« Part 14: How do I get the best out of an OLD DELTA 40-650 Type I? Need experienced advice! Part 15 of Getting my tools ready series Part 16: Re-purposing a shop bench to a woodworkers bench »

This has been a learning experience in what not to do. LOL! Saw this scroll saw for 75 bucks on Craigslist. Drove to the house down dusty country roads and I blogged earlier about this saw requiring a couple hours of fixing the clamp to see it cut wood! Then I drove home in a snow storm.

The first picture is how the saw looked in January!

The second picture is how the rusted table looked. I got some suggestions from Blackie (Randy) regarding about using apple cider vinegar to remove rust. This large table top would have required a big bucket. I figured out how to soak the table with the vinegar using paper towels and a large heavy duty trash bag. After a couple days it took most of the rust away and then I hand rubbed with cider vinegar and paper towels. Then water rinse , dry and used polishing compound followed by paste wax. Looks pretty good!

The third and fourth pictures are of the over engineered clamping mechanism. I had put the saw back together after greasing the one major bearing. ( Different from later saws which have more bearings and a different style arm and better clamping systems.

When I put the saw back together and attempted to run it up to a non vibrating faster cutting speed the clamping mechanism and blade broke spraying the little parts of this pretty but over complicated clamping system. No spare springs! I ordered them from e replacement parts and got the parts 60 days later! I used the internet to find some pictures of how it is assembled because the shop manual was useless!


The next two pictures 5 &6
show the removal of the o ring holding the bearing in required the purchase of some ring pliers and I purchased some synthetic racing lubricant and needle valve, as it was recommended in a YouTube video in rehabbing a newer scroll saw with many bearings.

I also removed and replaced the bolt that ran all the way through and shared the lower clamp space. It requires tightening and loosening two locking mechanisms but frees up that space for the clamp alone.

Picture 7 is the completed scroll saw.

There is more that I did. I asked the scrollers on LJ’s for suggestions and advise. They haven’t been down this road but made suggestions, which I appreciate. I put wheels on with castors as my shop is getting smaller with new tools and requires set up now. Bought the wrong locking castors. Didn’t lock the pivot bearings. WOBBLE WOBBLE! More cost and time?

What is ironic is it still does not work as I expected. I purchased a Craftsman scroll saw 16 inch on sale with a cast iron table and simple lock mechanism that I saw reviewed on YouTube. ( This is what I might do today after this long detour from my purpose in buying a scroll saw to begin with!

I have no mentor so I am fumbling through. Even on a expensive Excaliber scroll saw there is a large amount of drift when cutting, similar to cutting with a band saw.

Found that out from watching scroll saw cutting basics on YouTube again.

It’s not easy to cut this stuff as it appears when the demonstrators are doing it. Then when the tensioning mechanism is poor it doesn’t help. Well it’s not a big door stop anymore.

Thanks for looking and comments welcome!

yhis looks to be like the one i have, it looks like yours has a light, i dont have that, besides that is looks very similar…if you weld a chain onto the motor area, it will work as a great anchor..so sorry you had so much trouble

Good job rejuvinating this saw, Tom. I believe it’s a very satisfying experience.

Now the big question: How much do you want to it now ? ;-)

Best,

Serge

Grizz,

Thanks for commenting. :<) Hope you are feeling better. The light is from my old office. Don’t have a welder. LOL! Or a boat.

It has been a learning experience about saws. I know you’ve commented on my journey. I appreciate your support.

Serge,

Thanks for checking in. I’m going to do some comparative cutting. Found some good instructions on YouTube. If I’d have spent all the time learning to cut I’d probably have my intarsa project done? LOL! Your support is appreciated.
