« Part 1: Getting Started Part 2 of Visual Hollowing System series no next part

1) Fix the camera to the arm on your hollowing rig.

2) With the power on to the TV, the receiver, and the camera, turn the tuning knob on the receiver to get a clear image.

3) With the cutter outside of the hollow form or bowl, place your ruler or measuring device on the tip of the cutter.

4) On the TV screen, use a dry erase marker to trace the outline of the tool and cutter head. I use a black marker for this.

5) On the TV screen, use a different dry erase marker (I use red) to draw a semi-circle around the cutter tip that matches the wall thickness you wish to achieve.
IMPORTANT: The image on your TV screen will most likely not be the same as the actual size of your cutter and tool. That is why it is important to use a ruler or some other measuring device that you can see on the screen by your cutter when you draw the red semi-circle.

Periodically, I withdraw the cutting tool and double-check the position with the image on the screen. If you get significant vibration during hollowing, the camera can move a bit off target which could really make for an unpleasant end to your hollowing session!

Also, don’t forget to erase and re-draw the cutting tools image any time you change tools.

Have fun and be safe!

Looks like you have a successful setup.
How long have you been using this?
If you don’t mind, how much was the hollowing rig and the laser system?
I’m curious because, I need to know how much debt I’ll be going into!!! ;^)

Ya know….. If you were to do a video….
All anyone would need to do…. is WATCH!!! ;^)

Thanks for all the details and the sharing….

How long have you been using this?

About 3 months, but just a couple of weeks with the Harrison Simple Hollowing system.

If you don t mind, how much was the hollowing rig and the laser system?

Ron Brown’s system is $80 … the Harrison Simple Hollowing system is $150 … the camera/receiver was under $30 on Amazon.

Yeah, I know … I’m just not ready to go there. Sorry!

First off….
Thanks for the cost information.
Seems quite reasonable for such a setup.
Looks like I won’t have to sell a kidney after all!!!

I hear ya, regarding doing a video….
I too, would NOT be comfortable doing a video.
The video “watch” comment was really in reference to “The Captain’s” catch phrase. ;^)

Again, thanks for taking the time to document & share!!!

Yeah … I miss Eddie. I have learned a lot from him. He is on the mend, and hopefully it won’t be long before he is back on YouTube and UStream.

Amazing!
Never seen something like this before.
My first thought were that you could become one hell of a surgeon!
Really impressive, really cool to take use in simple cheap tec to do this – the future are now.
Best thoughts,

Amazing!

Just a little audio-visual trickery! But I appreciate the compliment!

So, I ordered and received a different camera (http://amazon.com/gp/product/B000YM2OIK) and it came in yesterday. I was able to test it out today and it produces acceptable pictures. I’m sure once I’ve gotten it in place on the hollowing system I can fine tune the picture a bit more.

Then, in search of a TV for it I just purchased these from Amazon as well: Headrest monitor (http://amazon.com/gp/product/B007SLDF7O) and a 12v power supply for it (http://amazon.com/gp/product/B006NTNGN0). Those should be in on Friday.

I picked a different camera because I’m a bit leery of items with low reviews. I know that a lot of them are due to the lack of common sense in the people doing the reviews but I’d still rather play the odds.

I’m hoping the 7” TV is sufficient for hollowing. If not I’ll buy a backup camera and use this in the vehicle for what it’s designed to do :)

In the end, for about $50 I have all the pieces I need to try out the visual hollowing system and see if it works. I’ve certainly spent more for experiments that haven’t worked out and all the pieces are usable for other things so I really won’t be out anything if it’s not to my liking.

Thanks for posting this. I’d seen visual hollowing before (it was demonstrated at the local turner’s club once) but until your posting I never really got the hankering to put the pieces together for myself.

Thanks for the update on your progress.

It looks like that 7” monitor has some mounting options. The one thing I might change on my rig is the monitor … it is an old 17” flat screen TV that I put on my bandsaw table about 5 feet away. With the monitor you are using, I might be able to mount it right above the headstock on my lathe.

Keep us posted!
