Sooooooooo...BugR's table is cool, but the OP's table was a death trap? I'll never understand you weirdos!
That does look like a nice platform though BugR.
Let's look closely at the two tables:
Exhibit 1 (OP's original table design):
"Glued & screwed. Only things left are the leg supports, carpeting, paint and levelers (they will take the place of the casters). Used 2 pieces of 1/2 plywood (glued & power-nailed together), 2x4's & 2x2."
"Total height at finish will be 27"."
Exhibit 2 (BugR's table)
"Solid laminate top, bolted to 2x4's running the full length, 4x4 legs and 6" solid wheels.
Table height off the ground is 18". "
Things wrong with Exhibit #1:
Table is too narrow for the height. Ramp is too narrow for safety. I'd want a full width ramp.
1/2" plywood is just too flimsy to support this kind of weight per sq in. 3/4" would be the minimum for this weight load.
Drywall screws were used for assembly. I know the glue is the primary attachment mechanism, but drywall screws are brittle and shouldn't be used except to hold up drywall. Use lag bolts or drill and use through bolts and nuts/washers
Legs are too too tall for the width, whole thing looks like it would tip over sideways with the bike's weight on it. Longer legs allow too much leverage on the table top to leg joints in the lateral direction. Diagonal bracing was intended in one direction (fore and aft) but there was no side to side bracing. Those long legs would fold sideways.
But most importantly, did anyone else notice that BugR's bike already has some kind of a wild crash frame surrounding the bike for the eventual table crash?
