Nice work! I have long been hoping some one would make a reproduction of the Lancaster! It's just too great of a design to disappear. Also, good job using NX for your software. I recognize those dialogs... I'm sure you are right in that they originally used a shaper to make that long narrow slot. You could do the same if you had a shaper head for a mill - like the one Bridgeport used to offer years ago. Walter Mueller describes how to make such a device in his little book 'building a single shot falling block rifle action' It might do for at least prototyping. As for your extractor indexing control, how about making the sides of the center pin flattened to ride in a bore of matching shape. Maybe you could get a big enough cutter to get deep enough in there to machine enough length to control the index of the extractor for it's full stroke? Or use a shaper head to make a fully square central "hole" for that rod to ride in. Check out the ejector rod on any modern double action revolver for ideas. Best of luck!!
Hey, thanks for the suggestions! That’s definitely something I’ll be looking into. I know enough to be dangerous, but there’s always more I could learn!
This was something I considered for a moment, but did not bother pursuing at this time. If I can keep the Extractor from spinning using the tolerance between it and the Lever Hook thingy then there should be no need for that complex feature. EMD machining would also drastically increase the time and cost of manufacturing as it would require a special tool to be made and shop that specializes in EMD machining. However, if my idea of tightening the tolerances proves to be unsuccessful, then other alternatives will have to be considered. Although, I would probably still try to go away from EMD machining due to the cost.
Without the slot, there will be a l more force and potentially wear on the side of the thingamajigger don't you think? Have you considered using a circular hole and a guide pin to replace the rectangular slot and groove?
Do not under any circumstance make a gun that they could rule illegal. They can and will prosecute. Send them drawings and other information on what you propose doing. Get their ruling on what you can do BEFORE you do it. Metford rifling does have a known history so the chances of a favorable ruling seem good. Barrel liners seem to be the best way to go. They are definitely legal and will not involve complicated machining.
After emailing the ATF quite extensively they said that they will not classify a firearm based on drawings, images, or anything other than a direct evaluation of the firearm. (I show that in this video as part of the email from the ATF). The whole classification process exists to help prevent firearm manufactures/sellers with new ideas from distributing illegal firearms as they have made the lines between what is legal and illegal quite blurry. You do not have to send a new firearm in and have the ATF classify it, but it is recommend if there is a chance they would rule it Illegal. If that is latter determine to be the case then the manufacture/seller would be responsible for buying back the sold firearms and having them properly sold via tax stamps/background checks or destroyed. Like I mentioned, if you send in a new firearm to the ATF that you are not legally able to own (say due to a lack of a Class 3 manufacturing license) then the firearm will be destroyed instead of being returned. For this reason, there are no repercussions against the manufacture as they followed the recommend procedure by the ATF of having the firearm sent in, evaluated, and then destroyed.
Nice presentation. I think I have an idea that might help with the extractor issue. Instead of making the body of the extractor rounded, I suggest making it hexagonal so that way the extractor won't rotate when the bullets shells are ejected. And also, once the Lancaster pistol reproduction is green-lit to mass-produce, do you plan on making a six barrel version of the gun?
Having the extractor shaft be hexagonal and using a hexagonal broach for the shaft in the barrel is a possibility. Also, I do not plan on making a 6 barrel version as it would fundamentally be a completely different firearm at that point. It would be way to heavy and bulky by that point, aside from having to completely redo all the internal workings to accommodate 2 more barrels. If you want a six barrel gun, the closest thing would be a pepper box revolver, but I can’t say I’m aware of any reproductions of those.
@@kurotetsuoni1315 Not to discredit him, but what is his brief overview of the pistol at an auction house (which also had some wrong info regarding the patents) going to contribute when I’ve done considerably more research on the firearm and it’s history, actually fired it, been probably the only person to disassembled one (multiple times) in the past century, and began reverse engineering aspects of the pistol he doesn’t even know about? It’s kinda like asking a game programmer to look at a UA-camr review of their game for tips on how to do the coding for the game.
You have ,I think, got the wrong idea on machining the extractor groove, this would have been broached, using a round tool that would be supported in the extractor housing, with a cutter mounted in the front edge, it would have been plunged into the hole ,(rather like the action of the Shaping machine, and the groove would be formed, another way this could be achieved would be by a carbon electro erosion process, all very normal machining practice. A wonderful series of videos by the way!! Chris B.
That is what was determined, but considering the depth of the groove, how narrow it was, how precise it has to be, the extra cost of having that feature machined into an already complicated barrel machining, and the need for a more complicated extractor part it was decided to try and eliminate this feature for our initial prototypes and try to use GD&T along with other aspects of the design to eliminate the need for this feature. This approach may prove unsuccessful, and doing a keyway broach may be the final direction that is taken, but only time and tests will tell the full story.

Extractor groove, consider Electro Discharge Machining.

@@AFWProductions I see
@@AFWProductions I highly recommend watching the Lancaster Howdah Pistol video by Forgotten Weapons for pointers that might help.

Yo I'll laugh if you see this but thanks for the outlast insane, claustrophobia run 🤣
You’re not the first to comment about those guides on my Lancaster vids 😂
@@AFWProductions I am very happy that you replied lol
@@snoopyfatdog1239 I don’t get enough activity on my channel these days to have an excuse for not replying 😅
@@AFWProductions you should do an outlast revisit or the new outlast trials when it comes out and do you have an xbox ?
@@snoopyfatdog1239 alas, my outlast days are behind me
First!
