Triton TPT125 Thicknesser Cutting Blades Change

In this quick Instructable I will show you how I changed the blades on my Triton TPT125 Thicknesser, I've had this for a couple of years now and Inevitably using a lot of pallet and recycled wood there has been times when nails or staples have been hidden beneath the surface of the wood or not seen and consequently the blades have ended up with notches, and this makes for uneven finishes on the stock and a lot of sanding.

I didn't realise until a friend said that the blades are reversible which is great news, so with that said I thought I would have a go at changing the blades myself.

As always with a task like this there are risks Involved.

The 2 main risks are ensuring the Power lead is disconnected from the supply and the other is that the blades are sharp and should be handled with care.

There are Instructions on the back of the Thicknesser for this process.

The Process:

Prior to starting this process, ensure the Thicknesser is unplugged from the Power Supply.

I Vacuumed the Thicknesser as well before commencing.

The Triton TPT125 Thicknesser has 2 blades which in this case are reversible, the tools to do the blade change come with the Thicknesser, there is an Allen Wrench and 2 Magnets to lift the blade off the mounting pegs.

The first Job will be to remove the Dust Extraction Cover, this is secured with 2 Allen Head Bolts, notice that these Screws are different to the Blade cover screws, put the cover and screws to one side.

The next job is to remove the blade cover, this is secured with 2 Allen Head Bolts and Washers, put the cover and screws to one side.

Being very careful and wear safety gloves for this, turn the drum until one of the blades is accessible, this will click and lock the drum when in the correct position for blade removal.

For the GIB removal I used a T-Bar Allen wrench, the wrench that comes with the thicknesser flexed too much.

Using the T-Bar Allen Wrench to Unscrew the 6 Allen head Bolts which hold the GIB in place, put the GIB and Bolts to one side, removing the GIB reveals the blade which is sited on 3 locating pins.

The process to remove and turn the blade is made very simple by using the 2 magnets which come with the thicknesser first to remove the blade then rotate it and re site it on the locator pins, I ensured the GIB was clean before refitting, then the 6 Allen Bolts are refitted, screwing the bolts in finger tight then tightening with the T-Bar Allen Wrench, that's one blade sorted now to the next one.

To reveal the 2nd Blade, look to the left of the machine and there is a small red lever, pushing this forward allows the drum to rotate freely, and using safety gloves, rotate until the 2nd blade is visible releasing the lever the drum will lock in position so the blade can be removed using the same process as the first blade.

Re-assembly:

The blade cover is the first component to be refitted, ensure this is clean prior to fitting and using the 2 Allen head bolts with washers secure in position.

Next up is the dust extraction cover, reposition and refit the 2 Allen Head Bolts and that's it, Job done.

At this point I will order a pair of new blades, they are around £16/$19 for the pair which isn't too bad.

My dust extraction set up for the Thicknesser is a self designed Vacuum adapter, I use a cylinder Vacuum which has a 39mm hose, the Dust Extraction outlet is tapered so my Fusion 360 designed Vacuum adapter caters for this and the Vacuum hose is a push fit into the adapter, the hose is threaded and it's left hand so pushing the hose in and slightly twisting to the left ensures it's a snug fit, I will add the STL file for anyone who has the same set up, The adapter is also embossed with Triton Thicknesser.

That concludes this quick Instructable, Thanks for looking.
