WTB older drill press in the Seattle area
Looking for an older drill press of the sort shown in the illustration. Doesn't have to be in pristine condition. Should be a full height floor model with a large cast iron table and a crank to raise and lower the table. Could be a 15, 17, or 20 inch model, with step pulleys or variable speed...- Mikel Levy

Straight Cut Knurling Problem and Plans For A Bigger Lathe (Colchester Master 2500)
Look up the cut knurling instructions from Zeus and others. The initial setup for cut knurling is quite finicky. If you are cutting a knurl in the middle of a part, you will need to cut a groove in front of the knurled section at least as deep as the full knurl depth and chamfer the left edge of...- Mikel Levy

Is my Hitachi VFD toast?
JST--thanks for your reply. No symptoms--just suddenly stopped working, no lights, no nothing. Remote fwd/off/rev switch plus potentiometer for speed control. Of course, one of the first things I did was check the shop circuit breakers--all OK there. What I didn't do, until after I posted this...- Mikel Levy

Is my Hitachi VFD toast?
So I was just starting a cut on my lathe when the Hitachi WJ200-022SF VFD/inverter went dead. I unplugged it, waited a minute, then plugged it back in with no result. It's a 2.2KW model with 220V single phase input and 220V three phase output, and drives a 3 horsepower motor. Been working fine...- Mikel Levy

What is the purpose of an extended spindle on a drill press?
This isn't something I've given much thought to in the past, but now that I'm looking to replace my drill press I was wondering if there's any advantage (or disadvantage) to a drill press with an extended spindle. Thanks for any information that might enlighten me.- Mikel Levy

Looking for a floor model variable-speed drill press along the lines of the one shown in the picture, preferably within a couple of hour's drive of Seattle. Not particular as to size; should have a crank-operated table with thru-slots or t-slots, and quill travel of at least 4 inches. Best way...- Mikel Levy

Question on Harrison AA/Harrison VS330TR variable speed drive
Do an internet search and you will find some good info about the variator drive in the Colchester Chipmaster/Harrison 10AA lathes. Apparently many of the variators in these lathes have failed. Whether this is simply due to long-term wear or a lack of robustness in the design is anybody's guess...- Mikel Levy

Problem with drilling
This forum (and the world) is a better place when we celebrate our common interest (in this case, machining) and leave our preconceived notions and prejudices at the door. Hamidjahan-- If you can provide more information about the purpose and function of the part you are making, people...- Mikel Levy

Carriage Stops -- is there a standard way size?
As others have suggested, just make one. I made the one pictured from aluminum, using a bandsaw and a file (I don't have a milling machine). A rod screws into the side of the carriage stop clamp to act as a hard stop, and stores in the clamp itself when I want to use the dial indicator instead...- Mikel Levy

Best non traditional Materials for machining Jewelry out of
I showed my daughter how to make earrings from copper plumbing pipe. She annealed a short section with a propane torch, cut it open, flattened it, cut out the shape and hammered it, shined it up, selectively oxidized it with the torch, then sprayed it with a clear protective coating.- Mikel Levy

Need some Multifix tool holder advice
I guess it's a quirk of mine, but I hate having to readjust the tool cutting edge back to center height when I swap out tools in a holder--ergo the large number of holders. The lathe is a Colchester Chipmaster, 11" swing. Currently using an Aloris-style AXA-sized system, which works fine...- Mikel Levy
