Look forward to seeing more of this one.... Well done.... Regards Alan Hi guys, thanks for looking in and your comments, always appreciated. Alan, you would actually be surprised at the tolerances allowed. Being wood, i guess it can flex a little Next, it is time to build up the inlet and exhaust valves. 8 dowels are cut in half, and then to length. The valve heads are numbered 18 and 19 (they call them K1 and K2 respectively). Care must be taken not to mix them up, as, like in a real engine, they are 2 different sizes. The ends of the valve stems are them sanded to a taper. Following the build sequence in the instructions, they are inserted into the relevant ports, and pushed home into the cam followers built earlier. The sequence for each cylinder head is the same: k2,k1,k1,k2,k2,k1,k1,k2, A bit of candle wax here helps with insertion into the ports and cam followers. Check free rotation, and watch the pistons rise and fall, along with each valve opening and closing, it absolutely amazing  CaptnBirdseye attached the following image(s):

That`s neat engineering in wood and at that scale its amazing. Looking forward to more of this. Regards delboy271155 (Derek) COME BACK GUY FAWKES "YOUR COUNTRY NEEDS YOU"

Del, Al, thanks for looking in and your comments. I hope you are enjoying this build as much as i am The next stage is setting the rubber bands into the engine. It's a convoluted process, but following the instructions is achievable. The end result is shown in the photo below.The next stage is to make up the planet wheels and pinions. Use plenty of wax on ANY moving part! The pinions are inserted int the correct end of the block, followed by the planet wheel, and another cog. The whole assembly is then held in place with 3 pins. I found it easier to clamp the ends of the block to stop the whole thing falling apart while trying to fit these bands! A second pinion, spacer & cog is then pinned through the other side of the block in the same manner. repeat the process for the other side. This completes the rubber band installation. Two tips learnt? Firstly, use plenty of wax on the moving parts, and secondly clamp the engine (drawback of not using any glue, until it sits in the chassis it moves around alot!)

Holy cow, the pistons and the intake:exhaust valves work too? That’s just crazy.

Certainly a very interesting concept and a cool looking model Gray, nice work so far. 
I knew a guy years ago who tried to build a full size car entirely out of wood. It had wooden wheels, wooden body, wooden seats and even a wooden engine. Trouble is when he tried to start it .... it wooden go!!

It's a fascinating build
Have they designed an access hatch to be able to replace the rubber bands?

Hi Alan, Mark, thanks for looking in and your comments. It's been an enjoyable build for me too . Ok guys, it's admission time  . Whilst checking the engine, i noticed i had fitted the camshaft facing the wrong way!  Now i must admit, there has been times when building this engine that i thought a bit of glue wouldn't go amiss!!! However, due to the dry nature and interference fit of the component parts, i was sure glad no gluing was involved. Something i had viewed as a minor negative turned out to be a massive positive! So, an hour later, engine dis-assembled, camshaft correctly fitted, and engine rebuilt. Result? 1 happy bunny Next comes fitting the chassis and steering gear. This is actually what stiffens the whole engine build up and begins to tie everything together. This completes the engine and chassis installation. CaptnBirdseye attached the following image(s):
