While one of the most significant achievements in turning in recent years has been the development of the four jaw Chuck for mounting wood for turning, the price tag on a good cartridge-it’s a shock for many Turners. In fact, the price for a decent four jaw Chuck is often attached prices for a starter machine. One of the things that a wood Turner should remember when going in faceplate turning to use the old fashioned glue block for holding wood.
Using a glue block occurs because of a desire not to have screw holes observed at the bottom of items such as cups and plates. As a rule, this point is the first rough turning it from green wood and then letting it dry in the shop for some time. Later she connected to the wood lathe and finish turned. In this remounting that it can be screwed to the front panel, while leaving holes in the finished product. Then these holes must be filled or covered in any way. In addition, the length of the screw defines a certain depth of wood that cannot be used or utility tap screws themselves.
Simple solution, and one centuries-old, is the use of a glue block to hold the wood to the lathe. First, the bottom of the bowl is aligned with the plane or other tool. Second, the block of waste wood screwed to the faceplate. Third the waste block is flattened. Thirdly, the waste block is glued to the bottom of the bowl using carpenter’s white glue.
As a rule, a piece of Kraft paper glued between the waste block and the bowl. This allows the bowl to finish turned and then a chisel blow between the block and the bowl splits the paper in the center. Then the waste paper can be sanded from the bottom of the Cup and the bottom is ready. If desired, the document can be removed from the Block waste and can be reused.
There are a few draw backs to this system. While the adhesive has a strong influence, but it must be clamped and let to dry for at least eight hours. In addition, the wood used should be dry, so this may not help with green lanes. In addition, the fuss of scraping glue and paper, a combination known for quickly clogging sand paper.
Fortunately, a few modern glues on top. When turning dry wood, such as dried bowl blank, hot glue can be used for bonding wood block to the bowl. Within a few minutes it is ready to be installed on the machine and turn on. Either unit can be divided with a clean with the lathe running, or the entire unit can be removed and the waste block removed with a sharp rap of the chisel at the glue line. Any glue residue is easily torn away from.
Similarly, medium thickness cyanoacrylate glue can be used for bonding green empty the unit of waste. Glue is applied to the waste block and accelerator to the empty and the two pressed against each other. Again, a few moments enough to hold work on the lathe and again a sharp blow on the glue seam will split after their turn is done.
Modern adhesive just let the old methods to work in today’s shops. And technology us some we are still working in historic fashion. The old ways are not always the best, but they certainly work and work well.
