I copied these instructions for disassembling a grafmatic off a website years ago. I've never tried it. Hope it helps somebody sometime.

To remove the index wheel proceed as follows: READ ALL STEPS FIRST! <BR>

1). Remove spectrums <BR>

2). Place dark slide handle facing you with dark slide up. <BR>

3). Locate and remove screws on the sides of the frame closest to you. <BR>

4). Slide inner housing from outer housing. NUT PLATES THAT SCREWS ATTACHED TO WILL COME OUT! Pay attention to their position for reinstallation. <BR>

5). Hold dark slide lock wheel and remove its screw. SPRING AND SMALL BALL ARE UNDERNEATH! Also there is a brass washer. <BR>

6). Carefully lift lock wheel off and remove ball and spring. <BR>

7). Remove screw from other end of the same plate. <BR>

8). Remove dark slide end plate; lock lever and dark slide may have to be manipulated. <BR>

9). Position as in step 2 and pull dark slide out as far as it will go. Push in slightly and feel (find) catch lip on right far edge bottom of dark slide. A 5/16 square block on a spring engages the dark slide lip to prevent it from coming out. <BR>

10). Insert a .020 to .025 feeler gage (or something similar) between the dark slide and the spring loaded retainer block, and remove the dark slide. <BR>

11). Lift index wheel off its spindle. <BR>

12). Hold down dark slide retainer block and reinstall dark slide in its slots and push past retainer. <BR>

13). Continue to reassemble in reverse order. A small dab of Lubriplate or white lithium grease applied to the bottom of the dark slide lock wheel will aid in holding steel ball in place. Screw has a sholder that wheel must set on to function properly.<BR>

<p>Hi !<br>

The springs you are reffering to are simple flat springs. The major problem is that they're rivetted into the Grafmatic.<br>

You may go to a place doing mechanical job and ask they to cut spare spring in spring steel sheet. If they can't do the job they may know someone near you able to do it.<br>

Then you'd left with the rivetting problem I suggest you spoke about to them ....<br>

I've made replacement springs (but not for Grafmatics) on the ribbon steel one used to circle crate for shipping. excellent steel but cutting like a razor blade so be VERY careful !</p>
