Hubs, Spokes and Rims Templates
With all the posts here recently about hubs, spokes etc, I've updated the hub-spoke template calculator on blocklayer.com
http://www.blocklayer.com/hub-spokes.aspx
It now draws a full scale diagram of the wheel complete with hub, spokes and rim.
Change any measurement (hub OD, Rim OD, Rim ID, Spoke diameter, number of spokes etc) and it redraws the scaled diagram.
Add or remove spokes to see how (and if) they fit around the hub.
It also draws circumference templates with spoke holes marked, for hub OD, Rim ID and Rim OD.
Print the templates (at 100% printer scale), cut and wrap around hub or rim to mark the spoke points.
Are there any other wheel related calculations or templates that would be handy for wheels?

Very nice and thank you. I use your site. This makes it even better.

I used your template this morning. I am making spoke tires, instead of wagon wheels. It worked perfectly to create a template for the rim, hub and spoke spacing. The only thing that could have made it nicer would be if would allow me to draw the I.D. and and O.D. for the tire. This is not really of great importance and probably not worth the effort to add those dimensions as an option.
I really just wanted to let you know I used it and it worked. Well it worked once I found the setting for my printer to make it print at 100%! That is an operator problem

Thanks PLD
Good to know it's working in real applications.
I've added a 'Hub Inside Diameter' entry, and a 'Draw Centre Lines' option to draw single centre lines to the outside of the rim.
I'll take a look at adding the tyre, but it might just over-complicate it too much.
The 100% printer scale is the hard part. Printers all seem to have different ways to set the scale.
.... Funny how we spell differently. tire ~ tyre and center ~ centre. It's a bloody nuisance really, with Metric and Imperial versions needing different spellings on blocklayer.com

Like I said, probably not worth the effort. The only advantage for me was to see it I had decent proportions between hub, rim and tyre (my American spell check on the my computer says that is misspelled). What the heck does it know anyway. I just used a compass to draw the OD of the tire to see if it all looked proper.
I had to start using metric when I was building a crank organ. The plans came from the U.K. The more I used it the more I liked it. Use it as often as possible now.

Turned out to be pretty easy to add the tyre (the tire also)
So now, if you enter or select a 'Tyre Height' (also a 'Tire Height') measurement greater than 0, it will draw the tyre (and the tire).

Will, thank you. Glad it wasn't much effort spent.

Well thanks again, Mr. Blocklayer. I used your site to print a picture of the wheel I am trying to build. I glued a cutout of the wheel on a block of wood to use as a pattern for my wheel. I'm using a jig I built on my drill press to hold the blank and index the holes for drilling. With the "pattern" I made for your site, it showed me I had some problems with the indexer I made. My holes and the spokes on the pattern did not come out quite the same. I to a mic and checked my indexer and sure enough I had two index points that were a hair off. Well actually one was almost 1.50mm off. I'm in the process of making a new indexer wheel.

Thanks BL will work in future for spinning wheels also
