I always wanted to have a technique bar, don't know why exactly but thought it would be good to have a light bar, regulation size with very light training plates for the correct distance to the ground. A couple of month I ago I made one, for free.
That's the commercial variant, cost in Germany around 300 EUR...

That's mine, regulation size sleeves of course non revolving, made from 25 mm diameter alluminum tube (wall 3.5mm EDIT: measured it today again) which I got for free. The alluminium is secured by screws in the wooden sleeves and I have clean & jerked with this bar over 50kg without a problem. Weight is around 1.6kg and loaded with two 2.5kg plates it has a comparable whip to an olympic bar.
