Like the title says…
Two of the guides fell out of the lower guide block assembly today. Of course Laguna won’t answer a phone call on a Saturday…. if at all…

Has this happened to anyone else? If so what was your fix?
I thought about using epoxy to put them back in but was worried about replacing them in the future.

What are your thoughts?
Thanks in advance

I’m not sure I understand correctly, are you talking bearings or cool blocks?

I pulled up the Laguna manual, the image they show for the lower block, (pg 35) looks similar but I found no instruction for changing the ceramic, only that they must be just behind the gullet. without actually removing the block and disassembling it I’m guessing the ceramics are the dark grey 1/2 circles and sit inside the half round rings either side of the band. Is it possible the side guide screws got loose, pulled away from the band enough to fall out?

The little white pieces in the picture above are the ceramic guides.
2 of those have fallen out.

?I knew that, ... I was just testing you┬┐ Well then I’m even more confused. So what’s the grey thing in the middle? Can you pull the white things out without fuss? Do they shoot out the front of the block during use? Are there no covers? The 14/12 manual does not show the view you have above, looks like covers held in place by 2 knobs.

Sorry can’t help here my SF 1707 used bearings

At the risk of never getting them out I wouldn’t attempt to glue them in. I would hold off till I got a hold of Laguna and got some kind of answer.

If you epoxy them in how do you replace when they wear out. I assume they wear out.

They are held in place from the factory using gel super glue. I wouldn’t use epoxy.

Cheers,

Rough idea on how often the guides need to be replaced? Can the saws be refit with guide bearings?

When the guides wear out you’ll have to buy a new saw. Come on guys…

It is very hard to answer that question since there is no way to account for all the varied conditions different users subject them to. Suffice it to say they last a very long time in “normal conditions”. Stoning the back of the blade helps keep the thrust “bearing” from excessive wear, most people seem to find they are the first one to go. IIRC the cost of a set of inserts is about $80 and will outlast the standard small bearings on most current bearing type guides by many times and will likely be more cost effective than bearings (again small bearings) even using the large number of cheap bearings out there. The Laguna (and Felder) ceramic guides tend to be a love ‘em or hate ‘em sort of product, I find their positives significantly outweigh their negatives is most situations.

After reading that you have Timberwolf bandsaw blades for half a decade that aren’t worn out I would say at that rate of use you would be unlikely to ever wear a set out… :)

Have your say...
