Gleniffer DB2 rebuild

[RLWP]

An occasional series on an unusual engine...

 

I've just had the block of this engine stitch welded to remove a long frost crack. It's a process I have heard of, this is my first experience of having this done:

 

 

 

I'm very impressed!

Ok why that method, rather than what I would consider a normal looking weld?

[RLWP]

Welding cast iron is hard because it is a brittle material. If you just run a weld, as the bead cools, it puts the surrounding metal into tension and cracks it. There is an alternative method, which is to get the area to a red heat, then weld it.

Ok I didn't know that was cast, I am aware cast is not easy to weld, I can see the point now, thanks

[RLWP]

It is a beautiful casting. I'll take a picture of the whole thing tomorrow

 

I can't work out how they managed to cast it without the front falling off

Who did the stitch welding??

[RLWP]

Metalock in Coventry: https://www.metalock.co.uk/

 

This is watchmaking compared to their usual jobs: https://www.metalock.co.uk/on-site-services/on-site-machining.aspx

Way back early 60's the water jacket on my "Seffle" was frost cracked,( that way on purchase) a friend of mine was one of the first (as far as I know) to take on the method of repair which AFAIK was then a sort of franchise,he continued for many years & did many repairs & didn't hear of any failures & the "Seffle" still going in Jem bates"s boat

Cor, wish I could do that. I've seen that done on a big fly press, perfect.

So do I!

Nice. Was this a cold process?

 

Not trying to be klever. but when it is cold, I thought it just "stitched" and not "welded" so I am interested to know if there are other processes.

I wish I knew the answer!

Nice job Richard

 

Worth considering for my small bell-housing hole do you think?

One of these car make over programmes had an engine block stitched. An old MG if I remember.

 

I think they showed the process.

 

I 'think' the programme is/was Car SOS or summat.

Edit. Just looked it up. Car SOS. Channel 4. I think it was a MGA.

Brilliant - I'm glad to see you making progress.

 

I hope you're not lifting too many of those nice light Gleny bits with your mended hand Richard.
