The Secret Society of Lathe Trolls

So, the diameter inside the pipe is 13/16ths...odd. Thats measuring from one thread crest to the other on the opposite side with my calipers. The thread pitch was harder to measure as you cannot actually get in a look to see the gauge resting on the threads as its a small hole and blocks all light ...

LOL jeeze I really do want to buy this, that is, if I had a wild surplus of money. It would be tenaciously interesting to see how this thing was done. There of course is a risk that its largely made out of wood or something gruesome like that.

Indeed a mysterious object.

If all else fails you could have someone Braze it together then paint it to keep things neat eh? Quite a realistic idea indeed. Even more obtainable, clean, and reversible would be to epoxy a new insert inside this opening that acts as a reducer down to something common in lighting. This could be d...

which are really good.

I'd love to see photos of this sometime!

It will be good to measure the thread pitch on those internal threads, with a thread gauge like the one pictured here: Screen Shot 2016-02-18 at 2.12.03 PM.png You will also need to measure the width of that opening– both of these operations could likely be 'guessed' to a pretty good degree. There a...

I believe it is trivial to need measurements on this part, because you can make or have one made over a wide variety of dimensions and it should work well provided it: can accommodate a belt [if you are going that route], and it does not collide with any parts on your turntable [particularly the ton...

That is a gorgeous K8; looks to be in pristine condition. Where on Earth did you find it? Has the advance ball, too. Wow! Is the rubber tire in good condition? What does one do if it isn't? If one is need of rubber roller repair, it is essential to visit the expert on rubber roller repairs. One mus...

It is made of titanium for German knives, I thought over this week as you do with this material [titanium, titanium can be soldered tin]. I've been doing this handle on the knife 10 minutes. :mrgreen: :) Hey sakuszi, cool part!! Where did you find this? Do you have a link? I did this handle a drill...

This is amazing!!

My mini-router dremel tool came with a bunch of different bits, one of them looks like this:
This kind of thing might work?

What is the taper angle on those styli?

I know about heating wire, but I think heat will decrease the lifetime of these "cheap ebay HSS", but I try it tomorrow. I've enough konstantan-wire here around. Heaten up the PET-G with a heatlamp ended in a warping plate. My grinding machine got 60U/min an so the hole process lasts more than one ...

Have you tried pressing discs instead of strips cut for the cone? I'm not sure I understand. The press method starts with a flat disc of aluminum can material that I annealed with a torch to soften. Then into the die and press. What comes out is one formed cone with excess around the perimeter. Yes...

Looking great, Bryan! Looks like that pressing method is going to work well for you! Have you tried pressing discs instead of strips cut for the cone? I don't imagine a disc would be any easier, but with the correct gauge of metal, it might work. I don't want to send you on a wild goose chase, and I...

What material are you making the final "cone extensions" out of? Are those also going to be spun aluminum? Hey Bryan, I failed to mention the method I have come to to form the cylindrical members of these parts: Basically I put down a soft pad and roll the pre-cut aluminium strips into a cylinder u...

I managed to assemble a rough prototype of the bobbin and cone structure I am considering for my design. The bobbin portion is made from a beverage can, the conical transition is made from spun 29 gauge aluminium sheet stock. The two pieces were positioned on an aluminium jig and superglue was guide...

Alright here's a first go at it with the tool: spinercone.JPG More of the same, but looking better and way easier to complete. I should mention that I have been experimenting with a number of gauges of aluminium sheet, and I have come to one that works very well. 0.0011" = [29 Gauge] : sheet stock -...

Finished up the first tool for spinning. Yet to try it, but I will report back when I do.

Hey there Scotty, That adhesive looks unique. At the end of the day, it is simply a glue with aluminium dust in it, I believe. It certainly may add structural rigidity and other adhesives are found with this composition. Here is one that I have in my adhesives collection that is tried and true, this...
