Crevicing

[Tathradj]

I am going to do this with a PVC Yabby pump.
Can glue a threaded section on the end so you can
access the washer area for tightening or replacement.
If you really want one of these to draw, Use a piece of
thong.

Tathradj you are on the money i was wondering what to use for a washer :Y:

Yeah, a pair of size 12 thongs from BigW $1.50!
Get a few gaskets out of a pair!

Cheers! I do have a personal preference of black poly over white pvc.

Here's a thought - and I know there is no such thing as an original thought - but how easy do you think it might be to rig up an old washing machine water pump and hand operate it using a crank handle; maybe a pully system to get the speed right and then set up the pipes to work as a hand operated mini dredge?

Then could also set up an old bicycle to peddle it - may be able to operate for a longer period.

Clearly though would require one person to crank the pump and another to probe the crevice.

Presumably this would pass the regulations and may be a little easier to work if any volume is required - or maybe just scale the whole thing down for even the small crevices.

What do you think?

My friend suggested something similar 19.3. A plastic 44 gallon drum with a hand pump attached to it. I said it might be a tad awkward to get it down to the river if it's a fair walking distance, but if you can park close by, it would probably not breach the regs if it's hand pumped.

Tathradj?

I have an old yabbie pump somewhere...will have to dig it out and modify it.

Loose the old gaskit for a thong gaskit. I get a nice finish on the circumference using a belt linisher. Belt sander will do the same.
