Closed crankcase Hoglet V Twin
My last project a Closed Crankcase Hoglet. I have used aluminium for the build with steel liners in the cylinders.
Building the crankshaft was the most challenging and getting it to run true, I turned the crankpin down to 5/16 on each end and threaded it and pressed it into the 4''x 1/2 discs using lock nuts to secure it. The main bearings are screwed into the centre of the discs and then I turned them down to 10mmm as a unit .
The main bearings are single row roller bearings. I have used an O ring and a steel piston ring, it compression tests at 160 psi
after the usual first start difficulties I have got it to run reasonably smoothly.
As I am new to this site I hope this post is not inappropriate as this is the work I use my machines for .
I have a Qualos Junior 4 " Lathe and a Hercus 9A Lathe both Dc conversions My Mill is a Chinese bench top machine with all the usual failings
