Demon V8 (multiplied 1.5)

Looking at all the parts brings back good memories. At the larger scale of your build have you ever thought of trying to adapt an RC motor for electric start?

Beautiful work! I look forward to hearing the rumble as well!

Steve I second that feeling!

Foketry I have been setting on the side following along things are looking nice!

Hello Foketry, that looks amazing I like your style.
Do you have a blueprint for your V8, or are you design it yourself?
If so chapeau

I think of using this electric motor for scooter, hidden in the wooden base, transmission by small chain and free wheel, or to simplify , with a Bosch screwdriver

rocker arms glued on a wood base previously milled flat and parallel, to remove excess aluminum and avoid damaging the tool

Excellent work. Don't forget there is a relief cut on the bottom to clear the spring retainer. Now would be a good time to do that as well as counter bore for the screw. Great idea to glue down for machining.


Saw your next post, never mind.

yes, through the same jig mounted horizontally , I also did spring impression and screw counterbore , but I didn't take pictures
before doing this jig, I tried to make holes by fixing the rocker in the vice, but I only made scraps, the holes were off-center
I had to completely redo 3/4 pieces, I only had 2 spare parts.
my mistake for inexperience

After finishing the rocker arms, here are the other components of the rockers

This week I received the raw material for crankshaft

After doing the 4 centers at 90 degrees + the central center, I roughed out the whole drive shaft
