AGO works with a Paterson funnel that has three holes in it, and every AGO comes with one. To get more Paterson Super System 4 tanks ready for AGO, drill their funnels with our template. The funnel stays light-tight with the holes.
Print the template
Download the funnel drilling template and print it at 100% (Actual size). Measure the two lines beside the label. They must read 115 mm and 31 mm. If they don't, fix the print setting and print again.
Cut it out
Cut along the grey line.
Tape it to the funnel
Take the funnel out of the tank. Place the template as the drawing on the label shows, with the edge marked FRONT EDGE OF THE FUNNEL along the front edge of the funnel. Tape it down firmly so it can't move while you drill.
Drill the three holes
Drill a hole at each cross with a 13 mm (1/2 in) bit.
Clean up
Take off the paper, trim loose plastic from the hole edges and rinse the funnel so no shavings end up on your film.
Holes face down
When you attach AGO to the tank, turn the funnel so the holes face down, towards the bottom of AGO. See Assembling.
Prefer not to drill? The Modified Funnel and Rear Stand Kit comes with a drilled funnel, a rear stand and three adapters for older Paterson tanks.
