ID:	1854577 I decided to start a new thread about my progress on the Radial 5. There's a couple photos on the "what did you machine today" thread. The cylinders are fit to the crankcase now, but I need to drill holes for the mounting bolts and exhaust ports. HSM ran a construction series by Rudy Kouhoupt beginning with the May/June 2003 issue.

    Nice polished work on something so small - will be neat to hear it run :-)

        Looks very nice.
        Also nice to see another build log on something.
        Keep us up to date.

            Is it going to be a regular IC engine, or run on air?

            Looks beautiful so far! Nice workmanship!

              wow, looking forward to the updates! From what I've seen of radials, the simple stuff is on the outside

                Yep, that's darn fine looking. And good encouragement for us to make something that runs.

                So.... any chance of this being a warmup for a running scale model of a P&W Wasp Major?

                  Thanks for the replies. This is a air engine. 2 cycle, with a rotary supply valve and exhaust ports near the bottom of the cylinders.

                  This is is an exercise in fit and finish. I'll move on to IC engines soon. Ya gotta crawl before you walk, and walk before you run, no?

                    I'm with you on the crawl, walk and THEN run. I've done a lot of bits and bobs for the lathe and other hobbies. And in a short while I want to start on a single cylinder steam engine. Then another and another and....

                      When you have finished that one, think of a seven, or a nine, or an eighteen.

ID:	1855074 Well, I drilled and tapped the cylinder and cylinder head attachment holes. So far, I've threaded 61,
                        2-56 holes. I think I've got about 20 more to do. I am short some screws and need to order a box.

                        Here's a couple photos of my fixture for keeping the holes at the proper angle. All the locations for hardware have been located by coordinates, so all the parts are interchangeable and fit anyway you want to orient them. This way I can hide the ugly spots as needed!!

                              Someday I'll figure out what I'm doing with posting photos in the proper order and placing the text where I want it. Don't hold your breath!
