Thanks for the compliments lads, Chuck, just to answer your comment. I get out there and do it when I can, I just might not feel up to it tomorrow.
Anyway, managed to get a bit done on the flywheels.
You can see on the first pic that I have marked them out to roughly what I want to achieve. There is a reason in my madness for choosing such diverse designs. The one on the left is being given to my friend who is the size of a gorilla, so I thought a nice heavyweight flywheel. The right hand one will have children playing with it, so I thought a much lighter flywheel, with no big places to stick fingers in, and if they did get their little digits in the engine somehow, it wouldn't hurt so much.
Three hours later, the basic flywheels are done, ready for boring and polishing.
When I talk about how long it takes me to do something, it isn't boasting, it is trying to show that these sort of things do take a fair amount of time to get done, even by someone with my experience. If you rush things like this, you get something that looks like it has been rushed. Take your time and things turn out a lot better. Do your planning beforehand and you won't be in for any surprises.
They have turned out just how I wanted, the left hand one looks definitely 50'/60's retro, and 'beefy' looking. The other has had an extra set of holes put in from my original concept. It also looks like a large version of a Meccano pulley, so the kids hopefully will relate to it.
All the work on these wheels was done on a RT with just one cutter, a 4.5mm three flute slot drill, and a notepad to write down the settings as I went from stage to stage, so each section is exactly the same. Also you need a big sign on the door of your shop with the words 'Do Not Disturb', it only takes one lapse of concentration and you will be doing an on the run redesign.
