Good morning/afternoon/evening There is a pretty obvious color difference between the back of my violin and the sides/top. This is the first violin that I am making so at the time that I had ordered a set of tonewood from Alpine Tone Wood, to make my violin I didn't really pay much attention to the color difference between the back and the top. As you can clearly tell from the pictures the back is quite brown compared to the sides and the top. So I wanted to ask you, if is there any way to reduce the color difference so that when the violin is finished, this difference will be either eliminated or very mild? Staining the top and sides or putting less brown color when varnishing the back, are the first things that come to my mind but I would like a more informed opinion on this matter. By the way any comments on my violin that could help me for the next one will also be very much appreciated Here are the pictures where you can also see the color difference:
Hi, I am an amateur maker, having completed a course of violin making at South Thames College in Morden Surrey. I am currently completing a viola and I would like to tan the wood (spruce front, maple back) using a UV chamber. I have constructed a cabinet which I have lined with cooking foil. A small electric motor rotates the instrument one revolution per minute to provide uniform drying/ tanning and there are three 18watt UV lamps. So far I have tried test pieces of maple only, but after 48 hours there is no distinguishable difference in colour. The three UV lamps are 60cm 18w Actinic fluorescent tubes, distributed evenly around the cabinet. They are intended for insect traps. My question is whether these are the wrong type or simply not providing enough total power - or whether I should expect to have to wait longer. Foggy
I think with this post I have reached my quota for the day. I have noticed that wood left in the window for a while tans nicely. Does the window glass -- untinted, no UV protection -- enhance the oxidation process? If the answer is yes, might we put our fiddles under large fish tanks to better effect? Or David Copperfield's water tank used for feats of magical escape?
