    Hi All,
    Thought I might share this as I go, I always wanted to build a WWII Welrod pistol copy and now I have an original the journey has started. I decided for the initial one to build a cut-away version so you could see the guts of it. But being non firing version makes it simpler to make and no issues with heat treatment etc.

    No doubt this post will get moved even though this in not about the NFA item suppressed gun, more the manufacturing process....keep an eye out for updates as it progresses.

    First stage started the receiver.

    What are the original wipes made of? Have heard they last about 15 shots prior to replacement before making a non sealing hole in them and how hard is it to replace them. I know these are not high rates of fire weapons, so would think the low round count would be just fine for its intended purpose.

    With all the new makes of suppressors the wipe has all but been removed and this is understandable for high volume fire, but I have always found older models that used wipes are much quieter, certainly in that style of suppressor.

    I understand that the wipes were made of rubber, I can just about see some red rubber material looking down the bore but, as yet I have not been able to get the front end cap off.

    I ever do manage to get the cap off I think it is an easy job to pull out and replace them (there were three) mixed with steel washer type baffles. When new the gun came with new rubber wipes and a long hook to remover the baffle stack.

    Enfield, have you seen this site?

    http://www.timelapse.dk/welrod.php

    All KINDS of information. Eighteen metal baffles set a quarter inch apart. Three rubber washers. The baffles, obviously, have holes in them, the washers don't. Fifteen of the baffles have a hole just slightly larger than the bullet diameter. Three of them have half-inch holes. These three go on the muzzle-side of the three wipes. The bigger holes allow the rubber someplace to be pushed to by the bullet. I thought that was cool - never considered it.

    And since rebuilding one could be dangerous - put a small-holed washer where a big one should go could cause the bullet do deflect through the side of the can, or plug the barrel, causing a KABOOM on the next shot - they came up with a replaceable ready-made innards kit. Pull out the old one, drop in the new one, good to go.

    A bit more done, though as you would expect a long project, interrupted by customers ha ha

    Getting a bit more done on the Welrod copy, remember this will be a cut away display one only, just to work out the manufacturing processes and tools etc. so a dummy barrel in this one. Have to say I am pleased with how it is looking.

    Got a bit more done over the last few days, had to make a split mandrel to hold the bolt knob then slowly mill on the lugs and limit slot. Starts getting to the point you really don't want to stuff a part up when you have put a few hours into it ha ha.

    Ok Gents, time for another update, these latest parts have taken a bit of thinking about but, we got there.
    First I made a boring bar to cut the groove in the receiver for the bolt lugs, now the next bit to work out how to cut the slots to fit the lugs, decided initial mill then a broach to nip out the corners.
    So I made a holder to hold the broach then ground that to the correct rad, next I milled out the receiver for the lug slots (ignore the two extras at 9 and 3....even super heroes stuff up sometimes ha ha). So next how to lock up the mill to hold the broach, ended up making an Al clamp for the top of the spindle and bolt on parallels, so the quill could go up and down but not rotate.
    Next to try the broach and it worked a treat, small cuts but much easier than I thought it would be.
    I bit of a repair to fill the unwanted 9 and 3 cut outs and all looking good.
