Thanks for the nice compliment Chuck. It certainly is amazing how quickly one improves when you are really interested in what you are doing.
 
Looks great Brian! Can't wait to see it all meshing and pulling!

I went downtown, did a bit of business, and got my spring haircut. (Hopefully that will hurry spring along!!!) I stopped in at my aluminum supplier and priced out 4" aluminum tube and 4" aluminum solid round. After I picked myself up off the floor I hurried home and looked in my "big scrap" cupboard.--And darned if I didn't find the perfect boiler in there!!! Of course, it doesn't look much like a boiler right now, but give me 20 minutes-----

Looking really good Brian runs great and sounds good nice work as always.

Ha!!!!! I knew there was a boiler in there!! Now all I need is a piece of aluminum to make a transition cone. It did take longer than 20 minutes, but then again, it was FREE. It stretches the capacity of my 10 x 18 lathe to work on a 4" pipe, so I may take it to one of the machine shops I do work for and have then do a quick bore to reduce the wall thickness a bit. Since this only has to look like a boiler, and will ultimately be painted flat black, I think this will do just fine.

Are you planning to get the cone out of solid stock on the lathe or are you going to roll it from sheet stock? Sheet would be in keeping with full size practice since it is mostly a weather shroud and is not part of the pressure vessel.

I'm going to whittle it from solid Jerry. I don't have any slip rolls, and having done a lot of automotive paint and bodywork over the years, I don't want to expend the effort to make a sheet metal part look "right".
 
Just finished reading through the thread and it was very enjoyable.
I got interested in this kind of engine from Jerry's thread and am looking forward to seeing more.
 
Great job on the engine Brian. It looks and sounds like a sweet runner. You might want to go back and re edit your video and take out the part where you state you are going to take a bit of a break since you immediately started work on the boiler. :big: :big: ;D Everyone of us can relate.... Why do those projects in the shop keep calling our names when we have so many other things to do?

Keep up the good work!!

Here we have a $30 lump of aluminum, 4" dia. x 4" long. Over the next 8 hours, during the impending blizzard and freezing rain, I am going to do my best to turn it into a beautifull transition piece for my faux donkey boiler. I have my auxiliary heater turned to HI, I have an oldies station on playing good rock and roll, and my good wife is off working earning some grocery money. Does it get any sweeter?

Brian,
The only thing that makes it any sweeter is realizing how sweet it is.
Wonderful build by the way.

Regards,
Maverick

Aaahhh, life is good...

Hi Brian,
Being as the boiler wont' be boiling water would it have been more cost effective, and lighter, to buy a piece of aluminum tubing. Speedy metals has 4.00 dia. x 4.00 for $3.80.

And pray tell, my friend---How do I turn that into a transition cone?
 
Better still, roll one from sheet - same way as a real one.
