I have been looking for 1/4 28 cones, or short spikes, I can't find any. Does anybody know where I can get some?
This is the OEM thread size for Simaudio cones. I have flat cones installed from the factory and want to change to pointed cones.
Follow Ups:
Well the easiest solution was a set of the older OEM Moon pointed cones and thanks to a user on USAM in Canada, I now have a set residing happily under me DAC now.
Hardness and shape are the primary variables, with very hard materials and ballistic shape being the superior qualities. Thus, very hard materials such as NASA grade ceramics and hardened steel will outperform brass, aluminum, carbon fiber and rubbery type materials, with ballistic shaped cones outperforming cone shapes.
You can drill and tap any smaller thread size hole for 1/4-28. The only challenge is holding a cone in a vise. Place rubber jaws in the vise for a better grip.
Alternatively, you can drill out the threads with a 1/4" bit and glue in
some 1/4" rod. Then drill and tap for the correct thread size of new cones.
Novus Ordo Seclorum
Is 1/4-28 a standard thread size. NF.....National Fine......
You should have NO trouble sourcing this from any reputible hardware house. The home stores may carry only NC, which is 1/4" size is 20 threads per inch....
Too much is never enough
1/4 28 is a standard thread size, but not for cones, most use M6 or 1/4 20. I had put an ad up on USAM and got a response within a day, found a guy with the original Simaudio cones and bought a set from him. They are on their way to me from Canada.
Good find!
1/4-28 is an NF size. (National Fine)
While?
1/4-20 is in the NC series. (National Coarse)
Every camera I've ever owned has been 1/4-20 to match USA protocol for tripod.....
And from our 'Too Much Information' department?
See link for chart. Both NF and NC are listed for ALL common SAE bolt sizes....

We understand why Simaudio went with the flat-bottomed cones/spikes. They won't scratch the shelf, or puncture your hand or foot.
But they just don't work. They do not hold the component to the shelf. Despite the mass of Simaudio Evolution gear, if you push a button, that action will cause the component to be displaced. The flat-bottomed cones do not provide any adhesion to the shelf.
The spike-and-cup combination is much more effective. The dimpled cups have a sticky underside. Do be aware that, over the years, the spongy or rubbery material will disintegrate.
We recommend that one person holds the component up, while you position the cup. She will then gently lower the component's spike into the cup.
Sorry, we do not know who makes that thread size, or where to find some.
" She will then gently lower the component's spike into the cup."
That sounds like fun, Lummy.
During the 1992-93 school year, I actually had stereo components in my college apartment. But initially, we did not have a rack. We had to stack the components, TV, and SNES on coffee and end tables.
Seemingly everyday, at least one neighbor, friend, classmate, or relative would come over. They were almost always coeds. Above was Olivia, while we were on Santa Cruz's West Cliff Drive, which is now crumbling into the sea. Anyway, Olivia came over a few times. While my lazy (male) housemates sat on the couch or floor, cooked and cleaned in the kitchen, or ate on the kitchen table, Olivia and I experimented with AQ CD Feet and Sims Navcom Silencers. We called these products "footers." At that time, we did not have any spikes or cones (at home in S.F., I used Simply Physics Tonecones, plus the protective plastic cups).
I do not recall where or in what context, but in the early-90s, I came across the line, "Sounds kinky, but isn't." Ever since then, I've occasionally used that line, when writing about audio.
At my home in S.F., my friends Scylla, KJ, and ACS (all three are female) helped me lift, hook up, and disconnect stereo gear. All three got scratched, by the Muse Mode 100's sharp chassis edges and heatsink fins. The Muse amp did not come with footers, so you had to use your own. The girls (they were in their teens, then) would help lift components, while I moved the footers into place. Anyway, ACS has always had this penchant, for making everything sexual, even though it was not. She herself would then use the line, "sounds kinky, but isn't."
Aaron 01's Simaudio Evolution components are not lightweight. He really should enlist a second person, to help him screw/unscrew the threaded cones, and move the component(s) in place. If he does not have any help, he could use some sort of blocks, to prop up the component, while he adjusts its and the cones' positioning. Paperback books, Lego Duplo, and chalkboard erasers all make good props.
" He really should enlist a second person, to help him " Gosh Lummy do I seem that old and feeble?
I will have you know that every other day before my morning coffee I take my 700i out of the rack and do 3 sets at 10 reps of one arm curls with it :)
I am with you on the flat cones not being the best, hence me wanting to change them, I only have them on my DAC. As per other suggestions I think I would have to modify any other cone besides the Simaudio ones and I may do that down the road. For now I put up a wanted ad on USAM to see if anyone is willing to part with a set from an old component.
Also you are the same guy telling me I should be schlepping these components in and out of my rack to change the fuse directions. I will wait until you are in Colorado to help me move these in and out.
Flat. Not only were there no waves, but there wasn't even whitewater. So just lie on your board, enjoy the Hawaiian sea and sun, and daydream about audio.
When you think about the Simaudio 700i's 60 pounds, it's not just its mass. It's the bulk. That's not a reflection of its owner's physical capabilities. So if possible, enlist an able-bodied person, to help you.
Here are the flat-bottomed cones/spikes. Their flat and polished surface makes them slide on whichever shelf they are placed. Since we have multiple Simaudio Evolution components, we do have the "Bridges." But these spacers, which allow the stacking of two Evolution components, are now a whopping US$540 for a set of 4.
