Another Elektro Resurrected
By: Junkologist Date: September 11, 2022, 8:55 pm
---------------------------------------------------------
Snagged this Elektro engine on eBay last week and discovered it
had a burned out heater when I got it.
I made a new heater for it today and now it runs pretty good,
although the crankshaft bearing is extremely worn and make the
flywheel appear wobbly along with creating some noise. Still a
great piece.

that is really great - it would be wonderful if you made a
dedicated post on just making the heater with list of supplies
(part numbers / source sites) - perhaps even with a video.
Looking at your last photo it looks like a simple-ish task.

I was bidding on this engine - it is an early one. You
are very lucky to get an engine that runs at all - it is
not a very good design. My experiences with Elektro's
taught me that. The heater is the easiest thing to work
with. The last one I bought had a working heater but the
engine is a non-runner. I've replaced the engine with one
I had on the side and am now running it in with an Erector
set motor w/gearbox. I'm such a fool for Elektros.
Congratulations,
Wayne

Nice repair Mike! I see you even marked the new one to get the
exact same wraps as the original

Congrats, Mike! That one is in really nice condition, aside from
the worn bearing.
Do you remember what ohms/ft. nichrome wire you used for the new
heater?

Yes, please Mike - the details on the Nichrome Flat Heater Wire
would be great - would love to have the supplier/part number :-)

Did some figuring on this...
I have an old heater from a B30. The heating wire itself is
good, but the aluminum terminals have rotted off. The electrical
info, from the nameplate reads:
110 volts, 375 watts.
If I = P/V, then the current = 375/110 = 3.41A
If R = V/I, then the resistance = 32.3 ohms (The ACTUAL
resistance measures 28.5 ohms, for whatever that's worth)
The number of turns is approx. 34, at 2.5"/turn, which gives a
heater ribbon length of 85"
85" = 7.08 ft., 32.3 ohms would require a wire resistance of
approx. 4.6 ohms/ft.
I measure the wire ribbon size at .004 thick X .031" wide.
This source has wire available in 5.15 ohms/ft, .0035" thick,
and 1/32" wide, which would work:
(HTM) https://jacobs-online.biz/nichrome_ribbon_wire.htm
It's the first size listed, with various lengths available.

Thanks, Wayne! I believe these early engines with the cast iron
base are much better in quality than the later stamped steel
base engines. The cylinder is cast iron on these early engines
and this one is in decent shape even though it is apparent that
it didn’t get the lubrication attention it should’ve as
indicated by the excessively worn main bearing.
I don’t think you were bidding on this particular one since it
was a BIN or best offer listing.
