Rooftop mini tower project

I am embarking a new mini project which hopefully can be materialised within at least a month time. It has been almost a year and my 10 element VHF yagi has been in the storage collection dust and my newly bought 3 element 10m yagi will surely does not see the light if I don't start this mini project. 

(just an illustration - one of the GlenMartin tower)

The design of this mini tower should look like a copy of the commercially available (at least in the US) from GlenMartin RT424. It will be at least a 4.5' high, aluminium made mini tower which hopefully could last quite a long time and withstand a strong wind. 

What I've done so far:

1. Bought 40' aluminium angle cut into 5' from Alumimac (not far from my new base). Cost me MYR 49 per 20'.

2. Have at least a rough drawing of the final product.

Thing I need to do now:

1. Finalise the drawing with all the dimensions calculated correctly.

2. Spend my time to cut .. cut .. and cut .. I don't have those electrical metal cutter or saw, so my guess using a small manual metal saw should work just fine.. hopefully...

I will update this blog with any photos taken during this mini-project. Wish me luck!

UPDATE: Read this!!! And be careful when working on tower .. http://tech.yahoo.com/blogs/null/97827
