About this time it was apparent I would need a front sight so A Lee Enfield military sight looked like it would do the job with a little work

The part I couldn't do myself was to open up the inside of the band. I don't have a lathe (or a mill) so it was down to the local garage where he has a small lathe and he opened it up for me.
The locating lug recess's were almost completely removed so there was no visible remainder when I tapped it onto the barrel.
I went and fired a few shots and with the aperture sight at the lowest setting where I wanted it to be, the shots hit 22 1/2 inches low at 50 yds. With a 31in sighting radius, I needed to lower the front sight by .3875 and if I filed the ramp down and cut a new dovetail that would have cut through the hole at the top of the band that was there for locating purposes, and would have dramatically weakened the hold on the divetail. This led me to file the ramp down and split it lengthwise deep enough to take a blade I made from a piece of .125 thick steel. (just a square I cut from a piece of 3x2 box steel) The blades for the LE sights are only .05 thick and my eyes can not see them clearly enough as they fuzz up badly but I have found that the thicker blade is a usable sight and I have split more of these blades and fit them over the thin blades on some of my other open sighted rifles.
The sight was over about .785 from the band to the top of the blade as the LE offering and when I got it "sorted" with the new blade so it would print on aim it was down to .306

I did start with plenty of blade height

This will do
