Hi all; Thought I would share some pics of my current build, still very much in progress. Not a complete build log here. Just some shots of the various parts and a few setups. This is from prints by the late Jerry Howell. His family continues to operate the business, and they say all his products will be available just as they were before his passing. It's called a Duplex Vacuum engine, and is a Heinrici type beta engine. Not a vacuum engine at all, but named so because it was made in late 19th through early 20th century by the Duplex Vacuum Cleaner Co. All these parts are made from bar stock using the 618 Atlas and Taig manual milling machine. It still has quite a way to go. Displacer arm and a couple of the crank rods. The hot cap of stainless steel. Milling out the bearing supports on the R/T. And after much work with a Nicholson, nearly done. Boring the cylinder. And about finished but for the liner. Here's a mock up of the parts thus far. I have a few more things made. I'll put up pics of some more bits in a few days. Thank you for having a look! Dean |

Dean, You`ve made some beautiful parts there! :clap: :clap: I love all types of hot air engines. Looking forward to watching further progress...... :thumbup: David D |
| Bernd:
Nice looking parts Dean. :thumbup: Those bearing supports, super work. All manually made right? No CNC involved in those curves? :) Bernd |
| Dean W:
David and Bernd, thanks! Bernd, all manual machines, yes. I run a clean shop. No drugs, no CNC. :) Dean |
| Bernd:
I should have known better since I've been through your web site with a fine tooth comb and I didn't see one CNC. I think perhaps I had one of those senior moments. :lol: Many interesting projects there and much to get the mind working on using some of that info on my bigger machines. Bernd |
