Hi,
I recently got a Hohner crossover and have found that a large amount on moisture builds up between the top coverplate and the top of the blow reedplate. It seems to be getting in between that groove on the reedplate that the coverplate sits in. This happened only after playing for about 10 mins and I had to take it apart to remove what resembled a 3cm bead of silicone running along the inside. I thought the screws may have been loose and have now burred three of the soft brass screws!
Has anyone else had this problem? Also does anyone know if there is a suitable steel screw I could use to replace the brass ones?
Any help would be appreciated!
Thanks

TQJake, I'm not sure on the screw size. 0-80's will fit a tapped hole on a regular Marine Band (good for replacing the nails on the basic model). If you are going to put nuts on them you might want to go one size longer. I'm not sure what that would be but you could find it on a hardware site. I actually found the screws I needed to convert my basic MB to a DIY deluxe at a local model train shop. They were the only place that seemed to have the right sized screws.
As for over tightening, don't do it! Aside from stripping the screws and possibly the plates you can warp things if you tighten too much. You just want it tight enough so it doesn't rattle or unscrew from normal play.
Moisture usually isn't something you need to take your harp apart for, particularly on a fully sealed model like the Crossover (or plastic combs, either). Just take your harp and whack it against your jeans a few times. I don't know how long you've been playing but lots of people go through a slobbering phase early on in playing (I know I did). Eventually you outgrow it and you need to shake your harp out less often. I'm not sure about the silicone bead. I haven't played a Crossover myself. The only thing I've had to pull out of my harp is gross looking layers of dead skin and hardened gunk! (There actually is a good argument for leaving it in place, it tends to form most where air is leaking out, so it actually can seal those gaps and make the harp play better, although you want to keep it cleared off of the cover and from right around the holes- when it dries it will chew your lip up.)
I'm sure one of the customizers will stop into the thread and answer any other questions you have. Welcome to the forum. :)

Does your Crossover have the new or the old cover plates?
The first few generations of Crossovers had covers that were stamped like the 1896 MB. I find these to be a little leaky and rough around the edges. The new plates make a much better seal with the reed plates, and are smooth on corners.
I see alot of these screws stripped out. Most of the time, it seems that people are over tightening them. Also make sure you're using a POZIDRIV screwdriver and not PHILLIPS. The slight variation in screw pattern will cause the teeth to slip and strip it out everytime. If you need replacement screws, Hohner sells them for ยข75 ea.

Thanks for all your replies.
Adam, I have the new cover plates on the crossover. I have been playing for about three years. I also have a low f manji and they are pretty much the same construction and it doesn't have the amount of buildup and I use the manji for mostly tounge blocking chugging style playing. Nate, No amount of banging would have got out all the goo. It looked like I had spat down the back of it and would have had to bang the back of it dragging spit over the reeds. It wasn't gonna come back out they the way it got in. Ahh well, I'll just try to be more conscious of it and not play to much tounge blocking on it.
Thanks guys
