Introduction: TR-4 Buzzsaw Preview (internals Update)

Picture of TR-4 Buzzsaw Preview (internals Update)

Well before we even start I know what you're thinking. Where's the turret? Has JonnyBGood forgot some of the most basic knex gun deffinitions on this site? No I haven't and yes it is a turret, I just put a different spin on it (haha!). The turret is the rounded front part of the gun but instead of spinning perpendicular to the shooter, it spins towards the shooter. The front rounded part of the gun literally spins like a saw, thus the name buzzsaw. Now that I cleared things up a little lets look at some of the pros and cons:
Looks great (to me)
Trigger extends the length of the handle allowing you to use your entire hand to squeeze the trigger.
Sci-fi (with a capital S)
40 feet of range (using one rubberband that wasn't a 64)
New concept
4 blue rod capacity max
Cannot shoot larger ammo
Cannot be "dry fired"
Sometimes revolver does not stop spinning. (1 out of 5 trys)
It isn't anywhere near as easy to use as a standerd TR8
Does not offer any benefits in a knex war (besides looking good) XD
Uses two cut rods. (no I didn't use a buzzsaw to cut them either)
Anyway I'd love to know what you think about this gun so please leave a comment. Thanks!
Again I can't stress how surprised I am on the intrest people have in this gun!
Anyway you may also be able to weigh in on how I can make it work better as well. The problem I'm having right now is how to keep the turret section together. It is currently held together at two points the cut rods, well this worked with my old ammo locks but not with my new ones. The new ones solve the problem I was having with rods ricocheting off them when fired, but lack the structural integrity to hold the two revolver halves together. I added some image notes to the picture to clarify my lingo and also feel free to ask questions as always!

Wow I'm really suprised at the amount of intrest in this gun! I thought you all were going to think I was crazy. Seriously. I am working on internals and a video currently, if all goes as planned expect a full ible this weekend (also depending when I finish working out one last little problem). I'll keep you updated

akshat21045 (author)JonnyBGood2014-01-22

If I were to give you an idea; why don't you share the problem in the gun so that some other gun modders (Red, Dr. Richtofen, FlyingFish, me etc.) can help you in solving that problem? It could be a success!

JonnyBGood (author)akshat210452014-01-23

Well pics of my technical and problematic area are up! Feel free to give advice or suggestions.

Kona-chan (author)2015-03-29

I remember making this into a meelee weapon :') *sniff*

oodalumps (author)2014-02-19

That's a very unique design. I like it.

JonnyBGood (author)oodalumps2014-02-19


DJ Radio (author)2014-02-18

That's a radical design. My jaw dropped. Makes me want to get back into knexing.

JonnyBGood (author)DJ Radio2014-02-19

Well thanks! I hope you do start knexing again. There's just so many ideas that people haven't tried yet so I'm trying to build them. This wasn't too hard, you must need to look at common styles differently.

DJ Radio (author)JonnyBGood2014-02-19

I've been out of the game for a long time dude, and college is right around the corner. I don't even have any knex where I live right now lol, I left all of it at mom's place.

JonnyBGood (author)DJ Radio2014-02-19

Well that sucks..... I'm a sophmore in college as well so time is always an issue.

Kona-chan (author)2014-01-29

where's the trigger mech?

JonnyBGood (author)Kona-chan2014-01-30

Well it's not pictured but it's very generic. You can refer to the mech in Competitor IV for internals but the trigger extends the entire length of the handle.

Does that help clarify things?

Kona-chan (author)2014-01-28

trigger, where's the trigger?

Knex Lego Maniac (author)2014-01-27

Jonny not sure what took me so long to take notice but man what a fun concept! I can see some huge potential possibilities with this concept. Awesome work man!

Kona-chan (author)2014-01-23

hmmm me liky

but you can make it into a meelee weapon, with some mods,

if you want i can try to make it more, meelee'ish

JonnyBGood (author)Kona-chan2014-01-23

Well this gun could be a great meelee weapon. I'm thinking that you're thinking along the lines of a saw based weapon? Shoot and slice? Feel free to make a more meleeish version!

Kona-chan (author)JonnyBGood2014-01-27

i can't make it

dunno how the tigger works bro :s

Kona-chan (author)JonnyBGood2014-01-25

not shooting, just a buzzsaw that kills people :3

but then i'll need instruc.. oh u posted internals,

right away

akshat21045 (author)2014-01-23

Ok, so I now see the main problem. The mag is not locking because of the small mag lock. I would suggest to make it slightly larger for better locking.

Also, would you mind sharing the internal pics of the trigger? I really like the new trigger style.

JonnyBGood (author)akshat210452014-01-23

well the mag locks work fine. The entire revolver portion of the gun will split apart sometimes and that is the major issue.

akshat21045 (author)JonnyBGood2014-01-24

What do mean by split apart, BTW?

JonnyBGood (author)akshat210452014-01-24

Well since the two halves of the revolver are only held together by the two cut rods they tend to seperate because the cut rods won't prevent them from sliding apart. Luckily though I have found a solution so I'll try it out as soon as I have time to work on it. I still plan to post this gun this weekend.

akshat21045 (author)JonnyBGood2014-01-24

That's good. I'm waiting for the instructions!

JonnyBGood (author)akshat210452014-01-24

Alright! I can't help but notice that nobody seems particularly interested in the internals, maybe this wasn't what they thought it was. Did I describe it wrong or do they still don't get how it works?

akshat21045 (author)JonnyBGood2014-01-24

Yeah, It's a totally new mech. Everybody was, I guess expecting the same-old mech. So, they might be surprised.

JonnyBGood (author)akshat210452014-01-23

The trigger mech is really just a standard mech I used in zip2 and Competitor VI the trgger itself is just longer.

akshat21045 (author)JonnyBGood2014-01-24


JonnyBGood (author)akshat210452014-01-24

Yea.. it also reminds me of the price guns I use at work. (As seen in my first ever forum topic)

First off, I just want to say that this is your best looking gun yet. It is not messy (not that any of your other guns were), and is really uniform and clean (hence the "not messy"). I don't quite understand how the mech works, so some internal pics or a video would be great. Good job bro, I am looking forward to more of your stuff! BTW, is it semi-auto?

Well I'm absolutely flattered that you like it! =D It did come together really nicely.(Just as the image in my head) The mech isn't super new it really is just a turret that spins parallel to the shooter. It isn't semi auto either, just your average pin. It would be really awesome as a semiauto.

Maybe a better way to describe the unique feature of the gun is like this. See the rubber band that is stretched down the side of the gun? That spins the turret on the gun. It's just spinning in a different direction. I'll make a video for you tomorrow too. I'm still tweaking it a little mechanic-wise but it's look won't change.
Anyway thanks again! (Jeez I got to have a record for the longest average comments)

Oh, I see. Well, the only reason I asked is because I can't seem to get how the mech works, so I thought it might be semi-auto. I can't wait to see the video and the finished product! Are you planning on posting?

Yep I plan to post because someone wants and ible', still tweaking the mech so the revolvig pat works correctly. The video is late as you see (my bad) I'll get some internals up when I get home tonight.

Sounds great, and I await the video and internals!

Internals are posted now!

I saw them, and they look really interesting. This technically could rival a b/a gun... This is really nice!

Well it is pretty much a revolver, like a TR, but thanks!

akshat21045 (author)2014-01-20

Hmmm, I my opinion, this gun is a really good one. Not to mention the second best looking gun on this sight! It is surely compact and is simply said as AWESOME. If you don't mind, I am gonna give you some more trouble by asking you to post this. (BTW, does it use chain links and a motor? If not then how do you get the turret to revolve?)

XD, what is the best looking gun on this site, in your opnioin?

Definitely your SL8. It was seriously unbeatable in the looks part!

Really? I think that many of my other guns look much better, at least aesthetically. For example, I think that Declaration is a much better looking gun. I am glad you like the SL8 though!

OK, I take it back. R5 is the best, SL8 is the second and sorry Jonny, this is the third... Really man how do you get ideas? I am still stuck at what to make.

Really? Wow, what a high complemetn. All I can say is that I try. =D

JonnyBGood (author)akshat210452014-01-20

Thanks! Glad you really like it! I'm still working on one final glitch in the mech (that revolver not being stopped poblem) but I'll work on posting after that. =D
It currently revolves using a rubberband although I may use a small "pullback" motor on mine. Other than that it doesn't use any special pieces.
Regardless this will be posted! I'll see if I can get it posted this weekend, due to school.

akshat21045 (author)JonnyBGood2014-01-20

If you are to post it, please do so without the motor (My motor came defective). Otherwise, it sounds good to me!

JonnyBGood (author)akshat210452014-01-21

Well it was going to use a spring motor ( not electrical )
but yeah i was going to post it with a rubberband power source for the general knex community. Everyone has rubberbands! I plan to get some internal pictures up tonight and I plan to post this weekend (because I'm still trying to make the mech work perfectly).

didexo (author)2014-01-23

Wow, the internals were completely different form what I expected. None the less, great build!

JonnyBGood (author)didexo2014-01-23

Thanks! What were you expecting?

didexo (author)JonnyBGood2014-01-24

Not sure exactly, I though the bullets would be fed in a different way. Nothing really specific.

sandroknexmaster (author)2014-01-22

I've never seen anything like this! Cool concept, can't wait for the vid :)
