For those of you doing this conversion to a regular ML breech plug, I have found out some additional information. Had an email conversation with Lehigh Dave and asked him about the angle of the bottom surface of the vent liner. In that conversation he mentioned how important it was to have the proper angle to get the best seat and seal for the vent liner. I mentioned that I have been using a 3/8" bit, folloed by a counter sink to get some what close to the angle. He was nice enough then tell me that angle is 82* and then provided me with the information as to where to get the proper spot drill to get the work done. So I am passing it on to you all. Here is one of the bits you will need to make this conversion... www1.mscdirect.com/CGI/GSDRVSM?PACACHE=000000125969441Part Number: 00412320 I have made four of these conversion in the last few days but I am thinking I can get this spot drill and address my improper angle.

The Lehigh button head vents have a 82 degree taper, just like the savage vents, only the savage vents are Flat head socket screw, not a button head.

All machine flat head screws and the button head screws have a 82 degree included angle on the base of the head. They actually make cutters for each size screw that are designed to cut the proper dia and angle to seat these. I have several in my tool box for different size screws. I really want to get set up to do some machining in my garage. As a unemployed tool and die maker and the little jobs would help immensely around here.
