  • 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!

    Friction belt drive design

    So I added a belt guide. The bolt in the lower part of the picture. This actually works - still not perfect - slowly builds heat when idle - so the belt rubs a little when motor is running. The pulley when dropped just few inches engages the hammer and the action is controllable - i.e. I can...

    Product Cordless tools

    I have Bosch, Ryobi, Dewalt (recent) and most Chinese "brand" batteries for household tools. I wish there was standardization here - all 18 - 21v batteries are identical - they just have different molded plastic. Chinese strange brands usually follow plastic molding of a major tool brand.

    Machine Video of a healthy (?) Kopp variator

    Well, your RPC is indeed super noisy. My variator is similar but more noisy by far a lot more high pitch noise. But the main issue is that at high speeds over 1500 rpm it may suddenly loose power if speed dail is moved too fast. Something goes BOOM and power is lost. It is super noisy above...

    WTB 220v 1 phase 1 hp motor

    I have one like this for sure but sadly I am in Calgary. I am sure you find one in GTA - or get one from PA or Amazon or Motors direct. Did you check the capacitor(s)?

    US Tariffs

    This opens us up to potentially huge charges if package enters the US - it is now 145% for China but Trump wants it 245% and who knows it may go to 1000%. So you order a DRO from China for $300 and then suddenly you get a bill for $3300+++ I am not sure what would one do in such case - refuse...

    Friction belt drive design

    OK, I try adding a belt guide - which I think is just a metal rod that will guide the belt closer to the pulley. Once I try it I let you guys know how it went.

    Friction belt drive design

    So I have this somewhat semi complex friction drive as seen: Here is the problem. The motor turning left is dragging the belts creating friction - it is hot within 30 seconds. The idler needs to move a lot to make the belts catch. Its as if the belts have super narrow sweet spot where they...

    Sharpening large drill bits?

    How big do you go? Speed is determined by the diameter of the wheel for optimal SFM. So 3600 rpm is great for 6" and 1800 rpm is a bit slow for 10" - 1800 rpm is SLOW for 8" For drill bit sharpening you need soft wheel - i.e. it needs to fall apart easily to expose sharp pieces. I frequently...

    Self-Clearing Customs

    Both are close by in Calgary. I just not use UPS - FedEx has low rate for customs last time I used them.

    WTH - Got these inserts on Ali

    That seems like a pretty high price. I am 99% sure at such a high price these are regular run stuff. You seriously do not think that it costs the manufacturer to make top of the line insert of this size more than a 1 cad each - do you? The rest of the price we see is markup. Its all over the...
