Topic tags/keywords: miter v27 slot question

I just got the Grizzly 0715P and an Incra V27 Miter. The V27 has to be forced through the rear of the slot. What is a good way to get the Miter slot to run smooth from front to back? I had lubricated the slot, but it still gets stuck, and I don’t think it is the t-slot – it is the channel just compressing against the V27 – even when I have the expanding screws on the V27 tightened all the way – which creates slop at the front channel but still tightens at the rear….u get the idea.

Any help is much appreciated.

Eeek, it sounds like the table slot rather than the gauge. Do you have a dial caliper where you can check the table slot at the front and rear? Have you run a small feeler into the table slot to feel for any rough castings or hang-ups? Good luck!

Bertha,

I do have a caliper and will check it tonight. I am still new and not used to doing these things. I checked for anything in the slot – burrs, rough castings, etc. – and it looks and seems smooth.

Now, what if the slot is off? Is this something I can make do with – can I fix the issue?

Oh man, if the slot’s off, that’s beyond my level of experience. I bet Loren or MedicKen, some of the big tool guys, might know. I’m hoping it’s your gauge, not your table. While you’ve got the calipers out, lock them down and slide them up and down the miter shaft. Check the shaft against a reliable straight edge. Check the floor and walls of the slots again for burrs or deposits (maybe some left-over cosmolene build up?).

That’s a pretty respectable miter gauge and a pretty popular tablesaw. I’d be surprised if either were really that far out. You could make a wooden miter shaft to match your table slot and slide it in and out, looking for binding as a polish on the wood. You can use graphite similarly. I hope you get this worked out.

If the miter slot is not square it is a machining defect and the saw should be returned for an exchange. If so, I would call the famous Grizzly customer service and tell them of the issue. Does the factory miter gauge also do the same thing?

^he heard my call before I even posted that message! That’s a great thought about the factory gauge; does the factory gauge have any slop whatsoever? Does that slop change over the course of the slide?

All – thanks for the ways to hone in on the issue. I have not tried the factory one yet, but will tonight.

I will do all the things mentioned, but hopefully I find the error with the calipers or some kind of burr I could file out. I will update this topic with any issues or the fix.

THANKS!!

If the caliper does indicate that the miter slot is the problem you can probably fix this yourself. Once you have determine which side of the miter slot is off, not squared to the table, very carefully take some sandpaper and sand the wall of that side of the slot until you can slide the miter gauge smoothly along the extire length of the slot.

I have a story on tuning up the miter slots. Since the manufacturers came up with adjustable bars that actually fit the slots closely we have discovered the small variances that happen very often. It really is easy to fix. See the link below.

The link is a pretty exacting approach to take care of the miter slot.

Just have to make sure I don’t overdo it.

The miter slot was tighter at the rear by several thousadths. It was the the left top channel that protruded in towards the slot. I used a file to flatten it out. In addition, the channel itself does get thinner as it travels to the rear by a few thousandths, so I will still have to do a thin wood block with sandpaper to tune it up, but, for the most part, the miter gauge runs along the slot without having to force it past any sticking points. Thanks for the help LJs.

On rifles with a tight place in the barrel they use a plug like a tight swab and some lapping compound to lap it out a little. That works slow but the table is probably softer than a rifle barrel. If you choose to do this on your own then patience is the word. go very slow. I would probably call Grizzly and report to them.
