• Scam Alert. Members are reminded to NOT send money to buy anything. Don't buy things remote and have it shipped - go get it yourself, pay in person, and take your equipment with you. 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 Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click 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!

    HAAS CNC file.

    Can't go wrong with Fusion 360 - I've been teaching/reselling Mastercam for the past 30 years but for a hobby shop it's just too expensive. Fusion 360 is free (or very low cost) and provides tons of free post-processors and also has parametric design features. Just my 2%

    HAAS CNC file.

    Seems like a very basic G-Code file to me with an Excel spreadsheet for operation information.

    measure over pin method for gears

    Just checked - they are 14-1/2 PA :(

    measure over pin method for gears

    @Susquatch I might have a complete set of the cutters you need - just let me know!

    measure over pin method for gears

    OD = (N + 2) / P = (30 + 2) / 20 = 1.600"

    measure over pin method for gears

    If OD = (N + 2) / P then in your case you would have a P = (N + 2)/OD = (30 + 2) / 1.606 = 19.925 Looks pretty close to a Diametral Pitch of P=20

    measure over pin method for gears

    Metric gears only have 20 degree pressure angles - all others are from imperial gears (14-1/2).

    measure over pin method for gears

    OK, so here goes, using PeterT's example above: m=1.0 N=15T PA=20°: 1- Diametral Pitch (P) --> m = 25.4 / P P = 25.4/1.0 = 25.4 2- Pitch Diameter (D) --> D = N / P D = 15/25.4 = 0.59055" 3- Outside Diameter (OD) --> (N+2) / P OD = (15 + 2) /...

    Depends on MH version - in my PDF 26th edition it's here:

    measure over pin method for gears

    For what it's worth, look it up in the Machinery's Handbook - very well explained. If needed, I can go thru an example of the calculations and even the tolerances of mesurement:
