Oh Great and Wise C22 owners ...

I have been preparing to raise my mast in the driveway, for training, and came upon a conundrum. Reading the manual, in particular the part about using the boom as a gin pole, it mentioned a 5/8 x 3 'mast erection pin' that gets inserted into the cylindrical hole at the foot of the mast. Fine, I can go get one of those. However, I am at a loss to figure out what you do with the other end, the side that somehow attaches to the boom. As you can see on the photo, my boom end already has a fixed cylindrical fitting, that attaches to the mast with a clevis pin. This fitting is larger that the hole on the mast.



Is this the way the end of the boom is supposed to look? Or am I looking at this wrong?

Thanks!
Chris

You want to use the opposite end of your boom. The end away from the mast should have a hole for the pin. Scott has a great description with pictures and shows step by step how to raise the mast alone. I'm sure he will reply but it is still early on the west coast.

Hmm, thanks for the response.

The other end has a 6x1 inch metal spreader attached to a fixed screw, that comes out of the center of the boom end ...



Should there be a hole there?

Hmm, My 75 has a ractangular boom however my 76 has an oval boom like yours. I just assumed it was a replacement. I'll go check my 76 today and see what the ends look like.

The 75 has a hole in the outboard or aft end of the boom opposite the goose nech and toggle. IE if the boom is up and installed on the boat the hole is towards the back of the boat.

Hmmmm, Scott, my '76 has a rectangular boom also.

What's that pin sticking out of her boom for? And where's the goose-neck? The end away from the g'-neck should have the hole ofr the mast raising pin.

That pin is where the goose neck and toggle would hook up. I have the same pin on my 76 oval boom.

Looking at this issue more, do you think that I should ...

• Try to modify my boom somehow to act as a jin pole ( maybe try to make up a pin that fits around the screw? )
  
  Try to find a piece of metal to act as a jin pole.
  
  or
  
  Make up a wooden jin pole.

Do you think an 8' 4x4 wooden pole would be strong enough to serve?

For my 22 with the odd boom, I'm going to hunt down an aluminum pole for stepping the mast. I'llmake the necessary mods to that pole including eyebolts specifically spaced for stepping the mast. May even add lines specifically for that too.

I'd consider a 4x4 but I'm lazy and do not want to lift such a beast.


Just my two bits!

Heh, yea that would be best, but a shaped piece of metal of which is thick enough to resist the sheer load, and long enough to make a good lever, and yet hollow enough not to weigh 500lbs is hard to find . If I had a lathe I'd make a pin to thread onto that spurious screw and fit in the mast base and use the boom.

If that is the case, just go to the hardware store and buy a large partially threaded bolt with a section that is 3 inches of no threads. I used a dremel and a cutting wheel to cut of the threads and the head off the bolt. I used a stainless bolt. I then took a sanding wheel on the dremmel and rounded the edges of my now 3 inch long pin. I actually made two pins this way for lady Jo! Figured I'd loose one one day! I did! LOL! They work perfectly. I forget the diameter but you can measure that. For some reason 5/8ths diameter pops in my head but don't quote me!

Scott

Since a precious owner had modified my boom and there was no longer a hole for the 5/8 pin, I used a piece of 2x4 the same length. I drilled a 5/8 hole in one end and made a 3 inch pin from a bolt, like Scott did. The other end of the 2x4 has two eyebolts facing opposite sides. You might think that a wooden 2x4 would not be strong enough, but is is. The pulling force that raises the mast is transferred at the top of the board. Mostly the board is just in some compression downward. It is a bit inelegant, but it works.

Good luck with the mast raising!

I also use a separate jin pole made from an old oval boom i had laying around. I can break it down into two pieces to make stowing it easier.

I got tired of using the boom and also made my own from a 2x4. I did beef up both ends with roughly a foot of 2x4, but I don't know that it was necessary.

When using the boom, I lost one pin inside the boom. The pin was always falling out of the boom hole. It was a pain!

We drilled a hole through the pin and stuck a large cotter pin through it. No more pins in the boom!

On my C-26 I did not trust the boom as the rivets on the aft end were loose so I got a 10' piece of 1" black pipe and a cap. Drilled a hole for the pin and cut pipe 3" shorter than the distance from the mast finger to forstay chainplate and 2 eyebolts (jib halyard top and tackle of 2 double blocks to bottom and ratchet straps for bridles)
