Default My MANN Project Progress Update (by vmfn542bob)

In May 2009 I purchased two Mann Accuracy Devices from the CMP.
Once I had them in my posession I began to do some research and planning the details on what I wanted to do with them.
My first priority was and remains, to preserve them as they were 'gifted to me' by the CMP.
Over the ensuing three years I have worked out a design with my only design tool being Adobe Photoshop Elements.
Only recently have I had the time to begin implimenting the design.
I am not a machinist by training but metal working has been a hobby of mine since I was twelve.
My design is still a long way from completion but it has matured enough now to share on this forum.
My last post relative to my own devices was included in a 2010 thread (see link below).
When you look at the photos below keep in mind that this is still a work in process.
My plan is to have the three support blocks I have made parkerized. (I made one block for each of my devices and one for practice.)
The design of a stock is still evolving but I envision it will be made of alluminum and wood.
The support tube is 2 inch diameter galvanized exhaust pipe purchased at my local Midas Muffler.
Very soon I hope to find the time to mill the vent slots in several tubes and flare the ends that will be secured in the support block.
Once I have completed the milling of the slots, flaring and polishing them, I will powder coat them SILVER.
Our Sun City Metal and Woodworking Clubs have vast resources that, except for parkerizing, permit me to do all the work myself. .

A plan to support the MANN Accuracy Device by the collar.
See Post #15 -

End boring the MANN Support Block

The two Folger coffee cans contain the metal shavings removed from boring the 3-step hole in three blocks. (I did not save the shavings removed from the twelve threaded, counter bored holes that hold the two pieces of this 'clam shell' together.) The block is made with two pieces of cold rolled steel each measuring 1.500" x 3.000" x 5.200". The combined weight of two pieces was about 12-1/2 pounds. The milling operation reduced the total weight of one block to about 9 pounds.

MANN Barrel Support Block Evolving

The MANN Accuracy Device, Support Block and Support Tube (unventilated ) assembly shown above weighs about 21 pounds.
