- Gday, this is the finally video on the modification to the column of the mill, I did do this all off camera simply because I didnt want to bore you guys with similar content, I really hope you dont mind but please let me know in the comments if it has, in the end the modification worked and repeats within .002", this is plenty good enough for the work I do, please enjoy the video and thanks for watching, Cheers
Nice work Matty... I like what you said "It's the best I can do right now" there speaks a man who's constantly improving... See you on the next one...
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
At the moment it's 200 to 1 thumbs up. This project and its presentation deserve that rating. I thank you for demonstrating how best to deal with the biggest problem of round column mills.
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
I think that's the best fix I've seen so far! I'm going to try and make one. Thanks
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
Nice one, it looks silky smooth too
Gday Tom, it really does slide easy, a lot easier then I thought it would, thanks for watching, Cheers
Great job Matty. I don’t think it moved at all when you raised and lowered it. I’m going to have to redo mine now. I like that you can adjust the pressure on the bushing also. That’s the best improvement I’ve seen so far for the round column problem.
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
Good job! Thanks for sharing.
Good solution Matty it works really well and looks like it's a bought in accessory. Great work. Tony
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!
Nice clean modification, well done.
Thanks very much, appreciate you watching and commenting, cheers
Nice explanation, presentation and nice design approach. Your solution has something others don't; compactness. Others take scads of space, making them intrusive, huge in dimension, and then, considering the size of the contraption, not very rigid. Your approach if it was beefed up a bit more would still be very reasonable yet there would be significant rigidity.
Keep up the good work my friend always love watching you work
Gday Paul, I’ll keep trying mate, appreciate you watching and commenting, cheers
Well it looks like you gotter licked! 😊 I wouldn't sweat doing stuff off camera, sometimes the camera just takes the fun out of it (although I wouldn't have minded seeing some shaper vs. delerin 😉). The attachment looks very sleek, like it was like that from factory. Great job, Matty! Cheers! 👍😁👍
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
Hi Matty, thanks for the design. I was thinking getting a mill/drill with round column but issue was the head movement when milling. This design surely overcomes that. The workspace is far more than a normal knee mill.
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
I didn't think the paint was tacky, it's a great blue :) As for .002, that's nothing to sneeze at. Forget to clamp the knee on a Bridgeport and you're out that much. Nice fix!
Gday Everett, I pretty happy with the results, I dont think I can get it any better, thanks for watching mate, cheers
Nice work Matty, 1.5 thou is not bad at all. I was thinking about your plastic bushing, and the two adjustment holes - you could add tapped holes above and below for one of them, on the back one maybe. This would replace the single central hole, meaning you have good three point contact on the straight piece, it should hold on to it better with less play. Think of using a thumb and two fingers to hold something instead of a thumb and one finger.
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
metal work is always very impressive. I live in a world of 2 by 4 s. A square cut is a fee handed cut with a circular saw, experience makes it perfect 9 times out of 10 and that one off cut....well, tradition says you blame your friend for that and then tell him not to worry because we needed fire wood anyway. Amazing what you all metal workers can produce.
Gday, nothing wrong with wood working, I just don’t like the mess it makes, appreciate you watching and commenting, Cheers
G'day Matty, I'll catch up in me next coffee break my mate
Thanks for sharing and best wishes to you and yours
Gday Ralfy, I hope you enjoy the video, take care mate, cheers
I knew you would figure a better plan .. great job ! ENJOYED
Gday, I got there in the end mate, took a bit though, thanks for watching, Cheers
Very nice work Matty. Have a great weekend, Gary
Thanks very much Gary, enjoy you weekend to mate, Cheers
Hi Mattie,
Really great result mate 👍
Regards
Robert
Thanks very much Robert, second time is always better then the first, thanks for watching, Cheers
Gday Matty, that looks good mate, i wish i bought the round column sometimes, i like that you can move the head around for them awkward drilling jobs.
Gday, they do have there advantages but I think I’d buy a dovetail column next, thanks for watching, Cheers
G'day Matty. That was an excellent solution to a difficult problem mate. Much better than the rod idea. Just like the Aussie movie "The Castle", you're a real ideas man Matty. Cheers, Aaron.
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
Hi Matty... nice looking, & it still goes up & down. My suggestion is to tighten the side screws more to get a really snug fit on the vertical bar, lengthen the bar another 50 to seventy mm for a bit more stability. ++ when the column lock bolt are tightened everything will be spot on
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
Not perfect? Everything you do is perfect! You're not a factory for God's sake. I saw those oil cans you made for Christmas presents! I finally got a piece of aluminum pipe to try and copy your design. I was impressed!
Gday, you’ll enjoy the oil can build, takes a little thinking but you’ll enjoy it, Cheers
G'day Matty! 2 thou movement is a great result comparing to what it was before. You did well mate. That 2 thou is easily remedied if need be after the adjustment is made with an indicator. Great job. 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
Quite a bit better now, good job.
Wonder if a shot of non-stick spray from the Mrs' kitchen on the guide rod and block would allow you to tighten up the side adjust screws a tad and reduce play further? Thx for the video.
Gday, that’s a good idea to try some spray, bit of spray grease would work ok, thanks for watching, Cheers
Nice work mate !
Having a dovetail column is no guarantee of accuracy either , my HM46 had a tilt in the Y axis and this was caused from crap under the column mating surface with the base - fortunately it was all sorted with a clean and rub with a file .
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
Very nice build!!
Thanks Chuck, appreciate you watching, Cheers
GDay from GA USA, I am going to use your idea for my round post also, thanks
Gday, go far it mate, Cheers
Nice job Matty 👍👍👍 Going to save you a lot of time in the future. Cheers, Alan.
certainly will mate, nothing worse then having to clock everything back in again
very good proyect
LOOKS GOOD TO ME MATE. REGARDS RICHARD.
Thanks Richard, appreciate you watching, Cheers
One comment I'd make Matty is I would turn the rectangular bar 90 degrees to give the greatest rigidity against rotational flexing, and personally I'd dump the plastic bush and tig braze three bits of brass rectangular stock, then machine it to the same as you made the plastic block and use the three point adjustment suggestion. ( easy enough if you don't make the brass too thick)
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
Good job Matty what make is your round column mill. And I herd you say if you could do it again you would get the square column one . If you don't mind and have the time could you tell me the name brand motor size . I have a small shop just as you and I'm in the market for my first mill. I don't have the room for a full size mill just looking for a bench top one like yours and trying to buy smart and learn from others before purchasing. Thanks for any help you can give.
Gday Anthony, can you please send me your email address to ttmrj@telstra.com Cheers
Hi Matty. I not sure if you will be contracting to Airospace to make parts for them. If it's 1.5 th out that's more then enough for hobby work. Plus you gain all that head height you park the bloody tractor under it. Nice job and looks the part.
Gday, I’m pretty happy with the tolerance it holds now I’ve used it for a good while, thanks for watching, cheers
Good job👍
Thanks Matty.
Cheers Don,
G’day Matty. Well done mate, trying to restrain a round column would be very difficult. Square bar is definitely a better choice. Keep up the good work.
Cheers
Peter
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
Is this vertical blue bar on the other side of the column as well?
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
Hi Matty, have been watching you for a while but I’m in the process of buying one of these mills and your solution is by far the best, just wonder why you never used a round bar, would there have been more flex in it !!
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
Great work! Much improved.
Thanks very much Bryon, cheers
Nice one Matty, cut my first single point thread this week, I have some M24 x 100mm bolts and nuts if they are any use
Gday Terry, great job, cutting threads is really enjoyable I find, I think I right for large bolts now mate, cheers
Elinize emeğinize sağlık güzel olmuş
Thanks very much, I translated your comment to English, appreciate you watching and commenting, Cheers
I rather like it its clean...simple..
Thanks very much, cheers
Great work Matty looks like a really good mod and with minimal runout when moving up and down. I have just bought my first mill and it is also a round column mill so I’ll be looking at doing a similar mod to this in future.
All the best.
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.
Good Job mate, Will make the Z axis for a DRO install? nice and easy,
Gday Gary, certainly a lot easier to fit a dro now, appreciate you watching mate, Cheers
My only thought is if the bar attached to the head isn't perfectly vertical then the head will rotate as it moves up and down. Put an indicator on your new base clamp with the indicator as high as you can get it on the bar then run the head up and down.
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
nice one matty
Thanks very much Max, appreciate you watching, Cheers
Looks great Matty and plenty accurate for a round column. Can you adjust that few thou with the set screws you put on the delrin piece in the odd time you want it relocated spot on?
Enjoyed the video, stay safe and cheers mate!
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
It goes back to Zero when you tighten it back down, or it must be within .001 it looks like. It would be hard to beat that Matty I think no matter what you do on these Round Column Mills. I was wondering if there was a way to get some of the weight off of the Head on these, if that would also help. Maybe some kind of Air Shock support?
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
Hi Matty, what make and model is your mill?
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
How long until you have some for sale? Let me kmow how much and I'll buy one.
Is there any reason that you can't attach straight to the 115mm shaft with a block instead of making the ring bracket?
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.
thats much heaps better Matty and your right you should of videoed that block lol cheers fella love the vids
Gday Paul, yes I should have filmed it, maybe next time, thanks for watching mate, Cheers
Thanks MattyCheers
Thanks for watching mate, Cheers
great soultion.
Thanks very much, cheers
That's a nice mod. Good idea.
Thanks Rustinox, appreciate you watching, Cheers
Matty that video is you to a "T" have a shot give it my best and whats next......you will go back and play "I KNOW IT", well done.
Gday, couldn’t leave it alone, just had to have one more go, thanks for watching mate, Cheers
That seems to have fixed it 8-)
I think so mate, Cheers
Matt do you make things for uthers
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
Good problem solving there buddy. I sent you an email.
Gday Tom, I got your email and I’ll get onto it mate, Cheers
The best modification for a round column mill is to sell it to someone who only wants a drill and then buy a proper mill for the same price.
Gday Ian, yep I agree and hopefully this will be on the market soon all going well, thanks for watching, cheers
2 Thou, Tut Tut Tut, come on Matty get a grip, You can do better than that :) Good job mate, Much better than the last load of crap you tried lol. Keep up the Great Videos.
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
The camera is too close to the mill, my eyes are hurting, have to stop watching.
Good safety glasses are a great investment! 🤓
