Hi all,
I have just started on a project to make a 10 gauge shell black powder cannon like this one:
http://www.model-engine-plans.com/engineplans/images/1779.jpg
It is modeled on a nine pound naval cannon from a drawing I found online.
I have started turning the barrel to dimension and have a dilemma.
I am not sure whether the I should bore the barrel before turning the exterior to final dimensions or after.
At the moment I have the billet in a three jaw chuck and a live centre.
I plan to do the next phase between centers once a lathe dog I have bought arrives.
The brass is 2 1/2" in diameter and 14" long.
If I finish the exterior then I am not sure how to go about holding the piece for boring the centre and if I bore the barrel I will not be able to turn it between centers unless I guess make some bushes to fir the bore and centre drill them.
What is the best approach?
What is the best way to protect the work from clamping damage from the lathe dog and also get good contact?
Any advice would be welcome!
Here are some pictures of progress so far:
The 360 brass billet ready for turning
Ready for turning on my heavy ten with brand new steady rest from Tools4cheap
Chips starting to fly
The muzzle almost to final profile and a turning dilemma!
