Re: re-forming styrene rod
- I used to work with glass rods; you can heat the glass rod over a torch and
pull "stringer," long, very skinny rods.
If you try this with styrene, you might want to start with a thicker rod,
maybe 1/4" diameter. Heat the center of the rod, and test pull until it
starts to elongate, then pull evenly, moving the heat toward one end of the
original rod to keep a fresh supply of styrene molten. With practice, you
get a nice, even thickness. Not so sure about accurate diameter, though!
I want to create small pieces of cylindrical styrene rod about 1.5" long
and 0.2175" in diameter with a partial groove along one side and one end
tapered. I am currently hand sanding styrene rod with diameter = 0.25, but
I would like to automate the process for quicker production and

- CKA and group;
It sounds like your frustration is in not having the right diameter of rod. To that end, it sounds as if you need a draw plate such as seen here:
Note that the stated smallest diameter is conflicting - they say .12 mm or 3/32" - that would be 1.2mm. You may be able to find larger-sized ones from a jewelry and findings supply house (Google will help here). Failing that, for the size rod you want, a lathe will do nicely. Or a shop equipped with a lathe...
Hope this helps - a vac-former is not what you seek.
