Re: Some "Dynomite" Heads!
Well I just couldn't leave it alone. Found this glass burette kit complete with stand and teflon stopcock for $60 shipped and just had to have it. It has a 50cc capacity with .1cc markings which greatly increases the accuracy of my measurements. I remeasured using the burette and was pleasantly surprised by how accurate my previous measurements were using the syringe method - all chambers were within about .25cc of my prior measurements. As it stands now I have 1 chamber at 42.5cc, 4 at 42.4cc, 1 at 42.3cc, 1 at 42cc and 1 at 41.8cc. I'm happy with the 5 chambers that are within a .1cc so I just have 3 that require some minor material removal. I am still using water at this time, if I can verify that my set-up is alcohol compatible then I will probably give that a try next since it's supposed to be a better measuring liquid. One thing I learned right away is that cleanliness is critical to using a burette, it doesn't take much debris to create a clog and it's a real bitch to get it out.
P.S. This anal retentive madness is all your fault Cliff since you won't be picking up your stuff for a little while yet
