If anyone is interested in this little trick; for the larger bit, you set the router up to cut an outside "profile" with a .5" end mill, or .5" ballnose; whichever you prefer. Then set your depth as desired. In this case I set it to cut 1.125" deep in about 3 or 4 passes to get a nice roundover. Of course it did need some sanding to get it really smooth.
The smaller, un-modified bit should be set to cut ON the line of the profile

Wayne, I got the idea to do that from Joe Crumley a few years ago - cheating, and using a round-over bit. You can actually get some beading types with a point in the middle - but in each case it does not matter- you can just remove the 1/2" bearing, and run a 1/2" end mill in with the same offset, to finish the edge down to the background. It saves heaps of time, and makes a 2D letter in vectors into a 3D one. Great idea!

Wayne, doesn't Aspire have the ability to enter bit geometry? I know Joe Crumley is famous for figuring out ways to cheat the router, but he's also famous for occasionally destroying a panel or spoil board while cheating. I had a giant round over bit that was not in the standard bit list and was able to enter all the geometry measurements myself so Artcam will use it's geometry to cut the way you want it to.

I've just remembered - the rounding-over cutters without the bearings were called Brad-point bits. They have a centre diameter of about 3/32 or 1/8" and about a 1/2" radius, and one a bit bigger.

Yes, It does Dave. I just looked it up. Aspire has a couple of roundover bit profiles but you can't just make a new one by changing the values like you can with the other bits. I had tried before. But you can draw the right-hand side of your bit profile in a sign program, to scale, and import the vectors, or draw it in Aspire then add it to the permanent list. That's pretty cool. I've just been doing it my little primitive way but I'm going to try that now. Thanks!

Wayne, Enroute lets you do that also - I tried- but I didn;t find it overly successful, so in the end, I went back to the manual method of 'tricking' the machine, by just selecting a tool whose geometry was basic and only I knew that wasn't the one that was inserted.
That took less time, in the end, after fiddling with creating new profiles that didn't rout properly when called up to do so. (Maybe I'm the dill and made a basic mistake - I don't know)
