Title: Re: My first rivetted boiler with a four bolt engine from Jensen

Thanks everyone for the kind words and solutions. I cleaned the engine aggregate in the sink full
of warm soapy water and a soft toothbrush. Spinning the flywheel sure pumps the water through it.
Yes Wayne, I did run it on air to blow it out and it took right off.

You might wanna try using some acetone on that old glue acetone attacks most of that kind of stuff!!!

Congratulations Tommy!

With a little TLC, this one will shine again.

Good catch Tommy, you sure got an early one. Good luck on the refurbishment.

Congrats on your new four screw! You did well on that one. If I didn’t already have a few in my stable, I would have been bidding myself.
That stuff on the safety valve almost looks like glue to me, like that stuff called “Seal All”. It might just crack apart if you try to remove the safely valve. That nickel should polish up nice and you’ll have a very nice piece. Can’t wait to see it all spiffy!

Welcome to the club.  It will look great and be a good looking
runner when you are done.  It is good news about the heating
element - fingers crossed.  Mine took a bit of work too and is
a keeper.

  I took a look on the web for how to dissolve epoxy and a whole
bunch of not-to-tricky methods were displayed.  I wouldn't be
surprised if the epoxy could be pried, carefully and avoiding
any marks, away from the boiler, hopefully allowing you to
unscrew the S/V.  Have you tested the engine on compressed air? 

God Luck,
Wayne

That right there is a truly ICONIC Jensen and well worth any effort needed to bring it back on-line!

Nice Score Tommy!!!

Heat often works well on standard epoxy (not JB Weld) but that looks like it is just about ready to pop right off cold with just a twist of the SV.

I won this off of eBay a couple of weeks back. I always say if you learn at least one thing a day,
then you're going in the right direction. When I removed the engine base from wood plinth, the screw
holding the steam line to the boiler was just a screw. I thought I might been have screwed right there.
Then I seen how they were made back then and felt a lot better. I cleaned up the engine and it looks
good. Thought the boiler might have a cartridge heater and it does. The cord needs a new plug end.
Checked the continuity of the heater and its not open. I hope that means it will work seeing how it
just slid out the back of the boiler. Removed the sight glass, same style of holes as the steam line.
Removed the whistle, no gasket. Went to remove the SV, one of those big fat ones. Well it was epoxied
into place. Huston, scrub the mission until I get some input on what to use to dissolve it.
