Thanks Charles !
Bob, I welded cast iron bits from another barrel (I think from a Norton Dommi) with normal wire by MIG.
The first try out was on a 350 head (expendable..) with a broken out rocker box bolt hole.
That one I heated on a electric stove but I noticed that it did not get hot enough.(about 200 C )
I tried to keep as much heat in the part by covering it with ceramic blanket.
But It was tricky and it needed a different approach.
Now I use a pottery kiln and welded bits on the cilinderhead and barrel for Burney and also a 1940 cast iron VH head, all went o.k.
So thats what I use now, a top loader pottery kiln (it can reach 1200+ C ) to about 280 / 300 degree C .
I dont weld inside the kiln, it's simply to hot with the heat radiating from the open lid.
I take the part out and to prevent a thermo shock I put it on the -red hot- electric stove

pics show that 350 head

Note that these fin bits are just ornamental.
The stress I put in with the heat is 'only' on the outside.
Possibly I just got lucky with that bolt hole ?
I dont think it is doable to weld a cilinderhead with a cracked combustion chamber by MIG welding.
But you never know... perhaps worth a try ?
Looking for a cracked BSA head now

Thanks Vincent, that's very interesting.

I sent a 600 Panther barrel off for sleeving and a fin got broken in transit. The company doing the work (T&L Engineering (Bedford) Ltd.) brazed it back together. Its a good repair.

One day I'll get it running .

Bob.

Not much done (again)
But I fitted new guides, valves and a sparkplug size reducer supplied by Karol
butchered a ring spanner to make it in a thin walled tube spanner to fit that reducer.
New Westwood cylinder liner (number WCL22B at 32,15 GBP ex vat) is on it's way from the UK , thank you Steve !
Crankcase mouth has been skimmed and flywheel build up with nos bigend + new main bush.

More great work Vincent.

Hi Dave, Thanks.
Are you coming to the BOM ?

Vincent ,I've sent you an email.

Dave

Bottom end ready.
Nice detail is the cylinder boring machine on the left.
This was bought from the estate of Augustinus in Den Hague in the seventies .
Now it will reline my Model C cylinder once delivered by that same Augustinus company.
How about that for tradition !

started with the first layers of black.....what fun

Made a second spray boot, this time inside the workshop as the shed is still to cold.
Bonus is the chimney that belonged to the kiln I used to have.

that 2K stuff does funny things with you

All that beautiful work has a cost!

our women say that small children have small toys and those big children have big toys. I'm glad I'm part of this community of big kids.
