I don't know if you want to remove the flywheel or the crank pulley, but for a "universal" crankshaft lock, the "rope trick" works on any piston engine. It's been posted here many times, but to save you the search, here is my "canned" version:
NOTE: This is written for the B21/23/230. You'll have to adapt it to your B280 where necessary**
1 - Pull plugs and rotate crank to #1 0° TDC Compression
2** - Verify #1 and #2 valves closed - look thru oil fill hole, cams pointed upward.
3 - Rotate crank about 90° past TDC
4 - Stuff about 3 feet of clothesline into # 1 plug hole, leaving 6" outside
5 - Use socket, breaker bar, and pipe extension to loosen pulley bolt
6 - Tighten bolt the same way, but start with crank about 90° before #1 TDC Comp.
To my knowledge, this is the only "trick" holding tool alternative that allows tightening the bolt to book spec of **[I don't have B280 spec]
Here's what some 1st time users had to say:
"The "rope trick" for holding the engine still while removing the harmonic balancer bolt worked like a charm. Honestly, I doubted that it would, but WOW!"
"I finally had an opportunity today to use one of the "rope" tricks to help take off the crank bolt. All I can say is - it worked like a charm! Two seconds and I had the crank bolt off..." (6/7/01)
"I did this a few weeks ago exactly as Bruce described and it couldn't have been easier." (5/29/05)
"....the rope trick worked like a charm to loosen and tighten the crank pulley bolt!!," (12/28/05)
"tryed the . . . method without any luck but the rope trick worked fine to remove the pully bolt" (1-10-06)
