Hi minh-thanh.
Not a lot happening at the moment although I have started the con rod. Very busy a month either side of Christmas at work for me and family fishing trips .
It's is also very hot this time of year in the garage at over 100 farenheit degrees yesterday but when the energy level...
I bought some 1214 steel to have another go at crankshaft making and this one I like. I will have to sand a little as the bearings are a bit of a tight press fit
at the moment. Hopefully It is the last crank I have to try make for this engine but I need the practice........

Thanks for those pictures on the ring making Ray.
I will definitely have a go at making them. Is the od the same as the cylinder bore and what should I be aiming for the id.
Cheers

As luck would have it a mate of mine had some 1' round cold rolled 1144 he bought from Amazon a couple of years ago and gave me what he had left a 7" length.
Milled it down flat and had another go.Cuts like butter. Problem with using the round is when I make the counter balance and fit them...
Thanks guys I'll get there eventually .If I need to make a dud or two to get a good one ...well and good It's the only way I will learn.
I will try some different metals .The key steel was ok to machine but felt very dry and for me did not finish very well.I used a parting tool to cut

Well I just had a go at making my first one piece crankshaft and stuffed it up.I went slightly undersized on the
long shaft and the bearing fit is too sloppy. I could rescue it by changing from metric bearings to imperial but I want to have another go.This time I will try some s1214 steel...
Your making some good progress Ray. I also when I get to it:rolleyes: am going to have a go at making the rings which I have never done .
I have been saving a little bit of cast iron I have left over from another job that I got from Germany for making some rings as it seems
a better quality...
I like your vice Brian ,makes me want to get one.
I have two but no tilt . A vertex 4" rotatable and a no name tool vice of the same size but opens a lot further and does not kick up like the vertex .Can be fiddly
to use.
