Awesome, thanks for all of the great pics. I feel I am right there in the shop.

You have a very sharp eye, Jasonb. I cut the chamfers at the top of the crankcase too deep and as a result the cylinder flange hangs over the edges. I did as you suggested and machined a flat to hide the error. Below I am checking to see if I hit the proper width between the two machined...

Boy another hot day in the machine shop, but I am not going to even go into it as Terry Mayhugh has the record workshop temps record all sewn up. I am working on the crankcase assembly, specifically the cylinder. I load up a round of aluminum in the lathe, face the end and use progressively...

Continued work on the Front Crankcase for the Lynx15. I parted off the the work piece after completing the lathe work on the inside and outside. I loaded it back into the lathe reversing ends using a 4 jaw chuck. I used an indicator on the flange right next to the chuck jaws to center the work...

I attempted to use an Arduiuo to control the timing advance of my model engine and could never get it working. the Electromagnetic Interference from the ingition system always (eventually) killed the micro controller. I went from a CDI to a TCI (transistor controlled ignition) which was...

I’ve been looking for a simpler engine to build and I came across Malcolm Stride’s Lynx, a 4-stroke air cooled engine that uses a timing belt instead of gears to turn the camshaft. So I started noodling around with a CAD model with the intention of building my own version. I am looking to...

Hi, I will be traveling to New Zealand soon and as our hobby has adherents from all over the world, I was wondering if anyone could make recommendations of places I should make sure I see, or make sure I avoid. Quirky museums that an old machinist would appreciate? I will be spending several...

Nicely done. I like to see how you are experimenting with ways to streamline the machining process when many copies of a part are required. "Mass production" really helps to produce a set of parts that are equivalent and not too time consuming.

I used a razor blade on one side as a shim to square mine up.

I needed some hose barbs:

Interesting technique to minimize waste when producing so many cylinder sleeves, Bravo.

I got a little help from Ellie in this installment of the Wallaby Build Series. There has been so much hype about AI, that I thought I would check out some of the tools available.

Why be Scared of Making Cams? These videos show how I made the Camshaft for the Wallaby 30cc Engine:

This is how I make the crankshaft for the Wallaby 30cc Engine.

Lantain1982, You have a great beginning on your 30cc Wallaby. I would like to see more pictures and follow your build log. What would you think about starting your own build thread? I will be an avid watcher.
