Thanks RM 
That first link is a good one
I did a forum search and missed that one 
Have to go to Bunnings later this afternoon so I might try to make one.

I thought I would follow the directions in the first link and try to make the pump.
So off to Bunning this afternoon to return some left over kitchen tiles from the reno and get store credit.
That sorted , I had $121 credit to play with bought a few items we need for the reno, which left me with $71 for the pump parts.
I thought I would also get a Tradeflame TF/ULTRA blowtorch ($46 )and trade flame yellow gas bottle($15 ) but bugger me they had the gas bottles but didn't have the blow torch on the shelf and when I asked them to check the stock list on the PC , it showed they should have 10 available in store ???
Strange but any way back on the bucket list for later and off I went to the plumbing section to start picking out the items listed in the pump instructions, before the store closed.
1- 50mm – 20 mm reducer HP (High Pressure) couldn’t find this part.
2- 50mm coupler HP. Couldnt find this part..
3- 50 mm x 88 Connecter DWR (grey sewer pipe).. available.
4- 1m x 50mm Pipe ..available..
5- 25 mm T piece... available
6- 25 mm threaded cap and threaded connector DWR - couldn’t find.
7- 50 mm threaded cap and threaded connector DWR - couldn’t find.
8- 15 mm – 20mm connector (NOPE ) and 15 mm x 1m length of PVC ..yep ..
Buggar decided not to buy any parts until I can go home and go to my local store and buy everything at the one time.
Disapointing but 
happens

Hit our local bunnings on the way home and bought a matgas bottle, tradeflame blowtorch and the parts for the crevice pump.
Took me about 20 minutes to put it together (not glued) and give it a test.
Works ok but the old rubber thong I cut out for the plunger is not as good as I hoped.
Will have to look at tweeking the plunger before glueing every thing together .
Here it is ..

Wouldn't a yabby pump do the same thing?

I recon it would goody but not only would it cost a lot more $70 yabby pump compared to parts from bunnings for under $25 but the most important part is, I wouldn't have had the fun of making it myself

That is true nucopia ..
I swapped some fishing lures for a yabby pump...
Plus bought a crevices tool to fit on the end of it...
But would like to set it up so I can pump in to a bucket...

You hit on a bargain Goody
Maybe try attaching a T section with an end cap between the pump and the crevice tool attachment , like this

I’m scratching my head.
I cut an old thong to use as the plunger aeal, worked for a bit then shate itself.
Does any one have a good idea for what I can use instead.
I tried a thing peice of thong rubber between 2 plastic washers but that was over kill .
Created so much suction, it wouldnt allow me to pull the plunger out

Try steel washers with 2-3 thong washers in between. I used some shocker washers, big area and small hole. You have to wear it in a bit. I have valves on mine so I can pump into the sluice.
Used the outlet of a sink, cut it down and used some 1mm rubber for the flange. Bolt in the middle; simple valve screw into 50mm pipe .
Home made sluices x 2 & highbanker, ATX, Garret Supa Sluice, Quanta pan, 2008 - minelab 4500, SPO1, Makro Gold Kruzer

How about drilling a few small holes in the outer sleeve at the top.
That will relieve the internal pressures above the thong washer.
I've seen that done.

I think a might have it sorted BW
Changed the thong rubber today for some foam rubber from bunnings, which I can compress between two washes, using a bolt and wing nut.
Looks like it might do the trick. Tested at home and gets good suction the litmus test will be how it goes in the crevecis and cracks out bush..
fingers crossed

The size of the washer to the diameter of the pipe dose play a roll in the seal. And yes a 10mm hole at the top is needed to vent back pressure.
