My apologies if this has been covered before -- if so, please just direct me to the post(s).

 

I have a coated set of Schneider (Waffenamt kqc) 25x105's that I'd like to finally mount.  The original mounts (a pic of the correct cradle and azimuth base (from eBay) is attached) are even rarer than the binoculars.  The bins weigh about 32 lbs and have the standard German dovetail, which can be replaced with a modern one.  The max width is just under 10".  My thoughts are the 10" and 12" Helix Hercules, and maybe something like a C11 or C14 (I'd have to fabricate the cross bar between the fork arms).  Fabricating one from billet aluminum is a possibility (I machined one for the rare Goerz 90 degree 10x80), but starting with a ready-made mount or pieces thereof is infinitely easier. 

 

What fork mounts do you suggest?

This combined with this should also work although you'll still need a Tripod.

Thanks; I considered that at the beginning but Vixen puts the weight limit of their fork mount at 29 lbs; the binos are at least 10% heavier.  Plus, I'm bothered that they don't give detailed specifications for their products (dimensions, materials, mechanical limits, etc.).  I can't even find out if the swing bracket is physically large enough.  I would think that for a technical/scientific item, there'd be a complete spec. list.

 

I have a 1960s vintage Linhof studio tripod, which was rated to carry a heavyweight studio TV camera of the era.

I use the APM "big binocular fork mount" for my APM 150 BT which weighs about 10 pounds more than yours.  It is expensive, and you would probably want to shim up under the mounting plate to achieve good vertical balance.  It should certainly be large enough and would carry the weight, but would require a very stout tripod.

Thanks to everyone for their input.  I found a 10" Helix Hercules from a member heresmile.gif .  It arrived last night and it's just wide enough, but I'm very glad to have it.  I'll machine an adapter to use a 5/8-11 stud to mount everything to my Linhof R-Stativ tripod, which should be plenty stout.

 

Now that I have the fork mount in hand, it wouldn't be difficult for someone motivated and with access to a waterjet cutter to re-create the mount.  If you sourced the knobs from McMasterr-Carr, all you'd need would be a stout drill press, no vertical mill or lathe needed.
