Graphika strap repair

End of strap folded over the hook and tapped flat
A hole punched through both layers with an awl into hard-ish wood so as not to deform the metal strap too much. The metal is easy to trim with tin snips or possibly even scissors. I used tin snips. A short length of solder.
I punched a hole into a piece of wood for the solder to fall into when melted through the hole in the strap. Sort of a well to make a rivet-type head.
Top of the solder. Not enough hands to actually show the soldering process but if you have a soldering iron, you'll know how it works.
Bottom of the solder. Makeshift rivet head flattened (carefully) with a hammer.

Graphika journey



Upside down carriage
Note the three register slots. Two on the left, one on the right.
The alternate spacing lever (on left) has to be removed before the cover. Bike spoke indicates its screw hole.
Fire basket meets word processor
'Spare parts' from the bottom of the box. L-R: strap hook, broken piece of strap, random spring
Pretty obvious where the random spring had to go
Don't say "pistachio", say "mushy peas"

Next time... how to fix broken steel carriage strap/drawband...
