Stuff you have made today

[Hood]

Today started with a repair

View attachment 224403

It fell off the fridge a few months back, I didn't think anything of it until I came to use it

I whipped out my ancient tube of Bison Hard Plastic Cement

A full litre of humus. The first I've made for over 5 years

It was all going so well until the last picture

Some of you know, I like to melt metal.
I do it for fun, to learn and experiment.
I have even managed to cast steel at home.

But last night melt was to separate Alloy from ferrous to weigh the scrap metal in.

First a H&S warning.
Fire safety.
Don't use water on molten metal.
It is BAD.
If you melt is going wrong, you have made a mistake.

I always have CO2 extinguisher on hand.

In this case 5KG.

The metal was 2 dead engines. Kindly donated by a mad grumpy friend.




These are dead. One had a cracked piston skirt the other the alternator was in a bad way. Ham fisted removal attempt.
But The screws, nut, bolts and anything useful are saved for future things.



I use a TYA made fire basket.
This is the warming fire. It's job is to warm the basket up and start the build up of a decent ember bed. That's were the heat is.
I am also pre warming the first items. They had got wet. Water will suck the heat out.
The item in the middle is already showing signs of melting.






Using a cylinder head to hold the hard wood scrap in place. Again it is pre warming.
You want a smoke free fire. Smoke is wasted combustibles. Also it can upset neighbours.



Biggest lump of the night.
3 bolts stopped me from completely splitting the case. They are hidden behind the alternator. So in it went.

Again warming up. This can be dangerous, if you left any oil in the engine.
It will boil.
It will burn.
It will stink.
Be warned.

Alloy when it is getting hot will show you.
Look for "Silver Cracks" appearing in the dirt or the grey surface. They appear, then the alloy starts to crumbles into the ember bed.
Then it flows out.




The cylinder head.
All the nice metal has gone.
I also pull it out of the embers, as it will absorb the heat and slow your melt down.
Last night. I used it to dry out smaller items before they went in.




Capping the fire.
Underneath you can see a lot off run outs.
I covered the ember bed to concentrate the heat.
In the ember bed is a mix of pools of metal wanting to run. Bits with steel still embedded. This will allow as much to flow out as possible.




I also managed to do a mix melt as well.
Two small motors thrown in. The alloy has gone leaving me with the copper rich parts.
They will be washed. The steel will be removed as much as possible. Then I may melt the copper out.

Too the right of them you can see a bearing race and some other odds and sods of the engine. .
They get pulled out as I see them. As they are solid They get dropped into a metal can with water.




Last stage.
Raking the ember bed and all the un-melted alloy.
Not always required, but the night was young and I had time.

The Results.



The biggest lump of the night.
It has cracked into a few smaller bits. But still a big lump.



I haven't washed this lump yet.




Smaller , but washed lump.

There was also about 3kg of smaller scraps. They are already in the bag.



This is 1/3 of a case and a few odd parts.
No point wasting fuel melting parts all ready clear of ferrous metals.
A example of the smaller lumps.



The lower crank shows the stubborn alternator.
Will not be an issue now.
It is still stuck on the crank.

The Steel hammer I cast at home.

I worked with a guy that cast a steel hammer, about as far as he could throw it ! It belonged to the apprentice and had a lose head that fell of one to many times, it’s probably still in the grounds of Carver barracks that is just across the road from the workshop

Got main slide ram off for cleaning up and shortening, My back is ok honestly, I always walk like this

Any reason you dont melt in a crucible then pour it? Smash casings with sledge hammer so they fit in.
I want to have another go at melting but I am only allowed clean fires.. gas or electric.
I have 20kg of FJR1200 engine casings to melt down, already smashed up and ready..

Today.. sliced my finger open
Turning facemill by hand to check the inserts, back of finger got wedged between facemill body and the peice Id just cut, with a sharp burr.

Today, while digging through the drawer of procrastination I came across one of those circular tuits that I've heard so much about. So finally having got a round tuit, I got on with a job that's been on my list of things to do for about 3 years: an aluminium fixture plate with 72 holes on a 20 mm pitch.

30 mm thick aluminium plate (that I got out of the skip at work a long, long time ago). The 11 mm holes left and right were already there, I just added countersinks for M10 screws. 36 of the holes are 20 mm deep and tapped M8, the other 36 are reamed 8 mm to a depth of 20 mm and then drilled through 4.1 mm in case a dowel pin gets stuck.

Hopefully that will be useful: spotting 72 holes, then drilling 72 holes 6.8 mm, then drilling 36 holes 7.8 mm, then reaming 36 holes, then tapping 36 holes was quite tedious!

@Kram

If I am melting to cast. I use a iron pot belly stove and use clean alloy.

The lot mention was not clean alloy, there was ferrous, brass, copper, plastic all mixed in.
So it gets melted and separated.

My local yard has 2 people who work in the Non Ferrous shed. One who knows me is a bit lenient. The other is not.
One bit of ferrous in the alloy and the whole weigh in goes down as dirty alloy.

So today or better yesterday (it's already Sunday here in Italy)
I managed to break the knife handle .
Tried to save it til I've decided to destroy it and make a new one
Later in the morning I'll upload pictures about
So ten minutes ago or so I've kicked out a kidney stone without problems or particular pain
It's around 4 or 5 mm in diameter but later it will appear smaller (liquid loss ,it will shrink)
Now is with his friend I've kicked out a month ago , them are closely close now
Later I'll continue the knife project and I will upload pictures

Good night

I've actually finished the knife
Cut flush the brass pin
Sanded the handle
"Polished" the blade using brown scotch brite
Sharpened the edges but they still dull (it does cut but it's not razor sharp)
Ingraved the handle using my tungsten carbide scribe (I'm not set up for wood working since I hate it)
Used my soldering iron to burn the ingraved drawing
Ingraved the date 4-2020 and my name D.C. in the bottom of the handle
Used the blow torch to darken the wood
Used oil on the handle , when it will be dry I'll apply another bit
Ps
(not Lin seed oil but just cooking seed oil)

Took the vmax for a quick spin (shopping, honest). Goes like a scalded cat!

Just kicked out another kidney stone
It's around 7mm
Again everything seemed to be okay but while making urine felt pain eard the sound (like dry firing a gun)
It has a little point also
I could make pictures of the stone if someone like to see them
No I will not someone could be hurt
