How to create accurate round ends

[DaveTTC]

Sorry Ian did not get pen to paper. Had a crazy arvo / evening. Will try to do a sketch first thing in the morning. Well let's say I'll try before 8:30

G'day Ian

Hope this explains my idea



You may need a sacrificial table for your disc sander to put / nail a pin into.

Your jig starts with the wood almost flat against the sanding disc. You rotate it to to just past 90º, flip the work and do the other side.

With a stop for length and a fence for width your pieces should all be identical.

Hope this helps. Either way love to see what you finally decide in the end

Dave,
I went with the Chris/Ian method of using a bull nose router bit to create a rounded end on some wide flat 19 mm stock, which I then ripped into 11mm strips.

Worked a treat, as would your suggestion, but since I had the necessary equipment I didn't see the point in building a jig.
However, my approach would only work if you had the correct radius router bit, whereas your suggestion would work for any required radius.

The first picture shows a bit of scrap pine I used as a trial. I used some scrap Tassie Oak for the job.

As I said, I got a bit obsessive over this but I did want a nice round and even finish, and that's what I have achieved.
The project was to build display stands for some small radio controlled yachts.
I have attached some pictures.

You may be interested to know that there is not a single nail or screw and no glue was used thus far.
I haven't sanded anything yet as it's just a prototype at this point. The entire thing is held together with just dry fit dominoes and a couple of 6mm dowels for the pivots.

Thanks everyone for your input

Ian

As usual there's more than one way to skin a cat and a good result in the end, and I learnt something as well.
