(there was a url link here which no longer exists) - 4x5 development tubes

For those who have never tried tube development, this is a short read on how to make them. Cost is about $5.00 per tube, once a 10' length of drain line is bought. Time is about 5 minutes each, once tubes are cut to length.

Materials: 1 - 6" length of 1 1/2" ABS drain line from plumbing supply or Home Delay
1 - 1 1/2" cap (flat bottom is easier to use than round type as tube stands up)
1 - 1 1/2" female threaded adapter
1 - 1 1/2" screw plug
1 - 4" x 6" fiberglass screen
1 - Small...

Question, I have heard of PVC tube, What is ABS ? Is it always black ? What is the 'Wall' thickness ? Cheers Barrie B. Australia.

Barrie, ABS is the generic name in the U.S. for drain lines used in residential & commercial plumbing. It is always black. The I.D. of this tube is about 120mm and wall thickness is about 2.5 or 3mm.
Three things you must know for plumbing:
1 - Payday is on friday
2 - $hit flows downhill
3 - Don't lick your fingers

Thanks, Drain pipe in Australia is 'White' and is semi-transparent. I shall have to look out for that ' Black' ABS material and see where it is used. ( Irrigation pipes used in agriculture is black ) Cheers .

ABS is the name of the polymer [Acrylonitrile Butadiene Styrene]
ABS is harder, more resiatnt to breakage, and has a nice shine to it.

Does it make sense that this same setup would work just as well for 2x3 sheet film?
Seems as tho the only adjustment would be cutting the screen to fit 2x3 ... and I guess the pipe wouldn't need to be as long.

2x3 or whatever size you need. Just make sure the tubes don't pass light. tim

Make sure the screen is slightly larger than the film size. If not, the screen can pull out and leave the film behind with scratches on the backing side.
Chemicals done in the dark.

ABS is not the easiest to find in some areas of the country. An option is to buy some Krylon "Fusion" spray paint and paint them black. It is made for plastic and works really well. If your doing more than one tube at a time, try getting a tub with a lid and large enough to hold 4-5 tubes and put in enough stop bath to cover all of your tubes. Then when developer is done, simply empty the used dev. and plunge the tube into the tub of stop bath and it can stay till the others go in. This also can be done under a safelight or DIM room light if you get it in the tub in a few seconds. Don't dilly dally here. Then unload and into a tray of fixer (safelight is okay at this point) and voila. The tub is then covered till the next dev. session and no fumes and stop bath is cheap enough to mix in large quantities. My tub was bought at Wal Fart for about 6 bucks. It is around 20" long 8" wide and 8" high or deep.

I don't bother with the screen. The outside of the curved film is the anti-halation coating, and that clears in the wash if not before. I also put a light trap / inversion top on mine. Dead Link Removed .

I have heard that black ABS is UV-opaque, but white PVC is not.
ABS is not (apparently) easily found in my state (Michigan) because plumbing code doesn't require it...therefore suppliers do not stock it.
I've debated a drive to a neighboring state, but it' s not worth the 3 hour drive.
Maybe someone for whom it's a garden-variety item should sell kits and retire from their day job~!

Tim,
can you tell me what the fibreglass screen material is like? (we don't have screen doors in the UK). What size is the mesh, approximaltely what size are the filaments? Is there any benefit in using fibreglass?

I bought the stuff today and made a couple, but it cost more than $6.00! Fortunately ABS seems to be ubiquitous in the hardware stores here in B.C. Should be worth it. Very easy to make. The only potential problem I see is the fibreglass screen. It wants to unravel, and I don't see it lasting very long.
Re the fibreglass, go to a boat supply place for it. They use it for fixing and making fibreglass boats, amongst other things. It's not used for screen doors. It's more like cloth than screen.
