So we've had a few customers a little bit intimated by the tapping process of the Super Sport Evolution. I assure you that tapping is really easy and a skill you can feel proud of once you've got the hang of it.  Tapping aluminium is a very simple process, and is one of the first tasks and engineering apprentice will learn. It's best to buy a set of 3 taps, because the cost difference between one VS three is similar when purchased as a set. They are available typically at all engineering stores, eBay, lowes hardware and Home Depot... Taps are known...

Custom hardware is often not more expensive and often looks better. 8020.com has such a high mark up on joining plates, it makes OpenSimRigs custom plates very competitively priced even though we are making very small quantities at the moment. For example lets look at two ways to design a complex wheel assembly cross brace The first example below shows 6 standard pivot joints costing $124.50 in 15 series, from 8020.net.
