Saws

 

1. Product Description: Saws are made from high carbon steel having teeth on the edge of one side.  They are essentially of two types- circular and linear.  Saws are one of those hand tools which are used in all types of activities where cutting of wood and wood products is involved.

 

2. Rationale: The wood cutting works going in the whole Amhara Region require the use of saws.  However since saws are not available in sufficient quantity, wood cutting is done using axes.  Unless for splitting logs, axes are not very convenient and efficient for cutting wood.  Besides, there are many types of wood cutting works (joineries, timber production carpentry, etc) which exclusively require the use of saws.  All types of saws used in the Region and for that matter in the country are imported.  But except the manufacturing of high carbon steels sheets from which saws are made, the production of saws is a simple workshop operation which can be done anywhere in our country.  The Amhara Region should promote this project so that the country could start fabricating saws which work manually.

 

3. Market potential: To prove the existence of a sufficient market for saws in the Amhara Region, one does not need to quote import or consumption figures.  These figures are quoted when the gap between domestic production and consumption are close which entails the possibility of risk because of market saturation.  In a situation where domestic production is non-existent and consumption is satisfied by imports, one can safely conclude that there is sufficient market for the production.  this is the situation for hand saws.  There is a demand for them which can absorb the production of a small production unit.

 

4.  Source of Raw Material: Saws are made from high carbon steel sheets.  These sheets will be imported.

 

5.  Process & Technology: The high carbon sheet is cut into square pieces, then corners are pruned on the sheet cutter.  Then these pieces are drilled and bored on the lathe further these are put on mandrel and turned to accurate size.  Then the teeth are cut on the milling machine.  The pieces are then heat treated.  Bore is internally ground while both the faces are surface ground.  Main machines required are lathe, sheet cutter, milling machine, special purpose tool, stamping machine, bench grinder and workshop tools.

 

6.  Estimated Investment: For a plant which will produce about 800 saws per month, the estimated investment will be:

 

§        Building -150 m2 at Birr 1500/m2 =Birr 225,000

§        Machinery                                       =Birr 125,000

§        Working Capital                              =Birr  50,000

                                          Total                          = Birr 400,000

 

7.  Benefits: self-sufficiency, saving foreign exchange and regional financial resources, introduction of new skills and technology, possibility too export to other parts of the country.

 

8.  Location: Bahir Dar, Combolcha.
