Here is another item some of us will be needing to get the RT off a building table, RAMPs. What do YOU feel should be the bare bones to support the weight of moving the RT? I am thinking ramps 12" wide x at least 8FT, so maybe 1/4 plywood, sandwich between 3, 1"x2". What are your thoughts???

2×4's I would say should be a minimum if you are building them with 1/4 inch angle along the end that hooks to the table.
I would also brace the angle with welded plates that run at least 6 inches along the 2x4's.

I took a different route for ramps(if i ever need them). I bought a simple harbor freight trailer and modified it for my purposes. I bought it used for $200 somewhere about 6 years ago. The trailer is 48" wide and 96" long. Long enough to fit my Ryker except for the front wheels. For my ryker or my homebuilt trike to fit i will need to add some 8"x24" frame extensions and panels to the back of my frame so the ryker front tires will sit on them. The reasoning i made to use this trailer is because the hitch arms are bolted to the frame about 1/4 the length of the frame. This lets the frame tilt so the rear frame will sit on the ground and you can adjust the height of the frame to match up with the building table with a small bottle jack. With the hitch mount frames well inside the 4 ft frame width, and a open framework under the build table the hitch can slide under the build table. I put 1 inch porch pine decking on it. Later i used more decking to make side panels 24 inches high. I also made end panels to be able to box in anything in the trailer. All of these panels are hooked to the trailer frame with steel boxes made out of steel to fit standard 2x4 wood framing boards. Bolts were used on the flooring and deck screws were used on the siding to attach them to the 2x4 wood framing boards. pulling pins out of steel brackets bolted to the frame ends lets me pull all the sides off the frame leaving the floor as a platform. Tomy, perhaps you could do without the flooring and sides. perhaps some steel square panels mounted at the back for the front tires and a 12 inch wide 16 gauge steel channel in the center for the rear wheel. The trailer could be used double duty with 4x8 ft 1/2 inch plywood that fits frame since there are 5 rails across the frame. Even 1/2 inch plywood would last for a good while before warping. The Harbor Freight trailer  Here's my parts trailer i bought for $60 so i would have some 1/4" steel plate to make things with and some free 4 inch channel too boot.  |
