In this episode we sort out a few issues on the rear axle . . . .!

Enjoyed watching this, it took me back to when I had to make a pulley I first made them on the router in mdf to make sure the pitch was correct.

A few picks here including the cock up :- https://photos.app.goo.gl/t5dJpvh7dBWzp9TFA

Thanks a lot for sharing these videos, routercnc. I really enjoy watching them. I'm also working on a CNC machine and now and, thanks to you, I'm also thinking about doing something like this after finishing it. I will try to finish it by next summer because we will buy apartment in Portugal with a garden soon and I want my son to have fun outside.

Hi Clive
Yes, one wrong number in the calculations and the pitch spacing was wrong. An MDF prototype would have been a good idea. By the way I can’t open the pictures on my phone as it needs an app or something.
I ‘invested’ time writing a spreadsheet that works out the key geometry for any HTD 5 gear size you want. Watch me never need it again !

Hi pratt77
Thanks. Sounds interesting. Remember you don’t need anything as ambitious as my machine to make small parts. Whatever you build just leave yourself plenty of time as these projects eat up the months !

Finally got some motion on the rear axle . . .

As always, superb work, but you have an awful lot more patience (or engineering pleasure) than myself. Not tempted with shake proof washers on the bolts for the cover?

[routercnc]

Thank you. Yes, I think it needs something but clearance is a bit tight to the main plate. I'll see what might fit in there, or probably just loctite it after the first proper run.

The rather splendid 'Gearotic' software from Art Fennerty will design many common styles of timing pulley for you, along with gears, gear trains, sprockets, ratchets, clock escapements and more wonders than you could ever imagine. All for one modest updates-for-life payment.

Thanks Kit. Looks very interesting and comprehensive and as it is written or co-written by Art Fennerty (of Mach3 fame) I’m sure it will be a good product
At $120 I would need to make sure I was going to use it for something though.

Great videos! I left a question on your latest one. More a curiosity really.
