 Fear of tools
This is a good subject for my first post.
My favorite tool story is the sort of user who says, "No worries mate, I've been woodworking for 30 years and I still have all eight fingers."
Well I've been doing it for quite a bit less time and am still ponering my first router.
I've been doing jobs with a smaller tool which takes router bits with 1/4 shanks.
It came as a kit from the Menard's home store in US.
I've been able to use this gizmo with zip bits to do cut offs, chamfers and
free hand flush trims and rabbets.
This is all in the speaker building hobby.
The topic of concern is making flush trim for oddly squate shaped
audio speakers. I've done this free hand on the surface. But the
accurate procedure is to use the flush trim bit mounted in a table,
make the pattern and then do the additional steps to get the jig made.
This has been covered in a thread I started at diy audio forums called
"flush mounting drivers, the whole story." The thread is made for both round and square speakers and also the process of making round driver holes.
When using the table setup, the original the piece is mounted to stock and the edge of the piece (metal flange) is used to get the pattern.
I've looked through the info here and see illustrations of the procedure.
There's also a source in a speaker magazine called audioXpress.
My question is on guiding the work to the mandrel/turning bit. I've seen here where hold downs are used to keep hands away from blades in close corner work.
What is the preferred method for this? |
