Very interesting.  It's really helpful to be able to visualize the dredging process.  I'm still not seeing anything that leads me to believe the money arrived by any other means than dredging.

After seeing that I'm more skeptical. That cutter head is a serious meat grinder. Spacing, rpms, etc we need to know to estimate the chances ...

I would imagine there is quite a bit of suction pulling material through the cutter head.  Wet money bundles have some flexibility to them, and the bank bag would be pretty slippery after spending some time in the drink (slimy coating of algae).  Remember, this is a dredge with a high volume pump, not a food processer

WHICH CUTTER HEAD IS SUITABLE FOR WHICH TYPE
OF SOIL?
Different cutter heads are designed for different types of soil,
for instance, hard soil, non-cohesive or cohesive soils have
different requirements:
• For hard soil, a cutter head should be used that can
withstand impact forces on its teeth. It should be heavy but
have a small contour with replaceable teeth so that it can
withstand extreme wear on both the cutter head itself and on
the teeth. Often more teeth (or chisels) are used for hard soil
and good, accurate tooth positions are necessary.
• For non-cohesive soil it should be possible to achieve high
production rates. A good mixture formation with replaceable
chisels or cutting edges will be able to withstand wear. Here
as well, good, accurate tooth positions are needed.
• And, for cohesive soil, a primary concern is that the cutter
head does not become blocked. For this reason, the cutter
head should be round in contour and large enough. It may
require fewer blades with different types of edges (e.g., plain,
adapter, toothed or serrated) on multiple smaller teeth.

It is usual to make the opening into the suction pipe to the pump slightly smaller than the passage through the pump. in this way any solid objects that once entered will go through without choking. the size and character of some of the solid objects that will go through a dredging pump are surprising. stones and boulders of great size and weight are frequently passed. and in one instance a 4 foot crowbar went through the pump. six inch cannonballs have passed through the pump.

I guess passing Kidney stones wouldn't be an issue either for the dredge  :

Nice post Georger, but it appears you throw another wrench into our fun 

Hopefully we can get the right bands. is there nothing simple about this case?

Well Kaye says his minimal stretch in his photos was 150%. So that would roughly make the bands 3mm x 38.3mm or  0.118" x 1.508" ?  That cant be right! Something is wrong.

Dimensions on a $20 dollar bill are:  2.61" x 6.14"  or   6.6cm  x  15.6cm.
 
Maybe just email Kaye and ask him what the dimensions on the bands were, and any other specs he has ?

Is Tom using the SeaFirst type bands in his stretch photos?  All he says is: 'He Long further stated that the differences in chemical composition of their rubber bands produced 1971, to the bands they supplied for testing, would be minimal. Mr. Long provided a significant number of the proper rubber bands for use in testing for which we are grateful.'   Not one word from Kaye about specs on the bands he worked with in his tests?

Tom emailed offering to send me some rubber bands! I sent him my address as soon as I seen his email.....

Yesterday, while working and filing in the back room of my office, I stumbled across a file box I packed in packed in 2005. I found rubber bands around some of the old files. Some were starting to deteriorate and others were still holding up like the day I put them there. The storage area is dimly lit and climate controlled at 70 degrees. The bands were in a cardboard bankers box with a cardboard top.
