  • 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.

    Indexing rotary table for milling machine 42" Dia Ser No.15066, $3500, North York, ON

    When I lived in Toronto a place called Active Surplus on Queen St. had giant hard drives in crates.....I always though they would have made a great coffee table. This would even be better. Imagine stubbing you toe on this coffee table at 3 in the morning?

    Travelling from Squamish to Calgary?

    Thank you for the space to post. Just an update. I stumbled on VanKam Freightways LTD. . Looks like they only do western Canada. Very helpful. Reasonable pricing. I am going to give them a try. Will update after I receive my items. Might be a good option for the guys out west if...

    Travelling from Squamish to Calgary?

    Thought I would post here...you just never know. I'm trying to get 5 discontinued fence panels from Rona Squamish to Calgary. (Or somewhere closer to Calgary). They measure 95-1/2" W x 12" H x 1" thick. Not too sure of the weight, but guessing each panel would be 30 - 40 pounds. Willing...

    Helical cut gears - design solutions for lateral forces.

    Also, can anyone explain the purpose of having bearing sheilds/seals inside and oil filled gearbox? I would think these would not be needed.

    Helical cut gears - design solutions for lateral forces.

    @Mcgyver, I did read up on the Bellville washers. Looks like a great idea, but I can not find any in a 6004 or 6005 bearing size that would fit into the 0.014" I have available. In my reading about them I did read that it is preferable to load up the outer race of the bearing. No...

    Helical cut gears - design solutions for lateral forces.

    Basically I would be doing the same thing, shimming the shaft to one side, but the shim would have a bit of "flex" for lack of a better word? I'm not sure if I could get one thin enough? Presently I have ~0.015" play. Even if I could one thin enough, do you think it would last? I have...

    Helical cut gears - design solutions for lateral forces.

    Ok, that makes sense. I am unable to measure the play on the center gear. Maybe with some clay and preloading either the input or output gear to get the center gear to shift to its extreme I could get a rough estimate. My idea is to shim the input shaft to the left. Shim the output shaft...

    Helical cut gears - design solutions for lateral forces.

    It is power on/off ......but it does reverse the gear box loads.....not the direction of rotation.......when the power is on the motor feeds the gearbox and drives the back wheel. When the power is off the back wheel drives the gear box (Reverses the loads on the helical cut gears. Gears are...

    Helical cut gears - design solutions for lateral forces.

    Herringbone cut gears or dual helical cut gears should cancel out the lateral forces. The gears are about 10mm thick. Might be a challenge to cut something like that. Straight cut gears would also remove the lateral forces, but then I'm trading one noise for gear noise.
