I am using a rotozip-type tool with a 3/8 rabetting bit
on a 1/4 shank and collet.
As might be expected, this tool has its prob.'s from
being too lightweight to do much. The bit is cheap too
because this is all trial work for me on a first
from-scratch project.
So before I make any more pieces just suitable
to roast weenies over, my first question is this:
I'm using the tool counter-clockwise in the
prescribed manner but I'm getting way too much
tearout on the edges to make these baffle cuts worth
finishing off. Also there's some smoke involved and the
bit edges have blackened.
The material is birch ply from the local home Depot.
I have a few blanks left to get this technique down.
How can I eliminate the tearout? Is it just a dull bit or
something to do with grain direction? Or is it a problem
handling the tool itself? A couple of my samples turned
out pretty good with rabbets front side and chamfers on the
rear. But I can't get any consistency. One practice piece
looks like a daisy from what looks like hitting a knot. :-|
Well enough of that for today. I have a filing
cabinet to put together of the "Insert Flap "A" and
Throw It Away" type. :-)
