BandSaw Modification for a Streching Belt

This model of BandSaw seems to have stretching problem, probably do to it's 3 wheel configuration,

So this is like a secondary saw, Don't want to spend any thing on it at the moment,

My solution is to had 2 pulley, both made from 4 Rollerblade bearing, This model has a wide Belt,

Drilling 2 hole in the cast iron casing, did not hurt it at all, :)

So I need 8 bearing, That's one pair of used Rollerblade, (Yard sale)

2 long bolt, and some washer..

That's it,

Drill and ratchet, :)

Tank's for watching,
