Hi all. Please delete this if this has already been done. But i wanted to share my fix for the lower tape draw lock pin.
Like most, the plastic locking pin was broken and missing on my tray.
I started by drilling a 2mm hole where the pin was located.
I then i chose to use a central locking rod as the missing pin as it fits perfectly in the locking guide mechanism
I then, using a power file (or a bench grinder) tapered the rod down to 2mm so that it would fit into the drilled hole.
I cut it to about 21mm long and filed the head smooth so that it wouldnt cut into the plastic guide as it moved around.
Inserted and lubricated the guide with some silicon lubricant.
I didn't glue or set the pin into the tray. The guide channel holds it perfectly in place
And heres a video of it in action.
