Measure twice, cut once

Graham Meek will recognise this component, I had hoped to put the keyway in last

Now I know better!

Brian, I think you need one of those "Z" section keys that enter on one side and exit on the other

PS fixed your picture

Just machine half the keyway from the top, then flip it over

Neil

? ... picture looks upside-down from here.

MichaelG.

No its looking down on the stronger image and the lighter image is in the mirror along with whats on the wall.

The problem with teh picture was it was missing from the post

J

Oops ... I thought the machine head and the tools were just upside-down in the photo.

Jason

Why have you changed your Avtar from a very nice image of a traction engine ( presumably made by you) to, what appears to be, a picture of a slug on a red cabbage leaf? (...or has a bug got into the system somewhere? )

Regards

Norman

Thats strange, I'm still seeing my Minnie. I did upload one the other day when somebody had a problem as a test so looks like that has taken over. Will sort it out later as Wednesday night is shed night

J

PS its a bit of my Monitor engine

Gentlemen,

Thank you Jason for putting the picture on for me, it didn't appear as expected so well; found. Thank you for the comment on anodising, but it is a steel component with the details picked out in black marker pen to show rather than reflect

Michael. The tools are spanners seen through the mirror

Neil. That indeed was the recommendation by Graham Meek; I know I should have done it that way.

Norman I can't quite see what a slug has to do with this cock up, but the day continued in like vein to the point wher I closed up in disgust with myself! A better day tomorrow I hope

Brian

> I know I should have done it that way.

That was a joke, Brian! I assume you did the grooves that way, just the flip was in the wrong plane..

Neil

Neil,

Graham made a keyed jig to locate on the precut keyway, maybe he anticipated that sort of mistake better than I did!

I also put off until now making a guide for the keyway broach, the hole is 3/4 inch diameter so it nereds a new guide just for this job.

I know you were joking, but I shall hang it on the wall along with my other mistakes, the list grows!

Brian

It took a moment to see the problem then the penny dropped. Oops! We've all been there. My worst example of self inflicted shame was machining a component incorrectly on the very last cut (of course) forcing me to junk it, making a new one and then repeating the very same mistake. Fortunately my workshop has pretty good sound proofing.

Ok, so call me stupid, but whats the problem?

I'm not even sure what the round thingy on the bit of wire is.

John

It's the selector ring from Graham's screw cutting dog clutch, the radial grooves should mirror each other, which as the photo shows they do not, the mirror image shows the grooves are 180 degrees apart and the required key way will break into one of the grooves (which is not the main problem but the grooves being 180 degrees out means it is start again time).

Mike

I can't see what all the fuss is about! No, literally - I can't see anything in the OP's first post. There's just a blank space. I've tried iPad (PerfectBrowser), Laptop (Firefox33 + Linux) and the desktop (Windows 7 professional + Firefox33 and Internet Explorer). I'm busting a gut to have a look, 'cos it's something I do all too often! I'm glad to know it's not just me - although I do send my sympathies Brian.

John,

I think they must stlll be in the process of migrating to the new server.

... Quite a few images are missing, today.

MichaelG.

Yes there are some missing images that were uploaded yesterday, Neil has been informed

Michael Poole knows exactly what it is and the cure!

Ah well, back to swarf making

Brian

Migration has happened, but now the website has multiple issues, they are trying to sort them ASAP.

Neil
