In the shop today

[Bofobo]

Well i figure i need a spot for the projects that dont require a dedicated write up. Ill start with this modified quad/dirtbike front brake ... um ... mount, its for a volt meter on one of my motorbikes

 

[Bofobo]

Also today i faced up my BPC wheels but need to center the center holes and find a suitable axle.

I also made up the plug and mounted it in the lathe to see if i could turn this size of material and i can although the steady is to small to use

this will be welded as solid as i can manage on a roller i have yet to build

 

[Janger]

Fun project Mike.

 

[PeterT]

Is that some of the 4140 stock you guys got last year?
What does 'BPC' refer to?

never mind, I get it, saw your other post

 

[Johnwa]

There are some design requirements for BPC in section 10

Thickness at the breach is supposed to be at least 1 caliber.

Also are you planning on annealing after welding. I would think the weld area will be brittle otherwise.

Play safe

 

[Bofobo]

This appears to be a non legal document outlining requirements for battle reenactments. Not sure of the relevence.

Annealing sounds like a good enough reason to build the foundry expansion chamber i had planned though

 

[GrayTech]

Not sure welding is the best method for a breach plug. I would look into a threaded plug. It needs to be much thicker too.

here's a cannon and other stuff!

Can you import a cannon?

 

[Johnwa]

I believe cannons are treated as antiques even if they are reproductions. Same goes for flintlocks, but amuzzle loading percussion cap gun has to be an original. I don’t think there are any restrictions on importing antique guns but I’ve never did it.

 

[Johnwa]

There’s a black powder Brit army shoot in Bowden late June. It doesn’t appear that there will ba any cannon though.
I have made contact with a fellow from Medicine Hat that’s involved in Riel Rebellion re-enactment. They have a ½ scale 9 pounder that they shoot. So far they don’t have any schedule for 2018.

As this is my general shop thread, today i start a new lantern tool post. I need one to hold my smaller boring/threading bar. Now before anyone gets into suggesting i buy a QCTP .... im broke, and i like the lantern style (yes i have used QCTP) added bonus i already have a piece of metal i can use.

 

[Bofobo]

first a rough size round is cut so i can face in the lathe to dimension, i will also drill the post hole at this time before i square it up rough on the band saw so it will fit in my mill for final sizing

.... 30 minutes later i realize im hardly cutting and needed to add a few more shoes

 

[DPittman]

Keep the pictures of your project coming as it progresses! Is that 4140 you're cutting?

 

[Bofobo]

lines scribed, clearances checked and on we go

Yes it is some of my 4”od 4140

 

[Johnwa]

One of my first projects when I got my lathe was a Williams type holder, much like this one. It handles 3 different sizes of bars and works quite well.

 

[YYCHM]

Did someone mention BPC as in Black Powder Cannon? What caliber, how big we talking?

Member historicalarms has lots of experience with the big ones.

 

[Bofobo]

Quick moment of panic and disaster averted, facing first

and drilling with plenty of cutting fluid

 

[Bofobo]

That will do nicely, now i can scribe and slice

Im removing the first cut mark by offsetting the new marks
