Brians Questions:

Hello guys,
Love the podcast. Thank you for your time and expertise!
Question on making drawer boxes and other situations where butt joinery is used. How much of a difference would it make if I do not use any glue and rely only on pocket screws / regular screws? Main reason I am asking about skipping glue is because I usually use 2 side prefinished plywood to make drawer boxes so unless I figure out how to remove the finish where the joints are, it will not really stick. 
Follow up question. What’s the rule of thumb on how to space pocket screws? Let’s say I have a drawer box that’s 12 inches high. How many  pocket screws would I put on each butt joint?

I’m building a very large display case for a museum, about 15 feet long and 4 feet high and 6 inches deep. Kind of like a giant shadow box. It will contain a canvas replica of the Shroud of Turin, with LED backlighting behind the shroud canvas and a ¼” glass front (2 sheets of glass with a seam in the middle). The back panel will be either 1/4" or 1/2" plywood. We will have legs under it to support the weight across the 15 foot length, as it will be very heavy once fully assembled on-site. Here’s my question; is it realistic to plane, cut, and sand a 15 foot long 6/4 board, about 6 inches wide?   Am wondering if I could realistically handle such a board, and if so, would it remain flat and straight over time.   Or, would I be better off making two 7-1/2 foot long boards and somehow joining them together to make one 15 foot long board. If two boards, what’s the best method for end-to-end joining of these boards to get a barely-visible joint and a perfectly straight assembly. Do I need to be concerned with sag in the middle if I have a plywood back panel? Mark

Guys Questions:

I have recently started using Arm-R-Seal and I am new to using finishes with long curing times. I have been prefinishing all my parts because I assume it's near impossible to get a nice finish after glue up. Is this correct? How long should I wait after applying the finish before glueing? Also, if the piece of furniture was for a customer, would you wait the full 30 days of cure time before delivery? Jeffrey Hughes

I teach a beginning woodworking class at a High School. I will be receiving two Bambu Lab X1 3D printers for one of the Engineering classes that I teach as well. I know that 3D printers can be very useful for woodworking and was wondering what ideas you would have to share for helpful tools or accessories that could be made using the 3D printer? Also do you have a specific website where you go to find premade tools and accessories that is trustworthy? Thanks in advance for any information that you could provide. Scott Kirkman

Huys Questions:

Hey it’s me again,
I have a 10” Metabo contractor saw I use for my house projects and finer pieces. It’s a quick and dirty saw that I can set up and knock down and roll into the corner. I love the wide table of it but it’s starting to feel wobbly when making cuts. Thinking of building a box around it to have out all the time and catch dust and shavings. Maybe on wheels? I’m no contractor so maybe I should just invest in a cabinet saw… love to hear thoughts. Ian

Hello,
I am getting ready to build a box beam to wrap an exposed LVL beam in the great room of our vacation home.  It's a horizontal beam with about 2" protruding from a finished wall (drywall).   The span is about 14', and the beam is about 4 1/2" tall.  I will be using knotty pine to create a 3 sided box beam with mitereed corners.    My challenge is that I cannot built and transport 14' beam, so I need to build 2 7' beams. Each end of the beam will butt against a wall, so there isn't much room.   So my question for you all is what type of joinery would you use to seam the 2 beams together on-site?
Thanks, and I appreciste what you all are doing for the woodworking community. John
