Another bodgers lodge.

This is just a wee look at another bodgers lodge [only on a slightly bigger scale ] to JS. These are a few pics of what the brother and his fellow turners and millers turn out. Some parts can be 20 tonnes and more mostly oil/ gas related. This is where I get most of me tooling through [at a good discount ]. also get a lot of me steel [offcuts ] for free well, not quite free, they scratch my back I scratch theirs. I do their building. Thought this might be of interest to some of you.

Cheers

Looks just like that supergun from the 1980s/90s

Hi Ady, Don't know about the "super gun" but the bottom pic is a "super alloy " Inconel 718 weighs approx 1600kgs, used for sour service at high temps. Mega spendy ££££. I think that would be a case of anyone who stuffs it up , "pick up their cards on the way out "

Doesn't look a bodge to me, looks like big serious production and as Raymond says "Stuff that up and collect your cards on the way out"

I used to have a TOS lathe 11" centers and 6' 6" between centers but scrapped it a few years ago as it was attracting the wrong sort of work. Very expensive jobs that cost if they went wrong but more importantly for a one man shop it tied you up too much.

When you are only selling labour you can make as much with 10 jobs you can hold in your hand as one job that weights a tonne, literally. In fact often more if you have a minimum labour charge, three 20 minute jobs work out to 3 hours.

Raymond,

What an astonishing bit of machining in Inconel 718 ,for anyone who
has tried to machine this material would know.

Back in the late nineties this material was selling for £25 for a 6mm
thick slice about 2 3/4 inch dia to the gas turbine constructors to
make turbine wheels.Works out at £1200 a foot.

I bought some in bar form is really tough stuff to work 2 thou is a heavy cut
on a Myford and milling is even more fun.
Some of the wheels seen here in photo album "Turbine" blanks have to
be gashed first with an angle grinder disk .
I eventually found the best cutters to use were these dremel type
multi tooth in the photo ,they are not really milling cutters but work well enough
and are cheap, real cutters for this material are too expensive to remove
from the packaging.
The swarf comes off like wire wool from the dremel type cutters running at
about 1200 rpm keeping the feed as high as possible.

The 3 wheels on the left were done manually ,the one on the right foreground
is a bought cast wheel and behind a test wheel in aluminium for cnc file.

You have to take you hat off when you see the type of machining in the photo's
that you have shown ,absolutely brilliant .

Hi John, The part you mention was made by me brother a couple of months back. It was made entirely on a WFL Millturn. I did ask him if he knew what the Inconel cost was and it was just shy of 155k so god knows what the part cost!!!. It is in service offshore Australia. Probably pay for itself in a few weeks. Had a look at your Turbine album and a very nice job of the inconel parts, well done. Is it 718 or one of the other grades ? I have a few pieces of inconel 718 and 625 kicking about, even have a bit of Rene 41 they are only small bits about 60mm Ø and around 80mm long. I will never use them so if you could use them just pm me and I will get them off to you. Glad you found the pics interesting. I have added a few more to the album
