3mm radius on Aluminium Sheet

I have spent a couple of days trimming and making the parts for my centre console on my cars interior. I have made and sewn both the Handbrake gaiter and the gear lever gaiter myself as well as the metal trim to go round them. Looks pretty good so far.

I have made some metal trim (to go around the gaiters) from 3mm Ali sheet and polished them up but I don't think they will pass the IVA. Does anyone have any ideas how I can put a radius on the parts? I was going to just get the angle grinder out and bevel the edges with a sanding disc but there might be a better way?

Can you get a metal cutting router blade and router the edge?

Not sure if they even exist.

If not, when I made my trumpets I hand ground them with a dremmel and then filed and polished.

A good hand file would put a 3mm rad on ali with little effort.

Only needs to be blunted if it does not project from the surface so just take the edge off with a block and 240 grit

You need to use a file, use the draw filing method and dust the file with talc.

I am not sure metal routing bits exist. I have never seen one. The parts stick out 3.5mm from the surface so they will need a good radius on them.

Any of the carbide router bits will cut aluminium without any issue

As suggested a tungsten carbide router cutter will work (I did the tunnel trim using one) using several passes. However on such a small work piece I'd use a file.

I actually prefer the sharper edged look of it now and I have some suitable U-trim. This could work methinks. Cheers

I used a belt sanding table to radius the edge of my handbrake surround , the gear lever surround was done in a lathe

Get a big grommet. Turn it ouside in and fit it to the part. After IVA throw it away and put the shiny bit back on how you like.





If it looks wrong it probably is wrong.

File, then emery paper from 240 to 1200. You'll have it done in an hour, it's how I did mine. Ally's pretty easy to shape by hand.
