Atta Boy for Eccentric Engineering Injector

Post by Pipescs » Sun Jul 01, 2018 7:53 am

Just a short note for anyone considering dealing with Eccentric Engineering.

In reworking the L.E. American I decided to add a small injector as a alternative to the hand and cross slide pumps.

As the American is small to say the least I was looking for something that did not look out of place under the cab.

My first attempt was a small injector from Blackgates in England. They are small and not very expensive.

Long story shortened. It did not work as advertised. Although it had a test certificate that said it had been tested to 100 psi, myself and two other members at Mid South could only get it to pick up between 40 and 60 psi and even then it was intermittent to say the least.

Pontiacguy convinced me to come off the pocket book and order one of the small injectors from Eccentric Engineer. Cost was $250.00 with free shipping. He offers this small injector with either quarter inch or three sixteenth connectors. He was nice enough to do a mix for me as I have quarter inch water lines in and 3/16" steam and water lines out.

It was an easy swap with just a small amount of redo on the piping. Looked appropriate for the model and works like a champ. I set it up on the stand outside the shop and pumped one and a half tender tanks of water thru it. Pressure was from 40 to my pop off at 105.

More importantly, from the time I place the order to my door step was two day. Later in the week I realize there are small parts I may loose when cleaning it and these also were delivered in two days.

A pleasure to do business with.

I installed one on my LE American a couple of months age and was REALLY impressed with how well it worked. I had a bit of a time getting it going and had to re-do the piping a couple of times (http://www.diannebest.com/Plumbing/ReFi ... rican.html) but once everything was right, the EE injector is dead-on reliable! Just make sure you blow out the plumbing with LIVE STEAM, not just compressed air - there are some tiny passages in there and they will pick up microscopic debris!

The problem with the English injectors is they are rated at 100 pounds Sterling!!!

I imagine that the English injector would pump to 100 PSI, but they seem to be so finicky that you'd have to have almost the exact same setup, mounting position, check valve, starting valve, etc... that they used while testing it out.

I had one before, and it would work from about 50 PSI up to about 95 PSI, and no further. At 100 PSI, it would refuse to start at all. In fact, at anything over 90, it was very difficult to get to start, and I never could do that while out running. It worked best between about 60 and 80 PSI, and that sucks when your pop-off pressure is 120 PSI. I re-worked the piping about 3 times to make sure that it wasn't the problem. I then bought a SuperScale Economy to replace the English injector. I used the same piping, just adapted/bushed to the SS injector, and It worked great, except for the fact that it was really too large and I could only leave it on for about 7 or 8 seconds at a time! It would fill the 6" boiler on that Chloe really quickly and the pressure would drop by about 20 PSI.

Glad that Charlie's injector worked really great. That will be a big asset to his locomotive. I second his sentiment about dealing with Anthony at Eccentric Engineer. When I've ordered something, the service has been outstanding.

Oh, is that what it is!

I come from a background of full-size steaming and never encountered an injector that didn't work - some of them had their "eccentricities" but they WORKED! (If they didn't, they would have been trashed decades ago.)

I built a 1/2 scale traction engine in 1995/96 and tired 2 or 3 British injectors but was never able to get any of them to do anything but blow steam (even down the pickup line!) It took a few years to find them but I finally ended up with a 1/2" and a 3/8" Pemberthy and they were totally reliable.

I never met a model injector that was anything but junk though a couple of guys in our club were pretty good at building them.

Than Anthony came along with the EE injector and I am beyond THRILLED! After sorting out the issue with microscopic debris in the lines, it has never failed to pick up and deliver the first time and every time! It has more capacity than my 1-1/2" American needs but I wouldn't trade it for the world.

...... just one old woman's opinion :wink:

Diane,

Do you have a filter in your water line?

Yes, an automotive fuel filter designed for fuel injection - very fine mesh.
