75 mm HAND WHEEL

[Lee Roberts]

This project uses a 12mm or 1/2” thick aluminum plate or round bar to create a hand wheel.

If using cutoff round bar material you may need to square it up in the lathe first. Drill through the center of the material with a 5.0mm drill and thread with an M6 (6mm) tap. This serves to bolt the aluminum to a piece of material that can then be clamped to the machine bed.

When complete the center hole can be drilled or reamed out to the size required. The file's provided will machine the basic shape, other details can be done manually to one’s own requirements.

The G-Code file to machine basic wheel shape using a 4mm slot drill and a pdf of the part are attached to this post below. The part is quite a large file and may take a couple of hours to complete, if a lathe is available you could also turn the wheel for a final finish.

This was originally provided by Roy over at www.diycnc.co.uk (http://www.diycnc.co.uk), He also has some other cool projects too.

Hi, can I ask what cad cam software you used to produce this part and post process it please?

[Lee Roberts]

Hi Chuck,

I got this project from Roy over at www.diycnc.co.uk so I don’t know what software he used sorry, I have updated the original post to correct a few things and I have also added a pdf as a technical document for the part, it shouldn't really be too hard to re-draw this part in your own favourite CAD program.

Will keep my eye out for your reply, would be cool to see you make this and use it on your machine!

If I may just ask a question Lee, why is the handle not in the middle of the solid part as it would be much stronger!

You could move the centre connecting web to the handle position.

Nothing to stop you designing your own.

[ptjw7uk]

Not that I would want to design my own wheel, just from an engineering point of view having the handle offset from the web could lead to a fracture as the rim will flex under heavy stress as did citreon sterring wheels in the 60's DS19.

That was 52 years ago, Fords have managed more monumental cock ups far more recent than that. :lol:

I may re-invent this wheel at some point :idea:

Nice!, think i would rather see the handle as a solid bar with no tapered fixing, with a dome/ball finish on the protruding end.

Maybe also move/rotate the 25mm radials on the outside of the wheel so that the handle has more material on its outside edge. Should keep Pete (ptjw7uk) happy also ;-)

What did you draw this up in ? solidworks ?

Admit it. You started this thread just so you could get that in, didn't you?

[Lee Roberts]

ok ok i hold my hands up :wave: yes i started this thread back in 2008 and now finally i was able to say it :tongue: :eek:

:toot:

Not sure I follow???

Hows this5508

[Lee Roberts]

Almost...

Like this for the handle see pic (more contact area for Pete :lol:).

Then swap the red with the green, so rotate your arc's around the wheel.

I like what you have done with the handle but no not what i was suggesting...

See my pic and look at the fixing point for the handle, you will see it has no taper to it yours looks fine though mate.

With regards to the outside arc's, i was meaning to move/rotate them around the wheel so that the widest part was inline with the handle, see my ruff pic for an idea of what i was meaning.
