De Lisle update
Posted by Standard_Act7948@reddit | GunnitRust | View on Reddit | 10 comments
The De Lisle barrel is done aside from chambering and notching for the bolt head, that’ll come after the bolt is finished being shortened. The barrel has a lot going on and it’s interesting because the barrel sits back into the action to account for the shortened bolt. For the ports I went ahead and cut them at a 20 degree angle rearward and I think that’s the route I’m going to go with on ports going forward. Just for frame of reference this started as a 1.25” .45 barrel blank.

This is awesome! I have a Enfield mark III specifically for this but I haven't even begun to think about how I'm going to get the bolt done. I bought a 45 ACP barrel and magazine conversion but this is beautiful and historically accurate work. I really hope you document everything. I'm going to keep my project paused just to see how you do it.

The bolt is going to be a pain. It’s hardened and the threads used on the Enfield aren’t standard threads. I’m considering machining off the threads on the bolt head and sleeving/threading it so I don’t have to make an Enfield tap. I’ll just be glad when I have the bolt done.

Seems like re threading would be way if it's possible

Are you going off of a specific print for this or doing it on the fly?
It almost looks like you are using the rear cap as a barrel nut of sorts.

It’s a mix. Some stuff I have prints or at least specific measurements for but other stuff I’m just making the way I figured it went together. It’s a shouldered barrel and the threads in front of the shoulder are for a lock nut for the rear cap of the suppressor tube. The muzzle threads are for this weird blast diverter thing that goes on it.

Oh so the end cap is separate from the lock nut?
Standard_Act7948@reddit (OP)
Yeah, since the suppressor tube isn’t concentric to the barrel it’s easiest to use a lock nut to index it.

20 degrees off horizontal/perpendicular to the barrel I assume? Do you have to clear debris from the barrel in any special way due to the metal deforming as you drill it? You started with a 1.25” barrel? Did you weld the rest or do you mean 1.25” diameter stock?
I love your work btw.

Yeah 20 from perpendicular or 70 from bore axis. However you want to slice that pie. I use a new, sharp carbide endmill to drill the ports and I don’t usually end up with burrs forming in the bore. And yes I meant 1.25” OD stock.
