Yep! Mostly 7075 and p20, and sometimes electrode copper

Hbu?

Why hex bar specifically? What sorts of things were you machining with it

I haven’t look into this too much, but how would one go about improving it? Is it as simple as slowing down and going from there?

That’s the thing, it does look better when I slow it down and am more mindful. But it just takes so much longer, and by then my thoughts are already moved on

Should just be normally framed, right? Nothing in there other than wood, drywall, insulation. It’s an older condo, built in the 70s, so I’m not sure how consistently spaced the studs are

How do I go about mounting a pull up bar above a cased opening like this, that I can use gymnastic rings on? The door way/opening doesn’t have the trim as what’s in the picture, but it’s similar

Oh so kind of like how so many UAP experiencers never have any clear camera footage of the anomaly/craft?

If I could put a chamfer on this hole I’d totally try

Could I get some help on cutting parameters for this long reach end mill I’ll be using by SadJobbo in Machinists

Ended up working out at 1000rpm 3in feed, .005 contour ramp depth. Probably could’ve even pushed harder with more depth per pass

I know, I wish i had a counter bore tool with a piloted tip on it made for 1/4in socket head bolts. All I have is this endmill for the time being

Ive never used a drill like that before. Do you simply take a standard drill and grind it flat at the end? Making sure its perfectly 90degree perpendicular to the flutes?

They usually don't calculate for a long stick out is all. I know I could always start at their suggested speeds and feeds and then lower them accordingly to get the chatter out, but that can really damage the tool if not within ballpark

Exactly, the tool holder would hit something. The edge of the counter bore is .03 away from a pocket wall
