I have a question regarding plans made by Pres Bruning. I like his work but am unable to find plans for things like ribs and formers. Did he publish a separate sheet for items like this and if so, where can I find it. I am considering his plan for the Northrop Gamma.

Bob...Home Depot/Lowes has a number of smaller magnets used to close cabnet doors etc.  You get several in a small package. 

Unless you're gonna build a fuselage longer than 32" you should be in good shape with that size board. Wings can be built in sections so even a 6ft wing could be built on that board but the fuselage length is the limiting factor!!!

I have used both methods. Since i can get sheet metal for free (when i remove old steam boilers) Amazon ordered magnets.
It is a learning curve. Since my wrist and thumb fusion i put the board up and went back to pins but once i gain strength back i will use the magnet system on my bigger builds.
Its all what you get use to and like. I did make some jigs for the magnets which were a big help but the same for my pins to.
In the end we just keep building

There is a learning curve for those of us used to the pins and ceiling tile building boards.  There are a lot of pluses as well, when it comes to building those box fuselage structures.  The magnets do help in keeping things vertical.  Just a hint, if you go to one of the big box home supply stores they have an assortment of smaller  and various shaped cabinet magnets for holding the doors closed.  I bought a bunch of long narrow ones and their ability to hold things in tight places and not so attracted to the other magnets.  You might want to give them a try!

Now, I can move the free flight building board around my workshop and bring it back to my large, motorized building board with other, larger projects pinned to the homasote surface.

I'd ordered the Little Richard kit from Easy Built and started my use of the board. I found that the melamine coated board has the advantage of resisting damage from spilled glue and dope. The Scotch mounting tape raises the edge of the sheet metal enough to allow easier grabbing of the magnets before using them to hold down parts. I keep them handy around the edge of the board.

I found this mounting tape to be ideal. Alas, I needed two rolls of it to tape to the shelf and created equally-spaced "lanes." This tape is aggressively tacky and once mounted you will find the sheet metal is pretty much permanently mounted. The good news is that the sheet metal is evenly supported and there are absolutely no "dips" or "valleys" anywhere.

I decided to keep the bolt heads flush with the bottom by drilling with a 3/8" forstner bit and getting the depth just right with my drill press. It's nice when things come together.
