I would like to lodge a formal complaint.

Pictures of Gordon in a dress... (how to measure fill thickness)

Made you look! Now read this:

Fill thickness, spread-ability and quality analysis

1.) Purpose and Scope:

This test method is to study the amount of of paintball fill spread as a measure of thickness and quality and to quantify the fill material based on spread-ability.

2.) Equipment and Materials:

  • Fisher brand filter paper – P5 type.
  • 5ml or 10ml Syringe.
  • Aluminum foil.
  • Digital scale.
  • Sharpie.
  • Ruler.
  • Timing device.

3.) Procedure:

  • Cut sections of aluminum foil that are larger than the filter paper.
  • Take a sampling of weights of the filter paper. Fisher P5 filter paper should have an average weight of 1.98g. Record the weight. The weight will be referred to as W1.
  • Number the filter paper with the sharpie. Each paper should have a unique identifying number and/or letters.
  • Measure and record the area of the filter paper with the ruler. The average area of the filter paper should be 280cm2 . Record the measured area as A1.
  • Place the filter paper onto the center of an aluminum foil sheet. Do not bend or fold the paper as the paper needs to be flat to avoid bias when spreading.
  • Draw fill from the paintball(s) you would like to test using the syringe. Drop exactly 20 drops onto the center of the filter paper. Each drop should be very close to 0.03 mg.
  • Wait 10 minutes after dropping the 20th drop. The fill should spread out uniformly over the filter paper in a circular fashion.
  • After ten minutes has elapsed remove the filter paper from the aluminum foil. Cut away the dry portion of the filter paper from the wet.
  • Weigh the remaining dry portion of the filter paper. Record this as W2.
  • Measure the diameter of the wet portion of the filter paper. If the fill did not spread in a circular fashion, take several measurements and average them. Determine the area of the wet portion. Record this as A2.

4.) Calculations:

There are two methods of determining the percentage of spread on the filter paper. Method one involves comparing both dry weights of the filter paper and the second is a measurement of the dry area of the paper. Both are independent of each other and can be used as a check method for accuracy.

Spread by weight

Dry weights reduce variables from the test fill. It is calculated as:

Spread Percentage = [(W1 – W2)/W1] Ʃ 100

Spread by area

Not as precise as the weighted test as the spread will not be perfectly circular. It is calculated as:

Spread Percentage = (A1/A2) * 100


Comparing the two spread percentages is as simple as averaging the two to get a final percentage. This is calculated as:

Average Spread Percentage = (Weight Percentage + Area Percentage) / 2

5.) Conclusions:

As a matter of discussion we can conclude that a higher spread percentage means that the fill is more dilute or will run more than a lower spread percentage. This however, is not an indication of the overall brightness or visibility of the fill.

Bryce, I need a template of the LSET. Can you repost in XLS?

WTB: Cheap Jerseys - Almost any condition

02 March 2011 - 04:09 AM

WTB CHEAP Paintball Jerseys.

I will consider any paintball company Jerseys in almost any condition. Jerseys can be any size, from skinny kids Jerseys to "holy shit how do you get through doors" size. Must be willing to ship (U.S. Postal service) to Canada. Payment made via Paypal in U.S. dollars or otherwise negotiated.

Seller must provide pictures and short description of the Jersey.

This is a great way to get rid of your old Jerseys. I will consider pants as well, depending on price.
