Easy enough to buy a new switch for cheap from AliExpress.
The position and protection being under the saw is a flawless design, or has been for me since I bought the saw used at least 20 or more years ago.
I've been buying the silver contact model switches in a fair few different configurations from there for my projects, only a few dollars more per switch at the end of the day.

After so many years away for the forum because of life, it's good to see a familiar name posting up.
I wish we where all close by to each other to visit each other and talk shop, I've missed the good old days of this forum.

You have to get in the line please.
I suspect it is a very long line and I am probably near the head of it.
Its time for one of our enterprising chaps to knock out another series of those a Round Toit medallions.
My wife will likely order a half a dozen and pin them on someone.
Having said that I am going to the shed to search for the brush assembly.
Cheers

I found the brush assmbly but don't know how. Advice to anyone in particular. Do not piz off the tidy up fairy.-
I must have upset her badly and shes left for parts unknown.
Anyhoo here is the assembly.
I remember now, it was an imperial 1/4" shank so had to replace the 6mm bore bearings I had bought.
The housing was a piece of 19 x 19 CRS steel about 25mm long. Recessed the faces for each of of the bearings and held the protruding shank with a grub screwed collar.
Simples!
Need to replace those bearings as I think the coolant water and gunge have made them harder than it should be to rotate by hand.

Why is it the most used machine in the shop gets neglected, lol.
I've spent countless hours upgrading and cleaning up the mill with powered quill feed, 5 axis DRO, raising blocks, combined quill locks, power feeds VFDs lights, new electrical box, etc etc
Same with the lathe adding raising frame, a telescopic leadscrew taper attachment, extended splashback, lights, 4 axis dro etc
I bought a 7x12 bandsaw for $150 about 9 years ago and even it has been completely rebuilt.
And here is my pore old humble 100x115mm bandsaw that I bought used has only got a bodgey coolant system 15+ years ago, lol
It's just so reliable, every 6-12 months (usually 2 blades) it gets a full pressure wash, oiled then strait back into service.

I wired in the coolant pump at the motor terminals today. no room for a switch to mount on the terminal cover, like dave did.
Think I'll seach for an inline switch and use that. Don't like the idea of running the pump with the line closed off, if I even need to not run it...lol
Googled chip brushes....Would like a rotating (self cleaning?) brush but didn't find any around 25mm in dia. Will look at brush 'tooth brush' type.
I assume it should mount under the blade, so have to see how much room I have.
This chap has done a nice job.
Steve

Hi Steve, Guys,
Dremal do a small wire brush but its a bit thin and only a small shaft, I think that you would need two of them to do the same job cleaning the bandsaw blade.Best Regards:
