Hey CU Cannon

What are the dimensions to your soda can mortar's union bed? Are they to scale?

      I bought the steel tube, Union style, Coehorn Mortar that CU Cannon built about three years ago and fired it last in Montana two weeks ago.  I just measured a few of it’s dimensions tonight.  Hopefully someone with a drawing can figure out if this good looking mortar is built to scale and what scale.

Yahoo shut down geocities a while ago, but here's a mirror of CU_Cannon's website. I'm pretty sure this page is the mortar seacoastartillery has: http://www.geocities.ws/cu_cannon/golf-ball-coehorn/golf-ball-coehorn.html


I saved a bunch of his plans he made before geocities shut down, but I'd rather not post them without his permission. I have mortar plans with a bore of 4.62" and one at 2.625".

     Jeff,  I don't think it's the same one shown in the mirror site.  I measured the Largest tube O.D. at 4.470" and the 'Mirror site has it at 3.875" O.D. and the length is too short to get 9.25" O.A.L. with the addition of a 1.50" dia. Trunnion.  Sure looks VERY similar, but the numbers don't add up.

     Rusty wants someone with an official drawing to relate my numbers to it and see if the bed is to some particular scale.

 Armorer 77 I am thinking about building another bed for the tube you made me for display,  nothing wrong with the one you sent me which was a surprise cause I thought I was just getting the tube.

CU Cannon has not been active on this forum since Sept. 2010. I remember being on his site before and would like to see his plans again. Here is a quote from him in Feb. 2005.

I have had several requests for my plans so here they are.  They are in pdf format so they can be scaled up or down without distortion and they print to scale.  If anyone wants it in autocad format let me know.  I will post some drawings of my base once I get it done. 

http://www.geocities.com/jeanluc83/cannon/Golf-Ball-Coehorn.pdf

Do what ever you want with the plans.  Make copies give them to your friends as long as you don't directly sell the plans it doesn't bother me any.  The only thing I ask is if you build a mortar from my plans send me a picture of it or post one on the board.

Thanks Double D and The Jeff. I need to learn to do it right I guess.
Does anyone remember if he had Handgonne plans. I had some and all CU Cannon plans but through a couple formats and new computers I lost them.

Does anyone know what became of Cu_Cannon?  He hasn't visited here in over a year and that is ominous.
