A long-due explanation for the Five Years of Silence

15 June, 2017

First "real" update in five years! It's about time... But before any actual oil-hydrauics posting can happen, I have to do some serious "remodelling" around here, i.e. replace the outdated static design with something more adaptive and mobile-friendly, which is a gargantuan task, given the fact that I did everything wrong when I created the blog with a free visual editor and zero knowledge of HTML. But it needs to be done, and it will be done. I'm starting with the home page, and will eventually "grind" through the rest of the site. Should anyone catch any "funny looking business" in the browser, please, shoot me an email describing it - I'll do my best to correct the errors. Also - older browsers might not display the new code correctly.

The reason why I've been offline for all this time is simple - we are expanding our business to the Sothern part of Portugal,and I have but two months to set up a functional warehouse and a workshop - way too little time if you ask me, so I've been working 24/7, and yes - no vacation for me this year... Still managed to add three more links to the article on Aftermarket Spares: A6VM Pistons, Seal Kits, and NG10 Valves
