Within Tolerance Episode 284 - The Sea of Kern - IMTS 2026 Sep 26, 2026

Show notes

Everyone's answer for the best part of IMTS 2026 was the same: the people. Zap, Justin, John Grimsmo, Chris Hopkins, Andrew Henry, and James Meyette join me across four days of mini episodes, recorded from the Kennametal, Rego-Fix, Datron, and Matsuura booths, to talk about what caught their eye. We get into less AI hype than expected, metrology finds in the back rows, high-density workholding done the crawl-walk-run way, and the unglamorous side of running automation overnight. We also talk about a very special knife reveal and a packed meetup, with a massive thanks to Kern for hosting!Check out Zap's IG @zap.consultingCheck out Justin's IG @justingraylabsCheck out Andrew's IG @henryholsters

Within Tolerance Episode 283 - 5 Years of Change With Andrew Henry Sep 05, 2026

Show notes

Andrew Henry of Henry Holsters is back after nearly five years, and a lot has changed: 11 employees to just over 30, a building addition, a Matsuura MX-420, and a shift from making parts to running the whole stack for other holster brands. We get into hiring his first real programmer and handing over the keys, the dark side of lean and why gratitude has to come with it, bringing on a fractional CFO, and why you should set up a line of credit before you need one. Plus the one-button shipping software they built that pushed 1,100 orders in a single day.Shipster Pro: https://shipsterpro.com

Within Tolerance Episode 282 - The Bot Will Remember This with Zap Aug 28, 2026

Show notes

Zap and I go live one more time before IMTS with Patreon members firing off questions. We map out the meetups (Kern on Wednesday the 3rd, plus a rotation of podcast recordings around the show floor) and swap updates: Zap on Kinematic Sauce, CritLink, and nonstop coast-to-coast travel, me on the new auto CMM, the coolant dosing project, and the podcast bot that's now live in the Discord. Plus a Fraisa vs. the world taper battle in 17-4.Check out Zap's IG @zap.consulting-----------------------------------------Help support the podcast www.patreon.com/withintolerancepodcast

Down the Rabbit Hole with Justin Gray EP4 - Standard Tools Are the Cheapest Automation You Can Buy Aug 11, 2026

Show notes

Justin and Zap are back for chapter four of My Tool Library Is Better Than Yours: Standard Tools Are the Cheapest Automation You Can Buy. Standardizing saves you a little time every day, but the real money is in killing the expensive outliers that blow up a Saturday night. They get into what "standard" actually means (it's not one holder for everything), why drills and taps are the best place to start, buying a holder or at least a collet with every tool, and keeping a bullpen of ER holders for the one-off cutters. Plus the pull-stud fix Justin talks himself into live on the mic.Justin's IG @justingraylabsZap's IG @zap.consulting-----------------------------------------Help support the podcast at www.patreon.com/withintolerancepodcast

Within Tolerance Episode 281 - Eddie Riddell of Steele & Co Engineering Aug 04, 2026

Show notes

Eddie Riddell of Steele & Co Engineering joins Dylan this week from his one-man job shop in one of the most remote cities in the world. Eddie traces a wild path from a New Zealand apprenticeship to the Australian mines to going out on his own, buying Haas machines sight unseen from across the world and landing on a DN Solutions SMX mill turn. They get into learning G-code out of necessity, why turning tools in Fusion are a nightmare, and the fixtures that have no business working but do. Plus the payment dispute he settled with an angle grinder.Eddie's YouTube for his boat, container house, and other builds: https://www.youtube.com/@eddiereddierEddie's IG @steele_co_engineering-----------------------------------------Help support the podcast www.patreon.com/withintolerancepodcast

Within Tolerance Episode 280 - Long Lists and Kinematic Sauce Jul 24, 2026

Show notes

A long overdue catch-up with Dylan and Zap. Dylan owns up to overcommitting the shop and relearning that automation doesn't save you from yourself, then runs through tooling, RO water, and a 3D printer that ate itself mid-print. Zap talks Kinematic Sauce, building systems that persist without him, and why being cheap is the fastest way to sink a shop. Plus neat oil, buying machines the right way, and a vice that took a swan dive into the chip bin.Check out Zap's IG @zap.consulting-----------------------------------------Help support the podcast www.patreon.com/withintolerancepodcast

Down the Rabbit Hole with Justin Gray EP3 - Always Be Auditing Jul 23, 2026

Show notes

Justin and Zap dig into the idea that a good tool library is never finished. They cover treating it as a digital twin of your crib, promoting tools from bench to standard, and when it's fine to let a specialty tool live outside the system entirely. The theme running underneath it all: seek perfection if you want, just don't let it stop you from starting.Check out Zap's IG @zap.consulting-----------------------------------------Help support the podcast www.patreon.com/withintolerancepodcast

Down the Rabbit Hole with Justin Gray EP2 - My Presets are Better Than Yours Jul 07, 2026

Show notes

Episode two digs into presets to boost throughput in CAM. Justin and Zap break down the golden rule—if you're dialing in feeds and speeds every single program, you need a preset—plus how far the rabbit hole goes with floor finishing, wall finishing, tape-and-glue, and everything in between. Plus why the same carbide in a different holder isn't the same tool at all.Check out Zap's IG @zap.consulting-----------------------------------------Help support the podcast www.patreon.com/withintolerancepodcast

Down the Rabbit Hole with Justin Gray EP1 - My Tool Model is Better Than Yours Jun 27, 2026

Show notes

Kicking off Down the Rabbit Hole, a new Within Tolerance podcast for nerds, by nerds. Justin and Zap launch their multi-part series "My Tool Library Is Better Than Yours" with the bootstrap basics: a simple four-folder structure, modeling your holders and tools accurately, and getting roughing and finishing presets dialed in. No money required—just stop building tools from scratch every damn time.

Within Tolerance Episode 279 - Down the Rabbit Hole with Justin Gray Jun 12, 2026

Show notes

Justin Gray catches us up on life post-Toolpath. We get into Justin Gray Labs and his vibe coding kits — along with the security nightmares they're built to prevent. He's also chasing fidget pistons to a two-tenth window on a Syil and Speedio. Then we get into Kinematic Sauce, the calibration algorithm he and Zap built for Speedios, with Fanuc and Haas next. Plus, his new show Down the Rabbit Hole is launching soon here on Within Tolerance! Check out Justin's IG @justingraylabs and at justingraylabs.com-----------------------------------------
