The next stage was to make a mandrel to mount the rotating casting on to machine the reverse side. This was made from a chunk of 1 1/4" b.m.s. which when this duty is finished will be modified to become the securing bolt that holds the two castings together.

Here you can see the rotating casting mounted on the rotary table on the drilling machine to have the six detent holes drilled. If anyone is wondering, the cords each side of the drill column is my crude method of counterbalancing the weight of the drill table. Its something that I rigged up in a hurry probably 30 + years ago and have never got round to improving but as they say "if it ain't broke don't fix it ". As you can probably imagine the drill table, rotary table and the casting being drilled all cast iron is quite a weighty lump to manoeuvre around, so I was quite glad of the counterbalance no matter what it looks like.
