Thanks Stan. I have some degree of mechanical skills and like to work on my own guns.

Well done. More guts than I have! I have lots of machines in my shop, including that same drill press which I only use for polishing and wood work. You would really enjoy having a good vertical mill.

I've worked on a Bridgeport for many years and yes that would be the right choice except it would not fit into my basement as to height. A few years ago I was thinking of buying a small mill from Grizzly but now I do not do as much as I used to. My shop is really set up for woodworking, but I do have a small Grizzly metal lathe that lets me make small projects. On my 20" drill press I bought a XY table and made a barrel wall thickness gage like the one that Glazan had. There are two rods one for 10-12 ga and the other for 16 ga., and I can get repeatable readings taking the barrels off and back on. As shown in the picture I can reach 16" into the barrel from breech up, but on a tight choke 12 ga. the muzzle end will not fit over the rod. (5/8" rod.625 plus half diameter of ball .0625

Great post, David. Your comment about the Bridgeport reminded me of an experience I had as a teenager working in a local instrument shop. I was working late, by myself, when a delivery person beat on the door. He had the Bridgeport vertical mill that we had ordered months earlier. The driver was alone, and not well versed in material handling. We had a narrow driveway and a high dock, about useless unless the truck had a side door, which this one didn't. We took about 45 minutes getting the truck situated so we could move the mill onto the dock. I took another 45 minutes accumulating broom sticks and steel stock, enough so we could roll the big machine into the shop, about 25 yards or better. Short story was that my boss couldn't figure out how the big Bridgeport got set in place the night before. I'm not sure I ever explained it to him.

Would you happen to have more pictures of how it is assembled? This is really neat!

Bill, great story on moving the Bridgeport. They are so top-heavy that the best way to move one was the way you did it. When I was working, our shop was getting remodeled and there was this massive Fosdick Radial Arm drill press that had to be moved. It was moved just as you described.
journeyman, what pictures would you like on the assembly? If the barrel wall measurements I didn't take any using the xy table on the big drill press. What I will tell you is even though the table is big it is only supported by the 4" column with a rank for up and down. Table is still shaky so I used two 2x4'a on each side of the table and lowered the table onto them and then locked the table to the column. This really helped in stabilizing it using the 3/4" drill chuck with a 1/4" ball end mill. I also had to mill out an area for the spring loaded arm that is tapered to accommodate the brass arm so that when compressed into the slot the rod that the barrel goes over has to measure .625 Also and the ball has to be right across from the spring.
Someone, not mentioning name, said that this type gage and the Hosford gage will not work because of flex. I can't believe that because if it did you would not be able to repeat your measurements within .001-002 reading in the same exact area.

When moving a mill, it is best to lower the table as much as possible and turn the head upside down. If a large machine starts to turn over, you can't stop it; run out of the way. Mike

You are 100% correct in your description of the amount of wood that is relieved for accomodating the HOT system on an L.C. Smith shotgun. Very nice project indeed, great close-up fotos, just wondering in today's market, how available are the parts required for such an endeavor?? RWTF
