Hey man, by aqua blaster, do you mean water blaster or soda blaster?  Or something else entirely? Cheers

I had one of these systems years ago when I was manufacturing replica Sports cars. It used glass bead mixed with water. The ued bead / water was collected into a hopper and dried off before being recycled.

You can buy soda / sand blast pots for around £150 - £200, but it's an open air total loss system ! They give the same sort of results as shown in this thread.

Excellent work so far BTW. 8)

Well we at off again, other things have got in the way, but the engine re-build has started.

The bad news is it's 2 years since I stripped it and I'm struggling to remember certain bits   :(

Some help would be much appreciated gents.

Firstly, the hole in the threaded head above the crank centreline, does anything go in it?

and 2ndly I seem to have two bolts left over. The problem is I bagged a load of them up and sent them all for blasting and plating, silly mistake.

one looks like M4 and the other is M5, can anybody shed a light on where they go?

and 3rdly

Does the top ring (I think its the top ring) sit with the larger dia on the bottom? ie as in the Photo

Thanks in advance

Not sure about your bolts and hole but the manufacturer's stamp on the piston rings (adjacent to the gap or end) always goes up.
