Are their good ways to refurbish and reinforce wooden step ladders? I don't mean antique step ladders, I mean mass-produced ladders that are 10 or 15 years old with none of the wood cracked.
The big box hardware stores in my area no longer carry wooden step ladders. (The fiberglass and metal step ladders may be better than wooden ones, but I've never tried them.) Some of the step ladders that I have are getting wobbly, but none of the wood is cracked. I've tightened the threaded rods, but something further needs to be done.
I thought about using angle brackets and screws. However, I suspect that if this was a good way to reinforce a wooden ladder, they would be made that way in the first place. I worry that screws and a rigid brace would crack the wood as the ladder is used.
