HW 90 Pump & Adapter !

Hi Gedfinn,

11.8 is too close! (insert gay smiley thing with tongue out)

I have to agree that the HW pump is a Heath Robinson affair. I have found that you need to give it about ten good pumps to charge the pump and line before it starts to fill the cylinder. Without a gauge it is hit or miss to know the right amount (see one of my first posts about letting fly with a super sonic .17 pellet in the back garden!) I also found that tapping the release valve can dump the whole lot in one go too!

Certainly the stirrup pump is the way forward and I'm suprised no-one has made an adaptor for the HW90 et al before. I'm sure you'll have a few interested parties for it. Good work fella.

Cheers Boondock

It looks to be a good idea.

My neigbour is a mountain bike fanatic, and he has a stirrup pump for doing his bike tyres.

Its a good quality affair, and I borrow it to do my car and motorcycle tyres, and its very very easy.

As the guage on it has a more suitable range (up to about 50psi I think), maybe it would be ideal for this application...???


opps just realise i read BAR for PSI....scrap the above!!!!!!!

I have been using a similar setup with my Logan stirrup pump for a few years now. Once a year I strip, clean, check/replace the O rings and tophat, relube and then pump it up to give me +- 11.4fpe with webley mozzies. I agree 11.8 is a little high if your using a heavy pellet as with a lighter pellet you'll be over the top. Better be SAFE than sorry
Cheers and safe shooting
