Al,
I see back on Dec 31st a guy named Mark Boyce wrote this,
"This is the first I have seen your layout build topic. You have made great progress. I like your method of building track risers out of foam. Also, I am glad you got a new job even though it does tire you out. Thanks for sharing."
After reviewing what he was referring to, I agree with Mark! I like your method a lot. I have a shop vac, but need a table saw as I plan to build a new 12 x 12 layout next year.
Thank you for sharing!!
