Default Mortising machine--what am I doing wrong??!

I'm going to go with a dull bit. Not the spur that
severs the grain at the outside of the hole, but the
edge that peels off the wood for the hole. If dull
it would tear out chunks instead. Chunks can
clog things up whereas shavings won't.


Upon further inspection, if I had to guess, I'd say this is the
problem. Nothing about these bits is sharp. Not one edge. Too, the
machining marks left behind are a disgrace. The chisels themselves
seem okay, but again, not great.

When I get home from work this evening, I'm going to chuck-up just the
bit and leave the chisel off altogether and see how far I get.


If necessary file the edge then refine with
slip stones. The sharper that edge the easier
the drilling. The easier the drilling, the
easier it is for the chisel to do its job.

As for the Forty Cent Method for setting the
bit to chisel spacing - thank the Fisch rep.
I just did the illustration and put it up on
my site.


Which is the hard part. Hell, the Fisch rep just told a story! Again,
thanks for all the good info on your site...I mine that on a regular
basis.
