Hydrostatic Lubricator Drawings

This as a real L-O-N-G shot: Does anyone out there have a set of drawings I could get copies of for the 1.5" scale Detroit Lubricator described by Basil Palmer in the October 1991 issue of Model Engineer magazine. Mr. Palmer offered free drawings of his hydrostatic lubricator design to anyone upon r...

Re: Formed cab roof angle 16 ga. steel

DaveD, I see you had problems with the roll forming of your cab rib. I'm glad you were able to make your rib using one of the other processes. The roll form process will work. But, it does tale some technique. I've seen 3" steel angle iron successfully rolled into arcs. The helix or corkscrewing tha...

Re: Steam Dome Throttle

I use a tapered plug 'pull' throttle in several of my locos and find them very easy to operate... You can also consider having a small orifice I the throttle to keep response under control. My 1-1/2 camelback has a 3/16" hole from the throttle to the 2" diameter cylinders and 9" drivers...the tip o...

Re: Steam Dome Throttle

The reason I've been so concerned about low speed operation is I'm modeling the NYC 999 in 1.6" scale. The drivers end up being about 11 3/8" diameter. A scale 100 mph is an actual 13 mph and the drivers would rotate only 390 rpm. At an actual 5 mph, which is pretty fast for most live steam tracks, ...

Re: Atta Boy for Eccentric Engineering Injector

I'd also like to add my thumbs-up to EE's injectors for fast service and an excellent product. I installed one of the small injectors on my Disney 4-4-0 last Spring and it operated flawlessly through out the Summer. I had previously used a Super Scale economy injector. It also worked well but was ov...

Re: Hydrostatic Lubricator

Dave, since 25 years I'm using a sight feed lubricator on my 2.5 scale NG engine "Tobi", successfully and without any trouble. The oil tank and the oil sight feed fittings were bought finished from an english supplier. My lubricator steam stop valve is connected directly to the steam turret. I'm us...

Re: Hydrostatic Lubricator

@ jessebanning unfortunately, the videos are not very clear. Your design looks like the SIGHT-FEED LUBRICATOR in J.G.A. Meyer's book (Modern Locomotive Construction 1892, page 556) . I miss (or couldn't see) one very important feature on your design, the (needle) valves, which regulates the quantit...

Re: Hydrostatic Lubricator

We will be offering a 2.5" scale version in the very near future. I have attached some photos and video of the prototype working the bugs out. https://www.youtube.com/watch?v=OGths6wONbQ https://www.youtube.com/watch?v=KJ3NfMcj48s https://www.youtube.com/watch?v=OGths6wONbQ Is the drawing of what a...

Hydrostatic Lubricator

I'm fitting a hydrostatic, also called sight feed lubricator, to my 1.6 scale NYC & HR 999 project. I know mechanical lubricators are simpler to install and operate. But, hydrostatic lubricators were used in 1893 and I'd like to try to make one work. I made provisions in the cylinder block for a mec...

Re: Steam Dome Throttle

Check out how I handled the ball valve and linkage here: http://www.chaski.org/homemachinist/viewtopic.php?p=338835#p338835 I've built two this way and they work great. Used an off the shelf 3/8 ball valve from Ace Hardware and all stainless materials for the rod and lever. Hmmm, that has possibili...

Re: Steam Dome Throttle

Thank you to all of you for your ideas and insights. I believe my steam dome and throttle rod is a bit different that most as the turret pipe enters the rear of the dome and the throttle rod goes down through the center of the turret pipe as shown in the attached photo. The dry pipe enters the dome ...
