Dennis Hill sent in these pics of his patio umbrella fixes.
The fixed umbrella
"2 of the 8 ribs supporting the umbrella canopy were broken in the middle where the lifting ribs were attached. I milled the broken rib ends square and made inserts to fit inside the extruded alum ribs. Then I secured them with screws. The lifting ribs could then be remounted to the new alum rib inserts."
"The umbrella column was broken clean off where it went into the patio table. I milled the column off square and then turned an alum insert to fit up inside the original column and down into the base support tube. I then constructed a small spring driven push button in the insert to allow the umbrella to be locked in a specific position within the column. The new column insert was attached to the original column with a bolt and lock nut hidden under an existing plastic shroud."
