The September Equinox and Look at what I just found!

Sine and Cosine waveforms.

Today is an equinox, a day of the year when the length of of time between sunrise to sunset is equal to the time between sunset to sunrise and the sun is directly overhead of the equator. Here in the northern hemisphere it is the autumn equinox and nights will

Stiffening up the Homemade Box and Pan Brake

The brace to stiffen the box and pan brake.

After doing a lot of work in previous tests I determined the brake could get the job done on small pieces of metal but just could not get it done on longer pieces because the hinged board was bowing when I applied the force necessary

Gap between the hinged board at 90 degrees and the base board with no metal.

Another step forward with the brake project. I cannot say the light at the end of the tunnel is very bright yet, but I am pretty sure it is not a train. I am a whole lot more hopeful

Putting the Head on the Crane Boom.

The Crane Boom is almost complete.

The crane boom is almost complete! I put off doing the most difficult part, the head or nose of it until last. The reason this part is the most difficult is it narrows in both directions. The base or butt assembly did not get any narrower across the

Why I built the Crane Boom Hinge the way I did.

The Plan for the Crane Butt.

Last night’s post, Popsicle Crane Update 3 was almost completely about construction of the crane boom hinge end (the “butt” end – a real term used by the crane industry.) I realized on the way to work today I did not talk about why I did what I

The Plan for the Butt of the Crane Boom

Much progress has been made on the construction of the popsicle stick crane. At the last crane update I had built built the major part of the boom and some pulleys. Since that time I have figured out how to make the pulleys spin fairly

Popsicle Crane Update no 2

A side view of the boom.

It has been a little bit since I have talked about the popsicle stick crane. Work is still proceeding but there is not a lot to show yet other than a few work in progress pictures.

I have built the main part of the boom and this time

Buckling of the Popsicle Crane Boom

A beam buckling

We have put quite a bit of effort in understanding the forces on the crane boom. Now we need to start figuring out what we are going to do about them. (Refer to the post crane-boom-analysis-part-2) The fact that the whole boom is under compression loading explains a lot to me

A problem with scaling, and the popsicle stick project

Picture 1: Getting a feel for the strength of glued popsicle sticks

The whole idea of working with popsicle sticks was that they are relatively inexpensive and require little work space. I thought that it may be helpful to people little money and space to work with something to get some experience designing and

A good book and a good website.

I decided when I built this site that if there was better information somewhere else I would point toward it. That is what this post is about. I am going to recommend a book about using a router and also a very good website about popsicle stick bridge design.

The New Router Handbook

A router
