college required you to wear jeans and a long sleeve shirt, even if it was
100 degrees out... maybe they were onto something there...

I never did take issue with using a push stick whenever you were getting close
to finishing the cut through your material on a band or table saw...

I saw this website which was interesting, though I am not sure that I would
buy one, unless the false-alarm rate is practically zero it could get
pretty expensive.

Although I think it is a nice piece of brute force engineering, I think they
spend too much time going on about how much you will get sued for if you
don't buy their thing. The videos are pretty big downloads also.

Pretty impressive!

I'm thinking an exceedingly hard, sharp, tough bit, (case-hardened
carbide?) running at insane speeds, could dig through tile, but
yes, I'd want some substantial safety glasses for when it snaps. =:-O

Thanks!

I learned all that crap at the age of about 8, because Dad inherited
Grandpa's ShopSmith.

I came home from school one day (about 5th grade or so) to find that my
brother (about 10th grade) had cut his finger on the table saw and was
on the way to the hospital.

They saved the finger.

Cheers!

For tile, the sell a solid tungsten carbide 1/4 inch diamond cut router
bit. It walks right through normal clay based tile, such as is typically
seen in bathrooms (eg. 4 inch square clay bisque tile). It would have a
problem with porcelain floor tile, as it is much harder, but it would still
cut it...slowly. You have to let these bits cut at their own rate. Forcing
them is a recipe for instant destruction of the bit.

They're competing in an old, mature commodirty market with pretty small
margin, so it's pretty hard to convince people to buy new shop equipment
unless you can convince them of a significant benefit -- not getting sued
for millions of dollars is perhaps the only thing many shop owners would
listen to!

The videos are pretty big downloads also.

Agreed, they should have a "dial up" option.

They use diamond router bits for edging granite, once saw
a guy using one with a garden hose to supply cooling and
lubrication. Also seen a guy successfully route the edges
on a 4 inch thick aluminium slab with a handheld router:
very, very slowly and with lots of lubrication.

Hi Mark,

Not quite the same thing. The router bit I was talking about
is solid tungsten carbide, and is cut with diamond shaped
facets. It is sort of like a round version of a bastard cut
file.

The granite guy was certainly using a diamond abrasive cutting
tool. Granite eats tools for breakfast.

Routers have a tendency to self feed, and when they take a big bite,
they want to take another, and another, and pretty soon, they have
jerked their way out of your hands. They are best used with soft
materials, and using tools that can only take a very small bite with
each revolution.

datasheets I don't see a problem. Also some solenoids used on
AC will actually get HOTTER if the plunger doesnt pull in.

old 500 series,too bad they aren't made any more,they were handy
for dummy loads.) Yes.
