Great questions and input here about Lamello Zeta and Clamex P connectors. I am the Lamello product manager for Colonial Saw Co. / Lamello USA. I want to let you know about a new product for use with the Zeta P system, it is "Tenso" P-14, Tenso joining system works similar to Clamex P in that they are fast and slide into the same slot made by Zeta biscuit joiner. Tenso is a glueing aid that allows you to clamp glued edges without typical mechanical clamps, Tenso draw parts together tightly and holds your parts together while glue cures. Tenso is very fast and easy to use. There is no need to come back and unclamp anything, Tenso stays inside the wood unseen. Tenso allows for more space in the shop to utilized. Assembled items can go out the door sooner. . And... Tenso glueing connectors do NOT require the 6 mm hole that was mentioned here about Clamex-P connectors. Tenso is totally invisible after installation. More about Tenso at the web link below...

Gus mentioned that it would be nice to play with a Zeta for a week before investing in one. We actually have a program for that.. We will loan you a Zeta to use, you simply need purchase the P system connectors you will use for your trial, and there is no cost to use the Zeta for a week or two. If you like what it does, you can order yourself a Zeta, if it does not work for your application, simply return it. For more information please contact me...
