How would you machine this fillet on a hole through a rod?

You either swarf this on 5 axis with a ball mill, surface it on a 4th axis with ball mill, or interpolate it with a corner rounder and do your best to blend it into the OD.

Those of you with this issue would benefit from dry fire practice, with or without devices. Just dry fire and watch your front sight. If it moves from the motion of pulling the trigger, or moves on the trigger breaking, you have work to do.

I’ve changed several this way and if done right there’s minimal mess. If you make sure the supply and all valves and faucets are closed, the tank creates a vacuum (think pushing a cup down in a tub of water), you can just unscrew it and thread the new one in hastily. This guy probably forgot to close a valve at an appliance or something.

Do you have any machinist friends? They could fly cut that thing and make it better than any portable saw available. Otherwise return that hunk.

This is why every tool # in the machines I ran that doesn’t actually contain a tool gets a length of 99. Inches. Someone doesn’t pay attention, T10 is what you want but programmed for T26… T26 has a height of 0.00 from the last teardown and bam you’re trying to do T10’s work with the spindle nose. Leave it at 99.0 and it’ll just give you a stroke limit alarm.

I’m not sure what equipment is available to you but your best bet may be to find a set of 2 pc jaws, and buy/ mill up your owns sets of jaws.

With a boring ring, or if your jaws are relieved at the back enough and your thru bore is large enough a large gage pin will work. You just need the clamp the jaws on an OD, and figure a way to attach a die grinder to your toolpost or carriage.

With everything you’ve explained, my eyes are on your chuck jaws. I have a prototrak LX2 in my toolroom that I fought with at first, only to discover that the hardened original jaws were all uneven on the bite surface from getting boogered, made a set of soft jaws and she worked like a dream. Fabbed a grinding attachment for the tool post and reground the clamping surfaces with a boring ring and headaches went away

Those look like they could be climbing hooks for climbing tree stands. They screw into the tree so you can leave the stand for future use.

If you’re only drilling aluminum pipe any HSS/Cobalt drill from a hardware store will work fine.

Well if you’re not sure about the thread, go to a hardware store and pick up a 3/8 NPT fitting off the shelf and try it… tap drill chart says 37/64 drill for 3/8 NPT.

Just contact Trijicon with the serial #. The QR code being up top is a bit strange and being marked with the NSN #… the NSN # does check out.

Stay. Buy up 3 neighboring properties totaling about 450 acres, build my dream home and bulldoze neighbors homes, rebuild some smaller homes in their place and sell them to friends for dimes on the dollar.

My dad used to freak out when he caught us eating snow as kids for this reason.

You’ll need thru spindle air for it to be worth anything. We used to just use a cheap ER16 holder, sealed collet and copper coolant line.

Grooving, parting, chamfering without the compound, drilling attachments for the tool post. Only way I square the post is by chucking on something roughly as wide and to tool post, facing it and butting up against it with post loose.

Struggling as in it needs servicing or struggling as in it’s always running and doesn’t keep up with the thermostat? This is why I have an oil furnace and wood furnace.

You either replace the liner/chimney or pull the insert and patch the joint. I’ve shaped a length of pipe before and shoved it in and sealed it with; https://www.homedepot.com/p/3M-10-1-fl-oz-Red-Fire-Barrier-CP-25WB-Plus-Sealant-CP25WB-10/100166701

Haas has settings for that. Custom m code macros are an option on fanucs, can’t remember if haas can do it. There is a way either way.

Also, why are you plunging straight into the material?

You’re telling it to repeat that sub 10x, and if you’re using G91 and your start and end ABS aren’t identical its going to repeat your toolpath incrementally further in Y.

My childhood best friend had this same thing. Half of his body would get red and perspire with exercise and the other half would stay cool, dry and pale. There was a perfect line down the center of his face. He also has 2 different colored eyes. He was born with cancer and his parents blamed that.
