*Fiberglass sleeve used - HTG fiberglass, does not fray like standard high temperature sleeving (1000F) and is rated for . See [http://www.hitexinsulation.com/products/HTG-Fiberglass-Sleeve.htm]. Note that the resin can burn out at the 650C (1200F) workign temp. Sleeve has [[VW-1]] flame resistance. Made of fiberglass, it does not burn out, but may fuse and lose fiber structure.
*Inner core: 5' long wraparound of 2mm tight braid fiberglass sleeve - 600C - [https://www.aliexpress.com/item/32862062385.html?spm=a2g0s.9042311.0.0.27424c4dnHgKvS]. Started with 5', wrap was more like 4' long.
*This is packed into 4' of 6 mm tight braid fiberglass sleeve.
*Fence wire is used to couple 200C wire to nichrome, in order not to burn out 200C wire. Nichrome is wrapped around the fence wire 5-10 turns
*Copper wire is soldered to the fence wire.
*10" end piece of 6 mm tight braid sleeve covers the 200C wire, fence wire, and ends of nichrome.
*2 strands of nichrome heater element are made, each 14' long, each about 600W.
*Ends, covered by 6 mm tight braid sleeve - stick out the finished bed. Third wire set is the thermistor, which is wrapped with 2 mm tight braid so it doesn't melt out.

*20 feet of 20 ga wire appears to be most convenient - 1 piece, max at 1200F. Current 500W heater is 1200F max, and works well.

-Back to working some on PVC 12" - was there enough torque to lift that bed with 2 Z steppers? I don't seem to have enough with properly tightened axis.

Cut List

Using 3D Printer Workbench 2020:

  1. [2] 22” - X
  2. [4] 21” - Y
  3. [9] 17” Z, bed, spool holder

Heater Element Wrapping Procedure

  1. Cut 14' of ga 24 nichrome
  2. Cut 5' of tight 2 mm fiberglass sleeve
  3. start the wrap of nichrome on one end of sleeve
  4. Attach other end of sleeve to a free-spinning rotor
  5. Once enough to go inside a cordless drill chuck - grab the nichrome wrap and turn on the drill in reverse to start wrapping. Tension the sleeve against the rotor
  6. Wrap away! A person should be able to wrap 4 feet long just by holding a cordless drill

Questions

-Back to working some on PVC 12" - was there enough torque to lift that bed with 2 Z steppers? I don't seem to have enough with properly tightened axis.
