Re: Made a 145cm inverter, 10mm shaft

Hi Memosub, I made my back rollers 27mm, measured in the center of the roller. I router groves in gun body so the bands are partly in the grove to stop the bands shuddering when tracking.

Re: Made a 145cm inverter, 10mm shaft

You mean Dean's Koutras from Addiction shafts?
Addiction Shafts do look very well made. I definitely buy some to try when ever I get back to work.

Re: Made a 145cm inverter, 10mm shaft

Hi Neven, I didn't think about the flopper pin holes, you might be correct.
I will have to have a look at the 8.5mm shaft I made. I believe the shaft is twisting in flight and coursing the...

Re: Made a 145cm inverter, 10mm shaft

Hi Neven, Your gun looks extremely powerful. I know how hard that EPS construction foam is. What bands and percentage are you using on your gun.

I was target testing one of my smaller 125 band...

Re: Made a 145cm inverter, 10mm shaft

I see Neven (Gladiator) & Alemania don't use a track in their guns. It would be interesting to know the reason why they don't.

Hi Pete, Your findings of recoil is very interesting. You have highlighted these very well with your screen shots.

Re: Made a 145cm inverter, 10mm shaft

Hi Pete, You can see the 10mm shaft flexing as it leaves the gun. But the shaft flight is quite flat.

Re: Made a 145cm inverter, 10mm shaft

I believe you are correct Pete, I make my front roller slots as far forward on the gun as possible, so the shaft has left the gun before the recoil lifts the front of the gun.

Re: Made a 145cm inverter, 10mm shaft

Hi Pete, I did think this, I welded a fin on a hunt shaft on the milled flat that goes into the trigger. Still have shaft lift. But I don't think there is a problem with the shaft lifting, As I still...

Re: Made a 145cm inverter, 10mm shaft

Hi Pete,
I have been using inverter & roller spearguns for many years now. I can't think of any problems I have had, other than the wishbone slipping. I now do a double sheet bend to stop the...

Re: Made a 145cm inverter, 10mm shaft

Hi Jon, I find I'm more accurate shooting a inverter gun with one hand, not sure why this is. This inverter does have a little recoil. I don't use a kicker band. The testing I have done, I get more...

Re: Made a 145cm inverter, 10mm shaft

Thanks Neven,
No I haven't tried smaller O/D bands with a higher stretch factor. Could be a interesting test.
