I have no idea. But I suspect 22 darts is likely to be the ceiling of being reasonable in terms of mag dimensions and spring load.

Replacing broken/ripped O-Rings

06 April 2017 - 08:27 AM

I wrote this out to answer this question elsewhere and thought it might be good to store it here.

 

IF you break/rip/tear and O-Ring and you need to find a replacement for it, here's how you can do so.

 

1. Use a ruler to measure the length of the broken o-ring piece inside of the curve.

2. Use that length with this calculator set to "Given C"  http://www.calculato...lane/circle.php

3. Write that number down as you now have the actual ID of the O-Ring (or close to it).

4. Measure the thickness of the O-Ring as best you can. This number will be close to either a fractional size, or a millimeter size. It's best if you can use a caliper to get this number, but a ruler with both inches and millimeters will do. Always make sure to round DOWN to the nearest fraction or millimeter since o-rings are oversized. For example a "3/16" cord width O-Ring is going to have a NOMINAL width of .210".

5. Write that number down.

6. Take both numbers and poke through the McMaster catalog in the o-ring section. You can find the nearest ACTUAL SIZE for Inner Diameter from their list as well as the ACTUAL (or fractional) cord width.

Just pick BUNA-N as your material for now. The majority of the o-rings used for Nerf are that material.

Now you have the DASH NUMBER of the o-ring you need. You can order the o-ring you need from McMaster, Amazon, Fastenal, or buy it from a hardware store. If you want to buy the o-ring from Home Depot you may need this chart to convert from DASH NUMBER sizes to the Danco brand o-ring part numbers.

Other brands may have different part numbers so check your nearest hardware store's online catalog before going to see what brand of o-rings they sell. If they don't list the products in DASH number sizes just e-mail the manufacturer and ask them for a similar conversion chart.


1995 Crossbow CAD Files

I haven't modeled the springs yet. I'll add them to the set soonish, then make the STL files available.

The internal parts are 100% measurement accurate. The shell however isn't exactly dimensionally perfect. It's been altered for improved strength and more compatibility with 3D printing (hopefully).
