Fantastic work. Can you tell me what magic pill I could take, to do welds even half as good as those?

Thanks for the praise mate, but I'm definitely an amateur and not a skilled welder! Unfortunately no pills that I know of either or I'd have downed a few myself
On a serious note I've been melting things together for well over 40 years and while I'm not a real welders armpit, I can generally make them stick well enough for what I build or repair. The closest to a magic pill I can offer is the advice that its mostly about the weld pool. You first need to be able to see it properly, and then its really just a case of making sure its melting both parts.
A weld pool practice technique I was taught many years ago for gas welding also works great for TIG. Just grab a couple of bits of 1.6mm sheet metal about 100mm square. Lay them on top of each other and match up two edges then clamp vertically in the vice so the matched edge is horizontal.
Then fire up your torch and run along the edge and weld it - without using any filler. Once you've got that under control then do the same but with the pieces at right angles - ie an outside corner weld - again without using any filler. When you blow a hole in it (and you will) then just stop and move on to a fresh area.
Once you've got that sussed, then you'll have a good feel of what its like to have the weld pool under control.
At that point you can start playing with filler rod and fillet welds etc where you need to have the filler to supply the extra material.
It might not be a conventional suggestion for learning to weld, but I've personally found it worked well for me and the couple of people I've shown it to over the years. If you're struggling to learn then give it a go!

Hi Steve, Guys,
Not as heavy as I thought ! I expected nearer a ton. It looks very substantial. It makes the H&F ones look very puny.Best Regards:

Hi Guys,
Many years ago I was quite skilled at furnace welding cast iron. Then I recently had need to weld up a new frame for my bandsaw. I found that I couldn't weld for toffee any more. I was very lucky to have a friend that was in a position to teach me how to stick and TIG weld. He did and said very much the same as Steve has said above. It took me a while to learn all over again.
Anyone want a stick welder very cheap Only kidding...Best Regards:

Waiting for some hydraulic fittings to arrive, so got busy with the paint brush.
Almost looks like a bought one!!

Hi Steve,
That is a mean machine ! It ain’t going to take prisoners. Its really nice !
Re: "Joe Pieczynski's" video. Yes I had seen that one, thanks for the link anyway.
I'll post more later. At the moment I'm turning a piece of 45 mm hydraulic piston shaft down to 30 mm. This stuff is hardened on the outside and it goes about 1.5 mm deep. Tough stuff, I very rarely see blue swarf.Best Regards:

Definitely looking forward to having it going. Have a particular project to do that involves a bit of 6mm plate bending.
One thing I won't be doing is a Youtube style "look at this - wow - didn't expect that to go bang and bounce around the workshop"

Selector valve and hoses connected.
Selector is just a cheapie log splitter one from eBay.
When it comes to plumbing of any sort, it doesn’t seem to matter how many fittings I get - I’m always a couple wrong or short
Still haven’t decided how to mount the selector. Might make some sort of plate that hooks into one of the pin holes.
All looks very temporary at the moment.

Its alive!!!
Think I'm allowed to post a link to the Youtube video of it running, but if not then mods please remove the link and you can find it by searching in Google for "youtube OxxAndBert press"
I timed the travel and its 33s down, and 25s up.
I think its a good pressing speed, but I'd like it to be a bit faster for positioning.
I'll have a look at the flow restrictors on the power pack but the pump is only 4LPM so its likely as good as it gets without a pump change.
Still a bit to do before its finished, but nice to finally have it working.

Nice work Steve.
On the end of the shaft, is that a replaceable tip??? Asking as if not, you may want to set up some sort of protector as sometimes the ends can mushroom. Plus it will allow you to fit different types of ends, i.e. a chisel to spread something apart, or a blade for a brake press, etc.

Thanks Kryn.
Yes, it’s a screw in replaceable end -for exactly those reasons.

I bet that was a satisfying feeling seeing it go down and up. Nicely done Steve.

Thanks Ross.
Yes, very satisfying. Also glad that I painted it before I fired it up as I had the obligatory leaks and it would have been hard to get it cleaned up enough for painting afterwards. Anyone who looked at the vid might have noticed the dripping

Hi Steve, Guys,
Pity you are about as far away as you can get, because I have a tube of Locktite hydraulic thread seal that you could have had. Its a 550 ml tube that I've never opened and will never use. It mentions on the tube that it can be used for steam pipe threads as well.Best Regards:
