    Mini lathe (and mill) discussion.

    It's a good time to have a look inside a 3W CS engine and see what changes are made. All the bypass ports are polished to a near knife edge, there is some polishing in the exhaust port and I was surprised to find a hemispherical combustion the camber. The pistons have a slight crown

    It looks bad but it is a great running engine. The mufflers were both skim cut to remove the exhaust port impression, the left muffler was fixtured in a piece of 1" x 2" x6" steel bar that serves as my 1/4" music wire bender. The spot faces were cleaned up and steel inserts were made that fit...

    Tomorrow I need to get the muffler cleaned up and fitted with inserts. I plan to skim cut the mounting face as well.

    Mini lathe (and mill) discussion.

    A friend bought an Aeroworks 100cc Extra with a 3W 150CS mounted on it, it's quite ballistic. When he got it home he discover the engine back plate had been welded, buyer beware. He had the plane out 4 or 5 times last year and every time the left muffler would come loose. He also found that...

    Inside the Roto 85FS

    The new head gaskets are somewhat convoluted as seen in the photo on the right and get compressed flat when the head bolts are torqued to 42 inch pounds. I had to borrow the old trusty Snap On dial torque wrench from my brother's auto repair. I'm pretty sure my dad purchase the wrench in the...

    Inside the Roto 85FS

    As stated there is about an hour on the engine. I was surprised at the carbon deposits on the cylinder head, the cylinder bore looked great however. Once the head is removed the pushrod sleeves can be removed. The sleeves are sealed with "O"rings on each end. I using Red Line racing oil...

    In order to remove the cylinder head 8 mm nuts, I had the turn down a socket to fit into the head, a twelve point socket may have worked but I don't own one.

    Inside the Roto 85FS

    The left side pushrod sleeve seals were leaking on the engine in my Champ, while the plane is down for refinishing I planned to replace the seals. I ordered a gasket set from Vogelsang Aeroscale some time ago. The cylinder head must be removed to accomplished this task. I have possibly an...

    Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

    Thanks Steven. I have the front half of the fuselage roughed in. This one is better than the first build because I learned from the first build. On the first build I glued the 1/16" aircraft plywood doublers onto the 1/4" stick frame before assembling the fuselage sides, I had one heck of time...

    Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

    I plan to use the first canopy that I pulled for the original Cherokee, this was too heavy to use and it will work just great here. I have the first side pulled off and started building the second side

    Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

    The photo below shows F5 and the rear most portion of the fuselage structure. You can see the difference of the original and what I plan to use. I plan to make the back half of the fuselage out of sheeted foam starting a F5 to the tail, all the lines represent how the hot wire will progress...

    Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

    So I have the Champ ready to paint and a friend from out of town is staying with us for the next few days, I don't want to do the paint work while she is here. Let's start another build then. I decided to start a new build and this will be focused on building the glass fuselage. Appowner and I...
