A 16.5" flywheel with two v-belt tracks. Put on a new set of belts with insignia labels. Lined up the reference labels and turned the machine on. After a few seconds stopped the machine and reference marks are off. The two tracks were not exactly matching. The belt height on one side was about... -

Leveling a solid bed lathe compared to a split-bed V type.
Is it less of a concern to hlvh owners?I'm ready to take it seriously. In other words... another PITA obstruction to real goals.

Where would you buy a welding helmet today?
And probably the answers change every 6 months. Or stay with what a local welding supply sells. I wrote down brand/model and searched. Not one hit. But that was 10 years ago. I need a quality auto-darkening helmet, as long as there is no dramatic art printed on it. And newer isn't better. What...- rons

Which insert for this boring bar. The number is CCxx 32.5x. So many choices?

Attaching rings to a 1.5" bar by just: heat ring, locate ring on bar, cool?
Ring rings are 304 SS OD 1.625, ID 1.49X, width = 0.375.. The bar is OD 1.5 303. What are the limits of the ring's ID of 1.49X, X meaning 9, 8, etc. How much temperature is going to expand how much metal? Probably could heat up a few pieces and measure but I ask for a more scientific approach... -

What is this welded device?
There one 1.865 OD tube inside a 2.9 OD tube. There are two flows. Lengthwise and within the enclosed chamber between the two tubes. One fluid can transfer heat to another. It was something laying about from surplus. Wondering about it before it gets cut down. Need the tube inside for an antenna...- rons

Which dial caliper to trust? (This was worded as "dial indicator" before. In the end a dial is a dial)
Out of four calipers for example: Two Starrett 120As read .014 slightly over the line but not at .01425. One caliper is very lightly used and the other is my companion. One import digital readout caliper says .0145, and my Mitutoyo Limited Edition almost never used says .0145. Looks like the... -

VFD store or outlet suggestion. 10Hp .
I know it's been asked before. But the last few years might have changed some things. 230V single phase in and 230 three phase out. Probably bigger than a show box and smaller than a bread basket.- rons

My Kunz 112 was not working good enough because the holes for the bottom pins allowed a slight wobble. Especially with those thick blades. Years ago The alteration with 1/4-28 screws on each side made everything tight and the tool worked much better. This plane kit has a rough casting and all...- rons

OT: Unaccounted for purchases on credit card accounts.
Happened to me. Last year I noticed about 5 amounts. Like $20, $15, $10. Totaled to around $30. The amounts were even, like $20.000. Easy to spot on a statement. Called my bank. Their policy is to reimburse the amounts and then investigate. So why do I post this? A few months ago I heard on...
