Sandpaper

First, scrape off any rough parts on the outside of the horn. You can use a sharp knife or piece of broken glass (leather workers use a piece of glass to scrape leather - it works the best on horns too). Steel Wool rough/fine/super-fine Steel Wool rough/fine/super-fine Now take a piece of rough steel wool (not S.O.S. steel wool pads, they will stain your horn) or fine sand paper and carefully (and gently) sand the outside of your horn. Again, take your time and work carefully. Gently buff your horn with the steel wool or fine sandpaper until it is smooth. Gradually use a finer grade of steel wool or very fine sandpaper to make the outside of your horn even smoother. There are no shortcuts, just take your time. There will be scratches as you sand, these will be removed with an even finer grade of steel wool or sand paper. Jeweler 's cloth Jeweler 's cloth Once you have made the outside of your horn smooth from the finest grade of steel wool or sandpaper, take a jeweler 's cloth and polish it until you have a mirror like surface. You can use the Jeweler 's cloth to polish it after you finished it as well to get an even shinier finish. Plus Shine and polish your jewelry. I love these cloths. Lining and Sealing the inside of your Horn (Optional) If you do not wish to line and seal your horn, then skip to the section: "Curing Your Horn" Some people like to line and seal the inside of their drinking horns. This is a personal choice and even sparks debate between…

Experiment 1.) When I rubbed my fingers over the sandpaper the coarseness was a 5 on scale of 7. After two min wait the coarseness is a little soft and I would say it felt like a 2 on a scale of 7. My perception change because I honestly though that the sand paper would stay the same. Looking back I guess I should have known because I did go over the sandpaper a couple of times. By doing that I allow my fingers to weaken the sandpaper. 2.) What surprise me is that some of the sugar was still in…

multiple surfaces were cardboard, sandpaper, rubber and cork. My hypothesis experimented that the block of wood had many factors that determine the friction of the four surfaces would be the material, normal force and that static friction is way greater than kinetic…

percent difference was60.78%, over half (50%) but not by much. For weight off sandpaper the difference was only 40.00%, where on sandpaper it went up to 45.71%. Still less than half meaning it does not have much effect on the level of friction on the block of wood. Conclusion: In conclusion this lab it did meet the purpose, as it was discovered that surface area (due to the percent difference) affect levels of friction more than surface texture and weight. Sources of error for this lab are…

multiple blocks across different surfaces and finding the difference in friction. 4.3 was about pulling blocks but in a bigger surfaces area. In Lab 4.1 we had to pull different blocks across different surfaces. The surfaces were a tabletop, wax paper, paper towel, fine sandpaper, and coarse sandpaper. In order we had to pull a wood block over those surfaces 4 times. And then after that we had to get the averages and put them into a bar graph. Tabletop average was 0.62 newtons. Wax paper’s…

The results of the experiment was that the worm went toward the water all 3 times. I accept my hypothesis because I correctly predicted that the worm would go to the water. Two possible errors in the experiment is that the paper towels with the substances were not completely flat, and that the saltwater might not have been as salty as water you would find in the ocean. Two improvements would have been to flatten the paper towels, and to get water from the ocean. The final hypothesis is that if…

would take the golf ball to hit the floor after it was let go. We performed three trials for each ramp and recorded our times in the data table. We were to repeat this step for the other measured distances along the ramp including 30 cm, 60 cm, and 100 cm. Erin Jones and I hypothesized that the higher the plane, the paster the golfball would go down it. I also thought that the smoother the surface, the faster the acceleration. We thought that both of these things would contribute to how fast the…

made by combining nitrocellulose and plasticizers with color pigments. The mixing is done in a “two roll” speed mill that increases speed as the pigment is ground down. The final result is a production of fine dispersion of color. Once the pigment is prepared, it is mixed with solvent in a stainless steel kettle. The kettle has a water-jacket that allows the mixture to cool. Once the mixture has cooled off the polish is ready to be placed into bottles. Besides the polish, another starring…

counting, and spindle box. While counting the number of classmates at circle, she is able to count to 15. One of her favorite activities is working with the 0 – 9 bead bars, counting the beads on each bead bar. Tvisha also loves to explore the spindle box and teen bead bar. She will continue to develop her knowledge of numbers and their respective symbols next semester. We look forward to supporting her mathematical awareness. January Comment: Tvisha enjoys learning letter sounds using the…

firearms cosmetic appearance. The purpose behind cold bluing firearms is improvement. The cold bluing process, is an inexpensive way to repair; older, rusting or blemished weapons. As a future Gunsmith, I will be able to not only provide protection, but also coloring on metalwork. When addressing the issue of a rusting weapon I, will start by removing the existing rust with either; steel wool or light grit sandpaper along with WD-40. After using the WD-40 and steel wool to wipe off the rusting…
