In This week’s woodworking skill builder we’re talking about clamping pressure, what types of clamps I use and where I get them. We go over the formula for clamping pressure and how many to use on different types of wood. Links, different types of wood psi needed and formula below. I really can’t wait to see what you create! Let me know what you’d like to see next. Thanks for watching! Please like, comment and subscribe. Cheers!

*Clamps Main Page( qty discounts are big fyi):* https://lddy.no/m61p
*Parallel Clamps:* https://lddy.no/m61q
*F-StyleClamps (bar clamps):* https://lddy.no/m61s
*Pipe Clamps:* https://lddy.no/m61u
*Bottom Line: Use More Than You Need. Don’t Get Hung Up On Trying to Calculate to Use the Least Amount. More Clamps, Less Stress*
*Formula:*
(Glue Surface Area X PSI Needed) / Clamp PSI = Clamps Needed (Then Divide By Length of Clamping Pressure at Glue Line)
¼ Sawn First # in PSI and Flat Sawn 2nd # in PSI
Pine: 150 , 300
Cherry: 250, 500
Walnut: 300, 600
Oak: 450,900
Maple: 600, 1200
