Paddle/Wake views of the Liberty Belle

- This video isn't the most exciting thing to watch for most people, but I wanted to watch the paddle underway and try to capture the neat wake pattern that the paddle makes behind the boat. There is a pattern of peaks and valleys that follow the boat right behind the paddle. These waves extend aft a long way. I also need to find the best position to put the camera before I go to the lake and fire the boiler. I waited till the relief valve was blowing and she was itching to run to set up the camera. Not the time for that :)
This is also the first run on water since I disassembled the engines to anodize the cylinders and valve blocks. A bit of corrosion was found in the cylinder bore during the measuring process for the CAD drawing I made of the engine assy. The teardown caused the loss of all timing. I need to adjust some of the valve timing to get it running a bit smoother.

Bonjour,
Bonne Année ! Great way to start will this New Year with your wonderful singing boat !
To be continued :+)
Amicalement, Raphaël
Hi Raphaël, Happy New Year to you too !
Je vous souhaite le meilleur pour la nouvelle année! ( hope thats right )

I'm building my own live steam sternwheeler In g scale do you have any suggestions or advice I've built a haul out of 1/4 inch ply scrap and have now let it set in it's unfinished State for about a month now
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
That's nice close views of the paddle wheel in action Pete, well done!
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
What's it got under the hood? ;-)
Its powered by a propane fired boiler feeding twin double acting steam engines
I just found your videos on the Liberty Belle today and have looked at all of them and your build log. I'm really impressed that you tackled making proper Western Rivers steamboat engines and worked through the problems to get them to work at this size.
I've been interested in this design of engines since a trip on the Delta Queen in 1974. The valve gear, including the California cut-off, all made sense by just watching the engines for about five minutes.
I've made several starts at making myself a set of stern wheel engines and done a lot of research on them, although as you have found information on them is scarce.
I started again on building a pair a few months ago. They will have about twice the stroke of yours. These days it will be much easier than my attempts 40 years ago. Free 3D cad software, 3D printers, and resins that can be used for investment casting have all come together to make me rethink how I build parts for my steam models. What was only possible with complex fabrication or complex patterns and cores for sand casting is now much easier and gives more detail. I've cast a number of parts for my live steam locomotive and plan to use the same technology for the pair of steamboat engines. So far I'm to the point of drawing and printing a number of parts to see how they looked and would fit together but have only cast a few of the parts in bronze.
By the way, I got a good chuckle when I saw that you had referenced the web page on Western Rivers steamboat engines that I created 22 years ago! I created it when I couldn't find anything at all on the Internet giving describing this style of steam engine.
A suggestion for anyone wanting to build a Western Rivers steamboat model. Find a copy of "Western Rivers Steamboat Cyclopedium" by Alan Bates. Although there is little on the engines, there is a wealth of information on steamboats and steamboat modeling that I haven't found anywhere else. A note on the author - in addition to his interest in steamboat history he was the marine architect responsible for the design of the Natchez steamboat operating in New Orleans. In the past he also sold drawings of several steamboats for modeling purposes.
Again, nice work!
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 !!!
Pete
