Quote from Chuckd

I don't know how you CA guys ever handled it over there.

Easy for me....I don't go there to play.;)

Cheers. Don

Thanks Chuck, that's a lot of ET. I would leave the band length as you have them, you will develop the strength to cock the last anchor before you know it. Nice gun.

Cheers, Don

Cool gun mate, but what does the ET do on a single band gun? I don't believe the shaft is whipping with the long, smooth duration of thrust. I know the bubble freeshaft guys don't want their shaft dropping out while a AJ trys to kiss them on the reg, but I believe your a freediver.

Cheers, Don

Quote from metelin

can't say that i disagree with any of the above views but the reality is we live in a place (ca) and at a time where the environmental point of view rules. i think the photo is regrettable, as i think photos of lots of dead fish, lobsters, etc no mater if they're legal or not.

now, we are faced with the possibility of someone completely opposite of the current president being in charge of the ca dfg, nice. keep pics posts to a minimum, show only your closets friends and people you trust, otherwise we are going to pay the price no mater where the pics come from.

just my 2c.

Very well spoken brother. Even before the internet when me and my friends had a ''day to remember'', we did not send all our images to our club news letter, even though all were legal catches. Our photos were handed to close friends over a beer or coffee and put back in our back pocket. '' The conversation usually went ''Come with us next week, we'll put you on some nice fish mate''.

Cheers, Don

Quote from LunkerBuster

but they are amazing.

I have had mine for over two years and they are in new condition less a few small scratches..i use the last model of the H dessault pocket and they are nice. I have monster feet so my FPchoices are limited.

Thanks for typing for me LunkerBuster;) X 2.

Cheers, Don

Gratias Jose, I have been tintering with air guns going back to 83. My boat partner was a Engineer for Scuba Pro and we did some crazy shite. Playing with this one brings back fond memories of the good times we had, and the oil and gun bits we scattered the deck with.:@ We had 2 140cm ScubaPro pneumatics that were built for the Italian World Team that were pumped to 35Bar..... I still have one.;) Some where I have a Ti barrel I had machined for it, but baseball and the GF get the attention.;)

Cheers, Don

Nice mate,

Quote from Marco

Why do you change the oil? When I used fartguns I didn't touch them unless something was wrong.

This gun is still under my development plan. It has a ported inner barrel and modified trigger assembly.
I traded out the stock piston for a later model and will be examining the OEM piston in a scope as I did all the stressed parts. I plan on pushing this kited gun to high pressures until the piston fails. Then it will see some Ti bits I'm making.

Cheers, Don

I lost track of this gun, it was out of my price range at the time, I like the box as well.

Quote from popgun pete

The lithium based grease, being creamy white, seems to be less messy on your wetsuit and clothes. The black stuff on my hand is molybdenum disulphide grease, I cannot wait to get rid of all traces of it on the guns. To take those photos I must have washed my hands four times and even then I got more of it on my hands.

Any chance of a photo of the "Cernia Velox", particularly the sliding handgrip section?

Yes, of course, I'll get it from my kids house this Sun Peter.

Cheers, Don

Say,
Initial length, L0=100mm.
Final length, Lf = 300mm.

Change in length, dL = Lf-L0 = 200 mm

So, percentage elongation = 200*100/100 = 200%.
200% means the elongation is 2 times the original length, which is 2*100 mm.

When I say I stretch my bands to 300% elongation, that is a length that is 3 times the specimen length.

Lets take a piece of 5/8 10'' long, if I stretch it to 20'' that is 100% elongation. Stretch it to 30'' that is 200% elongation. Stretch to 40'' and we have 300% elongation or specimen length X 3. This is the elongation I us for max power on premium latex.

I'm done with da math.....Fri night and heading out

Cheers, Don
