Does anyone have formulas for calculating wood strength?
I am making a table lift, consisting of three pieces of wood/steel, first
piece with bushing t in the middle of it, position toward one end of a long
threaded rod. Second piece, with threaded nut wielded/epoxied, etc sits only
2" above third piece. Third piece has casters. Seond and third piece will
stay in line using two rods vertically between the pieces. Three pieces
extend across table width on the inside of the table. Point is no wheels
seen, mobility when necessary, and no casters when doing actual work.
Goal is to turn threaded rod, which extends from above first piece, through
second, and then simply sits in a bushing drilled in the third piece.
Turning rod raises or lowers third cross piece, which has the casters, due
to presence of nut on second piece.
Question is whether a hardwood, like OAK, would support the weight (500 lbs
or so) or do I need to fashion a metal solution. There would be one of these
3-piece lifts at each end of the table, meaning each would need to support
240-300 lbs of weight.
Hope this is clear enough for an answer...thanks...
