>Gary,

I have not used it, but I understand Lyn Mangiameli has written a review on it. I'm not sure where to find the review though? If anybody knows where it's hiding, could you direct us to it. I'm curious about this system too.

Thanks,

Jennifer

>receive. At least this time.

I still have a full review in the works, but here is what I wrote for Part 4 of my Opinionated Survey of Hollowing Tools.

Donald Derry: [Available direct from Donald Derry via his web site] This hollowing system is almost unique in that it is intended for use with either forward or reverse spindle rotation. Excellent laser stability and smooth, fine x-y axis adjustment (though slow to set); perhaps the most precise laser system available. The system�s smaller size and relatively light weight make it convenient as a hand held caliper as well as a hollowing rig. The overall system is restricted in capacity to about 7-8 inch forms, and at this time is limited to only a single length straight shaft with an off axis cutting tip style which is CA glued in place at an approximately 45 degree angle to the shaft. This makes it more suited for tall slender forms than squat fat ones. Derry intends to eventually introduce a curved shaft which should increase the versatility of the system, and I am presently using a prototype of what may become the final curved design. The sturdy gate allows for interchangeability of post size, and can be ordered in a variety of post sizes. It can be modified to take a Clevis pin to make it into a pin rest as well as a restrained gate. Put a hardened sleeve over the distal bolt threads and you can use that as a large pin stop. With a change in bolt and spacer length, this gate can also be set up to restrain 3/8, 5/8 and 3/4 inch square tools shafts (such as the Pencil Stingers, Lea and BCT). Remove the upper bar and you have a flat heavy duty base that can function very well as a box scraper rest or with a fluted parting tool, making it an exceptionally versatile tool rest/gate. Like with most hollowing tool rests, this one would benefit from a shaft collar that allowed a consistent height to be maintained during replacement and when turning the gate, but this can be inexpensively added by the user. The included 12 inch long (12-1/2 inch working length including tool bit), 1/2 inch square tool shaft can be used without the gate or laser as a free hand tool. The entire system is very well integrated and balanced between its components. This may be the simplest to set up, easiest to use and most affordable restrained, laser guided hollowing system available and is especially suited for those who are new to hollowing or wish to have a system particularly well matched to smaller lathes.

A full discussion of almost every restrained hollowing system is in Part 4 of the Survey that can be obtained at the link below.

>I can't compete with Lyn's review, but I am a very happy customer. I've got Don's laser hollowing rig, and love it. I also have his small hollower for small turnings, and for my smaller turnings I use this exclusively. I highly recommend his tools.
