Refurbing a Scroll Saw

[JPG]

I acquired a ss mount Scroll Saw last week and have decided to take Y'all on the journey to restoring it. It is not in bad condition, but is in need of 'cleaning' up and some TLC and a few parts replaced. The PO had a sick spell and he had not used it recently. He was acquiring :eek:Stand alone:eek: replacements. Real nice Guy!!! Never met him b4.

I will attempt to create an index here as I proceed.

This is an older gray model that I believe is late 80's genre.

After evaporust wire brushing and JPW(original)

The evaporust removed the black oxide as well as the 'red'. I will retain the 'natural' finish and hope the wax does its thing.

Not sure it is significant, but the rear trunion pin was loose. I do not know if the PO loosened it to make tilting easier. I doubt it and think it just came loose on its own.

I have started with the most accessible stuff and the table is next!

Wow what a difference! That evaporust really works nice! Great job.

They come out of the evaporust with a thin grey colored finish. Light wire brushing brings out the 'shine'!. The screws were plated to start with so they are merely cleaned up.

Take one of those 20 percent off coupons with you to Harbor Freight and save $4.00 on a gallon of Evaporust.

I have an older grey scroll saw which needs some work, so I am looking forward to following along on your refurb of your saw! Thanks for posting.

I decided to change the gray color to the Goldie combination. I discovered the original gray paint is impervious to Citrusstrip AND Lacquer thinner. Therefore the original gray is now a primer! The outer edge of the table and the trunions are painted Rustoleum Hammered Coppertone.

Table after

Not as evenly colored as I would have liked. Discoloration removed by light wire brushing. The original finish is quite rough so polishing is out of the question.

The casting of the slotted holes was quite rough and you can see where flash has rubbed(interfered) the mounting screw.

Rear Trunion Mounting Hole After

The slots have been filed to remove the interfering flash.

Front Trunion After
[ATTACH]13040[/ATTACH]
The upper arc(lower in the upside down pix) was masked off. The degree scale was painted over, then after the paint set slightly, masking tape was pressed onto the areas where I wanted the paint removed. Once the paint was nearly dry, light rubbing with a cloth and citrustrip removed the remaining undesired paint between the lettering.

As I mentioned earlier, the pin was loose on the rear trunion. The reason it was 'loose' is that the trunion bracket does not provide adequate clearance for the segment to rotate in the bracket.

Rear Trunion Pin shimmed
[ATTACH]13041[/ATTACH] EDIT I have since 'discovered' this was intentional so it could act as a clamp. 5-21-2011

The pin needs to be shimmed about .060". The washer is about .050 and the paper under the washer is about .010. I will fabricate something close to .060 thick prior to reassembly.

Today I scavenged a piece of steel about .060" thick, and made a shim for the rear trunion pin.

The material was originally a cheap stamped faucet wrench in a box of garage sale junk.
