When we made all the cuts on our two bikes, we just pulled out the bolts, made the cuts, and slipped the bolts back in. Some bolts don't get pulled, so the engine isn't going anywhere.
We used everything from a metal-cutting blade in a skilsaw to a hacksaw to a dremel tool to a 4.5" welding grinder to make the cuts. This is not a critical area as a long as you end up with a true surface (perpendicular), and the dimensions are within a 1/16" or so.
We were surprised at how well the dremel tool worked! With a metal cutting disc, using moderate pressure to let the tool cut at its own speed, the little thing was really easy to control and very precise. If we had it to do over, we'd probably leave all the bridge-building equipment on the shelf. At the rate the discs were worn down, only two or three discs would be necessary to make ALL the cuts on one bike. If I do another RYCA, or need to chop on the small parts of the frame on any bike, I'll use the Dremel.
One tip -- it is easy to cover up the air cooling slots on the dremel when holding it in various positions. Let it breathe, or it'll overheat.
It is scary to start cutting like this. This is where you know you are doing things that can not be undone!
On the other hand, it sure feels like progress in a situation that seems to be taking for f***ing ever!
