Gary Katz, Dean of Finish Carpentry, University of Hard Knocks. Thanks so much for being one of the pioneers in the business of finish carpentry instruction for the then emerging digital media market. (Yea the tapes were analog but I'm talking big picture here) Even though I had the benefit of a structured apprenticeship, the fine points and systems approach you teach weren't developed as much as they should have been in my training. So when I started production finish carpentry in the tracks in California your books and tapes were a terrific investment. They imparted the knowledge and confidence that allowed me to become a successful specialty installation contractor. I'm so happy that you are releasing them here on YT to help the next generation of carpenters master this complex and demanding area of the trade.

Love your videos, bought the dvd set a couple years ago, and now I’m happy I can watch it all on my iPhone. My wife tracked down a copy of your door hanging book for my Christmas present - thank you for the education Gary!

[OQureshii]

Your videos were a huge help when I changed all my exterior doors. I can't thank you enough for the videos!

[shaffer]

I’ve been watching you for quite some time. I’ve learned a lot, and am thankful you continue to teach. Just installed a double steel firedoor and a single pre hung. Thanks to you I was prepared and all went well!

[henrysara]

Thank you again, happy to hear you back on here, Keep it up.

[dementedbuddha]

Thanks for this. Last year I had to diy a bunch of doors done horribly in my house. Your later video on this subject was the only one out of an uncountable number I watched that really worked for me. I had to watch it more than a few times to get it, but I'm pretty sure you have the only videos on YouTube that properly explain how to install an interior door. It's a real art.

[oddassembler]

This is a great legacy you are leaving, especially the Finish Carpentry stuff as that is rare to find thorough information on.

[wadesipes]

Thank you for this so much, I’m currently trimming out two house and your videos have helped me from falling flat in my face

[technopreneurialminds]

Whao! This is exactly what I need to grasp the technique of hanging a pre-hung door. Thanks a billion for your time and effort in putting this training video out.

@ 38:00 ....SHIMS....it's best to put 2 shims opposing each other so the jamb moves perpendicular to the framing and door...with one shim only, it acts like a WEDGE, causing the jamb to "twist" inconsistently away from the framing.

[ryanern]

The 5th shim was a game changer for me a newbie.

[jamess]

True Master of this Genre! I stumbled onto this video to find an answer related to hinge bending technique you show in a different video but couldn't find the answer in this series as well - could you potentially share why the "spread" function can't be achieved by bending the knuckles as you do with the "squeeze". Isn't that in essence what it's doing is bending the knuckles when you force the nail set in there?
Thank you!

[mnight]

Man i wish i could have shadowed you on the job. I would have kept my ego in check and listened to everything you had to say

[asuhayda]

So grateful to you for sharing your knowledge! I just wish you had a few more videos. I've watched and re-watched but I'm still not feeling confident enough to tackle my exterior door yet. I just ordered your book hoping that will give me what I need to feel better about what I'm about to do!

Did I miss where you address the header not being level? You mentioned it briefly but I want to make sure I understand how to handle this. Is this just fixed but shortening the jamb length?

[mikevogl]

What if the PLANE of the wall isn't plumb: Should the jambs be plumb and proud of the drywall at top or bottom, or should the jambs be flush with the drywall on both sides of the wall but not plumb (and will the door then fall open if not latched?)...

[scottkrieman]

Good video and I like your pants where did you get them? Looks like you can install pads at the knees and has built in tool bags.

[Smabe]

It would be opposite for installation on top of flooring. You'll want to start at the LOW point of the house so that you have material to cut off to level jambs across the house.

[RobbieWilkes]

Great video! However, I can't find even one single video that addresses my situation, which I think is crazy. I can't believe I'm the only person that has this question... or maybe I just don't know how to phrase it properly.

We just bought this house, with a finished downstairs area, that is almost its own apartment space, with 2 "bedrooms" and a full bath in between. My wife and I are using one of the rooms as our bedroom, and the other as our office. The only problem is, the entrance to the "apartment" is an open cased frame, 32" x 80", with smooth sides (no door trim), which means our space is open when someone walks down the stairs, or comes in from the garage.

So, I'd like to add a door there, but I am clueless as to where to begin. Is the trimming necessary? How difficult is it to add hinges & lock plates? I've looked at some 32" x 80" salvage doors, online, listed with hinges and knob, but not sure if that would be too big, of if the way it was previously hung would affect how I could use it?

I know these may sound like dumb questions for the "handymen" out there, but I'm just a computer guy trying to figure it out. LOL!

[diybasics]

Great videos Gary. I had a question regarding the correction of crossleg on double prehung doors. You show moving the hinges in or out to correct, so on an 8-0 door with 4 hinges, do I need to move the bottom two or three hinges to make the correction or do I just start with the bottom and take it from there. Doesn't seem to flex much with just the bottom hinge off. Thanks

I’m a little confused on plumbing the door from interior to exterior side. Looks like the door just needs to be flush with drywall, but what if the wall is not plumb…? Wouldn’t the door close or open on its own. Walls aren’t always plumbing right?
