Author Topic: Finished! 1/2 scale Mountain Howitzer (Read 3521 times)

Here are some pictures of my 1/2 scale mountain howitzer.
The project took about 6 months to complete. I need to fab the ram rod, worm, swab and ball mould before I can fire it.
The bore is 2" (underscale) and the wheels are 24" (overscale) but all other components are made to scale from prints obtained from
Antique Ordnance.
I'm considering a matching limber for my next project.

Nice job!Always thought it would be fun to get a big piece of brass and make a howitzer,you will have fun keeping it clean.

Beautiful gun Steve! I'm curious, how many parts did you make yourself? The thing that would seem hard to me is making the wheels for a non woodworker.

Michael,
The wheels I didn't make. They were purchased from Hansen's Wagon Works in South Dakota. They are well made and are reproductions of cannon wheels but are 24" in dia. The actual wheels on a mountain howitzer were 42" so to be correct at 1/2 scale they should be 21" in dia. They sell for $175 ea. an are worth every penny!

Any reason for not half scaling the bore?

Blaster Bob will be along soon to remind you about PC

I bored the barrel with a boring bar. The reason they call it a "bore"ing bar is that each cut took about 15 min. I just got tired of machining it and I had a good finish at 2"
What is "PC"??

The wheels look great, as does the rest of it. How big is your lathe?

A very nice job, well done. Of course you'll have to do the limber now!

Aw yes boring bar, akin to watching paint dry only just a little more exciting, but only just!

Yes PC is Powder Can. Some time back Blaster Bob pointed out if you included a Powder Can in you picture it gave some scale to the gun. We have another post that is asking how to attach trunnions to a brass barrel. Care to share how you did it?

CU & DD

Well the truth is out!! The barrel is STEEL. I welded the trunions on as well as the cascabel and then had it brass plated along with the elevating screw. Cost of plating-$65.00

Excellent work on both tube and carriage, I wish it was mine. Steve, in the one picture the vent hole looks large; or is that just due to a shadow in the photo?

I made a spring loaded firing device that wasn't screwed into the hole when the picture was taken. It uses a musket cap that is fired by pulling a lanyard.

I hear the boring part. It took 12+ hours to bore my 12pdr from 2” to 4.62”.

Did you do all the iron work or did you find someone to help? Building 1/2 scale napoleon myself, looking for help on iron work. Gary

GAWI,
Did everything but the wheels.
Got to shoot is about six times this weekend to open the Arizona State BPCR Silhouette Matches.
Used 430 grains of misc. leftover powder with paper wads. Alot of smoke and a big mess from the confetti!!!
