Any tips for rigging an A Frame

Finally my replacement A Frame is ready, so im planning on rigging it this weekend, do you have any tips on rigging, I need to pull through the following cables;

AIS GPS Antanae cable
VHF Cable
Nav lights x 2
Steaming light

Im thinking of threading some good strong string through the various points on the A Frame, then putting some adhesive around the mounting holes, then threading the sring through the holes and mounting and loosely bolting down, then pull through the cables with the use of the string and final bolt down, then connecting cables in boat.

Does that sound reasonable or do you have a better method.

If you have and thin wire push that through first then pull the string through. Then tie string to wire tape that then a bit of washing up liquid over the tape to help it through.
Hope that makes sense.

if you can terminate direct to the nav light fittings rather than a joint that's the best way, then run directly back to the switches, less joints the better, but don't pull the wiring tight, leave some slack in the A frame, you never know if you'll need it in the future, talcum powder is good for lubrication to get things moving when pulling the cables through, and if you can use some corrugated hose when the cables exit the tube ends, just to protect them, if not a good layer of insulation tape

I'd also suggest leaving a pull line (string or wire) in place in case you decide to add something at a later date.

If you do find you need to get a string in, tie a small piece of cloth on the end, and use a shop vac to suck it through.

All good tips.

Some of my own:-

Put a thin line in each hole so every wire is pulled through by it's own line. Make every line long enough (like a normal lazy line) that you don't lose it if the cable gets detached from it.

Tie a knot in the line and tape the cable to it (stops the line slipping in the taped join).

Put the longest cables in first and (assuming it's all coming out of one hole into the hull) leave the line on the longest cable for use later on if you want to install other things on the A-frame.

Hi,

When I replaced my VHF antenna cable and put in a second antenna for the FM radio I had a devil of a job feeding the wires through the A frame. In the end I went to Screwfix and bought one of these

http://m.screwfix.com/pr-gallery.htm?id=75807#imggal1

It's a cable and flex draw tape and made all the difference. You can borrow mine if you like. Alternative is an old throttle cable inner, however I found that too stiff to get round the bends on my frame which has some right angles to get round.

Good luck.

Oscar: Your link brings up the Screwfix top page. I assume you're talking about a cable fish tape?
