I'm happy to have found your channel you have basically answered all my questions and concerns about using a mag drill for line boring. I need to get my pivot on my tractor repaired has about 3/4 inch of slop in the pivot so it's good to see a mag drill working to drive the line boring bar mine is at least variable speed just have to turn the end and cut the flats for the Weldon coupler. Im just not sure if I should weld up the bearing holes then line bore them or line bore first to make the holes round and over sized and make insert sleeves to fit oem bearings at least this way the next time I have to do this all I need to do is knock out the sleeve and turn another and press it back in not sure what is better i do know that trying to turn welded material can be a problem.

I don't know if there is a fixed relationship between the holes you bored and the other pair of holes, but if you had longer plates you could lock into those holes and rest assured you were the correct distance away and only needed to adjust "vertically." You would also be parallel to their centerline if that matters. But good stuff, i enjoyed both videos.

Perhaps you could have some kind of thumb screw on your tool calibration clamp so that you could set it against your tool before you loosen it then you could tighten it to adjust your tool. This would at least give you a positive stop point to hold the tool against while tightening you grub screw. If that makes sense. I could draw it and maybe make it clearer.

Hi. This is a great video and great bit of work. I have been thinking of building the same setup for a while. I bought a bigger drill with slower speed settings. I have yet to get a bar setup. I was thinking 50mm bar but your size would probably be better to start with. What thpe of bar is yours? I would be concerned about welding when the magdrill is connected to the setup as i think it could damage the magdrill. Did you machine the end of the bar yourself to fit the magdrill?

Hello. Thanks! It’s a great cheap and effective way of getting the job done. I made the bar myself and yes, i machined the end to fit the same as a standard mag drill cutter. It’s difficult to get the plate the drill sticks to in the right place without having the drill already stuck to it.
