That blade is looking so shiny!
I may have to work out a strategy for my leaf springs. ( I have just had a thought will Simplicity's "Body" be wearing an L-Spring?). I may have to enlist some help as going back to clean metal with W & D is an awful lot of rubbing. My thick blades are nearly 10mm and will have to reduce to 9mm to end up with clean metal.

Angle grinder could remove a fair bit of metal quite rapidly. With a little practice you can do very accurate work that way. I know knifemakers who use that technique to make very good knives.
If you have a belt sander you might be able to get the right sized metal-grinding belt to fit on it. It would not work as well as a proper metal belt grinder as the speed will be too slow but it would work up to a point.I'm doing my May Challenge - I may or may not give a #*c&

Please explain: just me being economical with words ... up through the grits
I started at 60 and the above is 80. I have 120 next in the green Zirconia set, man those things are sharp if you touch them when running
I have 120, 240, 600, 1000 on the way in Aluminum Oxide
All that is on the cheap belt/disc machine and no hotter than me fingers can tolerate.
Once I hit 1000 a bit of time at 1600 wet and dry should see a finished shine, a can get out as far as 4000 but even 1600 will be tedious
Cheers
Phil

Mines on the "im a cheapskate" ryobi belt/disk bench sander, the zirconia belts have made a big difference to the material removed
The angle grinder with even the finer grades of flap disks can end up taking a big bite and leaving grooves that are just too deep.... good for doing the radius corners though
Cheers

I've walked past the blade to many times and decided to spend some time standing at the sander, about half way with 600, had to jump from 240 to 600... really want a 400 grit belt
For anyone that missed it, that is from a large left spring and it's all been milled and sanded without any heat treatment to make it easier.... it's been interesting.

Body and blade, really need to marry these two together, brought the blade in to measure up and design the 3D printed insert.
small progress but at least it's something

So does that mean that you will cut a relatively simple cavity in the body to accept the insert which will then hold the blade?

Measure once and.... the phone rings!
