Cool! I don't think you need to add any metal to increase strength, but it would provide additional damping simply from the added mass. The heavier the better with one exception. If you were to move the mill, a filled column, say with lead wheel weights and epoxy, would add a LOT of stress on the bolts {and your back}. I've always wondered why the connection between the column and base aren't substantially wider and with more screws. At some point, the column would, for all practical purposes, become part of the base. Not only that, the tramming would be much more precise. Glad I found your channel!
Yeah, I'm trying to balance weight with performance. I actually just moved this Taig mill from my dayjob to my apartment living room 1 month ago. The apartment I had to go up 2 flights of stairs. I ended up leaving it all assembled. It was about the limit of what I could carry up the stairs by myself.

Of all the ways I've seen it done, my choice would be 3 set screws to tram the column and channels to inject epoxy between surfaces to perfect contact because I believe it may be important for vibrations.
Thanks. What would you do for clamping? Would you use 4 bolts? Or 3, one on top of each leveling screw? I have to figure out how much the epoxy shrinks once it cures. I think the clamp screws might need to be tightened after curing, but I'm uncertain.
@@tugrulcagr7640 Yes I did, and I read all 400 or so comments on it! ha ha. The diamond paste he used has a distributor close to me, but I have not bought any yet.
Can you please respond to this , I'm currently making a vnc machine ( you can check my channel), I milled all my big part and I was wondering if a filed up them with epoxy granit (inside all my metal extrusions) there I any problem of dilation of the epoxy who could make my surfaces not flat anymore ?? thank you in advance
Hi, I just visited your channel. Nice work! IMO, your castings are large and strong. I don't believe filling them with epoxy granite (or anything else such as concrete) would cause any deformation. This is only my opinion, I don't know it as fact. I did not have any deformation issues on my filling. I also know several other channels took off-the-shelf hobby machines made of cast iron, and filled their column and base with epoxy granite, and had no reported issues.
@@ThomasLe_G If you stop the video at 1:03 min it has a paper with the ratios I used. I made about 5 different samples (shown in an earlier video) and settled on this one. It worked ok for me, but it was not super important it be strong, since I had a steel frame around the mixture. It looks like you are in a similar situation with your frame design.
Good job man. I just finished filling my 6060 gantry frame. About 600lbs of epoxy went into the base and the bed

I also like the idea of adjustment set screws and then injecting epoxy.
@@nickp4793 Hi Nick did you watch Stefan Gotteswinter's video "Tramming a milling machine with epoxy" ? He uses a speciality epoxy.

yum...

@@nickp4793 okay thanks a lot for your request , do you know the proportion ? I heard it is like 90% rock 10% epoxy

@@nickp4793okay yes thank you a lot ! I have done some calculs and I have almost the same pourcentage of epoxy resin who is 15%
