It was really fun, so let's just do it again on my Birthday. I kind of wanted to do one sooner, but July and August are usually just too damn hot.

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.


STEP 214 Format: http://captainslug.c.../Crossbow95.zip (2.6mb)

Exterior DXF: http://captainslug.c.../Crossbow95.dxf

Cutaway DXF: http://captainslug.c...bow95inside.dxf



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).

Replacement PAS Trigger

Uses an extension spring rather than the original and annoying torsion spring. Made out of 1/4" polycarbonate (which is typically .230" thick).
