    Antares 2cc - model diesel engine build

    Olli, It is looking very good so far. As far as the cooling fins go, you do what you have to, it's all a learning curve. With the bore, I aim for 1 thou between the bottom of the cylinder and the exhaust ports, and 0.0001 between the exhaust port and the top of the cylinder. I picked up a bore...

    A great looking engine, as above, piston fit is needed to be a very neat fit, the contra piston needs the same attention, except, it needs to be a tighter fit. Hope you don't give up on it. Cheers Andrew

    Terry, I hope you recover fine, I broke my back(L4,L5) in the early 80's so I know what a bad back is like. The engine can wait, get your self healthy first. Cheers Andrew

    Grasshopper, You should have been using a 0.374 reamer, the hole needs to be smaller than the shaft. Cheers Andrew

    Olli-Matti, Yes I done this in the time posted, I'm retired so have plenty of time, and apart from the piston fit, and that went quicker than I thought, it is just straight machining. Cheers Andrew

    Hi All, Well after a little bit of playing around, "IT'S ALIVE", After about 20mins of runtime now it's swinging a 9x6wide blade with no problems. Now on to the other engine. Cheers Andrew

    Gail, I have found this with the cheaper grades of cast iron bar. Never had the problem with higher grades. you can tell the difference by the sound of the cuts, the cheaper grade starts out hard on tooling and is like machining alloy in the center, the better quality is the same right through...

    Hi All, Up until now I have been making the parts for two engines. Now I will be working on just one engine at a time. Started the most exacting part of the build. Started with lapping the cylinder, very messy part of the build. Then machined and fitted the contra piston to the cylinder...

    Hi All, PROBLEM:- Getting small diameter cast iron round bar. FIX:- Make your own. I have some 40mm(1.575") round bar, cut length off of it, I have a 1mm(0.040") slitting saw, cut the round bar into quarters. Pieces almost triangular, fit into 3 jaw and machine round. Now have a piece...
