I spoke with Craig about the bearings he used. The video shows V-groove bearings p/n 630VV found commonly on ebay. Before talking with him, I had bought the RM2-2RS bearings and discovered that these are much too small for anything close to 3/8" tubing; they might be ok for 3/16".
Pretty easy - the bearings are V-groove bearings I bought on ebay. The base is a piece of 4" channel. The rest is pretty much as you see, drill and tap a set of fixed holes and add a set of bearing mounts that move.
Do you happen to remember the bearing sizes you used? I've been on eBay looking for a potential set for my own tube straightener and I'm considering using the RM2-2RS groove bearings as they look very similar to the ones you have and by my math they will accommodate 3/16" - 7/16 tubing. Another question I had was what did you use to cut the square slots in your channel and what did you use to mount the bearing to the angle iron? I'm getting ready to replace all of the brake lines on a couple of cars with nickel-copper tubing and I want to start with straight pieces for ease of layout and keeping my bends on the same plane. Hopefully I'm not asking you to give away too many details of your hard work but so far yours is the most professional looking of the bunch that I have viewed.

thanks, i'm trying to make this for my final project
I don't suppose you remember the part number of the bearings you used? Or the dimensions? Well executed straightener btw
i would apreciate a tutorial if you don't mind
love the design. do have any plans available?
No, sorry - easy enough to work out.
Nice tool. Can you show us how you made it?
Nice machine. Will that work as 1/4" OD shaft straightener?
It should work. You'll have to try it and see how it works.
Craig Coburn Thanks. Will give it a try. BTW what are the dimensions of the channel?
What are the make and model of the bearing
