I'm looking for one

[@AJTarnas]

can you post details of how you made your bailers? i'm trying to make a dart bailer and can't find any decent schematics. the flat/flap valve bailers i've made aren't working. don't seem to collect any sediment.

[@haynillesen]

what material are you bailing?

[@AJTarnas]

@@haynillesen drilling mud and cuttings. mostly sand, gravel, and clay/adobe.

[@haynillesen]

@@AJTarnas Are you using any casing?

[@AJTarnas]

@@haynillesen not deep enough to do so yet. if the bailer could pull out even 0.1 liter of cuttings per drop, i'd be ok with that (1L per drop would be ideal). then i would use a casing and be pulling material from under the bottom of it.

[@haynillesen]

@@AJTarnas I guess you are from Amerika , there is a site : The Driller , already been there?

Hi there. I wonder if you have come across this simplistic design of a cable tool rig used in latin america and if so, what made you go with your design? kzbin.info/www/bejne/gnnad6mvp69li9E I'm thinking about building something but the wheel thingy looks far easier to me than a full cable tool rig

[@cabletoolafrique]

The full cable tool rig allows the cable to stretch and snap back after the bit impacts, which conserves energy and keeps the cable under some tension so it will drill a straight hole. The bit is also less likely to stick in the mud and you can feed it down in a controlled manner at the rate it will drill. The freefalling clutch in the simple machines such as you linked to is fine in soft ground if you don't have very heavy tools, but I would not use it in rock. Your arm will fall off with fatigue before the well is complete from pulling and releasing the lever.

@@cabletoolafrique Thanks, your points are understandable. I'm still trying to figure out, whether my soil is more soft or hard..
