However as castings are not available for these items do you want to compare total time including making the patterns and then machining them assuming you get the casting done elsewhere? We can discount design time as that would be the same for either

I think it might be fairer to compare CNC machining from solid with making the pieces out of layers of steel plates of various thicknesses cut to profile for a one off. If you are trying to encourage others to build one. I suspect more members are likely to have plates of steel rather than a CNC mill.

Yes that is why I also showed the smaller outrigger base being done manually. These are not really suited to making up from plates apart from adding the couple of rectangular pads or the round bosses. Though I have used that method in the past, really just need to assess each individual part and use the best approach based on what materials and machines you have.
Dave, good idea. I suspect Jo's question may have been prompted by someone taking 3 days to CNC machine a small part as she often raises the point about how long CNC takes but in reality it is often quicker than making scratch parts manually though possibly longer than from castings if they are available and don't need reworking.
John, your points about the machines ability can be covered in a separate thread and I'll detail why that job took someone 3 days and I could have done it in maybe 1/4 of that time or less.
Other thread will have to wait until later as some of us go out to work, god knows how I manage to keep completing these models in such little spare time :lolb:

It is very important for someone to go out to work otherwise who is going to pay the taxes to cover for our pensions :old: ;D You wait until you retire then you will really know how hard time is to come by ;) . Can't stand around chatting I've got to go on the village monday morning walk

RayW:
Looks like an interesting project jason. I will be following progress with interest.
GWRdriver:
I will also be following along with GREAT interest as a few years ago two sets (one complete, one incomplete) of orphaned James Coombs castings came begging for a new home and I took them both in. This build is a ways down my List, but my intent has been to build a Double and enhance their looks in just the ways you've outlined, without having to admit I should have built something more highly detailed.
