      Righto guys, time to do something new here. After becoming a little bored with the motocross diorama and packing it all away in a box (and I will get it back out again later on), I needed something else to get me going again. I do have a bunch of other projects that have been previously pushed aside but they didnít get me excited when I looked at them.

      Since building the Clerget 9B a couple of years ago, which I thoroughly enjoyed, Iíve been keen to do another engine. Iíve only had this Williams Bros. kit sitting on the shelf since before Christmas and I keep looking at it with much interest, so I got it down and started checking it out again. Well this one did excite me, enough to make a start on it and now Iím having a great time. And being the same scale as the Clerget they can sit together on the display shelf.

      This can be the starting point= the box and the bits within it, plus a photo of a real engine from my folder of reference photos.

    Thanks Mike. Speeking of ships, I found some old photos the other day of an old sailling ship I built for a mate many years ago after he lost his thumb in an accident we had. He was so upset when he realised he couldn't do it. That was a terrific model to build and it was hard to hand over to him when finished, but he was thrilled and that made it really worthwhile. Yep, diversity is a wonderful thing.

    And Joe.. I suppose that when you build the ships, youll build a working a dry dock that works like you did for trucks in your garage scene..

    The instruction sheet is pretty simple, just one sheet of paper with the engine on one side and the wiring on the other. There are also written directions to go with the diagrams. The instructions make it look easy but Iím sure I can turn that into a time consuming process. I'll keep it nearby to refer to occasionally. Right, so Iíll start in the middle and work out from there.

    There are 7 main parts to make up the main body and then the cylinders and all the accessories are attached to that. The crank case is in 2 pieces and the intake manifold is in 2 pieces. You might be able to see in the photo how much flash Pratt & Whitney Wasp R-1340 1/8th is on the parts (actually the photo doesn't show it as bad as what I see on my bench). Lots of cleaning up, filing and sanding Pratt & Whitney Wasp R-1340 1/8th to do here. Oh wow, the parts donít fit together very well at all. A bit of work is needed here to make it go together the way it should.

    The intake manifold has now been cleaned up to a much better condition than when the two halves were first glued together. Now the body of the engine is starting to come together, and you can see in the third photo how Iím going to keep it in two sections for easier handling. The oil sump which hangs underneath has a bolt head molded in for a sump plug, but it doesnít look very good so Iíll be replacing it with a brass one that Iíve polished up.

    This part of the engine needs to be painted before any other pieces can be attached to it, so Iíll do that first and it can be drying while I move on to the cylinders. In all the reference photos Iíve collected there are a couple that, to me, stand out from the others. Their colours are brighter and more appealing, but thatís just a personal opinion. So Iíve tried to copy this blue/grey colour I like but now that the paint has dried it looks like too much blue, not enough grey. Thatís ok, itís close enough. The photos here show it to be a much brighter blue than it actually is.

    Hello,

    what a project, I'm excited. 1:8 can be much, can you tell me how big is the diameter of the motor?
    This report I follow very gladly.

    I think that blue is really going to look good. Nice cleanup on the parts too!

    Thankyou Marek. The diameter will be 160mm. The Clerget 9B is 130mm.

    Thankyou Mike. I'm used to seeing the blue and now I like it. Much more clean up to be done. This is the worst kit I've worked with.
    Bull dust, blowflies, & the outback. Heaven on earth!

    These cylinder halves donít fit together very well at all. The fins donít line up properly, the contact surfaces are uneven, and thereís [B]lots[/B] of flash Pratt & Whitney Wasp R-1340 1/8th everywhere. First thing is to file the contact surfaces smooth so all the halves will fit together properly and then clean up all the flash Pratt & Whitney Wasp R-1340 1/8th . This really shows up the miss-alignment of the fins. I glued all the cylinders together and then set to work with a root canal file I got from my dentist friend. Itís like a Ďrat tailí file thatís half the thickness of a pin. This allowed me to file across the joins and between the fins to get it all to line up and look smooth and continuous. It was a long slow process but it made such a big difference that it was worth the time invested. A coat of primer Pratt & Whitney Wasp R-1340 1/8th helps blend it all together. Oh no, I've still got 8 more to do.

    David, Engines are more fun to build from scratch at half the size. Here is a 7 cylinder Continental for a N2S Stearman I started. One of these days I will get around to finishing it.

    I have heard those kits were a little rough.
