exentrik Posted February 13, 2006 Report Share Posted February 13, 2006 Thats cool. I really want one. I kinda wanted one before, now I really want one Link to post Share on other sites
crackisbad Posted February 13, 2006 Report Share Posted February 13, 2006 1 question: do you guys think the cylinder can provide enough air for this barrel?? <{POST_SNAPBACK}> So as to avoid "barrel suck?" Â I have a quick trick (ok maybe not so quick as it requires taking everything apart) i learned about how to test if your cylinder has enough volume for the barrel: Â Fill the barrel (only the barrel) with water (cover one end with your finger, duh ) till its full, then cover the nozzle on the cylinder head and pour the water from the barrel into the cylinder and see how much of it fills up. If the cylinder gets filled up/overflows and there is still water left in the barrel, then the volume of the cylinder is too small. If it ends up even or the cylinder doesnt get completely full, then you're good. Â If it is too small i think you're SOL because i dont know where you'd be able to find a bigger small cylinder for that. But if i had to guess; since it is a TM i would assume that they would have thought about that (hopefully) and made the cylinder big enough. Â If you do this let us know how they measure up... Â P.S. I dont remember who i learned this from, so i cant give proper credit.... Link to post Share on other sites
InitialD Posted February 13, 2006 Report Share Posted February 13, 2006 Uhm.. that's cool.. that way we can measure the effective barrel length. Link to post Share on other sites
gunner-airsoft Posted February 13, 2006 Author Report Share Posted February 13, 2006 as I promised I will take some new photos for the internals, here we go:  2 screws here  the barrel, same outer dia as normal aeg, 8.5mm  hop up bucking  hop up chamber, there is no small rubber thingy to press the hop up bucking.  cylinder set  cylinder head without the nozzel Link to post Share on other sites
gunner-airsoft Posted February 13, 2006 Author Report Share Posted February 13, 2006 the nozzel  spur gear A  sector gear  rear side of sector gear  tappet plate and its spring  spur gear B  below is the mp7 motor, with its big bro on top  bevel gear and the anti reverse lacth  gear box , and the cut off lever attached  gear box Link to post Share on other sites
gunner-airsoft Posted February 13, 2006 Author Report Share Posted February 13, 2006 tried to fit in a 6mm bearing  but the axis doesnt fit  the axis if the mp7 gears is nearly 2.5mm, normal aegs gear is 3mm axis Link to post Share on other sites
wildstallion Posted February 13, 2006 Report Share Posted February 13, 2006 Maybe you can find a 0.5mm thick sleeve to go over the shaft. I would try a model shop first they sell all sorts of pipes and watsits Link to post Share on other sites
gunner-airsoft Posted February 13, 2006 Author Report Share Posted February 13, 2006 I think I will find some industrial supply shop for some bearings which will fit.....   Maybe you can find a 0.5mm thick sleeve to go over the shaft. I would try a model shop first they sell all sorts of pipes and watsits <{POST_SNAPBACK}> Link to post Share on other sites
wildstallion Posted February 13, 2006 Report Share Posted February 13, 2006 Or better still source a bearing which is internally 2.5mm I suppose. There are plenty of bearing specialists out there. Link to post Share on other sites
DarkAngel1 Posted February 13, 2006 Report Share Posted February 13, 2006 heaven forbid we should just leave them standard for a few months until the nicely machined upgrade parts come out. Â thanks for the guide btw, see your rep stats for MY +1. Link to post Share on other sites
davedawg123 Posted February 13, 2006 Report Share Posted February 13, 2006 That motor shaft looks awfully small. I hope it holds up to abuse. Â Great job on this little guide. Thanks! Link to post Share on other sites
skandarn Posted February 13, 2006 Report Share Posted February 13, 2006 why not just buy this? http://www.wgcshop.com/pcart/shopper.php?i...CFBAH_srch_g18c  maybe even g18c cylinder works Link to post Share on other sites
skandarn Posted February 13, 2006 Report Share Posted February 13, 2006 DP Â here is a link for the cylinder while im at it http://www.wgcshop.com/pcart/shopper.php?i...18CFC_srch_g18c Link to post Share on other sites

gunner-airsoft Posted February 14, 2006 Author Report Share Posted February 14, 2006 some of my customers tell me just cut out the wires from the original charger and clip the connector to a normal charger will work. Â I didnt tried it yet, but there is just 2 wires coming out from the marui charger, so it make sense.

staticzero Posted February 14, 2006 Report Share Posted February 14, 2006 Have you tested the cylinder compression at all? It would be interesting if there was some 'free' FPS to be had there by improving it. Link to post Share on other sites
gunner-airsoft Posted February 14, 2006 Author Report Share Posted February 14, 2006 the 18c cylinder seems too short for MP7..... the bearings may work~ Â DPÂ here is a link for the cylinder while im at it http://www.wgcshop.com/pcart/shopper.php?i...18CFC_srch_g18c <{POST_SNAPBACK}> Â Â staticzero, Â cylinder compression? do you mean sealing the nozzel by finger and press the piston forward?? Â if yes, I tried already, it is totally air tight. and the piston head is also have its holes drilled by marui, so we dont need to do it ourself. Â I will try to charge the battery and shoot it tonight, hopefully I can take a video and put it here. Â Thanks all for the rep points!! Link to post Share on other sites
staticzero Posted February 14, 2006 Report Share Posted February 14, 2006 Yes that's what I meant. I'm actually saddened to hear it's good (though I'm not surprised). I was hoping that it might account for the lower than expected FPS in some small way. Link to post Share on other sites
Ryan220 Posted February 14, 2006 Report Share Posted February 14, 2006 Gunner, when you test fire yours today/ tonight could you chrono it please? It would be nice to compare it againsts Far Easts results. I ask as Im supposed to be picking mine up today or tomorrow and it is of particular interest to me. Â If no-one (Gunner in particular) minds, as soon as I get mine I'll chrono it and put the results up on here for everyone to share so we have a wide range of results to consider.

staticzero Posted February 14, 2006 Report Share Posted February 14, 2006 FWIW I chrono'd the three I had in my possesion and the results agreed with FarEast's findings overall. Link to post Share on other sites
Tommygunn Posted February 15, 2006 Report Share Posted February 15, 2006 Instead of using water to measure volume why don't you just use 'pie r squared x height' to obtain volume and compare the two results? Saves on total disassembly and preparation/drying time. Link to post Share on other sites
