    Quote from Dan

    I agree and IMO it's the only valid reason in this situation. Although some people will argue to the contrary and say that an enclosed track is slower to load. You should ask Jeff to open up the track a few inches near the muzzle and taper it for further ease of loading.Sorry hau there's just no other way to say it, that's ridiculous. Get rid of that POS rusting Rob Allen shaft and get yourself a stainless steel one. Really you have no choice in the matter because as far as I know RA doesn't make euro shafts with full size sharkfin tabs, which you must have if you're going to use an enclosed track.But neither you nor anyone else here freeshafts. Freeshafting is fundamentally for scuba divers.


    Regardless I'm glad you got your wish, congratz and enjoy your new toy.


    Thanks Dan---do you have 9/32 finned shafts that I can buy for this ETPGB?

    Dan--I was just saying that a heavier barrel/gun would have LESS felt recoil,LESS barrel flex and LESS muzzle flip than a much lighter barrel.

    Quote from Dan

    What is your reason then?Why does this matter if with two 9/16 bands you have no significant recoil, barrel flex, and muzzle flip?


    paste;
    I prefer a pipe gun for lots of reasons and would prefer an enclosed track pipe gun for many more reasons. But it is just my humble preference.
    For me, an enclosed track pipe gun would:
    1. Faster to reload. Many times I have to load my spear shaft fast without taking my eyes off a fish or spot below. It is easier to just start the shaft into the end of the enclosed track barrel and slide it into the mech.
    2. There is no reason that a shaft coming out of an enclosed track is LESS accurate than a shaft off of a rail and probably there is more evidence of an enclosed track shot shaft being MORE accurate.
    3. Protect my spear shaft from injury while the shaft is in the gun. Less scratches and dings to the spear shaft "enclosed" in the CF
    4. I pretty much grew up spearin with enclosed track homemade 6f wood guns in the GOM and got used to them
    5. An enclosed track pipe gun would be very fast and easy to freeshaft with
    This is just SOME of the reasons I personally prefer an "enclosed track pipe gun"

    i dont think i ever really do that anyway,, maybe under ledges and stuff.. but i think itd be an easy enough thing to remember


    sdeisen---100% agree. An ETPGB is NOT the ideal barrel for tight quarters with hard backstop like under ledges, inside wrecks, etc.


    (Sorry I'm not smart enough to put these 4 quotes together instead of 4 seperate replies)

    For this gun, yes. But I think the same track might work well for a hybrid with a little more power. This just strikes me as the kind of thing with potential beyond the oringinally conceived application.


    Tin Man----100% agreed. <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x">

    Quote from Don Paul

    What size bands and how many?
    Don


    Don Paul--Personally I am going to continue using the same (2) 9/16 bands that I currently use with my RA 120cm rail barrel for this 120cm ET barrel. IMO, it is very easy to overpower a pipe gun and adding power is NOT one of my reasons for designing this ETPGB.


    Another item to consider is that this ETPGB is going to be HEAVIER than almost any RAIL barrel.
    1. Good==because the felt recoil, barrel flex and muzzle flip will be decreased with the added barrel weight.
    2. Bad===because the ETPG MAY not float enough for some spearos in some applications. (Like me with a reel AND UW cam).

    sdeisen---IMO, I think that many here would agree that the worst case REAL LIFE senareo for an enclosed track gun is when the shaft is fired and the shaft hits something solid before the shaft TOTALLY exits the enclosed track. IMO, this is when the enclosed track is stressed the most and when most enclosed tracks tear out. What that means to me with this 120cm ETPGB is that I cannot shoot the ETPG towards any hard coral back stop LESS than 40in from the end of this gun without concern for the safety of the ET.

    Tin Man---I had planned on getting spears and bands from here; www.freedivingspearfishinggear.com .
    I know the owner of this store and we get along ok, except that he likens me to a caveman from time to time. But I don't mind. <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x">

    IMO---this ETPGB (enclosed track pipe gun barrel) is going to be a VERY GOOD product for anyone who already has a RA, Aimrite, Mako, etc.
    With this ETPGB option, a spearo can start out with a RA Vecta 90cm for his very first gun. Then later on buy a RA 120cm alum barrel to attach to his existing mech/grip and muzzle. Then later that spearo could purchase a ETPGB and attach his same mech and muzzle. SIMPLE.

  • Enclosed track speargun

    Dan---Yep. No joke. That is exactly what I wanted :thumbup:


    Tin Man---PERFECT :thumbup:
    You are the MASTER :thumbup:
    Of course the spear fits into the mech and muzzle correct? (sorry, had to ask)

  • Enclosed track speargun

    Tin Man---I guess that there is no need to type how excited I am to see this project get to this phase :hooray:
    Thanks for the info about how the CF tube looks.
    1. Do you think that the CF tube properties are correct to build ETPG barrels? I mean, is the tube stiff and tough enough for speargun barrels?
    2. Did you notice the modifications on my Tin Man muzzle? What do you think?
    3. I sent along the RA muzzle AND the muzzle line guide so that you might evaluate it for your muzzles.
    Thank you Tin Man. :hail1:


    PS---I went back to work last night for the first night back from my emergency surgery. That is why I am not on the forum as much.
    Thanks

    Don Paul---You guys gotta stop pickin on me or I'm gonna take my ETPG idea an go home <img src= " class="smiley" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x" height="23" width="23" loading="eager" data-tooltip="biggrin" aria-label="biggrin">


    spearos---How you like my new sig line?

  • UW Video questions/answers

    Dan--I don't know the answers to those questions yet and I hope that I never need to pursue those answers:)


    Video spearing education purposes---I was talking to another spearo videoer and he was telling me that he would slow down his video to evaluate how his gun/spear was working. He said that he was missing fish and that he slowed down his videos and could see that the spear was hitting the fish very high or going over the fish.
