    Thanks for the pointers all. Got them done. I'm not sure what the deal was with the first two, maybe just completely smoked endmill? Ended up doing them at 4000RPM, and 12ipm slotting, and 24 else where. So like 260sfm, 0.00075, and 0.0015ipt respectively. I used coolant since I don't have air blast, and it's not really an option right now. Spent a few min carefully aiming my coolant nozzles right at the cut area.

    Also got my drilling burrs conquered. Tried drilling with a 9/32 then a 5/16, and it helped but still had a burr. So then I found a well loved prybar that needed a tune-up, ground a sharp edge on it, and cut them off.

    Now for a little band-saw action, welding, and they will be done!

    Pry bars? Thot those were for separating the men from the boys?

    Files. Come in all sizes. And shapes. Not necessarily even wore-out ones. Power hacksaw blades are handy. Bustid taps often have good metal in 'em. Sandvik's "Bahco" blades are stocked many places and Sandvik know their s**t. Scrapped Carbide inserts can "ride again".

    Plenty of better "edged weapon" sources that cry bars.

    Threaded rod or slender Black Iron pipe makes a handle. Thread couplings make it longer-yet. PVC sleeves it "strategically".

    In short-order you'll have a "set" as can last for an age of use.

    ...with the reach to strip burr down the pesky inside of several size-and shape tribes of longish tube stock.

    "Hook" type pull is kinda neat. Even at neg-rake. Clever-devil can put both edges onto the same cutting "insert", angled.

    Time. Sumthin' as ignorant as handier, faster, more predictable post-op de-burr tools can save TIME. Money as well.

    Fab shop?

    Ever hear about shoemaker's kids going barefoot?

    Why mess with sharpened pry bars?

    Just "Go Fab yourself... a 'longer reach' "!!!

    Get GOOD at it?

    Medical School beckons...!!!

    Doubt it!

    But even so? Once you "own" any bit of knowledge?

    Nobody can ever take it away from you!

    Even if you give it away a hundred times, you still "own" the seed-corn as grew it.

    That's why I've always put a higher value on knowledge than money.

    Folks are forever takin' MONEY away from others.

    WTH? The ephemeral stuff seems to be forever just sneakily "evaporating" on its own if yah turn yer head for half a second? Go figure that one out?

    Folks as just took some of THEIR time to help solve YOUR problem also improved each other's store of wisdom .. and that of hundreds of OTHERS..as a byproduct.

    Ever' body brings what they can spare. Community of volunteers help process it.

    Nobody goes away hungry.

    Yah sure... young "genius" here onct figured I'd clamp the rule right to the work so I didn't forget to make that last confirmation and screw it up...

    Sure 'nuf "got it in one"!

    Took exactly wot I needed off the end of the stock, OFF!

    Good system. Worked a treat.. 'coz it took EXACTLY the same amount....
    off the end of the rule as it had taken off the end of the stock!

    Go figure I must ha' MISSED sumthin' along the way?

    Ve gang too soon Elt, und too late schmart?

    Din't throw NUTHIN' "away" either!

    Still have a bit of fun with handing over a rule - straight-faced - that don't start at zero no more!

    I mean? What's to bitch about? Meant to get your money's worth out of tools off the mileage of USE.

    And the REST of the markings don't have hardly any wear on 'em atall!

    Already measured! That's what the little slot is for. Take the worst of the tube away for saw cutting, and pre-mark it so I don't have to. Just need to make sure I cut the right side of it square.
