My plates are slipping inside my very well used DB2.  I went to do a drop time test and when the camera came back up it was tilted down.  So the plate slipped forward.  I put some gaff on the smart side of the plate where it locks down against the clamp, which seems to be the only point of contact with plate on that side.  That helped but last night even that had just a tiny bit of slippage during a prolonged take of tilting straight down.  

 

The clamp with the 5/32 screw seems to be bound up.  Whereas I used to be able to push it back and forth when loose now it doesn't move.  At this point it is still very functional.  And its a bit annoying having to deal with the worst case scenario, in my mind, as I try do what it do.

 

Hope this makes sense.

If screw is 'bound up' its obviously not holding clamp device tightly any longer right?

Figure out how to back it out without ruining the threads and replace the 5/32.
If the clamp is not moving a drop of oil on the clamp could solve your simple maintenance problem that has finally shown up as slippage of your dovetail.

Make sense?

DB2 here is not locking down fully with all plates.  Actually it is your old DB2 Janice!  Doesn't seem to be an issue with the clamp screw, any other thoughts before I dive into this thing?

PRO plates are slightly wider than tiffen and some third party plates and the db2 cant tighten down enough for the slimmer plates. The db3 fixed this as it can tighten down more. Some carefully placed tape seems to work for some people on the db2.

Isn't locking down on all PRO plates either.  Have a pro longplate that slips on it.

I'm thinking the problem is this silly little latch

 

I cleaned up the gunk build up that was between the stage and the tightening mechanism and that actually helped an enormous amount, but there is still a small amount of slippage.

 

The latch is just...really old and worn out I think.  Is there any replacement available anywhere, and specifically one that is maybe a millimeter deeper on the connecting side?  For whatever reason Pro designed this mechanism such that there is almost zero tolerance

Ive been thinking about making up some new ones that add a little thickness. Right now mine has a piece of gaff tape on it so that it will tighten down tighter.

Pro charges $200 for a new lever

 

That's a tough buy for a lever.....what do you think you would charge if you made some

Does PRO have db2 levers that make it compatible with all plates? If so wouldnt bother. Not sure about price, should be less than that. Might get rid of the lever and do a bigger clamping surface. Either way its going to be a little bit since I have other projects to finish first.

PRO only makes one style of db2 lever and it is only made to the tolerance of the original lever.  I was told that there is only the one option and no guarantee that it will tighten to third party plates.

Hi all;

My dovetail plates eventually were so worn that they were dangerous.

I found XCS plates were a much tighter fit and much more rigid.

They also hold follow focus rods very securely.

Really changed the way I attach a camera.

They were $ money but boy did they work.

If slippage is your issue and the lock is hard to replace this is an off the shelf solution with other perks.

Have a good, busy season.
