@Claimdude - seven questions:

1. Judging from your photos, the Rockler version appears to feature brass or bronze bushings for the interface between the chuck carriage and the steel guide rods. As was discussed earlier,  the UJK version features bronze Oilite (oil impregnated) bushings. The advantage of these are that they provide continually lubricated operation while reducing to a minimum any play between the carriage and the guide rods. Are you able to discern any noticeable play between the chuck carriage and the guide rods on the Rockler version?

2. I note the Rockler version features a brass thumbscrew to lock the chuck carriage against one of the steel guide rods. I assume the use of a brass fastener is to prevent marring of the relevant steel guide rod. In practice, does use of the brass thumbscrew do an damage to the associated guide rod?

3. Do you have the capability of being able to determine if the guide rods are accurately parallel/coplaner/inline with with each other? If so, how are yours?

4. The first run of the 2nd Generation UJK-branded drill guide suffered from a problem with the rubber base which produced a wobble. Does yours suffer from this problem?

5. Assuming you have access to a caliper, what is the diameter of the guide rods? I'm wondering which size stop collar is compatible (since it should be a simple matter to acquire a second collar should two be desired).

6. The hex shaft connected to the chuck on the UJK version is Centrotec-compatible. It appears from your photos that the Rockler one may be as well. Can you confirm?

7. Do the graduations on the angle adjustment castings appear to be accurate and in agreement?

Looking forward to your reply! :)

Tinyshop,

1. The slide action is very smooth and there is a slight oil film left on the rods. Other than that I don't know what the makeup of the bushings is. If you know of a way of can tell for sure let me know.
2. The brass screw does not damage the rod when tightened on it.
3. The rods are coplaner, parallel etc as far as I can tell with a Woodpecker square
4. This one sets perfectly flat on the base. No rocking or movement at all.
5. The rod measures 13.83 mm or .544 in
6. The hex shaft does accept the centrotec chuck.
7. The markings are accurate and agree at least at 90 degrees which is the only way I gauged it.

I am not a huge Rockler fan but they appear to have done a good job on this item.

Jack

Just received the following response from Rockler regarding their version of the drill guide:

"The Rockler Portable Drill Guide has Self-Lubricating bushings. Additionally, this is not the same as the Axminster-Branded Drill Guide. Rockler's is much more substantial. It is larger in size and had a larger chuck which can accept 1/2" Drill bits. There are several other features including a 90° stop, storage holes, larger vise attachment, Easy-To-Grip Knobs and a quick lock brass knob which makes this a fantastic product which sets itself apart."

Not only does this appear to officially answer the question re: the bushings, it also points out the fact that the Rockler version features a slightly longer travel (8-7/8" versus 8.2") - meaning, I'm guessing, longer guide rods - a true 1/2" chuck (versus the 10mm chuck fitted to the stock UJK version) and, apparently, wider guide rod spacing (apparently allowing for a larger footprint optional vise).
