Simon Hope Camera System for Hollowing

[dubturner]

Hi,
I seen a demo by Simon at the weekend of his hollowing rig and the camera system. It was very impressive.
I know the concensus on this forum is that the rig itself is good and recommended.
Thats why this post is about the camera. I wasnt able to figure out how it worked.
The fact that the camera was outside the hollow form and yet the cutter when inside it was visable on screen really puzzled me.
Anyone know how it works??
Cheers

Simon will draw the outline of the cutter on the screen when not in the hollowform so that when the cutter goes into the vessel he will know exactly where the cutter should be while he is using it as the camera will follow the cutter wherever it goes, it is mounted directly over the cutter. This way he can hollow out to a mm or two with confidence. -- Julian

Wow!! A really quick reply. Thanks. I seen him draw the cutter outline on the screen, and maybe I'm a bit slow, but cant figure why/how the drawn cutter on the screen moves when the actual cutter moves.

Cutter and camera form a fixed arrangement, so they always move together.When you look at the screen, you don't actually see the cutter moving, you see the workpiece moving. It's the same principle as the laser guide.

I still think the Jamieson rig takes some beating, simple strong and very effective. Less to go wrong and less fiddle factor, Just my ten penny worth.

I'm still deciding on which to go for. It was the camera tat impressd me. The SH hollowing rig seems to get good covereage on the forums but here in ireland I only know two people that have them - one swears by it, the other doesnt recommened it.
Any option is a massive investment so I'll not rush into it.
Thanks again.

The Jamieson rig needs a lot of space, whereas the Hope system is quite compact. Workshops on t'other side of the pond are frequently larger than here, which may explain some of the preferences.

There are a number of systems in the USA with similar principles to either the Hope or the Jamieson, and looking at their websites may help inform the decision e.g.
Sinners Boring Tools, http://advancedlathetools.com/ - a mix and match approach

If cost is an issue, Lyle Jamieson's website gives instructions on making your own rig. This could be done quite cheaply to test whether the style appeals to your methods of working, and then add lasers, fancy cutters etc later on.
Cameras are a different matter altogether, about which I know nothing!

The cameras are sold as reversing cameras for vehicles, they can be bought relatively cheaply if you want to put together your own setup.

Thanks for the info. That might be worth trying.
