Webster Flywheel – part 1

Posted by: Raynerd In: Webster Engine

I thought I`d give the flywheel a go this weekend. To be honest, I`ve had several hours on it but I`m a bit off completion yet although hope to get it finished over the next few days. I really really liked how this turned out considering it is made from a dumbell 2kg weight as suggested in the plans. I was warned that the casting could be very bad but it was perfect, not a single flaw!

Here is the weight on a stub I made. I was turning it very very slowly. This was to simply turn the edge so that I could grip it in the outside jaws.

Once gripped securely in the outside jaws, I faced one side. I then flipped it around so it sat flush on the back of the chuck and faced the other side until I had a nice slab. This required removing a lot of metal at slow speed so there was a good few hours of work just in this.

I removed it out of the chuck but marked its position so it could be returned. I then turned up a kernal for the centre out of brass and drilled and tapped the big end so that a grub screw can be used to tighten it onto the crank shaft.

I then silver soldered the kernal to the cast blank, cleaned it up and put it back in the jaws at the marked position. I then centre drilled and this will now go on an arbour throught the centre bore to clean up and finish to size so that everything is concentric.

Hopefully I`ll get it done in the next few days. I was just more impressed that these lovely disks of cast iron are available without a lot of looking!

Yes, and they cut really well. The set I had had no holes in them and I picked them up on the market for a few quid!

Welcome to Raynerd.co.uk

I`ve always wanted to learn more about engineering and electronics and my list of projects both complete and ongoing has been growing over the past few years. I like to document my progress more for my own understanding as much as anything, it helps keep me on track. I hope you can find something of interest to you, my clock building project is my priority but as you can see, I have many other builds I`m working on. Please leave a comment, it is nice to see people are reading!
