Four hundred and twenty seven days ago, when I first decided to try hammer veneering I posted this hammer that I had just made for the joyous occasion. I had watched a few videos on youtube and read a few blogs and it looked like that was just what I needed. It was quite pretty and I was very proud of it.
Shift to present. Now I’ve done a fair bit of hammer veneering and discovered that there are subtlties in the design of a good hammer that had totally eluded me. The old one was too wide, it had too thick an edge, it wasn’t widest at the blade edge for getting into corners, and it was not well designed to apply big pressure with two hands. Besides all that, the lovely tight friction fit on the pretty brass blade opened up when it got wet and the blade kept falling out.
Since that time I’ve been using a series of make shift hammers. ( A small steel flatbar in a set of vice grips actually works amazingly well). Anyway, for whatever reason yesterday when I had some hammer veneering to do I made a new one incorporating some of the things I now know about veneer hammers.
It’s very simple, just a piece of angle steel from the hardware store and a bit of Osage Orange for a handle, but you can put lots of pressure down right where you need it. It’s hard to use the hammer with both hands and take the photo at the same time so imagine the heel of my left hand on the head of the hammer in photo #5.
Photos three, four and five show the basic gluing sequence:
First, apply glue to the substrate, here it’s MDF.
Second, place the veneer good side down and spread a coat of glue on it.
Third, flip the veneer over and hammer it down, working from the center out to the edges.
The one in the last photo works better than the pretty one but it can’t match my new best friend here. Maybe this will encourage some of you to try the “no bag” style of vacuum clamping.
Questions, comments etc. are always welcome
