I have made it to the point in my build where it was time to do the rudder pedals. I recently added a second printer to my stable, and kind of kicking myself that i didnt go for a bigger build volume. So I set it out attempting to lengthen the Y axis on my S1, and have come up with what i think is a pretty decent result.
There were three parts to the process. The first involved removing the build plate, and drilling and tapping a new hole for the limit switch screw. this gave me an additional 5mm without much effort at all.
The second part involved removing the belt tensioner on the Y axis, and replacing it with a 3D printed part. Doing both of these got me 262mm in the Y axis. The rudder Pedals are 265mm so i just scaled them down 3mm in the Y axis.The only other thing I had to do was find a build surface big enough to strap to the existing plate. A ceramic tile I had laying around did the perfect job. I just used some exterior painters tape to to attach it to the build plate on both sides. I did slow the print speed down to 40mm/sec due to the extra load/momentum the tile might cause
I haven't taken the measurements but it should be possible to do the same mod to the V2, although the bracket will need modifying. I have included my custom bracket here also if anyone wants to give it a go.
I was surprisingly happy with results i got form this given I didn't have to purchase a thing.
I think with a longer Y axis extrusion and a longer belt you could get to 300mm without too much trouble.
