I have been unable to find any posts/threads concerning this issue. I need to remove the traveller in order to re-bed the bolts to eliminate a leak that I suspect is coming from one or more of the bolts. The issue is that I cannot remove 4 of the bolts. I am starting to strip the Philips head. I think the only way to proceed is to drill out the bolt heads, remove the traveller, soak the bolts with penetrating oil and remove the remaining bolt sections with vice grips. Any comments or other suggestions would be much appreciated.

I just removed my traveler. A #4 Phillips on a socket is what you need. [url]http://www.sears.com/craftsman-no-4-phillips-bit-socket/p-00944373000P?s.... Try this possibly chucked unto into an hand impact wrench [url]http://www.zoro.com/g/00155822/k-G3395646?utm_source=google_shopping&utm...
Failing this, I'd try and EZ-out next. With the bolts removed, you can slip a filet knife between the bottom of the track and the base to cut the bead of 5200. As a last resort, drill out the heads, lift the track, and vice-grip the shanks. Cut as much of the 5200 as you can using the filet knife, knowing that if the bolts are still in place you'll be working against some 5200.
Makes sure you tape the sheaves into place because the through bolts hold them in. Potentially hundreds of 3/16" black plastic ball bearings rolling down your deck is not what you want.
On my boat, the six inboard bolts thread into a plate that is embedded into the traveler base. The two outer bolts are through-bolted. I'm rebedding mine today, so I'll take some pictures.

Thanks Nick. I succeeded in removing the 4 bolts today by drilling out the heads. Oddly, the 'frozen' part appears to have been some tough sealant (5200?) at the head of the and not at the nut. Once off, I was able to remove the remaining lengths of bolts quite easily. There was no 5200 bedding the traveller.....just some silicone that covered/sealed some but not all the holes! No wonder there was leaking. I used a counter-sink bit on all the holes and I plan on re-bedding with butyl tape. However, the challenge will be dealing with the groove in the underside of the traveller and ensuring the butyl tape compresses properly and seals properly around the bolts. I don't know if your traveller has the same profile but if yes, would appreciate how you plan on or achieve bedding/sealing.

The bottom of the sheave box and the traveler base is where the butyl tape will compress in the countersink and do the most good. My plan is to silicon most of the bolt and use butyl where the compression/spreading characteristics will make a gasket. Pictures later today....

Nick, silicon on the bolt will do little, if anything. You should follow Maine Sail's How To rebed deck hardware. You seal the underside of the bolt head with butyl, too. And an extra layer of butyl tape underneath the notch in the bottom of the bar would help, too.

Step 3 - Press the through bolts into deck hardware with some good pressure.
First though make sure the hardware is clean, Acetone works well, but if Silicone was previously used you'll really want abrasives as Acetone won't touch dry silicone contamination.
Gelcoat silicone contamination is a whole other subject for a whole other day. [B][COLOR="Blue"]Please avoid silicone except for certain tasks involving plastics that require its use.[/COLOR][/B]

Thanks Stu. As soon is the weather in New England improves, I'll tackle the bedding challenge. This is the only area of our boat that has slightly elevated moisture readings and I believe it represents one of the most challenging areas to bed properly. Six of the eight threaded fasteners are machine screws (meaning the head is turned to tighten) and the remaining two are bolts (meaning a nut is turned to tighten). I think butyl is like any other sealant when it comes to the head of a machine screw, i.e., the act of fastening twists out much of the sealant. But with a properly prepared hole and fastened bolt (countersunk hole and bolt head held absolutely still while the nut is turned) butyl for sure is the best choice as it compresses into a beveled o-ring.
Fair to note the traveler track does not sit directly on the traveler base. Each threaded fastener head is countersunk into the track, then passes through the track, then passes through a sheave box, then passes through a bit of the traveler base, and then engages either the nut plate or nuts. If you count 'um up, each threaded fastener gives water an ingress opportunity at five different places. That's 40 places total! The vast majority of water ingress is likely from the top and bottom of each sheave where the fasteners pass through and where butyl cannot be applied. I was originally thinking silicon here because of it's flow characteristics, but I'm rethinking this. My strategy is to butyl where the sheave box meets the countersinks I've made in the traveler base and just use silicon on the portion of the machine screws that extend down past the countersink as a last line of defense.

Any updates or thoughts on the best way to re-bed the traveler bar? I am considering using buytal tape but am concerned that by turning the bolts I will displace the butyal.
What has everyone else ended up using and were you happy with the results?
Thanks

In the Fall 2014 Issue of Mainsheet I did a write-up on rebedding of our traveler. Using a moisture meter every season since indicates no water ingress.
