Making a Veg Tan Leather Belt 

Thanks so much Tait!

Wow thank you!

Thanks!

Thank you Rosa!

Thanks Chris!

Ah! This is what I've been looking for! Is there a good formula to calculate it? I make belts that often have a lot of O rings and have been having trouble getting the right size for people. (I'm in Australia, so we don't use ounces, the leather i get is normally 2.7mm or 3.5mm thick)

*Internal circumference* is the measurement you need to know for the final size. Most people measure the *outside* and do not account for the most important - the *internal.* It's no different than people - their *inside* measurement (character) is what matters, not the external size, appearance, or claimed features.😉

Just for reference - the difference between the inside radius and outside radius caused by the thickness is simple "2*pi*thickness" so roughly ~6.5 times thickness. Even with thick leather ( 5 mm, 12 oz ) the difference is not much, like 3cm, 1.5 inches. And that is the maximum difference, in reality it will be smaller as the inside of the belt is compressed but the outside stretched a little, so more like 4-5 times thickness.

Agreed, a beautiful quality belt gets better with age [if well looked after, oiled & burnished]

Good luck with it! Thanks Varoon

haha glad to hear it!

Thanks Fadi! Good luck

Similar to plumbing: *inner* and outer *diameter measurements* on pipes & fittings. *Belts,* when applied around a waist, are essentially similar to a "short length pipe" and *have to be measured internally* in the same way, regardless of wall diameter (material thickness).

Stoney327 >There is an easy ‘methification’ to solve your expansion dilemma on the belts... (1 / 64 x Oz ) x L + OD = final length needed to cut for belt to fit properly... in other words.. your using 8 oz leather, leather is measured in 1/64ths per ounce for purposes of thickness, so you multiply 1/64th x ‘Oz’) or Thickness in ounces, then multiply that result times the necessary final size needed.. let’s say 40” for a big fella, now add THAT RESULT (in this case 5”) to the 40” fo a total of 45”..BUT WAIT!!! That’s just enough to make it around and touch ends! A lousy belt to be sure! So you add your desired length for buckle attachment at one end and holes at the other..say 4” for the buckle end and 6”-8” (depending on customers desires and weight fluctuations!) so your needed length would be 55”-57” total length! This comes up in clothing all the time. If the customer finds the edge smooth and comfy they might wear the belt tighter and under their belly flop but if the edge is slightly rough and irritating causing them to wear it over the belly adding a necessary 10”-20” to the needed design... I go to fairs and cut custom belts of up to 100”+/- and can sell them for $150.00 but they must be at least 10 ounce by 2” wide without blemish in order to hold the.....stresses....put to them! That’s a price with minimal decor, pressed initials and a couple carved roses. These guys know the big and tall stores can’t beat the quality or the price!

Over complicated explanation as clear as mud to the non nerdy type, written like a true engineer ;). Coming from an engineering student interning through school

Thank you Greg!

haha thanks Paul!
