Hi Jeff,

By the looks of the bottom of the old tank, it may have been painted. Do you have any manuals or literature that my indicate wheter or not it was painted? What about painting it and making the paint look old?

I did take a new tank and wipe it down with a solution of diluted muratic acid and that worked fairly well to age the tank. Before you try that you need to clean it with a good detergent. The oil on the metal will cause uneven aging or etching as the acid will not react as well on areas that are oily. You may get an uneven aging/etching process. Be careful though as the new galvanized material is not as heavily plated and it could eat through the galvanization to the metal. I suggest trying it on some test pieces first. You can not reverse the process. Good luck and keep posting.

Joel, if you click on my avatar, you will see a larger view of the color R&V illustration that I believe is my exact engine. Per this illustration, everything was painted green except for the cooling tank. This would be consistent with the green paint we've found on parts of the wood that were more protected from the elements. I believe the green paint on the bottom of the tank is from the floor boards under the tank.

Thanks for the suggestion!

Received the top cone to the screen cooling tank for Christmas. John Wanat did an excellent job in copying the oirginal off our 7 hp R&V! It's a fairly complex piece...the inner cylinder has a solid bottom that fits snug on the top edge of the screen. It's walls have holes for the water to run down the screen. The outer cylinder is solid and angled slightly to match the screen.

The following photos show a blacksmith's attempt to repair a freeze crack in the R&V's water pump. Only the pump was damaged as there are no freeze cracks to the engine. I assume they forgot to drain the water pump or leave the drain open.

The pump had a crack about 5 1/2 inches long beginning at the mounting flange for the pipe to the cylinder. Following the break, an additional hole was drilled off center and threaded for another drain cock. Behind the mounting flange a one inch strap was riveted to one side of the pump and then bent around the pump to hold the broken piece in place. Two small metal straps were riveted to the main body of the pump while the opposite ends of the straps were riveted to the broken portion of the pump. You can see a small hole with the markings of a square headed nut. A hole was drilled through the broken section into the main body of the pump. A small bolt was then put through this opening, thereby holding the broken part of the pump to the main body of the pump. Following the repair, a sealant of some sort, maybe roofing tar was smeared on the cracked areas of the pump to keep it from leaking.

Here is the water pump after new weld repair, also by Tim Meaden of Slayton, MN. May take a little work / time to blend in the repair, but other than that, looks like new!

Over past month or so, we've been striping down the engine.

First two photos show the platform for the cooling tank and seat/battery/tool box. We cleaned up one of the boards and found that they are southern heart pine, which was used a lot for flooring, etc. in the late 1800s and early 1900s. A little difficult to find these days.

Next two photos show the brackets for the foot rest. It appears that we have matching brackets vs. opposite brackets for each side of the frame. Unless they made them this way?

It is interesting to see that the muffler is different externally but almost identical internally to the Triumph Line mufflers.

Patrick, the muffler is also similar to their early mufflers as shown our 6 HP R&V, but these had sharper edges.

Martin Reed made a new shaft for the water pump's impeller, nice!

Default Re: Root and Vandervoort 12 HP Portable Engine Restoration

I recently picked up this large cabinet photo of a portable Root & Vandervoort engine. The engine is basically the same as mine, except it has the water hopper versus the optional cylinder plate and screen cooling tank. The seat is also placed further back on the cart without the cooling tank. Hard to tell the size for sure, but even looks like a 12 HP!

The engine appears to be newly purchased from a farm implement store. You can clearly see the fancy pin stripping that R&V engines came with and the lettering on the cart frame. The sign in the upper left reads: Charvat & Hanus Cigar Factory No 47 Dist. of Neb. So I'm assuming this photo was taken in Nebraska, but not sure of the city. The photo is much clearer in person, but does have a few stains.

There are actually two engines pictured in the photo. Who can find the other one?

Looks like an Olds under or behind the corn sheller in the building. It looks like that is probably the implement store. The big doors are open and looks like they just rolled out the RV for a photo. Maybe it is a new business and they don't have a sign up yet. It looks like the second floor above the saloon may be the cigar place. I like the birds in the window of the saloon. Looks like if you got thirsty you could go over to the saloon, or go up stairs to the Commercial Club.

Thanks for sharing the interesting picture!

Tom, you got it right, you can see the hopper of an Olds engine inside the implement store in between the two gentlemen to the right of the R&V. In person, you can better make out a hanging sign for a maneur spreader above the Olds engine. I was thinking the same thing about the R&V being rolled out the door to the right. It looks like the door with the Cigar Factory sign leads upstairs as the far top left window has lettering for the same Cigar company. How bout the jacket on that one guy?

This past weekend, Dad and I stopped by Justin Jenkins place to check in on the R&V. It's coming along nicely!

Cart on blocks. Wheels are being repaired. Flywheels off. Head on the floor.




Piston is out.


Flywheels with resurfaced rims...nice!

Looking good. Very nice, unusual counterweights. One of dad's first bigger engines was a 10hp R&V sideshaft. It did not have a counterweighted crankshaft. Dad's had the cover on top of the cylinder like yours and he thought it was missing the hopper. Of course many years after he sold it he learned that's the way some of them were. His was a stationary with a subbase.

Dad and I went to Justin's place today to work on the R&V cart. The work to replace some spokes on the wheels was recently completed and the engine base was removed from the frame. We got everything cleaned up but the rear wheels. Working in a heated shop = nice!

Justin has made some great progress on resurfacing some of the R&V's machined surfaces. Here's the cylinder head:
