*Support What We Do at The Katz-Moses Store* https://lddy.no/stih
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!

Links, Formula and Types of Wood PSI Needed Below:

*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
