Worth working with or send to the dump???

[gpd132]

A coworker gave me his Mark V a couple days ago. He was going to take it to the dump. He told me it had not run in 10 years but I told him I would take it. I had no idea he stored it outside. It does not run and many parts are rusty. It came with 2 tables, lathe attachments, scroll saw and band saw. I am currently trying electrolysis to clean up some of the parts. I don't know if I should part it out, junk it, or buy a used headstock and use it. I guess it depends on how successful I am with the rust removal. I attached a few pics. My 2nd biggest issue is trying to remove the way tubes from the mount (pic also included). It is frozen in place. I've tried PB Blaster and Kroil and it won't budge.

Any tips or ideas/suggestions are appreciated. Thanks.

I wont say about the motor, but the rest is salvageable, the motor maybe good with just some surface corrosion, try and fire it up, and others here with more X then me will chime in.

Judging from the headstock, that machine is relatively new. Can you show us some pics of the tables and fence? If it is a 520 model, it's worth some extra effort.

Just how much effort is a personal decision. But it can certainly be restored. If you want inspiration, spend some time perusing this thread. Or better yet, go straight to the results page.

It looks like a challenge but if you are up to it the end result will be worth all of the blood, sweat, and tears. Like the rest, I look forward to seeing the restoration progress.

You can get a good working 1980's+ headstock on eBay for $200 + shipping if you bide your time or make some offers on ones that allow it. If you find the headstock portion too much of a job but want to keep the rest. Just food for thought.

Ok, it will sound a bit odd but here goes;

On the way tubes, cut two 2" PVC Pipe sections a few inches longer than the rusted sections and place them over the rusted tubes.

Take some silicone sealant, and place a bead around the outside of the PVC pipes to seal it in place allowing Evaporust to go down the outside of the tubes through the base etc. to free it up.

Stand it up in a oil pain, pail etc, and keep it upright.

Fill the PVC pipe to an inch or more above the rust line with Evaporust.

Put it in an area that is 70 degrees or so, and wait about 10 hours, checking it throughout the day and topping it off.

Capture any of the Evaporust liquid that flows through in the pan. You can reuse it several times after you filter it through something like a coffee filter etc.

If it is coming apart, that is the ticket to get you there.

If it just pours through, you may have to silicone seal the tubes at the base.

You can peel off the silicone when you're done.

You may have to do it twice. I did one that stayed submerged in hurricane Katrina surge waters for two weeks, then sat in a warehouse for a year, by ripping pvc pipe down the middle and silicone sealing the ends at the tubes and the seams of the pipe back together. Drilled a hole to fill them and duck taped them in place preventing it from rolling the fill hole over.

Don't give up. It's doable. Darn I wish I had taken pictures, but it was a buddy's machine he salvaged for nothing. He wound up buying absolutely no parts when it was finished, other than paint.

Good luck on your Lazarus project! Please take pictures along the way. It is an amazing opportunity, and a good find.

Use Marvel Mystery Oil on a rag and rub the aluminum parts down to get rid of the crud and the oxides.

If the motor is dry, and free from contaminants, and rotates freely, you could try to power it, but I would tear it down and clean everything first.

Search the first two posts in Maintenance threads at the top and you should have a roadmap to do what needs being done.

There are folks advertising on eBay who will rebuild your motor for you reasonably priced. They would need a photo to show them the condition and could get you a starting price if you want to go that route.

They are set up for that sort of work and have all the tools and processes down.

Just an idea you might kick around if you aren't comfortable inside the motor or are concerned you might damage it beyond repair tearing it down.

What everett said about the pvc tubes and evaporust, works like nothing else.

The tubes don't even look that bad. I just did one that had heavy rust the entire length of the tube. The came out great and with some polish are shiny again.

As already stated, that unit is definitely recoverable. It will be a bit of hard work but it can be done. If any part of it is DOA it will be the motor. You'll have to open the motor to determine that.

If you decide that you do not want to take on this task, PM me. We might be able to work a deal on the headstock.
