Brocock S6 Fill Probe Dimensions

[int3man]

Hello and Help.  My shooting bag was stolen along with my fill adaptor for my Brocock Super 6 XL .  So I need dimensions so that I can machine one.  Thanks in advance for any and all assistance!

Edit - I can't remember if he's on the GTA or not. I've forwarded this thread to him and will reply if he sends the specs to me.

Thanks, Brian.

Let me get the probe out of my kit: This is for an S6 series gun?

Brocock Contour S6

OK, I dug it out and measured it. I have 3 Brocock Probes (4.5mm & 5.5mm Contour Elites), and one for a Compatto Target (4.5mm), but that probe looks like it was salvaged from an 80 year old shipwreck (Thanks AoA, you tried...not very hard  ).

I'll get the blueprint uploaded, but the lowdown is this:

Probe O-rings: AS568A-008 Durometer 70 (3/16" ID x 5/16" OD x 0.070" Yes, I know it's not metric, but this is what The Brothers Silcock use.)

The Stock Probe is machined from 12mm brass Hex Bar, and threaded 1/8" BSPP for a hose or fitting. If you are having one made, a machinist might balk at that thread. Here in the U.S.A., 1/8" BSPP is a rare bird in machine shops (9.6mm/ 0.378" OD x 28 Threads per inch with a Whitworth 55 degree thread form.)

Taps and Dies for 1/8" BSPP are commonly referred to as G-2 or G-02. Hydraulic Shops will be familiar with BSPP/Whitworth threads, but the 1/8" is unusual nowadays. Many old pressure sensors from British and older Japanese cars (Datsuns especially) commonly used this thread.

I would recommend using a 1/8" NPT thread to keep it simple.

Root: Reference Dimension -A-
Probe Length overall: -a- 28.0mm/  1.102"
Major Probe Diameter: -b- 7.42mm/ 0.292"
Minor Probe Diameter: -c- 6.25mm/ 0.246"
Minor O-Ring Groove Diameter: -d-  4.75mm/ 0.1875"
O-Ring Groove Width: -e- 1.75mm / 0.068"
Minor Probe Diameter Journal Length: 4.0mm
Minor Probe Diameter Journal Position: Starting at 15mm/ 0.591" from Root of Probe, ending at 19mm/ 0.748" from -A-
                           Alternative Position: 2mm to either side of Probe Outlet Cross Drill Location
                                 Feature Callout: Both sides of Journal Chamfered/Bevelled to Major Probe Diameter at a 30-45 degree angle.
   Recommended Method of Technique: Using a 60 degree Threading Tool, plunge cut and turn.
Probe Inlet 3.0mm/ 0.118" x 18.5mm/ 0.728" Deep from -A-
Probe Outlet Cross Drill Location: 17.0mm/ 0.669" (one side only)
Probe Outlet Diameter 3.0mm/ 0.118"
Inner (Root) O-Ring Groove starts at 11.0mm/ 0.433" from -A-
Outer (Tip) O-Ring Groove starts at 23.0mm/ 0.905" from -A-
Tip Chamfer/Bevel 0.08mm/ 0.031" at 45 degrees

Material: C360 Brass

I'll get the blueprint uploaded, but the lowdown is this:

Dude - you keep posting like this and I'm gonna nominate you for NASA member of the month!

check this place out.  i ordered and received an o-ring kit, 10mX1 to 1/2X20 muzzle adapter, magazine indexing claw, and another magazine from them a couple of weeks ago.  came in the mail rather quickly considering it's from across the pond.

Wow Thanks!  That is great I await your drawing.  I think I follow but I need to see where Axis A is.  I was planning on 1/8 npt as I have a die for that.  I just got the saddle repaired on the lathe this weekend.


BSPP and BSSP threads I'm familiar with.  I built Wheelchair lifts for Buses for 30 years.  I did the Hydraulics.
Thanks again.
