Step 6 – Assemble your Super Drill

Once the magnets are dry and solid push the armature back into the can, carefully lining up the fan so that it slides into place (watch you do not jamb your hands – the magnets will grab at the armature).  Use a flat blade screwdriver to gently push the fan fully into place on the armature, so that it doesn’t rub on the brush housing.

Seal the front plate on, either by using an old chisel to hammer open the slits and squeeze them tight again, or use a few dabs of JB Weld or similar heat resistant glue.

That done, carefully put the brushes back into position and, test the motor with a gentle bit of throttle.

It should work fine. Now reassemble your new Super Drill and have some fun.

I have found it to work extremely well, with somewhat scary amounts of torque!

I have done this with a whole bunch of Bosch 24 volt battery drills now, as the broken ones are relatively cheap to pick up on e-bay.

    I’ve been using a super drill that Bongo modded for me after I picked up a couple cheap on ebay. Over the last couple of months its drilled upto 12mm masonary, mild steel to 8mm and wood of various type with a range of bits flat headed and fostner up to 26mm. The only thing stopping me trying larger holes has been my collection of drill bits. Yesturday i was using it for a 100mm hole saw to cut through the roof of the house and was reminded how strong it is when the hole saw caught and the drill spun my hand against the wall, jaming the trigger on. 2 seconds later smoke and a lot of heat. On dissambly the magnets are fine but the armature has blackened wiring, shouldn’t be to hard to replace.
    With a after market 3.0 amp battery i’ve been enjoying excellet battery life, eg this weekend lifted and replace a rooms worth of floor boards, the afore mentioned hole saw cut, construction of a desk and deconstruction of several packing cases and the drill/battery showed so signs of loosing charge until the ‘incident’.

    Super drill lives again, no damage apart from the burnt out armature

    I got around the problem of fitting the fan off the new armature with the magnets already in place by carefully cutting opposing fan blades down, allowing them to pass the magnets and remain balanced in use.

    Yeeha. Good news!

    About time I updated on superdrill usage. I’m currently working on a shed to free the dining room of spades and lawnmowers. This is providing a excellent drilling and screwing task for the superdrill.

    I recently had a score on ebay and picked up 4 professional grade 24V drills, one works fine straight out the box. I’ve since got another working by switching bushes round.

    Side by side comparison of the prof grade and the super drill using 8mm auger drill bit through 200mm of wood showed that the super drill definatly has a little more torque. Screwing into the softwood joisty material the prof grade was more satisfying due to the more controlable clutch. Both drills have had a busy day and haven’t required charging.

    All in all the superdrill has proven itself to be excellent over the last 2 years of house and garden modification. Its lighter in the hand than the professional grade and as long as the reason for that lightness holds up (plastic rather than metal housing) it will be my first choice drill for drilling due to the high torque. The real bonus for me today has been the ability to drill, countersink and screw using three drills and not have to faff about.

    Ah ha! 3 Drills, now that’s some goodness! And a nice comparison, between the professional and the green super. Good work!
