    Default Electric turbo & more

    Answering a few questions:

    1) I looked at the electric turbo right until the price tag appeared, then, thought about building one myself. Not knowing if the engine would even run, I opted for the leaf blower option.

    2) The Merlin/Allison blade & fork rods run on a common crank pin; nice pics - thanks. If money were no object, I'd have built a custom crankshaft and used a true blade & fork to keep the cylinders directly opposed.

    3) The design I'm using is very similar to a radial engine master and link. For those not familiar, the radial engine has only one crank pin. The "master" rod rides on the single pin; "link" rods are connected to the master.

    4) Unfortunately, there is no room for a conventional radial master- link design. The custom pieces are identified as "blade" and "fork" for convenience only.

    Yes sorry I forget that I don't worry about the cost of things because our customers have deep pockets.

    If/when the concept is proven, a more robust design might be built.

    Nice pics of the corn cob! Are the Merlin and R-4360 your pieces?

    My pictures but not my engines, guess we were just interested in the same way of doing things. If anybody is ever in Munich the Deutsch museum has a fantastic collection of cutaways. I've learned when designing engines you can learn a lot from the past. Trying to convince people to buy something new or revolutionary is almost impossible.

    Default Critical infrastructure

    It's been hectic lately, and progress has been slow. Critical parts acquisition includes a Merc 1000 flywheel with 9-1/2" ring gear from Steve Wheeler, and a Merc 500 starter motor from Doug Kay. You may notice the BRF demonstrating bugs again entering text right to left, so it's unlikely images will upload. If not, you'll soon see the starter motor and flywheel fitted. Work will be slow during the Christmas period, but next will be the rods.

    Default Hose clamps

    The hose clamp is an excellent fixturing device that enabled easy bracket mockup. Once the spanner is welded, a cross bolted support will be added to the starters inner bottom stud. The clamp will likely remain to provide additional clamping. Oh yeah; it's very convenient there's an extra set of fuel pump pads....
