I'm beginning to see a pattern here. It looks to me that the market for this complete bolt set could be, dare I say Great Britain with a little Down under on the side.
Do you think most of the #7s are not in America?

One other thing you need to think very carefully about DaveN is the actual shortened bolt too. The original long bolts are easy to obtain as is shortening them. What might be a bit more problematical is indexing the new internal 20 TPI (?) thread start point. This is important to give you the correct bolt head stop point or 'overturn' as we call it. If you don't get this part correct, the whole geometry of the bolt will be incorrect. Not impossible of course and most probably quite simple using a pre-set lathe with tap and a degree of thought!
Or better still, anyone out there have a whole load of No7 bolt bodies?
Thank you again Peter. I showed Him this thread as I find all this information very very interesting and miles (kilometers) over my head. Even said I'm actually starting to understand some of it. I know any info gained on this thread will be of great help to our mission to get complete bolts out there to those who want to see their rifles active again.
As an aside I am loving the thread on the compass !
Well the prototype is done and tested. performance was 100%. It was really great to fire the rifle No 7 Mk I . I now wait for the parts to be produced so I can help those who wish to complete their rifles. My plan is to sell the bolt heads as they are complete but my Machinist went and found him a job and so the ejector plate is on hold but will promise when complete to make sure those who buy the bolt heads get the first ones we make, unless they want to engineer their own. That's it for now. daven
wish i hadn't sold my incomplete No.7 a few years back now - dammit.
Call me silly but the novelty never wears off for me. It's the ONLY Lee Enfield trainer that's a repeater. A .22 No.4 that goes bang reliable five times as fast as you can work the bolt providing it's all fitted up correctly.
By the way, I have a Parker-Hiscock tube and mag which can also be considered a repeater. I should add that the No.7 is the only reliable repeater! The Parker-Hiscock is cool but.......
I hope that I'm not too late with this suggestion as to modifying the shortened bolt body with a view to getting the correct indexing of the bolthead thread BUT..............
I have been advised that if you start your thread cutting tap into the original bolt head thread THEN continue it down to the position of the 'new' shortened bolt head thread, it WILL be fully indexed when the bolt is machined down to length
This makes productioon enginering sense to me. If you send a shallow threaded tap down the original bolt, withdraw it, cut/machine to length then the correct depth of tap will start correctly AND INDEXED when it's entered. Simple........... Don't forget that the bolt is a TOUGH material and only hard at the locking shoulders
We will be providing the actual bolt heads with the number 1 on them. We have only,( and when I say only it was quite a job),engineered the small parts for the bolt heads.
1. Firing pin assembly
2. Primary extractor and pin
3. Secondary extractor and screw
Be advised we do not have a rifle with a .22 magazine insert so each round tested was inserted one at a time, but should work fine in complete rifle as the bolt head fits like factory.
The index may vary slightly as even in our bolt some are slightly short (1-2mm from 12 O- clock) some slightly long (same past 12 O-clock) and some dead on the money. So some minor adjustment may be in order.
You won't sell them here; they will be confiscated by Customs & Excise unless they come in to a dealer.Quote:
