This week I have been working on a marquetry panel for another “Make a Chair from an Oar” project.
Here is a picture of the essentially completed panel that I rubbed with some paint thinner to pop the grain a bit.
It is an iconic Canadian image. (answer at the end of this post)
For the most part, all went well. But I did encounter some challenges with the glue up.
I’ve got some questions and I’m hoping to get some advice from those of you who are more experienced with marquetry.
I’ve read some books, watched some U Tube videos and read various blogs when posted. Some of my questions may have already been covered in a blog or post but there is so much info that it can get overwhelming. If you can point me to a specific post or resource that may cover my questions that would be helpful and appreciated.
Once I had finished cutting etc. I covered the show face of the panel with moistened veneer tape. Then I carefully removed the blue masking tape from the back side of the panel.
I find that the veneer tape does not adhere to all parts of the panel and as I remove the blue tape pieces pull away. To address this I rub white glue on these parts to stick then back down. Am I not wetting the venner tape enough, wetting it too much?
Question 1: I recall reading somewhere that hide glue is applied to the face side of the veneer then covered with paper. Is this an alternative to using veneer tape? Does it stick more evenly? Can it be down with “liquid hide glue”
Once all the blue tape was removed I prepared to glue my marquetry panel to two other pieces of veneer, each piece with the grain running in opposite directions. I applied white glue to each of the backer pieces and stuck my marquetry panel on. On either side of the assembly, I placed wax paper, then a couple sheets of a heavy bond paper. I put this between the cauls of my my veneer press.
When I removed the assembly from the press black spots had developed on the lighter coloured veneers. Fortunately I was able to sand most of this away.
Question 2: I have read that this may be mould caused by leaving the assembly in the press too long. Is this the case? I had it in there about 4 hours.
Is it also possible that the black (dyed?) veneer border bled into the lighter wood?
So what should one do to prevent this from happening again?
Question 3: I’m not sure I’m ready to go the full hot hide glue route. However are there advantages to using liquid hide glue over white glue for this glue up. Can you point me to a good resource on how to do this with liquid hide glue?
Question 4: At the top of the lighthouse there is supposed to be a railing. I was not comfortable cutting in such fine lines with the fret saw or with a knife. Would it be advisable to cut the lines in with a small V-gouge (or knife) and then with coloured epoxy fill in the the grooves created? I would like to add this detail, but I can live without the railing if there is a high probability of ruining the picture by trying to add it.
Any advice you can offer is very much appreciated.
