Refurbing a Scroll Saw

Continue by attaching spring to lower arm, shimming upper arm cover and positioning spring washers.

Place shaft in lower arm bushing, place into right side bore, and secure with flat washer, lock washer and screw. Attach free end of spring to lower arm.

Not clear from this pix, but the rocker assembly is secured to the upper arm by a screw.

[ATTACH]13295[/ATTACH]

A spring washer is placed over the upper and lower arm shafts. The upper one is raised so better 'see' it. They are positioned so the shafts are centered in them.

Position the left side onto the three shafts then, shims are inserted between the left side and the upper arm cover and secured with the screw, flat washer and lock washer. The ss parts diagram shows one shim. but there were two when I disassembled it.

Finally secure the left side with three screws/flat washers/lock washers.

Almost done!!!!

Air tube is attached to the air pump outlet and slipped under a tab on 'counterbalance cover'.

As promised, here is the 'tool' holder mounted using the po original power cord strain relief hole.

Left to right blade alignment(table tilt). No zero stop, so accuracy requires setting properly when using.

Front to rear blade alignment. This is adjusted by moving the rear trunion arc up/down. Although the 'shimmed' rear trunion is a bit 'sloppy/loose' I am keeping it as is. IMHO it is does not move enough to affect cutting accuracy, and eliminates the need to loosen it when adjusting table tilt.

She's done!

This has been a bit of a journey.

I did not pay much for her and did not expect her to be perfect. I did not expect to have replace all the bearings etc. Fortunately it was possible to do so(not always the easiest thing[arm bushings], but still achievable). Parts acquisition (bearings, bushings, broken/bent parts, lost(by me) parts and altered(by me) parts more than doubled the 'cost'. Still a bargain!!!

And she is now part of a 'matched set'(goldie) which will soon expand to include more 'matching' gizmos.

The 'new' tensioning rod will work if I decide to upgrade to the new blade mounting scheme. In the mean time, I will try 'the old way'!

Oh! BTW Here she be!:D

She has to be an improvement over the jig saw.

I have the 'stickers' to cover the center shaft screws etc. but am delaying attaching them until after a shake down 'cruise'.

You did a beautiful job JPG. It looks better than new. It was great taking the ride with you.

This is certainly an inspirational achievement and one that anyone would be proud to display and use. In fact it's too nice to use. This is the kind of quality postings we all love to see.

IMHO there is NO SUCH THING as a tool that is "Too nice" to use. Tools are built to be used and are happiest when being used.

I've never seen a well used tool that was overly rusted. It's the derelicts laying around not being used that break down because they just aren't happy.

JPG, Great job on the restoration and I wish you many hours of happy use!

Right on! Form vs. function......I go with function. Great job JPG. Did you fix the bottom of the arm castings? I could not tell from the pics.

No 'need' to. Function not damaged, only Form.

I neither purchased the saw to place in a museum nor 'function' as a dust collector.

It shall be used as originally intended(and probably a few not envisioned by the designers(ADHD symptom -too much imagination!:D)).

I suspected as much and would have taken the same route for personal use. Of course, there could have been a new thread "How to repair an aluminum casting".........]
