Spreader repair
Hi all,
I just bought an old Chrysler 22 in bad condition. I have fixed most problems (hull, deck, tiller, keel ++), but are now looking at the rig. One of the spreader is broken. This is the mounting to the mast. Is welding a proper way of fixing a spreader? Is there some place that sells spreaders. I also question the condition of the mast. Is it common to replace mast on sailboats? This boat is from late 70s. thanks! Haakon Dybdahl |

You left us to guess the material of the spreader. I expect it was an
aluminum extrusion. This can be welded, but without heat treatment, it is likely to be considerably weakened. Better to get a length of fresh material from industrial sources.

Thanks. Your guess i correct, I belive the bracket is aluminium (since the
mast is aluminium, and the spreader itself is aluminium). The broken bracket might be loosened from the mast, and after reading about "heat treatment" on the Internet, it should be no problem to do that with a tourch or something.

If your mast doesn't show any signs of heavy pitting under the fittings and no cracks, then you should be alright.. I just finished build an Ingrid 38 and I put in a used mast that is almost 20 years old and has been to the Bering Sea twice. I couldn't find any defect in the mast, other than some pitting under the winch bases and since they were on welded pads it didn't effect the mast strength. -- My opinion and experience.

Still guessing somewhat, that the broken pice is a bracket, not the
spreader. If the bracket was cast, it should weld without heat treat. If it was an extrusion, replace, or weld and heat treat would be the 'proper' approach.

Thanks for all the help! I got one more answer by email I would like to
share with whoever might be interested: "I had a Chrysler with the same problem. We drilled out from the base to the rod. Tapped a thread and installed a machine screw with loctite. No problems for my four year use after the repair. I believe the vessel is still sailing." pmg "Haakon Dybdahl" wrote in message ... Hi all, I just bought an old Chrysler 22 in bad condition.

Haakon,
Go To: http://www.geocities.com/thetropics/cabana/3135/ there is a wealth of information available there. I happen to have one in my backyard, but it is not mine.

Haakon Dybdahl My SC22 mast had a steel through bolt mount for the spreaders, but alarmingly, did not have a compression box inside the mast. I lost that mast in a race, when the shroud tension in a gust squashed the mast. When I built a new mast from an aluminium extrusion, I cut a piece of square aluminium tube and slid it inside the mast using chimney rods and tape. When the spreader bolt was in the tube, I pulled the rods out, tearing the tape. I put in 2 pop rivets located so as to ensure the compression box could not escape. -- Terry K - My email address is MY PROPERTY, and is protected by copyright legislation.
