Yep, Its moving pretty good but I didn't really go much past half throttle !

well at full throttle constantly its only about 3 min, but its usually 5-6 depending on how hard its pushed

Well im not sure what your asking, but here is what is happening when it runs. The incomming air goes into the valve in the center. That valve determines what direction the engine will turn and it also allows for a small amount of speed control. From there it goes to both cylinder assembly's spool valves. Those valves determine when and what side of both pistons gets pressurized relative to the crankshaft position. The cylinder timing is setup that one piston gets pressure about every 90degrees of crank rotation. This allows the engine to be self starting. The cylinders are double acting so that makes this engine act like a 4 cylinder engine. Does that help ? Mine runs really nice on steam fed by a propane fired boiler. Pete

Thanks! The little motor is there to spin a little propeller that’s in a pipe. It’s there as a backup to get the boat back if something goes wrong with the steam engine or boiler. It has been used a couple of times. Keeping a boiler and all that linkage happy isn’t always easy.

31.7 mph! The little boat really scoots !!!

Yes it is and is mounted in the m-jet designed 4G fiberglass hull

Mr Morris, I am really sorry I didn't see your post before today. I'm not very consistent at checking my channel. That being said thank you very much for a really nice post ! I am thrilled that someone that contributed to my project (as you did thru your web site showing nice detail of these great engines) found my little project. I would love to see your engine as it develops. Are you posting the build anywhere ? If not consider doing so. I had fun sharing my project and enjoied input that folks from all over gave me and I hoped to inspire others at the same time. I think your right, a 3d printer would help with the process. I have low end one now and it sure would have helped to quickly make temporary parts to get the configuration and movements correct before going straight to cutting metal. Casting sure would be nice too. Turning big hunks of metal to mostly chips took a lot of time and was fairly wasteful. ( especially the miss cut parts that seemed to constantly show up ) Bronze would be a much better metal than the aluminum I used. It all runs just fine but when I tore down the engines to measure them to put them in fusion 360 I found small amounts of corrosion in the bores of the cylinders. That prompted me to learn how to anodize at home. I treated the engines with that process and time will tell if it helped. The Delta Queen must have been great to see. I went down to New Orleans and rode the Natchez as you probably saw. It was fantastic. I also visited the steamer Portland in Portland Oregon but we didn't time it right to be on her during one of the excursions that happen from time to time. It was still great to see full scale machinery like that. The Disney Liberty Bell my model is patterned after it also a great ride to be able to sit close to the running steam engines and watch them push the boat around. An amazing example of model engineering in a sternwheeler if you haven't seen is Mike's W.T. Preston - www.rcgroups.com/forums/showthread.php?1497645-1-32-Scale-W-T-Preston-Sternwheeler-Build Any questions you might have about my model I'd be glad to try and answer Thanks so much !!!

If you do I’d love to see it !

@@DeltaAPmech thank you! cant promise, but once i get these manualscript done. i may try.

Bear was the inspiration ! You have great video of riding the boat at a much higher quality on your channel and I thought it looked so neat I had to try to do the same. The surgery on the moose made smiling a bit hard for him to do now😬 I definitely didn’t want to make a video of that process……

Hey Wes, I think the belt drive lathes are neat looking but I have never used one. I did all my work on one of the Chinese harbor freight type mini lathes. It did fine for me but it can’t handle much more Than that little engine I made out of mostly aluminum and brass. It has a hard time with any real metal.

Yep the first speed control for the power feed was just an old train controller from when I was a kid. I built a dedicated control for the power feed later on. It is currently used as a control for a hotwire foam cutter That tilting column has come in handy a few times but your right I have messed up and moved the column with heavy cuts and or chattering and goofed up plenty of stuff because of it !😀

Yes the connecting rods are at 90 degrees to each other. Its setup that way to enable the two cylinder engine to self start at any position the paddle shaft/paddle happens to be in at rest. Because of orientation of those rods the power output of the system was not very even through the cycle. I had to play with the cam timing and valve durations of both the intake and exhaust to try to get the paddle to turn at a consistent rate. The other fly in the ointment was the boiler water feed pump. It takes a good bit of energy to operate and it loads down the engine on its compression stroke quite a bit. It took lots of fiddling and trial/error to get it all turning at a consistent rate. Turns out putting the paddle in the water smoothed out the movement of the paddle even further. That was a nice accidental find :)

​@@DeltaAPmech I bet you pleased with yourself now it all turns about that workmanship you have explained well. Thank you for sharing this. I just bought a book called Rivermen and that was published in the 70's, in which you may agree a good find - all leather coated too. It had one neat drawing inside of a steamboat paddle wheeler she was called Far East, well I build model boats for a hobby and it was intriguing to find online UA-cam of the mechanics of this newer as first seen insightful contraption to which yours I found was the best video thanks. Yes I agree with what you are saying the precision must be spot on; plenty food for food on the engine type however is that one stroke? With what you are saying also I guess there were quite a lot of trees cut down to run the steamboats momentum, perhaps not the ideal solution nowadays though no one can ignore the steam powered engine. A very simple design in Engineering anyhow you maybe interested to know even further President Lincoln was involved in the first designs. Though these boats never lasted long typical of habitat nature surroundings and, those grasshoppers were something else to low river bank warnings get over almost all.

@@glennnicholas1602 Sounds like a neat book. This is a twin cylinder double stroke setup. Each cylinder pushes and pulls. Yep, I'll bet lots of wood was needed ! Coal was used too and now the few remaining ones use fuels like oil and cng. These things aren't the most maneuverable boats and rivers full of logs stumps and sandbars took their toll ! Still with all their inefficiency's and short comings compared to todays standards they cant be beat for character !!!

Me too! Steam engines have a lot of character.

Hi Raphaël ! Thanks it was fun to build. I thought about building a steam launch but the cost is what stopped me. Big boilers and engines are expensive and I don't have the tools to build at that size. It would be fun to have one Pete Google Translate version - Salut Raphael, Merci c'était amusant à construire. J'ai pensé à construire une chaloupe à vapeur, mais le coût est ce qui m'a arrêté. Les grosses chaudières et moteurs sont chers et je n'ai pas les outils pour construire à cette taille. Ce serait amusant d'en avoir un Pete

Thanks Wes, only if you count my little arms pulling on oars as unusual if I can get the wind to do the work. I have seen a couple of guys mount the drive part of a trolling motor to help out with the fun

Thanks Gary ! I hope I can figure out how to let the wind move do the work !

Its powered by a propane fired boiler feeding twin double acting steam engines

Thanks ! I just hope my first scratches and dings don’t bother me 😁

Thanks ! I really like Gary's design now I just need to learn how to sail ! The retracting keel/rudder really help getting the boat in the water. Its a bit tippy when retracted, so the sails stay loose to the wind ( don't know the nautical term :-) ) till it gets to deeper water

Not sure what kind of engine you are asking about. This one has two double acting cylinders driving the paddle, so I know how they work

It really is a very different place isn’t it ! It was something I had never seen before. There are even alligators in the lake. At least that’s what the warning signs said !!!

sorry for the delay I missed this comment somehow, Thanks it was a LOT of fiddling with valve timing to get it to run that well.

Hi Raphaël ! your right, the gas bottle needs to be replaced with something that looks better. She does have a whistle, but I didn't manage to use it during the video, oops !

Thanks !

Thanks !

sorry for the delay I missed this comment somehow, Thanks for the complement !

Mr Hodgson, I don't have to look up your steamboat engine plans because I am familiar with your website already ! When I was thinking about making this engine my searching lead me to your site. Your design is the only one I could find for a model sternwheeler engine. Going by the description and the few pictures I could find the engine you have is considerably more complicated and much more to scale than my simple design. My email address is pcmastan@hotmail.com if you want to contact me. Pete

Sorry I missed this comment ! Thanks for the complement it came out nice and its a little different viewpoint

@@DeltaAPmech It is! btw, great workmanship building that Dory kit, Pete! Have fun learning to sail! Peter

Hi Raphaël, Happy New Year to you too ! Je vous souhaite le meilleur pour la nouvelle année! ( hope thats right ) Pete

Hey Wes ! Well off the top of my head, I was advised by a fellow boat builder to add a couple of strips of wood on the bottom of the hull to help with tracking on a flat bottom boat. Mine are about 1/2 inch deep made from 1/8 ply and run the length of the flat part of the belly and each one lines up with a set of rudders. Research about the full scale sternwheelers showed me that two sets of rudders one set forward of the paddle and one set aft would give the most control in both forward and reverse. I never ran without all four rudders but this big boat turns really nicely ! The added bonus is they hang just a little lower than the paddle and give the paddle wheel a bit of protection. I'd love to help with any questions you come up with. Hope that helps Pete

@@DeltaAPmech thanks this is the first video I made on construction ua-cam.com/video/L-bN_fr8lzg/v-deo.html

Thanks ! It was a lot of fun to build. It is based off of pictures I found of the full scale engines from long ago. Here is a video of the boat on the water under steam. There are several more videos of it on my channel ua-cam.com/video/BSn42yYE9_A/v-deo.html

Thanks ! Sorry for the delay I missed the notification of your question. I cant remember for sure, but looking at my pictures it seems like It took around three months for me to machine the parts and build the engine. I posted the process here - www.rcgroups.com/forums/showthread.php?2759179-A-Smaller-Steam-Boat The engine work starts on the second page near the bottom.

@@DeltaAPmech Thanks, it´s super interesting to see the process

There is rubber still stuck to the fender and bumper ! It was fun once but Probably won’t happen again, I don’t want to fix what will break !

All those hot rod car shows on tv are a bad influence !!! :)
