arnoldc,
di ko alam yung exact address, per naroon lang yon sa vicinity ng aranque, you can buy your aluminum from sulimco cut to size, give some allowance, cause crude ang cutting methods nila, then there are nearby shops doing bending, there is one shop owned by " pio" a chinoy, then there's another one accros the steet from aranque, this one has a box bender.............last time i went there was in 1994, before i went overseas as an ofw....as to heasinks, we are only limited to what's available at either deeco or alexan, invensting in an extrusion die costs around 50thou...and another 50 thou for a minimum order so it is a costly proposition, wish i had that money.....
