That was an 8” SE/Prism/Parallel/level.

It is designed to be a handy, versatile, and competent tool. It has been very popular. I built up a stock of them which I thought would last for...

It might be true that it was available to Monarch prior to 1943, but it might not have been available due to rationing and prioritization until after WW2. Monarch may not have adopted it for some...

I am not trying to make a federal case about this. But, I guess what you mean is that you have seen round dial lathes that seemed to have ductile iron apron levers. I suppose it is plausible that...

I think the plastic/foam cases would be great for travel. Bombproof as said.

But are you traveling? My guess is not based on the plastic “case” you are presently using. This set and case don’t...

This is the unit I bought. Incidentally, you can orient the impactor vertically, at 45, 90,...

I have a defibrillator/ standby pacer. My unit will make humming sound if it encounters a large magnetic field. It will not function if it is turned off by a magnet. I made mine hum a couple...

How could that be since the EE was introduced in 1939 and ductile was not invented until 1943 with the patent application filed Oct 25 1943? That’s after my lathe was shipped.

Sure you can quote me... for all that is worth. ;-)

I have a Leeb (200 dollars more or less) and a Wilson Junior with calibration coupons. I test cast iron castings several times per week.

I routinely cut samples with an an angle grinder. You...

What year apron?

The ball end on my original EE handle is roundish but not as und as a ball bearing.

Making it from ductile iron would solve the problem of breakage. Ductile iron was invented in 1943. How long...

I have a 1943 EE that I snapped the head of the locking lever off. This occured as the lever will snap back If I fail to fully lock it as I extend the lever. At some parts of the bed I have to be...

Ya, that is why in a couple of the above posts turning it it temporarily into a "dumbbell" with slide-on fist-size lumps of steel or iron and then insulating the lumps with ceramic wool is thought to...

Maybe I am misunderstanding what you are saying. I am suggesting chunks of iron or steel slipped onto the crank ends and wrapping the chinks in ceramic wool If yo are saying they will turn black in...

Sounds like an interesting approach. I’d think when the assembly you suggested was pulled from the oven, wrapping the “dumbbell” ends in ceramic wool would enhance the mass effect you cleverly...

It may also be useful to remember that the profile of the thread cut or ground into the spigots on the crank need to be reasonably close to ideal, but do not have to be extremely close to “perfect”...

I have been working diligently to get my various straight edges back in stock. I have enough on the shelf that I can resume sales of 18’s. The eBay price is 197.50. PM members who buy direct from...

Well, there is well thought theory and there is practice. I knew the only way to answer the question satifactorily would be actual hands-on testing.

I just went out and quickly hardened a 1"...

You could harden and temper the whole works. Then wrap wet rags on the crank leaving just the spigot exposed. Heat the spigot to reduce its hardness to maybe Rc 45 or so by heating the spigot to 1200...

The good quality American-made hand crimp tool I bought came with a crimp test guage to check that the sleeve is properly crimped to size. I guess the same test could be done with a caliper. But, I...

And get a 30” or so piece of 2x2 or bar stock etc to jam into the vertical track as a safety device. Attach it to the machine with a lanyard and paint it orange. That may be too crude to pass OSHA...

BTW, you said before you could not load pics. Looks like you did just fine. Adds a lot to understanding your repair problem. Way to go.

I am sorry, but listening to unqualified and uninformed people here give completely indefensible medical advice advice equivalent to “ buggered up head bolt hole threads? Well go to Kmart and get a...

Having worked with aluminum/steel combinations in a salt water environment I think you are spot-on to be concerned about galvanic corrosion. I would spray a coat of zinc paint on the table and the...

From what I have been reading the new variant is perhaps 20 to 50 percent more transmissible. I don’t think it is orders of magnitude more infectious. Similar precautions with people hopefully...
