Hacking the HVX weight for Steadicam Merlin use

Using the Steadicam Merlin with the HVX200 is a challenge. The camera's stock weight is outside the recommended weight for the Merlin. In fact, it won't even balance on the Merlin at all in its stock configuration.

So far, I have read about two ways to make these devices work with each other:

1. SMALLER BATTERY. By using the medium (2800) battery instead of the stock (5400) battery, the HVX200 total weight just edges into usefuleness. It is still over the recommended weight, but this technique appears to have been given a wink and a nudge by Merlin designer Garrett Brown.

2. ADD NEW WEIGHTS. By adding weights to the bottom of the Merlin (whether washers or by ordering one or two Merlin weights from Tiffen), weight under the Merlin can balance the stock weight of the HVX. This technique is not recommended by the manufacturer -- there is apparently a greater risk of damage to the fragile gimbal by adding any extra weights.

I plan to stick with #1 as long as possible.

Here's the thing: I just weighed the stock battery and the medium battery on a postal scale. The difference is only 2.5 ounces. Thus, the goal appears to be "Stock Minus 2.5 Ounces." That has to be achievable in a number of other ways.

Also, the Century .6 wide angle converter only weighs 9 ounces -- so if 9 more ounces can be removed from the camera, that will allow use of the converter. For me, this is a huge benefit. Wide-angle + Steadicam = awesome.

Oh, and the lens hood weighs 4.1 ounces. Since that has to come off for the wide-angle adapter, that leaves a difference of only 4.9 more ounces to remove (starting from Stock Minus 2.5).

I've been looking at my HVX like a butcher, wondering what parts can come off and how much they weigh. (Yes, I know removal of some may void the warranty.)

For reference, here's a list of parts and what they weigh on my cheapie postal scale, in ounces. I have left blank the parts I have not weighed yet (the ones that don't come off easily by hand). Anyone already know how easily these parts come off? Any others to put on the chopping block?

  • Regular 5400 Battery 9.5 oz
  • Medium 2800 Battery 7 oz
  • Century .6 converter 9 oz
  • Lens hood 4.1 oz
  • P2 Card 1.8 oz
  • Rubber Eyepiece Cover 1 oz
  • Strap
  • Viewfinder
  • Handle + Mic
  • Cold Shoe Mount
  • Small 1800 Battery

(If possible, I'll keep this list updated here in this first entry for easy reference.)
 
what is the price difference between the merlin and a steadicam that supports the hvx+more wieght?

About -$400 from what I can tell.

The meril seems to go for about $800. While other supports like the Glidecam 4000 Pro goes for about $400. And it seems that the G4P will support the HVX just fine. (This is just bases on a quick search that I did on the net.)
 
Hmm, interesting stuff here.

Don't foget the effect of vertical displacement of component. The higher a mass is on the camera, the more effect (leverage) it will have on the balance of the rig.
A P2 card in the bottom slot is better than a card in the top slot for example.

The only other thing that comes to mind that could be moved off the HVX is the battery!
With an suitable external power supply - ideally a battery holder on a cable - you coudl move teh HVX battery down to the bottom of the Merlin - for example onto the Merlin Accessory Plate (http://www.jimfarrell.com/merlin/) That would free up a few Oz. up top for a WA or a filter or 2.

- Just be sure not to use the Plate to add any extra weight (more than the regular counter weights), bceause in deed you don't want to compomise the strength of the Merlin.

Cynic has a point. A much better Steadicam for the HVX with accessories is the Flyer. But the Merlin does a great job too.

Thanks, Mikko. Great advice. I hadn't thought of that.

Stock Minus 2.5 makes the Merlin usable, but it still wants to be a little more bottom-heavy. Any little improvement helps.
 
When I tested it for a review, we used a much lighter battery and no accessories.

Took a while to balance, but produced some incredible footage.

But more than a couple minutes is a little dicey.

Can someone please tell me the actual weight of all the weights that come together with Merlin? thanks
 
I have seen the HVX200 on a merlin at a trade show, setup by tiffen staff, working fine. Im good freinds with him, so will find out what the deal is...
