Hi folks
I believe I've found what may be a good replacement heater for the Jensen #45 candlestick steam engine.
here is a brass boiler Jensen #45 steam engine that I have completely restored. it came to me needing restored & had a non-functioning heater, I finally decided to see if I could come up with a modern replacement & I was fortunate to find something that worked quite well, here is the title to the little stove on E-bay right now "Portable 110V 500W Electric Mini Stove Hot Plate Multifunction Home Heater DIY" it was US $21.48 & was the least expensive I could find of this type. with a little modification this heater worked quite well ,the advertised watt was 500W, but my Digital Power Saving Energy Monitor Watt Amp Volt KWh Meter Electricity Analyzer say its right at 600W , you will need a voltage reducer /variac to be able to run your steam engine at a realistic speed. this #45 has a brass , dent free boiler & all the part were in good shape before I started the restoration. I use powdered (fine) graphite in the axle tube to see if that was slicker & gauld free...time will tell. it runs nice & slow @ 40V/75W & at that speed I expect it will run well over an hour.
If you have the time , please follow along ...
here is the new donor heating single burner electric stove , its called a YQ-105, they're probably all the same, just find the cheapest one you can.
this is what your after
I trimmed about 1/4" off of it to fit , in hindsight i would only trim off about 1/8" so i could drill right into the cast iron lip & tap it 6/32" to accept the 3 bolts that hold the boiler onto the heater base.
this step could be removed in the future as the 3 afore mentioned bolts hold it firmly in place from the topside.
While I was at it, the (2) 5/16-24tpi ports in the top of the boiler were rather worn & 2 new brass bushings were made for a lifetime of robust use.
the heater now set in place
insulated in
A double layer for inside the base (this worked better than i thought it might)
nearly finished.
