I've already had my bushing installation set-up copied by someone who was supposed to be a good "friend". He also copied several other items that were proprietary to my business, and started selling them from his website. From that point on I do NOT share any specific information about anything that we have made here.
All of our springs are custom wound, fasteners custom made, and we use ethanol compatible pump seals on our accl pumps, not the "soft" blue crap you get in over the counter kits.
The drill bits in question here are very expensive to purchase, and expensive to have ground. It takes a special process to grind them down and make them suitable for boring into the soft aluminum without binding up. Finding someone to do this will not be easy, or inexpensive......FWIW.....Cliff
