Thread: Rusty Jointer

Try Lanolin, its good for scaly leg on poultry too!

How rusty is it?

Surface bloom you can treat with phosphoric acid (Rust Dissolver at Repco); this converts the iron oxide into something else that's black.

And/or go over the table carefully with a ROS and fine abrasive.

Thanks for the replies guys. The bed is just surface rust from what I can see. Just one further question, would sand blasting damage the machine, and would I have to strip it right down afterwards to clean it out. The reason I ask is that I may be able to get that done at work for free or next to, just depends on who I ask.

I used a fine wire brush on my grinder. Electrons can save too much exertion.

Or a 3M paint stripper wheel in an electric drill - they're brown and about 30mm thick.

I'd be wary of sand-blasting for the same reason that care is needed with a ROS - you don't want to compromise the flatness of the table.

Steel wool and elbow grease will work wonders to clean up modest surface rust, 600 grit W&D paper used dry with a chipboard backer block, followed by 1200 grit and steel wool, for more heavily coated surfaces. Do full surface equally to ensure that you retain flatness.

A good of fish oil and let it soak in will help.

A largish sheet of glass with a handle siliconed to it will make a nice backing block for wet'n'dry - the bigger it is, the flatter you'll get it

Thanks for all the tips guys. The winner was the angle grinder with a wire wheel. The bed and fence have both come up rather nicely thank you very much. A little bit of hard graft and the in-feed bed raises and lowers nicely as well. Picked up a 1 1/2 hp single phase motor today for a whopping $80, and will be picking up a 3 inch pulley tomorrow morning for about $15. Original 3 phase motor was 1hp, 2300 rpm with a 3 1/2 inch wheel, new motor is 2850. Will give an increase in cuts per minute of 1500 (24150 vs 25650). Intend to give the beast a paint job, and need to by a belt and build a stand, so total outlay should be about $200 for a 150 x 895 jointer which makes both me and SWMBO pretty happy.
