  • 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!

    Product Favourite Tap & Drill chart

    A few years ago I posted my own chart of drill sizes, in increasing size order for the 4 types of drill systems commonly available - numbered, lettered, fractional and metric. I find I use the chart a lot. Sorry, but my focus was not on identifying tap drill sizes - for that I have a chart from...

    Sorry about that. Each indicator mark on my dial is 2 thousandths of an inch, and I now move the dial 6 or these before it starts to move. I guess that's .012", not .0012 like I typed. My bad...

    I used a washer because it was suggested that I try that. I just came in from the workshop having added a washer like you can see in the attached photo. This did not eliminate the backlash - probably no way to eliminate that entirely with this design. But, it further reduced the backlash to...

    OK - no locktite - of any colour. Or, any spelling! John's description is spot on, and I will try a washer to try and minimize the remaining tiny gap that still requires me to rotate the handle maybe 15 degrees before the table starts to move. Thanks everyone for all the great ideas...

    Peter That is correct. I shifted the [art 521 away from me as I face the machine, and that was done with a hammer and small piece of wood. It seems I did not have to use this approach - I could have just tightened the but instead - same effect... The 520 part is exactly like you describe. I...

    A really big OOPS... Susquatch and Craig have been confused because I apparently said the wrong thing - or the right thing backwards... Anyhow - sorry for my lack of precision. I did not hammer on the leadscrew in making my repair. I actually hammered on what Susquatch is calling the collar...

    I like your approach to this. But let me say this... I certainly agree that tightening the nut would have solved the problem. It is just that I had the parts disassembled when I took the hammer and wood to see if I could move the leadscrew backwards - away from me if you like. And that worked -...

    Thanks for the further input. I am nowhere an expert on machinery and the field of engineering is far from my mind. But - that nut that holds the handle on would seem to me a simple, yet adequate way to keep things from getting further apart. It was you who suggested that tightening the nut...

    Well - that was an enlightening experience. Bottom line - I got the .300" problem greatly reduced. I still have a bit of backlash - about what I was used to before this problem started happening. With some fear and trembling I started removing parts to get at the mechanism, and that went well...

    Thanks very much for this additional input. Also very clear - apart from me not knowing exactly what all the terms mean. See my expended reply below... Cheers, Brian

    Thanks John. I will try and fix things today. If that does not work, I'll get back to you. Cheers...

    Thanks for the suggestion. Those parts you mention are for the X axis shaft, but I see their equivalents on the Y axis drawing - parts 521 and 525 I think. That drawing leads me to think that the shaft is unsecured on its back end. If that is true, then that adjustment must be in the front and...

    Wow! What a clear and unambiguous description of my problem! I followed this with complete understanding - apart from knowing what the heck a screw anchor looks like. Its function is now clear enough - the screw itself should NOT move lengthwise - it needs to be held in place so it just rotates...

    Peter - I cannot recall whether the Y axis always was worse then the X axis. I think both started out the same, but only the Y axis turned out seriously out of normal range for backlash. It did become progressively worse... I do not recall there was any particular moment when the gap all of a...

    Peter - I have looked at my milling machine carefully and here's what I found... I can see the X axis screw quite clearly from both ends. I can also see the nut it passes through. This lead screw looks very lubricated. It is decently wet and there is a huge gob of grease on both sides of the...
