repairing/reproducing parts ?

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. :-) -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

Mac,
Thanks so much. For me, at least for now, probably the way to go, if I can shoe horn in my needs to fit his program. A great idea in any case. Hope he succeeds, wildly :-) Cordially, Courtney Mac wrote: On Mon, 06 Dec 2004 12:57:20 -0500, Courtney Thomas wrote: Many mechanical parts cost a small fortune to replace.

Thanks William. I'll look into it. Probably the easiest quickest for
now, IF I can find anyone in my locale. Cordially, Courtney William R.

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 ?

Didereaux,
I put him in my file and 'preciate the information. Where is he located ?

Broaching is the way you cut the keyway in a shaft hole. It takes a slotted
bushing the size of the hole and a broach, a rectangual tapered rod with teeth on one side. You press the rod through the hole and it gradually cuts 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! :-) -- Glenn Ashmore "Courtney Thomas" wrote in message ... Glen, Pardon my ignorance, but what is 'broaching' ?
