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!

    New to me colchester lathe

    “I should be able to start on electrical - my thoughts on that atm are maybe a new contactor needed - the thermal overloads will see twice the current at half the voltage...” I’ve had good success repairing the contactors on my old machines (late ‘50s to early’70s). I think of them like those...

    New to me colchester lathe

    I think you are on the right path. Of course, a machine tool all rusted up is not a good thing, but it isn’t a complete wreck either. My 11” Standard Modern looked similar to that Colchester (except a few parts missing) - there is some staining still present on the sliding surfaces, but like...

    Weiss VM32 CNC mill conversion

    +1 on Perry’s comment. You should be able to feed G code directly. In fact that is all I do in my CNC machines (lathe and mill). They are both pretty old machines, I have not found post processors for variants Acramatic A2100 or DX-32, but programming via text files (at the terminal or on a...

    Chamfering tool bits

    That is entirely your call. For general purpose work, looks good - go with the 45 chamfer (90 degree included angle on the tool). I have a few jobs that call for other angles, not a big deal, it is just a different tool (same process of calling the perimeter path). Generally there would be a...

    Moving lathe pull it completely apart?

    Just bolt it back together (you have already cleaned it well - that is the important part). The alignment was established when the machine was manufactured. Check by doing test cuts (~1” diameter bar, extended 6” from chuck, no tailstock support, cut ring about 1/2 wide at the outer end and...

    Boring small holes in drop forged wrenches.

    Start out with a little pop using a carbide center drill (~0.075”), then most any carbide drill (perhaps even the HSS drill).

    Tool How to drive taps

    I wouldn’t recommend running taps in with an impact wrench. I’m going to suggest that there isn’t one magical trick. You are probably already doing all the standard stuff, so I apologize in advance for reviewing the obvious). If you are doing that many large threaded holes, make up some...

    ER40 collet chuck sizes.

    True, machining can be very humbling, but also uplifting when the “impossible” has been accomplished.

    Please help me to choose a lathe for my project

    To machine an 8” diameter part, you likely need a machine (lathe) that will swing at least 10” diameter (250mm). One challenge is how you will hold the part (if gripping on the OD, then you have to have room for whatever you are using to hold the part). Holding thin plastic rings (in fact any...

    Best type of face mill?

    You’d want to think about the diameter. Obviously you can run a single cutter (called a fly cutter). More cutters allows you a higher feed rate for the same chip load per tooth, which takes more power - particularly if the tool is a larger diameter. It is kind of a balance / trade off. Fly...
