I was sailing in a new spot - Lake Sammamish Washington to check the boat out before heading to Salt Spring island, Canada for the FFI race. Just after pulling the boat from lake I headed to a washdown facility. It was occupied by several boats. I was going to pass but then decided to back up and get in line. fI did not see the low hanging branch and snapped the mast right at the spreaders.
Practice piece.Trued up edges. Alum 5042 is fairly brittle.
This beef cake board was free for the taking down the street.
Routed a groove in it for forming in a press.
So the idea here is to create a sleeve and couple mast with rivets. But also pretreat the sleeve and mast interior with etch. Quickly rinse, dry and apply epoxy. Insert sleeve and start riveting.
After that is good enough install second mast section and do an alignment.
Spot holes and disassemble. Predrill transfer holes marks. Etch sleeve and mast again, rinse, dry, apply epoxy.
Couple mast and rivet complete.
Etch outer and rinse, dry. Apply section of fiberglass to perimeter and vac bag if possible.
All lines must be managed prior to connection for future routing. OK, here goes!!
Prep a hole pattern and reposition spreader to adjusted height after cutout.Transfer holes on mast to sleeve insert
Bonzolite Aluminum - um - solder? Seemed to flow ok. It appeared to be taking up some in the seem.
It did not take a huge amount of force to pop this off. Switch to JB weld.
