Picnic Table

Kansas City Art Institute | June 2013

[two_third]kansas-city-art-institute_picnic-table_blog-entry1[/two_third][one_third_last]1. I had a template cut out on the cnc router and went about cutting the thick gauge aluminum square tubing to fit the pattern.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry2[/two_third][one_third_last]2. Here is a good view of the heavy gauge steel bracing that slides in the aluminum structure prior to welding. The reason we did this was not because the aluminum tubing wasn’t strong enough rather it was because the welded aluminum joints once ground smooth would be susceptible to cracking. The steel takes the stress off of these welds.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry3[/two_third][one_third_last]3. You can see how the steel bracing slides in the tubing. A really snug fit but not to snug was critical here. [/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry4[/two_third][one_third_last]4. Here is a close up of a typical joint.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry5[/two_third][one_third_last]5. Viola, here is a complete assembly ready for welding. [/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry6[/two_third][one_third_last]6. Once I had one of these assemblies welded together I used it as a template to align the remaining two.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry7[/two_third][one_third_last]7. A close up of a typical aluminum TIG weld.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry8[/two_third][one_third_last]8. The holes in the top of all of the exposed tubes had to be welded shut to prevent water from entering the assembly. This was a pain.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry9[/two_third][one_third_last]9. A complete assembly after welding, grinding and sanding. Pretty![/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry10[/two_third][one_third_last]10. Ok flash forward. Essentially the rest of this piece is comprised of six frames, two of which you can see in this pic bolted to the three leg assemblies. [/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry11[/two_third][one_third_last]11. Here is a shot of that bolted connection. Notice the tabs that are for mounting the stone top.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry12[/two_third][one_third_last]12. Now we have added the additional four frames where the seat platforms will rest. This assembly design makes this table a snap to take apart.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry13[/two_third][one_third_last]13. You can see in this pic where we use dots to denote that these parts assemble in this configuration.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry14[/two_third][one_third_last]14. The seat pans have been installed.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry15[/two_third][one_third_last]15. There were quite a few of these flush machine screws to countersink and thread.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry16[/two_third][one_third_last]16. Ship it out to paint! Notice how compact it is when broken down.[/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry17[/two_third][one_third_last]17. Here are all of the parts except for the seat pans sitting on the dock at the painter. [/one_third_last]

[two_third]kansas-city-art-institute_picnic-table_blog-entry18[/two_third][one_third_last]18. Black beauty. Here is the table at Carthage marble for the installation of the top.[/one_third_last]
