Broaching is the way you cut the keyway in a shaft hole. It takes a

the slot.

My lathe is a rebuilt and tricked out Southbend 10K. It will swing
10" over
the bead which means it can face a 10" cylinder but only about 7"
down the
side. The Rong Fu is a square columed 3 HP mill/drill which is big
enough
to do anything I need. Together they might be worth $3K. The
problem is
the tooling. Between mill bits, turning bits, tool holders, rotary
tables,
vices, collets, V blocks, and a hundred other required parts over the
years
I probably have spent over $10K. That doesn't count the MIG welder,
the TIG
welder, the plasma cutter, drill press, assorted vice grips or any of
the
woodworking machines and tools. It took 20 years to accumulate all
that
stuff but I could probably buy everything in the Harken catalog for
what I
have in tools.

Even worse, there is not enough room in the back stateroom to put it
all!

Glen,

Pardon my ignorance, but what is 'broaching' ?

So many toys, uhhh tools, so little time :-)

What criteria led you to the Southbend and the Rong Fu ?

Any recommended vendor(s) for such ?

Appreciatively,
Courtney

With all custom machine work the setup time is 90% of the cost.
Once
you
get the setup done you can machine 10 parts for only twice the
price of
a
one off.

I am running a Southbend 10K lathe, Rong Fu mill and lots of
welding,
grinding and polishing equipment. I machine parts for the
equipment I
design myself and a few replacement items but usually the OEM
parts
require
tooling that I don't have and so much setup time that it is
cheaper to
just
buy the part. Lewmar could probably machine and assemble 20
windlasses
it
the time it took me to turn, bore, broach and polish one drum and
the
broach
would probably cost as much as an OEM drum. OTOH, if you are a
tool
junkie
like me it is a great excuse to buy more tools. :-)

One of my machinists recently bought a Haas CNC mill and is looking for
work for it. He also has the use of our shop with two ENCO digital
mills, a couple of lathes, grinder, etc. We could do nickel plating
and Cu plating if necessary. You can get our e-mail off our web site
at:

You can design, price and order anything custom online. What will they think
of next?

Many mechanical parts cost a small fortune to replace.

I'm wondering if any members of this group have power equipment such as
lathes, milling machines, cutters, formers, molders, etc., [other than
welding], that they are successfully using to modify, repair, and
duplicate... pieces of varying materials.

If yes, what are you using and to do what ?

I recently ran into the problem of replacing/repairing a windlass rope
drum and it's unreasonably expensive and I'm motivated to unhitch from
vendors and suppliers to that extent possible and reasonable, which I know
varies from person to person.

Appreciatively,
Courtney

Where is he located ?

Gratefully,

You might try this guy. He has a specialty one-man machine shop and
last time I checked was very reasonable. Also willing and capable to
take on 'weird' object projects(grin)
