Well I took the plunge and bought the Milwaukee 18 volt offering - complete kit with battery, charger and soft carry case as I have no other Milwaukee stuff.
Charged the battery, stuffed a JCB grease tube in it, primed it and did precisely one grease nipple just to prove it works. Certainly seems to.
Next issue, this 3CX Project 8 that I’m bringing back into service has obviously been greased regularly up to a few years ago, but I don’t think it’s seen anything recently. Fair old buildup of throughly cemented grease / dust buildup round all the pins which I’d really like to clean off. My first reaction was to steam clean it, but when I did that with my Project 7 a few years back it was the start of significant rusting so I’m being a bit cautious this time.
Presumably the steam takes off the thin oil layer that’s stopping the rust, so perhaps a steam clean followed by a spray of ‘something’, but what? If it was bare steel I’d use Shell Ensis but that leaves everything sticky for quite a while.
