Onocoffee... how's it look? Nice and sturdy?
It's... pretty good.
If that sounds hesitant, that's because I'm not sure yet how I evaluate it. My only comparison is a Milescraft Drilling Jig that I got from Woodcraft back in 2024 when I was boring holes in my workbench. I used that to bore 86 dog holes in 1.5" plywood with the CXS12 and a Fisch 20mm Forstner bit. That did the job.
The MB-40 seems more stable but I find it a bit wobbly - though I only used it solo. I did not use the accompanying rails and guide. That said, the 20mm dog holes (that are 19mm deep) look straight and vertical, so that's a positive. On board dust collection is great - though there were a few times when the chips got a little larger and clogged the port.
A couple months ago, when I knew I was going to get the MB-40, I went out and got the T-18+3 since the only Fast Fix drills I had were the CXS 12 and an older TXS 2,6. I used that today to bore the holes with a 1/2" chuck and a Fisch 20mm Brad Point bit with 1/2" shank. The worktop is made of cherry, maple and walnut but I thought the bit would bite a lot quicker, so the bores took a bit longer and were more difficult than I had anticipated. I got into a routine of starting the bore in 2nd gear and at full blast until the bit started cutting. Then, once it seized, backed it off, switched to first gear and continued the cut. It would seize depending on how quickly it was biting and if I had more pressure on the drill.
What I was concerned about was racking. The Milescraft racks a little, which meant that some of the holes in the main workbench are slightly skewed. Even in the moments when I felt like I was pushing down unevenly on the drill, the MB-40 seems to have maintained verticality. So, in this case, it's quite sturdy - and at no time did I ever feel that it was janky. The Milescraft can have a bit of that janky-ness but it cost me $42. Comparable drill guides from Rockler and Woodpeckers are considerably more, and I believe the Woodpeckers is more than the MB-40. I do think the MB-40 has greater versatility, with the exception of the lack of doing angled bores.
I need to use it more to really get a feel for it - as well as read the instruction manual thoroughly. I glanced through it and it seems there's a bit of functionality that I don't know yet. I like the LR-32 compatibility.
One thing that did really irritate me is that, sometimes, the drill would detach from the MB-40 after the bore. Perhaps it's the way I was holding it or moving it, but the locking collar would unlock and as I would lighten my pressure, the drill would come off the MB-40. It's not difficult to reattach but it is annoying and started making me concerned about letting go of the drill after the cut.
Here's a pic of the results. I jigsawed the slots but everything is still rough cut in the pic.
Oh, and in case anyone is curious: I plotted the grid by hand with a pencil and ruler.
