Roel Rasker recreates a 1915 Stanley Mountain Wagon. PART ONE After the restoration of my Stanley EX in 2017, I was looking for a new project. The choice soon fell on a mountain wagon. These cars have always had my interest, since my first meeting with Peter Williams's mountain car at the Dorset Steam fair a few years ago. First I started looking for an original mountain car. Because these were not available, or too expensive, I decided to build one myself. My preference was initially for a 1909 model with a wooden chassis with 3 benches. To be able to drive the car in the Netherlands, however, I had to work with an existing old Stanley chassis. Otherwise it was not possible to get it road legal in the Netherlands . That's why I decided to go for a 1915 model on a 735 chassis. It was important that I could find an old chassis whose restoration to the original model was not possible. In England on steamcarnetwork website I found a 735d chassis with chassis number. This was a great start to a big new project. I could also buy a 20 HP engine in England. With this I already had a solid foundation. In the future I might replace this engine for a 30 hp engine but first I want to see if the engine is strong enough. I had set aside 2 years for this project. But by working full time on it, I succeeded in half a year. I did a size study on the basis of photos of a 1915 MW, which in my opinion was quite original, after which I made a dummy body with a bench in plywood. These sizes were pretty good and with some minor adjustments I started producing the MW. Because this is a reproduction I naturally had some freedom to build the car the way I want. Among other things, more space between headboard and first seat, exchangeable seats, and a fixed propane gas tank for the pilot light. I also preferred copper gas lamps instead of electric lamps. The floor is completely flat so that the car can also be used as a pickup The convertible top is made of curved ash arches. The rest of the frame is made from various existing parts. An upholsterer has covered the convertible top and also provided the leather upholstery of the four seats. I had the bonnet and the fenders made at Vintage Wings in England. The fenders were perfect. I still had a lot of work on the hood. The company could not make the louvres. That is why I made a steel mold and punch with which I could apply the louvres manually. Roel

PART TWO After spraying I applied the pin strips with a Buegler pin striper. The MW has a 30 HP boiler which is made by the Goolds. This boiler produces enough steam for this car The pump pit is placed in the same place as with the 735. For the steam oil I use a Madisson Kipp lubricator. To transport the MW, I bought a closed box trailer that fits the car exactly. In order to be able to get on the road legally with the MW, it was inspected by the national road traffic department. This is always an exciting moment because you never know the outcome of the research because it is a special project. But still we managed to inspect the car within a day. I have now driven the first kilometers. I had made the connecting rod of the water pump too light. This broke off almost immediately. I am also still looking for the right adjustments from the burner. I am listening to every strange sound I hear while driving. And there are a lot of them. After every trip I get more used to the car. The boiler maintains good pressure and the fuel system also functions properly. After every ride I come across small things that are easy to solve. Building this car was a nice adventure. I have met nice people and learned a lot. The MW will be shown for the first time during the Melle steam event 2019
Roel Part three of the Mountain wagon rebuild. During the 400 kilometers I have gained a lot of experience with the Mountain wagon. The car was finished with a few details left to do, but these details were of great importance. During the journeys the throttle sometimes squeezed which made giving gas very difficult. I had made the throttle rod too short and throttle unit was engineered too tight. Now I have moved the throttle unit and extended the distance of the rod by approximately 8 cm. The cylinders were not yet isolated. A job that I kept pushing back because I didn't know how to make the copper casing. The insulation has now been applied. This makes a big difference in use. The water pump also did not always work properly. The check balls were worn. I replaced them with new balls and now it works properly.. To be able to check the operation of the pumps while driving, I temporary placed a pressure gauge between the water pipe on advise from another steam car driver. You can now see exactly whether the pumps work well during the ride. At the front, I have provided the blow-off valves with thicker brass spouts. This is only an aesthetic choice. .
The only adjustment that I am going to do this season is the application of disc brakes on the front wheels. Not beautiful, but effective. The hills in Melle were sometimes a challenge. Uphill - even with a 20 ph motor - is no problem. But to go downhill safely I had to use the handbrake occasionally and even then a emergency stop would be a challenge rolly`s stanley ex restoration4/8/2019 PART ONEFront axle details CAD Drawings in JPEG photoalbum\rolly\axle\4.5 BC Stanley Front hub as machined.jpg photoalbum\rolly\axle\axle assembly-a.jpg photoalbum\rolly\axle\axle end.jpg photoalbum\rolly\axle\Left Spindle.jpg photoalbum\rolly\axle\Perch pole and spring casting.jpg photoalbum\rolly\axle\Perch rod end.jpg photoalbum\rolly\axle\Spindle Pin and Parts.jpg photoalbum\rolly\axle\Stanley Hub Cap.jpg photoalbum\rolly\axle\Tie rod ends & small parts.jpg photoalbum\rolly\axle\U bolt.jpg EX Rear AxleThe rear end as built was modified slightly from the original. I have included the drawing as was original, and as modified. The axle ends were modified and built with five inch tapered keyed ends, and the drums were made to accept them. The bearing are deep grooved sealed ball bearings and are arranged so when the wheel is installed, tension and preload is applied to both the inner and outer bearing. No side thrust from the wheel is against the planetary gears. The gears used are original. The inner brake band cleaves and bolt was modified per the drawing so as to facilitate the ease of adjustment. The outer brakes originated in 1907 and I modified them by bonding brake lining material to the bronze shoes. All castings are 85-55-06 ductile, the axle tube is 3/16 - 4130 and the axles are 4140. The front axle is the same except for the spindle castings; they are A-148 structural steel 110,000 Tensile and 90,000 Yield and have tapered rollers for bearings.
