Jouter jig for bevelled sections

[colinc]

Hi, a lot of my woodworking lately is aircraft work which often means machining quite small sections, sometimes of considerable length. However, I have a Scheppach planer/thicknesser which copes admirably most of the time.

However, I now need to make some sections which are chamfered on one or two faces. The stating sections are only about 3/4" square but 12ft long. Obviously I could plane it but am wondering if anyone has any ideas about how to approach machining this bearing in mind that accuracy is important.

I suspect that a spindle moulder with a tiliting head would be the answer but I don't have one.

I do have a substantial router table and a horizontal router table so perhaps some form of jig?

Ideas appreciated,

Colin

Colin,

if the chamfer aangle you require can be matched by one of the "dovetail" bits or similar, then you can run your work flat on the table.

A "tunnel" style fence covering the bit area will ensure the work is in good contact with the bit.

You could make a false bed for your thicknesser at the angle of chamfer you need and feed the 3/4 stock through guides on the false bed to do the cut.

The trick for doing long lengths is to keep feeding the wood all the time to avoid burning.
An (capable) assistant is invaluable if you dont have a power feed.

I wonder if adapting a sanding drum without the sand paper in a cordless drill might help?

Hi,

at the moment my thinking is going in the same way as Jon's, using the thicknesser.

If you have thicknesser, chamfered faces are a breeze. I have a jig for thicknessing glazing beads. It works perfectly. You are welcome to come over and see, I'm in Beeston.

Thanks Steve,

That would be great. If you would pm me your phone no. I'll give you a call back to arrange it - I work just off the A52 in Derby so only 20mins away.

In my opinion Jon has produced the correct answer. I also had some experience refurbishing executive aircraft and it was in this time I realised that we were not getting the full benefit of the use of the router and I have been developing these new routing techniques since. In my case it was a 'need to know' so that I could complete the assignment given and as there were no published material around I had to introduce my own techniques. It was some of the most interesting years in my cabinet making days.

Tom, am guessing that Steve has something similar and hope to get over to see him in a couple of days.

Doing woodwork on aircraft would be the ideal day job! best of both worlds.
