First off, Thanks Grant for posting the links, I didn't know that.

DoN, you asked about the trunnion. After I turned the barrel down, I
made a small collett to hold the flat section squarely in the mill, and
I reamed a 5/16 hole, and the pin is the same diameter, with a few prick
punches in the centre to hold it in securely. Also, the material was 2
in. Naval Brass round stock.

And Mark... Thankyou for the compliments. Much appreciated. The axle
began as 1 in. round 6061 aluminium. I turned both ends down to 5/16,
and the centre of the wheels reamed to the same. I then put the
aluminium on the mill and made them 1/2 in. square. The inside "hub" of
the wheel is 5/8, so I them made brass washers to the same diameter,
reamed 5/16, with a thickness of 1/8. Putting the wheel on the axle,
then the washer left 3/16 of aluminium sticking out, which I then put on
the arbor press (with my thinking, the softer 6061 would expand,
pressing the wheels on) It worked as planned, and then I buffed the
hell out of them. And thats about it.

Cheers all, Jason

Thanks Grant! Hello jmdoiron, that is awsome! *Details* please!?! How
did you fasten the wheels to the axle? Barrel composition, construction,
description? I cant decide if I like cannon2, or cannon4 better for
my wallpaper!!!! You rock!

It is easy to post the full link rather than forcing people to go

find this distasteful for some reason. I don't get it. Anyway:

Hello

I posted some pics of a Cannon I made to the Metalworking
dropbox. If you are interested, they are called Cannon1 - Cannon5



That looks like a very nice first project. One question occurs
to me. Are the trunions inserted in a cross-bore, or are they machined
in place form basic stock? (And did you start from a casting, or from
brass rod stock?)

Congratulations,
DoN.


P.S. I don't find Cannon1 in the Dropbox, just Cannon2.JPG through
Cannon5.JPG, plus Cannon.txt.txt
