9 ) The fitting of the displacer rod and the corresponding bearing is critical; make sure they are smooth and straigth. The goal is to get them as air tight as possible, while keeping the friction to a minimum. The same applies to the power piston and the corresponding cilinder. Never lubricate these parts. ) Join these parts with Loctite and wipe off any residue. ) This part of the assembly must be able to be taken apart, therefore a light pressfit is recommended. 4) As these pieces are likely to get hotter then Loctite resists, soldering is used. 5) Make pins from a staight piece of brass rod, lenght corresponding with joining parts. Use a very small drop of Loctite on one end to lock the pin in place, but keep the parts moving freely. The crank spacer is placed over the crank rod, against the crank If the glass testtube is somewhat different in dimensions, adjust the design of the cilinder holding the testtube and the of the displacer. The main concern schould be the air tight seal of the O rings around the test tube. Also make sure the displacer does not come in contact with any of the parts. To assemble the testtube in the cilinder, put all parts including the O rings in place and insert a very thin sheet of metal inside the cilinder. Now gently press the testtube inside, while making sure the sheet metal is between the O rings and the testtube. This way the O rings are compressed into place and friction between the O rings and the cilinder is low. After complete insertion of the testtube, gently remove the sheet metal. Ajust the hight of the candle flame by rotating the candle holder. The tip of the flame should be mm clear of the testtube. Apply a small amount of light machine oil or WD40 on moving parts, except for the displacer rod and power piston. Use open, degreased and cleaned ball bearings for the main shaft, 0x4x4.
