Where is a good place to get more couplers and drill stem? I found out this weekend that there is a chance I could hit water at 20'. My parents house which is a little higher than our camp had a hand dug well when they moved there. Also there well is 140' but they hit water before that.

Down pressure may just be the weight of the drill stem. Note the motor size and how much rotation force it may be able to supply. In softer ground it may be possible to stick the bit if it goes down too fast. On hard rock the bits may not stand up to excessive down pressure.
Please note that I've never been around this type of drill but have seen this type.

Egon is correct. These units don't have the power to utilize down pressure. The weight of the drill stem adds up though. I found myself with the hand on the winch handle most of the time. If a rock gets involved, you have to let it chip away at. Otherwise everything starts taking a beating.
One benefit of this much slower drilling process is it is easy to keep up with shoveling out the cuttings. I was watching a crew with a crappy but real drill rig and the one guy shoveling was getting a workout. He had to help with the stem changes so he did not get to rest then either.
I am dot trying to discourage you at all. There is a certain amount of pride that fuels me when you can get something free. One of the reasons I enjoy sailing.

One could use a screen system to eliminate the shovelling. It may also help to use a piece of say six feet by eight inch casing to start the well in. This could even be increase to about twenty feet to give protection from surface water. The out flow in the mud pit (rat hole ) will seep down and the clays will sorta seal it off. This pipe also works well to hold the pipe vise when adding/subtracting drill stem. Vise is a whole lot better than a pipe wrench that gets knocked off and gives some fishing time off.

Bunch of years back 3 of us chipped in and purchased a Deep Rock setup.
As far as we were concerned it was a POS powered by a lawn mower engine.
Other than supplying the engine they had a cuppler to inject water
Bits were nothing but exhaust pipe with a hand full of carbide chips brazed onto the end as well as some slits for cutting sand I guess.
Instructions were to braze more carbon chips when worn off (which was like 5 mins and maybe 1 inch of drilling.)
Any loose gravel in the bore hole really did a number on the bit as they simply tumbled and mashed the bit to death.
Probably a great rig in sand and maybe clay but not in any kind of rocky soil.
At that time phone support was vague and evasive usually suggesting another add on option that they offered.
All in all we achieved about maybe 5" of drilling and retired that rig. Later on one of the guys used the engine to repower his lawnmower.
In those days they advertised in the back pages of Popular Mechanics and Mechanics Illustrated.
Really surprised that they are still around.
When phoned for advice they claimed that in granite such as we had it was a great performer just a but slower and would make a nice clean bore hole.
My 2 cents!

I think everyone should try to drill a well if they want. No matter if it works or not, it will give you a new respect for well drillers.
