It's something I have been coveting for some time and I look forward to being able to press stuff instead of ramming. However I feel the need already to modify it somewhat.
The problem is that the maximum height of the workpiece is 8.5 inches [215mm actually]. Ideally I would like to be able to press a 1lb rocket with it, which would require at least 15 inches of height. [7.5 inches for the tube, and 7.5 inches for the drift]
The circular anvil is removeable so my initial thoughts are to take it off and somehow clamp an anvil [bit of I-beam mebbe?] underneath it. Whilst there are two holes at the back of the press, there are no holes at the front where mounting would be required.
Has anybody got any advice on drilling cast iron, or any thoughts on a more elegant solution? All advice gratefully received....

Its the same idea as you have had, It will be much easier to do this rather than a more complex solution. you could make it adjustable by making 1" shims to lower and raise the press. Get some nice long bolts and bolt the entire lot down fron and rear using the holes on the press.

This way you could accomodate any depth of case.
PS - there is no real problem drilling CI. Don't use a lubricant - medium speed - swarf/powder is very dirty!! Keep any holes away from the edges, as yes it is brittle, but if there is plenty of 'meat' around the hole and you keep any forces in compression when you bolt it up, you will be fine.

I used this for several rockets, however it was not a big enough press to press 1 lb BP rockets (1/2 ton press) I was able to press 1 lb rockets that were not BP based however. The steel plate is height adjustable, I easily drilled it with no problems.
However, I have since got a 4 ton press and this sucker really does the job. compared to the old one--
