Hi everybody This weekend saw the manufacture and installation of the quater rib and the rear sight. I used an express sight availible from Brownalls with one fixed and 1 folding leaf. It appeared not disimilar to others that I have seen on double guns and I am quite pleased with the result. I also constructed a device that I hope will allow me to simplfy the regulation. Now this is very much an experiment so I am covering myself if it dosent work!! The difficulty that I have is range time at ranges that are rated for this calibre of gun. They are few and far between and most are under the control of people that may not be entirly happy with the arrival of my blowtorch and workmate stand. The device can be viewed as a figure of 8 laid horisontal. The left hand ring is a solder fit to the LH barrel. I have welded the two sections together with sufficient space so that the RH ring has 2mm of clearence all around the RH barrel with both of the barrels boresighted to the same spot. I then drilled and tapped for 4 diagonally opposed set screws. I also fitted a tempoary front sight. I put all the set screws into their centre positions and slid the assembly onto the LH barrel and soldered it in place. The theory is this. I shoot and dial in the RH barrel to coincide with the left and lock the settings tight. I then take it back to the shop and make the perminent front sight a solder fit to both barrels and join them up. I then unsweat the device and then cut it off of the barrels. It is sacrificed but as it only took 1/2 an hour to make that is no great loss. If nothing moves ( and it shouldent) then I hope that it will not effect the regulation. Heres praying!!?? Regards |
