Well, I completed my journey and this is my story. I decided to use the maple veneer Karson gave me for the border of the chest board. Here is a picture of it taped up from the back:
The next task was to completely tape the seams with the three hole tape as seen here:
This was a somewhat tedious job because of all the seams. I felt that the mitered corners came out quite well and I was getting excited about finishing the process of gluing it up. I did a test piece with some of the burl on a scrap piece of pine. When I coated it with the glue it became obvious that the burl had many small holes that would allow the glue to seep through. To stop this so that I didn’t end up with a strip of veneer sandwiched between two boards, I covered it with the painters tape before clamping another piece of pine over it. The next day I was quite pleased with the outcome. The burl was glued on flat and the painter’s tape kept the glue from seeping through to the other board. Now that I had proved that this method worked, I was ready to glue up the veneer to the MDF. I applied painter’s tape over all the burl and any small cracks that were evident in the seams. What a job! I applied Titebond II to the MDF and spread it nice and even across the whole surface. I taped on side of the veneer to one side of the MDF so that I could flip it over onto the glue. I worked my way from the end closest to the taped end across the MDF with my wooden roller making sure that the veneer was mated flat to it. I then took another board of MDF and clamped it on top of the veneer using cauls to equalize the pressure applied across the entire surface without applying too much pressure. Just enough to get a little squeeze out. The next day I removed the clamps and noticed that the maple border had a couple of spots that were bubbled up and a few of the maple squares were in the same shape. Needles to say I wasn’t happy with my results after my test piece worked so well. My next discouragement came when I began the process of removing the three hole tape. I used a sponge dampened just enough to dampen the tape as was described in material I read about veneering. I started to remove the tape which was coming off nicely, when I notice more wrinkling of the maple veneer squares and border. :^( Now what was I to do? I had to get the tape off and this was the process in which to do it. I continued removing the tape and as I did I tried to think of what I could try to fix this mess. I decided to try using an iron to heat the veneer, thus removing the moisture and hopefully getting the glue to reactivate. Well the veneer started to lay down, but it was turning color. The iron was set too high! I turned it down and tried again. The glue started letting go and I could see that this was going to get worse before it got better, so I canned the idea of using the iron. I sanded the darkened veneer and tried rolling it with my wooden roller hoping that as it cooled that the glue would hold. Well, I think I was back to where I started. I finished removing the tape. Afterward, I decided to put the veneered piece on the driveway direct sun light hoping it would dry the veneer allowing it to flatten out. I seemed to work somewhat, but not perfectly. I then decided that while it was flatter to go ahead and seal it with several coats of poly. I seal the back of the MDF with shellac. I brought it into the house hoping the the air conditioner would further drop the humidity in the veneer. Well, I’ll let you be the judge. Of course, there is still some bubbled spots that the camera doesn’t show and one spot along the border and the edge of the substrate that didn’t hold. I will re-glue it. My only solution it to put 1/8” acrylic over the entire board so that the chess pieces will not be affected by the bubbling. Here is what it looks like:
Any suggestions from my more experienced veneerer’s on how to avoid this in the future and what it is I did wrong would be greatly appreciated. I plan to make this into a table with a drawer as a completed project in the near future and will post when I finish it.
