The J-Hop Testing Thread

Necro or Necro posting is when the topic has been dead for some time, and someone posts again. Normally something that hasnt had any new comments in a good while is considered dead.. Most forums have a rule and staff will freak out in ya for reviving a dead topic. In my opinion, a topic like this shouldnt exactly fall into that category and should be ok to revive.

The necro's that bug me is when someone says "what gun should I get" and months go by and some knucklehead comes along and says what gun he suggests,lol.

Like really guy? Did ya really think the original poster was gonna wait 6 months to see what gun everyone suggests before he decides? hahaha.

I also feel gallery posts shouldnt be dead topics also..



By the way, this is just my thoughts, other Mods may feel differently

Sorry kids, I should of posted this earlier but thought it a dead idea, as even I have sort of moved on from it :shrug:

These are some pics I took of my test hop in my M14......





As you can plainly see their is an arseing gert hole in the silicone, this I believe was caused by the BB dragging past the harder edge of my hop nub to the point of pulling chuncks of the silicone away :shrug:

Please bear in mind this is high grade building silicone, not the cheap shit you can buy for buttons down pound land/ dollar store.

If it does this to high grade silicone its definately going to do it to other, less durable products.

As an idea this method is sound, and to be honest its ok in use in the short term, as for a long term item I'd give it a miss and try some other more durable ( read harder) rubber, which I'll suspect will then not give the same grip that silicone gives :shrug:

To be honest the whole molding process, hap hazzard and inconsistent results on BB flight from the moulding is to much of a ball ache to warrent to much time and effort being expended on it :shrug:

It may well do, but there are far more easier ways to achieve better results in a shorter time :shrug:


The pics there are of my third attempt at even getting it to shoot straight, and when you add in the time of moulding, cureing and finishing each one, a process that that takes a couple of days at least, its just easier to make something else work :shrug:


I still use the basic principal in mine but I now embed actual hop rubber into the silicone as a friction surface and use the silicone as a bonder and sealer in 1, I also bond my hop rubber to the inner nub and barrel at the same time.

I do all this over a special former a spacers that I make to each barrel to ensure a perfect fit every time.


As to the original version of the J hop, like I said, a good idea in theory, I just dont think it met with my exacting standards :shrug: where it might meet with someone elses :yup:

So I finally found a quick and less time-consuming way to make these...
I'm sure someone has done this (what haven't you done Vindi???)
I just take a little time to make the oogoo (quite a pain in the a**) and piled it onto the window, using a cleaning rod wrapped in packing tape with lubricant sprayed on it inserted into the barrel (as per usual)
Now the hardest part for me was making it flush with the window; tried spit, grease, etc. with a razor blade, but the silicone that's taken off just sticks to more silicone....
So I sprayed some lube on a flat surface and rubbed it around on the area. I then rolled the barrel over that area (making sure to roll the barrel window over the lube) several times, squeezing excess oogoo from the sides, and the lubricant preventing any sticking to the surface of the flat... Surface...
The result was a very conforming top of the patch. Using a heatshrink bucking and square eraser nub I erected about only 180 feet of range with a CYMA Thompson with a barrel that definitely needed some TLC.
I haven't many buckings lying around and I can't afford to go grinding my precious few buckings, or I think my local shop owner is going to get peeved I keep coming for buckings >
Also tested with Elite Force .25 BIO's, which I have found to be not as well made as there non-bio BB's, which I love...
And if you make heatshrink buckings, I used the air nozzle inserted to create the appropriate sized bucking lip. Unfortunately, I melted my air nozzle by being careless with the flame.... So careful with that! Then wrap the heatshrink in appropriate amounts of teflon tape in line with eachother to ensure consistent pressure along the latitudinal portion of the bucking (although, with the stretching properties of teflon tape, the difference in pressure may be negligible.)
So in conclusion, I think it has potential. A tube of caulk and corn starch is cheaper than a pack of R-Hops, and you can make a ton of patches with these, and if you find that niche, you can output these pretty efficiently. Chunks may rip off after constant use, but again, if you find an easy way to make them, than it should be no problem to replace them.
