    Rosenthal supply,Miami has a great assortment of all types of draw
    plates cheap to pricey. tubing though is easier than it sounds..
    lube a common gauge plate and you can pull sheet that is annealed
    through it to make tubing, or swage it on a block or a routed piece
    of hardwood to start it, then flow solder on the seam. polish and you
    are there!. have no fear!just try it. anneal some 22-24 g sheet
    silver, and if you want a quick experiment, take a piece of 1"x4" and
    drill a hole, if you have silver and demming bits drill a tapered
    hole, then lube it well with a stick of cocoa butter, beeswax, or med
    weight oil. (not light as it will be absorbed by the wood), then roll
    the annealed sheet around a broach or any mandrel that is about a
    size or two larger than the hole you have drilled,if you have draw
    tongs-great- if not cover your favorite gripping parallel type with
    some tape or stick on felt strips ond pull it through the "plate"
    until you have a solderable tube of a length and i. d. /o. diameter
    it is far easier than you may think, Most suppliers sell tubing in a
    variety of colours,karats, wall thicknesses so double check with the
    sales person that it is not misprinted. at present I think D. H. Fell
    has the thickest seamless available- could be wrong, but of the
    stacks of catalogues i have that comes to mind after trying to have
    some sent from Hoover and strong- which is only standard in wall
    thickness. there sre some tube settings though that come in fairly
    thick, though nowhere near what you can make yourself. and there has
    been a recent noose, uh, thread, about good tools vs. bad tools.
    drawplates were cited- if you are begining you don't need the
    sapphire lined precision tapered 600 dollar drawplate. the 25 dollar
    model works equally well if you anneal and lube conscientiously! R.
