Bellows for Igniting Fire
Introduction: Bellows for Igniting Fire
Spring has come and the whole summer is ahead - which means a lot of country trips, meeting with friends, relaxing in the wild or camping. And, of course, this is an indescribable aromatic cuisine on the grill or on the fire. And nowhere in all this diversity can you get away from the fire!
In the wild, this is an opportunity to cook food and warm up, in a camping it is a cozy atmosphere and songs with a guitar around the fire (in Russia, an integral point for summer evenings). And you can't live without food at all: coals for grilling, tandoor ovens, Finnish candles for cooking food in a frying pan - all this requires fire!
Therefore, I would like to tell you about a device that greatly facilitates the campfire life. We are talking about bellows for kindling a fire.
The bellows are used to obtain a continuous air stream and are used mainly in blacksmithing and glass-blowing, as well as in some musical instruments (bagpipes, accordion). They have been known since ancient times, they were used in ancient Egypt.
The technical meaning of the device is that air is drawn into the inner space, and then leaves it in a continuous flow, which allows you to kindle a fire easily and without any difficulties. Regardless of the weather. Even in conditions of insufficiently dried firewood or coal. Easily and naturally make any fire in no time!
Let's get started :)

Step 1: Plywood Blank
Using a milling machine, we cut out all wooden parts from 9 mm plywood. You can use a material with a thickness of 10-12 mm, that will be great too. The structure will gain additional strength, but it is worth considering that the weight will increase slightly.
I do not recommend taking thinner plywood, in order to avoid additional difficulties in the assembly process. In addition, there is a great risk that thinner plywood will break during use, we tried 6 mm - it broke :(
Step 2: Grinding
It is very important to grind everything well. The better the material is processed, the more pleasant it is to work with it, and the smoother the paint and varnish fall on it.
For this I use a grinder and discs with a grid of 180, 320, 500 or 600 (here I do not pretend to be an expert, if you think that you need to grind with other discs, so feel free to do it, the main thing is a smooth result!)
It is not necessary to sand the edge strongly, since almost all edges will be covered with leather.
Step 3: Handle Preparation
We make approximately the same bevel on the handle pads.
This bevel is not difficult to do, but it is very important for the aesthetic appearance.
I do this at an angle on a sander using 80 grit discs and belts. After shaping, I create smoothness using the higher number discs from the previous point.
Step 4: Marking the Place Under the Nozzle
We mark the trapezoid of a larger size. as shown in the photos.
Step 5: Drill Approximate Nozzle Hole
In this step, we drill a hole with a drill bit much smaller than the nozzle, about 3-4 mm.
There are several reasons for this:
1. it is more convenient to drill with a thin drill, less chance of drilling through in the wrong place
2. can be drilled from both sides
3. the walls remain quite thick, the part does not become brittle
4. drilling a thin hole is easier than drilling a large diameter hole at once
Step 6: Gluing Wooden Bases
Read the instructions for your glue carefully! The quality of the connection of parts depends on this.
We only glue the handle strip to the short base.
To the base with a hole, on one side, glue the overlay on the handle, on the other side, first a large trapezoid, then a small one. Thus, a place is formed for the nozzle and fastening the bases to each other. We use clamps for high-quality gluing. 56
