Just finished it up. Built very similar to the Mike Greene machines but using a water cooled router motor and a VFD to control speed.

Nice!!!! Looks good and solid. Heck I don't know that I've seen a water cooled router. I also like the belt vs the chain I have on mine.


As usual just my $.02

The cost was mostly in time. I was very thrifty buying stuff off ebay, like the Thompson rails and bearings. I have a small fraction of the cost of a new one in it, and LOTS of time.

I am constantly amazed at the talents of some folks on this forum, Very professional looking! Does the stylus scuff up the original as bad as it looks or is it just the picture?

It does tend to scuff it some with a steel stylus, but this stock just had color in the finish so any scratch just jumps out. I need to make a delrin tip to minimize damage but it was not needed for this job as the stock was essentially trash.

Try to look unimportant. Your enemy might be low on ammo.

Then the other question is what did you invent for stabilizers to keep the blanks from moving at all?

I'm not sure I understand your question silvertip1, but the blanks are held in place with 1/4" dowel pins, two in the rear and a single one up front on the center of the axis which the blanks spin upon. The timing on the machine is regulated via a timing belt.

Steve this is his question he asked on another thread.

""What are you using to support that wood while it is in the duplicator? If you look at the Hoenig Duplicator or the photos of the one that David Miller uses you see that those folks pay a lot of attention to making sure that wood doesn't flex even a few thousandths when they are duplicating."""

He is asking about support of a full length pattern and blank in the middle to keep it from flexing.

We just take light cuts. I don't use the machine to attempt a 100% inlet. It still takes plenty of hand work to get a good product.The flex has not been an issue for me in the past.

Steve, nice work. Great looking machine. Did you do any inletting with it, even rough?

Oh yes. We get it pretty close. These are just the first pics after roughing. I'm inletting this stock now(taking a break at the moment) and it has come out quite well.
