Re: Lead-Free Plumbing Solder: is it Greenie Garbage?

Lead-free plumbing solder is silver solder with the smallest possible amount of silver (to keep it cheap) and a few other low cost metals added to the tin. The supplied flux is probably something considered safe in California (and therefor useless). Treat the stuff like silver solder. Better yet, us...

Re: Wacking the Morse taper out of the spindle

A morse taper is very slight and doesn't need to be drawn in very hard to hold. A Morse taper is a self-holding taper. One that fits well does not need to be drawn in very hard to need quite a bit of force to get out. That's why they have tangs and why Morse taper drill press spindles have slots fo...

What personal safety equipment would have been readily available to a foundry man in 1906 ??
Boots, long trousers, and overalls. All of which those guys are wearing.

Re: Phase converter questions

Yes it does. I only have a rotary converter in my shop just for the hoist. I use vfd's for everything else. My experience with static converters has not been good. The ones that I have had, ran for about a year and then exploded, literally! I don't need that to clear my rear end while machining! Ji...

Re: Phase converter questions

You can run any motor or motors up to the rating of the phase converter. If the phase converter is rated for 10Hp and you want to run a 1/2Hp, 3ph motor you can. It's just a little overkill on the phase converter side, but I do it all the time with a hoist. Jim B That depends on the type of convert...

I would think that 6061 in a T6 condition would do the job satisfactorily, and it's readily available.

A direct comparison of 4032 and 6061:

Re: Lathe setup device

I think that most of the lasers that we civilians have access to have too wide a beam to be used for something this precise. I use Earlgo's method. It definitely gets me to better than the width of the typical laser I can afford. I once tried to use a carpentry laser to do a wheel alignment and fou...

Re: I do not understand cams

Any flat cam follower large enough not to dig in will follow the same profile. The excess diameter simply never touches the cam. Visualize this and then replace the cam follower with an end mill.

Re: Lathe setup device

I came up with an idea that could help in setting up cutting tool bits to the lathe center. It would use a laser. Has anyone made such a device or has one been marketed? Mr.Ron from South Mississippi Top Google lathe laser alignment. Lots of very expensive industrial products but also lots of DIY a...

Re: Vise, Vise, Baby

I have a Columbian D45: I didn't realize that it's special. It's just what I picked up at an auction about 25 years ago when I needed a vise. I also inherited a very old Oswego 13 1/2 B.

Re: Vise, Vise, Baby

I do not like the movable front jaw type. I like the rear jaw moving on dovetails like the link. (if the link works). I had one in Italy and the jaws close parallel on all axis, you can hold a pin in a corner an file the top lengthwise. What I have is a $50 HF that I do not mind abusing as press or...
