The Honda Racing man diced with Keith Farmer for much of the session, but the Northern Irishman’s charge was brought to a halt thanks to a heavy crash late in the session.
After threats of cancellation and a lengthy delay of two hours thanks to heavy rain, riders headed out onto the drenched Scottish circuit for a single 40 minute qualifying session.
Xavi Fores, Claudio Corti and Luke Stapleford were all early contenders for pole as they clocked quick laps with a break in the clouds, but just as Fores and FP3 front-runner Buchan moved up into first and second place, the rain began to hit again.
Former Supermoto man Keith Farmer stuck his Tyco BMW into second place, but moments later it was the returning Currie who splashed up into the top spot just as Smith’s Racing’s James Ellison clocked the third quickest time.
Fores was soon back in the mix as he moved up to second, but was deposed seconds later by Bridewell and Buchan who moved up into second and third, respectively.
And just like this morning, Buchan became the quickest man - but only for the minute as Farmer, Fores and Bridewell all went faster before Farmer and Fores began a tit-for-tat at the front of the field.
But Farmer’s charge was all over with five minutes to go as he flung himself into the gravel at the bottom of Butchers after going second quickest, leaving his S1000RR stricken in the runoff as he was stretchered away to the medical centre.
Fores maintained control as the clock wound down and with Farmer off track holding the second fastest lap, the former World Superbike rider clinched his first pole position.
FS-3 Racing Kawasaki’s Danny Buchan completes the front row just 0.031s clear of McAMS Yamaha’s Tarran Mackenzie and Andrew Irwin, while Christian Iddon rounds out row two.
Luke Stapleford heads up row three for Buildbase Suzuki ahead of Jason O’Halloran and Quattro Plant JG Speedfit Kawasaki rider Currie, as Oxford Ducati man Tommy Bridewell completes the top 10.
