Did the Cohorn Build thread get deleted?
« on: February 28, 2014, 07:25:18 AM »
About a few months ago someone made a great cohorn mortar and had detailed photographs of the handle jigs and photographed and explained  the process in great detail. I was counting on that thread for in the future and the future is now. Any help on how to find that thread? Who started it? Thanks.

I think you're referring to my Coehorn build which did get deleted. I still have all the pictures and descriptions, just no motivation to make a new thread and get all the formatting right. Poke around in this folder if you want to see the pictures.


----------------------------------


Last are the handles. I've been putting them off because I remember the ones on my little 1" bore Coehorn being an absolute pain to make. Anyway, I made a bending jig out of scrap material to get everything the same. Don't mind that extra hole, sometimes my uh... assistant... has trouble remembering which side of the number to mark when the tape measure is upside down.



Then I made the flat part of the handles. I tacked everything together in one big block and drilled the holes so I knew they were spaced the same. Then I cut the shape with a 4.5" angle grinder and smoothed the corners out on a bench grinder.



Next I made a jig to weld the pieces together. The bent piece slides up against the stop, and the flat pieces slip over the studs in the block of wood. I just held the ground against the handle and tacked everything in place.



Then I could really stick them on good.



Then cut off the excess and smooth it out with a grinder and files.

I think this was one of the threads and posts that were lost in the server hardware failure.  So far as I know, Matt is still looking into recovering the lost data but no idea when or if that will happen.
