« Part 1: Identification, Historical Evidence and a Vivid Imagination Part 2 of The Restoration of a 14" Tenon Saw series Part 3: Restoring the Saw Handle »

This saw plate is remarkably well preserved for its age, but it could benefit from a clean. I gathered the stuff I thought I might need, but all I used was the 3-IN-ONE degreaser foam, the Hammerite Rust Removal Gel, the green scouring pad, kitchen roll, and wet and dry paper (more than you see in the picture below).

I start by spraying the plate with the degreaser. I have found that the rust remover works better on the first application if the surface has been degreased first.

Wait 5 minutes…

Wipe the surface with kitchen roll. Then repeat for the other side.

Apply the Hammerite Rust Removal gel liberally.

After 20 minutes I dip the green scouring pad in water…

…and gently rub along the length of the plate. The black staining and any rust comes off in no time at all.

Then I washed the surface with a paper towel dipped in clean water and repeated the process on the other side of the saw plate.

With the rust and grime removed, it was time to start polishing the plate with wet & dry paper used dry. I went through the grits using long strokes along the plate. The grits used were P120, P180, P240, P320, P400, P600 and finally P800. I used a wooden block with the P120 and P180 grits. The other grits were used without the block. This was the result.

I like a shiny saw plate on my back saws. I use the reflection in the plate to line up my saw cuts so that I know when I’m cutting at 90 degrees and 45 degrees without having to mark the wood.

I might polish this a little bit more, but my arms were aching so I called it a day for the time being.

In Part 3, I turn my attention to the saw handle.

Thanks for watching.

Very impressive restoration. I’ve never expected to see a saw that was reflective.

Andy. should you ever feel the need to come to the states you can swing by my place and help my make some of my tools as shiny as yours.

I own a B&B so I could probably make it worth your while.

Thanks for all the compliments guys. My arms and shoulder are killing me today after all that rubbing. This saw needed a lot of work on the back side because there were two areas that were lower than the rest of the plate. I had to effectively take the rest of the plate down to that level whilst keeping it flat and an even thickness. You can just see the areas in question in the following photo. There’s a name for this phenomenum, but it escapes me now.

Ryan – That’s a tempting offer, if I ever escape from Denmark. :-)

That is really first-rate work. I will have to figure out what a North American match for the Hammerite is, but the degreaser is a very good idea.

Escape from Denmark? Laugh.
Andy you are the master! I am always impressed to see what results you come up with, it is probably more shiny than when it was sold out the maker a long time ago.
What really bothers me is to see how much more effective the rust remover is at your place… It might be the degrease phase, since for me it is much more pitted and uneven after this remover.
Glad to see you are working on that sexy bench of yours again, but a little sad that you have upgrated the surface now… perhaps you could follow one of the cuttingboard blogs and make a really sexy top! Smiles.
Andy yóu are the master of rust removal, no doubt! Impressive work you have done.
Best thoughts,
Mads

Mads – It can’t be more pitted afterwards, its only rust remover and I take you mean uneven in colour, not that the surface is uneven. Next time I visit, bring out your worst rust and I’ll give you a demo.

By the way, good idea to upgrade the workmate top with a cutting board. I’ll get to work on my Sketchup design. It shouldn’t take more than a week to come up with something. I think I need some dark wood and some light wood. I’ll cut up both pieces then glue them back together in a different order. Tricky, but I think my skills are up to it now. ;-)

If anyone other than Mads is reading this, the previous paragraph is a private joke between me and Mads. Don’t ask.
