With my pier built (pretty much) – I need a small bridge to bridge (pun intended) the gap between the land and the pier. In fact .. finishing the pier depends in part on installing the vehicular bridge. I copied the design from Army TM 5-51B Carpenter – Chapter 10 – Nonstandard Fixed Bridge
Here's the ‘Semi-Final’ .. plan.Went through my box of strip wood etc. and .. have everything I need. That's amazing!! I assigned each size of wood to a different layer and had Sketchup 'show layers by color' .. was helpful I think in figuring what strip-wood I needed.
.. and here it is without all the psychedelic colors -
I had the tread as 2x10 lumber and will go with 2x12 .. and don't have any 4x4 stock .. but .. have some weird 3x5 stuff which will work fine for handrail posts and knee braces.
Edit: Just came to me that I need to double the stringers under the tread. Works ..
I believe in the - "If you have it, use it" phrase .. so .. I decided to build a jig to assemble the bridge. One thing I had to get around is that my Proxxon mini-mill only has a X-direction table movement of just a bit over 5 inches .. so it's "adapt and overcome" ..
In the pic the brown represents the stringers .. the gray a mini-square and the white bits and pieces of Sintra®
With handrails done, I propped her in place .. more or less. I haven't finished the pier yet .. as I was wanting to get this bridge in place so I could see where the rest of the pilings etc. would go .. shrug. I make this stuff up as I go you know ..
Looks like I will only need two bents. On the far end can just be a cap sitting on a footing. Still need to weather etc. as it only has an initial graying
Pulled back a bit for this shot. Huh. Need to finish that fascia off .. plan is to curve it around that bit there. Way back there where I damaged the backdrop when I was arm-wrestling the layout into place .. prob where the Clever Model's Critter Shed will go.
