I get many emails asking for certain belts for specific decks. I don’t have a backwards compatibility list. No one does! It seems like there are thousands of way to measure these belts too. Between measurements and deck types we have millions of possibilities.

SO! I decided to write a self help web page. This way if you need a belt you can send the dimensions to me. Takes all the guess work out, and helps insure that you get the correct belt. Please see the price list below. You will have to make your own measurements then email me with your needs. I will in turn send you an invoice, or a Paypal payment request. Its up to you.

Lets start with a square belt! (same dimension on all four sides)

1) Refer to the ruler below to acquire the first dimension: Use two pencils to hold the belt across the ruler but, DO NOT STRETCH the belt as you measure it! This is very important.

2) Measure and record the belts length. In this example the belt measures 6 inches.

4) Then you need to subtract 10% to compensate for stretching, and use of the old belt. 12" X 0.10 = 1.2" Now we take 12" – 1.2" = 10.8"

5) We now realize we need a 10.8" belt minimum. We could use any belt between 10.8 and 11.5 assuming the measurement was accurate.

6) Since we have a square belt, then we need to measure that too.

7) If you have a caliper, then this would be the best way to measure. Don’t worry to much about measuring them though. We can use common business cards. Each card is approximatly 0.015" thick. So you need at least two because they don't make belts that small. I would start with four cards though. Stack up the cards until they are at the same height as your belt. Use a flat surface, and press down on the cards while measuring! Then multiply the number of cards used. So if your belt is as high as three cards, then the formula would look like this 3 x 0.015 = 0.045 So now we have the second dimension. (10.8 X .045 square).

10) We measure and record the belt diameter exactly the same as step 2. In this example the belt measures 6 inches, B but we know to double this. The actual dimension is 12".

11) Once again we make the same adjustment we did in step 4. Take out 10%. Our new dimension for this example is 10.8"ID.

12) One major difference with a flat belt is an added dimension. We already measured the length, now we need the thickness and the width.

13) Lets start with the thickness: Use the same bussiness cards and the same methode we used in step 7. So now we have two dimentsions.

14) Lets get the final dimension (width): This can be measured with a ruler. Just measure across the flat surface.
