John Rudd:
Ok, A little more progress albeit slow...more diy done today...SWMBO is laying the law down
I sketched up a few dimensions on how I thought the dog clutch was going to look...excuse the scrawl, I know it looks like something a 3 year old had drawn but I'm not into CAD drawing and it would take longer to do than machine the parts...
Also a picture of a piece of Ally bar 60mm long and 32 dia marked out for the dog's ears...cutting them will be interesting as I've never done this before...I found it easier to use the centre finder to draw the radial lines on the end...
Any advice chaps before I waste mor metal?
Are you keeping up so far? I hope I aint boring you folk...( no pun intended...this is a machining forum after all )
More to follow...
bogstandard:
Wrong John,
This isn't a machining forum, it just looks like it. It is a project forum, which is slightly different.
Your sketches are fine as they are, except you need to upgrade the the now web famous Bogstandard C-o-C (Crap-o-Cad) system.
The upgrade consists of black felt tip rather than ball pen or pencil, it makes it easier for people to see, and for the deluxe system, colours can be introduced when you have mastered the basic version.

John,
Take a 10mm milling cutter and run it straight through the work off set by 5mm. (so the outside of the cutter runs through the centre)
Turn work 120 deg and do the same again,
Turn another 120 deg and same again
You will now find your dog matches the part on the miller.... :thumbup:

Darren,
I thought I was reasonably versed in machining but this is somewhat of a challenge...A faint heart and all that..I'm not put off but a little confused by the statement you made...
Here's what I think....
I have six radial lines, if I align the outer edge of a cutter with line 1 and cut thru to centre, next mill thru line 3 and so on...Right?
Thing is I'm having to do this twice...so accuracy is the requirement of the day..I'll make the first then machine the second to match..
Good so far on this then ?
Darren:
John,
I think the way you are trying to do it would be quite difficult.
The way I have suggested you only have three straight cuts to make, each at 120deg.
It's very simple to do once you understand the results it will give. Accurate every time.
I'm not sure how else to explain the method, anyone else wanna have a go?
