my build

[irving2008]

Oh I dunno...it depends what load you're applying. For instance...I'm using pairs of common or garden 15 ID 35 OD bearings on my mini-router....zero backlash and well within their capabilities....For machining metals....AB bearings only for me. Horses for courses Irving...after all the MDF router will fall apart before the bearings reach their limit :naughty:

Its not so much the bearings Kip, its the pillow block approach.. the way the bearing locates in the block doesnt give a positive position to the shaft. I'm sure it could be made to work for light cuts, but thats a fairly big router Jon's constructing so I'd assume he's got big plans for it ...

For machining try a drill and an angle grinder equipped with a flap disc in combination with a jig.

I accept no responsibility if you get whipped :D

these are long lengths of TR12, going to need some bearing support on those just to stop the whip, and thats before you put any pressure on with the grinder...
