First, Tony Karol PM'd me with a little warning about the fret saw baldes we all got a few months back. He has a unisaw (as I do) and reports that the blade can fall into the 'valley' of the threads and result in the blade not being centred. Imagination can tell you what that would like and it may also come up with some ideas for the small section you just sawed off your fretboard! So I thought I would mention this so that you do a test cut before you commit you good fret board.

Second, In the process for getting ready for GAL I took a bunch more photos of my process of processing tops. Is there any interest in having me post the rest of the process?

Thanks

Shane

Well, actually I'd love to see the rest of the process...but if I'm the only one, don't post all of those. It's a lot of trouble. But the earlier stuff you posted was great, really.

Ok, I should have it up by early next week. Thanks for the interest, I am glad that I am not the only one that digs the process!

This happened to me on my unisaw with a brand new blade I bought at lmii a few months back. I noticed the wobble in the blade before I cut so I didn't ruin a fingerboard, but, I ruined the blade when I tighted the arbor nut--it clipped the arbor hole of the blade.

I called lmii to ask why there wasn't some sort of warning in the instructions and they said they had never heard of this happening before, they thought it must be unique to my unisaw or something. Anyway I had to buy another blade.

Any ideas on how to remedy this problem, I have a Unisaw as well. Just make sure the blade lands on a thread?

I like LMII, but I bet Stewmac would have given you an appology, and a new blade.

I just went into the shop to see what can de done to stop this from happening, and you guessed it, it doesnt really want to do it this time !!!! I think it really depends where in the rotation the arbor has stopped, and I will bet that it probably might only happen one in 10 times or something - no matter what I did, short of forcing the blade into an adjacent arbor thread, the blade sat in the correct spot. So the arbor happens to be solid, ie - there is an outer portion of the thread, not the groove, sitting up, and the blade sits nicely on it.

So every time you load the blade up, check to see if it naturally wants to sit down in the thread once the first stiffener and the blade are on - then add the next stiffener and tighten the nut.

I don't know but could it be that just one stiffner disc is used instead of two, could 2 stiffner dics prevent this from happening?

Serge I think you would always want to use two stiffeners. It'll likely mean that you need to make a new zero clearance insert for your table saw.

Right Anthony - I just raised up to cut a new slot in mine... you cant use this blade reliably (or possibly even safely) without two stiffeners - especially the kind that are the hollow plate style, they have to be used in pairs - only the outer most 1/2 inch of each stiffener touches the slotting blade. If you only used one the blade would be forced into somewhat of a bowl shapewhen you tightened the arbor nut and likely wobble then break. The Forrest style is actually a flat ground plate

It only happens when the inside stiffener is in place, this puts the blade out on the threads, and the arbor is turned so that the blade falls between threads by gravity.   After the inside stiffener is in place make sure the arbor is turned so some of the blade is on the thread. Put on the outside stiffener then gently tighten the arbor nut, if you see ANY space between the blade and inside stiffener, stop tightening. If you hear a click, it's too late.Marc38898.6592592593
