Finished my first +bow. I need to ask my Design Technology teacher about access to one of the CNC mills my school has. If I can get it, expect a few more that will be up for sale at some point.

[Draconis]

I officially dislike cutting nylon rod on a scroll saw. I think the speed was up too high, because it kept melting back together and binding. Otherwise, construction on my first +Bow is going well! I have never worked with Polycarbonate before, but it really does machine beautifully. I'll edit in a picture of the completed assembly soon. Thanks for the design CaptainSlug!

You have the speed set too high and probably don't have the air pump setup. You will probably get better results with a mitre box.

My new Pride and Joy. This was made by Slug.


Came with this a Slide breech with I put PETG in.

Some fun pictures of the process:


2 +Bow and 1.5 L+L laid out on one 12x12 1/4" and 2 12x12 1/8" sheets


The parts all jumbled after being cut out


Everything all nice and ready for assembly


And the results. No, I didn't make 4 out of the templates above, I made 2, I had one cut already and I had one completed already.

I need help with my plusbow, with my too tight cpvc I'm only getting about 90 feet and it has a PVC plunger tube which I'm replacing soon, will using brass and replacing the plunger tube get it up into the 130-140 range?

It's actually polypropylene, and dart fit/weight is crucial to those kind of ranges. The same lightweight stefans you use in a nightfinder are not heavy enough to fly that far.

Your problem is your barrel and your darts. Replacing something unrelated won't help.

Your problem is your barrel and your darts. Replacing something unrelated won't help.

So the dart fit in the barrel will have the most effect on range?

It can, yes. With a bad dart/barrel fit you can easily get 80ft or even 70ft ranges from a +Bow that can get 100+ft with a good dart/barrel fit.

Yeah. Nobody ever claimed they were getting 130-140 feet with a poorly matched dart and barrel combination.

[perezinthenet]

Should I expect that kind of range once I find a good dart/ barrel fit?

Don't EXPECT anything specific beyond just an improvement.
Range figures are a ballpark of the results a person is getting with THEIR blaster, barrel, and darts. They're not a guarantee since you, in all likelihood, won't be using exactly the same everything as that person.

I just received all of the parts in the mail.
All I need is a new blade for my band saw and I'll be set.
While looking through the plans I couldn't find how long the plunger rod is supposed to be.
How much space would be between the two end lables of the plunger rod?
What brand of silicon lubricant do you recommend?
Also I don't have labeling paper, could I just use a glue stick or something to glue the paper templates to the protective covering of the plastic?
EDIT: Would using a hand held jigsaw to cut the plastic work?
Thanks in advance.

hey i'm thinking about doing this so how much does making this gun cost and how far does it really fire because i can't take uin13's ranges seriously

depends on your barrel and dart fit, but it does get well over 100 ft. Trust me, his ranges are accurate.

If you actually READ the instructions you will see how much it costs and what tools are required.

Of course if this becomes too much for you, you can always buy one of mine.

The ranges are easily 100+', and at that point, who cares? It's long enough. It's never going to be accurate past about 120-130 in any case, and if you have visions of being a hilltop camper, forget it. Nerf is not about campers.

[NerfDude1138]

I have completed my first +bow Rev2. Nothing fancy, just followed Slug's instructions. I love it. Many kudos to Slug for his design.

INSERT PICS HERE

Many kudos. That is one of the cleanest +bows I've seen other than Slug's. Really nice work.

Does the thickness tolerance matter if the thickness is 1/4 and 1/8? In the above picture the polycarbonate is not the same part# as the one on the part list. Correct? I would prefer if CS replied to this. Thanks.

Edit: Replying to your post Splitlip, does it matter what kind of polycarbonate you order from Mcmaster just as long it's 1/4 and 1/8 in thickness?

Edited by Hoceky, 23 February 2009 - 12:33 AM.

[Split]

Then PM him.. Otherwise, I'm going to tell you the answer if I know it. The polycarbonate on the +bow you quoted is the same as in the parts list, aside from the smoke tinted section in the stock. It's just lightly sanded, as recommended in the writeup.

Just finished this...

[Daniel Beaver]

Yum. Looking forward to seeing that in person.

[spartan062]

Would 3/8" plexiglass work? or would that be too thick?

[analogkid]

No, Plexiglass usually refers to acrylic if I remember correctly. Acrylic is a whole different type of plastic that is much less impact resistant than polycarbonate. Just use what's on the parts list.

[Draconis]

That is correct, Analog. Lexan is a brand of Polycarbonate that is widely available. To address the real question, though, 3/8" is WAY too thick for anything but plunger rods. The design is around specifically dimensioned components that cannot be altered without altering everything else.
