Tramming a round column mill 

How did you get on? Did you get it square enough?

Thanks for your comments. It would be good if these mills had some kind of adjustment. I hope you are able to square up the head on your one.

Thank you for your comments.

Thanks for watching.

Hi, thanks for watching and thanks for the tip. I also have a vise that looks like swiss cheese from the previous owner. Maybe it will work on that...

Thank you and thanks for watching.

Thanks for watching and your experience on table repair. At this point the vise sits flat and clamps down well so I'm going to leave it.

I noticed a big difference once it was in tram. Mind you, mine was so far out that anything would have been better than what it was. Thanks for watching.

Hi Ben, thanks for your comments. Thanks again for posting your video on this process.

@@thehobbymachinistnz No worries.

I bought a Grizzly version of a similar model, here in the USA about 26 years ago. I’ve made numerous modifications. But fortunately, it was trammed very well. I’ve not had that go out of adjustment and when the head is raised and lowered, tram remains the same. As always, quality control matters. Different companies sell the same equipment at different prices and that results in well aligned machines or poorly aligned machines. Nice job. I wonder if the same guy who destroyed the table dis something so egregious that it knocked tram off. Ring Fu is a quality manufacturer whether so,d under their own name, Grizzly;s or some others. It’s hard for me to imagine it got out of the factory that badly aligned. Maybe dropped in shipping.

@@melgross Re tramming isn't difficult. I did it on my Naerok mill when I erected it in my shop.

Thanks Gr eg. Yes, I mostly use the vise and sometimes a rotary table.

Thanks for watching.

Hi, thanks for watching. That is a good question. I have raised and lowered the mill head several times since tramming it in, but I have not checked to see if it is still trammed in. That said, the cutting marks on the milled work show that both ends of the end mill are touching the work so I presume that everything is still trammed in.

@@thehobbymachinistnz I’d be interested to know if you ever get around to checking. With a bit of luck I’ll have one of my own soon and I’ll check it as well. I’ll be following your tutorial.

Bit late but I found it matters how you tighten head on column. Top bolt has to be tight tp prevent overhang making spindle droop then nipping up bottom bolt to stop vibration Edited to clarify how I tighten head to column bolts, sequence below.

@@1crazypj do you mean the two or three bolts that lock the head in place on the column?

@@freestyla101 The two bolts that lock head to column. I found that if I tighten top then bottom, mill is out of tram I'm sorry, I described it wrong in initial reply, correct sequence (at least for me) I nip bottom bolt, tighten top bolt then go back to tighten bottom its just about perfect. Really surprised me, I don't know how much time I spent (wasted?) trying to shim under the column base

Thanks for watching and your comments.
