Restoration of a mid 1960's Jensen 50 (PART B)
By: IndianaRog Date: March 9, 2023, 8:43 am
---------------------------------------------------------
As I began restoring this unit, I wished it had been one with an
original water reservoir cup on a tripod stand as this makes it
easy to keep up with the boiler's water needs. Solution was to
make such a cup/stand to same dimensions as those Jensen used.
Only difference being that Jensen used 1/2 of a 25 size boiler
while I opted for a stainless child's cup found on eBay.
Remove the handle and add a drain...Bob's your uncle! Legs were
made of polished aluminum hand bent to proper shape.

[attach=2]
I found a separate SS creamer lid that fit the cup perfectly...I
use it to keep dirt/bugs etc. from falling in the cup when not
running...not something found on original Jensen 50's, but
practical and detachable.
[attach=5]
During refinishing, I opted to leave the 375 watt blanket heater
in place...though NOT connected. Having installed two 555 watt
new immersion heaters into the boiler, I decided that was
enough...though a future owner may want the blanket heater
operational, so I left it.
[attach=6]
I chose to run all new wiring to the pair of 555 watt immersion
heaters. Original setup was two x 300 watt immersion heaters
plus the 375 watt blanket heater for a total of 975 watts. As
restored I have given it a little more. Two x 555 watt
immersion heaters totaling 1110 watts...close enough!
[attach=7]
The following photo shows the new immersion heaters in the newly
re-nickeled boiler. Also visible is a discrete green ground
wire, something I always do on a complete
restoration...electricity/water and metal just seem safer with a
proper ground wire!
One bit of SPS handiwork is visible in this photo...high temp
soldering...something I am NOT good at.
One of the bushings holding one heater rod in place was loose
and would have leaked like a sieve. Bruce high temp soldered
BOTH heater bushings for good measure, THEN the boiler was
re-nickeled, plating over the solder work which disappears once
the chimney stub is in place.
[attach=8]
Rear view of engine layout showing the water reservoir and twin
plugs for the immersion heaters. Though I prefer to control
voltage and resulting PSI using a Variac, Jensen's original
approach to reducing voltage/PSI was to unplug one of the
heaters where it plugs into a surface mounted multi outlet
fixture. That is still an option if one doesn't have a Variac.
An easily removed "blanking plug" is visible in the rear of the
chimney stub. If a future owner wants to reconnect the blanket
heater, short cord/plug would go here and plug into center of
the surface outlet.
[attach=10]
A vintage looking three prong plug completes the electrical
work.
[attach=9]
That's it for today, check back tomorrow for PART C...featuring
a number of SPS machined parts that saved this restoration.
cheers,
Rog

Wonderful photos Rog!
What material have you used for the legs that hold the feedwater
"cup", that seem to bend to shape so well? My guess is aluminum,
but I'm expecting to be told I'm wrong about that?!?!

I used 3/32" thick aluminum sheeting, cut into strips with a
hacksaw and bent to shape with a pair of vice grips...polished
the finished pieces with SimiChrome to get a stainless "look".
Took a few tries, but probably only scrapped two pieces in the
process! Center cylinder support was part of a grease gun I no
longer used...fit the part perfectly. Love repurposing such
bits !!

Well Done!!!
Thanks for the reply and info.
Don't happen to have eBay links to the cup and lid by any
chance?
And please don't tell me that the aluminum legs info was in the
first few lines of your original post of this thread, but I
certainly see it there now. How in the heck did I miss that the
first time around?!?!

Nice build on that water tower Rog! Have you thought about
adding a Jensen tube style sight glass to it? I use an
Ozsteamdemon water tower and when it’s full, the weight of the
water must make it easier to pump because I gain a porthole
sight glass of water over a half an hour or so and if I let the
tower get less than half full I notice my boiler water level
drops, but very slowly. At first glance, I thought your grease
gun coupling was a 50 safety valve body.

Stoker...I don't still have the eBay link on the cup...but there
are lots of them listed on eBay...just search for "stainless cup
210 ml". The one I bought of that volume was 7 cm wide and 8 cm
tall...same as half a Jensen 25 boiler! Of course 100% of them
come from China if buying new. As for the lid, it came off an
old creamer I had in the kitchen cupboard...had not used it in
years, so sacrificed the lid to the cause. I drilled a hole in
the center of the cup bottom and threaded in a 1/8" x 1/2" piece
of threaded brass...PM research I think. A dab of JB Weld
inside and out and it's water tight! The handle came off easily
with a bit of careful Dremel work.
My lips are sealed, I wasn't going to point out the legs were of
aluminum as noted in the first few lines ;D

Nick, no need for a sight glass on the water cup, as the pump
drains it in just 2-3 minutes, and I have to keep an eye on the
water level continuously or it goes dry very quickly.
Now that I look at it, my grease coupling bit at center of the
tripod DOES look like part of Jensen 50 safety valve, but trust
me, a heck of a lot less costly!

Stellar work, I still can't believe how closely you made the
water supply stand like the original #50 water supply, that hold
down for the cord is still top-quality hardware in my book. it's
hard to believe that Jensen would put a little ol' 375-watt
heater under this monster boiler. your work looks better than
factory.

Daniel, I believe this was the source for my water reservoir
cup...measurements are correct.
