Turned Aluminium Precision Screwdriver.

I have seen around some really neat precision screwdrivers, from brass and aluminium. They look great, but they are rather pricey so I wanted to have a go at creating my own version.

Ordinarily, I would have probably used a 1/4 inch hex bit, but the little 4mm hex holder / bits that I used for this project were lying around, So I decided to use that for my project.

This is my very rough measurements of the sizes of the hex bit driver. I explain things a bit in the video down below.

I have also made a video explaining some of the build process. It is a bit long, as I am also using it as a test of some live-stream capabilities, but I hope it provides enough info about how I’ve created it.

The driver has turned out really well. I’m going to trial it for a little while, and decide how I like it. If it works out OK, but needs some more tweaks, I’m tempted to attempt making another one. One thing I would probably change is the overall length. I would probably shorten it a little.

Thanks for tuning in, I’ll See you all next time.


Welding bench Mod – Ditching the casters

My little portable welding bench is pretty handy, but the biggest problem with it is that  it’s TOO easy to move. It is pretty unsteady when working at the caster end. It has a little spike that you can push down into the ground to hold it stable, but as it wasn’t designed as a work bench, it doesn’t do the greatest job, especially if you are doing something like using a hack saw on some metal in the vice.

This is one of the old wheels removed from the cart.

To combat the issue, I was thinking of putting some locking caster wheels on it instead of the non-locking casters on it originally. This is a good idea, keeping it easily portable, but allowing some movement still.

Then, I thought, what if it just had feet, and not caster wheels at all? It would reduce the mobility slightly. I’d have to pick up the end to wheel it about like a wheel barrow. I figured that wouldn’t be too much of a loss, and it might prove to be even more stable than having even locking casters on the front. Plus, it wouldn’t cost me anything!

I had some 25mm square section, and i figured I could use that to make legs to go where the casters originally were. After thinking, I thought it would be hard to get a good weld on the trolly and the new legs, as both are rather thin, so I came up with this:

The new feet are made from a nut, a bolt, a piece of 25mm square section, and a short lenght of round section steel.

The nuts are much easier to weld onto the round tube. The square section pieces I’ve welded to the legs makes it easy to slide the legs into place, and then weld them on. I could have probably welded the round legs straight into the trolly, but it is made of even thinner metal then the smaller pieces I used.

One new foot welded onto the cart.

The legs slide into postion, and get welded in. I was hoping to do better welds, but they will hold in this situation. Its so hard to get good welds on such light steel with this setup, and my skills.

It doesn't look too different, but its a lot more stabe now!

So, there we have it. The only addition I think is useful on the feet now is a lock nut on each foot, so they don’t move and get lopsided, but thats easy to do if I decide its needed.

Learning to Arc Weld

So, I’ve been on a bit of a learning to weld mission lately. Over the years, I’ve done a little welding, but never anything of any kind of quality, or quantity. 


For the last couple of years, I have had an old, beaten up arc welder which was given to me by my father. It was a handy little unit, but only having minimal adjustment of the amperage was a bit limiting to my learning. Fairly quickly, it became aparent that if I wanted to learn more about welding, I was going to need something with aperage adjustment. The old welder is a Cigweld Compact 2. The minimal controls consist of a switch that selects between 2.5 and 3.2mm Welding Electrodes. It seemed to work ok, and give reasonable results doing practice welds on thick plate, but I find I wanted a bit more control, especially when I’m welding on thinner metal and tube.
