The BB was a pussycat. Just the standard tool and my long breaker bar no heat required just put some WD40 through hole in bottom of BB bracket. If that fails my next stage is the impact driver which usually works.
Been rebuilding wheels today, the hubs and rims were in good shape but the spokes were very rusty. I expected more trouble removing the old spokes but they all came out clean except two which just snapped at the nipple under the strain.
It took me about one and a half hours per wheel, including truing, so not too bad. I take my time rather than trying to rush.
Here are a couple of before and afters and old vs new spokes and nipples.
