PRACTICE CAGE for DV

Yep, countersunk the holes for the 1/4-20, but i didn't CS the holes that were holding in the 4 posts. So when I went to slide it in my EFP top stage, I had to remove the cap screws from the bottom front of the ccage, then replace them once it was on the top stage.

 

aside from that, it worked great. I might try to drill some more holes in the top, and bottom of the cage, hopefully to reduce the weight just a tad. It's 18lbs now, and I'd like it to be 15.

 

Thanks for the help everyone.

Just don't go too light as the arm has a minimum around 15 lbs... My practice cage is 22lbs and when you add an XL-1 it's about 29lbs total. Also, the EFP/3a arms are reported to behave more neutral when in the middle of their adjustment range, so the heavier the camera (to a certain extent) the less "springy" the arm feels.

 

Besides, I'd always rather be on set and have my rig LIGHTER than I practice with... Helps build confidence and stamina, and when on set you'll be able to concentrate on everything else instead of the heavy rig.

Yesterday I discovered another good reason to use my cage for those lightweight (H)DV-cams: I had a Sony HDV on it, with 2 radio-microphone receivers attached (plenty of room for that) and suddenly the director decides to do a shot fom one Tuk-tuk to another.....

 

I was happy that that steel cage was around that poor plastic camera or it would have been severely mangled in the making of the shots...... :)

 

And not a scratch on the cage so I can still sell it ;)

In an effort to recover from my crane accident, I am in need of a heavy practice weight for my sled.  If you are in the Los Angeles area and have a weight I can use for a couple of weeks, please send me an email rigflyer@hotmail.com

 

Thanks

Bill, I'll bring mine to the set, when you come to get your gear you can

pick it up.

And as I mentioned the other day when you stopped by and flew my rig...

you can fly my rig again anytime if need be...even though they won't let you do a shot.

By the way, my weight cage is about 22 pounds and I have other weights that

can be added to bring it up too. Call me and let me know.

Greetings,

 

I just had my local machinist run off a practice cage for me. I think it came out pretty nice. Take a look:

13.25" x 5" x 8.5"

30lbs

 

For anybody that might be interested, I paid $210 for a run of just one. If there's enough interest, I'd put in an order for more. The greater the quantity, the lower the price.

 

Rob Van Gelder has made some, and I know he has at least one in stock.

Mike O'Shea has said he will also be making some more in the very near future.

Very nice Afton!

 

Now get it powder coated...unless you like that nice orange hue on everything.. :P But if so, get them to paint it that colour...

 

Also, you may want a couple holes on the top piece. Perhaps, also get a duplicate of that top piece that is half thickness (1/2inch? 7.5lbs) so that you can weigh in with a little less weight. Also that reduced weight is just enought so when you have a heaver dv cam..xl or whatever, with FF and Accs, it will still weigh in at about 30lbs...

 

The first one I made was 30lbs, but I have since reduced it to 22ish.

 

Again it looks awsome!

I only had one plate drilled to save time and money. For low mode, I have a low mode cage, and I figured if it was too light, I could always add just the one drilled plate to the low mode cage. I haven't yet tried this, however, so if anyone knows now that that is not a good idea, please share.

 

My machinist could've treated the metal for an additional $80, but he suggested I just do it myself with some primer and sealant that I can get at any hardware store. As I understand it from my experience with my motorcycle, powder coating is not cheap, but if there are different degrees of coating that I am not aware of, again, please let me know. I would imagine the look of one's motorcycle is a bit more important than that of one's practice cage, and therefore the process would be slightly more involved.

 

Thanks for the comments and help!

 

Best,

Afton

Nice!

 

I just do not understand how you attach the camera to it, the holes are quite deep according to the plate thickness. do you have some sort of special camera screws to attach it?

 

maybe you could do sthg. like in my picture.

 

and why are there threads in the plate? for fixing the cadge to the dovetail plate?

 

greetings, robert

The camera is attached via the counter sunk (conical) holes - similar to your picture. A regular 1/4" x 1.5" screw is run through the weight plate and into the camera. The counter sinking allows the screw to be flush against the bottom of the plate. Then, the dovetail is placed on the bottom of the weight plate (which is why it's important the camera screws be flush). 1/4" or 3/8" screws are then placed through the dovetail into the threaded holes and everything is all set. The threads allow the dovetail to be secured without the use of nuts and bolts.
