I'd say you'd probably be ok for light occasional use like that, even at substantially lower air pressure, though bear in mind the lower air density would logically also have an impact of the effectiveness of the air cooling of the motor, which may effect the duty cycle? Of course, the correct answer to "which compressor should I buy?" is generally "a bigger one".

Just as a guess, at 1/3 the air density you probably need 3x the cfm capability. Plus something capable of 3x the duty cycle. Cheap or effective, pick one.

I bought the Harbor Freight corded 1/2" impact wrench and the 1000LB engine support bar in anticipation of a clutch job. Hopefully neither leads to my death!! I feel like, at less than $50, the impact is worth a shot. I don't see myself needing it all the time. Though maybe that's what people say before they get a good one.

If anyone is looking for some decent/cheapish backup sockets, Advanced Auto currently has a lot of their gearwrench sets at 50% off. Just got a set of 1/4" short and deep as well as 3/8" short and deep backups for a cool ~$52. Cheaper than harborfreight at that price for much higher quality tools. Edit: They also have a bunch of other gearwrench stuff at 50% off as well, not just sockets if you're looking for something else. 100% Dundee fucked around with this message at 05:31 on May 25, 2018 |

If I take a pair of muffs off, invariably I'll put them down and minutes later be looking for them because I didn't notice where I put them down. I honestly cannot comprehend this type of stuff. I own probably at least 10 tape measures. Hell my 10mm socket is worth more than a lottery ticket some days. Yet set it down and somehow my hippocampus says gently caress off to it.

0toShifty posted:Okay, I need an air compressor, but my situation is kind of weird. The compressor will still put out whatever gauge pressure it says it will, but the capacity of the compressor will be reduced because of the reduced atmospheric pressure - essentially you're still sucking in the same amount of cubic feet per minute, but compressors are rated as if each cubic foot is at standard atmospheric conditions. You can convert from "SCFM" to "ACFM" using the following formula: ACFM = SCFM [Pstd / (Pact - Psat Φ)](Tact / Tstd) where ACFM = Actual Cubic Feet per Minute SCFM = Standard Cubic Feet per Minute Pstd = standard absolute air pressure (psia) Pact = absolute pressure at the actual level (psia) Psat = saturation pressure at the actual temperature (psi) Φ = Actual relative humidity Tact = Actual ambient air temperature (oR) Tstd = Standard temperature (oR) SCFM is typically used as 14.5 psia, 68° F with 0% RH. Formula copy/pasted from https://www.engineeringtoolbox.com/scfm-acfm-icfm-d_1012.html Long story short - the duty cycle on the compressor will be higher to achieve the same airflow rate - you need to de-rate the compressor to ensure you stay within the specified duty cycle. If you're looking at a compressor with something like an aftercooler, it won't cool nearly as well due to the reduced air density. The other area to consider is the electric motor. Typically motor manufacturers will de-rate the motor based on altitude, as the cooling fans on the motor are again designed around standard conditions - though you're usually fine up to ~5000ft (which you're above). I don't know where you'll need to go to get something like that on a smaller compressor, I'm typically dealing with a supplier and I'll just spec out the altitude and what flowrate I need in SCFM and let them size the compressor/motor combo for me.

always be closing posted:Was this in store or online? I've got time tomorrow to go in if there's anything left. I purchased in-store, but they have them listed on their website as well so I'm sure you could do either. Fortunately where I live theres like 10 Advanced Auto/Carquests within a 10 mile radius of my house so I just looked through them until I found a store that had everything that I wanted listed "in stock" on the website and sure enough when I went into the store there they were. I think you can also do in store pickup as well from their website but I've never tried that. It isn't 100% of the Gearwrench products though, so either way I'd suggest checking the website first to make sure what you want is available/discounted/etc.

The old house we bought had a looooooot of worthless junk but also came with this: The jaws are 75mm (so, 3"). That sounds a bit small but the rest looks pretty skookum to me. No markings on it apart from "75". The pic is stolen from an old ad, and is not mine, so at least two are in existence. Thoughts? Worth throwing some restoration effort at? Mine is in roughly the same shape as the one pictured.

Agreed, no down side. If you do strip it down, I had great success with painting my ~1915 Reed 6" vise with POR15. I used silver caliper paint for the body and black for the slide and it cures up hard and fast.

That vise looks awesome, and to me it seems like a vise is more about jaw travel than width. At least for what I use it for which is mainly u-joints.

Old beefy 3-4" vises are excellent. Monster 6"+ is great too but there's a lot that a smaller heavy vise can do that's cumbersome on a big one.

Is there a preferred code/OBD2 reader? Vehicles include 11 M3, 2016 honda odyssey (may be replaced with new Chrysler Pacifica), and I think I am buying an older (2000s) Toyota small truck-based SUV (4runner or lexus gx), if that matters. Also, what about a multimeter for auto and general household use? Thanks all.

If you have an android phone, Torque app plus an ELM327 reader. Define "household use" for a multimeter. Are you going to be sticking it in an outlet or measuring high DC voltage? There are plenty of cheaper meters that are fine for low voltage use but are questionable for mains power.

Someone here recommended one of these: Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles https://www.amazon.com/dp/B001LHVOVK/ref=cm_sw_r_cp_apa_i_EPCfBbV1SBT3T I picked one up to scan other cars after I got a VW specific Bluetooth dongle. I like that it's light and cheap and plug and play. Not a lot of features beyond reading and erasing codes.

For around the house? A cheap poo poo HF one will work just fine. As a side note, my father works in manufacturing and every precision HF tool he has purchased was nearly dead on when compared to the calibrated tools in their lab. I still better brands though.

Best thing about the HF ones you can basically free with a coupon. And yeah, they are fairly accurate for home use.

# ? Jun 7, 2018 01:23 |

I'd be a bit wary sticking the "free with coupon" HF meter anywhere close to mains power. Low voltage/automotive work, sure, but not something that can kill you or quickly set the thing in your hand on fire. At least spring for the $15 mini clamp or $22 multimeter if you're sticking it in an outlet.

The quality difference between the $20ish on amazon and the free HF one are night and date any the ability to tape a thermocouple to stuff has come in handy a decent number of times. I use the free one at my moms every now when I come by to fix something and the and the probes are really REALLY bad.

I agree with the sentiment about HF meters being OK for car stuff but not great for >50v AC. It's not about being accurate or not, it's about what happens if the meter experiences a fault or being used on a setting incorrectly (like putting voltage across it when resistance is selected).
