Aerospace Supplier Shifts to Tight-Tolerance Ventilator Parts: "We Weren't in This Business Two Weeks Ago"

“We’re not doing this to make money, we’re doing this to save lives,” says Dodd Russell, CEO at Skilled Manufacturing Inc., a Tier 1 aerospace and automotive supplier located in Traverse City, Michigan.

Mr. Russell got the call from one of his major automotive customers on a Saturday morning asking if his company could help churn out 6061T aluminum parts destined for ventilators. Within an hour, he had 12 of his aerospace employees at the plant, ready to make it happen. After looking at the 2D blueprints of four parts, they went to work on the easiest one first, producing a prototype by Saturday night for submission. By Sunday, they had made a prototype of the second part, and by Monday, they had prototyped the third and fourth parts.

“At that point, I didn’t even have a purchase order. I told my customer that we would donate the parts if we were not chosen as a supplier. Luckily, our customer did choose us, but that’s not why we did it,” Mr. Russell says.

According to Mr. Russell, his entire supply chain has really “ponied up” to support them. For instance, the general manager of SMI’s aluminum supplier went in by himself Sunday morning to load the aluminum and deliver it to the plant. His tooling supplier sat in the parking lot calling suppliers Saturday night and was able to deliver tools by Sunday. There was a 72-hour turnaround time on all specials, Mr. Russell says.

“We weren’t in this business two weeks ago, but this is what Americans do when stuff like this goes on,” he says. “We didn’t plan on this. In fact, we just laid 150 people off in our automotive division the night before we got the call. Now, the 150 people in our aerospace division are working endlessly to support our main customers. This is our new reality.”

Mr. Russell commends job shops and certain other manufacturing facilities for wanting to do their part to make ventilator parts, but he can’t sugar-coat the reality that there is a certain baseline of tolerance requirements and cleanliness standards that must be achieved for some of these parts. SMI’s aerospace division is already perfectly set up to handle this new kind of work. The NADCAP certification, the clean room and the surface finishes that are standard for aerospace work made for a seamless transition for SMI to produce these medical parts. According to Mr. Russell, the ventilator parts are similar in surface finish and tolerance to the aerospace parts, which the company is accustomed to holding at 2 tenths. In some cases, the company even splits the tenths.

Even though his company went from running a 4/10 work schedule to seven days straight with two shifts running 10 hours each, Mr. Russell says his company is not at capacity. In fact, at the time of this writing, he had been approached by another organization and was in preliminary conversations about making parts for a different type of ventilator.

In the midst of this, SMI is also working to keep its employees safe. The plant is completely locked down — no outside visitors or suppliers can enter. Mr. Russell says they are following full CDC protocols using face masks, social distancing and thermal scanning. “It’s a Herculean effort for our employees just to get into the plant,” he says. He also has backups in place. “We have a plan for every person and every machine. There is no single-point failure.” These backup plans were already in place before the pandemic hit, as they are considered normal contingencies for aerospace work.

At the end of the day, Mr. Russell and the employees at SMI are just trying to do their part. “We live in a small town. We’ve known each other for a long time, and we all take a lot of pride in our work and workplace. This ventilator work is a testament for my employees. They want to stand up and be counted. We’re all just small-town folks who are working hard to save the lives of those in our town and our friends.”
