mounting oarlocks; screw vs bolt
I'm top mounting oarlocks on three inches of wood. I understand wood screws could eventually come loose and that machine bolts might be a better choice.
The other thing is the close proximity of the screw hole to the larger hole for the neck of the oarlock socket. I'm thinking if I drill the screw hole too big the screw will be weaker and if I drill the hole too small I might split the wood because it's so close to the larger hole.
All this leads me to think a bolt hole is probably the way to go. Unfortunately the silicon bronze bolts I've found cost as much as $5 a piece and fender washers as much as $25 (can you believe that?). For four stations that really adds up. I've intentionally done some stupid things in my life but this would take the cake.
I guess what I need here is a #10 or 3/16" countersunk bolt 3 1/2" long. What material?
Everything is practice
