Purposely did that so i get more playtime. lol!
My own Technics tips:
1) That
brick separator is pretty much useless for studless. It's more for the standard lego studs sets.
2) To Push : Phillips screwdriver (test-pen). Either original Phillips, Stanley, or RM2 from pasar malam. This is mainly used to "push" those
axles at the head/tail portion. I feel this is just a nice size and grip, with more than enough force. Hold the tip close to fingers, find your own rhythm, strength, and style. Much easier and stronger force than the puny brick separator. No scratch.
3) To Pull :
(i) Thin rubber grips. Any kind 10cm is enough. I use extras from my badminton
overgrip.
This is the same grip I use to open those 1.5L carbonated drinks container. Sometimes it's pressurised so hard in order to open it.
(ii) Pliers : That's right. Wrap the item with thin rubber grip (1 or 2 layer), use plier to grip and pull. This can be done on any axle, but you must know how to grip using the plier to minimize damage. Assume the pliers grip top and bottom, you must grip X, not +.
X gives you 4x points of contact. + gives you only 2x points of contact.
Pliers must grip using the front teeth, not sideways.
For pins, it's easier to damage, unless you practise well with axles first.
Also, must not use pliers excessive force to grip and pull. Just enough inner force.
I did damaged a few pins and dented a few axles when starting. Now, I'm
confident experienced when to use it without any damage/scratch/dent.
4) Push & Pull technique : basically combination of both #2 and #3 above. Sometimes you just can't push the entire axle out. So, push out quarter/half first. Then use the pull technique.
5) Pin : another pain in the
sss finger.
This one is easy, treat it as axle to push out.
The rest, just use the pull technique with thin rubber grip.
Edit: which part to grip ... the pin normally look like this from head/tail:
( )
grip both the top and bottom.
Don't grip left and right, the pin will damage easier.There is a technique where you need a brick/liftarm with this "
Utensil Space Gun / Torch ?" , so you plug the other side of pin-hole to "stop" it, and pull it out first. Then release this stopper by pulling out the pin. Then use pull technique above.
Don't know how to explain, I think there is some sort of video or other blogs/explanation on this. Some older technics manual has this as well.
Anyone who has tried dismantle 8110 front wheel hub-set will know the difficulty of the axle-2 (red)
6) Do not use pliers/test-pen as leverage or to skewer something. Metal vs plastic = metal wins. Use the useless brick separator as leverage.
