Chuck, I just went out to the shop and checked my mortiser. I'm
wondering if one of the stops is loose or the machine is not completely
locked into the jointer on one side. I found that if the mortising
transporter is not completely locked to the jointer than you can get some
slight rocking which could cause the table to move further causing the bit
to take a big bite out of the workpiece on that side.
Hope this helps.
Take care,
John Renzetti

Subject: [felder-woodworking] Using large (non-precision) bits with the
mortising attachment
I'm finding something troublesome with my new mortising attachment (rolled
up to BF7-41). After a discussion with Wolfgang, I was able to use my
18mm
& 20mm mortising bits without constantly knocking the bits loose. My
technique was wrong. I was plunging and then trying to traverse the
mortise, as the BF7-41 instruction manual says. However, Wolfgang
explained
to me that this only works with the precision (smaller than 18mm) bits.
After following his instruction to make adjacent cuts and then a clean-out
pass, I am now able to keep the bit from coming loose. (This is decidedly
a
good thing!)
HOWEVER.... I am experiencing something that concerns me. Even after
proceeding as I described above, when I move the table over to the right
side of the mortise, I am getting serious kickback at the end of the
mortise. NO kickback on the left... only on the right. It's making for
sloppy mortises on the right.
Anyone else experiencing this? Whadaheck am I doing wrong? Or is this
something I just have to live with?
Thanks,
Chuck
