First off, I am new to this site and this is my first post. Looking forward to exploring the galleries blogs and videos.

I’m hoping someone can help with my Dewalt 735. Let me start by saying I hate this machine. It has broken my heart and my wallet. Like most everyone else who purchased this planer, I was appalled at the quality of the stock blades, so I upgraded to the carbide blades. After the second sharpening the hold down screws were hitting the stock. I complained to Infinity and they generously sent me a new set. Before I sent the first board through one of the hold down screws broke off and shattered all three of the blades. Utter dejection and colorful language ensued.

After much agonizing I decided to upgrade (?) to the Shelix. Even taking very light cuts, the motor bogs down almost to the point of stopping. I can get good results (the quality of the finish is very good) but it takes many passes to get there.

I understand that the Shelix head is smaller in diameter than the original. What I suspect is happening is that for the cutter to reach the board the feed rollers have to compress and apply a lot of pressure thereby draining a lot of power. After installing the new head, the depth of cut indicator shows me taking a much bigger bite than I am.

My question is this; does this make sense and is there any way to adjust the feed rollers in relaltion to the cutterhead?

Any help would be much appreciated.

I don’t know anything about the Shelix head for this machine (my 735 has the original head)—but I don’t think you should have been disappointed that ”after the second sharpening” that the blades were too narrow to clear the hold down screws.

This machine is designed to use disposable blades. They are intended to be replaced, not sharpened.

I had a 735 with infinity carbide tipped blades.After the second sharpening I left off the hold down bar and used a washer with the torx head screw.I also sharpened them many times.Its a fine machine maybe if you disconnect the fan motor and use dust collection you can make up for the loss of power.Thats all I got.

I have the shelix head in a 735 and have no problems with power. I do run it on the slow speed I pull off 1/32 to 1/16 on maple, walnut, purpleheart, paduak etc. with no problem.
I would guess you have a problem somewhere else.
