This one if I remember correctly came out of the Rubicon bush near Eildon Victoria or maybe one of the sawmills in that area.
A bit of a giggle for Ray (wheelinround), in that link of the Alexandra...

Hi Elton :D
the specs I gave are for the Rc series of BSPT. (damn metric) :rolleyes: :D

Hi Rob
the BSPT dies as Techo says are tapered to produce a tapered thread at 1:16 taper not including the lead in taper that every die has.
I have just completed a job with sockets and valves and...

Hi Rusty
I'm assuming you are using 205 housings as you could've got imperial bearings to suit.
UC 205-16 they are, or used to be
Not that it helps now lol

Phil

Not me Peter but wow, congratulations.

Phil

Hi Rob
My thread cutters (that plumbers use) cut tapered threads.

Phil

Hi Dale
You name it and you can use it.
Old piston rings, brass, copper Bakelite, ebonite...
We use 1/4" rod in roughly 4" circles and in another area we use leather.

Phil

No worrries, thanks anyway Baron.
This is a tough one to get any information on and I only really needed a pic to see what the handle on the air valve looked like.
We have two, well one with the...

The eccentric is on the shaft and the eccentric strap goes around it.
Yee ha, something I know.

Phil

Hi Dale
Normally and generally speaking the hole is reamed to size and the shaft is slightly undersize.

Phil

Hi Baron
it is actually a hydrostatic lubricator and although most of it is polished off it says 'Vacuum Lubricator Co.' and the company was situated in "The Albany", not 'Albany' but 'The Albany'....

Thanks Ken
that explains what went wrong, here's me thinking I got a packet of duds.

Phil

Hi dale
The walk bracket is missing.
I'll ask at work as at the moment we have a plethora.
My list is beginning to add up. You may have to come and visit lol.

Phil

Hi Kryn
I look at it this way, my bits are correct, the rest is just old looking. Don't worry, noone else falls for it either. :rolleyes:
There was another little valve that needed replacing as...

Back onto the hydrostatic lubricators, this time the one off the Ruston engine that drives the beam pump.
A couple of new bits and fresh packing for the glasses and it should be right to go.:o...

Damn you give good answers Bob.

Phil

Hi J
I did a couple of airline threads over the weekend and used this stuff. http://www.henkel.com.au/3320_AUE_HTML.htm?nodeid=8802639020033
Everytime I use it I don't get any leaks, probably more...

Hi Dale
If the loose pulley is on the drill, then you only need the one fixed pulley on the lineshaft.
As you move the belt over to the loose pulley on the drill it rides across the drive pulley on...

Hi Dale
this should explain how but if you need more info let me know.

Hi Dale
I have all the info you need. I'll hunt it up and post it here.

Phil

Hi Bob I'm sure this crowd will make you one. Don't know the price or shipping but... http://www.pearlengineers.com/spur-gears.html Phil
ps they are in India though.

Hi Bob,
The Macson which is pretty much a copy of the Cincinnati has the same instructions as Richard gave.
A bit of graphite only.

Phil

Hi Kryn
You could just hit the pause button.

Phil

Can't help on the post Bob but I thought it was like clay that it was covered in.
I am probably way off though.

Phil

I just watched the video and was wondering if you need the whole length threaded or just the area where the third nuts (half nuts) clamp.
It would be easier to screwcut a shorter section in the...

Hi Pete
I'm sure the flange is going to get a good dose of boot polish and become like the rest of the boiler very soon. :D
Those gauge glasses could be very handy as we use them on the lubricators...

Well the sparge is finally finished and I am happy to say I learnt a few new things about pipe threads as well.
Of course the proof will be in the pudding but I'm pretty happy with how it fitted up....

Phew on the 55 deg typo Baron, there are so many discrepancies on the pipe threads that I thought that may have been another one I hadn't found yet. :D
I had never seen a tapered bore thread either...

Now Pete, you know they didn't have welders back in those days and yes there are some bits that are welded and they are also well (and sometimes not so well) hidden from public view. I don't have...

Hi Baron,
I'm using pressure rated fittings on this job and it was a surprise to me that they are actually tapered threads in the female bores. I didn't think they came that way but these did...

Now, the insanity that is, tapping a BSPT thread.
Originally I was going to tap the hole BSPP which is paralell. I borrowed a tap and it had BSPF on it. I looked up the tapping size for BSPF and...

I thought about that Kryn but the flange on the boiler is (at the moment) a permanent thing and the flange I am making is replaceable. It is better to machine my part up concentric which is easier...

Hi all
here are the pics I promised. One of them is a bit ordinary so I will take a better one later to illustrate what is going on.
I have a minimum spec I want to keep to which is the OD of the...

I was lucky enough to tour that place on a trade school excursion. I remember the chrome baths as they checked our pockets when we left that area:D.

Phil

A flexible shaft drive from the motor to the reel would make it interchangeable.

Phil

Hi Michael
correct on all fronts.
The more joints, the more potential leaks and the more work at inspection time. We have a rule at work that there 'will' be no leaks so it is good practise to lose...

I'm surprised I didn't pick that one up Michael.
Touché' Pete. Lol

Phil

Stix and Michael,
I would swear you two are standing in the boiler house.
You have just about covered every conversation we have had about this installation.
I will expand further tonight when I...

Hi all
I nearly got the flange for the sparge pipe finished but...
Instead of screwcutting the thread I managed to procure a BSP parallel tap to do the job. The tapping size is 24.5 mm, it even...

Hi Dale
I can supply a threaded taper pin and reamer when you get to that stage.
All I need is the diameter at the big end and the length of the hole.
The reason for the taper pin is so that it...

Hi Pete
I'll need a pressure pipe ticket in our situation but threading I am allowed to do myself, plus, it is a lot easier to replace the sparge if and when it needs it if it's threaded.
Damn...

Hi Ken
no apprentices, they only want to learn G code nowadays, not basic engineering skills. It doesn't look good.
If I get crook, I have to get better, simple. :D
No new shed on the horizon yet...

Hi Kryn
after visiting every steel supplier in town I started to visit heavy engineering places as well. The place I got the piece from is the place that fabricated the beam pump for us. The owner...

We are fitting an injector to one of the boilers at work to give us an extra means of putting water into the boilers.
To do this I need to make a flange that is not available off the shelf.
It is...

Hi all
the lubricator drain plug worked, woo hoo!
I have an issue when cutting threads where I take great care in getting the gear train right then blank out when changing the levers on the...

That's what I like to hear.
Looks like you have a job that I could envy. :2tsup:

Phil

Well said. Every time I go there for anything they offer to get it in for me.
I've given up.

Phil

Hi all
first up, many many thanks for the kind words which I find hard to take guys. I am always sitting here in awe of the stuff you guys do. I have learnt heaps just by joining this forum, easily...

Hi all
good news on the dog point front, Keables have 86 in stock and as the lady explained "they aren't a real shelf mover" :D
Amongst other things I am going through all the hydrostatic...

Exactly what .RC. said
At least in the last 35 years it has. That's why it is called nominal bore due to the bore varying with wall thickness.
OD has always been the same on pipe.
Tube is a...
