+## Table design 
 
-## Code Example
+I used the following picture as a basic inspiration for my table 
 
-Use the three backticks to separate code.
+![Inspiration](../images/imagW7/0Table.jpg)
 
-```
-// the setup function runs once when you press reset or power the board
-void setup() {
-  // initialize digital pin LED_BUILTIN as an output.
-  pinMode(LED_BUILTIN, OUTPUT);
-}
+Hight:  I started by looking up hight for table and is seems that card and dinning tables are typically 28-32 inches high. Work 
+ table are 28-30 inches and so I decided to go with 30 inches 
 
-// the loop function runs over and over again forever
-void loop() {
-  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
-  delay(1000);                       // wait for a second
-  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
-  delay(1000);                       // wait for a second
-}
-```
+able top size: I decided to go with the biggest I can make which is going to be 48 inches 
 
-## Gallery
+Floor base: I found on line that the “golden rule” is to have the width of the base at the floor be at least 0.6x the overall 
+height of the table. As this is the minimum I wanted to have a very stable table and decided to use 0.75 as the ratio.

+Table leg width: I will use 6 inches
 
-## Video
+I plan to make this with a glue up of 3/4 inch hardwood planks (see next section)

+First up a set up a few parameters I plan to use based on the design approach I listed above

+Next I started with the table top and slots

+Circular patter repeat make this a quick one 
+
+![Design](../images/imagW7/3Top.jpg)
+
+Next I started on the legs and was wanted to ensure the end of the leg  can slide into the the 
+slot in the table top
+
+![Design](../images/imagW7/4leg.jpg)
+
+I set up the basic shape and mirrored in the sketch to ensure the legs were symmetrical - this was my 
+first mistake as a later found out that mirroring in the sketch does not work as well a mirroring 
+the extruded part when changing the user defined parameters 
+
+![Design](../images/imagW7/4leg2.jpg)
+
+I got the legs ready with the cross fit joint 
+
+![Design](../images/imagW7/5Legsandtop.jpg)
+
+Next I decided to check fit in fusion and good thing I did as I has the slots misaligned 
+
+![Design](../images/imagW7/6miss.jpg)
+
+This called for a new parameter and I used sketch dimensions  restriction to ensure they will line up
+
+![Design](../images/imagW7/7legredo.jpg)
+
+I used the same parameter in the top and leg to ensure alignment 
+
+![Design](../images/imagW7/8aligned.jpg)
+
+and another check - we are good to go 
+
+![Design](../images/imagW7/8alignedslots.jpg)
+
+
+Now that we get that working I decided I really did not like the look of the legs and so it was time for 
+design #2
+
+![Design](../images/imagW7/newleg1.jpg)
+
+I repeated the steps above and had the next set of legs ready 
+
+![Design](../images/imagW7/Z2legswithjoint.jpg)
+
+When I wanted to resize the legs the sketch profile kept coming apart and so after some research I decided to
+redo this once again the this time to use the 3d mirroring instead of the sketch.
+
+So here we go again
+
+![Design](../images/imagW7/Z3newsketch.jpg)
+
+
+I extruded on this part 
+
+![Design](../images/imagW7/Z4newleg.jpg)
+
+then mirrored it in 3D
+
+![Design](../images/imagW7/Z5newlegmirror.jpg)
+
+duplicated and added joint 
+
+![Design](../images/imagW7/Z6newlegs.jpg)
+
+
+I downloaded a [Dogbone add-in](https://apps.autodesk.com/FUSION/en/Detail/Index?id=3534533763590670806&appLang=en&os=Win64) for Fusion and got the design ready to cut  
+
+![Design](../images/imagW7/newleg2dogbone.jpg)
+
+and now we are ready to mock up in the laser cutter 
+
+![Design](../images/imagW7/newleg3final.jpg)
+
+
+
+
+## Laser cut mock up 
+
+Next I took the basic table design and laser cut a small version to get a feel for fit and look 
+
+![Mock up](../images/imagW7/C1cut.jpg)
+
+
+![Mock up](../images/imagW7/C1cut2.jpg)
+
+
+The table looked nice and legs seem to align well to the table top slots 
+
+![Mock up](../images/imagW7/C2Table.jpg)
+
+When I showed it to my kids they started playing with it and turn the legs upside down. This looked much 
+better!!! 
+
+![Mock up](../images/imagW7/C3.jpg)
+
+Now I needed to get back to fusion and redesign the legs. 
+
+
+
+## Leg design #2
+
+To ensure i keep the slot in place I created a plan on the bottom and projected the 
+slot on it
+![Design](../images/imagW7/Z8flipingslot.jpg)
+
+Then I saw that the leg was too narrow in that part
+
+![Design](../images/imagW7/Z9Project.jpg)
+
+I extruded it but need to get the base back in line 
+
+![Design](../images/imagW7/z9project2.jpg)
+
+So a went back to the sketch and adjusted it 
+
+![Design](../images/imagW7/ZProject3.jpg)
+
+That looked good 
+
+![Design](../images/imagW7/ZProject4.jpg)
+
+Now I needed to erase the old slot 
+
+![Design](../images/imagW7/ZProject5.jpg)
+
+and this looks 
+
+![Design](../images/imagW7/ZProject6.jpg)
+
+And we are good to go
+
+![Design](../images/imagW7/ZProject7.jpg)
+
+## Cardboard test #2

+
+## Wood glue up
+
+Chatting with Dr. Taylor about the table he had a great suggestion of using a glue up of hardwood to take the 
+table to the next level. This was a great opportunity to learn 2 new things:
+
+1. How to glue up hardwood panels 
+
+2. How to use the [Festool DOMINO Joiner](https://www.festoolusa.com/products/domino-joining-system/domino-joining-machines/576423---df-500-q-set-us) our lab has. 
+
+![](../images/imagW7/W1tool.jpg){: style="height:300px;width:300px"}
+
+
+I headed out and got some nice wood planks
+
+
+![Wood](../images/imagW7/W1wood.jpg)
+
+
+Next was the joiner to make sure the side were nice and flat 
+
+![Wood](../images/imagW7/W2planer.jpg)
+
+Next OI lined up all the planked to get the patters 
+
+![Wood](../images/imagW7/W3setup.jpg)
+
+I marked the planked every 8 inches for each place I will put a domino/dowel 
+
+![Wood](../images/imagW7/W4marking.jpg)
+
+Next step was the drill holes at every marking for the dominos/dowels
+
+![Wood](../images/imagW7/W4waferdrill.jpg)
+
+Here you can see the holes
+
+![Wood](../images/imagW7/W5holes.jpg)
+
+Now I set up each plank put glue and inserted dominos/dowels 
+
+![Wood](../images/imagW7/W5holes2.jpg)
+
+You can see how the line up
+
+![Wood](../images/imagW7/W6Wafer1.jpg)
+
+Now started to run through putting in wafter and then inserting next plank and stacking them together. 
+
+I found out that it is very important to have the dowels all the way in to ensure a smooth stacking and 
+so you can see I use a maleate to ensure all the dowel are in and then again to put in the next plank 
+
+![Wood](../images/imagW7/W6wafer2.jpg)
+
+My dad who is 86 was visiting and come into the shop to supervise as I was working. He introduced me to 
+woodworking when I was a childe and while his arthritis does not allow him to do any woodworking we had
+a good time working together. 
+
+![Wood](../images/imagW7/W7stacked.jpg)
+
+Next I moved to the glues panel to a flat surface and I use 4 long clamps to hold the planks together 
+in addition I use 2 metal bars and smaller clamps on each edge to keep the panel from bowing as much 
+as possible. 
+
+![Wood](../images/imagW7/W8clamped.jpg)
+
+Another inspection approved
+
+![Wood](../images/imagW7/W8clamped2.jpg)
+
+24 hours later the board was dry enough and loaded into my truck to free up the space to work on the next 
+panel for the legs
+
+![Wood](../images/imagW7/W9loaded.jpg)
+
+I repeated all the steps above and now panel #2 is drying 
+
