I've got a part with a bayonet feature on one end that another part will lock into. I'm not sure what is the best way to ensure proper position of these features to the ID bore and to each other. The mating part will slide in the bore and have a cross pin that has to slide in the slot on both...
I'm trying to open some files from 1997. Pretty sure they are spreadsheets but I don't know what software. I've got.WB1 and .WK1 files. Excel 2016 doesn't know what to do with them and if I do open them it's gibberish. Are these Quattro files? Any tips on how to open them...
I'm looking at the figures in https://www.marcorubber.com/o-ring-permeation.htm
The greater the thickness in the permeation direction the smaller the permeation rate, right?
I think the D dimension should be at right angles (horizontal) to what is shown...
Prechamber Combustion for Future Honda Superbikes?
Interesting adoption of F1 tech to high performance street bikes. I can see some real benefits to that rotating shaft between the pre-chamber and the combustion chamber but also some potential problems with carbon build up, oil seal leakage...
I've got a very old material spec that calls out Izod Notched Impact Strength of 1.5 ft-lb/in (80 J/m) to ASTM D 256. I've got a Chinese data sheet that gives Notched Impact Strength of 10 kJ/m^2 to ISO 179. Note: does not say Izod. Any way to compare these two values or is it totally apples...
I'm sure this has come up before but I can't find it. I'm looking at a short cylindrical piston in a bore and trying to determine at what combination of clearance (tilt) and friction coefficient the piston may become wedged in the bore. Also, does anyone have info on steel on steel friction...
I'm trying to make a histogram of some QC date in Excel 2016. The MS online help says to select the data and Click Insert > Insert Statistic Chart > Histogram. I don't have any "Insert Statistic Chart" option on the Insert tab. Alternatively, you are supposed to be able to pick Insert >...
Came across this on the interwebs without any explanation. Can't really see what all is involved here, any ideas why the coin(?) is spinning & levitating?

I got back home last Wednesday night from a week of vacation to find my house air conditioning out. I could tell there had been storms and power outage(s). My ~50 year old house has several rooms with built in lighting using the old fat 4' fluorescent tubes. About half of the tubes were not...
We have been using Nitronics 60 (UNS S21800) foil for over 30 years. It gets processed through multiple stages from the ingot to the finished size. The people who do the finishing passes say they are no longer able to get it. They buy it in coils that are 0.062" thick by 13.5" wide by 150...
I've searched a good bit and I can not figure this out. I have a number of files where the name box is missing. This is the box that shows the name of the cell you are in or when you start to type a formula it gives you a pull down menu of recently used functions. It should look like this...
So I'd clung to Win 7 for as long as possible but with MS pulling the plug on support, sys admin said I had to upgrade my workstation to Win 10. They did what seems to be a decent job of it, looks far more familiar than any of the other Win 10 installs I've seen that look like a freaking phone...
Anyone have any experience with these guys?

Since the rick house failure thread at the same distillery is closed, I started a new one.

I have a customer returned part that has clearly been overheated. The strange thing is that when I cut it open everything is covered in what appear to be glass fibers. I have never seen this before. The nylon 66 30% GF bobbin has been melted in places but I've never seen thousands of fibers...
We have a magnetic component that is blanked from AISI 8620 which we vacuum anneal for magnetic properties prior to gaseous nitrocarburizing to give it a hard case. This whole process was developed initially for similar parts made from 2.5% silicon iron which has worked well for 30+ years...
I've seen numerous online listing for 440C stainless steel products such as ball bearings as "440 DFAR" but no explanation as to what the DFAR stands for. I know that it is NOT referring to the Defense Acquisition Regulations System. I also know that this steel is air melted, not vacuum...
Not a lot of detail here but looks like it could get ugly.

We ion (plasma) nitride austenitic stainless steel components for wear resistance, have been doing this for many years. These parts are short cylinders that we put in a plate with pockets during heat treat so only the top is exposed to the ion source. We do not do any welding to these...
In the past (WF4), I was able to load a font called Strikethru which did exactly like it sounds, put a horizontal line through the middle of all the characters. This font is identical to the default font font with the strike through. We do this when we have a note or line in a table that is...
