Triton Circular Saw Refurbishment E3

On inspection, I found a couple of issues to deal with.

  • Rust spots on the blade
  • A stiff armature bearing
  • A stiff and sticking trigger

The rust spots were easy to resolve. I coated them liberally in my non toxic rust remover gel, covered the whole blade in cling film and left it alone for a while…


After a while, I scrubbed it with wire wool using the gel itself as a lubricant. This got rid of most of the rust but it needed another application to make sure. This had the added bonus of completely cleaning the resin off the teeth; something worth bearing in mind. This was when I found the two missing teeth. I’ve no idea when this happened, but I must have made loads of cuts completely unaware they were missing, so it obviously has no effect on the quality of the cut. Blades can be replaced, though.

This is the outer bearing on the armature…

The contraption is just to hold it upright. It wouldn’t spin freely. The cure? A few drops of oil. This also cured the sticky trigger.

The bearing housings were full of grease impregnated with dust…

…so I cleaned them and the rest of the casings with GUNK…

The result…

No evidence of damage or wear. As far as the motor armature and the coils was concerned, I cleaned those with brushes and a hoover; no water or cleaning fluid got near them.

Assembly

First the brush loops were slipped back over their contacts, the coils slid back in and the wiring relaid as it was…

This is where detail photography comes in; to refer back to. Reconnecting and repacking the trigger assembly…

With the handle cover back on and the black plastic spacer in place, the armature simply drops in…

With the bearing and gear greased and the armature lock put in place, the blade housing can be dropped on…

In that last photo you can see that the lock spring has to go into the housing in a certain way. That was fiddly. The two halves secured together again…

With greasing as you go, the reduction gear was refitted…

Next the blade guard was refitted, taking care with the shims once again, not to mention the spring …

Next, final assembly…

…which was quite straightforward, making good use of the multitude of pictures.

The completed saw…

I was worried by that erstwhile sticky trigger, but when I plugged it in, it worked ! Phew.

Triton Router Refurbishment E3

Episode 3

To get the base off, there are two pins holding it to the slider tubes which have to be knocked out…

Using drill bits as drifts is quite useful because one can choose exactly the right diameter. This is important: obviously too large and it won’t fit in the hole, but too small and it can jam. A good snug fit is best. Drill bits are cheap and consumable. This is the baseless router…

As you can see, the closest tube slides right out, but the further one is held by cogs so will have to wait. The smaller tube is the depth stop rod (height stop rod? Och, who cares)

Of course, as I’m doing this, I’ve no idea for sure how it’s all held together, or whether my taking it apart will damage anything. So I’m relying on three principles:

  1. I’m prepared to bin it if I break it beyond repair
  2. Surely it’s made for ease of assembly at the factory and for ease of repair in the field?
  3. Wish I could think of a third one…

To take the body apart, it seemed obvious – for no good reason – to start at the top section.

I removed the black top cap…

In the first picture, I’m holding the wee screw to the big one to show that it’s the big one that goes in the black cap. This is because they’re all going into the same cleaning pot. Next I removed the switch panel on the side…

The spring  is for the depth stop rod, which is in shadow middle right, and which can now be slid out.

Lifting the speed controller off the armature end…

…showed that it – the armature end – wasn’t secured; I mean by a bolt or screw or anything. Would the armature slide right out, then? Undoing these screws…

…allowed me to prise the two halves apart…

Start gently. As soon as you feel some give, you know your on the right track. Take your time though, inspecting as you go along, being wary of things suddenly pinging out. Small bits – springs etc – can be lost that way. There is a plastic cylinder in the base which simply pulled out…

Almost ready to begin cleaning…
