First, the function of such a table. My requirement was a table saw, a saw blade to the working exactly vertical. The table saw cuts in supplies about 45 ° angle, while etc. only can produce clean with a rectangular cutter or blade grooves. This is the central purpose, for everything else there are better devices. I have a table saw, a circular saw, a miter saw, a handsaw, a jigsaw and a chain saw, and none of these tools can replace one of the other. In particular, the idea that a table jigsaw could replace a table saw, is simply ridiculous.
For this reason, the guide stop, which comes with the Neutechnik saw table, for me is not important. I would say it is more than a toy, and less than a serious work guide. This track can not be very high load.
The Neutechnik table has a big advantage over the self-built table. This is the blade guide (between wheels) that prevents bending the blade. For the intended purpose, which makes the saw more for milling, this accuracy is very important and allows fast working.
This advantage is paid dearly: the lead due to the (red) bracket, and in turn prevents free work on workpieces that are longer than 15cm (if it just has to be the direction or location). On self-built table I have free rein in all directions.
The second disadvantage compared to the self-built table: the Neutechnik device is not a table. It is clamped to a workbench. This means, firstly, that it hangs in the way and after working the same has to be dismantled, but what is worse, the "table" vibrates strongly, if one really gets going at maximum speed. When milling small slots occurs not on, but if you actually edited times a 10mm plate in curve section, you have to hold the workpiece with great effort.
I myself am pleased with my purchase: material and processing of Neutechnik device are good, and if I need a precise blade guide, I have what I need. I am using the combo of Jigsaw and "saw table" only when it is unavoidable - because of the expense for assembly and disassembly, and because of vibration - but I did not expect to get the eiersägende Wollschnittsau.
