Default anti-kickback fin only for off track?

Hi all,
I finished installation of the EZ Smart base to use with my track after using a handmade base for running my saw on the track for the last few years. Installation went off without a hitch and the saw has been working well with the new base. I really appreciate having the anti chip edge on BOTH sides of the blade now. One thing I didn't quite realize when watching the base installation videos was that the anti-kickback fin doesn't reach down into the kerf when running the saw on track. This makes sense as it seems less necessary when running on the track, but I want to make sure I didn't screw up something during installation. Is this right, the fin is only needed for off track work?
thanks,
Dan

Don't need it if the wood is flat. It's only for when you're cutting vertically up against the wall like a panel saw, where the kerf can close up on you and turn a good day into bad

My understanding is that it should enter the kerf when using the saw on the track.

Fin sticks out the bottom of the Base 3/8", the saw track is 1/2" thick. So the Fin won't engage in your wood when using saw on track.
Don't think I understand what's up with the Fin. It seems to me what cutting stressed wood could result in the kerf closing whether cutting on the track or off, it does for me anyway. So you'd think you'd want the Fin to work in either case.

The fin has been indispensable for me with the UEG, especially when ripping pieces dimensional lumber. For on-track use, a longer fin would be useful if using long lengths of track. With the EZ1 or other PBB it is likely not necessary due to most cuts being less than 48".

The fin does not align with the kerf on mine.

Use a straight edge ( clamp the straight edge to the fin and blade)
and re-install the smart base.
You may have to make new holes or enlarge ( oval)
and use the screws and nuts.

Default Distance from Slot in Base to Blade

What is the expected distance from the groove in the bottom of the saw base to the inside face of the blade - this would be the distance from the edge of the groove to the tips of the fingers in the base that are used to install the saw in the correct position and with the blade parallel to the groove?

Thanks for the info.

Easier said than done.

Thanks, Dino, sounds like great ideas for this base. However, this particular base has been a problem since day 1. My second base was no problem, but this one is kind of warped, it eventually cracked at the one UEG mount point. At this point I am just happy to have it attached. I figure I will use the makita with the o other base on the track, and if I can get some epoxy to hold the crack together, I will use this one for the UEG. I was trying to use this on my Bosch CS2. The other issue with the fin is that it won't allow the blade guard to move. All in all, if not for the second base and the experience with the makita saw, I would have abandoned this system as unusable a long time back.

Spending another $50 on a base seems like an expensive experiment since I am already at 50% success rate on them. Unless I find someone selling out a bunch of used stuff on the cheap I may try to make one from MDF or plywood or something.
