The Sanwa and Seimitsu FAQ

Are there any stiffer JLF springs?

^
nope and that is my main gripe with the JLF. It makes the relatively long throw so much more significant for the stick. Like on Happ Comp w/ hard spring, good P360, or Fanta sticks you don’t notice the throw so much as they return to neutral so fast but JLFs don’t so they are horrible for marvel and shmups. This problem is compounded even further if you use the octagonal gate. I believe TheRealNeoGeo said you could add an LS-32 spring to it to make it stiffer. I have not tried it myself but you can buy the springs from lizard lick for like a buck.

A buck plus shipping… the sticks are good at first, but once they start wearing and getting “gummy” through the throw, they get stuck (so to speak) returning to neutral. I can’t dash very well on mine now, even though I just pulled it apart to clean and lube (with petroleum jelly).

It’s too bad, really. The square gate is nice. Do you put the LS-32 spring concentric with the existing spring, or is it just a drop-in replacement?

uppity

One of my JLFs has the same problem. no idea about the spring though. I presume there is no harm in trying both.

I played with both the JLF-SP and LS-32-spring in my JLF and it is so nice :).

Not too sure if it’s the right thread for this Oo…
Is there somewhere where I can find the exact measurements of the following panels:
Blast City and Astro City?

Thanks

So you use both at the same time? How is the stiffness compared to the standard Happ spring?

how does that work?

you just put one over the other or something? (stick noob here)

Both at the same time, yes. It is really stiff but it is hard to compare it to the HAPP because it is a much bigger joystick. You have to try it :).

Just put a LS-32 spring over the regular one, yes.

That sounds awesome per. I think I will try just the LS-32 spring and if that is not stiff enough then I will use both.

Imma try that too

I got some mounting plates from Ed at Arcade-In-A-Box that replace the ones on the Ultimarc sticks so they can mount into an area made for Happ sticks. Here is a pic:

Can anyone tell me if these will work for Seimitsu LS-32s? Pic again:

From eye-balling it it looks like it could work.

What is up with the measurements on some of these joystick diagrams? (I’ve had problems with the Happ diagrams and others have mentioned that too). I measured and routered the recess for my JLW-TM-8 based EXACTLY on the diagram (3mm deep recess). It was supposed to leave the stick height at 23mm above my plexiglass (based on Paik4Life’s info at the beginning of this page). The mounting plate for the joystick is even with the wood, so I thought everything was O.K. After measuring the stick, I now notice that the stick has about 1.2" (31mm) of shaft above my plexi, which is longer than the 24mm that I was supposed to have. Is this too long? Should I re-router and re-mount the stick or leave it? What the heck did I do wrong? Will this affect the performance of the stick? Any help that is given would be much appreciated. Thanks!

It will not affect performance.

Going back to using the two springs thing:

Just to make sure, by “over” you mean one ON TOP of the other, or placed so that they both intertwine with one another?

I don’t believe you will be able to stack them on top of each other. The diameters are likely different, so you can put one inside the other without coil interference.

ninjedit: intertwining is bad

You’re not supposed to route it exactly the depth of the plate. You’re supposed to do the math. You should measure the shaft length from the top of the mounting plate to the button of the balltop. You subtract 23 or 24mm (whichever amount you want to show) and that’s how deep your recess + plexi + mounting plate thickness should be. For example if the shaft is 34mm (just making up a number), the mounting plate is 3mm, and your plexi is 3mm, then you would want 34mm - 24mm = 10mm (total recess + thickness of plexi + thickness of plate). 10mm - 3mm (thickness of plexi) - 3mm (thickness of mounting plate) = 4mm (total recess).

Per told me to do the double springs before, but I didn’t like the feel personally. I tried both on top and intertwined.

The diameters aren’t very different. You can’t put one completely inside the other.

So then how do you install the springs?

Thanks for your reply Paik. What you stated is exactly what I did, but now that I think of it I wonder if I have one of those JLW’s that have the longer shaft. Based on the diagram from the Sanwa catalog, the shaft should be 27mm from the top of the mounting plate to the button of the ball top. If I route 3mm deep in to my wood, then that should leave me with 23-24mm of shaft. My only problem is that I never bothered to measure the shaft of the stick once I received it, I just figured that the measurements were the same, but I guess they aren’t. My shaft is measuring over 1.25" (from the top of the mounting plate to the button of the ball top), which is way longer than 27mm.

Edit… I think this is what I have :d:. I don’t think it was a bad diagram or my fault after all. I just have the stick with the longer shaft…crap! If it doesn’t affect it’s performance though I’m not sure if I should get a different version (routing deeper in to the wood isn’t an option) or just leave it…decisions, decisions.
