  • 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!

    Motion when locking the axis

    While I'm do not have years of experience scraping, I did successfully scrape in a couple of angle plates and straight edges flat and square. The plan was to blue the dovetail and check for contact along the already scraped gib, this would help me confirm that the gib taper angle/general fitting...

    Motion when locking the axis

    Thank you, that makes me feel a lot better about taking apart the table and saddle to try and properly inspect the gib contacts :) (also want to try my new scraper!) There was crusty corrosion on the inside of the spindle taper which I cleared with a brass brush. After cleaning, I measured...

    Motion when locking the axis

    But if they are tapered along their width wouldn’t they act like a wedge and get stuck the more your try and push them in? Curious how this mechanism works

    Motion when locking the axis

    Yes it was the first thing I sent and the reply was “That motion is normal. If that is causing an issue with the motion of that end of the gib, once you get the gib where you want it, just leave that screw alone and take up the slack using the other gib screw.” Then when I was arguing that two...

    Motion when locking the axis

    Yes brand new, I've been in touch with technical support who initially said this play is normal but then when I called they immediately offered to send a new gib blank. I have couple of other issues on this mill including a rusted spindle which they already send a replacement for and it's...

    Motion when locking the axis

    that's what I figured, I'm hoping there is enough "meat" in the gib that I can blue and scrap it for a better fit until I get the new full length gib blank to refit. I know this won't change the top and bottom clearances but at least if it's properly fit it shouldn't move as far as I understand...

    Motion when locking the axis

    Precision Mathews are sending me a new gib blank to try and refit. Until it gets here(there are apparently huge backlogs at CBSA and my other package from PM has been stuck for 3 weeks!!), I plan to blue the Y dovetail to see how much of problem there is with the gib that keeps moving every...

    Motion when locking the axis

    Thank you this is very useful information. When measure the side ways movement, what’s the common place to take the measurements? Locking X and measuring movement in Y at the center of the table will result in much smaller number than on edges of the table for example

    Motion when locking the axis

    I just received a PM-728 and working on setting it up. I’m fairly new to adjusting tapered gibs setup and I noticed that my X and Y axis move in the range of .0008-.0016” when I lock the axis. I’m assuming this is not normal and my gibs are too loose? Also my Y axis gib moves up and down...

    Product KBC Grade A surface plate dyed granite??

    I did some measurements today using a 2um indicator and a gauge block(a sort of diy repeat-o-meter) and local flatness seems to be within the tolerance in the certificate which was .00015”, did you measure yours? I can’t find any definitive information online but dyed granite seems to be the...
