Bridge lift fix?

Strung up my first last night and I'm pleased to say it sounds better than my HD-28! However, I noticed tonight that the bass side of the bridge is lifting slightly and immediately took tension off. I was sure I used enough glue. What's the best way to fix this? Hopefully not removing the bridge? Thanks.

what glue?
You may be able to work some glue under the gap and reclamp

I suspect that the way to really fix it is to take the bridge off, remove all the old glue down to clean bare wood, and re-glue. If you used hot hide glue, meticulous cleaning is not necessary as hhg will stick to itself.

I used titebond and had plenty of squeeze out. It is only lifting a little on the side and by less than a sheet of paper. Is it possible a little skin oil kept that side from holding?

I wouldn't think that would be enough to keep it from bonding. What is the bridge made of? If it's an oily wood, did you clean it first?

The luthier I took "lessons" from recommends using the lethal variety of paint stripper to clean wood before gluing. At minimum, it ought to be well wiped down with a good solvent.

Often this happens when the bridge is sitting on a ledge of finish. It prevents a wood to wood bond. If that is the case the bridge needs to be removed.

I'm not 100% sure at the moment what the bridge is made of, it's whatever is shipping with the Martin kits. I really need to get into the habit of cleaning everything first. I try my best to wear gloves after I do clean the wood, but sometimes get too excited and forget...like when being close to finished!!!

I used tru oil for the finish, and spent a lot of time cleaning up the footprint, so I don't think it's sitting on a ledge of finish. I will attempt to push some extra glue under the side using a feeler gauge, and re-clamp it for 24 hours. If that doesn't work, I'll study bridge removal (which I need to learn anyway). I'll keep you all posted, and hopefully soon, I'll get some pics up. It really is a beautiful guitar and sounds amazing!

the bridge is most likely richlight the amount of lift may not be a big deal Just keep an eye on it for a few days and see if it changes

I would try watching it like John says, or wicking some glue in, clamp, restring and keep an eye on it. A substantial part of the load is borne by the bridge plate, isn't it? Richlite is what comes with kits from Martin. It looks good, glues good, and sounds good.

Overall, a .1mm feeler gauge just went in about an inch or so from the side so I think the problem is worse than I thought. I saw a bridge removal tool on stewmac but they wanted $40 and I can easily make it in an hour or less for about $2, so I will do that!

I'm going to look at this from a positive perspective and figure I'm about to learn a lot about fixing guitars! Hopefully I don't need a neck reset on my HD-28. If so, might have to learn how to steam it off soon! lol
