How to re-bed hand rails?

Okay J/30 newbie question here. I’ve got rain water dripping down the interior ceiling handrails. Do the exterior rails thru-bolt into the interior rails? How do these things come off? It would be awesome if I didn’t have to remove the plugs on the interior rail because finding Ash plugs doesn’t seem like an easy task and I really don’t want to have to re varnish. Can it be done from just the top? Teak plugs are easy to find, and I think the exterior is just finished in teak oil.

Kellen - they are through bolted with bungs covering top & bottom. I don't think you would be able to remove one side as the opposite end needs to be held to unscrew the nut.

Take the plugs out of the top teak rails, under the plug there is a nut and washer to back off (I had no problem doing this).. Pull top rails off as well as inside rails. Drill oversize holes and fill with epoxy. Re-drill, holes for the screws that are coming out of inside rails - take your time to make sure you center the new holes in the epoxy. Re-bed top and inside

Thanks for detailed info. Hopefully Russ is right and I don't have to remove the plugs on the interior rails.

Mine were frozen when I had to remove the top rail so I had to remove upper and lower.

If it turns out you have to pull the plugs out of the inside rails, I have some ash laying around as well as plug cutters. Just let me know the size of the plugs and how many
