I am Northern Lights,... northern_lights is not me, that person came long after me. When you post your user name is underlined and these two look the same. That has confused some people. The computer does not differentiate the capitals but does que off the underscore!
Plasmaman found these, looks like the real McCoy:You may want to contact the mods directly, I doubt they will see this post....but, what is the description of those type of bits? I never saw one like that before, and don't know what to call them when searching.
Another possible suggestion to increase the rigidity occurred to me as I was looking at your pictures.That is what the floating second bearing allows me to do. I can move it and use the lock screw to secure it. The distance from that bearing to the cutter is the most minimal, I can bring it up to the point the shart starts to flare. That added the rigidity. One test run was done before I added it and it was obvious the shaft had vibration and wobble so I immediately added the second bearing. I aligned it to the original bearing on the shaft then soldered it to its carrier.

I am assuming you move the extension shaft lengthwise through your bearings as you cut, so at some points, there could be a fair amount of distance between the mill and your second bearing. One idea I had while looking at your pictures would be to add a third bearing on the shaft of the mill itself, between the mill head and head of the extension shaft. If you let the square side of the bearing float on the square shaft, instead of being fixed in position like your existing bearing, it would always be supporting the mill at the minimum possible distance for minimal flexing. And the distance between the mill and the bearing would always be the same so whatever flexing there was would stay consistant as the mill is moved lengthwise through the light. This might produce smoother results.
I am thinking about building one of these rigs myself. I already have the cross slide table sitting around unused. I bought one for a benchtop drill press and it was too large to use.
No, it is time consuming and you should see the hole I bored through the last tube I was working on. It is easy to make a mistake if you are distracted.That is sweet man You interested in some work ?

LOL? Just keep laughing, mine is the last laugh!LOL! You may have invented a new heat dissipating system!

As I promised when I tire of this contraption and its evil rituals I am sending it to dwell with you; it has an appetite for Mag Instrument aluminum. One 3D = One baggie of aluminum chips!
You can handle the fan mail.
One thing I noticed is that in many cases a quad-bore will also handle tri-bore needs too, that is my tri-pack of A size (18mm) would slide into the 4 bore. It is a shot at a universal host.
