wedge table/hardiebacker bat cutting

updated tue 1 may 07

 

Angela Davis on fri 27 apr 07


Hi Paul,

My husband cut my wonderful Hardiboard
bats with a scroll saw and circle jig. 14 inch bats cost
a bit over $1 each. He also made a jig for the drill press
for the pin holes.

I read later that someone drilled the pin holes in a square
of the board , put it on the wheel, then used the box cutter like
a phonograph needle to scribe the circle. I want to try that
next time, sounds like fun.

One thing about cutting with a saw, there will be lots of choking dust.
Wear protection, it has to be horrible for the lungs.

Sorry for being so late to reply. The listserv "Kicked me out of Ramshead
Pub" last week, and I wasn't told. Hmph! I wasn't doing the fan dance with a
boa or anything (that I can recall ).

Angela: Wearing a mask, you will find that an angle grinder, held like the
scribe you describe works better for cutting completely round circles as the
wheel spins. Be careful though, have the wheel rotating away from you, wear
a mask, and do it outdoors if possible. The direction of the wheel of the
grinder and the spinning bat-to-be should be opposite of each other. The
noise and dust are tremendous, but the results are far superior to cutting
by hand or by box cutter. No jaggedy edges to rip your wrists. Been there,
done that, ask me to show you the scars.
Best,
Wayne Seidl

Thank you Wayne, I'll let "Tool Guy Tom" wield
the angle grinder, well masked and outdoors.

I still want to try the phonograph method. I'm thinking I would have to
score
the backer board out from the scribed circle to break it away.
I very well remember the dust created and am not anxious to experience
it again. I wonder if wetting the board would help keep it down?

Wondering in Homosassa if the (that I can recall) part is what got
you kicked out of the Pub.

Angela:
The wetting of the board is a good idea, but with the angle grinder;
having the bat-to-be rotating at a good clip
on the wheel while cutting (round and round she goes, you get the idea)
will allow the grinder to eventually cut right through the bat. No
need for further scribing or fiddling with it. In this case, the wheel
of the angle grinder acts like the needle on the phonograph (and about
now, all the youngsters are going "what's a phonograph? For you
young-uns, think "laser beam on a CD")

As far as the boa, I don't somehow think so. Mel pointed out that
periodically, people get "flushed"
from the system. I guess it was just my turn.

And for the rest of you on the list, (OT here),
this lady (Angela) makes THE most AWESOME Homosassa hot sauce. You
should really buy and try a bottle or twelve.
It's JUST what I needed to complete my Pad Thai. Gave that hint of
heat, without turning us into "fire-breathing potters".
(We'll leave that to the kiln )
Great stuff, my dear. You should be proud.
Best,
Wayne Seidl

Angela,

Wayne is a peach, but save your lungs from all the extra dust produced
with an angle grinder. Just draw circles with a marker and cut out
with a tile blade on your jigsaw. I bet the wheels on the grinder are
going to produce a prodigious amount of dust compared to a jigsaw with
the proper blade. I had no problem cutting my with a jigsaw. Do it
outside for sure and wear your P100 mask. Don't forget that you are
using electric power tools, so go easy on the water if you do use any.

If you use your wheel to help cut out, I'd go with the scoring and
snapping method like you said. As for dressing up the edges, I used a
sureform tool to bevel them but I bet you could even use some
sandpaper. You could for sure use water to cut down on the dust with
this method.

Thanks to Wayne and Taylor for help and
concern. I plan to buy a sheet of backer board and
report how it worked out.

I have an 18 inch bat made from 1/2 inch stock I thought
I might use for platters. Turns out I use it for everything
but throwing.

It's a great place to dry greenware , turns a 5 gallon bucket into a quick
work table,
is a huge area to de-water my piles of reclaim on and is the best portable
wedging surface I've found.

I loaned it to Yosuke Koizumi when he did his throwing demonstration at
our high school and he was very impressed with it's usefulness as a wedging
board.

So as soon as I get time I'll get to work on the backer board bat
making.

In sunny, dry Homosassa, which "ain't all bad" considering my studio is open
on all
sides.

Thank you for the hot sauce compliment Wayne, happy you are enjoying it.
My 5 year old habenero "tree" bit the dust this year but I have a new crop
coming
on in the wings. It was over 7 feet high with a 3 inch diameter trunk. I
had to
use a ladder to pick them.
