Tim,
You are doing wonderful and innovative work on your making of the parts, and you are showing that you don't need a lot of gizmos to get the job done.
A lot of it is laziness and impatience on our part, and if we all did what you are doing, more of the basics of machining would be understood.
I think you have a good improvisation head on your shoulders, and you should let it keep leading the way.
Getting back to grass roots machining, great!!

And it's getting bigger too :lol:
Thanks for the encouragement John, it means a lot to me :thumbup:
I did think about using a rotary table to mill out the curved slot, but the arc's radius is over 4.5" and I only have a little 4" diameter rotary table, I didn't think having roughly 2.5" sticking out unsupported would be too good, so I figured that using the belt-drive base could give me the needed support and provide me with the perfect matching radius I needed, and after figuring out how to remove my fingers from being close to the milling cutter I just gently milled it away.
I do find that I spend more time looking at the workpiece and the machines I have figuring out just how I can best achieve the results needed, than the actual time spent milling or turning it !!

I think thats very true for most people Tim:- I quite often find myselfe thinking about something I'm three or four weeks away from making. It sometimes gets me in trouble with the Boss, she'll be rabbiting on about something, I'll be lost on thought about making something, and then she'll say OK thats agreed then, what what was that :bugeye: :wack: :zap:
:lol: :lol: :lol:

Dave,
If you look back at old mags and books, you would be surprised how easy a lot of the supposedly difficult jobs were got around.
It is only the last few years that specialist tooling like rotary tables and boring heads came within the modellers price range.
Before that, everything was done just as Tim is doing, and to me should be the way everyone should start off.
Get the basics under your belt, gizmos can come later to make the job a little easier.
I honestly think that is why the older generation of model engineers make things look easy. It isn't because they are any better machinists, but they have a greater understanding of the principles involved in making the part, and when they get to using modern techniques, using modern tooling, it looks just like they are using black magic to make the parts.
Modern machinists are getting a mental blockage, that assumes modern bits and bobs are needed to do the necessary procedures, whereas they should be thinking that they only assist in making the job easier to do. The last two hundred years or so of engineering have proved that the modern way of thinking is all wrong.
Just to reiterate, Tim is showing the ways how it used to be done, and good for him.
Now if we could get someone to show us how it was done before metal planers, milling machines or vertical slides came onto the scene ........... hacksaws and files (complete with aching arms and loads of sweat) spring to mind. Remember all those old piccies of rows upon rows of benches with chaps standing there filing away at hunks of metal. They were called fitters, because they were making parts so that they FITTED together correctly.
A hundred jobs (or even more) replaced by one CNC machining centre, turning out millions of parts that fit together perfectly. But can it make a one off, at short notice, from a fag packet sketch? I very much doubt it.
That is where we come in, but unless you have the basics, you will struggle.
