Hi. I have two identical templates that help align parts for gluing. They are equilateral triangles made of 1/8 fiberglass sheet. I have to enlarge three internal slots from 3/16 to 1/4. I was thinking of using a sanding disk on the table saw. Two questions:
1) What would the best tape be to...
I have a 12 inch piece of 1.75 x 1.625 alumining (6061-T6) tubing. It should be 1.638 (a little more than 41.6mm) ID. So I need 0.013 inch off the od, or about 0.0065 off the ID. The exact OD of the tube is not of super importance. I don't have a decent lathe to bore this. I don't have a...
I am asking about the best (cheapest) way to make carbon fiber ring shapes with non-standard cross-section, of about 1.5-4 inches in diameter.
So I am thinking of getting back into model rocketry after many decades. The big boy edition is called High-Power Rocketry. As in 98mm diameter...
All,
I have a Dell workstation. A T7910, with dual Xeon processors. Probably about a 6 yo design, but it works. I put pretty spifffy CPUs (E5-2699a - 22 cores each) in the thing and to get something that generates the same benchmarks I'd have to spend about $18000. I run computer models of...
After 40 years of marriage, the spoon part of our teak salad tongs has broken. The wife and I have a fondness for these tongs. Is there a good food safe adhesive that will work with teak?
Also I have to clean out some of the crude that was in the crack that has been there for a while. Dawn...
All,
I have a pretty powerful workstation from a few years ago. A Dell T7910. Dual Xeon processors, 128Gb memory. I run an Nvidia 2080 Ti video card and it's pretty awesome. The one problem I have is that I upgraded my CPUs to model with the highest performance level (E5-2699A v4) that the...
Ok, not an industrial question, but...
My wife dropped the lid to our instant pot. The lid has a handle on top, and two ears on the side, all cast in a phenolic (matte finish though) plastic. One of the ears got cracked. not completely separated, but cracked and week. It's an area with a...
I'm doing some factory-suggested mods to a guitar amp (Fender Prosonic - a tube/valve amp). I need a 27K 1W resistor. There aren't any in stock at Mouser. So I bought 4 1/2W 27K resistors. Solder two assemblies of two resistors in series, then solder the two assemblies together in parallel...
Hey der, PM. I wanted to share a positive experience with Mouser Electronics. Placed an order. Just after I hit the "Commit Order" button I realized that I'd forgotten some items. Called customer service and they stopped the order, added the items and replaced the order. For a couple of...
I was riding my bike and noticed this off the road in a driveway at the local fire department. It's chromed and shiny so I noticed it and wondered what it was. Any ideas?
On another site, someone wanted the proper drill size for a M6 (6mm x 1mm pitch) tap. I suggested number 6, 7, or 8, or a 13/64. In the range of 5.05 to 5.18mm. I got a 13/64 (5.159mm) giving you about 77% thread engagment. Others suggested that the standard drill size for M6 is 5mm. They...
With 20+ years in the house, and because during all of them we said "Put that unused _______ in the basement", we finally started to clean the basement. One day each of the last two weekends, 7-9 hours each day, and the job is still a couple of weekends away from finishing. On the plus side...
I have an old (2006, 5th generation) Ipod. I keep it because the A/D chip (sound quality) in it is superior to later versions. I've replaced the hard drive with a SDHD. I also replaced the battery, which didn't last. Anyone have any luck (durability wise) with replacement batteries for...
I'm restoring a couple of old bicycles. Also maintaining some new ones. Two things I'm concerned with are
1) Cleaning the crude out of old chains, brakes, derailleurs, and such, and
2) Polishing small aluminum (and other metal) parts like brake handles, hubs, etc.
For the cleaning, I've...
So I have a junction box on the gable above my double garage door. I have a dual floodlight up there, with a motion detector. Problem is, it doesn't last. Any recommendations for a really durable floodlight/electric eye/motion detector setup that will fit up with a 4x4 jbox?
The c**p at...
Well, I just bought a 1978 Schwinn Superior. The tires were rags, so I put my old Paramount (Campy Nuovo Record, Mavic Rims) on the thing. Handles like a dream - should be a good ride. That said, I'd like to get the thing back to "all standard" using the original 27 x 1-1/4 wheels. I could...
I realize that this is kind of overspecified. But I'm trying to corner the highly lucrative slide rule repair market. Pickett rules of a certain vintage use this size screw to hold the thing together.
Oh yeah, if the screw were of the slotted mushroom head type, it would be great.
Yes, I...
