Oh... its SO good to hear that no MDF or chipboard will be used... it just doesnt hold up over time.... good move by Jack to use quality ply instead
What are the pins made of we have now that are 20 to 30 years old and you say "they don't hold up" ???? I reckon they have done ok sited in all sort of locations in all sort of weather conditions.
