Might add; Probably an AWS test (American Welding Society). Some tests give you a lot of range in what you can weld afterwards and some do not. If you have a choice, take one that gives you a wider range before you have to take another test. Usually a difficult position will cover easier ones so ove...

There are many many different certifications, so ASAP, determine which one you are doing - that should dictate the rod type, metal thickness, position and the other variables. Get a copy of the structural code if possible - it should list the tests. Each industry has multiple certifications and most...

Mothballs are reputed to be a pest deterrent also.

I can spare six. How about $5 each plus $5 for shipping

Got a number of new USA Nicholson 18" blades - 1 1/4" wide, .062 thick, and 6 tpi. I am using them in a old Mavel draw cut saw that takes a 17" blade - I cut 1" off of the end with an angle grinder and punch a new hole. Will these work?

you will need to come up with relative ranking as well.

I have seen something similar that was used to set exact lengths on connection rods. Possibly to set up linkages.

Might catch someone sleeping! - but not Harold!

Do you have any change gear options? Even if you have a quick change gear box, frequently they are driven by an exposed pair of gears on the left/outer end. Those gears could be swapped/replaced to give alternate pitches.

True, I recently got a model 4F on ebay and was able to find all of the collets there too. Travers, among others, sells new collets. Tappers are a joy to have for the right project - just finished 30 special nuts with a 1/2-13 thread in 3/8" thick steel bar. Took longer to lay out than to drill and ...

HF usually makes a sizzling sound, sort of like frying eggs, so if you can turn it on, listen.

I would have to go with Marv; without knowing the twist/error relationship, the rest is just an exercise. Might turn a part with a measured twist, straighten the lathe, and cut a new part and compare the error. Leveling the bed is really just a convenience; the lathe could be mounted at a 90 stickin...
