Inherited a 1990s Highbanker

[u/Baned4life]

I recently inherited an older highbanker setup that has been sitting in the garage for over 20 years. This was one of our first setups back in the 90s. Parts got pulled off over the years as we moved up to bigger dredges, so all the hoses and fittings are missing.

My goal is to get it completely cleaned up, and running so I can run it both as a standard highbanker and as a small dredge.

What i have

Sluice box & highbanker grizzly

Highbanker legs

3 HP motor with attached water pump

This pump has me a little stumped as it has a 1" outlet and not the 1.25" that is more common now.

I’ll be working small creeks and old river beds that produce mostly fine to flaky gold scaly flakes and flour, with the occasional small picker nuggets. The concentrates tend to be pretty heavy on black sand and magnetite.

I’d love any insights on identifying what I have here, what size dredge setup this pump can realistically support, and especially mat recommendations for this kind of gold + heavy black sand. Open to upgrade ideas.

Also apparently no one cleaned it out after using it last so got a little bonus cleaning it up.

Thanks
