| A bushing is a small cilynder, usually made out of some form of steel. For balisongs, some form of stainless steel is the standard.
| |
|
| |
|
| ==Bushing systems==
| |
|
| |
| Bushings for balisongs usually come in one of two types: "traditional" bushing system, or "floating" bushing system.
| |
|
| |
| ===Traditional===
| |
|
| |
| The traditional bushing system is by far the most popular pivot system. So much so that people often refer to traditional bushing system, as just "bushing".<br>
| |
| In a traditional bushing system, the bushing goes inside the [[blade]] and gets sandwiched by two [[washer|washers]] on each side. It is generally agreed that the Traditional bushing system is the superior one.
| |
|
| |
| ===Floating===
| |
|
| |
|
| |
|
| |
| ==Sizes ==
| |
|
| |
| Bushings have 3 measurements: [[Outer_Diameter|outer diameter]], [[Inner_Diameter|inner diameter]], and [[Height|height]].
| |
|
| |
| ===Inner Diameter===
| |
| Often abbreviated to ID.<br>
| |
| The ID of most bushings will usually be the same, around 4.7mm-4.9mm (0.188in)
| |
|
| |
| ===Outer Diameter===
| |
| Often abbreviated to OD.<br>
| |
| Unfortunately there is no standard for bushing sizes. Some balisongs may use the same bushing size, but this is not guaranteed. For example:<br>
| |
| [[Bladerunners_Systems|Bladerunners Systems]] uses 6.35mm-6.36mm for their [[Bladerunners_Systems_Replicant|Replicant]]<br>
| |
| [[Nabalis]] uses 6.985mm for their [[Nabalis_Vulp|Vulp]]<br>
| |
| [[Baliplus]] uses 7.052mm for their [[Baliplus_Titanium_Barebones|Titanium Barebones]] clone.<br>
| |
| [[Squid_Industries|Squid Industries]] uses 6.326 for their [[Squid_Industries_Nautilus|Nautilus]]<br>
| |
| To see a list of which balisongs use which type of bushing, check out the [[Balisong_list|balisong list]].<br>
| |
|
| |
| While some of those differences may looks small (for example: 6.985 vs 7.052), they can still dictate whether a bushing might or might not fit inside the bushing hole of a [[blade]]. You can use a small bushing for a larger bushing hole (for example 6.985 inside a blade that needs 7.052) but that will introduce problems. Please read [[Tune#Handles_move_up_and_down]]
| |
|
| |
| ===Height===
| |
|
| |
| The last axis of the bushing is the height. It is the only flat part of the bushing. There is no real standard in bushing height since every [[blade]] will have a different thickness.
| |
|
| |
| ==Tuning==
| |
|
| |
| For an explanation on what tuning is and how it impacts the performance of a balisong, please read the [[Tune|tune]] article.
| |
|
| |
| ===Tuning traditional bushings===
| |
|
| |
| In order to have a decent tune, you need to sand the [[#3.3 Height|flat part of the bushing]] so that it is only slightly higher than the blade. If your bushing is 0.025mm (0.001in) shorter than your [[blade]], you have an undersized bushing and your balisong will most likely [[bind]]. You must also be careful to not sand your bushing at an angle because this will make your balisong bind, but only in specific handle positions. Some community members tend to call uneven bushings "lopsided". To counteract uneven bushings, makers have created tools to help mitigate this problem. [[Nabalis]] has created the [[Bushing_Buddy|Bushing Buddy]] and [[Knife_Dogs|Knife Dogs]] have created the [[Pivot_Lap|Pivot Lap]].

| |
| ===Tuning floating bushings===
| |
|
| |
|
| |
|
| |
| ==Conversion==
| |
|
| |
| It is possible to convert different types of bushing systems.
| |
|
| |
| ===Floating -> Traditional===
| |
|
| |
| A floating bushing system can be converted to a traditional bushing system.
| |
| Currently the instructions are missing on how to do this, but a [[Community_Members|community member]] called [https://www.youtube.com/@taktyc/videos Taktyc] has created a [https://www.youtube.com/watch?v=J08_tFzMsrM video] in which he announced that he will make a tutorial about this.
