Stuff you have fixed today

[My Old Landy]

Today I fixed the Raglan 5" so it would screw cut 4 to 32tpi instead of 32 to 60tpi
With thanks to my forum friend for the 40T gear, I made a mandrel so I could split the 20/26T gear set on the S&B.
I then parted the gears, drilled the 26T to accept a couple of drive pins and fitted it all back on the lathe.
Result is the gearbox now selects the correct tpi (and I can even do some metric).

With @matt1978 help we figured out why gas was ******* out of the wire feed liner tube going to the euro connector.

I was missing an oring on the Teflon liner.

Still a bit sooty, but a much cleaner puddle on AC.

Need to check with a steel liner and see if that is leaking gas.

Ive often wondered where that soot comes from that you see on welds from time to time. Is it a gas issue?

It's the magnesium vaporising across the arc. Completely normal and can be virtually eliminated with correct torch angle and gas shielding.

This is from today and completely untouched.

Every day's a school day. Thanks mate for clearing that up

A bit of fun.

A tired, but complete Mamod.

In bits. I wanted to keep the sadle attached, as removing it can lead to blocked pipes when assembly.

But it had other ideas.

A held it in place with metal cable ties and soldered it back on.

The brass is leeching the zinc out, due to age and heat.

This is to show how well the metal does clean up

All Orginal parts.

It was given a few soft steams before it was ran at full heat.

It does need a few more runs and tweeks of the piston spring as it beds in.

 

[redlig]

One for Ardvark.

 

[The_Yellow_Ardvark]

More fun.

I knew this needed a lot of TLC. But it threw up a lot more.

Untill it was striped I could not see a lot of hidden issues.

This shows some of the issues.

No level plug, no level plug boss.
Rust.
No whistle.

A leak. This only showed when the boiler was hot. A cold pressure test did not show it.

Not a neeat repair, but it is steam tight.

New level plug boss sodlered in.
The 2 boiler studs had let go as well.
The normal fix is to remove the end cap. Soler in two new screws from the inside. But this bloier is what is called a dimpled end cap. Getting them off is a pain.
So, i had to solder the nuts to the studs, and to the end cap.
It is still hot when this image was taken.

Agian, just to show how good the metal was.

Getting ready to do a cold pressure test.
So far the only new bits are the boss and some BA nuts and bolts.

A rare bunner and rivet scutlle.

A new pressure releif valve is fitted at this stage.

In steam.
Again, it needs a few tweeks as it beds in.

I have one of these, but need a new safety valve, where would you advise I go for it?

Now these a blast from the past. Had one of them when i was a kid

Sadly I never too a picture of what I cut and welded, nice to see a katanga again in the flesh

@The_Yellow_Ardvark i don't suppose you have a working roller in need of tarting up that you'd part with, I'm after one for my little boy as he's machine mad!

Big Merc. 4x4, complaint:- lack of power and very sluggish pulling away, no warning lights on.....
£80k car, £15 generic rubber mats.....

I wanted to take a knife to the rubber mat and cut it to the shape of the proper ones, was told not to so I put it in the boot.

Thanks to @The_Yellow_Ardvark inspiration from last sunday, I got a temperature switch for my '70s tcp. Hard to believe how old that is....

I've still got a decent supply of tin/lead flux cored solder, flows much better than the non-lead stuff.

You would be surprised at how often this 'may be the case'
