NTL Industries founder and proprietor Greg McArthur thinks in aim-centered arranging. “One of my favorite strategies was from Elon Musk. He stated to have a 10-12 months program but consider to accomplish it in six months. You’re hardly ever heading to complete it, but you will be a whole lot more ahead than if you weren’t trying to carry out that even larger 10-12 months program.” All photos courtesy of NTL Industries.
Greg McArthur grew up in the family members machine shop, happily accomplishing the grunt operate although he was still in substantial faculty — from cleaning to driving to expending Saturday nights painting pieces. He figured out from his father and uncle on the career, as nicely as by way of courses at a nearby neighborhood college or university. He parlayed this information and encounter into turning out to be a device operator and comprehensive-time personnel. Points have been likely properly, but like so a lot of other device outlets in the region, this just one suffered from the fallout of the Great Economic downturn in the late 2000s and closed. But that was not going to be the stop of McArthur’s vocation as a machinist or in a family members business enterprise.
He uncovered do the job with a hydraulics manufacturer, but dreamed of opening a production organization of his personal. He and his spouse Shelley came up with a enterprise identify in excess of evening meal a person night: NTL Industries. The acronym stands for “Never Far too Late” or “Nothing To Lose.” He states both operate for the enterprise they launched in 2017.
Currently that business has 11 staff and has a short while ago added abilities together with horizontal machining. Substantially, the aspiration has also expanded. McArthur is preparing to become a manufacturer of aftermarket automotive components — and the horizontal machining middle will permit this. Below is how automated machining, precisely jogging lights out, can allow a single store to operate as a occupation shop by day and a manufacturing company by night time.

Making With Progress in Mind
McArthur commenced NTL by acquiring a Bridgeport knee mill and a CNC lathe to established up store in his 500-square foot household garage when nevertheless performing complete time. The CNC lathe was a particularly considerable financial commitment, but he understood he necessary the lathe to be programmable so he could run it and the mill at the same time.
He continued to work complete-time and would spend various hrs each individual afternoon doing profits for his individual business enterprise. “If anyone experienced a ‘help wanted’ indication, I’d cease in mainly because of course they experienced extra do the job than they could handle,” he suggests. “I’d leverage individuals chances to get them by way of whichever they necessary,” making interactions and rely on between these other shops. This helped McArthur improve the business enterprise, and generate long lasting associations with other nearby shops, lots of of whom are even now shoppers now.
In just 6 months, McArthur resigned from his occupation and dedicated to NTL Industries full-time. He outgrew the garage and leased his initially making in March 2019. By the finish of 2020, when the US was in the entire throes of the COVID-19 pandemic, NTL had 8 complete-time workers had included a few Haas CNC vertical machining facilities, a CNC plasma cutter and a welding section and had expanded to 3,500 square ft. NTL Industries also acquired its ISO-9001 certification at this time.

Resourceful and Strategic Expansion
McArthur had usually prepared for the enterprise to be far more than a occupation store — he required the ability to know some of his very own item tips as very well, in outcome getting an OEM. This aim served condition the trajectory of his business’ expansion. He bought most of the machines secondhand from eBay and Facebook Market. But he realized he had to grow not only his tools, which he did however shopping for machines secondhand from eBay and Facebook Market, but also his abilities. So, he ordered two Doosan (now DN Methods) machining centers in 2021, each of them new, a person of which was the shop’s to start with horizontal machining center.
It was important to McArthur to acquire the two equipment from the similar builder. “I knew I was heading to buy two machines, so generating absolutely sure the controls ended up pretty identical was important to not obtaining to discover two various systems,” he claims. It was also crucial that the devices have massive enough tables and perform envelopes for significant sections and manufacturing operates. Right now, he and the group operate to establish how to finest set up components and sequential operations on the devices to increase spindle time. They also make several of their individual workholding units, built for economical set up and/or fast changeover.
He regarded as getting a five-axis equipment, realizing it would mature NTL’s capabilities even additional, but the shop could not yet justify the cost. “We’re undertaking five-sided machining on our horizontal Doosan by spinning the portion and remachining the other facet,” he claims. “I would really like to get into it with a genuine five-axis machine, and I will. It’s not a issue of if, but when.”
Castings also account for a considerable share of the job shop get the job done. The aspect on the right is a forged drinking water pump housing received from a purchaser, when the part on the still left is NTL Industries’ choose as machined on the DN Options NHP5000.
Operating Towards Comprehensive Lights-Out Output
The DN Answers horizontal is a NHP5000 machine. It has a 19.7” pallet, with a maximum workpiece measurement of 31.5” by 39.3”. The variation NTL purchased has a 60-instrument potential and Renishaw probes for instrument and workpiece measurement.
The companion vertical is a DN Options DNM5700S machining centre with a 51.2” by 22.4” desk and 2200-lb. capacity. The addition of these two machines is by now altering the trajectory of the company’s growth. By having full advantage of the machines’ capabilities, NTL can do even larger pieces in stacks of six or eight pieces superior and equipment all the faces of a portion in just a couple of operations. The NHP5000 has a two-pallet program so the operator can established up for the subsequent career and have it prepared to load when an operation is completed functioning, minimizing hold out time concerning jobs.
Brian Kozlowski is the operator of the HMC. With 24 years machining practical experience, he came to NTL right after doing the job with McArthur at his former employer. Kozlowski began his occupation undertaking on-equipment programing but now is effective in Mastercam to program the DN Remedies equipment.
This prototype portion was machined on the HMC in equally 7075 aluminum and 4140 steel. Machining was carried out 360 levels about the section applying the HMC’s fourth axis.
Existing Job Work
Today, NTL Industries focuses on a couple of vertical markets — agriculture and defense. The firm manufactures a wide variety of turned items, along with from time to time elaborate components milled on its machining centers. Dependent on the work, NTL may start out from metal or aluminum billet or from castings.
One spot of advancement is workholding tooling for other retailers. “We can fill the voids when we have compact downturns or holes in our working day-to-day generation and enable out fellas like me when I very first started off out,” McArthur claims. “We can assistance them preserve their expenditures down,” leveraging some of what NTL has figured out about fixture tooling all through its very own get the job done. This is the beginning of the enterprise sourcing its very own merchandise, and the aim is to go to lights-out manufacturing, notably on the new HMC.
“We need to make sure the timing is right. We really don’t want to operate our devices for 8 several hours at 50%, slowing them down. The intention is to allow them run at capacity overnight,” McArthur claims. “We want it to be as economical as doable so we can gang components and operate consecutive functions.”

A New Organization Inside the Enterprise
In addition to the task shop perform, NTL has introduced an offshoot brand: NTL Motorsports. McArthur got the notion from looking at his son, who is a go-kart racer, and now helps make a line of aftermarket pieces for go-karts.
“We’re beginning with oil capture cans, but from there we’ll preserve incorporating to the merchandise line,” McArthur claims. He ideas for the shop to gradually progress into this line of products, planning new offerings then shifting them into output as unattended potential warrants.
“With the Doosans, we’ve bought automation functionality, and that will open up additional doorways for us,” he says. Recurring production of his very own products can operate at night, although less-predictable occupation shop machining can even now fill the working day, when there are workforce customers onsite to oversee the get the job done.
Also coming from the NTL Motorsports line: elements for genuine vehicles. The initial of these was a bumper for the Jeep product McArthur drives, with operations and welding executed in-house.

McArthur has already refined the style and design for the future round of this solution. The DN Alternatives equipment will permit NTL make several parts for the bumpers at the same time with one established up. “We’ll be in a position to stack parts and slash all the holes and mounting openings at after due to the fact they will be copy parts. We’ll load the equipment and enable it operate all evening. The ultimate products will be superior than what we could do now since we’ll make one particular integral frame piece in the Doosan for the bumper and all the extras — the lights, winch, and so forth. Then you won’t have as a lot of distinct components building up the bumper, so there is fewer place for it to split.”
A line of customized rims is also in growth, beginning with protecting rims for McArthur’s have Jeep. “We’ll make regular blanks that people today can personalize and design to say what ever they want it to say. We’ll device the rims on the Doosans and customise with the plasma cutter. Regardless of what own contact you want to put on it, we’ll try out to make them fully customizable for our clients.” With ideas like these to go after, and with a flourishing manufacturing business enterprise furnishing a platform to go after them, the future seems to be vibrant — and fairly ironically, it appears all the brighter many thanks to lights-out manufacturing.
