This winter I intend to mount a Steaming light/foredeck light combo to my mast. Can anyone tell me the procedure for doing this? From what I hear drilling a hole in the mast for the wires won’t be a problem affecting the mast’s longevity but screwing in fasteners would be. Therefore, I must glue it to the mast. What is the procedure and the recommended glue? Do I grind off the white outer finish of the mast or just rough it up?

The forestay attachment point/halyard box is an aluminum fabrication
riveted to the mast. I would consider fabricating a light bracket
and drill/tap or rivet it to the existing aluminum plate. Plenty
strong enough and you won’t have to drill the mast to secure it or
run the wire.

I wanted to add a third folding mast step to my CF mast, so I got in touch with the tech service department of a major manufacturer of carbon fiber masts. The reply:
It is important that the area you are putting the mast step is not already crowded with other attachments. A general rule of thumb is to be 5 x the diameter of the screw away from anything else. So if it is a clear area on the mast it should be fine to drill holes for a step. Assuming the screw holes are not over sized.
Just to be on the safe side, I only used three of the five mounting holes on the step and also used 5200. I used pop rivets instead of screws since they spread the load better. If you look at the number of holes that are already on your mast, it is clear that a few new holes won’t bring it down onto our heads. But I do think that the extra respect we all show towards our masts is probably why we have so few problems.
If I were attaching something without mechanical fasteners, I’d use thickened epoxy since the masts are already partly epoxy.

when I went to the “Yard Sale,” one of the yard workers said that
screwing things into the mast was not as big a deal as people make
it out to be, but he offered these tips:
Don’t use self-tapping screws. drill the holes, tap them, and
then screw in.
seal the hole with epoxy (preferably two-part) when doing the
final mount for the screws. This helps maintain the mast integrity.
They seemed pretty confident that this was a superior method to pop-
rivets, though that’s how my track is attached.
I used this method to mount a combination steaming/deck light, and
I’m quite happy with the results.

I spoke with Eric Sponberg,who was an engineer of some of the earlier cf masts
at freedom, and if I understood him correctly ,the more rouned the hole, the
less of a problem it can cause in a cf structure.

My Hoyt32 has a Combination Steaming/foredeck light that is fastened to the mast with 1/8th pop rivets. the wiring is led thru a very small hole as the wires look to be 16 guage or possibly smaller. the light unit is a standard model made to be screw mounted on the leading edge of any size mast with flaps on each side of the light. I think it is probably an older model Aqua Signal. Anyway, I’ve had the opportunity to check all the holes in my mast and have found absolutely NO indication of fracture, cracking, or any other potentially bad scenario. By the way, this mast was new in '98 and has the track fastened with 1/8th or possibly 3/32(?).rivets. Again, no indication of any problems with the use of the rivets.
Personally I would be more than slightly hesitant in the use machine screws/bolts, or anything that required tapping threads into the carbon fiber. I think a much better solution is the use of rivets, pop and otherwise. I’ve had considerable experience using a type of heavy duty pop rivet sometimes called a monobolt. You can get them in aluminum, steel, and stainless steel. if you have need for a really nice looking rivet/monobolt, contact Prevost Car in Quebec (the hi-end bus/motor coach builder). They have very nice polished stainless units of varying size and length. And believe me, they are STRONG!!

My understanding is rivets should be used and not screws . Of course no holes is
better. My tracks put in by freedom are riveted.

Yeah, I was wondering if anyone was gonna jump on that. Truth is, it’s kinda shrouded in mystery. The best scenario I have been able to come up with is that one of the previous owners who raced alot decided to try a spinnaker flown from the masthead without the use of any kind of a backstay arrangement. I happened to find his revised rating for the boat due to the oversized spinnaker in with the boat’s papers. I’ve tried to contact the previous owners that would know, but nobody’s talking. Bottom line tho, I come out the winner with a nice new (fairly) TPI stick, in excellent condition that nobody has screwed-up thru ignorance.
As they say, “that’s my story and I’m stickin’ to it”. One thing tho, someone who knows the true tale may see this on the board and clear up the mystery, who knows.
