A little bit of what I do for work...

Here is one of our Deep Bore machines.  I use it to repair steam valves and overlay any kind of bore from 1.5" to 48".  It's fully automatic TIG.

That is amazing

Finished product.  This is an Inconel Overlay for corrosion resistance.

Looks like mud wasps on steroids.

 

Imagine trying to do that by hand.

Look like chicken peck marks..... I have to say Dripley they are very consistent and even.

 

I have to ask.....How do you drill out steel at that wide of a bore?

[Manimalmother]

They use a very large boring bar.

Can't blame Dripley. He's de-beeked

Very neat process. Now be able to re-bore that hole all over again.

Baddass

The machining companies we use have some elaborate setups for boring these out.  Hydraulic driven boring bars and such.

 

I can reach down 7' inside a bore and weld it.  Anything I weld they have to machine.

That is all pretty cool.
