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. :-)

....the Roto-zip away. Hopefully you bought it at the Depot as well.In which case you can return it and the accessories and get a 40 or 50 dollar Ryobi plunge router which will do all you need.
If not possible, hold on for dear life and make several passes that are maybe 1/4" of the rabbett at a time. Then make the finish pass and finally, go clockwise, known as a "climb cut" to finish the edges.
The Roto and Dremel tools are for making outlet cuts in drywall and thin sheet metal. Also OK for polishing and small grinding. Everything else is wishful thinking.

Gee, they work so well in the ads.... [message #29188 is a reply to message #29187] Sun, 01 August 2004 20:55 Go to previous messageGo to next message

That's a good tip on back-cutting clockwise. Was wondering if I
was using too much pressure laterally too.


The machine has got a good enough workout that returning it
would be real problematic. There's still a laminate gizmo
to play with for flush trim and a circle cutter. The whole
shebang ony cost $30... not including the standard router bits
I bought. I have a diamond stone... may I can touch up the bit
and get the -- melted glue or whatever black crud is on it.

File cabinet is upright. Drawers not done yet-- too hot here.

Bwhahahahahaha!


No ads for this one-- it's the Tool Shop brand packaged
for Menards.


I have this thing set up in a spare room where I live.


If I got _real tools_ management might blow a gasket. As it
is I do my couple of passes when the parking lot is empty.
I'm like Bob Brines who also practices the craft in an apartment.

On drywall, that is- wonderful for making electrical box cut-outs. If you're going to do any serious routing here's the skinny: Don't bother with less than 2 horsepower, go 1/2" collet size and run only carbide bits. Burning comes from overheating the workpiece and that happens when the bit is cutting too slow; you either need more power or less cutting depth so that you can keep the bit moving at a proper pace. Like all tools a nice one is a joy to work with, a cheap one is not worth having.

I think Mr. Epstein also had some help with the
routing stuff so here is my update on what I learned.


First I sharpened my bets on a simple kitchen knife
diamond stone... it is getting pretty worn down anyway.


Then I did incremental cuts which improveds things
immensely.


The peduliar thing I noticed was that the cut would
consistently be uneven-- one side higher than another.
It must have been my technique so I just worked
from the opposite side of the piece so the pressure
was evened out.


Result: a smooth even cut which I was able to edge
sand to get the tear-out smoothed.


No smoke this time. ;-)
