I'm about to purchase a miter saw.  Just using it for benchwork and some basic home projects.  Would a double bevel be worth the extra cost?

Also, is a laser guide a good choice to have?

I'm about to attach 2" foam to 5/8" plywood. I've noticed a lot of folks seems to use Liquid Nails for Foam but I'm think of using silicone caulk instead. Any comments?

I acquired a Walthers  N Scale Motorized 130 foot Turntable on a hobby shop closing special with the intention of converting it to a 70 foot HO turntable which I need for my Port Costa roundhouse scene. I just measured it and it is only 69 scale HO feet but that will do for the wheelbase of the HO SP consolidations and moguls which will use the turntable.  The prototype pit for the Port Costa turntable was quite shallow and the plastic pit will work OK. 

I have been wanting to write this for a couple years now but didn’t have a good picture of the concept!  Recently I needed a bridge in a spot where the railroad existed and had to cut out a section of my spline sub roadbed. I was wondering what I would do with it.  Sleep is a great place to create.  I picked up the cutout section and it came to me that I had what I needed to show you all what I did!  This method is very strong and light at the same time.  A constant humidity environment is essential however.
