    Accufinish wheels are pretty much the same as flat plated diamond files.

    +1 on Barkeeper's Friend. That's what we use here on the Accufinish wheels and it works a treat. Also great stuff to keep the coffee pots and stainless clean.

    The best numbers I can find online are about 3900 lbs. Sounds like risky business. Hit a good bump and things will break.

    IMO, preparation is more important than the solder type. Clean pipe, clean fittings and the right flux and temperature. Full insertion.

    Rode hard and put away wet, as they say. It could be restored to near-new, but IMO there are way better places to start.

    I have better things to think about. I put it where I need to for threading and wherever I feel like for anything else, usually where it was when threading. :)

    There are only a couple good sites that cater to hobbyists, maybe fewer than that, and the traffic is much lower than PM. IMO, PM is the best machining site there is. No reason it can't stay that...

    We run one at work, an Atlas Copco I think. It's oil-less as we can't tolerate any oil, followed by a refrigerated drier. It's all been remarkably trouble-free.

    I don't let anyone near my Lindstrom 8140 cutters. Copper wire only. We have a lot of people around here that like to cut piano wire and found that Aven makes some inexpensive carbide insert cutters...

    As a curiosity, the thread wire formulas are inexact. The error is usually very small but can be significant for certain multi-start threads. W.F. Vogel worked out an exact solution in his book, The...

    How do you 'spose they certify the standards? My guess is wires plus optical for the geometry. If the geometry is off, nothing else will matter.

    If you can make money in photography, any other business should be a piece of cake. I'd certainly do a survey of who your potential customers might be and equip accordingly, not choose equipment for...

    BTW, if you happen to be a machinist, it's not rocket science to rebush a worn hole. You want to preserve the location. The info is out there if you search.

    I'd start by leveling it with an actual level. Some are quite fussy. Listen for the tick and tock intervals to be equal.

    I really like having the VFD on my surface grinder. I can convince a wheel it's something it's not and the gentle ramp start and stop insure nothing ever shifts.

    That Nicholson is the exact file I've got. I think I've got it now- the file is pushed in a straight line and corrugates only its width. You can't run at an angle as if you were breaking a long edge,...

    How do you use a corrugating file?

    As in, how exactly do you hold it and draw it across the blade to be corrugated to get the desired result?

    You might try a search for "bar bed lathe". A few rather nice ones have been made.

    It's all design and execution. Heck, I could build a nice lathe from maple and some steel plates. Good lathes have been made from heavy round rod stock. SBs use simple plain bearings yet achieve...

    Mill is set up to run something and you need to drill a hole. Need a drill press!

    I use mostly 3/8" HSS on my Logan, similar in size to the SB. I also keep 3/8" brazed tools around, and my larger boring bar takes inserts. If you look at the grinds in How to Run a Lathe, you'll...

    I'm still looking for the knob on the machine that sets the tolerance.

    The human brain has all manner of biases that make audio discussion and evaluation a futile waste of time that goes on forever. FWIW, I'm perfectly happy with an old pair of Sony MDR-V4 phones and...
