Show notes

EINSTAR Scanning And Object Replication - We used the EINSTAR to scan and replicate a Thumb CMC Splint. It's a very organic shape and it weren't easy. Peel Grinding Success for Lapzetti Plates - Peel Grinding is an interesting technique introduced to us by Adam Demuth ( @adamthemachinist ). It was a win for an application we did not predict. Ford Lightning 20K report... and More! - 20,000 electric miles, and... spoilers!... it's been great.

Show notes

Bambu Filaments Shakeup! PETG-HF? - TWO of our favorite filaments are discontinued, forcing us to evaluate replacements. Inventory is good for a few months while we do that, but initial experiments indicate a possible overall winner. Pining For The Fjell - A Grimsmo Visit - We had a nice social visit from John Grimsmo ( @JohnGrimsmo ) and his kiddos. Pizza was consumed. Knives were discussed. More importantly, I was bequeathed a Norseman, and got to fondle the Fjell. They are BOTH awesome.

Show notes

Tom Lipton ( @oxtoolco ) and Robin Renzetti ( @ROBRENZ ) collaborate on a tight-tolerance design of a rotary grinding attachment. Each has different requirements, and the cross-pollination of knowledge is of huge value. Notes will be taken. Knowledge will be gained. ----- Save $500 at FormLabs by using my referral code at the Links page, below.

FormLabs Rigid 10K... It is! - This resin is highly glass-filled, and it's amazingly dense and stiff. I am testing it for it's electrical properties at RF frequencies! https://formlabs.com/store/materials/rigid-10k-resin/ Fanuc, Haas, and Batteries... Oh My! - I use a product from Haas to solve a Fanuc problem. But, the origin story of this product has a twist.

PFG.Live 2024-0714: Prototyping Precision Paper Punchers with Adam Demuth Jul 14, 2024

Show notes

Guest: Adam Demuth! - We catch up with one of our favorite toolmakers and learn of his recent exploits. Recent projects include some fun ceramics projects. Prototyping Precision Paper Punchers - Precision paper punching at a distance is an interest shared by many machinists, and Adam and Spencer are no exceptions. We discuss Adam's designs and implementations. His innovative use of his grinder in precision "shaping" is unique! The Artwork of John Moses Browning - putting things in perspective, in particular some of Browning's work from 1911. It is reported that he is responsible for some long-playing 45's, which have still not been replaced by CDs or DVDs. And, of course, more...

PFG.Live 2024-0630: Killing the Elephant's Foot Jun 30, 2024

Show notes

Direct to Build-Plate SLA - We are so used to seeing SLA (resin) prints on supports, we forget that direct-to-buildplate is possible. The DAMTEE and DAMKEEZ projects were examples of parts that take advantage of no-supports. Lessons were learned in failed prints when we made the MOLY-2 holders. We're getting the hang of it. Killing the Elephant's Foot on the Form 4 - When you print direct to the build plate, there is an "elephant's foot" at the bottom of the print. This is there for good reason, as it is in FDM printing, sometimes. The mechanism is investigated, and a mitigation is tested... successfully. Hearing Protection in the Shop - Please! - We look at specific recommendations, both Bluetooth-enabled and not. Costs range from 20 cents to about 20,000 cents. ----- Save $500 at FormLabs by using my referral code at the Links page, below.

Show notes

Solopreneurship: Stay On Target! - It is not easy recognizing when you are drifting off course. The gifts of collaborative on-line tools. Making hard decisions. I Really Need to Vent! - Putting an electronics enclosure into a harsh, marine environment. 'Tain't easy. To vent or not to vent an enclosure... that is the question. 3D Scanning: Non-Trivial - We have an intern starting from zero, trying to use our Einstar 3D Scanner to produce a good solid model.

PFG.Live 2024-0616: Housing Design for Extreme Environments Jun 16, 2024

Show notes

Solvents in the Shop! - Some are benign, some are downright dangerous. Choose wisely and use them safely. Three-Step SLA Support Recipe? - I have come up with a recipe which may be useful in many SLA situations. The speed of the Form 4 printer caused me to rethink my recipe with good results. Housing Design For Extreme Environments - I am in the middle of a design for a client, and it's got me thinking about the rules for making equipment housings in different environments. From beneath the sea to space and everywhere in between. OK... mostly between. ----- Save $500 at FormLabs by using my referral code at the Links page, below.
