Here is a drawing I made using the high end CAD (Computer Aided Design) system we use at work (I was bored and had nothing to do for an hour or so)
Its the tying bench I use and I bought this many years ago when I lived in Colorado. It is for a right hand tyer but all you have to do is move the vise attachmet to the other side of the bench.
I did not provide any dimensions for the spool holder dowels as I dont like them or even use them. It will not be that hard to figure out where they go and at what angle to place them at.
I also screwed in simple cup holders on the right side of the bench for my hackle pliers.
A magnetic strip below the first row of holes was there when I bought it and theres one by the vise c-clamp.
You will notice that I did not dimension or provide the size of the holes in the bench. I decided that was up to whoever wanted to male one. Just measure the sizes of your tools, cement bottles etc and go from there. You may want more holes, less holes or whatever. Wood for this project is up to the builder.
Heres the real one
