IHP 35 - irritating rear sight problem solved
Posted: Fri Mar 20, 2015 9:40 am
Among the most irritating and intractable problems I faced with my IHP 35 from day one was the fact that it was shooting so low and so far to the left that full adjustment of the rear sight for highest elevation and windage was still no use. I had to settle for experimenting with 6-7 different pellet brands and find one that happened to be just OK - that brand just happened to shoot low and to the right compensating partially for my IHP 35's faulty sight.
I finally solved the problem as follows.
I raised the height of the entire rear sight by putting washers under the holding screws. This was not enough because the stupid damn spring loaded pin that the IHP has as part of the elevation mechanism kept slipping out of position. So I removed the offending pin and replaced it with a flat ended screw. That screw simply sits there - like the old pin. It is not screwed in position. The presence of the pin (or the screw I have used) is essential for the sight to be raised further because the elevation dial presses down on the screw (formerly pin) and pulls up the rear sight like a man pulling up his socks by pushing down his foot down into the sock. As regards the windgae adjustment, I simply loosened the screw holding the foresight and tilted it to a slight angle to correct the windage. I now see a slightly tilted front sight pillar when I shoot - but I don't care as long as it shoots straight.
Finally I can try a wider range of pellets with my IHP 35
