Small job-shop contract with (actual) money

But not much.
I have an ongoing small job-shop project, if you wish to quote on it. My
prior vendor just "vanished" (really). Price does matter.
We sell three steel "guns" for stage work. They are loaded with various
types of flash powder for noise or spark effects. They are:
1) Cannon Simulator Pot - a 1" i.d. x 1.5" o.d. x 2"h seamless tube
continuously welded perpendicular to a 4" x 4" x 3/8" plate. The tube has a
(roughly) 9/64" hole drilled near the base - just above the weldment - for a
"touch hole" (like a cannon).
2) Sparkle Pot - a 3" i.d. x 3.5" o.d. x 2"h seamless tube
continuously welded perpendicular to a 4" x 4" x 3/8" plate.
3) Three-way concussion gun - three 2" o.d. by 4" long solid rods
drilled with a 1" bore 3.4" deep. Three are spaced out and continuously
welded perpendicular to one 10" x 4" x 3/8" plate. This item takes strong
explosive force, so must be of an alloy that won't fatigue crack (1000s of
shots, but not many tens of 1000s). Dunno if regular merchant stock ("mild
steel") would do, or not.
Actual dimensions on the tubing in items 1 and 2 aren't too critical. They
should be close, with the object to have nominal 1/4" walls on the tubing.
Item 1 can hold a tube item with a slightly under-sized nominal 1" o.d., so
it must have a 1" bore.
Seamed tubing of any variety is NOT acceptable for items 1 and 2.
Item 3 must have at least 0.5" unmolested virgin metal at the breech end of
the barrel, and the hole should be finished out with some slight radius at
the bottom shoulders of the bore to reduce stress risers.
Each base has two 5/16" mounting holes, on diagonal corners.
Each item is given a cursory cleaning and de-burring for handling safety (no
weld blending, just knocking off spatter, etc), then is painted satin black.
We sell 30-40 of each per year, and would prefer to take about half that
amount every six months, both to keep our lump outlay (and yours) to a
minimum.
We have inexpensive shipping available through deep discounts with a
national freight carrier.
If you want to do this, contact me off-line for details. We don't have
drawings -- will have to do them over again, because our original vendor
both did the drawings, and vanished with them.
I'd do it in my shop, but I'm rubbing up against 90 hours per week right
now, and can't use the extra "wake up time".
Thanks,
LLoyd
