Certainly a valid option, but if you get one over-zealous person (think finals match 5-minute repairs) who spins or strips a pressed-in nut you could find yourself totally hosed. If the nut is riveted in then the rivets can be drilled out and a new nut riveted in very quickly. I work with an ex-A&P mechanic and we've used these nuts with great success.

#8-32 and #10-32 PEM nuts both use a .25 or smaller hole that they are pressed into. If there is ever an issue where they get stripped/pushed out, they can be replaced with a 1/4-20 bolt and nut. We've been using them for two years now on critical drive train/chassis sheet metal components, and as far as I know have yet to have one strip or fail.

Instead of using a master link, the DarkSoul chain break is used is used to drive the pins [partially] out of the roller chain, put two ends of the chain together, and then drive the pin back in. There is no master link because any link can be the 'master link'.

It's too bad about the out of stock issues; the one we picked up back in December has proven to be one of our most useful tools. If the DarkSoul chain breaks are no longer in production, it's not a very difficult device to reverse engineer and machine yourself on a milling machine.

I realize Aircraft Spruce isn't the cheapest place to buy things, but it's the first source that came to mind.

Ack! Don't buy things from Aircraft Spruce, they have awful customer service, and habit of messing up orders. A good friend responsible for maintenance on 30 antique airplanes has had them screw up more than one large (>1k) order. On the other hand, he's never had a problem with Wicks.

I'm not entirely certain. But I have a feeling businesses don't care what peoples jobs are when their orders get messed up. ;)

An A&P mechanic (Airframe and Powerplant) is an aircraft mechanic, I was merely implying that he ordered from Aircraft Spruce frequently.

Its a shame that we can't get more of these breakers........We are currently working on a replacement. I'll keep the forum updated when we have them back in stock.

Re: pic: WCD Sheet Metal Concept Chassis

I've used a regular chain breaker to push the pins back through, then taken a hammer and peened the pins back over using a bench vise as an anvil. It is low-tech and requires a little practice to keep from binding up the chain, but it works.
