I picked up a barely used Jet JBM-5 mortising machine for 200 bucks!
Not the best score I've ever achieved, but it's a pretty good deal.
I've been wanting one for a while because I'm doing more and more
projects with mortise and tenon joints, so I'm looking forward to
working with it.

Maybe if I get to doing a lot of M&T projects, this will whet my
appetite for a Domino machine.Â* I'm pretty sure I can sell this Jet
for at least what I paid for it.

There is nothing like mortise and tennon joinery.Â* It is a big step
towards quality construction.

I've done quite a few pieces with M&T and really like it, but it's
always been a slower-than-need-be process and I usually end up winging
it.Â* I look forward to discovering if this speeds up the process or not.

If you were hand cutting with chisels, it will be faster.



I bought a similar bench top Delta mortiser about 15 years ago.Â* I can
count on one hand how many times I used it.

I'm entirely open to the idea that I may not get much use out of it,
which would probably mean I had since moved on to a Domino.Â*Â* :-)

Something to consider. When I bought my Domino, when they were
initially introduced, I hoped that I would use it much more often than
the mortiser. That was about 10 years ago.

Now, If you want to get more into building nice furniture with strong
joints and no pocket hole screws... ;~) Think about your first 5~10
mortises that you are not just playing around with but on a real
project. Now consider that I am on my 3rd box of 1,800 replacement 5mm
Dominoes plus the initial 600 that came with the kit. And I am well
into a case of 6mm Dominoes too. Double all those Dominos and you have
both mating mortises. Each mortise with the Domino takes about 3
seconds..... If you have ever used a plate joiner/biscuit cutter, it is
exactly that fast, but dead on accurate.
MY Domino has paid for itself countless times in time saved.




A very cool machine but it and the chisels must be in tip top
condition to give you good results and to enjoy using the machine.
Mortises less than 3/8" can be tricky and you should proceed with
caution to avoid clogging and breaking the inner bit.



In the mean time I'll have some fun with it.


Cool!

If you have not used one much you are going to want to be sure the
chisels have a polished mirror finish.Â* There is a lot of friction as
they cut the wood and like your bench chisels, a mirror finish is
desired.Â* There is also a cone shaped stone for your drill to work the
end of the chisel end.

The 3 chisels that came with it are super-duper sharp.
Replacements aren't that much, but I'll look into that stone.


They do need to have a mirror finish on the 4 outside sides, just like
the back side of a chisel. It will make a world of difference in the
effort you put into plunging the chisel.and bit.
