Thank you for you Eco Power Stirling Engine Kit order.

There is a corrected part in your kit. The Eco Power kit that you will receive was punched with a couple of holes that were too large.

The white punched sheet has the correct size holes. This will be obvious when you have the kit in hand.

To assemble the engine you can either use the white sheet. Or, you can overlay the white sheet on the colored sheet, and then cut out 1/2" of paper around the only two holes that are smaller on the white sheet than the printed sheet. Glue the cutouts carefully onto the printed sheet.

We recommend simply using the white sheet, but either approach will work.

Additional tips for building this engine:

  1. Scratch sand the thin aluminum plates with a coarse sandpaper (40 grit or so) before you glue to them.
  2. After that, clean the plates with rubbing alcohol, or a high alcohol content grain alcohol. Let the plates dry thoroughly before gluing. The plates come with some oil on them and this may cause the glue to fail if not cleaned properly.
  3. Consider gluing the bottom of the engine to the aluminum plates with a brand of epoxy called JB Weld. This is a gray colored high temperature epoxy that works very well for the bottom of the engine. If you decide to use an ordinary epoxy, a 30-minute epoxy will usually be stronger than a 5-minute epoxy, but it takes longer to dry.
  4. If your engine runs well at first, but then later does not, look for leaks along the bottom side of the engine.
  5. RTV silicone adhesive is a relatively high temperature adhesive, and works great to seal leaks on the bottom of the engine.
  6. You should glue the bottom plate on, only after you have already glued the "loop" cylinder into its circular position, and glued it to the top of the engine.

We appreciate your business. Please ask if you have any questions.
