Part 1: Sketchup - Torsion Box Design and Layout
I have been working on the design of the Cabinet of the RAS for sometime now. I finally got the Sketchup done for the frame of the Torsion Box. I have been working on it for several hours this evening and have many more details worked out but that is gonna have to be for tomorrows blog. The outside frame is of 3/4” MDF and the ribs are 1/2” MDF. I could as easily go with 3/4” ribs. But I think I will have minimum deflection in this configuration. Anyone disagree?
Part 2: The Cabinet Design and Sketchup
Well here is the drawing for the cabinet base for my RAS. The design for this has been challenging as not only do I have to level the table to the Saw and its carriage but I also want to level the RAS Table to my Miter Bench. After digging around I found some leveling feet that will screw to the side of the cabinet and then be adjustable though access holes drilled into the shelf. This will allow me to level the Saw to its’ table then I will level the cabinet/table to the Miter Benc...
Part 3: Getting started with the case
As previously posted, I had worked out the details to my RAS cabinet using Sketchup. I started working on the cabinet this weekend and the reality of my previous work objected to the finest of my plans. With the miter bench not being sqaure, I have going to have to adjust my plans for the RAS cabinet. I am going to have to take an inch off of the width of the cabinet and the torsion box. This is so I can make the cabinet square. I will then have to set the cabinet into its place and scibe ...
Part 4: The Case work is done
Started working on the case this weekend and got it done this evening. Here is the Sketchup drawing of the case:and here is the final result:and here is the leveling configuration: I need to go back to Sketchup and redo the torsion box as I had to reduce the width of the cabinet by one inch.
Part 5: Torsion Box is started
I started the torsion box this weekend. This is my first one and it has been a learning experience. David Marks makes it look easy, but it is not. I got my work surface straight and level and started building the grid work. I quickly learned that brads are not a good substitution for finishing nails, as they like to follow a random path. I had to push on as SWMBO would not allocate additional budget for a finishing nailer. The gird work is done and I got the first skin on this evening. I hope...
Part 6: Testing the Assembly
Finished up the Torsion box early this afternoon, after the glue dried I laid out the mounting holes for the RAS Base and put in the threaded inserts (not allot of fun in MDF). I temporarily mounted the RAS base to the Torsion box and placed the assembly in the cabinet and the I place it in its home to get a look at if and how everything will go together. I am very pleased with how things are looking at this time. The cabinet is square, the Torsion box is square, and everything is fitting lik...
