Thread: Advice

Ok thanks Grahame. Mate i'll be sure to post some pics when it's all done.....

Does anyone know of any other metal places in the Blacktown - Minchinbury areas please? I tried Edcon for some 22mm steel pipe with a 2mm wall and a 19mm steel pipe 2mm wall to fit inside but they can't help. So I'm wondering if i'll have some luck smoewhere else.

Thanks guys

The best place for steel around our area is Sims at Dunheaved. They sell at wholesale rates to public. The only catch is that they are OH&S Natsies, and you have to bear that in mind when loading etc.

Thanks for that. I also found another place too.... their called Orrcon at glendenning, they seem quite good on their prices too.

Garfield you wont find anywhere that will have 22mmOD 2mm WT that 19mmOD will fit into ,you need to be smaller than 18mmOD.
Your only option if these are the sizes you require is to turn the OD of the 19mm to suit the ID of the 22mm.

Mabey it is available.

I have purchased similar sizes before for a table saw trunnion that I built a few years back.. It will cost you a packet though. $$$$

There is a place near Blacktown that will have it. You will need to ask for internally ground bore tube. I can't remember the name of the shop, but here are some directions.

Going nominally west down Sunnyholt towards Parkleah from Blacktown, you turn left at the + intersection before heading up the hill. Continue down about 1km and turn right at the servo. The steel place is 50m up there on the RH corner.

Just curious fossil if you can get the sizes of tube that Garfield requires im amazed that they slip inside each other without the aid of a 250 plus tonne power press.

Garfield,
Does this help in seeking dimensions for for
Pipe nominal bore
Tube OD Outside dimension

I just miced an offcut of the stuff that I got a few years back. It is 1" ID, (not nominal bore). As I stated before it has been internally ground. I didn't use tube to go inside the 1" tube for the trunion setup, but used solid round bar of 25mm diameter, giving 0.4mm clearance. Once a nipple is fitted, and the setup greased, 12" of this setup gives a really nice strong hinge for the T.S. trunion.

You are 100% correct, in that any telescoping sizes in NB pipe will not fit, hence my suggestion to the O.P. to consider internally ground tube.

I just looked it up on whereis and the place I was refering to is on the corner of Turbo and Binney rd's at Kings park, between Blacktown and Marryong.

Good luck.

sorry for the no reply, but my computer sh@t itself and I couldn't view for a couple of days.

Thanks guys....

Thanks Grahame, I really appraciate that link but I don't at all understand it...... So basically Its just impossible to get a pipe of around 22mm with a 1.6 - or 2mm wall and a 19mm pipe to fit inside??

Garfield you can try ERW tube you can get it in 22.2mmOD x 1.2 or 1.4 mmW/T,this will accomadate 19mm ERW tube.
Only problem is your W/T (the welding concern)
How far does the 19mmOD tube or pipe have to slide in side the larger diameter.
As said before may be easier to get some 19mmOD pipe and turn the OD of this (you can get 19mmOd in 3.2 W/T so taking a bit off the OD would not effect its rigidity.
Depending how long it may need to be turned could probably assist you with that.

Pipeclay, what does ERW stand for?

I need the pipe to go inside about 300mm deep

Also when you say that the OD could be turned, do you mean that it would need to be lathed or something?
