Sows ear

[tel]

Yep, I had serious doubts about doing it that way as well, but it turned out fine.

Hi brian and Tel
I Think I pressed the cam onto the gear on my webster and with the gear hole being a touch oversize it seemed a natural way to go.
As it turned out I wanted to try the fit of my new gears before I made the cam ,hence one fast and easy brass bush ;D,
I have not looked at the pining yet and am not feeling so hot today so dont know if I will get into the shed till my headache goes away.

The vast majority of the inertia is carried in the rim of the wheel, not the spokes....it should be just fine.

Hi Dave
So it would be OK to thin down the other rim to match? (I guess I could press some outer rings on latter if they turn out too lite).
I braved the heat for about 5 Min's today and cut the glass tube for the liner oilier,I'm starting to feel a little better now so maybe ill turn the brass after its cooler

Coming along well Pete Thm:

Looks like you're on the Mythbusters team... There's a saying concerning a pig's ear and a silk purse; looks like you want to bust that one

Keven helped me with the Cap bolts without me knowing it (those wheels are such fun to turn ;D)
He did not move it much but ever since ive had to put up with one bolt thats just not right LOL

Another little piece to the puzzle

[Metal Butcher]

The lock out lever looks great!

That's one of the tougher pieces of the puzzle. Every time I looked at the drawing it gave me a head ache!

And I'll bet your glad its out of the way.

Hi MB
thanks for the visit
It turned out an enjoyable little piece to make and all I had to do really after drilling all the holes was connect the dots ;D
I still need to round off the end but I doubt that will be much trouble

Hi guys
Today I got the cam follower guide almost done (it still needs a small antifriction groove but I dont have a mill bit or collet that small yet).
I also roughed out the fuel Tank, which will double as the base, and be screwed onto a bit of varnished wood.

Now you're talking Pete, a built-in fuel tank just like full scale. That has been in the back of my mind for my still neglected project and am glad to see that someone else is pursuing that route. I've been following your progress with much anticipated interest and so far it is looking real good. Were you able to 'finnagle' that full scale engine from your friend? You know, offer to mow his lawn for life or something outrageous like that? :big:

Very, very clever with the gas tank in the base. I really like that.----Brian

Very, very clever with the gas tank in the base.

Just goes to show, your not just a pretty face. :bow: :bow:

Hi Jim
the tank is going to be interesting as it will have pressed in copper pipe for the carby outlet and depends on what I decide on, perhaps screwed in fuel filler. (some kind of elbow maybe)The tank vents just under the crank.
Don't know if I will go with a flip cap as in the "united" or a screw in.
My mate will not part with it so far but that motor needs a good going over before it starts to deterate.

Hi Brian
just making a few adjustments to the same good basic design to make sure the "Sows Ear" has my stamp on it. I really hope DK approves

I must admit Bob
I'm not very pretty either :big:
yesterday I got some offcuts in brass and Alli and so now I can power up this build
unfortunately, the Alli I'm using for the tank, machines like glue,I want to get some more done today but I think I will start with very very sharp tools for the tank.
