Obsession Engineering (Rapid) is an excellent channel and Dave is a smashing bloke. Worth putting in your favourites list.
Yes I like his content, mate of mine who watches his channel let him try and quote for commercial engineering work but the order was too large for him.
Memories of flaking rockers and big-end bearings on the limit with 748's brings me out in a cold sweat. Aaaarggghhhh. Happy days; more Km on a flat bed truck than riding!
