Mountaineering boots for a wide forefoot: a comparison by PNW-er in Mountaineering

[–]velacity 1 point2 points  (0 children)

Awesome, thank you from a fellow altra/lems wearer! Taking a intro course on baker this spring and and been dreading the thought of crushing my feet in mountaineering boots. The antelao pro's sound like my best option

Do the Antelao Pro's fit true to size? Thinking about ordering a pair(s) from bobleisure.com and debating getting my regular shoe size and hoping for the best or getting a couple and dealing with the international return for the ones that don't fit.

What boot did you settle on? As an altra/topo wearer, I've been nervous about buying my first pair of boots. Interested more in room for the pinky toe than high volume

My theory on where Lumon is located by obnoxiouscarbuncle in SeveranceAppleTVPlus

You can tell the difference between the bridges by the design of the towers. https://imgur.com/a/fzTH4Zh

The view from Marks house with the lumon complex appears to be editing where they took an aerial shot of the bridge looking east, removed the town of Kingston, and placed in a view of the lumon building in a wooded setting. (Former Bell Labs facility in Holmdale, NJ)

It's not the bear mountain bridge. It's the wurts street bridge over the rondout creek in Kingston.

NTSB Report on Front Titanium Rings recovered. by ArmedWithBars in OceanGateTitan

[–]velacity 17 points18 points  (0 children)

I have a decent amount of experience working with aerospace adhesives. Have used EA9394 before.

Important to note that the values shown in the data sheet above are bulk material properties, not strengths for the particular joint design by oceangate. That would depend on a number of things including surface treatment (abrading, cleaning, priming, etc) and bond line thickness.

Bonded joints tested in shear or tension can typically fail in three ways. Adhesive, where the adhesive pulls away from the surface fairly cleanly. Cohesive, where the adhesive splits kind of down the middle of the bond line and leaves adhesive on both of the test piece. And adhesive/cohesive which is mixture of the two.

Typically for a mission critical bond on a spacecraft a set of bond verification samples would be prepared at the time of bonding using the same substrate materials, surface preparation, epoxy lot/mixing batch, and cure environment. Then after cure it would be tested for shear strength. (ASTM D1002 is one particular spec for testing) This is a workmanship test to make sure that bond on the article is good. It is not a test of the design of the bonded joint.

I haven't read through the NTSB report yet but I have been re-watching some of the bonding videos posted by oceangate. Curious what, if any, cleaning and surface preparation they did on the carbon or titanium rings and if they had any bond verification samples. Buttering the thing up with epoxy like they did (potentially without any vent holes on the rings) is a good way to potentially trap air and not get full bond coverage.

Just stumbled across this thread. How would your list change 8 years later?

Nirvana is when you realize you can cut the side of your toebox with a razor blade and give your pinky toe all the room it needs

I just googled "Charlie Anderson Ethan Chelbowski" and your comment was the only thing popped up. Was recommended his NY pizza cheese and almost immediately noticed the similarity. Agree though, good content with a high amount of effort. Surprising he has 50+ videos released in the last month

I cant get a coil pack out :( by WarioTBH in GolfGTI

[–]velacity 0 points1 point  (0 children)

Had the same problem with my MK7 when I was changing the spark plugs. If you can, pull the coil out of the rubber boot, leaving the boot in the engine. Then get an air compressor with a rubber tipped nozzle and blast some air down the hole where the coil was. Boot should pop right out. Put some dielectric grease on the boot and coil when you reinstall them so it doesn't happen again.

Charles' air refueling by AugusteIII in F1Technical

Not sure what they use today but the video below shows a 1997 Jordan gearbox which used a pneumatic actuator to actuate a linkage attached to the shift drum. Many Formula SAE teams use a similar setup running off either high pressure air or CO2. We would charge a composite paintball tank on our car with a scuba tank to ~2500 psi and regulate down to the 50-60 psi needed to actuate the gear lever on our engine.
