Open & GT car prep for newbies

As much notes for myself as a couple of tips for the newbie assemblers of Slot.it pod type chassis - recommended is 0.75mm SW pod but 1.00mm will also do, provided the magnets ever so slightly recessed (only by feel):

A useful kit complete with 61 smaller cut off wheels for motor pod.

Illustrating the plastic swarf build up on the small cut off disks, change regularly and typically six per pod project for clean accurate cutting. The smaller disks allow access to the inside rear.

Needle file roughening edge of magnet. The process relies on support for both front and rear long sides of the magnet, for the front and rear location.


Warm the tubes in just boiled hot kettle water, mix and paint on to the nylon before fitting magnet which should be only just below (by feel only) the edge of the plastic (NEVER ABOVE). Keep the tubes stored vertically in a similar container [Oliver tip] thereafter. Once happy with location and the glue dried a bit, reinforce with a couple drops super glue from top (inside).


Rough cut the front slot and finish with a needle file so the magnet clips in tightly for maximum support of the magnet. Use two stacked of the Professor 27x5x1.5 magnets at the rear and one 25x6x1.5 (any up to max two mm thick like Slot.it 25x8x2) at the front. The maximum downforce is to be biased to the rear. Again only just inside surface by feel. Note front magnet position has proven important and whilst the Slot.it magnet holders remain, do not use them (creates edge of the cliff downforce, not good). Rather stack trimmers on existing magnets.


The fitted magnets with Black Wonda Fix (only use black never the clear) around the edges, both reinforced with a drop or to two super glue from the inside.


Trimmer magnets added, a must at the back and a Slot.it magnet has proved an ideal trimmer at the front, in the past.



VERY IMPORTANT - reinforce the front axle supports with black Wonda fix at fore and aft of the axle supports (zoom pic if battling to see). Fit the motor pod and tighten the screws just enough to allow the pod to slip fore and aft about 1 mm travel (also important, do not lock up the pod).

The rest of the story will follow in due course ;-)
