One more thing to watch for is 250 psi water hoses . What good is 250 psi water hose when most of these gas powered pumps only have psi ratings of 45 psi. You have to spend about 1400.00 to get pumps that have psi of 150psi to 200 psi.Sounds good, but just another marketing sales ploy. If you really want somthing that counts, get larger water course swivel and larger drill pipe, these are what make a differance in well drilling.
Life time warranty Drill bits. When you can build these bits for 3$ bucks a bit no problem replacing them free. Most are just flat bar welded to a .50 cent pipe nipple. Real drill bits cost! But real drill bits drill wells.The small toy bits do work, but only in perfect condtions, when is the last time you had a perfect day.
3.5hp or 6.5 hp or 13 hp......
when buying a small portable rig or if you build your own rig using our rig plans book, hp is not very important. With a gear reduction gear box the hp does not make very much differance. Most people worry about what hp to buy and don't even worry about drill pipe size or water swivel water course. size Water course and larger drill pipe is what make drilling better and easier.I have even tested one rig with small 2hp power head. The 2 hp power head works to 100ft deep with no problems.It is nice to have alittle extra power when you need it, but don't base all your energy trying to get more hp.
Who makes the best portable rig? Post hole digger conversion rigs are almost al the same, The only thing differant about differant brands of portable rigs is the swivels & frame designed. A Lot of special POWER words discribe the frames . THE FRAME ONLY DOES ONE THING, lift powerhead and drill pipe up and down. If it goes up and down there in nothing else it needs to do. It's like a remote control tooth pick, some things need to stay simple and don't need improvment.Thats why i suggest you build you own rig. Light weight steel and no extra braces works great when shipping rates depend on how much it weighs. DO YOU WANT A HEAVY DUTY RIG THAT DRILLS, or do you want a rig you saved 150.00 on shipping cost . Once you start drilling it comes apart like a 2.00 Suit case.
Water Swivel PSI Ratings .
You must find out what the swivel weight rating is on the rig your buying. The Swivel weight rating will let you know how deep it will drill. If your swivel rating is only 200lbs, then that means you can only put 100lbs of drill pipe weight on it, so your limited to only drill what ever depth 200lbs of drill pipe goes. The only reason companies do not post there swivel weight ratings is, then you would figure out that it is not possible to drill as deep as they advertize, because drilling depth and weight ratings do not match up.. If your drill pipe is 50lbs per 10ft joint, then to drill 500ft your total drill string weight would be 500lbs per 100ft . So 500ft would be 2500lbs, plus bit weight and then add alittle more for drill mud and bore hole drag.
Please stay tuned, i will be adding and updating this later.
