I didn&#8217;t like the state they were in when I got them and have been putting off fixing them up for the last few years since I bought them. But I recently acquired a pair of used top bits (the plastic top bit with the old Seimitsu logo) and decided to see if I can make the joystick itself any better.<\/p>\n<p><strong>The biggest flaw<\/strong> of the LS-30 in my opinion is that the throw is too long and it feels kinda &#8221;mushy&#8221;. This might be because I got my pair used, but I \u00a0remember this feeling from back when I was playing Heavy Barrel in the arcades in the 80&#8217;s, so maybe the compromise to get the rotary function working came with the price of the 8-way function of the stick taking the back seat.<\/p>\n<p><strong>First off<\/strong>, I wanted to compare the bits the joystick is built from with less rare joystick models, and I have a couple of spare bits that seemed to fit the bill. I had a Seimitsu LS-32 (not used any bits for my mod, but comparisons are below), some SANWA JLF parts (the metal washer is used, the shaft cover I didn&#8217;t use) and an Ultimarc Ultimate 360 Hard Spring that I picked up along with a SUZO 500 as I was curios if the spring would be of use in an arcade joystick. Seems I was right, as it&#8217;s very close in feel to the LS-30 spring (that&#8217;s actually even tougher, rivally the SUZO 500 spring). I did try some of the other springs I have here, like the LS-33, JLF and LS-32 one&#8217;s, but this had the perfect width and height also.<\/p>\n<p>I also tried to fit the same type of microswitch used in LS-32 (I had brand new spares) but it was too loose compared to the ones fitted in my LS-30 (Matsushita brand if I recall correctly). I might pick up some SAIA BURGESS ones again with blades next time I order from Arcadeshop.de as they are the best blade fitted microswitches I&#8217;ve tried so far.<\/p>\n<p>Yesterday, someone posted @ ArcadeOtaku that the<strong> LS-32 plates will fit the LS-30<\/strong> (so that I can mount these with little to no hassle), with this in mind, I finally got one of these out of my storage and got to work making them decent.<\/p>\n<div id=\"attachment_993\" style=\"width: 580px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/ls_comparison.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-993\" class=\"size-full wp-image-993\" title=\"LS-30 &amp; LS-32 plastic bit comparison\" src=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/ls_comparison.jpg\" alt=\"\" width=\"580\" height=\"261\" srcset=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/ls_comparison.jpg 580w, https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/ls_comparison-300x135.jpg 300w\" sizes=\"(max-width: 580px) 100vw, 580px\" \/><\/a><p id=\"caption-attachment-993\" class=\"wp-caption-text\">LS-30 &amp; LS-32 plastic bit comparison<\/p><\/div>\n<div id=\"attachment_994\" style=\"width: 580px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/ls_comparison_2.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-994\" class=\"size-full wp-image-994\" title=\"LS-30 &amp; LS-32 plastic bit comparison 2\" src=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/ls_comparison_2.jpg\" alt=\"comparison_2\" width=\"580\" height=\"580\" srcset=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/ls_comparison_2.jpg 580w, https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/ls_comparison_2-150x150.jpg 150w, https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/ls_comparison_2-300x300.jpg 300w\" sizes=\"(max-width: 580px) 100vw, 580px\" \/><\/a><p id=\"caption-attachment-994\" class=\"wp-caption-text\">LS-30 &amp; LS-32 plastic bit comparison 2<\/p><\/div>\n<div id=\"attachment_995\" style=\"width: 580px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/spring_comparison.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-995\" class=\"size-full wp-image-995\" title=\"Spring comparison\" src=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/spring_comparison.jpg\" alt=\"spring_comparison\" width=\"580\" height=\"268\" srcset=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/spring_comparison.jpg 580w, https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/spring_comparison-300x138.jpg 300w\" sizes=\"(max-width: 580px) 100vw, 580px\" \/><\/a><p id=\"caption-attachment-995\" class=\"wp-caption-text\">Spring comparison - LS-30 and Ultimarc Ultimate360 &quot;hard spring&quot;<\/p><\/div>\n<div id=\"attachment_996\" style=\"width: 580px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/shaft_comparison.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-996\" class=\"size-full wp-image-996\" title=\"Shaft comparison\" src=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/shaft_comparison.jpg\" alt=\"\" width=\"580\" height=\"285\" srcset=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/shaft_comparison.jpg 580w, https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/shaft_comparison-300x147.jpg 300w\" sizes=\"(max-width: 580px) 100vw, 580px\" \/><\/a><p id=\"caption-attachment-996\" class=\"wp-caption-text\">Shaft cover comparison<\/p><\/div>\n<p>I didn&#8217;t have a drill at hand to make the SANWA JLF shaft cover fit the LS-30 shaft, but the outer diameter is spot on, so I might get a drill so I can use these. The taller JLF cover will compact the spring a bit more, but I don&#8217;t think it will be an issue as the spring still has some space to move about.<\/p>\n<p><strong>Putting the stick together again<\/strong> after pulling it apart involved lots of trial and error, especially as I was trying out lots of different parts from the LS-32 (nothing really worked well) but I finally got a result that feels really good. The spring was getting stuck a lot and the centering wasn&#8217;t consistent, so I tried lots of washers until it struck me that I did have some JLF parts. The JLF metal washer fit perfectly under the microswitches, stopping the shaft cover from going through the hole.<\/p>\n<div id=\"attachment_997\" style=\"width: 580px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/washer_mod.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-997\" class=\"size-full wp-image-997\" title=\"SANWA JLF metal washer\" src=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/washer_mod.jpg\" alt=\"jlf_washer\" width=\"580\" height=\"310\" srcset=\"https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/washer_mod.jpg 580w, https:\/\/emphatic.se\/wp-content\/uploads\/2012\/01\/washer_mod-300x160.jpg 300w\" sizes=\"(max-width: 580px) 100vw, 580px\" \/><\/a><p id=\"caption-attachment-997\" class=\"wp-caption-text\">SANWA JLF metal washer<\/p><\/div>\n<p>I installed everything in this order:<\/p>\n<p>1.
