Rear Axle Breather Connector

Too late now, I was going to suggest adding a couple of shallow flats so an adjustable spanner could be used to nip it up.

Quite right Dave, but as a simple breather, I was wondering why it needed 25mm of thread. I expect about half that is irrelevant. A pair of pipe grips (pliers?) would be more than adequate for insertion, possibly with a dash of thread sealant to ensure a waterproof joint.

This thing is there, as it has been designed, simply to avoid water being drawn into the axle casing when a warm axle is dunked in deep cold water while wading. Nothing more.

Gosh Bill, that's better than the original. It'll last longer than the rest of Clive's Trusty Trooper!

Right Guys

What do you think of my second attempt at making the connector?

I was going to swear blind I’d made it, but Nah I can’t take the credit for it, more nearer the truth it certainly puts my effort to shame.

What can I say? Absolutely brilliant my thanks to Bill it arrived today 15/10/21, stainless steel as well, its not going to rust in a hurry.

Did you make the complete thing using a lathe?

I’ve only got a drill press, one of those jobs you can fix a hand-held drill into, it just doesn’t compare with a lathe.

PM me the cost or it’s got to be worth the price of drink or whatever it is you do with your surplus cash???

I bet I’ve set everyone on this forum as task now, "Trying to figure out what surplus cash means" .

I’ve included a couple of pictures so you can see it in its final resting place.

Again, thank you for helping me out Bill its much appreciated.

Ok guys

I’ve already admitted I didn’t drill the connector I made from both ends for fear of the holes not lining up and the pilot drill flexing as it breaks through into the hole coming from the opposite end.

My thinking it could cause the bit to break and end up being stuck in the workpiece, can someone put me straight, do you not drill the pilot hole until it breaks through into the hole from the opposite end, just thought I’d ask?

No problem, happy to assist.
No charge, but pass a favour onto someone else; It just makes the world a better place to live if we all help each other somehow.

I think I'd be bothered about breaking the smaller drill if I'd had to do it without a lathe.

I picked the first drill, 3.2mm, purely because when I checked through my box, that one was brand new,.
As such, less chance of it wandering, and also it cut properly, so less chance of work hardening the stainless.

Since the 3.2 wasn't long enough to go all the way through without going beyond the flutes, I did swap ends, and obviously started it off, at each end, with a centre drill (In this case I actually used a carbide spotting drill as it's more rigid.)

After the initial turning down, threading, and part drilling 3.2mm in the 3 jaw, I swapped to a collet so I could reverse the workpiece and hold it concentrically without damaging the thread.
Next turn down to 7mm, drill 3.2mm and open out to 4mm in one pass, as the drill was long enough.

I wasn't sure whether to shape the M7 end with a wider rounded bit on the tip, but figured that since it's not a pressure application, it's not going to blow off.

All the best
Bill
