Hey rod.
Found this on rimfire central.
Just about everything you need to know about brno’s is on that forum if you have a week to read it all.

Chappo,

Many thanks; that gives me a few more ideas.

I'll have to take the time and go trawling through there again!

Thanks again,

Cheers,

Rod.

why ali tube Stix :unknown:

I'm not saying it's no good but have a look at what I put in the rear tang of the 22 dasher mate
its just a tube to stop the crushing effect and so you can tighten up the king screws tighter :thumbsup:
dont make whatever you use to thick or you will compromise the stock by having to thin it out where you fit it
for one of my rifles I bought the brownells ali set but I had to thin it down first, never did it again though
and as has been said make sure it has plenty of clearance around the screw, you do not want the screw to touch when fitted :thumbsup:

Hey Marksman...

Ali tube only because everything i see & read says aluminium pillars etc.

As you say its just to stop crushing...
I actually got hold of an original brno pin/tube but think ill put a tube in incase i bodge it... :unknown:

I dont want to cut up my tyre inflator for the project...cos mine works :lol:

So i guess using steel makes sense now you mention it...as you say can do it up tighty tight.

The original is about 9.2mm OD, 1.1mm thick
The Aluminium tube i was gonna buy is 10mm OD with 1.6mm wall so as i said above there is more clearance for the screw than original...& i figured drilling out the stock a further .4mmin radius wont compromise it any... :unknown:

Guess ill fire up google now & see if i can find some steel tube in same dimensions...

Nope...well well that wont be happening...

Apparently steel tube isn't made that small...well the smallest is apparently 12 odd mm with 1.6 wall. :unknown:

I shoulda done steel trade & learned how to use a lathe...!! :roll:

Take a hacksaw with you to the local wrecking yard or scrap yard that has old machinery. You might find some steel hydraulic / pneumatic lines that fit the bill.

Stix,

If you can wait a few days, there are some different thickeness lengths of steel tube here; looks like grandfather stocked up on various sizes for tube magazines.

I can measure them all, and let you know.
Probably wont be until tomorrow, if you can wait that long.
Also, we have 3 or 4 of those 'Red Devil' butane weeder wands, and the steel tube that runs down to the burner reads just under 10mm dia, but I dont know internal wall thickness. One of these weeders has croaked, so I can chop one up if it would help?

Cheers,

Rod.

i had the advantage of having a lathe and making to measure. I also had a pair of Lumly pillars which are SS. I would look at these and see if they are long enough so they can just be cut down. He makes really good quality stuff.

Stix,

I checked the lengths of tubing in the gunroom here, but none are smaller than roughly 1/2". Plenty of a wide range of rod diameters, but no tubing smaller.

I did find this online, though. Not exactly the sizes you are chasing, but pretty close, and both steel and alloy versions:
https://www.smallparts.com.au/store/par ... und/a/101/

I still have a recollection of seeing something like steel brake line off a truck that looked to be around that diameter, but I'm yet to get over to the shed to see if I was right.

Cheers,

Rod.

I ended up getting a 6 metre length of alloy tube, 10mm OD 1.6mm gauge, for under 13 dollars...so unless i find steel, thats what im using.

I wonder how many litres of bedding compound it would take to use up the other 5.85 metres of alloy tube... :unknown:

So on that note...if anyone wants a bit, it'll be laying in my shed doing sfa for the rest of my life so you're welcome to it... :drinks:

Maybe a silly question...

In relation to the pillar that houses the action screw in these rifles (or any rifles for that matter)..

Is it necessary to glue/epoxy this into the stock seperately first...? (My guess is not... :unknown: )
Or not a big deal on a .22...? :unknown:

I imagine it wont move regardless... :unknown:..

any joint that does hydralics or supplies fuel lines should have steel lines of different sizes. i've bought steel fuel line for car restorations a lot of times from such places. i have bought fuel line in 8mm and 10 mm OD from these places. they call it "bundy line" . it's steel , but is resistant to cracking. i bought some about 7 years ago for a mates HR holden project, i think it was about $10 a metre. hope this helps . cheers
