All lumber was left over from a pole building I put up , with used lumber from a wind damage building. I use the 6 X 6 pole stubs for the legs. Cut 4 of them 30" long. On one side of each post I cut away a 2 X 6 notch to hold the top side rails. With them cut to the 74" length, the side rails were screwed to the post square with 3" deck screws. I used a 1/4" impact driver to drive the screws through pilot holes in the 2 X 6.


After the two side frames were built I positioned them in the shop and attached the 2 X 6 X 40" end pieces. Then the top planks were cut and attached.



I plan to pull the tractors on front first so attached 3 - 2 X 8 planks on the end the rear of the tractor would be and 2 planks on the front end. The rest of the plank were laid loose for removal as needed.


At this point I do not think any bracing will be needed as the winch will be anchored to the end of the table and the pull will be against the ramps. It is a dead solid work table. I have 4 wheel chocks to block all four wheels while the tractor is on the table. No nails were used. Everything was attached with 3" deck screws with pilot holes in the piece being anchored.
2 X 4's double can be substituted for the 6 X 6 post. but I would add cross and lengthwise bracing using this method.
