Lee endfield front sight wobble

Just a straight key slot isn't it? I had one apart a few days ago.

My idea was that the OP could just file a small flat on top of the barrel, taking care to make sure it is level and parallel to the backsight leaf. You do that by clamping the barreled action in soft jaws and putting a small level across the backisght leat and getting it set level in the vise. File your flat with a string level or whatever you've got laid on top of the file to keep it level.

Then file down the little straight key until with the key inserted into the slot in the inside of the foresight block, he can push the block onto the barrel such that the key is pressing firmly against the filed flat on the top of the barrel. It's either file and fit, file and fit or measure it up with outside and inside mics.

OP: if you're going to Loctite it you can use the same two level trick to get the sides of the foresight block at right angles to the backsight leaf before the glue sets.
Thanks for the information this is my first attempt at removing a front sight block
 
would take 5 min to set up in the milling machine and cut a new slot for the key way

JB weld up the barrel, 5 min in the lathe to clean it up and then on the milling machine and re-machine the slot. Reinstall the front sight base with the key and back on the mill to drill the crosspin.
 
Most people don't have that equipment in their shop or wherever they do their gunsmithing.

Taking it to a machinist or smith, looking at $150 and likely a 3-6 month wait.
 
We don't want to compare. Many of us here are lucky enough have nice shops.

Not everyone wants one though and many have other priorities which have to come first.

Then there are those that shouldn't be allowed to touch, let alone own tools or machine tools.

If I had a lathe and milling machine I’d never leave the shed, one day though
