jonesies popcorn designed by stew

[jonesie]

here is the start of my popcorn engine designed  by stew. also thanks to brian for mock up. the flywheel l i think  turned  out real good. took some time to bend spokes . need to  put radius on cylinder and crosshead. tough stuff done so now should go fast

looking good 

Did you silver solder the fly wheel ?

I particularly like the look of it, spokes look to be more of a curve than mine.

jonesie, it's looking fantastic good, but I have to ask you please don't load up picture that size, it's very hard to have a good look.

stew i silver soldered the spokes in the center hub, them turned the o.d. to a light  press and used 620 locktite into the bore.had to make the spokes twice as i had trouble getting them to solder, opened the holes up .003 and then pickled it all for a couple of days in vinegar . then used a larger tip to get the right heat, second time a charm. hope to get more done this week, need to cut the radius on the two parts.i also need to get some fire brick to help in silver soldering.jonesie

You can use thermalite blocks they are a lot cheaper than fire bricks, and you can cut them to shape with a saw.

thanks for the advice stew, i will have to look up a supplier over here.just need that little extra to help with the heat. jonesie

You can get the termalite from building supliers, over her in the UK, B & Q is the place, they sell off damaged blocks for 25% or less of full price, if they don't have any damaged, you can always have an accident with a shopping trolly.
