Nice! I don't think I'll be taking my RT apart any time soon?? But if I do I have a full guide right there since it's exactly the same :thumbup:

Now I'm gonna say it and this is before I hit the old Goggle button.... What's an oldham coupling? (apart from a rotting pork joint :lol: )

Now back to serious.... Oilite bearings. I knew they were sintered etc but did not know about their machining. Do you ever need to re-impregnate them with oil? If so.... How? What with? Well someone was probably going to ask? Thought it might as well be me ::) :)

Liking the return to the Tuit list :thumbup:

I have never had to repack oilite bushes, so I wouldn't know. As far as I am concerned is that they are classed as lubricated for life. That is why I took it so steady when machining, I didn't want to lose or contaminate any of the precious contents.

Supposedly they can be repacked by boiling in an hard setting grease like Linklife, used on mo'sickle chains. But I have never done it. They are cheap enough to replace anyway.

John,

Great work there, interesting post this, thanks. Shame about those threads - a bit of thought by the manufacturer and that could have been avoided.

On the subject of oilite bushes, where do you get the oilite material from? You may have said but does it come with an accurate bore? I have 2 jobs in mind for some.

Thanks

Nick

AFAIK you don't buy the material. They come ready made. Comme ca ..
