My Excalibur EX-21 Died

[BadBob]

About two weeks ago, my EX-21 stopped while I was cutting a made-to-order project. I switched saws and finished the project. Yesterday I got a chance to start working on it. It had to be something electrical, so I began testing at the power outlet and worked through all the electrical parts. Everything worked as expected. The last thing I tested was the motor, and it was OK, so it had to be the controller board. I replaced the board with an old one I had, and it is back online.

While disassembling the saw, I realized I needed to be careful with the plastic parts because if I broke one, I might not be able to get another one.

If a plastic part breaks, check at a local high school or university.  There may be a shop/engineering class with a 3d printer that could recreate the part for you.  

In fact, that same school may have an electronics class that may be able to repair your control board.

Depending on your model, I suspect most parts on the King would be interchangeable or maybe even Pegas.  I have the green Taiwan version of this saw, and so far, only thing I've had to fix were the clamps, which I upgraded to Pegas.  (I also have a 16" King). 

I've always been a little leary about the complexity of these saws, at least the mechanical side, and I am hoping my luck holds out and I don't have to deal with any serious repair.   I do treat it with care,  and leave any abusive (thick) cutting to the Hegner.  For me personally, I would rather "drive" the EX, but I was able to do a serious repair (broken drive connector) on the Hegner, and would freaking hate to try that same repair on the EX.

It's not that big of a challenge. I have had this one apart three times now.

I would probably us JB Weld or something similar.

A new board costs $82. To me, repair is not worth the effort. I could do this myself if need be.

I'm not familiar with an EX 12. Could you post a pic of your saw? What is the vintage?

Ray, I think Bob corrected it in his post EX 21, RJ

I'm not sure what you are seeing, he never edited his post.. The title still says EX-12 on my end.. But I believe he just did a typo..

I fixed it. I have a nerve issue in my left arm that causes some of my fingers to have delayed reaction times. This causes me to make many transposition errors when I type. Grammarly usually catches and corrects these errors, but it doesn't work in the post-title space.
