Hello LJ members & friends,

I’m in the process of having an intaglio etching press built…and the press bed is normally made of 1” thick steel.
There are options…and I want to build one like a Takach etching press bed; (type Takach in browser and see it).
Anyway…it’s made of rock maple, 3” thick, 24” wide X 40” long. The bed is glued and held together by 3/4” steel
rods and end plates. The top and bottom is also covered with 1/4” thick 6061-T6 (aircraft aluminum) and another final layer of phenolic resin thin sheeting.
The Takach site says “staggered” grain…and I’m not sure what that means. Also…is rock maple 1 species….or are
there others to consider. This press bed will be under tremendous vertical pressure with a 6” diameter roller. There is also a lower roller (smaller dia. 4”) and the wooden press bed travels between these 2 rollers.

If anyone can enlighten me on this project or make any recommendations as to wood species or other details, I’d greatly appreciate all thoughts.

Thanks,....and GO PATRIOTS !!!

For info on wood species try woodfinder then check at Maple.

This may be what “staggered” mean. Just a guess.

hmmm…I’m thinking it’s each layer (5) is cross grained; layer 1…long wise, layer 2…short pieces perpendicular, layer 3…long and so on. All good Steinway pianos (or even all pianos) have what is called a “pin board” which is most commonly made from rock maple.That is a very high end use of “staggered grain” construction. I contacted the etching press company (Takach) as theirs is rock maple and staggered grain. His reply was the cost of the bed would be just over 2,000.00 !! I’m sure I’ll be able to make it for a fraction of that…probably around 800.00.
Lumber prices here in the Northeast are quite high. Perhaps a road trip to Maine might get me much better prices.
I’ll have to check around…the beauty of the internet.
Thanks for your thoughts..and keep makin’ sawdust and above all…stay SAFE !
