The picture below,  illustrates where the magnet is located.</B></div> <bR> <div> <B><IMG SRC="5c8cc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>Next, let us see a missing snap on a brake toggle:</B></div> <bR> <div> <B><IMG SRC="5c9cc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>We will notice that there is a back round plate in between the two toggle webbings that needs to be removed if still in place.</B></div> <bR> <div> <B><IMG SRC="5cacc140.jpg" border=0 width="460" height="276" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>Reusing this back plate is not a good option since in order to hold the brake well, the snap needs to have a bigger mass.</B></div> <div> <B>Therefore, I replaced this plate with a washer.</B></div> <div> <B>The parts we need are:</B></div> <div> <B> a washer and a flat head bolt as seen below.</B></div> <bR> <div> <B><IMG SRC="5cbcc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>The replacement washer needs to have holes drilled in it so it can be sewn on the webbing. After drilling the holes, I recessed them so the stitches will not be above the washer:</B></div> <bR> <div> <B><IMG SRC="5cccc950.jpg" border=0 width="460" height="405" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <div> <B> </B></div> <div> <B>The next operation is to solder the flat head bolt on the washer.</B></div> <bR> <div> <B>  <IMG SRC="5cdcc360.jpg" border=0 width="460" height="310" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>After cleaning,  we will have to trim the bolt in order to fit it on the magnet while the washer is flat against the magnet.</B></div> <bR> <bR> <div> <B> <IMG SRC="5cecc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B> Once more, we should remember that before sewing the snap on the toggle, we need to check if it fits perfectly on the magnet. Once this is done, we can sew it on the toggle.</B></div> <div> <B>If the snap does not touch the magnet's rim or the blot is too long, the brake toggle will not be fastened sufficiently and may fall off. If the bolt is trimmed correctly, it will hold the toggle just as the original one.</B></div> <bR> <div> <B><IMG SRC="5cfcc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B><IMG SRC="5d0cc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>Next, we  will see the difference between the original snap and the one we just made:</B></div> <bR> <bR> <div> <B><IMG SRC="5d1cc590.jpg" border=0 width="460" height="345" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></B></div> <bR> <div> <B>The new snap is not identical but it will work very well.</B></div> <div> <B>Of course, if one has the possibility to replace the broken snap, it is better. However, this repair allowed me to get up safely in the air, the very next day after losing the snap.</B></div> <div> <B>   </B></div> <div> <B>   </B><FONT SIZE="3" COLOR="#FFFFFF" FACE="Lucida Handwriting" ><B>Alex Varv</B></FONT></div> <bR> <bR> <bR> <div> <B>          </B><A HREF="index.html" TARGET="_top" TITLE=" "><U><B>Back to Inventions</B></U></A></div> <bR> <bR> <bR> </td> </tr></table></body>
