Thanks to inspiration from Cowgirl, I picked up the parts for a fatty piston at the hardware store today. Items included: a 12" long piece of ABS 2" pipe (apparently, ABS is OK for food contact), a 12" long threaded 3/4" PVC nipple, a 3/4" slip cap, a 3/4" male pipe threaded plug, and a 1 1/4" to 3/4" bushing.



I threaded the nipple onto the bushing; this took a bit of effort as the threads were tight inside the bushing. I ended up using a hair dryer to expand the plastic a bit in order to start the threads. I threaded it about 3/4 into the bushing threads to leave room to thread the plug into the other side. Then I screwed the plug into the other end of the bushing.



I cut the unnecessary portion of the plug off with a hack saw and sanded the plunger/piston surface smooth on my belt sander.



I then glued the cap onto the other end of the nipple to make compressing fatties easier on my hand. I then cut the 2" ABS pipe to a 9" length. Here is the finished product. Total cost: $4.40. Total time: 15 min. including pix.



I figured I would wrap the plunger end with a sandwich bag to make clean up easier -- may or may not be necessary.



I'll be making fatties later this week; I'll let y'all know how it works out. Thanks for looking! And thanks Cowgirl!

It always goes to show you that necessity is the mother on invention. Now I haven't seen one like yours but if it works run with it my friend. Now this is fine and dandy we want the Fattie Now.
 
James that looks great! Nice job.

I've been hiding out for the winter so maybe I missed it, but what does the fatty piston do exactly?

(I couldn't log on here this winter, people in nice climates smoking meat made me too jealous)
