Domino Mortise is too narrow

[Birdhunter]

Any info on what part was replaced?

The Dominos must fit very snugly. That is the design. Just because there are some 500's out there that might not be right, doesn't mean they all are. Having used the 500 for awhile, I appreciate the fact that the dominos fit into the slot tightly so that the alignment is always dead-on. If that means I need to scrape a ridge off the edges when humidity is higher, then it's worth it for the result. We shouldn't all suddenly feel our 500's are faulty just because the domino fits tightly in the hole. The subject of this post is an excessively tight fitting domino; one that you have difficulty even forcing into the slot.

You are correct.  This was just a defective unit.  It works great now.
I'm in Southern California so I don't have moisture issues. 

I think there are one or two members that have a similar problem.  I'd recommend sending the unit in for repair.  I'll dig up the receipt and post it.  Thanks to all for your support.

I have both the 500 and the 700. I have to tap in the tenons with both units and with various sizes. I have to use pliers to remove the tenons.

That is a firm fit and that's the same as mine, It's how I like the machine to be.

use sandpaper on the narrow edges

I am delighted with the repair.  The dominos are quite tight as to where you can insert them with your fingers with mild pain.  Pliers are required for extraction.
Here's the parts that were installed the second time.

Great outcome. Thanks for the update.

I think that this illustrates that a cool, calm and almost inquisitive approach to a problem is far better than a pugilistic one. Well done for taking the sensible route and letting Festool handle the issue.

I am glad that everything is sorted out and that your lovely Domino is now in fine shape.

Excellent outcome.  I'm surprised to see that 5 parts were replaced, but it gives me some needed confidence in Festool Service after reading a few other threads that had shaken my confidence.

My DF500 was an absolute game changer for me and enabled new ways to improve my methods (after 40 years ).  Thanks for posting the follow up and now go and have fun with a truly innovative tool.

My DF 500 was making odd-sized mortises and was breaking bits - I had somehow damaged the mechanism that changes the width of the mortise - I guess you need to change it only when the tool is running. Festool fixed mine for free - two years out of warranty. Hard not to be impressed with that!
