Its Gotta Be Blue II

Postby Coldman » Tue Apr 18, 2017 3:05 am

After messing around making an X-Y-Z template for pipe corner joints I decided to make another of Jody's "open concept" carts but using 1-1/4" sched 40 pipe instead as I had a length of used pipe on the rack I couldn't use on the job and I also had wheels, castors and 3/4" short radius elbows lying around looking for a use, so here it is.
Cut all the materials and coped all the pipe ends, it turned out to be easy to clock them all accurately. All I did was chalk a straight line down the side of the piece and used it as the start point for the cope wrap.

All copes were cut with a worn wafer blade on a 5" angle grinder. I tried other methods like band saw and plasma, much cussing, the angle grinder was fastest and most accurate cut. Cleaned up with die grinder and no cussing.

Tacked up the two sides then tacked in spacer pipes

Had perfect fitups but I offset every joint as I knew what was going to happen from experience. It did happen and pulled into perfect square and alignment - yes!

Used a piece of 40mm square tube for the cylinder stand. Gonna put aluminium tread plate on it to protect paint work.

Made up the castor caster mounts and instead of welding on the casters, this time I drilled and tapped holes in one go with these great bit/tapper bits. This one is 6mm (about 1/4"). Fitted up all the wheels nice and level 2" castors and 8" wheels all with bearings.

Final fit up with 3/4" pipe handles and cable hooks just like last time.
I used 2" x 1/8" (50x3mm) flat bar on edge to frame the shelves. Aluminium tread plate will be riveted on when finished.
Made provision for two cylinders on the cart this time.

All painted up and of course me being a one eyed Miller guy, it's gotta be blue!!!

All that's left is the tread plate shelves and retainer chains for the cylinders. I didn't want to buy a whole sheet of tread plate cos I don't have a use for the rest of it so I'm gonna wait for a score. I'll post a pic when its done, might be a while.

Hey Exy, they are pure unadulterated cable hooks.

@pgk
The drill/tap bits are very cool. I think the eight tapped holes took less than two minutes after centre punching . With trefolex it seems to glide through like butter.

All the labels are worn off.

Here is the link to the manufacturers web site:
http://www.pretooling.com.au/products/c ... -taps.html

Looks like an Ozzie company, how bout that.

If you look at their little demo tube they used an electric pistol drill and operated the bit dry.
It works fine dry, I used a battery drill and could feel the dry friction. Added trefolex the next hole and no resistance, just glided through. I have the full set from 3mm - 10mm for a few years now and have not broken a single tap yet. Thickness of plate you can tap is limited by the length of drill extension that must penetrate right through before the threads engage but in every case this length is much more than the hole diameter. They claim up to twice as much but I haven't measured. That means the 10mm bit can be used on 20mm plate. Impressive.
