Thanks guys...

Unfortunately, no... Nope But there was plenty of cussin' I can guarantee it! Curse

I get so involved in the process that ultimately forget to take any pictures until I'm almost finished what I'm doing. The spout was made using the method suggested in the RMC April 2011 issue. The process was pretty straight forward. Take three sizes of brass tubing, (I'll double check the three sizes but they fit together really well) telescope them so you get about 9 1/2 scale feet total length all together and then solder them into one piece. Place them in a drill chuck and file down the three tubes into a nice taper... I'll admit, this takes awhile. Once done, notch the end with two triangle shapes. (Do not cut all the way through!!!) Once cut bend the tube end to form the spout and solder the cuts together. If I had not been so over zealous with my solder, I could have poured water through the spout before assembling everything together, but plugged the hole. Misngth Some filing and sanding to shape is required to clean things up a bit. The attachment points for the chain are made out of some .010 brass shim stock and cut and filed to shape and some bent brass rings.

The pulleys were made in much the same manner, using two small brass tube sizes telescoped and soldered together. For the pulleys, I left a bit of the smaller size sticking out so that solder would not accidentally filled in the hole. Again I used more shim stock to make the body for the pulleys, drilled holes for the pulleys and soldered a piece of .015 music wire into the axle area. The pulleys don't move but they look good. The pulleys ended up being about a scale 6 inches wide which was pretty damn hard to hold on to no matter what I used. My finger nails ended up working the best. I dropped them on more then one occasion and thought for sure I was going to have to remake them. Then I smartened up and placed a foil roasting pan underneath my hands. Not only does it catch the part, it makes a nice tin sound when the little part hits it.

The counter weights I was fortunate enough to have some brass tubing that had a small diameter hole that nicely accommodated some .015 music wire. To attach them to the chain, I notched the tubing and soldered a a brass eyelet into the notch. Like I said I used some fine bronze wire to tie the chains to the eyelets and secure them with s small amount of solder.

Edit: The brass tube sizes are; 3/16, 5/32, & 1/8 for the spout and 3/32 & 1/16 for the pulleys. Double checked the size of the brass shim stock and it is .010. Post edited to correct that size.
