Since it doesn't even have to take stress, much less be particularly strong, you could form that stuff around a wood cylinder of whatever diameter and then epoxy the join with something like PC-11.

But a soldered join would also be fine. Or it could be crimped, or stapled, or brazed, or welded, or stitched together with leather or thread or wire or anything really.

Or riveted! I bet pop rivets would work fine, look ok, and they're cheap as hell and are installed with a light hammer.

Hmm, consider brass sheet, too. It's much easier to work with and join. It can be blackened chemically if that is a consideration.

You could go thinner too, and at that point you could just electrochemically etch your sheet (brass or steel) for totally custom designs.

Might be a stupid question, possibly even an wrong thread, but have anyone of you tried to make an acoustic guitar/Kantele out of metal?
Does the metal as an material cause any problems withs Sound box and the way the instrument sounds like?

Ever use PL Premium? I used to use epoxy until someone introduced me to that stuff. The only problem is it comes in those caulking gun size containers.

Problem is the wrong word, but definitely different. I have not built those instruments from metal but I have listened to stringed instruments with metal sound boxes, they tend to be brighter, colder, or twangier than wood box instruments. Look up resonator guitar and 'canjo' for an idea.

Those are all really good suggestions -- thanks! I've used pop rivets before, so at least on that end I have some experience.

I'm digging this too. It would require some experimentation to get the right brass thickness + etch time combination without the lateral etch completely eating away under the mask. Hmm. That could be interesting.

edit: Isotropic etching, that's what I'm talking about. I remember some of my semiconductor past after all.

Does anybody know of any good repository of blacksmithing twists? I have to build a table in the next two weeks and I wanna work a lot of twists into the legs and braces 'cause it isn't something I've explored much yet. I know the basics- the standard twist appearances with different stock profiles, reversed twists, grooved twists, multibar rope twists, pineapple twists, those funky cube/Rubik twists, etc- but twist possibilities are "theoretically infinite" and yet you only really run into a small clutch of them in common use.

Made... this. As an excuse to practise consistent twisting and reverse twisting. Still managed to put one extra reverse twist on one of the segments by accident, lost count of my rotations.

Thanks for all the advice on CNC stuff, I finally got the hang of cambam, and this weekend I think I'm gonna turn this to brass. I got scraps of this PVC finishing board, it mills super easy. I used a 3mm 2 flute endmill instead of the weirdo 6 flute 1.941mm thing that came with my dremel. I did set the depth pass to 0.1mm so it took a lonnng time to run, but my machine is not rigid enough to do much better I think.

Feature, not a bug~

e: the weight was discussed and the 1.8 pounds it works out to is fine. 3/8" or even aluminium, if I were doing simpler cold twisting/embellishment, would probably be preferable in general.

So long as it isn't being used for suspension work, then joints won't have a ton of problems with the weight even up to 5lbs. The shackle/manacle is usually where issues arise with weight or rigidity since the weight isn't usually distributed as evenly as you can with a spreader bar.

Not that I have any knowledge on this subject. :redass:

I had no idea there was a market for blacksmithed S&M gear, but I guess I shouldn't be surprised. How much does something like that spreader cost Ambrose? Just asking for a friend.

In non-kinkchat news, I cut out my pattern and did some light sanding:

The cockrings I've sold wholesale lots of retail/ed for ~$50, but I only scraped back a fraction of that; that spreader'll probably go for a friendrated $50 too, but you could ask a lot more from the right buyer. Not bad for an hour and a half's work.

The big catch with making gear is: you have to be able to 'vouch' for it. You have to know that your design works as intended and is comfortable and as safe as can be. Something like a cockring isn't too hard- has to have a standard-increment ID, has to be well-finished and have no hard internal edges, that kind of thing- but more complex gear is much dicier. Either be a freak or have a freaky friend who's willing to crash-test your poo poo as you iterate your designs.

According to local legend, a student in our shop once made a dildo for his girlfriend as a present. Idiot decided that aluminum was a good material choice. Yeah, not so much, she ended up in the hospital with aluminum toxicity. At least he didn't use the ultra-machinable brass, I guess. Lead poisoning isn't very romantic.

Aluminum is actually one of the better metals to make sex toys out of- it's markedly innocuous and nontoxic in contact with skin, and its insta-self-healing oxide layer shrugs off the harsh and varied operating conditions of the bedroom, particularly if anodized. Anything involving penetration has to be anodized. Not as good as titanium or stainless steel but still a viable option for most applications :eng101:

I actually just repaired the power supply for the anodizing station at school right before spring break, and we did just get in some 2 inch aluminum round stock in. Hmmm. HMMM. Wonder how my ultraconservative instructor would react when he asks what I'm working on and I tell him a butt plug.

The anodizing is to keep the aluminum from getting damaged or discolored. Aluminum isn't toxic and I've never heard of anyone being allergic to it.

Aluminum toxicity has to do with people with acute renal failure taking medicines containing high levels of aluminum.

Hmm, I wonder if shoving aluminum into your rear end might involve some aluminum making its way into your blood stream through micro tears in the anus or by being forced deeper into the intestines by the action of the dildo.
