Alright gentlemen, here is one of my "lemons". Feel free to pucker up. :D
2 hours to set up, and 2 minutes to cut. :loco:
I like this thread. It could turn out to be epic! :lol:

For fly-cutting the entire face, I couldn't clamp this part directly to the table because the clamps would interfere. I had tried clamping down using that interesting trick Rob showed us in his angle plate thread, but I couldn't get a good bite on the part and was limited in my placement of the clamps.
A second vice would certainly have helped but I don't have much room atop my riser block to clamp anything down, so this might be out of the question.
Since I don't have an adjustable knee, and only about 4.5" of quill travel, I seem to always be having to come up with a setup that looks like the leaning tower of Pisa. This one was surprisingly rigid compared to some I have come up with. Though I have to admit that I DID purposely stand out of the predicted path of travel, should the part have let go!
I could have cut the steps down either side by clamping directly to my riser block but since I already had a setup that was working well, I wasn't about to rotate the riser block 90 degrees and re-square everything.
I couldn't clamp it directly to the main table because I can't reach it without using a really long extension, which wouldn't have increased the overall rigidity of the setup.
I've learned to get a lot done with this combo machine, but sometimes I scratch my head for days trying to think about how to get a part to hold still while I mill off the parts I don't need.
I should really post a thread illustrating the work envelope of this machine so that you guys can understand why a lot of my setups look so crazy... :)

Sparky,
No one is laughing at you, we are laughing with you.
I think I know the type of machine you have, is it like the Smithy Combo.
I had one of those, only sold it (to a mate) because he kept on nagging me. He still has it and still going strong.
Luv to see a pic of your machine Sparky.

Hi Sparky
At the end of the day you got the job done :thumbup: there will always be times when we have to make do with what we have at hand in or home shops to get the job done ,, all part of home machining :med:
Good save by the way nice T nuts :dremel:

Sparky,
Well that certainly explains the need for your set up. Sometimes there is no other option. It's obvious that you put a lot of thought into clamping your part to make the clear path you needed for your cutter(s). I noticed the spacers you put in to move your part away from your riser to avoid cutting into it. That shows good planning and that you know what you are doing ahead of time. :thumbup:
I'm new here and don't know your machine. I can't tell what kind of space / work envelope you have to work with from your close-up photos. I was just offering a possible alternative without being able to see the bigger picture. No offense intended or implied. DaveH is correct. Just trying to help and show support, because I know I've done things that would make a real machinist cringe. But I have to work with what I have. It's all I've got.
