Triton - TRA001 3-1/4-HorsePower 1/2-Inch Precision Router (Rating: 2)

When using the 1/4 inch collet adapter I just cannot tighten the bit securely. I know enough to leave it not quite bottomed out in the chuck and I know that if I tighten it any more it will shear the router away from the mounting plate. The 1/2 inch bits seem to be much more secure. I think the way it is it is a dangerous situation because the bit will 'climb' out from the collet.
I E Mailed the Triton people over a week ago and have gotten no response (yet).
Has anyone else had a similar problem with Triton or other brands?
