|Thread: Unkown plastic|
My wife has an empty cosmetics jar. It's quite small and looks and feels very much like cut crystal glass. The fingernail test says glass, but the tooth test says plastic. Any idea what it could be?
|Thread: Amazon Prime scam?|
My phone and internet are from TalkTalk, both of which work fine. The phone has an optional, free, call screening facility. Calls from whitelisted numbers are passed normally, all others must state their name which is passed to me when I answer. I can then whitelist the number by pressing 1, accept it this time only by pressing 2, or rejecting it by pressing 3. Since using the service I've had almost no spam or scam calls.
As a teenager in the 50's I remember a shop sign (outside a tailor's I seem to remember) that said 'Quality is remembered long after price is forgotten'.
|Thread: Broken drill bit in hole|
Sorry to disappoint. Making small tube is not difficult, just time consuming.
I made the tube from 0.5mm sheet, which I first rolled down to 0.25mm and cut a strip just a little wider than the circumference of the required tube. I cut one end of the strip into a 'V' and then used a swage block, and a series of suitably sized rods, to bend the strip lengthways into a 'U' shape. The end of the 'V' was then poked through a suitably sized hole in a draw-plate, and then pulled through to start closing the 'U' shape into a circle. Smaller and smaller holes were then used until I had a hollow tube - albeit too large an OD - which I then soldered along the seam. I then used smaller and smaller holes in the draw-plate until I reckoned it was just right for inserting the iron wire. With the wire inserted I could then continue using smaller and smaller holes until it got to the required OD. After a final annealing I could then coil the tube around a former to make the required helix.
Acid then got rid of the iron core.
|Thread: Centering Microscope|
When I was in my teens, and blissfully unaware of the problems, I dismantled a pair of binoculars to clean them. Even now, many years later, I well remember the frustrating days I spent re-aligning the prisms. But I eventually managed it.

Using pickling acid will certainly do the job without harming the copper. Heat it up to speed the process.
I once made some earrings from 1.5mm OD gold tube. The tube was made with a core of 1mm iron wire to support it when it was coiled to make the helix required for the earring design. The iron core was removed by immersing the helix in 10% H2SO4. I had to heat the acid, but it still took about 2 days to remove all the iron.
|Thread: Old School Drawing Exercises and 2D CAD|
Here's a test that might be of interest. The yellow spot indicates a tangent.
My effort was done with Fusion sketch. What's wrong with it?
How about this?
I don't see how that works.
I tried it in CAD and the final circle, whilst tangent to the base, doesn't touch the other two sides.
I made this knurling tool some years ago and kept it in a cupboard together with 4 pairs of different knurls in a plastic bag. I often toyed with the idea of making a fitted box for it, but was put off by the awkward shapes. Eventually I bit the bullet, designed the 3D model in Fusion and am about to 3D print it.
2D CAD would have been very difficult.
No CAD, no compass, no ruler, just pencil and trig.
Do I get double points?
Pretty easy with Fusion, and the areas are equal.
|Thread: Free or inexpensive 2D cad for clock wheels|
You could probably get an old copy of TurboCAD PP on the cheap. This was done in TCAD V16.
|Thread: Comparative Strength of Loctite|
It would interesting to compare with epoxy and superglue.
|Thread: Digital angle gauges|
Just to put 0.1 degrees into perspective. When using a 5" sine bar to set an angle of 45 degrees, a 0.1 degree difference would translate into a height difference of about 0.006". For 10 degrees it works out at about 0.0085", and for 70 degrees, about 0.003".
|Thread: Constantly Having To Log In To The Website|
This has also started happening again with me.
Sometimes, when I login, I have the option 'remember me', and other times not. It seems to me that, if the option was provided, and I use it, then I usually stay logged in for a while. If it's not available then the login is temporary. The last couple of times I've had to login the 'remember me' option was not available.
|Thread: Weeds in a 'lawn'|
After I cut the 'grass' last week I Weedoled it, but the unwanted flowers have re-appeared. I'll try cutting and Weedol again tomorrow - if it doesn't rain.
It's probably apparent that I'm definitely not a gardener.
