Oh yeah, the T handle is a great thing - especially those that have a strong spring and a ball or similar design to give resistance to the sliding of the rod... I don`t like a free floating rod, but a rod that stays in place during spinning or even when you extend it out for max torque - oh yeah, those are good! A good wrench is great, but generally, a socket and a breaker bar or a socket and a T-handle are so much more versatile and effective(and less abusive towards both the nut(in majority of cases) and the operator...) in most cases... Also, imbus sockets, the large ones make for excellent custom keys and wrenches when you have access to a lathe and/or a mill - depending on what you need to make outta them... The triple-square sockets also fit the square headed bolts on machines and machine components/accessories(vises, toolposts and similar) - being just a star made by three overlapping but offset squares... That make a long triple-square socket with a long extension and a t-handle an ideal vice tightening mechanism, unlike those dreck cnc solutions that people buy into... My Rohm mill-vise nicely fits the long 18 triplesq. socket... Best regards! Steuss

People don't talk about steady rests because they are obsessed with the spindle bore of a lathe. They buy oversize lathes that allow them to shove 120mm shafts through the headstock. Unfortunately they don't reallise they loose control of the shaft. The other issue is the lathe is then, generally to big for their more typical work so it sits there underutilized taking up capital and consuming opex. Thanks for sharing.

@@dolata000 roughly 0.005” total on the indicator in any set up would be about my limit. Usually we can get things around the 0.003” with rollers set at 4-6’. Depends a bit on diameter, length and also where the bend is. Also bearing spacing and clearance, but not the biggest factor. Lots of shaft come in with over 0.020” bend and the customers say that it wasn’t really noticeable. Usually the proper blades get dinged and cause the most vibration.

The burnishing tool could benefit from having the moving parts enclosed to keep bits from entering where the ball rolls on the bearing. It could hold a reservoir of oil in the area.
@OgiveBCАй бұрын
I haven’t had any trouble with debris, the burnishing process is done after the turning process so the part should be clean. If needed you could give it a sweep, wipe or quick shot with compressed air. As to the oil requirements, I have found the tool to work well with almost anything from cutting oil, hydraulic oil, spray lubricants and also water soluble flood coolant. I have also used the tool dry and it works nearly as well. I think “a little dab will do ya” is all it needs, I was applying likely much more than oil than needed in this video. Thanks for commenting. If you have time please give Jim a thumbs up on his channel.

Some nice information you've gathered here. Does burnishing alter the size of the diameter? I've never done any burnishing work myself but I'd imagine it would alter the size, but not as expected. I'd guess that 15 thou you've moved in by isn't actually reducing the shaft diameter by that amount?
@OgiveBC3 ай бұрын
In my case with just the one pass of the burnishing tool, moved in 0.0075” on the radius, a.k.a. 0.015” on the diameter, I was getting fairly repeatable results of 0.0005” (half a thousandth) reduction in the diameter of the part.

As far as deep slotting goes we pretty much run whatever is handy, 2,3,4 flute etc. I find you have to run 4 flute shallower otherwise they blow up recutting chips, you can definitely tell a difference running two flute. I would run a fine tooth roughing end mill with air or coolant blast to clear chips and finish with a standard end mill. Since I started running CNC I run 4 flute full depth with a 10% step over & two flute for slotting up to 1/2D. That is pretty much max for full dia slotting for any endmill. I hate 316.

Get a roughing carbide endmill. Guhring makes a series with Firex coating that I really like. Then just have at least air blast on it, and do your slots in incremental step downs, 50-100 thou at a time depending on material and diameter. Once it's all roughed out, come back with a finishing endmill to make it nice and bring it to size.
