Korean arcade parts discussion

So it’s a matter of placing the Infiltration lever spool into the 309MJ grommets and go from there? I’ve the Infiltration lever and all its grommets as well as 309MJ grommets shipping my way, will be interesting to see about their sizes and compatibility.

@wazwuz I was unable to get the payment to you before vacation – did you sell my Crown set, or is there still one available?

Sorry for the trouble.

I don’t own a 301 so that’s just speculation on my part. It would be nice if you could confirm when your parts arrive.

Yes the rest of the grommet is the same shape, it did not occur to me that I might be able to swap out the middle spool. I cannot confirm if you are able to or not until later this week as I am out of town without the parts with me. Hopefully someone else can find the answer for you.

I received my Golden Crown kit, today. Thanks, @wazwuz! The decal is a nice touch. I’m looking forward to playing around with all these parts.

The spool is removable, and allows you to use the grommets that come with the lever on a 309 if you are so inclined. Good way to get a 35a and 45a without ordering from Korea, with some additional parts for roughly the same price.

If people wanna know, I just put the Infiltration 45a grommet in a 309MJ by replacing the spindle in the middle. Goes right in with no issues.

Guys, if you had followed the thread , along with Hibal’s test/review (he tested the production model before anyone here, link was posted 3 months ago… https://hibal.tistory.com/1029 ) and the various posts speaking of what was going around on Ruliweb (where the designer Yo-O gave useful info) , you’d know the only difference in design between 309 and 301 grommets are : the grommet bushing (new one looks like it’s turned delrin, similar somehow to fujin bushing) and the new 45A “flavor of the year” red gommet, exclusive to sdl301dx release, chosen by Infiltration in person .

I looked at new and very clear pics of the so called “circle-square” 301 gate , the way I see it, it’s a non regular octagon with the corner angles corresponding to the 4 cardinal inputs being equal and much wider than the other group of 4 equal angles corresponding to the diagonal input directions, all corners being smoothed/rounded of course. This type of gate is not new, there were custom parts of this type made in the past, names given were such as ‘rounded octo-square’ . With the odd 301 gate, the rounding arcs have diameters so important they’ll probably won’t make much of a difference compared to the (true) circle gate.
A seimitsu ls-56 octofoil gate design would have been much more welcome.

I wonder if the designer of the 301 got inspiration of the gate from this https://www.focusattack.com/kowal-hayabusa-octopus-octagonal-restrictor-plate-2016-model/

no, the kowal one is a regular octagon with rounded corners, sometimes called a “smoothed” octagon. All angles are equal and all rounding arcs have same diameter.
Seimitsu type has “bumps” that point inwards, simply because it’s a regular 8-foil type figure made of 8 equal arcs (octofoil, 8 overlapping equal circles, but we consider just the outline).
301 so called “circle square” according to Crown (really an octo-square, but the term is not official ) is not a regular figure as 4 cardinal corners are different from the other 4 diagonal corners (all corners are smoothed also)
This shape, including the ones I mentioned earlier are all very basic to say the truth.

A form of rounded octo-square that is of the same type as the 301 gate :

  • regular octagon with 4 corners (cardinal directions) rounded with equal arcs of R diameter and 4 corners (diagonal inputs) smoothed with identical arcs of r diameter, R>r of course. The end result is not a regular figure but the consecutive flat sides (what’s left of them) are all at the same angle.
    IMHO the 301gate does not have equal angles and corresponds more to the shape described in the preceding post.

When identifying a shape, sometimes some outlines are so similar it’s hard to make the difference, for example, the SQUIRCLE, the ROUNDED SQUARE and the TRUNCATED CIRCLE which will remind everybody of the classic square type restrictor seen in many levers. First two remind of classic Sanwa and Seimitsu gate shapes (they’re probably just a rounded square, not squircle), but also Crown SDL301 proto “square” gate ,abandoned by the way (301 proto is rounded square).

The squarish aperture on the bottom of korean levers such as in 309 , Fanta and Fujin V2 is definitely a truncated circle (no doubt there).

lol what battop work with the golden crowns?

As stated above, Sanwa LB-30 battop/balltop, including the aluminum variant.

Just about any Battop works. I’m using a 10mm Battop with a 6mm thread adapter… the thread adapters fit on the golden crown set like a glove. No issues. This is what I’m currently using. https://paradisearcadeshop.com/japroc-alu-series/1098-japroc-alu-black-battop.html

I will look into this. it should be no problem since longer screw will grip more.

hmm nvm i got it installed but the actuator doesn’t seem to reach the switches to activate them hmmmm well on the one to the right it doesn’t

pretty sure the left it a 303, and the right is 309 which i thought this was for doesn’t work? seems to work on the 303 though

I’m sorry, for the moment the fist batch is sold out, but now I’m working on second batch

thank you for the update, please share your experience with us

make sure you don’t accidentally put the actuator upside down, the bigger diameter is on top (inline witch the switch lever)

hahaha, i dont think i did that but maybe. thank you for the reply

@Quasimoto thats a crown 307 on the right they have longer shafts and larger acuators golden crown wont work with that lever
