So I just bought a delta T3 biesemeyer fence for my grizzly table saw. It’s supposed to be delivered tomorrow. I’m wondering if I should put a sacrificial fence on it. Its not drilled for one so I’d have to drill some holes for it. My current fence doesn’t have a sacrificial fence on it. So I’m wondering what the true benefit would be of having a sacrificial fence.

I have the Delta T2 fence and only use a sacrificial fence occasionally. I bought Rockler’s fence clamps to attach or remove the sacrificial fence easily without having to line up screw holes, or even need a screw driver to attach the fence.

A picture off the web I saw might give you an idea.

I put one on mine yesterday. I just put a new Incra fence on the saw and it had means to bolt one on. I would make one for your fence by building some kind of a box that sat over the fence with maybe set screws on the back to hold it in place. I wouldn’t drill any holes in the fence if I were you.
I wanted one on mine because of making close cuts. I cut a lot of thin strip of wood sometimes.

If making a cut or dado where part of the blade is “buried” into the fence, I’ll use the Rockler fence clamps to temporarily attach a sacrificial fence. I also use them to attach a tall fence when needed.

EDIT: I see bondogaposis beat me to the punch :)

You can also use clamps to hold a sacrificial fence. Here is one example.

Scott,

There are a couple ways I use a sacrificial fence (SF). As hotbyte mentioned, you can bury a blade in the fence if needed. I have rarely done this, but I have moved the fence uncomfortably close to the blade, in which case I installed the SF. My SF is about 6” tall, and provides support for cuts requiring extra high work piece support. However, the biggest benefit for me is the SF gives me something to attach hold down feather boards.

My SF is removable and only installed when it is need. When the SF is not installed, I can use the scale on the fence rail to set the width of a cut – a huge time saver. At least on my saw, I cannot calibrate the table saw scale with the SF installed. That plus the worry about the effect of the added weight to fence keep the SF off most of the time.

alittleoff – thanks for posting the pic. I have procrastinating building a replacement SF, mostly trying to figure what I wanted to do differently. That gave me some ideas.

Scott-I have a Delta T-3 and I use a wood box beam that fits over it with 1 thumb screw clamp on the back side to keep it from sliding. The Rockler clamps mentioned by WoodNSawdust earlier are a good alternative also. I have some Festool type clamps I bought for my Paulk work bench that would work too. By the way I love my Delta T-3. Smooth movement and accurate. I never use a tape measure to check the spacing.from blade to fence.

Definitely nice to have, and you can add t-track, build jigs for it, add a sacrificial face for rabbets, etc.

I like the ideas posted with the pictures of the removable ones that require no drilling. I’d be really hard pressed to drill a brand new biesemeyer fence I paid a lot for.

Thank you all for the input. I’m not going to drill holes in my new fence. I’ll add a removable one instead!

I always try to figure out a way to avoid them…usually cutting the piece a little large, doing the dado then trimming the excess.

+1 on fence clamps. In about two minuttes I made a perfectly usable sacrificial fence from MDF (just cut a piece and drilled a couple of holes), allowing me to bury the dado blade in the SF without drilling into my Sawstop fence.

I picked a pair of Grip tite clamps at wood craft. I used my dowel jig on a piece of oak scrap wood, rubbed some wax on it and went to town. It’s been a great addition to my arsenal.

Quick and dirty solution, 2 sided tape and any old chunk of scrap lumber.
