Round column mill modification 

Gday Tom, it really does slide easy, a lot easier then I thought it would, thanks for watching, Cheers

Gday Paul, it’s certainly a big improvement on the first attempt and one day I might come up with a better solution, thanks for watching mate, Cheers

Gday Mark, thank you for the kind words, the thumbs down never worry me really, it’s very hard to please everyone when you make videos, kind comments are what makes me want to keep filming, Cheers

@@MattysWorkshop You may already know you have viewers from the opposite side of the planet, Wyoming in the US

@@markkoons7488 im amazed with how many subscribers I have and its great yo know that people enjoy what I do, it really is a lot of fun mate

Gday Lloyd, go for it mate, thanks for watching, Cheers

@@MattysWorkshop I agree. Good job Matty. I wonder how it will go regarding wear ? I was a bit surprised when you went round column considering this is a well known issue. I was looking at this sized mill today and price wise there's not much between the two sorts. I would expect the square column to be a bit more rigid as well. Cheers Rob

@@Xynudu Gday Rob, certainly proved the round shaft version was shit but the square version worked, I think you would really enjoy having a mill and if I was to buy another it would be a square column, appreciate you watching mate, Cheers

Thanks Richard, appreciate you watching, Cheers

Gday Tony, I’m really quite happy with the results and I don’t think it looks out of place to much, appreciate you watching mate, Cheers

@@MattysWorkshop all you have to do now Matty is to paint the rest of the mill the same lovely blue and it will be a factory fitting!

Gday Chris, the Delrin vs Shaper is a lot of fun, big cuts medium step over and silky smooth finish, feels like you have a monster size machine, I wish now I did film that part, thanks for watching mate, Cheers

Cheers Don,

Gday Everett, I pretty happy with the results, I dont think I can get it any better, thanks for watching mate, cheers

Thanks very much, cheers

Gday Steve, knowing what I know now I’d definitely buy a knee mill or a geared head mill before I’d buy a round column mill, there still not all that rigid but that’s only my opinion, I think a square column has a lot more advantages, Cheers

@@MattysWorkshop Thanks the thoughts then pehaps a knee mill is better here.

@@stewanish this is only my opinion and thoughts, I’d certainly be looking at a knee mill before anything else mate

Gday Paul, I’ll keep trying mate, appreciate you watching and commenting, cheers

Gday, I think that was a good idea putting in the adjustment bolts, if the block wears over time at least it can be adjusted easily, appreciate you watching mate, Cheers

Congratulations on 3500 subscribers :-)

Gday Craig, not a bad idea using the extra adjustment screws, might put that on the list to do soon, I’m blown away with the subscriber count, growing quickly now, thanks for watching mate, Cheers

Gday Aaron, the first attempt was a screwup but I think this will do everything I need to do in the future, appreciate you watching mate, Cheers

Thanks Chuck, appreciate you watching, Cheers

Thanks very much Max, appreciate you watching, Cheers

Gday, I got there in the end mate, took a bit though, thanks for watching, Cheers

Thanks very much, I translated your comment to English, appreciate you watching and commenting, Cheers

Gday, you’ll enjoy the oil can build, takes a little thinking but you’ll enjoy it, Cheers

Gday Ralfy, I hope you enjoy the video, take care mate, cheers

Thanks very much Gary, enjoy you weekend to mate, Cheers

Thanks very much, appreciate you watching and commenting, cheers

Gday, they do have there advantages but I think I’d buy a dovetail column next, thanks for watching, Cheers

Gday, nothing wrong with wood working, I just don’t like the mess it makes, appreciate you watching and commenting, Cheers

Thanks very much Robert, second time is always better then the first, thanks for watching, Cheers

certainly will mate, nothing worse then having to clock everything back in again

Gday Ted, I’m at the maximum length on the square bar, if it’s longer it will hit the base when it’s lowered, thanks for watching, Cheers

Thanks very much, cheers

Gday Yves, certainly a big improvement on the first try, it’ll be good enough for what I do mate, thanks for watching, Cheers

Thanks for watching mate, Cheers

Gday, I’m pretty happy with the tolerance it holds now I’ve used it for a good while, thanks for watching, cheers

Gday, go far it mate, Cheers

Gday Peter, I should have used square stock from the start, I really don’t believe you can get it 100% spot on but it’s close enough for what I do here, thanks for watching mate, Cheers

Gday, I’ve had this on for a good now and it’s been flawless, the plastic bush hasn’t worn at all, it’s been better than I expected, cheers

Gday, that’s a good idea to try some spray, bit of spray grease would work ok, thanks for watching, Cheers

Thanks very much Bryon, cheers

Gday Anthony, can you please send me your email address to ttmrj@telstra.com Cheers

Gday Ian, that the model I’ve been looking at n the back ground, might see what the future brings, thanks for watching mate. , cheers

Gday Terry, great job, cutting threads is really enjoyable I find, I think I right for large bolts now mate, cheers

Gday Gary, certainly a lot easier to fit a dro now, appreciate you watching mate, Cheers

Gday, couldn’t leave it alone, just had to have one more go, thanks for watching mate, Cheers

Gday Tom, I got your email and I’ll get onto it mate, Cheers

Gday Dave, the square bar is spot on vertical going by the digital level box, I thought the same thing but I can live with 2 thou error on most things I do, appreciate you watching mate, Cheers

Gday, I’m happy with the results and it’s really handy being able to adjust z height now, there’s quite a few modifications that can be done to a new mill, all good projects, thanks for watching, Cheers

@@MattysWorkshop There's a very simple reason why this has been an improvement and when I had a quick look around all the others doing this sort of mod also did as you first did. If you have a look right in your last short and consider how the beam is being loaded when you mill its actually being bent NOT twisted. If you throw in a milling cutter and start winding the X-axis then the head is trying to twist around the column against the load on the cutter. Which is fine because a round profile resists twisting. But the vertical beam you have added is not on the center line of the column its out on a radius. So the load it is getting is at right angles to the radius just like when you put a spanner on a nut. You don't twist the spanner you push on the end. So that vertical beam you have added is under a BENDING LOAD. Tubes and solid round are great for twisting (as in torsional loads) but suck at bending. Rectangular sections are great for bending loads and lousy for twisting. SO just by switching from a circular to a rectangular section you have made the mill stiffer. You'll find that if you do another mod and turn that bar 90deg about its center and put the wider side against the bending load it should make the mill even stiffer.

Gday Terry, the round bar had to much flex I found, if I was buying this mill again I would certainly buy the square column not the round, I have found the round column isn’t as rigid as it looks in my opinion, the belt drive is a good thing but having a gearbox would be a lot better to, hope this helps mate, Cheers

How about a piece of precision ground stock...suspension shop near me throws away old struts some they gut and grabbed a few one end threaded and fairly long am guessing from a 4×4 or suv

Gday Paul, yes I should have filmed it, maybe next time, thanks for watching mate, Cheers

Thanks Rustinox, appreciate you watching, Cheers

Gday Ian, yep I agree and hopefully this will be on the market soon all going well, thanks for watching, cheers

I think so mate, Cheers

Gday, I have to do a bit fiddling around with the adjustment screws on the delrin yet but for 99.9% of things I do it’ll be more then good enough, thanks for watching mate, Cheers

Gday George, yes mate I need to try a little harder, I think it’ll do everything I need to do mate, thanks for watching, Cheers

Gday, the vertical bar is only on the one side, I originally used a round bar that didn’t work out so I turned it 180° and used a square bar, Cheers

Gday, sadly I won’t be selling these, the straight shaft needs to be on the ring so the head of the mill can still be turned, hope this helps, cheers

@@MattysWorkshop That makes sense. Thanks for the response.

Gday, I never thought about gas struts on the head, I really like that idea a lot, maybe off to the drawing board, thanks for watching mate, cheers

Gday Matthew, all depends on what it is mate, Cheers

@@MattysWorkshop the part i need is a 5/16x24unf to 10mm threaded stud

@@matthewmeuleman9872 Gday mate, send me an email ttmrj@telstra.com Cheers

Gday, my mill as a Hafco MetalMaster HM-32B, i'm possibly going to sell it soon and upgrade to a Bridgeport style milling machine, Cheers

Good safety glasses are a great investment! 🤓
