    Brian, I notice that you used a similar setup with the contact points as the Webster. I am thinking of doing the same thing and wondered if you found any problems with the change from the original plans? Also, I am having trouble getting the Chrysler contact points that I used with the...

    I have just finished machining the piston for a slide fit into the cylinder liner. I had originally intended to use Viton rings of which I have now received. The piston is still in the lathe ready for the grooves to be cut for the Viton rings. However, the slide fit of the cylinder onto to...

    John, Thanks for your help. Yes, that is basically the method I will use to make the crankshaft. Brian, has also used a similar method. I was originally going to make it as per the Kerzel plans but I was concerned of trying to keep it true on the lathe. Making the crankshaft by not silver...

    I have finished the main bearings in sintered bronze and the cylinder liner. All I have to do now is lap the cylinder to size. The Acro Laps arrived today so I can get started on that. The main bearings need to be machined to a fine finish but I will do that when I have finished the crankshaft...

    minh-thanh, that sounds like a good idea. However, I am going to go with the multiple piece crankshaft and see how that goes. I have already ordered the cold rolled steel. thanks John

    Ok, thanks Brian. I have decided to go with the multiple piece crankshaft.

    OK, what you say makes good sense. Do you think I could use Bright Mild Steel for the shafts instead of Cold Rolled Steel?

    Minh-thanh, What method did you use to join the pieces together. I have oxy gear but I am concerned about distorting the shaft.

    Brian, I am leaning towards multiple pieces as it concerns me of getting accuracy from one piece. How did you avoid distortion when you silver soldered the rods? John

    I am about to start the crankshaft. I notice that some people have made it as per the plans from 1 piece and others made it from multiple pieces. I notice that Brian made it from 1 piece and also made it up from steel rod. Any suggestions on the best method for this part? John

    Finished making the bearing caps today. I should of finished them earlier in the week, however, I got to the last part of the operation and cut on the wrong side. Frustrating as I had nearly finished them. It was a good lesson as I had been in the shop all day and was getting tired. I should of...

    Thanks for your input, I will have a look at your video on ring making. At this stage I will go for lapping the piston to the cylinder. However, I thought that when I machine the Piston I would cut some rings and have a try anyway. I have a lot to learn in model engineering and trying to keep it...

    Sounds good Brian, I thought it may be beneficial for little effort.

    John Builds Kerzel Hit & Miss

    Thanks Brian, I will order a .750 Acro lap from the US and use the method you suggested of lapping the bore and machining the piston to fit. I was also going to make the cylinder and piston in cast. If I turn the piston to the bore, do I still need to put some grooves in the piston for oil...
