Joe Fedullo has now produced a batch of new style Jets for Stanley type vapourising burners, which he describes below:

I have been playing with Jet designs and think I came up with something that might be better than what is currently available commercially.  Take a look and let me know what you think.  

Changes to the exit tip:  

     On the outside, the simple 3/8" hex is replaced with a smaller 5/16" hex that has a smooth taper down to the nozzle exit.  The idea of the transition is to smooth flow of the entrained.  Herb de la Porte has observed eddy currents around standard jets at the nozzle and this seems like a way to help rectify that.  He also has a set of old jets he found somewhere that have a similar design.  He lent me one I used to copy the head.


     On the inside, I added a 5 degree taper at the exit of the inner hole to create a diverging nozzle.  Since the flow is sonic and therefore choked, the diverging nozzle should allow further acceleration of the fuel flow and hopefully more air entrainment.  I used about a 2:1 area ratio for the diverging nozzle assuming a #56 jet.  With smaller jets, it will be a expanded a little more.  I then added a 1/8" radius right at the exit after the taper to help the "pricker" find the hole, but hopefully these don't need to be pricked very often due to the changes in the backside of the jet 

Backside:

   Even though I use the multi port jets from Vintage Steam, I have noticed when the rearward centre hole clogs, the flow goes way down even though there are 12 other holes for it to go through.  A simple prick usually opens things right back up and I have never seen the radial holes clog when I remove the jets.  I took some measurements and the diameter of the holy section of the current multiport jets is 0.196" and the drill for a 1/4-28 hole is 0.213 so there is only 0.0085" radial clearance for fuel flow.  That gives about 0.0055 sq inch of area which is almost 4 times my # 57 jet area, (# 57 = 0.0015 sq inch) but empirically it doesn't flow when the back hole gets plugged.  Maybe there is a boundary layer issue with such small clearances, or maybe carbon dust plugs up the circumference.

     To help, I made several changes to the backside of the jet.  First I reduced the minor diameter to 0.175".  This should allow much more flow to get to the radial holes perpendicular to the main flow axis.  The other big change was the addition of 6 holes on the tapered surface around the main rear hole.  These holes are perpendicular to the chamfer pass through the axial hole and also open to the cylindrical surface.  I would think these holes eliminate the need for the radial holes, but I started thinking they all converge at a single point which was a potential area for a blockage so I added a dozen radial holes as well.   The back of this jet is now Swiss cheese...

It looks like a pretty tricky part to make, but my first preliminary quote came back at $10.06 each in a quantity of 100.  Before I get deeper into the quoting process, I wanted to get feedback / see if you guys have any design change ideas.  Also if anyone is interested in splitting up the order I can keep you posted as I work through the quote process.  

I've made a couple of changes based on some great feedback, which I really appreciate. I will wait a couple more days for further feedback then send them out for production:

1) I've increased the length of the bullet shaped outer tip per feedback from Howard.

2) Changed the spacing of the holes perpendicular to the chamber at the fuel inlet, such that they all do not intersect at the same point giving a potential clog point.  They are now in 2 arrays of 3 giving 2 intersection points.

3) All holes are now #66 which was the smallest size anyone I know uses.  They can easily be drilled out to any larger size needed.

​This weekend's progress. Because it's my first attempt, I didn't get everflex/bison vinyl and opted for a UV treated vinyl on sale instead. It is much softer and super stretchy in comparison. And I recommend just getting the good stuff cause I have to compensate on a few things. I used a multipurpose adhesive spray to attach the lining material- I can now forget about securing the layers for the rest of the project. On the parts that were used as bracing or interfacing, I will be adding a layer of a heavy interfacing to combat the vinyl stretch. The back's 3 panels are complete minus hardware.

We regret to report that Brent Campbell, one of the most prominent members of the Steam Car Community, passed away on the 24th October, after a long illness. Brent had been around Stanleys since the early 1950's, when he rode in his grandfather George Monreau's (who had worked for the Stanley Factory) 1913 Model 65. A keen driver, Brent believed in using his car's rather than just displaying them; his first Stanley clocked more than 35,000 miles in the 13 years of his ownership. Indeed, in his Stanley model 85 he clocked 424 miles in one day, and regularly took part in the Trans Continental  and Red Rock Tours. 

He was an absolute authority on Stanleys, and was a great help to many Stanley Owners, always offering help, as well as historical information. Indeed, his contribution to the Stanley Steamer Book, written by Kit Foster,and produced by the Stanley Museum, was invaluable. 

Brent was not a person who believed in the brake pedal. In 2006, the Buick Hot Rod he owned crashed when a rear tyre blew, throwing the car firstly into the central reservation, then back across the highway to the nearside followed by five somersaults, destroying the car. Brent suffered multiple injuries in addition to three vertebrae in his spine needing to be frozen together. After a long rehabilitation period, Brent was back driving his Stanleys. 

Brent had a great collection of steamers over the years, including a Stanley CX (sadly lost at the bottom of the Atlantic after taking part in the centenary of the London to Brighton Veteran Car Run, when the container ship broke in two), a Stanley Model K, a Stanley Model 74, a Stanley 731, Stanley 82 and Stanley 85. But perhaps the cars he is known best for are the two Raymond Stanley Specials he owned, Effie, a 1911 30HP Roadster, and a 1912 30HP Roadster, the latter a painstaking multi year recreation by Brent.

With Brent, alot of Stanley and Steam Car information passes. He will be sadly missed.

Yesterday the Stanley's engine/rear axle assembly came home from the brake shop. It's now sporting two new disc brakes in place of the old band brakes.
Today begins the process of reinstalling it. Lots of little things to remember along the way!
Once in the car the engine will get a bath of Gunk, then the crankcase cover will be installed (with new gasket, of course!)

​Steam Car Enthusiasts,
I wanted to reach out and announce the 2021 Midwest Steam Car Tour.  We are shifting the tour days slightly from past tours.  We will be touring starting on Saturday September 11th and the final tour day is Thursday September 16th 2021.  The tour is based out of Cedar Rapids, IA and the host hotel is The Hotel at Kirkwood.  You can book your stay at the hotel by calling 319-848-8700 or toll free at 877-751-5111 and ask for the Midwest Steam Car Tour block.  The hotel only has a little over 70 rooms but has a very large parking lot for trailers.  We hope you will join us for a nice roads tour.  More details to follow.  We are excited to see everyone out touring again. 


If you have any questions, please feel free to contact me by email or phone below.


Thank you,

The 2021 Eastern Steam Car tour is underway, with the first two days having taken place. Photos courtesy of Billings Cooke, Sarah Moon, Herb de la Porte, Steve Bragg, and Mark Turner.

Thank you to Ian Larcher for providing us with these fascinating pieces of Literature on White, Locomobile, American, Crossland and Vapomobile Steam Cars. 

Billy Barnes has almost finished this 1910 Stanley Model 60, just awaiting paint.

My new water pre-heater which uses exhaust steam thru heat exchange. The water side has water from the water pumps to boiler. This is so you can use heat from the exhaust steam to heat the incoming water. This helps greatly as your not putting cold water into the boiler.

Here are some photos of the cars Bill Barnes has recently been working on.  A Stanley 740 tourer, 731 Roadster, SV Sedan, 1914 Stanley 606, and a 1923 Stanley 740 Roadster.

I’m rebuilding a 20 HP Stanley engine. The block was apparently operated with too
little steam oil and the valve seats were damaged as well as a bronze repair was attempted with poor results.
This repair of the worn valve seats uses a machined steel plate and high temperature silver solder - very pleased with the results. Gilbert Hall and Rempco did the work. My crank gear also had a broken tooth, I had a NOS gear that was pressed on.

This weekend just past, saw the first steaming of the year for my Stanley 726 that I was lucky enough to acquire just a few months ago. Greatly encouraged in the purchase by George Hounslow having spent the New Forest Tour navigating for him on his Porter Steam Car. I am incredibly grateful to George and his parents for then leading the recommission of the car, sorting out a number of jobs associated with wear and tear, as well as preparation and arranging a hydraulic and steam boiler test. A number of safety improvements/replacement parts, not to mention extremely good tuition in maintenance, management and driving! After many weekends work from myself but 10x more from George, we had a very successful 3 days cruising around Wiltshire in some pretty challenging terrain at times. The Stanley performed faultlessly and I really couldn't be happier with it! Here's to a busy 2020!
Unfortunately the weather has been rotten and the roads are filthy so the car got quite dirty, the photo below was taken Sunday morning. However, Sunday afternoon was spent in the garage cleaning for a few hours!

Today we ( Arnoud Carp and Roel Rasker ) assisted Philippe Mulders to get started with his model 60 Stanley in the city centre of Maastricht.
Philippe is new in steam but after a few hours he was able to start the car without any problems himself.
This now means there is a beautiful, unspoiled, original Stanley in the Fineautomobiles Collection in The Netherlands.

Can anybody help with a drawing for the stub axle for a Stanley or Locomobile buggy?
If so Please Contact Udo Joerges via ujoerges@aol.com.

​Engine rebuild progress...the block, piston rods, crank assembly, heads, are all shipped off to the machine shop for machine work. The block will be bored and new pistons made (new rings too). The piston rods will be hard chromed and thread repair done...finally the crank gear will be replaced (chipped tooth) with a new old stock gear.
