- The extension cord wire sounds inexpensive and may be the best answer,
- but DELTA has come up with a solution, also! I think it is new, at least
- I had not seen it before in DELTA's catalog, etc.
-
- DELTA has come up with a solution to the switch, a solution to their
- safety guard, and several other solutions. The brochure I saw shows
- that they are now producing a safety guard which is attached to the right
- side of the table (assuming that you are facing the saw). This safety
- guard is a tubular affair which extends up in the air and across the
- table to reach and cover the blade. It is advertised to be used with
- the dado and other blades without having to be removed. It has anti-kick
- back devices which if they must be removed may be stored in the "arm" which
- reaches across the table from right to center. The "arm" has a place for
- a lamp attachment and last but not least...the arm has the switch in
- it! So, the switch ends up like the above "extension cord" apparatus....
- except it appears to be much more stable.
-
- The price was not quoted, but it seems to be the answer to the safety
- guard, switch, etc. It was shown on several of DELTA's saws including
- the Contractor's Saw, the Unisaw, and others.
-
- They didn't say what one should do with the original safety guard which
- comes with most brands of saws including DELTA, Powermatic, etc. BUT,
- I would like to suggest what they might do with it! <grin>
