Brett.
I try to please. As to the tumbler idea, in another lifetime, I did once polish gemstones (lapidary). Using junked autoparts might be one of two things, intellectual laziness or inspired genius. The washing machine pump motor comes from a Hoover Premiere, the original fitted. The replacement is an altered design. Once I get the polishing trick sorted, I want to use the tumbler with small loose bearing balls and dry 5 micron powder or 3 micron if I can find it, to attempt to create a finer frosted glass surface, ie., light contact pressure, hopefully a stamping action instead of a scratching action and hopefully a finer groundglass. |

FYI I just took a normal cd-r NOT the spacer type and sanded the top layer off...now it's a better then spacer-type GG because the cd-r is a higher quality then the cd-r spacer! I took my small orbit sander and did away with the top coating..works great

glidecam
just took a quick look couldnt find any previous answer to my question so here it goes...
Im shooting a movie this summer with the static lens attached to my camera, i would like to use it in conjuction with a glidceam, has anyone done this? I do not have the glidecam to test right now, but i was wondering if the added weight to the front of the camera made it impossible to do. (obviously i would need to counterweight it in some fashion, but with all this additional weight it makes me think it may make it extremely difficult to operate) Any thoughts much appreciated. Thanks Pat |

If you are using the hand held version I would start working out. It is not for the out of shape.

1500 grit actually isn't as fine as it sounds. This webpage provides a grit-mesh-micron conversion chart that shows how 1500 grit is only about 10 micron. Many users have ground their glass with 5 and even 3 micron (equivalent of 4500 and 8000 grit) and can still see grain using a static adapter and standard definition camcorder.

Obin
Sanding off the top layer. That option works fine except for the disk having a green tint which has to be manually white-balanced out. Not a big deal but it is there. Pat. You might examine finding the new centre of balance point with the Camcorder/Aldu assembly, then getting a piece of 3/16" aluminium flat bar, for fastening to your camcorder's tripod bolt-hole, then drilling and tapping a new threaded tripod mount hole and keyhole in the flatbar at the new point of balance. This also may enable you to also get a better lateral balance point. Some cams have tripod mount holes offset to one side. |

Pat I have shot with our steadycam and the mini35 on the front that I made with the spinning cd works great BUT you need a focus puller to get any good shots at all unless you dont move aobut much and shoot the subject the same distance from the camera the whole shot

WOW this is one of the longest threads I have ever seen. I was trying to search through the post but there are just too many. What I am looking for is instructions. If any one has a step by step how I would love to see it.
Thanks in advance Michael Moore |
