I hope the following answers are useful to you.

1, according to the past practice, many curved wood edges (wood lines) are made by sawing small holes with straight wood lines and then bending them into the required radian. This will leave many ugly holes in the wood grain. According to the traditional practice, brush them with putty and they are finished. For the finished product, it will be ugly after varnishing, even if it is done in detail, it will be ugly after 1-2 years. If it is mixed oil, it needs very fine treatment to avoid it, but it won't last long.

2. With the development of the construction industry, various beautiful wooden lines and frames have appeared in recent years, so that the final requirements can be achieved only by construction and installation. If you don't need to replace the glass or the board core in the future, you can achieve the perfect effect by mixing the glue with the mosquito nail gun.
