Hi I'm Bernard and live in area of Landes in France. I am retired now and among other hobbies I machine metal and build small 4 stroke engines. I started with a HQ 500 a multipurpose machine and now I have a lathe and a milling machine. I first made a rustic four cylinder and then a single cylinder, both working. I know, I should have done the opposite....and the learning curve was arduous. However, this did not discourage me and I have started to build a 72cc V8 of my own design. The technical difficulties are not lacking and I will be very happy to chat with all the members of the forum who wish to do so. Sorry for my broken English!

Can you post some pictures of your engine ?

Thank you for the welcome message. I have started a post for the V8 project.

Bernard,
Welcome to the group. I would also like to see photos of your engines and especially the rustic four cylinder.
Your English is good. Don't worry.

Welcome,
Good luck with your engine building.

Some pictures of my two previous realizations:
The four cylinder is of personal design. I didn't know anything about machining before I started it and I think I made all the mistakes I could in design and realization.... a kind of quick training. It simply turns.
The single cylinder is built on the basis of a Cad Jung design. It was less fun but more efficient....It runs now with unleaded gasoline and propeller. I did not measure the power but it produces a lot of wind!!

Bernard,
Thanks for posting your photos. I like the design or style of your four cylinder very much.

That's two nice engines.
Interested to see your 4cyl. crankshaft & connecting rods.
You live at a nice place. I've been visiting Arcachon and Isle d'Orleron a few years ago, that should be nearby. Won't forget the coastal patrol with Mirage 2000 at that time, they were flying fast and low all over the day.
Good luck with the V8.
I'm slowly proceeding with similar project, inspired from Schillings & Jung, but still nothing machined.
Kind greetings,
Christian

Thanks for your interest.
@ Roger:
Nice to meet you so far away from our places of life.... while we are almost neighbors.
@Christian
Glad to know that you appreciate my region. I can't find all my pictures of the 4 cylinders machining, for the moment. I just found these ones.
Connecting rodes are steel made with bronze rings
the crankshaft is one-piece and rotates on 2 bearings, the gear-driven camshaft can be seen below. It rotates in reverse to the crankshaft.
happy if it helps and successful continuation for your V8 project !
