- I can think of three likely reasons you aren't getting good results:
-
- 1) Dull blade (You may be able to inprove this a little with a whetstone
- but usually blades used by non-pros get nicked from being dropped
- and such.)
-
- 2) Wrong wire, 22-26 AWG PIC or PVC wire works best. Broadcasters
- will often use them for stranded wire and 20 ga wire.
-
- 3) You are aware that the blade has two ends, one of which cuts and
- terminates, and the other which just terminates.
-
- The inpact is supposed to be adjustable, though I've never noticed a
- difference from adjusting this control.

- If you are going to use ethernet, I would opt for the 110 if you can
- borrow the tools to install them. I am assuming you are familar with
- the 66 blocks. The 110 blocks were developed by AT&T as part of their
- Premise Distribution System (PDS). 110 Blocks are composed of two
- parts, a wiring block built in units of four strips, each holding 25
- pair.
-
- The wiring is positioned on the wiring block and a connector block is
- punched down of top of them. Connector blocks are available with
- capacities of two, three, four, and five pair, and contain the actual
- insulation displacement clips. The building wiring or cable from a PBX
- or other equipiment goes under the blocks and jumpers are run on top
- of the connector blocks. Both the wiring block and the connector
- block are color coded.

-
- 110 Blocks are designed for 22-26 AWG PIC and PVC wire. In this
- respect they are not as versatile as 66 blocks. They are however,
- supposed to be better for high speed data and use much less space.
-
- Northen Telecom has a similar product called BIX.
