Saw horse


Here are some photos of my sawhorse that I made in term 1 (2021) for Wood technology, (BCATS) L1 NCEA. 

This took me nearly the whole term which was 10 weeks long. so a bit shorter than 10 weeks, (maybe 7 or 8)

In this blog, I will show you evidence of me making the sawhorse and the set of instructions that tells you how to make it. I'll also tell you about the hand tools we used and how we used them.

What I enjoyed the most about creating my sawhorse was that if we made a mistake we got a second chance, we just didn't make that same mistake twice. What I also liked was that we got a practice assessment so we could fail and it wouldn't matter and so we wouldn't fail on the main assessment/sawhorse.

           Heres my 3 photos.


Sliding bevel: For this handtools assessment we set all of our sliding bevels to a 15-degree angle. We did this because every angle we needed to mark out was either 15-degrees, 180-degrees (straight), or 90-degrees. Basically, any angle that wasn't 15-degrees was 180-degrees  or 90-degrees




Combination square: We used a combination square to mark any straight lines that were square with our piece of wood (90-degrees). This tool was a lifesaver. It's used instead of a ruler to get a straight line because we set the revolving turret piece to 180-degrees to get it nice and square.




Handsaw: We used a saw just as a saw is made for, cutting wood, however, our teacher Mr. Rees Showed us how to use a saw properly. Keep your elbow close to your body and follow through the piece of wood with your arm going straight the whole time to keep the cuts straight and prevent the blade from wobbling. Use all the teeth of the saw and take your time rather than going way too fast.





1 Metre ruler: At the end of our work we had to straighten/even up the legs of our sawhorse. how we did this was by putting the sawhorse upside down on a table. Then finding the shortest leg. let's say the shortest leg was 780mm tall we'd mark a line on all four legs at about 775mm and then get our ruler and join up both marks on the outside of our 2 legs and mark a straight line. We did this on all sides of our four legs.



Below is some photo evidence of me doing the work.

this is me hand sawing the end of one of my legs at                                      a 15-degree angle.

 This is me marking out the top of my work and                                                                            planning my legs with a sliding bevel.

This is me attaching the support to the base of my                                                                                              work. It is also attached to both of my end pieces,                                                       we screwed it on afterwards


here's a photo of some of the hand tools we used to create our sawhorse.     






           
This is the sawhorse we need to construct. The whole set of                                  instructions are below in the pictures.











This is the end of my blog post (: Please comment to let me know how I did.
