silver bullet again

[stevehuckss396]

Steve, I used the Bob Shores "small gas engine carburetor" drwg SC-1 dated 4/25/02 ( same as the MINIMAX but a tad larger) Thanks for the suggestion

I am building the radiator by expanding your method shown on the radiator thread, pics forthcoming.

Glad all went well with the carb. I just built another radiator for the small V8. Method worked again. Looking forward to seeing your radiator.

Now I got some better aluminum sheet material, and sandwiched it between thicker stuff as you did. I also used mucho aluminum lube, and a sharp end mill. Guess what, it works beautifully. Now I can stop goofing around and get that pesky fan behind me. Lessons learned by newbie.

Mosey;

What is aluminum lube?

Ray M

 

[Mosey]

TapMagic for Aluminum. It increases the cutting speed 2-3x, reduces heat, and generally aids the machining. Very good stuff for me.

Tubes cut and spacers rady to assemble. The spacers (next size larger telescopic tube) allow the assembly to be soldered only at tube penetrations inside tanks.

Beautiful job building your engine!

I love the hand crank. Does it utilize a one-way bearing?

 

[el gringo]

yes KB, a roller clutch from SPDI

Very nice job on the radiator. And the entire engine for that matter. Any video of it running?

I love the way you have used the old time hand crank along with the one way bearing. Definitely give it that old look right off the bat. The radiator also adds class to the whole display. Yes, I did notice that there is also an engine in there and it is also a fine specimen. Nice work Ray and thanks for showing it to us. :bow:

Cheers
