I made a hydraulic tool to measure high forces in the CNC machine. Hydraulics are great for high forces and I'll show you a few cheat codes to make hydraulics seal without high precision. You can buy drawbar dynomometers for roughly $1000 but you can also make one for "free" in an afternoon out of scrap parts. Thank you for your beer fund support! I appreciate your help to make these VJOs. Early access and better signal to noise http://www.Patreon.com/AvE

    LOL! WTF! Why am I giggling like a retard every time AvE references his “confuser”! I can’t help it!

    Is that a name brand PenisShield? You must make bank on YT

    I could sense the puckering coming from AVE as he burned through drill after drill. I'm probably going to hell for getting a kick out of his misery 😂 I already knew what was going to happen and yet couldn't stop watching.

    Teflon back up rings on the Quad rings might help. . Maybe install a zerk to pre load the guage and help with the air mitigation. Definitely a circlip or a retaining gland of some sort.

    Nice notable in the back…….. well played sir. Never a surprise!

    Is this why my machinist buddies are always trying to borrow my drills?

    why did i think you had a mill at home?

    Destroyed 1000 drills then tells boss its only the tip.

    I love how he's using the mill to build a tool to fix the mill

    what is that peni shield for

    In order to measure the proper draw bar force the gauge where the retention stud mounts in relation to the taper has to be the same as the tool holders. The draw bar in the Haas mill is made with stacked belleville spring washers. So any difference in length can make a difference in force. I have hired a person in the past to regrind a cat 50 spindle bore in the machine. One of the tests he did witch he said was very important was to measure the retention force on the draw bar. He said that regrinding the tapered bore lets the tools taper go farther into the spindle. In this can reduce the retention force on the draw bar. So your measuring gauge should if possible be the same length as a normal tool holder to the bottom angle of the retention stud. Where the balls make contact (In Haas's case). Some machine use special shaped fingers instead of balls. Errrrrrr I didn't mean that the way it sounds.
