Blueprinting Slot Car Motors
Slot 1 is a successor to Socket 8. Apply paraffin or turpentine as lubricant with a brush and turn at 2, RPM, taking very light cuts until the commutator cleans up. Our completed spaced, bound, soldered, balanced, and trued armature.
Run the commutator end in a guide tube a piece of 5mm brass rod reamed to 2. Step 13 — Skim the Commutator When the commutator was made it was probably diamond turned by some inscrutable oriental gentleman in a factory in Wanking.
This is not as easy as it sounds — you need special tooling to keep everything lined up and to prevent the shafts from buckling. If you need to remove more, drill a third hole in between the existing two.
Hit on the anvil heavy side up — never on the blades.
Allow the armature to roll push it slightly — if it has a heavy side it will always stop in the same position. Many of these latter devices are equipped with own voltage regulator modules, in order to supply the new CPU with a lower core voltage, which the motherboard would not otherwise allow.
If you drill too deep the core may break out at high revs. Remove material in very small quantities, checking frequently. Slot 1 also obsoleted the old Socket 7at least regarding Intel, as the standard platform for the home-user.
If you are simply checking an old armature that you know for a fact was balanced but is now out of balance — particularly if it is severely out of balance, then the armature shaft is bent. It was designed for lower-priced Celeron CPUs.
The Celeron does not have official SMP support. Having said that the web holds many plans for home built rigs so it is possible. It can be replaced by pushing out the old shaft with a new one use a 2. These are good for loading gels and making microarrays v slot assembly glass slides. Unfortunately after all the slings and arrows of assembly and errors in the shaft and assembly process, etc.
The above PSB arm was damaged by failing to lubricate the rear bush — after shaft replacement and slot utilization comm skim it was as good as new. If you found the comm easy to move you can add a dab of superglue to the back of the comm before binding and lacquering.
Skimming the comm generally does not upset the balance unless you removed a stupidly large piece of solder in the process — so you might just want to return it to the balancing rig for a final test. This form lacks a case entirely, consisting solely of the printed-circuit board holding the components.
Keep this tool only for skimming commutators. The front consists of a black anodized aluminum plate, which is used to hold the CPU cooler. We have by now also got solder onto the running surface so all in all we need to give it a skim to restore it to true. If in doubt check the run out with a dial gauge.
You start with both short and long anti-buckling spacers in — when it dead-lengths remove the short one, when it dead-lengths again swap the long one with the short one and finally after it dead-lengths again remove the short one and complete the assembly.
