I know this is 3 years overdue but we had our Canadian Long weekend so I finally made some time to write up my build thread to you guys who have been asking. Here is the step-by-step write-up. Thanks for your patience.
Needle nose pliers
Philips precision driver
Hand Tap 6-40
WGP Trilogy Select Fire Grip Frame
1/8" Stainless rod
LPR Hose barb 10-32 x2
6-32 socket head screw x2
6-32 fiber lock nut x2
Disassembly of the Grip frame
Remove the grip panels and unplug the 3 wiring connectors from the board
(Switch, Eyes, Solenoid)
With a Philips driver Unscrew the following
3 mounting screws from the board (54-401 2mm, Length 8mm) Ping me if you lost them
2 screws holding the Solenoid micro switch
2 mounting screws from both sides of the Ram-solenoid assembly
1. Wiggle out the board then the Ram-Solenoid should slide down
2. Take a Centre punch knockout the 2 knurled pins holding the Trigger and 3-way plate
3. Before Knocking out the knurled pin holding the Sear, Loosen the set screw
holding the 3rd pin
4. Remove the trigger internals and put them aside
5. Separate the Ram-solenoid assembly
6. Extract the Delrin piston (white) from the Ram by Blowing Air into the bottom of the Barb/hose.
7. Carefully unscrew the bottom Barb from the Ram and put it aside. HEAT the barb first to soften the Locktite or it will snap!
Preparing the Mini Ram
1. Using a No. 31 bit, open up the lower bottom hole on the mini Ram Body.* Do Not Drill all the way through.
2. Using a 6-40 UNF Tap the hole. Debur and Clean out the Ram.
3. Reinstall the Barb into the new hole with a blue locktite. A drop of oil on Delrin piston and re-mate it with the Ram
Preparing the Grip Frame
1. Drill the hole in the frame for the trigger pin
2. Align the drill bit No. 31 (or 9/64) to drill through the trigger guard (59.9mm) from the top & 6.5 mm from the bottom edge of the back slot.
3. Center punch the marks and drill through the trigger guard first.
4. Pre-drill the back hole providing the proper drill alignment & drill all the way through from the trigger guard.
1. Cut & shape a small piece of Plexiglass (or plastic or wood) to fill the back slot in the grip frame
Dimensions: 10.1mm x 20mm 6.2mm thick
2. Fit the piece in the slot of the trigger frame and mark & drill (No 48) 2 holes for the mounting screws (which held the solenoid).
1. Place the Grip frame over the Aluminium plate and trace the profile of the opening. Cut the plate and test for fit.
2. Cut a slot in the leading edge of the plate so to allow space to slide in the Ram and to prevent interference & rub with the swing arm of MSV2
3. Mark and drill the holes for 2 screws (top & bottom) and mount the plate.
Cut a 1/8DIA Stainless rod to 23mm long
1. Reinstall and lube all the trigger internals
2. Reinstall the Ram with the 2 mounting screws on each side
3. Insert the trigger pin in the hole from the inside of frame
Test the the MSV2
1. Install Marcroline from the Ram Barb to the OUT port of the MSV2 (Left hole)
2. Connect a external LPR to an air source and run a Macroline from the LPR to the MSV IN port
3. Pressurize the LPR and cycle the MSV. Do NOT exceed 70psi
Alignment of the MSV2
1. Place the MSV inside the frame aligning the swing arm making contact the trigger pin & trigger.
2. Hold the MSV against the plate and align it so that there is no space between the swing arm-pin-trigger.
3. Adjust the MSV positioning while drying firing to ensure that it cycles freely. You may need to adjust the trigger stop setscrew behind the trigger.
4. When the Trigger held back the MSV may vent. This is normal. Though on one build my MSV doesnt vent <?>
5. Mark the MSV mounting holes on the plate and drill with a 5/32 (No. 19).
Mount the MSV2
1. Depressurize and remove the LPR Input line.
2. Mount the MSV with two 6-32 screws and fibre lock nuts.
3. Install the grip frame on to the main body.
4. Run a Tee fitting off the 3-way. The back line goes to the MSV2 "IN" port & the front goes to Guns LPR.
I ran the back line through the front block. You can do this by drilling and tapping two 6-40 barbs on either side of the front block
Pressurize the gun and Time it <-- Fun part!
