All in stainless steel. Customer wanted to reuse the existing crown wheel and cams. Rebuilt with new bearings though.
Old one had lasted about 80 years.
The pan inside tilts back and forth as each side fills with water, forcing the cams to push into the crown wheel and rotating it.

4 louvre panels, individual louvres cut and folded, then pop riveted together. Not very exciting, but good practice in accurate drilling.
Aluminium angle, and 1.2 sheet.
They re about 800mm square.

Chain slings and something to do with boats.... all marine grade stainless.
Links formed from 20mm bar, rings from 25mm bar. Various length links to customers spec.
All cut, bent, full strength welded, then polished out.
Other bit from plate, pressed into the correct radius curves, then assembled and welded.
Links also formed around the lifting/towing points, welded and polished out.

Similar to some I did a few years ago, but theses are more work and quite a bit bigger.
They are subsea cable joints. One half is connected to an offshore power generation unit of some form, the other to a gert cable, fibre optics, and all sorts or stuff involved.

The inner is removable from the outer part. The white stuff all over the welds is for inspection purposes, it highlights defects in the welds which would need rework. Every single weld tested in this way. Not particularly high spec testing, but does the job.

The flanges and octagonal plates we bought in waterjet cut for speed, a key issue in this job, due to a very tight schedule.
The large round ones on the right are 30mm thick.
The ones on the left, were flame cut from 85mm thick plate, then machined as you see in the picture, taking over 50mm off the thickness on the edges of it.
Although we have the facility to machine these, we didnt have time, so had them done by others, along with opening the bores in the octagonal plates to the correct dimensions.

The outer frame is 60mm diameter solid bar, the ends are machined into matching male and female tapers, then bent. Lugs welded on at this stage makes life easier. The other bars that make up the outer frame are all scalloped to match the other arms, to form a good fit up. Accuracy needs to be pretty good to ensure the parts go together and give the right dimensions and hole centres.

They are then given a coat of Zinga on the mating faces, then assembled. Painting done by a specialists, they get a nice coat of bright orange epoxy.
