NTL Industries founder and proprietor Greg McArthur believes in goal-targeted scheduling. “One of my preferred thoughts was from Elon Musk. He mentioned to have a 10-12 months prepare but check out to accomplish it in six months. You’re in no way likely to accomplish it, but you will be a ton additional forward than if you weren’t seeking to accomplish that more substantial 10-12 months plan.” All pictures courtesy of NTL Industries.
Greg McArthur grew up in the relatives device shop, happily performing the grunt perform whilst he was nonetheless in significant university — from cleansing to driving to shelling out Saturday evenings portray pieces. He figured out from his dad and uncle on the job, as properly as by way of classes at a nearby neighborhood school. He parlayed this knowledge and experience into turning into a device operator and whole-time staff. Factors were being going very well, but like so lots of other equipment retailers in the region, this just one experienced from the fallout of the Good Recession in the late 2000s and closed. But that was not likely to be the finish of McArthur’s career as a machinist or in a household enterprise.
He found function with a hydraulics company, but dreamed of opening a manufacturing enterprise of his possess. He and his spouse Shelley came up with a organization identify above evening meal one evening: NTL Industries. The acronym stands for “Never Much too Late” or “Nothing To Eliminate.” He suggests the two work for the business enterprise they introduced in 2017.
Right now that business enterprise has 11 staff and has just lately added abilities which includes horizontal machining. Substantially, the desire has also expanded. McArthur is preparing to turn out to be a producer of aftermarket automotive parts — and the horizontal machining heart will help this. Here is how automatic machining, particularly working lights out, can let a one shop to run as a career shop by working day and a manufacturing maker by evening.

Setting up With Progress in Brain
McArthur started out NTL by acquiring a Bridgeport knee mill and a CNC lathe to established up store in his 500-sq. foot dwelling garage when still operating whole time. The CNC lathe was a notably important expense, but he realized he needed the lathe to be programmable so he could run it and the mill at the exact same time.
He ongoing to function whole-time and would commit several several hours each and every afternoon executing income for his possess enterprise. “If anybody had a ‘help wanted’ indication, I’d halt in because clearly they experienced far more perform than they could deal with,” he suggests. “I’d leverage people opportunities to get them as a result of no matter what they wanted,” setting up interactions and have confidence in between these other shops. This assisted McArthur improve the small business, and generate lasting relationships with other neighborhood retailers, a lot of of whom are however shoppers nowadays.
Inside six months, McArthur resigned from his work and dedicated to NTL Industries complete-time. He outgrew the garage and leased his 1st developing in March 2019. By the conclusion of 2020, when the US was in the entire throes of the COVID-19 pandemic, NTL had 8 comprehensive-time personnel experienced added a few Haas CNC vertical machining centers, a CNC plasma cutter and a welding department and had expanded to 3,500 sq. ft. NTL Industries also acquired its ISO-9001 certification at this time.

Innovative and Strategic Growth
McArthur experienced always prepared for the organization to be a lot more than a position store — he desired the capacity to realize some of his own products ideas as well, in result becoming an OEM. This purpose assisted shape the trajectory of his business’ progress. He purchased most of the machines secondhand from eBay and Facebook Marketplace. But he understood he experienced to expand not only his tools, which he did however getting equipment secondhand from eBay and Facebook Marketplace, but also his abilities. As a result, he purchased two Doosan (now DN Options) machining centers in 2021, equally of them new, one of which was the shop’s initially horizontal machining heart.
It was essential to McArthur to buy the two devices from the exact builder. “I understood I was going to get two devices, so making positive the controls were being pretty comparable was crucial to not getting to understand two unique systems,” he says. It was also important that the equipment have massive adequate tables and function envelopes for huge parts and creation operates. Today, he and the crew perform to decide how to ideal established up pieces and sequential operations on the machines to maximize spindle time. They also produce numerous of their own workholding techniques, created for inexpensive setup and/or fast changeover.
He regarded as paying for a five-axis equipment, realizing it would expand NTL’s capabilities even much more, but the shop could not however justify the charge. “We’re accomplishing 5-sided machining on our horizontal Doosan by spinning the aspect and remachining the other side,” he says. “I would like to get into it with a true five-axis equipment, and I will. It’s not a subject of if, but when.”
Castings also account for a major share of the occupation shop get the job done. The component on the ideal is a solid drinking water pump housing gained from a shopper, when the portion on the left is NTL Industries’ just take as machined on the DN Options NHP5000.
Working Toward Entire Lights-Out Output
The DN Answers horizontal is a NHP5000 device. It has a 19.7” pallet, with a optimum workpiece size of 31.5” by 39.3”. The version NTL obtained has a 60-resource capacity and Renishaw probes for tool and workpiece measurement.
The companion vertical is a DN Options DNM5700S machining center with a 51.2” by 22.4” desk and 2200-lb. capacity. The addition of these two devices is already switching the trajectory of the company’s expansion. By using complete edge of the machines’ abilities, NTL can do even larger components in stacks of six or eight components significant and equipment all the faces of a element in just a pair of functions. The NHP5000 has a two-pallet process so the operator can set up for the future career and have it ready to load when an operation is accomplished operating, minimizing wait time among jobs.
Brian Kozlowski is the operator of the HMC. With 24 years machining working experience, he arrived to NTL immediately after operating with McArthur at his earlier employer. Kozlowski started his career carrying out on-device programing but now performs in Mastercam to method the DN Methods devices.
This prototype aspect was machined on the HMC in both equally 7075 aluminum and 4140 steel. Machining was performed 360 levels close to the component making use of the HMC’s fourth axis.
Present-day Challenge Do the job
Now, NTL Industries focuses on a couple of vertical markets — agriculture and protection. The organization manufactures a variety of turned merchandise, together with in some cases intricate pieces milled on its machining centers. Based on the job, NTL may perhaps start out from steel or aluminum billet or from castings.
One particular space of advancement is workholding tooling for other stores. “We can fill the voids when we have tiny downturns or holes in our day-to-working day generation and enable out men like me when I initially started off out,” McArthur suggests. “We can support them hold their fees down,” leveraging some of what NTL has discovered about fixture tooling during its have do the job. This is the beginning of the corporation sourcing its own product or service, and the target is to go to lights-out manufacturing, specifically on the new HMC.
“We need to make positive the timing is appropriate. We don’t want to run our equipment for 8 hours at 50%, slowing them down. The goal is to enable them operate at capacity overnight,” McArthur suggests. “We want it to be as efficient as probable so we can gang sections and operate consecutive operations.”

A New Enterprise Inside of the Business
In addition to the job store get the job done, NTL has launched an offshoot model: NTL Motorsports. McArthur acquired the concept from looking at his son, who is a go-kart racer, and now will make a line of aftermarket elements for go-karts.
“We’re starting with oil catch cans, but from there we’ll hold including to the products line,” McArthur says. He options for the shop to little by little progress into this line of merchandise, designing new choices then relocating them into manufacturing as unattended capability warrants.
“With the Doosans, we have got automation capability, and that will open far more doorways for us,” he states. Recurring generation of his individual goods can run at night, while much less-predictable task store machining can however fill the working day, when there are team associates onsite to oversee the operate.
Also coming from the NTL Motorsports line: pieces for actual automobiles. The first of these was a bumper for the Jeep product McArthur drives, with functions and welding carried out in-house.

McArthur has already refined the design for the following spherical of this product. The DN Alternatives devices will allow NTL make various elements for the bumpers concurrently with one set up. “We’ll be capable to stack sections and slash all the holes and mounting openings at as soon as simply because they will be copy sections. We’ll load the device and let it run all evening. The final item will be much better than what we could do now because we’ll make just one integral body piece in the Doosan for the bumper and all the equipment — the lights, winch, etcetera. Then you won’t have as numerous distinct parts building up the bumper, so there’s less place for it to break.”
A line of custom rims is also in development, beginning with protecting rims for McArthur’s individual Jeep. “We’ll develop standard blanks that people can personalize and style and design to say no matter what they want it to say. We’ll machine the rims on the Doosans and customize with the plasma cutter. Regardless of what private contact you want to place on it, we’ll test to make them absolutely customizable for our buyers.” With tips like these to pursue, and with a flourishing manufacturing company giving a platform to go after them, the potential appears to be shiny — and to some degree ironically, it appears all the brighter thanks to lights-out creation.
