Scammers have burned people on this forum. Urgency, secrecy, excuses, selling for friend, newish members, FUD, are RED FLAGS. A video conference call is not adequate assurance.

  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

    Timing belt and critique drive concept please

    The idea that Linux has fewer bugs than Windows is a myth. There is far more security research done to try to find bugs and security issues on Windows than on any other platform including Linux. And far more effort put into fixing them. Having said that, Windows is not a very appropriate...

    Harrison M300 Taper Attachment

    It should be mentioned that there is a much bigger difference than just the cross sectional area. a basic bar in compression looks like this. With a perfectly straight bar made of some hypothetical ideal material, the width is irrelevant and it can carry infinite load. With a real material...

    Harrison M300 Taper Attachment

    You have written a book and only showed some bad photos. I suppose I'm guilty of worse;) we are making tapers. It is hard to move the headstock, so we must be moving the tail by some amount. How much? well that's what this tool will help us with. And specifically without changing the...

    Harrison M300 Taper Attachment

    In tension or compression, a rod is either supported at one end or both - or somewhere else. The one end supported loads are generally 4 times the both end supported ones - for moment reactions from transverse load. But the other than more deflection under the cutter, I fail to see the...

    Harrison M300 Taper Attachment

    it is unclear to me what this part looks like, but it seems obvious that the key point is slenderness ratio

    High speed CNC router spindle question

    I'm not sure exactly what your setup looks like, but since you mention VFD and overheating i can make a very general suggestion. More heat caused by higher current through the windings at lower frequency (and slower speed)

    Vintage Drill Press Designed For Real Humans

    That lever is a very bad choice. As it is depressed, the angle of the spindle will change. No good for drilling straight holes. A knuckle in the spindle or a slot in the lever can fix this, but there has to be enough rigidity to force the pin into the correct location

    Dabblings

    This seems like the best solution to me too. This will also reinforce the frame a bit. You don't even need to weld if you use some through bolts. The biggest thing to pay attention to is making sure the gaps between the boards are as small as possible

    MT2 tailstock 3/4" weldon shank?

    This is what I would suggest too. Chuck the strait end in the head stock and use a dial to make sure it is good. Then loosen all of the screws in the tail stock and mate the taper with light pressure. rotate and re-check with the dial and then fully mate. Then tighten the screws in the tail...
