Would someone be kind enough to point me to the right kind (size, material, etc.) of hammer to deal with bridges that are starting to pull over towards the neck side? This happens often enough, and several of my students rent their basses from me - it would be a good thing to be able to do myself.

While I will certainly appreciate suggestions like, "use a regular hammer and a piece of wood", I'd like a link(s) to buy what I need online. I like to have the right tool for the job, and I'm always hesitant to take on something like this myself. Is there a Stew-Mac equivalent for bass? That's where I've bought guitar-related tools, and I feel handier with guitars, probably because I've been playing them a lot longer than I've been playing upright, and also because they're a lot less expensive.

Thanks in advance for advice, links, etc., and if anyone has a spare hammer of the right sort they'd like to sell me, I'm perfectly happy with a used tool.

@Tom Lane, I have always found I put too much or too little pressure on the bridge when I do this by hand - no idea if it's what sort of strings I tend play versus what you play, or if you've simply got the better touch.

Hammer? I just press the bridge gently with my thumb. Have I been doing it wrong all these years?
NO. (I would never use a hammer. Even a Nerf Hammer.)
IMO.
I just take some of the tension off of the top by detuning the strings a bit, then, (gently) "coax" the bridge in the desired direction, (using BOTH "thumbs/hands"), then slowly retune. During retuning, I can check and re-coax, if needed.

But that's me.
Thanks.

I think I was "shown" once by a luthier but now I can't remember which one. (S)He told me that I didn't need to detune (and I don't because it usually happens when I'm installing new strings so...) and that I should hold the bridge feet with one hand while gently using my thumb until the feet fit flat against the top. Steady and slow was their instruction. I've also been told to use the edge of a paperback book but the first luthier did not agree because he felt that any kind of tapping was too uncontrollable and I might whack the bridge too far and knock it over. Steady pressure seems to work well for me. I've always used synthetic strings except for the occasional Spiro or Heliocore, but my method seemed to work fine on those too.

I was also told/shown by several luthiers to tap the bridge back into place using a paperback book between the D and A strings, no detuning necessary. I've done this for ages now with no problems. I often end up using a Vonnegut novel, but that may just be coincidence.
Alright, now we're getting somewhere - thanks, Chris.

I don't always smack my bridge with a book, but when I do, I use this...
