Coehorn Mortar

[MAPMFF]

Around $800 for both of my coehorn tubes.

Finished cutting in the blocks for the coehorn tubes. Fun fact these two tubes are from LaPan, and are sequentially numbered!

I'm just waiting on the historically correct linseed oil paint to arrive, which should be here this weekend. I've never used it before, lays on the same as modern paint, just has a longer drying period. If it stinks too much to pain in the workshop it'll be put on hold until warmer weather where I can paint them outside.

Once that's complete I'll mount the hardware that my blacksmith is working on and they'll be ready to go.

Your wood base looks good! I don't care visually for a base made from modern cut dimensional lumber.

Agreed and I didn't want to have that as historically they were all hand sewn pieces. And for what they were they were relatively disposable pieces of equipment that wouldn't have been perfectly made, especially when seeking replacements while on campaign.

Auction mortar closed at $225.

Beds are primed. Decided to skip the modern home depot paint and went with the more historically appropriate linseed oil based paint. To mix up the primer it is 70% linseed oil and 30% paint, boy is it soupy (see the splatter on the flag ) and takes about a full week to dry.

Mortar beds are painted.

Tompions painted and in place. Tompions made by the talented @zulu

Just picked up the hardware from my local blacksmith, will be working to paint and install it this weekend. Nearly done!

Thanks man!

We're getting there!

Apologize for the tall photo on this one, was a post to our artillery units social media pages.

But happy to say started the hardware installation today, got interrupted by a few things and have a few days of work coming up so it'll have to wait a bit to finish, but so far so good.

Very cool- the hardware looks great.
I am wondering how these were adjusted for distance. Was there a wedge used under the tube or stuff used to prop up the base?
I have seen videos from the N-SSA of how accurate these simple things were!

Variations in powder charges and wedges were used to adjust the angle of the barrel.

Hardware is installed. It's been painted and is drying. Hopefully have these totally complete next week.

How great is that hand-forged chain?

 

[MAPMFF]

Well this project is complete!

 

[MAPMFF]

I chose to number the blocks, 4 & 5 even though these are the only two I have. Despite having purchased the tubes separately and one in Mass and one from way up in Maine they are sister Coehorns from the LaPan foundry. No's 34 & 35 ! Who knows how many years ago they were cast and separated by several hundred miles but got them back together, which I think is pretty cool.

While LaPan's tubes are not 100% historically accurate to what a real tube would look like, mainly in the cypher and some other small details they have a very close likeness. Combined with the two new historically correct blocks and hardware they look pretty darn good and should make good talking points at displays and be great for static firing demonstrations.

Onto the next project!

You've done a great job on those.
Been wondering if a baseball would fit!
