ive got a milwaukee fuel 18v gun, it smashes every other one ive tried, including snap on , dewalt and hitachi. (the other boys with these brands keep pinching mine daily) fucking ridiculous what size bolts it undoes. 5ah batteries last like two weeks or more using every day. havnt touched an air powered one since i bought it.
another route iv done on a few cruises is dunedin to waihola via the coast road, then a few beers and a snack basket at waihola pub, good for pics etc down by the lake too. not too big a drive not too short either.
ive heard good things about getting gearbox internals cryotreated . between that and better bearings it should make things hang together a little better?
got taken to nzta over a trailer i did a wof on, and then was sold, apparently surface rust was not surface rust, (it was) we won, but jesus christ the mind fuck they put you thru makes you paranoid / arsehole wof guy.
the one i built bout 15 years ago is still going strong, thats with massive cams and 8500 rev limit. they are really strong engines, pistons have heaps of meat on them.
