Rather than screws and nuts, harps that come without nails come with "male and female" screws? Since I'm about to do my first big mod job on my Bb MB (unless I follow the DeFord Bailey route and throw it in a bucket of water), I'll look into the price of a drill, but I wouldn't know what those screws are called or where to buy them. Anyone care to list some basic hardware (hand drill or stand mount, e.g?) and maybe some links to suppliers? (I don't think I'm going to get as technical as to replace individual reeds yet - I'm just thinking of beeswax and drilling and filing off the corners and that's about it. That's probably enough for lesson 1). If it's a success, I've got 8 other MBs to mod, so a certain outlay will be worthwhile, I suppose.
(damn, I can't edit the thread title, how embarrassing!)

andrew - you can get most of what you need at www.harponline.de click the Union Jack at the top if your not comfortable reading German, click accessories and then screws on the side menu. Scroll down to cover-screws MS system. (In my youth as a skater we called them 'sex-bolts', but here they're just 'long nuts'!) Payment by PalPal makes the whole foreign currency thing easier. It's not the cheapest and the exchange rate is against us these days, but it's good having it all under one virtual roof.
Beeswax you can get from Hobbycraft.

Andrew I buy my bolts at boltdepot.com. It is in Mass.
It cost me $24 for a bag of 100 (2-56 x 7/16" stainless steel philips head machine screw bolts) and bag of 100 2-56 stainless steel nuts. Thats for the reed plates and comb. I bought 50 (4-40 x 1/2" stainless steel philips head machine screw bolts for the covers. And 50 (4-40 stainless steel nuts)
I still say nail it the way I said and will be perfectlly air tight!

I'm going to try this as well. Appreciate the measurements Chrome. I really like the marine band and would like to seal the comb and change to screws for easier access.

Have you watched the video from elk river harps?
Dave payne does it with the original nails and I have had great luck doing it the same way! I can tune my blow plate reeds without taking the harp apart! Just thought I'd mention it. Don't believe everything you hear. Bolts and screws will not make it more air tight, but you will be able to take it apart!

Andrew I thought I would just mention that I file the reedplates down to the wood at the mouthpiece. I stop when it just starts to hit the teeth. I also round the corners off quit a bit before taking it apart. After I take it apart I file a small 45 Degree angle on both side of each tooth. Go easy here you don't want to remove to much just enough to get rid of the edges!
I can't tell you what size drill to use because I have so many. I didn't think I would be telling someone else how to do this. If you know someone that has tools and knows how to use them. Have measure the bolt with calipers and get a drill bit that is the first size larger than your bolt. Drill into a piece of wood and test it. See if the bolt goes in easy. You shouldn't have to force it! I hope that helps. If you any problems feel free. I'm sure one of us can help!

I use 2-56 bolts but anything that fits what you're doing will work for you.

As hopefully one of the "and others," you can get this harp playing as tightly as anything by flatsanding that comb, doing the toothpick trick and driving the nails back in.
But screws, you can do a great job with those as well. I use 0-80 screws and nuts. I ream out the rivet pads of old reeds that I've changed out (and cut the reed part off) and make lock washers out of those. On the screw beside Hole NO. 2, the head goes on the draw side, nut on the blow. That's because the No. 2 is very close to the rivet pad of the No. 2 reed.
