Cheers Guys

Things have bin a bit slow on this over the last week, what with having to redraw some of the parts, and other things getting in the way:- plus I went down with the dreaded puckes.

All fit now and bits redrawn.

First job was to put the bollock right.

So plugged the holes and respotted in the correct position.

In order to get things in the correct position I had to use a boring head, just opened the holes up just enough to give a good register for a mandrel.

Then turn a mandrell up a nice fit in the hole.

Then transfer chuck and mandrel over to the RT and bolt the cylinder to it.

Then machine the rads around the rim

Turn the RT onto the horizontal and machine the pocket around the top.
First with a radius cutter

Then take the meat away

Then do the same with the base but leaving a flat for the foot to solder too.

Your probably a bit baffled as to where I'm going with this, well I'm baffled as well :lol:

Got a little done today: made the cylinder base this will be silver soldered to the cylinder.

Started life as a bit of 12mm thick brass sqaured up and milled to size.

Then first with a end mill and finishing off with a 10mm bull nosed cutter machined out a plinth in its middle.

It fits on the flat like this

I'm not going to solder it just yet the cylinder covers will need soldering as well so I'll do them together.
