need heating element
 

Have an old theater popcorn popper and they no longer supply parts for
my model. I need the coil type with 3/8 " od and 3 foot long. about
2800 watts. The old one was 220 volts but I prefer 115 volts. Dryers
are too hot and 220. Any ideas would be appreciated. Dale

Check with an electrical parts outlet place, motor repair shop, etc. and ask
for an appropriate length of "nichrome" wire. They should be able to help
you determine the correct gauge and length for 2800 watts. You can coil the
wire over the insulators in the same form as original.

If you are referring to sheathed elements like those in electric ovens
then they are available from electrical/electronic suppliers in various
lengths and wattages. For instance www.rswww.com search for "Straight
Element Immersion Heaters". These can then be bent as per the original

Hi Dale:

It may be obvious but 2800 watts at 115 volts means about 25 amps; a 30
amp circuit and 10 gauge wire (or is it 8 gauge? Go with 8 ga for a
margin of safety) will be necessary.

Just a thought.

By "coil type" he may have meant that the nichrome wire was in the form
of a close wound coil spring (like the old "hotplates" used to have.)
before getting stretched slightly when fitted into or around the ceramic
insulator(s).

If that's the case then he'll need to use some sort of spring winding
technique.

Since the OP said he'd like to change from 220 volts to 115 volts, if he
keeps the "spring OD" the same, and the number of turns the same, he'll
have to use a wire diameter about 1.4 times the diameter of the present
wire to get about the same wattage from the same number of turns at the
lower voltage. If that doesn't leave enough room between the turns when
fitted into/onto the insulator(s) he'll have to go to a slightly thinner
wire with a few less turns.

That could get interesting...But it wouldn't take rocket science to
calculate what's needed for a given "spring OD".

Good to know.

To the OP, mebbe a dishwasher element (perhaps 2) would work, easy to find
at scrap yards, more often 120V.

This is easy to make yourself, so don't think you have to hunt around for a
ready-made replacement.

Mic the resistance wire diameter. Estimate the length, look up ohms/foot
for the wire diameter, confirm estimated resistance close to measurement
with an ohmmeter. Buy a spool of that size resistance wire from
http://www.mscdirect.com/ and wind your own coil around a dowel. Winding
coils in the typical wire gages is not difficult.
