Part 006 one almost finished





This one is done, except for a hole in the end facing us. I need another one like this, though.

Part 0006 started


This part will require machining in two different setups. First I machined some counter-bored holes in a piece of wood ( using the Profile operation ) and finished them with Dad's pillar drill. I bolted this on to the table using the t-slots. I machined an area flat on the wood. I super-glued the Delrin to the wood. I am doing some profile operations with 6mm slot cutter. Unfortunately I forgot to check that the Y-axis had enough travel in the position I placed it. It hit the limit while rapiding to the outside profile. The part is not scrap. I will need to do it again, but machine an area in the wood with an island left standing in the middle to locate the part.

Part 0005 done

Dialog pictures

I extended the properties window to be able to have a different window. This can be in addition to or instead of the property grid. My example for cuboid just makes a window with a picture, but I hope to make some windows with controls ( edits, radio buttons, pictures, list boxes ).

Part 0005 first side OK



This works well. It is a bit labourious having to saw away all the wood, so it is flexible enough to peel off the Delrin, but worth it. Leaving 0.1mm on the depth is always a good idea. It doesn't take long to sand it to exactly the depth I want.

Part 0005 super glue

I think carpet tape would be too inaccurate. Also I don't have any.
Super glue seems to stick Delrin to the wood strongly enough. Also, I can remove the piece from the wood with my pen-knife. Now, can I remove the super glue with hot soapy water and a sponge?...

Leaving it to soak in the washing up bowl...

No. But I can sand it off and nobody needs to know it was there. I'll leave a little bit extra on the face machining depth, so I can sand it down to the required thickness anyway.

Part 0005 attempt

A daring attempt to not waste material. I wanted to do this one without needing tags.
It seems to go wrong on the above picture, where the two clamps can't stop the top edge lifting up a bit.The underneath of the arch seems to join perfectly, so the lifting edge went back to where it was when I moved the clamps. I might try clampless machining. If super glue works well enough, it might be worth clamping the Delring to the wood with super glue.
