Thread: TRA 001 Height Adjust Slipping

Personally I do, as an insurance against something happening like what happened to you.

I also have the TRA001 mounted in my table. Just as I would with a big industrial spindle moulder, I have always engaged the plunge lock before cutting material. The micro winder adjustment winding due to the vibration of the machine when cutting has been discussed on these forums in the past. A simple solution is to set you router bit height, engage the plunge lock lever, then turn the micro winder 'up' 1/16 or 1/32 of a revolution to put the winder bolt threads under tension.

Here's my MOF001 in action. I always lock the plunge mechanism.

Does your router vibrate when this happens?

The extent of the wind down on mine depends on the extent of vibration - some of my bits vibrate more than others and I've had the worst ones checked by a Carbitool supplier and they reckon their O/K.
Bought new collet assemblies and the vibration is a lot less - pretty poor for an 18 month old machine.

Thanks for the replies.

Lappa,
My height adjuster was moving exaxctly like yours in the video, but a little faster. I didn't notice any undue vibration. My router is about the same age as yours, but has had very little use. It's practically brand new.

I'll get into the habit of locking the plunge lock.

Excuse me asking, but I presume you have the plunge spring removed?

Yes, the spring has been removed.

My spring has also been removed.

I had a similar issue and always lock it now.

I found some subtle wear on the main plastic winding wheel teeth, which i replaced. It now works fine, but I still lock it just in case.
I have taken my TRA apart a few times, and I am suprised at the amount of mdf dust clogging some of the internals - cleaning that helps too.

Further to Chrism3, it pays to remove the knob that contains the big lifter spring. It is not needed and fills with dust. I was advised somewhere to remove this to allow dust to be blown from inside the motor.

Next, remove the small black winder handle knob. Its a single screw and pops off. It completely fills with dust and compacts. My TRA was also doing the rotating thing, but solved it by removing the knob. It is unused anyway.

My spring holder knob is off, I had the black winder handle off and no dust. I make all my minor adjustments using that winder knob. I very rarely use the winder handle any more.

Thanks for the tips gents. I will remove the knob as suggested.
