Hi,

Still in the studying phase for a PRO48xx.

I'd like to know if any of you guys (or girls ???) had any problem with rust on the "racks" and the "cold rolled guide bars" on your machine.

Aluminum should'nt be a problem I guess and every other steel part in the kits are painted (red) steel.

But the "racks" and the "cold rolled bars" are exposed steel.

I've asked Cory about this and he told me that they use WD-40 to protect the bare metal.

What do you use ? (If any...)

I could paint the rack and guide, but I guess painting the teeth on the rack ain't a good idea (anyway it would'nt stay very long...) and similair for the guides (the place where the bearing rolls would be return to bare steel in no time).

Please share your thaughts.

Thanks!

AJ

The teeth on the racks should have grease on them. A lot of people paint the other surfaces of the rack.

As for the rails, there are products like this that will prevent rust.
Bostik 10220 Aerosol Top-Cote - Power Tool Lubricants - Amazon.com (http://www.amazon.com/Bostik-10220-Aerosol-Top-Cote/dp/B0000223UD)

I use it on my table saw and it's been rust free for 20 years.

i've had my pro4848 less then a year, but i don't have any signs of rust, i haven't done anything to protect them, but reading this thread is making me think maybe i should do something...

Was just going to spray wd-40 on mine. It's been cold here in Cali and I opened up a drawer yesterday to find my sockets were sweating so I guess I should do it soon.

Was thinking about masking off the top parts of the vrails and painting them.

i can't say for sure, since i have not tried, but i don't think you could paint the v-rail on the pro machines and then install it and not scrape off some of the paint. maybe you would be OK with that, but i think it would look rough right away. when i installed the steel into the v-con clamp it was a tight fit and i think it would have scraped off the paint, and then i had to use a hammer to force it left or right a little, which would further scratch off paint...

i think a machine coating like ger is recommending might be the best plan.

I wipe down my rails and racks with acetone then apply Super Lube 51004 Synthetic Oil with PTFE, High Viscosity, 4 oz Bottle: Fishing Equipment: Amazon.com: Industrial & Scientific (http://www.amazon.com/gp/product/B000UKUHXK) to the rails and Super Lube 54432 Synthetic Gear Oil ISO 460, 1 quart Bottle, Translucent: Amazon.com: Industrial & Scientific (http://www.amazon.com/gp/product/B007UU9V8A) to the racks and pinions. I have only done it twice since building my machine, and only plan on doing it twice a year on the extreme season changes. A little bit goes a long way, and the grease is very thick, almost like corn syrup.

I did paint the racks. Everything but the teeth.

I tried grease to start with, but it became a problem. I cut polycarbonate mostly on my machine. Those little bits stick everywhere there was grease. Now I am using a dry lube with graphite. It is measy too. I had been using another dry lube with PTFE and I will be reverting back to it.
I'll post the name when I can. It worked fine. I just wanted to try some other products that I had on hand.

Here is the dry lube I used on my old router and have started using it on my CRP router now.
