Danny, Not trying to save a buck, I already have one! :wink: I use Carbide indexable tooling exclusively for all of my turning as I have the HP, speed (could always use more), rigidity, and flood cooling to do so with very good results. I have tool holders and inserts for every occasion I've encount...

CarlD, No disagreement here whatsoever! Didn't read your post as stating either method was correct or incorrect. I own a lathe with a 1080 rpm spindle that I've had since 1978. I recently purchased a larger and faster lathe with 2000 rpm spindle. I much prefer the new lathe. Surface speed is the nam...

Harold, There was a post on the PM forum once regarding a P&W 12" lathe for sale and it stated a 1000 rpm max spindle speed. I simply posted "1000 rpm max on a 12" lathe?" in a way of asking if it was possibly a misprint and got thoroughly flamed and immediately branded "one of those young speed dee...

I've still got bruises from posting that I actually thread with it :) ) Dave, Thanks for opening up the R&D Lab for the experiment!! Harold's post about HSS not being...

Can HSS be heated and bent?

After reading a post by Harold stating the HSS cannnot be annealed by overheating during grinding it brings up an odd question.

Can HSS be heated and bent?

Not looking for right angles, maybe 10°-15°.

Just curious,

I've used a 6" abrasive wheel on the surface grinder. Add the compound MagnaSine for compound angles and there's not a whole lot of rough grinding left to do. Just got a piece of 5/8 Cleveland HSS to make something out of.

:D

When using a vise I'll zero both sides of the jaw on X so I can work from either side or handwheel as sometimes it just works out better that way as I'm ambedextrous. Prefer left handed though. If cutting windows I'll zero both dials over a center point so cutting in both X directions without too mu...

Todd, Very good points! Although I can't speak for others, my intended purpose for placing a few "sticky's" at the top of this forum covering basic operations for reference was not with the intent of discouraging new posts or turning posters away. It was actually intended for convenience for newbies...

Bill, Since we're on the subject of backlash..... I've been monitoring this thread and don't believe I saw it mentioned, but if it was, please excuse me, but all of the methods described above will be rendered nearly meaningless if the handwheels are not turned in the correct direction when "zeroing...

In the event that I was unclear with my original suggestion, I was rererring to having three or four "sticky's" to remain at the top of THIS forum so it would be clearly visible and easy to reference without having to go anywhere else. I believe that Harold's tool grinding tips should live there reg...

I've also suggested something else in the past, but I'll mention it again for reference. Win-Win... BadDog, Please read your post and then read my suggestion in the opening post by Harold and then my subsequent post! I guess this could be considered as an example of the "research" (or lack of) prob...
