Any overhead type Stationary engine Smaller than Mamod Minor 1?
« on: October 02, 2021, 10:33:48 am »
Hello, I have been really enjoying tinkering/refine the smaller "hobby" grade engines as of late. I am wondering if anyone is aware of an engine that is even Smaller than a Mamod MM1?
  This video (not mine) shows the smaller Mamods in a row and the MM1 clearly is the "smallest" in this group.

  I am working on purchase of NIB MM1 but I wanted one with the sort of "Banjo" shaped green Meths burner, this one has the long rectangular Meths burner which I feel burns pretty hot! I am consider purchase any way because of the NIB condition....I may try to make a "restrictor plate" of sorts to tone down the stock Meths burner, or I could also source or make a Banjo style.
  I also hope to find an SP1 but this post is really to ask the forum if there is a smaller vintage type engine of any "brand" out there? -thank you!

The MM1 is the engine in the center:

The spirit used in these burners can be ‘toned’ down by adding a small percentage of water to make the flame less fierce; say 5% H2O added.

That "kitten" looks to be a real Treat, thank you for sharing Jim!
   Is the kitten a production engine? Or something built by a talented machinist?...I did a quick Google search and did not get any hits for any engines that look like this! -Ben

I don't know if it is smaller but an SEL Minor is really small and it is an undertype not overtype and shares a design for compactness.

This one is Charlie's.

I was able to find the Lilliput!
  I don't know Mamod very well yet, but I "think" that may be an MM2 behind the Lilliput for size comparison?
  Anyway, this one is certainly small!
Thanks for sharing Nick.

Edit:

 based on the width of "firehouse" I now believe the Mamod in photo IS a MM1 ....also it has the burner type that I like. That Lilliput is tiny!

That is an MM1 behind the Lilliput, yes, they are that small. I just realized I don’t have a video of mine on youtube, only the Jenny Wren…

Neat engines feller's, I have a soft spot for overtype  steam engines and these are some fun ones.

Thank you for this tip!...I believe this will work as my very first Stirling type engines I ran on "rubbing Alcohol" commonly found here in drug stores in the First Aid isle.
  During Covid the 91% grade was often sold out and I had to settle for 70% grade. I then learned to source 100% Alcohol used in sailboat cookstoves and was amazed at how Hot a 100% Alcohol fire could be!
  The Mamod Meths tray (rectangular burner) has a lot of surface area and the Alcohol with water content should tone down the fire nicely. Mamod MM1 engines on YouTube can often be seen walking around on smooth tables because of the huge fire!

Video: this gentleman has overfilled his Mamod Meths burner, he has to hold the base down to keep the engine from walking away, but is complaining of his fingers are uncomfortable holding the hot base! At times you can see the fire coming out of the door and also other parts of the firehouse!
  I know that Mamod Meths burners used properly work better than this. Enjoy the Video!

I found a Video of the Lilliput under Steam, What a Sweet little engine!

If anyone knows if these are still made? or contact info? I would greatly appreciate it. The gentleman in this video claims his Lilliput came in kit form.

Last contact I had with Phil Gravett was back in 2017 when he made my coin mounted engine. He had recently lost his mother at the time and I don’t know if he ever got back into building engines. You can try emailing him philgravett at hotmail.com

All of my engines from him (Lilliput, Jenny Wren, Beam, Marine and Coin) were fully built and ready to run.

Thank you Nick, I have politely reached out to Phil. I do not have high hopes but it would be cool if he still has parts for a Lilliput (the Wren is cool to)
   I felt it was definitely worth asking. -Ben

Ben the plans for the 'Kitten' is in Tubal Cain's steam engine plans book.

The 'Kitten' and the 'Polly' I think are the most popular made off his plans.

Thanks Jim. I was able to find steam books by Tubal Cain, they are highly reviewed and Also I was surprised to learn there was a Model Engineering class where students build a Polly engine....also found "Material kits" for Polly on ebay uk in about 6 versions! The different versions are things like with/without Cain book and if you want to build Meths burner or use Solid fuel tray or gel fuel.
   I have not heard back from Phil yet, I believe I will source a couple of Cain's books. None of the machine work scares me, I am hopeful the books will have advice on how to make a neat job of Soldering.
 
Video: I found this video of a Polly that is quite attractive to my eyes, the builder comments he changed the Polly plan quite a bit and it will require quite a bit of polish to keep his all Copper boiler looking this good!
