I am in desperate need of the 3/8" x 1 1/2" clevis pin to attach the keel cable to the keel eyebolt.

I ordered parts from CD but of course the pin was back ordered & hasn't arrived yet.I need the pin before Monday's splash date and so far none of the local retailers have stock in the size I need.Can I use a different length pin and would it matter if the size of head is different?

Remember... a longer pin can always be made shorter!

A few minutes with a hacksaw, file, a 3/32" (or similar sized) drill and Bob's your uncle. Vice and drill press would be handy or a steady hand with a drillmotor. File a slight flat spot where you want the cotter pin hole and it will be a lot easier to get the hole started.

Size of the head shouldn't matter as long as it doesn't slip through. Not sure why a slightly longer pin would hurt anything either. Or a bolt with a locking nut/cotter key.
All it has to do is stay in there.

I would think that a long 3/8 stainless hex bolt would have enough unthreaded length under the head to allow cutting off the threaded end and drilling a cotter pin hole. Should work OK.

I found one more place to check that actually carries Catalina Parts.If they don't have the clevis pin I will go ahead and follow one of your suggestions.

Thank you for the great ideas!

"Bruce: Have you actually tried something like this? "

Yes, I've drilled a fair amount of stainless including cross-drilling bolts. As a young man I worked in a machine shop and later on as a millwright/welder. I'll have to admit that I've burned up my share of bits while trying to figure stainless out.

All that said, on holes between about 1/8" and maybe 3/8", using a good quality bit and an aggressive feed, things usually don't go too badly. I use 'rapid tap' for coolant/lubricant rather than conventional black cutting oil. If you're using cheap imported bits, all bets are off.

On bigger holes, I do feel your pain. With home equipment it's tough to get enough feed pressure to keep the bit cutting. One guy has to really yard on the drill press (sometimes using a cheater) while a helper keeps a stream of coolant going. The cutting angle of most standard drill bits aren't quite agressive enough for stainless either... which doesn't help matters.

You get a couple good holes... then hit a hard spot in the stainless and burn up.
Been there, done that... with a 3/4" bit it hurts the wallet too.

I've also made a few masthead clevis pins from SS bolts by cutting and drilling.

Another option is to simply use a SS bolt with nylon locknut. You could trim off the excess threads to reduce weight and give it a cleaner look. Just be careful not to tighten it, but rather leave it loose like a clevis pin.

I discovered this company:

http://www.mscfasteners.com/materialsearch/mscproducts/stainless-pins.html

They are very reasonable, but took a few days to deliver. It was
practically the only place I could find the pins used at the
tack and gooseneck on the C25 which are 1/4 x 1-5/8 & 1-3/4.
Very hard to find those lengths in 1/4 dia. If you can find other
companies that make them they require wholesale or bulk orders.
CD has the 1-3/4 length but wants 8 bux for one. I ordered a few
from MSC. Even with the shipping cost it really beat CD price for one.

Thanks Paul... Hmmm... I wonder if a 'where to find' index on the site would be useful?
(But only After summer's over so Spike can enjoy some quality boat time)

Late yesterday I found a small local that had the clevis pin. I didn't have to use plan "B" but I will definitely keep all of your suggestions for future reference.Thank You!

I also think that a "where to find" index would be excellent!
