Super glue not drying
OP, https://en.wikipedia.org/wiki/Cyanoacrylate As cyanoacrylates age, they polymerize, become thicker, and cure more slowly. They can be thinned with a cyanoacrylate of the same chemical composition with lower viscosity.[31] Storing cyanoacrylates below 0 °F (−18 °C) will nearly stop the... -

Two part epoxy humor
Currently working in aviation, LOVE your story. If the adhesive was actually good and you ruined the test; that kind of sucks, but if the adhesive was shit, no reason to not have some fun along the way. -

Ultrasonic Parts Cleaner for Cleaning Bearings
I have been using ultrasonic cleaner 9L 540W for over 10 years now (paid $400 in 2011). I like it for certain applications but by no means it is a miracle worker for all applications. Choosing the correct solvent for the specific part is still 90% of the job. As far as aggressiveness of the... -

Recommendations for GOOD heat resistant gloves
While looking for heat resistant gloves to use for tig welding, i was not able to find a good pair that can handle heat. I can lay a ceramic fiber blanket on my hand and blast it with propane torch without feeling anything with my hand just a 1/4 of an inch deeper, but for some reason was not... -

Need a better oil free air compressors
I have been running 2x california air 1hp 8 gal compressors for a few years to do small scale glass bead blasting. They are still alive, but are rated for like 5000hrs. Point being; oilless works well if you do not need a bunch of power and you are ok with 5,000hr life. My compressors were only... -

How much useful information can i glean from almen test in blasting cabinet
I did get the saturation curve solver from shotpeener and i am getting intensity around 6-8 from different sheets they have at 60 psi. Figured the initial 90 psi setting was way too high. I did put a magnetic strip onto a 1/4" steel plate and am using that to hold the strip while blasting... -

How much useful information can i glean from almen test in blasting cabinet
It did plateau at around 20 thou, 30s was 24, 60s was 21... I think i was running at way too high of a psi setting, 100psi. Going to repeat at 60 psi to see if i can get a more sensible curve. How long do shot peening operations at say 10A intensity usually run? 2x, 3x, 10x of saturation time... -

How much useful information can i glean from almen test in blasting cabinet
How much useful information can i glean from almen test in blasting cabinet? I am playing with some steel bead S-170 blasting. Bought a set of almen type A strips on ebay. measuring thickness, prebend and final bend using a mahr indicator (good to 0.00005") on starret surface plate i get the... -

Stainless Steel grit blasting
Well, everything makes dust, but i get allot more of it from 220 grit SiC than say 80 grit beads (glass or steel). -

Stainless Steel grit blasting
Ummm.... how do you make stainless steel without iron? -

Stainless Steel grit blasting
So, i am rather interested in steel bead and steel grit blasting due to their longevity and dust less operation. Stainless steel grit seems like an ideal choice, since grit is more aggressive than bead and "stain less" supposed to prevent iron contamination of non-ferrous items being blasted... -

OT: Personal Data Collection badgering and popups
Goodbye cruel world. I'll resurrect when pop-up is gone. The cookie add-ons are pointless; they just accept all cookies, so its like clicking accept all on your own. -

ceramic bead blasting vs glass bead blasting
Tried steel bead with 220 grit SiC and while i like the result i don't like the grittiness of SiC; it just goes everywhere as compared to steel bead. Would steel grit be closer in aggressiveness to SiC or to steel bead? I like steel bead, but would like a bit more bite. -

NPT threads generating shavings and flakes during use
If i recall correctly, sodium hydroxide attacks aluminum quite vigorously. So, if you see bubbles in hydroxide solution you know its aluminum. -

NPT threads generating shavings and flakes during use
De-burring on a wire wheel or running them through NTP die should alleviate some of the install issues, but naturally a clean thread from the factory is better. The thread damage may have its largest impact not due to the amount of lost thread, but due to its burs preventing connection from... -

ceramic bead blasting vs glass bead blasting
Received steel bead today. Tried it in the cabinet and it does good job removing heavy rust and leaves nice finish. The problem that i see is that it struggles to remove certain types of oxidation. For example the thin blue oxides from my tig welding learning coupon... I tried adding some AlOx... -

NPT threads generating shavings and flakes during use
As someone that works in aviation, flight test, i must totally agree with this. Never seen NPT connections... most disconnects that i have seen are a flare or something specialized. -

NPT threads generating shavings and flakes during use
Well done plating should gouge/deform with the threads, not chip off. Very easy peeling usually indicates poor cleaning before plating. -

NPT threads generating shavings and flakes during use
I don't think you are "required" to use them for air, but tighter tolerances will make a more air tight seal.
