So with the skeleton/frame complete I figure out the cuts for the strakes in AutoCAD. Strakes are the panels or planks that make up the skin of a canoe or water craft.
I then print out the design on A3 sheets and tape it to the 4mm marine ply which I’m using for the cladding.
The strakes were then cut out.
Then attached to the skeleton.
I moved outside and started stitching the remaining strakes together.
At this point I had loosely stitched up the majority of the canoe, except for the ends.
I wasn’t confident enough with what I came up with in CAD so I had not cut the ends of the strakes to ensure I could get the curve I wanted. So I had to clamp the ends tight and stitch up my freehand curve inside of the cut that was going to be made. I then freehanded a jigsaw away from the line for later filing and sanding back.
I then put a couple of temporary gunwals and spreader on so I could carry the shell without it collapsing.
So the templates for the skeleton have been cut out and its time to form the strongback to hold them. I had some kitchen laminate board lying around so I decided to box it up and attached the skeleton with droppers down to the strongback. The strongback is there as something to fix to, keep everything straight and be able to do measurements from. How I did it was fairly dodgy as it had about a 10mm bow in it if supported in the center only, but with taking this into account it worked. There are way better examples of how you should do it on the internet, most involve having the strongback inside the frame pieces. You would cutout holes in each piece and slide them over the strongback. Anyway, heres some pictures…
Picking up where I left off, we were transfering the design to the ply.
Great helper transfering the plans to the marine ply
Now I needed to predrill a hole on each junction point so the jigsaw could be turned. I offset my holes outside of the frame pieces, but it probably would have been easier to do it exactly on the points. The small amount of the hole that would have been left in the two bulkhead pieces later would have been covered by an epoxy fillet. Because I didn’t think of that at the time, when I began cutting I had to cut small triangles out at each corner to rotate the jigsaw correctly.

THE FIRST CUT!!

After a short celebration (VB), I ripped through the rest of the sheet.
Cutting the rest of the frames out.
Frames all cut out.
It was starting to look like some progress was being made at this point and I was excited, I recall saying to someone that it would only be a couple more weekends until it was completed. HAHAHA im such a kidder..
When working on http://www.dssa.com.au!LINK BROKEN! I had to figure out how to find the nearest driving schools to the users location. To do this I needed to geocode their address (convert their address to Latitude and Longitude) and check it against my database of driving schools. My database contained the driving schools addresses already geocoded so it was then just a matter of comparing the two. I created a Geocodetestsuite that compares the performance of various ways I have used to calculate the distance.
NOTE 4.11.2016: previously the performance of option 3 took the longest however with the resurrection of my blog I see that the microtime for it is not comparable with option 1. I have not had the opportunity to review why this is.
A Driving Schools management system I made, notice the plural. Australia wide search with maps. Integrated online Freecall systems. Lesson Booking System. Mobile Booking Systems. The site is http://www.dssa.com.au/.
A long, time ago I put together a Single Driving School management system with PHP and MySQL. It included a Lesson Booking System. Mobile Booking Systems for use with PDA’s or Mobile Phones and it also had SMS Alerts. The site is still going and you can check it out at www.drivewelldrivingschool.com.au!No longer my work!.
It was a long time ago and I had an interest in 3D design at the time, note all the images and video I made using Blender, they took a while and were fun to do. I thought they were AWSOME, however my opinion has changed with time, watching the video I made with blender and windows movie maker now is so painfull (check it out – Drivewell Booking System Video).!No longer available! I even started making a 3D game for the site. But as the plugin used for it has long been abandoned it doesn’t work so well on newer systems(if at all now).
Orders can be placed any time of year and repayments deducted automaticaly from clients accounts throughout the year until christmas day when they receive the goods. Repayments can be made weekly, fortnightly, monthly or a once off outright payment. The system divides the total value of the purchase by the amount of repayment periods that are left in the year and deducts the correct amounts from the clients accounts on those days. If a payment is not able to be made due to insufficient funds it is automaticaly retried each day until it succeeds or is manually processed.
The client online purchasing was a streamlined one way process to suit the business process that was outlined for the original project and manual ordering and modifications can be done by staff in the administration section.
What I found was the way you program for Joomla! is well structured, I liked how it was setup to create an installer for the system and how easy it is to apply my custom component to a clients existing installation. If you follow the design pattern they have setout and don’t try to hack in some existing piece of software but rather create something for Joomla! that does what you need, the result is good.
It was a project I really enjoyed and a great way to learn about Joomla!.
I purchased some British Standards marine ply for the canoe. 4mm for the sides and 9mm for the frame. It was my first investment other then time. The delivery was quick and not to expensive and it was great to see it when I got home from work stacked nicely in the garage. It took a while for me to realise that they must have just thought “Oh, nobodys home! Lets just open up their garage door anyhow and put it inside for safe keeping..”. Not to worry I guess, as nothing was missing.

Opening up AutoCad to checkout the plans one last time. You can see how I drew the ply sheet and overlayed the sections on it. I then overlayed an A3 sized rectangle onto of them both. I used it to select my exact print areas. Also note I checked out the legal issues with carrying it ontop of my car, it’s legal but I’m still not sure if I will.
After a final check I began printing out my plans for the molds in 1:1 scale, I taped them onto the thicker sheet of ply.

Plans for the molds taped down ready for cutting.
The sheets all line up perfectly when joined exactly edge to edge. Some points are just outside the printable area on the sheets, but by extending the lines im able to form the points correctly.
