How To Cope A Joint

A coping saw is a carpentry tool that is mostly used by carpenters who finish ceilings, floors and other areas that require a neat look. It is quite basic and consists of a wooden handle and a U shaped metal throat. Joining the two ends is the blade that is used for the actual cutting of the material in question.

The tool got its current name from the type of cut that it is predominantly used for, coping a joint. So what is coping?

Coping is the process of cutting and joining two irregular patterns to fit each other neatly. In other words it involves joining two irregularly shaped molds, usually in the corner of a room with something like a skirting board.

How do you cope using a coping saw? Let’s take a deeper look:

1. The first thing to do is to take the two moldings that are to be cut and make a mark along where the coping saw will cut. It is very important to do this as it will give you a line to follow so you can make an accurate cut. A little hint here is to make the cut at a 45 degree angle.
2. The next thing to do is to cut along the drawn lines on the first molding that you want to join. To make sure that you will not cut into an unwanted region, position your coping saw just below the cutting line. This is very important. Cut through to the very end.
3. Now the next thing is to cut the second piece of molding. To do this correctly, position the molding that you’ve already cut against the molding that you want to cut. Mark a line with a dark pencil along where the edge of the already cut molding corresponds with the molding to be cut.
4. Now repeat the cutting process once again. Just as you did with the first molding don’t position your coping saw blade at the line, that would be a mistake; position your blade a few millimeters away from the cutting line. For this one, you can cut without needing to be at a 45 degree angle.
5. After you’ve done the cutting of both of the moldings, fit them to see how well they  fit. The next thing to do is to adjust the fit with a knife, file and sandpaper. Chances are high that you won’t have gotten the cut perfect on the first attempt. Take a sharp blade, smoothen one of the moldings in a regular manner and be careful not to dig too far as this will result in you having to start over again. Keep refitting the two molds frequently and keep removing the excess material. As you get closer to a good fit switch to the file and finally over to the sandpaper.
6. Lastly attach the molds to the wall (or wherever you’re placing them). If you’ve done well then you’ll need to do nothing further, but don’t be too upset if you need to add a little filler; the perfect cope takes many attempts to master.

Jigsaw - The Ultimate Cutting Machine

A jigsaw is a mechanical power tool which is usually used to cut things into pieces. It is made up of an electric motor and a reciprocating saw blade. This kind of saw is also called by some manufacturers, as a “Bayonet Saw” or “Sabre Saw”.

Every one of us, have always used a tool, but have we ever thought what the story behind this tool is? Have anyone ever thought who made this tool and why he made it? Have we ever thought how it works? I guess none of us did that. Let’s learn something about the saw history and its types and working principles.
In the year 1946, an engineer named Albert Kaufmann, who was working in Scintilla AG Company, Solothurn, Switzerland, replaced his wife’s sewing machine’s needle with a saw blade. The following year, in 1947, using Albert Kaufmann’s invention, his company Scintilla first started producing this power tool calling it the“Lesto Jigsaw”. Later the company was acquired by Bosch, and the name Lesto was replaced by Bosch. In 1966, they added pendulum action to the movement of the blade.

Over time, additional features have been added and different power options. There are mainly 4 kinds of saws:


•    Corded Jigsaw
This kind of modern tool has electric wire connection. This is a sophisticated curving machine with modern and very fine features to fulfill all kinds of cuts in the all kinds of material. The most powerful corded jigsaws can cut wood up to 2 or 3 inch thick. It can cut deep Aluminum and even in steel.

•    Cordless Jigsaw
A tool without a cord. This type had a battery instead of a cord. Charge up the battery and use the blade to cut off any kind of shapes in wood and other materials. Though cordless tools need charging and are typically less powerful than corded tools, they have the advantage that they can be used in cases where an electric socket is not available.


•    Pneumatic Jigsaw
Pneumatic saws are a new idea in the field of this power tool. This is a new addition in the history of jigsaw. Previously air tools were quite common among movable sanders, but now, it is also a concept for jigsaws. A pneumatic jigsaw is connected to a decent sized compressor. It is as powerful (or maybe more) as the corded ones. Lack of electricity makes it a lot safer to work in wet or damp places.


•    Bayonet Jigsaw
Bayonet jigsaw is a bit different than all others stated in above. It was first developed in the 1950s by Porter-Cable. This type of tool uses a worm gear to transfer the power to the blade-reciprocating mechanism. It is used to cut thinner woods, metals, plastics, laminates etc.


Let's talk about blades. Is there a single kind of blade which fits all saws? Or there is different kinds of blades serving different purposes? What do you think? Let’s see.


There is a wide range of blades which also shows the wide range of uses for this too. The types include:
•    Various number of TPI (Teeth Per Inch)
•    Blade edge for cutting soft materials
•    Cranked blades to overcome the set back of the blade and allow flush cutting
•    Thin Blades to cut tighter curves.
•    Push stroke cutting blades to avoid damage to the top surface.


This is not an extensive list, there are lot of types of blades out there, but this shows the main types which are commonly used.
