Quick job this afternoon.
Piece of equestrian arena equipment.
Someone forgot their grease gun...
Washed the first bearing off with oxyacetylene. No damage to shaft.
Other bearing has failed and ate the shaft. Turned a drilling jig, drilled 5.0mm and then 12.7mm.
Machined a stub piece from EN8 to 1" with a ½" step.
Heated the piece of equipment up and tapped the new stub into my drilled hole.
Shrink fit.
New bearing fitted a treat.
Left the weld under 1" so I didn't have to grind.
Reassembled new bearings onto shaft with plenty of nickel graphite.

20 years under the hazel tree in the garden had taken its toll. Cheaper to fix they're stupid money to buy new.Customer wanted two sections of straight s/h fence,made into two sections of quarter circle segments,he had one partly bent and one to copy,I’ve left the partly one alone ,as I’ll make that into another straight one,I’d rather start with a fresh straight one to make curved,all done on the outdoor fly press,with assistance.
It’s wrought iron,so more malleable than steel.

A few post ago there was a debate on points.
In a recent bundle of tools. This box was found.
In it was this bit of rust and steel.
I recall doints points and condessors in the 80's up to the late 90's.
I had a 104. The dizzy was deep down. I used to carry a spare coil, HT leads and a complete dizzy. As the dam thing would dift the points gaps.

Today (well yesterday and today) I finally fixed the starter solenoid on the Landy, lots of laying on the floor had the motor out, got the solenoid rebuilt and put back this morning and it starts first time every time. The kit was easy to fit and cheaper than half an hour with my tame mechanic.
I am pretty sure it would not have lasted much longer as the plunger was looking horrific!

A quick file and wipe over and they will be fine.

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).

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.

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.

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?

After sheering water pump bolt in Audi A8 yesterday...
Making a drilling jig...
Managed to drill out the old bolt and set a helicoil (tang still to be detached)...

@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!
