Easy mod for the slop... drill a hole with the barrel in place and tap it for a grub screw, be sure the grub screw has the little grippers on the bottom to grip the dimple you made in the barrel when drilling ;)
So, if you mess up on widening the port hole, couldn't you just cut it off, clean up the end and re-drill the hole again if you have a longer than stock barrel? 24" gives you a lot of material to work with.
Hey there! How far down Did you drill using the 11/64th drill....? Did you Need to smooth out the lead on breech end so Pellets aren't scored and O-ring seals correctly?
You are also missing a safety point. The original transfer port is machined steel for a reason, it acts as an anchor for the valve inside the tube. The only thing holding your valve in place now is that silly single screw.
you simply need to make a drill jig just take a piece of aluminum bench tools hacksaw yes hacksaw cut a block get the big mill bastard from home depot and for gods sake make it a high tension hacksaw starret or craftsman ect square it up use a scriber( look for a video called colonial gunsmith that's a guy who can use bench tools)remember interchangeable parts for fire arms is why we don't fly the british flag(sorry lads)use a center punch and a good combination square and the depth rod on the end of a dial caliper get the 2 for 25$ deal on ebay there good use feeler gauges or things of a know lengt to check acuracy lay out the 7/16 hole in the middle 90 deg the hole for the cross hole I think you see what im saying but definatly watch colonial gun smith yer gona love it I know!!! some basic knowledge of bench tools and you'll be much more prepared to work metal

The 11/64 is the smaller size so it goes all the way through. The 1/4" bit should go in about half as far. And yes, whenever drilling metal you'll need to deburr the hole. Rolled up sand paper works well for that.

Yes, but that is a lot of extra work.

Why not use a tap?
I can buy a brass tube transfer port from e-bay with a sealing sleeve that seals both barrel and action ends of the port. GB£5.00
Have you got clear nail varnish on
That's exactly what it is actually.

Maybe a Cone shaped rotary file with rounded tip , let's say 3/16" to about 1/4" going in breech end?
