    Yet another 72 x 2 grinder

    This time around instead of showing everyone boring video of drilling 50 holes I just talk for 10 min about what is missing from other videos on the topic. Such as angle I used on the tracking and how tracking works etc. How much time it takes, how much it costs. Stuff like that. Seems no one...

    Temu Coupons... be very careful

    Its a discount aliexpress site - more or less for things like throw away clothing. Quality even by Asian standards is low.

    Center drill or spot drill

    You can imitate spot drill with center drill by using only the tip. For carbide drills you should always use spot drill or similar imitation as the angles need to match or your carbide drill may shatter. For HSS it does not seem to matter as much - I think main issue may be accuracy - spot...

    Tool Lathe Stops

I also don't see huge advantage from having a VFD - some people run it fast for metal and slow for wood or something like that thus maybe it makes more sense - apparently some ceramic belts like super...

    Two 240 to 480 transformers

    I was thinking of taps on the 480v transformer - there may be some to adjust the voltage up. I made my own taps on a 600v transformer to go down in voltage. I actually run my motors at +10% voltage as both transformers I have are 480v and 600v while motors are rated at 440v and 550v. No issues...

    Two 240 to 480 transformers

    Sorry, no. But maybe you could try to run the 480v a bit hotter - don't know. I would not have issues running 550v motor on 480v or 500v.
