如何使油漆罐斯特林发动机Assembly Instructions (1)Make the Pressure ChamberThe finished pressure chamber will be 1 1/2” tall.??It will be made from the top and the bottom of the paint can. Remove the paint can lid and mark a line around the side that is exactly 5/8 down from the top.??Mark another line around the outside that is exactly 5/8” up from the bottom.??Cut carefully along this line.??Cut carefully so that you also preserve the center section of the can.??You are going to use the center section to cut some additional parts. I use a sheet metal nibbler to cut my paint cans.??I drill a small hole (about 1/4”) to start the cut, insert the nibbler, then work my way around the can. Use tin snips to cut the center band of the paint can.??Make a vertical cut parallel to the weld that is in the side of the can. Measure and cut a strip of metal from the bottom of the can that is exactly 1 3/16” tall.??This cut is parallel to the cut made when you removed the bottom of the can.??This piece of metal will be used to make the pressure chamber sidewall. The pressure chamber sidewall will be glued to the inside of the top and bottom can parts.??Use the high temp silicone glue for this.??Glue all three pieces together at the same time (top, side, and bottom).??Start by gluing the sidewall to the inside of the pressure chamber top.??(The top is the piece with the lid.)??Use enough silicone to get an air tight seal everywhere.??I used a small piece of metal (about 1/2” x 1 1/8”) to reinforce the seam in the sidewall.??Set this assembly aside until the glue is completely cured. Make a DisplacerThe displacer is cut from a piece of 3/16” thick foam core poster board.??Measure the opening of the paint can.??The displacer will have to fit into this opening, so it must be made a little smaller.??Use a compass to mark a circle on the poster board that is exactly 1/8” smaller in diameter than the opening of the paint can.??This will provide 1/16” clearance between the edge of the d
