    In my experience this is way off base. Split points came about as a good way to reduce the thrust requirement to drill holes. Same with 135° point - shorter cutting edge length = less thrust. Higher...

    Pressing will not generally work well to take out a warp, peening is much more fine tuneable. Like for instance if your bar has 3 corners touching flat and one up in the air. It is also much easier...

    I'm sorry, but pulling a piece of steel through a boring (or milling) cut with a cable on top of a bench is just silly. You need a positively located and precisely fed setup for something like this...

    Don't need to do any of that to get 50 millionths though, just adding lines on the dial would have done it. And I've already got a ½ μ indicator if I need that.

    Yes, that is nice. I've got a Compac that has about the widest graduations for a .0001" indicator I've ever seen. Don't know why they didn't add some extra lines in and get down to .00005" - would...

    I offered more than once to help out with zero response, apparently they feel they have it covered. Or maybe I'm just not worthy... :D

    And use the most openly dressed, free-cutting wheel possible until you have the part nice and flat. After that you can get your finish. I don't like to peen or use heat to straighten unless...

    Probably depends on the parts you're looking for. I have an 818 of the latest vintage and have seen some of the prices paid for parts by the company that last owned it. Bourne and Koch has some...

    Pardon, but I am going to be blunt now: Send it out if you do not have the travel. You are worried about the cost of buying a custom ball-nose endmill (fairly cheap) but are contemplating building a...

    I'd lean toward 4340 too. D-2 is better for things needing some resistance to abrasive type wear.

    Good luck Sami, you got this. Having had to deal with plenty of my own shitty health issues and the mental ones that come with, I know how that goes. Good that you've made it out to where you have at...

    Apparently this info is top secret. Either that or OP doesn't read very well. This has been asked at least 3 times, and OP has replied at least a couple afterwards without answering those questions....

    Boeshield T-9 is the equivalent to LPS-3. Both are excellent in humid conditions and for semi-long term.

    Gotta answer MrWhoopee's query. Is this a clearance cut? As in clearance so nothing hits this section of the part? If it is, I would just use any old ball mill and step it in with the readouts or...

    Howdy. Search first, ask second - if you can't find the info you're looking for. If it's been covered a million times you may not get any answers, or get cranky ones. If you have a lantern toolpost...

    Just may need to use a little softer wheel with that method I think. It will be a lot gentler on the wheel so it won't break down as easily. I like to run ⅓ wheel width stepover for finish grinding...

    The Black Diamond grinders have cams also. They are interchangeable for different clearances. They offer 7°,12°, or 16° clearance cams. Standard is 12°. They change pretty quick: remove a couple...

    Add me to the list as well. Most of the shops I've worked in only had spiral point taps. But those were mostly manual machines.

    This is how it should be done... Expecting a drill to do this level of work (as the O.P. seems to be) without performing the necessary operations is not the fault of the drill... Especially with a...

    Yes, I get that, but then each side forms a helix, so....anyway, no big deal. Cuts nice, that's all that matters.

    The ones called helical points that I'm familiar with are Bickford, Spiropoint,...
