  1. Great writeup! But, I've got a new wrinkle on a gold pan....my automatic panning machine AKA "Sweep Jig". Utilizes a flexible bottom, or diaphragm. I've been working on this since August of '16. Patent has been applied for. You can see the old prototype running here:Sweep Jig at Bonanza Bar Works well, even without water. Jim

    TDI SL Battery Pack Up Grade

    I've been using the Reidman pack for a couple of years, with no problems. There was a recent post on another forum saying that resistor #9 got too hot to touch when he used the 4-cell pack. I haven't checked mine, but am going to keep using the 4-cell. It may be that Whites don't want to produce a pack capable of 16.8 volts when the capacitors in the power supply are only rated for 16.0v. Using the 4-cell pack is counting on the safety factor built into the capacitor rating. I'm using a charger that lets me set the max voltage, and I'm now keeping very close to 16.0v, just in case. Staying at 16v also increases the life of the pack. Jim

    What Are They?

    Man, I really like that green in the second pic, Jim...gorgeous. And I agree....DD does know his rocks! Jim
  4. I understand. I have no idea what changes he's made. I thought I bought one of his early units. I've had it 2 or 3 years. I use an adjustable-voltage charger on mine. I can set the final voltage to any level I choose. That saves pack life by limiting the voltage to 4.0V/cell. I can also use that charger on my RNB pack for the GMT, and DFX, at 12v. My adjustable-voltage charger has a wide input range, too...from 8.0 to 65v DC. Jim

    Yup, Fred....I can't count the nights I've spent sleeping in the cab of a pickup when the weather turned south...even in the winter up here. ya do what ya gotta. Jim
  6. Not so, Luke. Here's a pic of my Reidman pack. No point on the bottom is higher than the perimeter edge, as seen. Jim

    I think it's mainly the cost of compliance tests for the EPA. Takes a lot of vehicle sales to get that cost back. Jim
  8. Reidman removed the factory base in his pack, and replaced it with a thinner sheet. it slides in smoothly, with no untoward pressure. Jim

    Will do. I've got the auto in the Dodge, and have had great luck with it, but know nothing about the Cherokee automatics. For a really serious backroads rig a stick is the way to go. Jim

    I like the sound of that. I've considered doing the same, for shorter trips. Just me an dog, don't need a passenger seat taking up room. I was thinking Cherokee, too. Jim
  11. Jamie, I don't have a clue. Jim

    Yup...I've read a lot of good reports on the Trooper. Solid outfit. Jim

    All-around Vehicle For On/off Road

    I've been driving the same 2001 Dodge diesel 3/4 ton 4x4 since it was new. This the 18th year. it now has about 307,000 miles on it, and well over 20,000 of those on dirt. It's never stranded me. I put $10,000 into it a year ago, and brought everything up to snuff. Now runs like new again. Even with that investment, the cost of ownership is under $3,000/year, with many years of use ahead. I put an aluminum flatbed on it when new, and it has hauled more equipment and supplies than can be believed. Or, pulled my little Alaskan camp trailer, with the 4 wheeler on the flatbed. I've logged every gallon of fuel put in it, and for all uses has averaged almost 17mpg. It would be the last of my possessions sold. Here's a pic of me stuck in the Wyoming clay a couple of springs ago. Had to wait 3 hours for it to dry out before continuing on.
  14. That pack is cheaper now than when I bought it. I'm pretty sure I paid $150.00 for mine. Jim
  15. This is the pack I'm using. Direct plug-in replacement, but 14.8v nominal rather than 11.1v of the other lithium ion offered. Actual max voltages are 16.8, and 12.6. Nominal voltage on li-ion is 3.7v/cell. Max is 4.2v/cell https://www.ebay.com/itm/Whites-TDI-SL-custom-Li-ion-14-8v-Battery-Higher-voltage-to-push-SL-to-new-depth/222810586564?hash=item33e08bbdc4:g:HfMAAOSws5Baah8g
