« Part 4: Book Matched Walnut Doors Part 5 of James Krenov Inspired Case series Part 6: Hanging and Fitting the Doors »

In this video, I cut in the mortises for the knife hinges in the bottom and top of the case. Then perform the final glue up of the cabinet. I also make a very big mistake along the way can you guess what it is?

If you have any questions, please let me know, as I would love to hear from you. Thanks for watching!

I am guilty of not commenting on videos, although I am super appreciative of the folks who spend the energy and time to offer their knowledge in such an accessible fashion. Please don’t let the lack if comments discourage you!

Thanks Mark! Making these videos makes the project take 3-4 times as long as it should, and it’s nice to know when someone appreciates the extra time and effort. I am not “fishing for compliments”, just making sure all of you out there are awake! HaHaHa.

I’ll show my lack of cabinet making experience here by asking what your mistake was. I have to admit that even with the captions in the video I am not sure what the problem was. Was it something to do with the 1/16th offset?

Mark, it definitely had something to do with the 1/16th inch offset. You’re getting warm!

Should the offset from the case have been set to allow for the thickness of the door beyond the edge of the mortised in knife hinge blade and not 2 times the 1/32 gap between the knife blades? I was wondering why you’d need several of the 1/32 spacers.

That’s it exactly Mark. I should have offset the hinge 5/16” from the bottom and top of the case to position the hinge in the middle of the width of thickness of the door.

Why do these steps seem so logical when we are doing them but then when we finally ‘see’ them it is usually just after the point of no return on the way to screwing up? :-)

Very glad you showed the real video and didn’t gloss over the measuring glitch. Back in my teaching days I would use opportunities like that to illustrate the reality of the job environment and stress it was how they fixed the problem that was more important than the fact an error was made.

Guy, your videos are excellent. I really enjoy watching your builds.

I had watch a few time before I snapped to the mistake. I’m sure you’ll devise a cleaver way to fix it.

Thanks Nicky. Unfortunately by the time I noticed what I had done, the case had been glued up. I just went with the hinges being in the wrong spot. When I did hang the doors however, they still work fine. Only someone really looking for a mistake would notice they were cut wrong.
