What was it in a previous life

DVLA wheel clamp.

Been in the Bat Cave all day and making barrels again. Well, not strictly true, I have the barrel blanks and I am profiling and chambering them for quite a longish list of gun builds.
This is one I do as a special order, very lightweight carbon fibre pre-stressed AR-15 barrel in .22 rimfire for one of the practical shooting lads:





Thought I would show you how I set up for chambering. I use a "range rod" to get the centre line of the barrel true to the centre of the spindle. This is a rod with an accurately ground bush on one end, I have a selection of them for different calibres, the rod is held firmly in the tailstock and I take two measurements jiggling the barrel at both ends of the spindle:



I use two clocks, both tenths and I will accept half a thou but no more:



Usually takes me a good half hour before I am happy and ready to start to cut the chamber, sometimes longer and if I can't get it right I just stop, do something else and then come back to it later.

Carbon fibre barrels, didn't know they existed, how do they compare with use? I mean do they wear internally?

They are a stainless steel rifled lightweight tube inside a Carbon Fibre structure and a stainless end bushing to put the whole thing under tension. I spent a not inconsiderable amount of time working this out and they are very accurate and very light so especially handy for the Practical lads because of the whole weight issue. I usually marry them to a polymer upper.

Tactical?

Landing pad for very small helicopters?

These guys allegedly make the best Carbon barrels: https://christensenarms.com/products/ but by the time I have a barrel blank in my hands it is £700 at least plus three months to get it here. I decided to make my own.

Tactical?

Very, I will build it up tomorrow and take a pic.

Sorry should have been clearer. You write practical I said tactical
Interested to see it definitely.

Oh, that's where I put a plug hole in the wrong place, I thought you were referring to the 'slight' gap around the beam.

Perfectionism is for when I'm older and bored, can't see that happening.

give it a fortnight more of lockdown...

 

[Barking Mat]

It's a question of scale @bigegg so many other things to do.....

 

[Barking Mat]

@bigegg

Two weeks, I'm off for six weeks minimum, might scratch the surface. It's a bit surface, I'll just keep scratching....

And often poking things makes them worse
Il just touch. Oh bugger

Finished turned the wheels. They only just fit in the small lathe,so resorted to using a 40mm boring bar upside down and running the spindle in reverse to finish machine the outside diameter.

They came out well, nicely finished. Is that a Harrison 350?

It’s a new 600group Harrison/Colchester/ Fong Kong special.

Harrison/Colchester/ Fong Kong special

Made me smile. I remember the late, great, John Stephenson having a debate with someone who insisted that only a Colchester was good enough because they were "British made". Wasn't too happy when John pointed out they were now half steel half rice.

I have a 300 and I am now agonising over a 350. I need to go stand in a corner and face the wall for a while. I did notice the carriage wheel was on the right of the saddle in the American favored position rather than on the left. Although all the hot chips land on your hand I am much faster with the traditional layout of carriage left hand cross slide with my right.

just made a "key" for removing the filler valve from one of these blow torches on a pound coil for scale.

.. does this officially makes me a "key worker"

now I can go and do my proper job a a key worker and get the phone answered

in these serious times we do need to keep our sense of humour.

and if anyone has a way to get me the next 3 months of work on full pay can you let me know......

.....only kidding on that, Im doing what I need to do in the crisis that the country is in.

Hahaha. Not a bad bit of kit by today’s standards. Not that that says much!

Don’t worry, by the time you reach the age of perfectionism, your eyesights shot.
