- High Volume/Harder to transport 25l Dual Tank High flow ~145psi (Full Baor used in testing)
- Hot Glue Gun
- Hot Glue
- Saw
- Hammer Drill
- 10mm Drill Bit
- 1mm Drill or Smallest drill bit possible
- Impact Drill
- Socket Set & Ratchet Wrench
- 12mm Socket (Or Whatever Clears the 1/4' Coupler)
- Impact Drill Socket adapters
- Teflon Tape.
- Recommend getting an overall air compressor kit
- Hearing Protection
- Air Compressor is 96db
#### Build Instructions
##### Short Explosive Machine
1. Take the PVC Pipe End Cap & use an 8mm drill to make a hole approximately in the centre. This is a pilot hole for the next step.
2. Use a Socket that clears the 1/4' Coupler. With a an impact drill, drill into the PVC end cap with the coupler until it's almost flush.
3. Use a ratchet wrench to tighten the whole way.
4. Use Hot glue to seal both sides of the coupler.
5. Teflon tape exposed connecting points; Coupler & NITTO quick release.
6. Attach Ball valve to coupler with the handle point away from the baffle.
7. Attach NITTO quick release to the ball valve.
##### Rifle Machine
1. Basically the same as the Short Explosive machine but with the smaller diameter PVC pipe.
##### Artery Long Machine
1. Cut Vinyl Tube to 2.5-5m
- Blood volume dependant, 2.5m for 200ml
- Recommended to pre-make multiple lengths if required.
2. Create a Hot stopper at the end of the Vinyl Tube.
3. Wait 5 minutes for the hot glue to set and harden
4. Using a small ~1mm drill bit, drill through the Hot gun plug.
5. Place hose fitting on vinyl tube ready to be attached to the rest of the machine.
6. Attach Barb & Quick release fitting to the handle release
7. Attach Vinyl tube to the barb & tighten hose clamp
8. Attach air hose to quick release fitting
#### Operational Instructions
##### Explosive Machine
- 90 psi firing range
- Lower can be used depending on shot size & area
- Recommend going as low as 30-40psi for extreme close up
- Trial for desire effect/impact
- 100-200ml of blood.
- Point at Subject & release valve when pressure is in the correct range
##### Rifle Machine
- Basically the same instruction as the Explosive machine
- Use as much Blood as needed
##### Artery Machine
- 60 psi firing range
- Using skin safe or regular tape attach to subject
- Alternatively hold & point tube at subject or target
- Load 100-200ml from the Hose clamp side (Rear)
- Press Down release vale to fire when in the desired pressure range
#### Operating Notes
- Increase either PSI or amount of water to desired effect, these are the two primary variables. (PSI & Blood Viscosity)
- Total volume of blood is a secondary variable. (Blood Ml)
- Higher water to syrup content makes for more mist
- Prefire with water to have a cleaner test method.
- Not recommended to record sound due to Compressor noise. (96db)
- Syrup Base for blood will impact overall performance refer to point 1 & Consider the following:
- Golden Syrup
- Glucose Syrup
- Melt/Boiled Sugar
- Each of the above will have different properties & viscosity
- Recommended to preform test fires if possible
- When making the blood for machine use it's better to over compensate with colouring due to the air pressure making everything less thick
- Bias Red Colouring, more colouring will make the blood appear darker.
- More Golden Syrup will increase thickness without impacting the colour that much, use as much as desired.
- Adding green dish soap to the mix doesn't impact colour that much but will make cleaning easier.
- Rifle config can use the thickest blood
##### Recommended shooting/rolling order
1. Pre Checks
- Framing
- Blocking
- Safety
- Conventional Production elements
2. Start Compressor Charge to desired PSI.
3. Start Loading Blood & Rolling Camera
- Turn Over
- Slate Camera if needed
4. Confirm when Ready to Fire & Action
5. Release Valve within ~15 sec of reaching Desired PSI
