Mark, did you make or buy your big hacksaw?? I vaguely remember a thread where you were asking about one?? Fun part will be erecting the heavy pieces, do you have a crane, or will you hire one???

Hi Kryn,
i was going to make a large hacksaw out of one I already had but I bought one that should do 90% of what I need (500mm x 500mm capacity) and I'll oxy the larger ones. I need to modify some blades to fit but that shouldn't be too hard.
i also have a 3 tonne hiab on my truck which will lift the posts into place (estimated weight of each post will be about 1000kgs).
Will need to bring in a proper crane to move some of the larger machines and also to lift the overhead crane into position.

ahh those bloody doctors, what would they know
When I was assistant to building a UB shed many years ago back in the pre-internet days. we set up all the UB trusses on timber, lined one end up with each other then marked out the positions for the purlin lugs on every beam all in one go. Then a simple job of welding each one on.
In fact if I was a squillion aire with nothing to do I would offer my services to help manufacture it. Unfortunately I am just a poor cow chaser.Gold, the colour of choice for the discerning person.

A bit of spring cleaning for the big power hacksaw. Will set up some conveyor rollers and stands to help feed the beast.
Have to drill some holes in the blades I have so they will fit this hacksaw. Boy are the blades hard!

The holes would be easy to do in a EDM. You might as well get one , you have everything else.

Looks good Mark.
I wonder how big power hacksaws go.
I was at an auction many years ago at a metal fabrication facility, and they had this large cold saw type machine, the blade would have been at least 3 feet in diameter.Gold, the colour of choice for the discerning person.

I saw a cold saw like that Friday, ran at a high speed and threw sparks everywhere. Remember using one when I was a lot younger, the name Trengagger (or similar spelling) comes to mind.

At least, it wasn't a friction blade, dirty, smelly things, cuts from those remained hot for a while.

Raining today so harvest has come to a standstill after only 1 day. So pulled the covers off the cement after nearly a month since last slab was done. Looks pretty good.
Time to start drawing the post configuration as making them will be the job over summer. Lots of measurements to take and decisions about the exact design. Have been doing some reading but seeing as I already have the material I can’t make to many changes.

I have some solid carbide drills which I use of these jobs. They have 2 straight flutes rather than the helical flutes on normal drills. I must say that I run them at least twice as fast (if not more) than normal drills. Steady pressure similar to normal drills. The high speed reduces the chip load per revolution as they are prone to chipping the cutting edge otherwise. I have reground a carbide topped spade drill occasionally and I do go steady with them. Does anyone else have experience with carbide drills in hard steels?
The shed is definitely not big enough but she will have to do!!

The biggest I have seen was at QAL Gladstone ( circa late 1980's) that could cut 16" heavy wall pipe.It had hydraulic jaws that could squeeze the pipe out of round if you were not careful. The blade was made to take screwed on 75mm long carbide segments. The tooth pitch was around 5mm if I recall.
It was a Kasto . I looked for and can't find one like it on Google. These days, by comparison, it is probably small to what is available now.
