  • The whole construction process of "Pit Vipers"

    I still remember when I saw Paul's "Pit Vipers" design plan on the forum in early May 2022. At the first sight, I knew that this was what I needed. I had to build it, but my living room couldn't put it down. I returned to the place where my parents lived soon after the outbreak of the epidemic, and the special plane was ready for me to build it. In the following period of time, he closely followed the progress of the project until the end of July when Paul finally released the complete construction information. Thank you. Thank you again to Paul for providing us with such a good design. I like it very much. During this period, I have started to search and purchase parts. In July this year, I left my original residence and returned to the city where my parents lived. The original woodworking tools and table saws could not be brought to my parents' side. This makes it impossible for me to carry out precise cutting of boards. Because of the house, I am not allowed to do large-scale woodworking, which will cause a lot of dust. I can only find the business that provides CNC cutting, and send my sheet CAD drawings to the business, so that they can send them to my home after cutting.

    After July, I was busy with many things at home, and finally got my box materials at the end of October. OK, we can start. Of course, before that, I had purchased speakers from soundimports in July.​

    I spent the whole afternoon to complete the layout of CAD, which was very tight and did not waste any materials. When I finally got the plate, I found that I had made an additional internal support frame. That is, there is one more red frame bracket in the picture. All right, more is more, put it at home. I used two 18mm thick high-density boards to cut a pair of speakers, which was just right.

          I will fix it with screws first. After I have pasted it with glue, I will remove the screws and fix it with wood tips.
          I used an 8mm wood chip

            First, I use screws to position the outer frame and the inner bracket, and fix them. Then, use glue to paste after disassembling, use screws to fix, and combine with F clamp. This method can make up for my lack of F fixture. Of course, there will be no displacement at the joint of the board after the glue is applied.

                For the middle speaker body, I still use the PVC pipe cap. I added a wood circle on the pipe cap to reinforce the PVC pipe cap. The diameter of the pipe cap is 171.5mm, and the inner diameter of my circle is 172mm. It looks larger, but the actual gap is too small to cover it. I used simple tools for quick polishing.

                When you make it, I would suggest adjusting the internal force of the circle to 173-174mm, which will be very stable under the reinforcement of glue.

                  It took me one afternoon to finish polishing, and the inlay was perfect. My speaker panel is a double-layer 18mm density board, so the pipe cap and the board are parallel.

                      I'm doing some construction today. Share more pictures to everyone and put forward your opinions. I need to make plans for the next step in this period of time
