In the first year of the birth of every high-end violin, I personally advocate using the leftover material from the violin panel to make the sound column, as the first sound column of this violin in the first year (generally speaking, high-end violins need to replace a new sound column after the first year of use, and at this time, the sound and synchronization of this violin will be greatly improved)

At present, many of the sound columns on violins are purchased in bulk. Perhaps their air drying and size meet the standards, but for a good violin, such standards are far from enough. So, personally, I do not recommend using finished sound columns purchased from outside for a new piano. And it should be taken from the expected panel of this violin (as mentioned above)

Split the appropriate panel on all four sides

Use a shovel to remove the edges and corners on all four sides

measurement

Use a file to continue removing its edges and corners

During this process, it is important to pay attention, measure more and do less. Excessive polishing results in material scrap, as there is not much leftover material for the panel

In the end, it can be measured with a thickness gauge for precision

Use a scraper to gradually round the sound column

During this period, it is still necessary to continuously measure with thickness instruments

From rough processing to fine processing, there are very rules, as can be seen from the sawdust on my desktop

polish

Complete large-scale tasks

Tools required for production

Finally, it is necessary to cut out the sloping surface at one end

Complete slope trimming

The most basic requirement for a sloping surface is to completely match the corresponding position of the sound column above the panel (no slight gaps are allowed)

Next, we are preparing to install the sound column
