Rick H. You have put a lot of thought into your projected steam car. One of the keys to the success of the early Stanley steam cars was their light weight. The early 1904 Stanleys weighed in at 770 pounds. By the time that they had the fastest muscle cars of that era, 1,600 pounds was the scale weight of the 1908 H5. Light weight is one of the keys to having a fast and nimble car. By 1915, their weight had exceeded 3.400 pounds and they had become slugs as compared to the IC cars of that time. Condensers were mandated by many municipalities, and the condensers were the main reason for their weight increase. As far as blending old and new designs to create your steam car special, blending designs is the easiest road to take rather than duplicating a historic vehicle. Unfortunately, the blended vehicle will not give the equal amount of return on your invested dollar as compared to duplicating a historic vehicle. If having a good return on your investment is not a criteria for building your steam car, then there are hardly any restraints to your blended designs. What has been accepted in updating the vintage reproduction vehicles are adding disc brakes and using modern metals. Modern bearings, modern insulation, updated burners and boilers have also been accepted in the vintage reproductions.. I wish you the best in your project. Keep at it and it will soon get done. Time is a wasting!

Hi Pat, hope all is well with you. I'm dedicating every Tuesday (evening) to build my replica of a 1908 Stanley H5. This will be a blended vehicle as you state. I will be developing and trying out new, modern steam technology. This is to satisfy my desire as an inventor. However, I hope to show up to backyard car shows, steam get togethers and have people identify this car as a 1908 Stanley. My intention is to give impressive rides to show off my capability as a designer, inventor and capability in understanding steam power. I'd like to run with you, along side in a Steam Car Rally. The only original part will be a 10 Hp Stanley dry engine that would be used on a 1908 Stanley EX. One of my top design inputs is to keep this car light. I have decided what new inventions will be incorporated into this car. They will come out as I show progress. As a side note and as an engineer, I have to be careful not to fall into analysis paralysis. This stops all progress.

To all, this project is to build a fun Gentleman Speedy Roadster. It will have a 10 Hp Stanley and incorporated into a shortened Ford model T frame. The frame is identified as one of the earlier, brass era, vintage that came with 30 inch wooden artillery wheels. The frame was 100 inches in wheel base length. I shortened it to 84 inches. The reason, original H5 has 33 inch wheels and a 20 Hp engine that was 3-5/8 X 5. My spec is 10 Hp (3 X 4), 30 inch wheels and 84 wheelbase. This will give the look of the original Stanley H5 as a close scale model. My modern updates will make it a real performer...I hope, we'll see.

Attached is a picture of an H5, the end game. Next picture is the frame now on saw horses in my workshop. As one can see, the shop is still in it's completion stages. I get the electric inspected tomorrow as a matter of fact. I will have a pretty complete machine shop with Lathe, Mill & welding capabilities.

The rear portion of the frame is where I shortened it by removing a precise amount to yield the 84 inch wheelbase. The frame was then overlapped, nested within itself and welded. The pieces that were removed were welded to the front portion to support the boiler. The boiler needs to fit within a 22 inch width.

Note that great thought and planning is going into this build. I have lots of drawings and calculations to come up with this design. If any questions, please don't hesitate to ask. I probably haven't thought of everything. Part of my research includes combing Rolly's EX duplication and build (steamcar.net), Colburn Bensons H5 (now sold) and Jim Anderson's 1908 Stanley EX. I humbly admit that I have a lot to learn about the details...yes, the devil is in the detail.

Hope this interesting and inspirational,

Kind regards,

Rick H.. I have been on many steam car tours over the last 36 years and many of the steam car tours had modern, and also cross bred steam cars on them. Peter Barrett is one that had a good performing modern steam car. He attended several of our steam car tours with his VW based steam car.. Not all clubs allow modern steam cars on their tours. If you do your best to keep with the H-5 image, then blending into a vintage car tour won't be so much of a hassle. The wife and I have had the most fun steam car touring all by ourselves. We stop for water when we need it, we make adjustments when we need to, and we don't have to wait for anyone.

Rick, I don't want to come across as being an ass, but I put up a building in my yard when I was in Michigan, I used the same insulation I see you are using. I found out the hard way that putting the insulation in contact with the sheet metal siding causes condensation to form on the metal. I redone mine and put the insulation against the two by fours to leave an air gap between the insulation and the metal. No more condensation build up. Insulated my building in Tennessee the same way and it stays dry. Dan

Hi Dan, I appreciate offers of wisdom from practical experience. As a quick aside on the pole barn, I use this stuff known as 'Double Bubble' that is against the steel sheet metal. The double bubble has a shinny reflective surface, reflects IR and acts as a vapor barrier. Then the foam sheeting. Then another foam sheet over the girders. All joints are taped with the aluminum shinny tape, again, reflect IR. My electrician buddy stated that I'll be able to heat the place with a candle.

I hope this H-5 build will be state-of-the-art. The barn is also in that it will be heated with direct geothermal, hydroponic radiant floor and a rocket waste oil burner of my design. I'm big on infrared (IR) and firmly believe it is in our future. I hope that my article on IR comes out in the SACA Bulletin this coming issue. No doubt that IR or radiant heating transfers energy far more efficiently than convection.

Back to the H-5 build, IR is one of the planned items to be incorporated into this intended speedy machine. Sorry for the teaser, to early in the build to show the details. The burner conversion will be based on the method used and shown in the Bulletin article. The burner is designed and built. However, the blue will be converted to red. Note that I show pictures in this forum of this IR development.

Thank you so much for your offering and hope you enjoy the build,

Kind regards,

I'll be watching your progress. Looks very interesting. Glad you got a good plan for the insulation. I couldn't see the vapor barrier you have in there. Just had to stick my nose in your business . Dan

Dan, no problem, I appreciate folks with practical experience. Please enjoy!

To All,
I'm setting up for the split of my T rear end this coming Tuesday evening. I'll be bringing the rear end to the Barn and spraying PB Blaster. I'm toying with using a transmission fluid and acetone concoction...anybody's thoughts?

Attached is the model T as I bought it. It did come with steering wheel and column. Can you imagine a beautiful coffin nose on that baby.

Cheers, Rick

After you Sandblast it clean and prime it weight till you finish the car.
The banjo frame and chassis of the car will get the most abuse from road use. Find a good paint that you can also get in a spray can for touchup.

The yellow undercarriage of my Stanley is a John Deer tractor yellow that matched the yellow of an original Stanley hub after wet sanding by a computer matching machine. It also came in a spray can. I can wet sand a chip spot and touch up a spot.

Hi Rolly, thanks for the advice. Also thanks for this fine work...

Rolly's Stanley EX

I looked at every picture and drawing. My build is really an EX with the look of an H-5.

Tuesday night Progress Report: one can see the comparison of a model T rear end to a Stanley EX. When I bought my 10 Hp Stanley engine from Robbie, it included this ~ 1906 EX rear axial.

The splitting of the T rear end wasn't so bad. The challenge now is to blend the 10 Hp Stanley to the T rear end and make it look cool like a copper cladded Stanley EX rear end.

My initial thought is to make the pumpkin support brackets like the Stanley and fit to the T diff. I'll need to keep the outer portion of the T axial to maintain the trans spring suspension arrangement. Admittingly I don't have the final plan in mind nor on paper. I'm confident I'll get there.

As a quick aside, does anybody have details of this gentleman who made two Vanderbilt Racers and used Jaguar rear ends?

This is a bronze casting for the gears on the EX rear end. A friend of mine now dead
made some of them. Gears available from Boston gear. Somewhere on my old hard drive I have the numbered gears. You need to pick the one that matched the engine gear. Looks like you need axel gears, they will have to match differential three gears.

The gears are Browning YSB10B15-40 for the stars and Browning YSB10B60-40 for the axles. I am not sure the 1 should be I or the 0 should be O, but this should get you close.

Progress report from last night. Figuring how to use the model T inner rear into the EX rear end. In deep thought on how to support spiders and driven gear. The model T inner workings fits within the EX rear end/axle. Still need a driven gear solution. confused smiley

I decided to go with a Boston Gear, and machine it. I have a cast iron Stanley carrier I purchased from Ron Rodgers.. I'm pretty sure the model T spiders will fit. Thanks to Rolly for providing a lead to an outfit in the UK. With the Pound Sterling conversion to USD, not so good at this time. I hope to get my mill set up soon and start the machining process. Also, get the gear on order...all for now.

Picture of Tony's Delora Buggy rear end. His is a model T conversion. Also, picture of the 10 Hp driving gear, currently disassembled. As a point of reference, my 20 Ton Press was able to push this apart.

Latest update, I received my driven gear from Boston Gear. It's a beast! Now time to set up and do some machining...

Note that my driving gear is pictured also on the 10 Hp Stanley crank shaft. Cranks removed. I measured the driving gear to be sure I ordered the correct gear to surround my rear cage (holds the spider gears).

I find it neat that it's a genuine Boston gear. Some of the auto magazines from around the year 1900 had Boston gear advertisements for differential gear sets that they were selling to manufacturers and home builders. Neat to see the company still contributing to the field way over a century later!

Babs Foundry Inc in Norton Mass made all Boston Gears bronze casting for the last 100 years that I know of.
Tony Borges for over 70 years and his son David for the last thirty years. I don’t know about the iron but I’ll bet it’s one of the iron Foundries in RI

Babs also make some of the smoothest cores I know of; and for other Foundries as well, when I cast my high-pressure pumps they made the cores for Cumberland Iron Foundry. I had supplied my core boxes to Cumberland and they went to Babe foundry because Babe did better work.

Not two far from you Rick.

I have a cage casting from Ron Rodgers that potentially can hold my spider gears. If not, I may check out this place near me.

I just brought home this rotary table, bought from my company for scrap cost...imagine that! This will be used to hog out the web in the Diff Gear. It is a high precision rotary table.


PS, I would love to see you at the SACA meet my friend, Sept 17-19. Any chance I can twist your arm and have you come up? People are bringing some nice hardware: Tony, Jerry, Chuk and myself and more. Gonna be lots to see and talk about!

Nice table both horizontal and vertical.

How big in diameter is the table?

Re: Gentleman Speedy Roadster Build

10 inch, should carry the gear well.
