Bryan's 4Kw motor Conversion Part 2 The testing

<< < (6/6)

ruddycrazy:
I made a typo on the diameter the pipe is 170mm diameter with a 5mm wall thickness and the lengths are 4.2 metres long, now as the turbine will be ontop of the hill I will just go 2 sections each for the tower and gin pole. Also a 170mm diameter pipe will be used for the joint and bearing housing for raising/tilting, and i have some pile rio sections a metre diameter and about 1200mm long to use as the foundation. It will be a mammoth job to dig the hole and it will have to be nice and dry to get a concrete truck up the hill as theres no way I will be hand mixing the concrete needed as more than likely a couple of cube's will be needed.

With this new job I will be saving for the wire and I did ask at a scrap yard how much a roll of the thick wire on some of those rolls saying I will be paying cash and was told well mate come on in with some and we can talk a deal.

Cheers Bryan

So around 7" pipe?

I was like, hot damn, 1700mm pipe is sewer grade, but then your thickness was awfully thin.

Talking with one of the TA's today about the pipe and he said you better it done while Jon is still here and Jon is the guy that hired me who is retiring in 3 weeks. So this arvo after work had a look for the gal pipe fittings and only found 2 pairs of the 3 way ones in 2 different config's., so they are enough to put the back stay on and I need to measure if I need the front stay on but I do think just the back stay and the head board on the tray will be enough.

I am going to get 5 of the 4.2 metre lengths so I have the option of going higher and enough to do the bearing hub pivot point, I have a couple of 25mm 200 mm disks here so welding them onto the pivot pipe with 2 off plumber block bearings will provide a smooth pivot joint.

I do need to make up some trestles and I'll use some heavy angle iron and drill and counter sink some holes to fit the big ball bearings I have so the pipe can rotate when I weld it. Just grease up the ball bearings and it does provide a cheap rotating device, then I'll use my laser to line the pipe by adjusting each trestle.

I am thinking of welding it up on site so no moving is required and getting it all to stand up is one problem that needs a solution and I'm sure to get a hand off my neighbour and his 2 workers.

So the planning goes on

Cheers Bryan

SparWeb:
Doesn't mean moving the welding rig instead of moving the pipe?
