Last Week Day 1

Before we started on the roof we had to straighten the walls and made sure there plumb.
Nick told us how to contruct and the safety aspects of scaffolding. It was quite easy you only need 3 people to put it up.
Whilst uga and william were cutting the rafters and chiselling them the rest of us were chiselling the bottom plate for the holding straps.

Last Week Day 2

Bracing requirementshow can we identify bracing elements from the plans
why did we fix bracing straps on the trimmer studs and the lintels.
how many nails did we use and what nails were they.

Roof framing
Name the two roof framing members that you placed on the roof today
At what centres were they.

Now had to make our own scaffold out of timber , it was quite easy coz there were already some parts made all we had to do was nail em together and plumb and square them.
Now that we can work on the top with the roof we measured and marked out the top plates of the back and front walls then put on the rafters and skew nailed em to the plates but not home so we can adjust if somethings wrong.
Then we marked the two end rafters and string lined em then cut the purlins and held em secure next to the string line and nailed.

Project Saw Stool

Making The Saw Stool




A saw stool is also called a saw horse. It has four legs, which can be made of timber or pressed metal. The head is made of timber.
A saw stool is normally used as a bench to hold timber, whilst it's being sawn.




Housing
- On the top mark out 150mm from each side and measure 70mm from there and mark out.
- Then with a marking gauge measure 20mm in from the edge then flip around and mark 2mm with the gauge.
- Clamp top on vice then to cut the sides of the housing joint use a tenon saw because it leaves a clean cut then use crosscut to cut the middle lines.
- Once the lines have been cut i used the chisel to cut the waste ( before cutting scribe the outside lines with the chisel blade so you dont cut over the line ) or end up with splits.
- Check to see if square with try square rule and make sure there are no gaps. check all for joints and then sand with a block of timber to keep an even surface.

Legs
- Marked each leg & joint 1,2,3,4 because all joints might have a different angle.
- Held the top bit against the housing joint and marked 2 points and ruled a line and matched those to the other side then cut with tenon saw.
- Once the line has been cut check to see if it can fit if not then plane off a little at a time and check keep doing this until it fits.

                What steps were there cutting legs to size
-Cleats

- Marked each cleat 1 and 2 and held it against the legs and marked out.

- Adding an extra 2mm to the marked line so we can plane off. Clamped it to the table and cut with tcross cut saw ( cutting on waste side )

-  Then hold against legs again and mark the sides for the position. Find the middle and mark a line down for the nail positions. Hold down firmly while drilling 3 holes on each side.

- Then apply glue and nail cleats to legs but dont hammer to hard jus enough for 3mm hanging out then nail punch them in.
- Once there nailed you can start planing on a angle do not go right to the end turn around and plane that direction.

                Tricks of planning
Braces

- Marked 50mm from one side then swap then on the other corner mark 50mm then match points together and you end up with a diagonal

- Put timber on vice and make sure the line looks plumb then cut halfway with crosscut saw and turn around and and cut other half.

- Put 2 pieces together flat on a table and hold together firmly and nail two.

- Once clamped together plane and check if square.

Week 5 Day 13

1st Block :
Worked on saw stool, marked out the top for housing joint using the sliding bevel and square.I used the tenon saw to cut the inside waste. The reason why i used the the tenon saw instead of the crosscut is because it leaves a much cleaner cut. Crosscut saw to do some cuts in the middle so itll be easier to cut with the chisel. I chiseled with a diagonal motion so it leaves a smoother surface. To check if housing is square then used the flat bit of the chisel and if you see a gap then its not square when finished one joint i did the same to the other three.
