==Bearing (coixinets, rodaments)==&lt;br /&gt;
Són els coixinets dels patinets. Se'n necessiten 3*2*4=24 unitats. El diàmetre interior és de 5/16'', i aleshores les arandeles poden ser de 6716''. Aquests són els coixinets que es necessiten per fer les guies.&lt;br /&gt;

==Ajuntar 2 peces de DM de 1,9mm==&lt;br /&gt;
Faig servir les broques de fusta de 6 mm i 12 mm. Els cargols que faig servir són els de 60mm x 6mm diam. El forat de 12mm el faig a 35mm del cantó, i la profunditat a què s'ha de fer és que la punta de la broca quedi 1-2mm per sobre de la peça.&lt;br /&gt;
&lt;br /&gt;
Broca de 6mm: com que el gruix del DM és de 19mm, la meitat és 9,5mm&lt;/div&gt;</summary>
