Tricycle construction notes and resources
This isn't a normal blog post. Normal blog posts are typically rarely updated. I intend to update this fairly regularly as ideas occur to me.

Was Charlie Kirk a Christian?
A person by the name of Charlie Kirk was shot dead on a university campus in Utah, USA, this month. This piece is not a defence of his assassin. No one should be killed for their political opinions. However, the claim has been made — not least by Kirk himself — that Kirk was a Christian. As an ex-Christian, and as someone concerned with both theology and ethics, I want to examine that claim.
What are my qualifications for deciding who is and is not Christian?
I have none, and do not decide. I am agnostic precisely because I believe that it is blasphemous to make any strong claim about the numinous. I shall set forth the evidence, and leave the decision for you.

Learning from CAD
As I reported in my last essay on the tricycle project, I now have a CAD tool which I'm learning to use. So, learning to use it, I'm beginning to be able to visualise the tricycle, if not yet concretely, at least as an assembly I can look at and study. And doing that brings up several things.

Details, details
Details, details
Thinking about how the tricycle will go together means thinking about a lot of details. One of the first thing that needs thinking about in detail is the four-bar linkage, since if that does not work the whole idea does not work and there's no point in investing quite a lot of money in laying up the hull.

I have, as I wrote in my last post, real difficulty with learning 3d modelling software. Every system I've tried has a really steep learning curve, the commercial systems are extremely expensive making them very hard for me to evaluate, and some of my cognitive quirks just get triggered when trying to use them.
