  1. Hmm... Well, the electronics in the plan are fairly inexpensive. I might by them and see if I can succeed in building my own before I buy a system, both for money reasons and just because I enjoy messing around with stuff like this (even though I have very little experience).

    I did come up with one more question though. In order to add a volume control to the system would I just put the pot before the signal reaches the piezo buffer? and also what size pot would be suitable?

  2. So I'm actually going to try and start this project soon, but I decided that before I go and build the instrument I wanted to get all the electronics sorted out and working. So I have a couple uneducated questions about the Helmke circuit. The parts list he's provided is no longer up to date so I can't find the parts he suggested, I went through and found parts that I thought were similar, but I'm an electronic noob and don't know if the are actually parts that work. So my main question is whether you could checkout a couple of parts and make sure the are satisfactory.

    He said on his page that, "The input and output capacitors (0.033uF and 0.1uF) should be something good for audio"

    I found:

    "The 4.7uF capacitor can be tantalum or electrolytic, doesn't have to be anything fancy"

    http://mouser.com/Search/ProductDetail.asp...647-UVZ1E4R7MDD

    "The 20pF capacitor is now 1pF - really just a tiny little value to shunt RF to ground. "

    Those are the parts I was unsure of, if anyone has the time to check and see if they would work, or suggest better ones that would be really great.

    Also has anyone tried the solder wire from Guitar Fetish? I'm going to be getting some other parts from the project from there and was thinking about getting that wire, but I was going to pick up a 25 watt iron from Mouser for cheap. Last question. Should I just pick up some insulated wire from radio shack or get my wire elsewhere?

    Thanks again for all your help. I wouldn't even be this far without all the information on this forum.

  3. I play the viola (but not very well, I've also never built one so I don't know a lot about there construction). Not sure why there is a string tied around the sound post but I agree with JohnRossitter see if there are any violin luthiers, so that you can ask them some questions. Hope it turns out well.

  4. Do you only us a rasp when shaping your necks? (just gathering different peoples opinions/ways of doing things for my build)

    What I do is use rasps at the headstock end and the heel end, when those parts are at the required shape you join the two pieces with a spokeshave/drawknife/etc.

    Ok, that's probably what I'm going to do.

  5. If you're going to use any sort of catalyzing product, you have 2 choices:

    1. Prepare to clean the living crap out of your guns constantly, or sooner or later, you will just dispose of your gun and buy a new one.

    2. Prepare to clean your gun decently, and also prepare to dispose of the gun sooner or later.

    Moral of the story: if you're using a catalyzing finish, prepare to dispose of your gun sooner or later, so don't go buying a super-fancy or super-nice gun, it's not worth it when an average/disposable gun will do just as well and wqon't break your heart when it comes time to can it and buy another one.

    If you want a cheap one (I've never tried it so I can't give you any personal reviews) stewmac has one that is fairly inexpensive.
