I bought this for my new watch bench. It is nice but because of the way you work on a watch bench, the lamp is mounted on the same plane as your work space (this is higher than if it were a typical work bench). As a result, the lamp cannot pivot upward enough to get optimal positions.
So, what I had to do was design and print an short extender that pushes the fulcrum of the lamp away from the manufactured pivot point. This allows me more range of motion.
I am pretty happy with how it turned out.
Did a bit more today on my Hettich. I also mucked around with practising on the top plate from the second Hettich that I bought. The calico wheel can leave marks and I am being gentle. I am certainly not pushing the plate into the wheel. I could easily stall the bench grinder that I am polishing on.
I am wondering if Hettich started to use a lower grade of brass? I still cannot polish the brass to a mirror finish.
On my Hettich (older) I have had to emery one of the posts that supports the movement and after 600 grit then 1500 grit, straight to Tripoli on my stitched wheel, then green on the calico wheel and the post is spotless. Absolutely gleams. post has a steel nut on the top of it that was rusty and affected by the battery acid. It is now polished as best as can be done and then I mucked around with a bit of heat and have changed the colour of the nut which looks quite good now. It was black originally.
I have done several jobs now by hand where a having a lathe would have been so much quicker. Have to get rid of the Esprit first. Then I might have a chance.
