Re: Allowing For Bending Radius Folding 3mm Small Aluminium Sheet

Update :) I'm making an amplifier chassis using 2mm/3mm aluminium. The exact chassis dimensions are 14 inches x 12 inches. I'll be ordering a pre cut sheet from Ebay. As you can see the chassis has two folds, the front and rear panels. What I'd like to know is, as I'm folding two bends. What do the ...

Allowing For Bending Radius Folding 3mm Small Aluminium Sheet

Hi, Using a metal folder I'm ordering a 30cm x 15cm sheet of 3mm Aluminium to make a box shape but without the sides, as could be made on a box and pan brake. Um, don't think I'm explaining very well, but hope people will get the gist of what I'm trying to get across. Looking at the jpeg, say the sh...

Using Forstner bit To Drill 19mm Hole in Aluminium

A Forstner bit drilling a 19mm hole in bendable grade aluminium , would a Forstner bit be able to handle drilling a 19mm hole in 3/4mm thick aluminium perhaps even 5mm thick?
Thanks.

Re: Making Punch And Dies On The Milling Machine

I have no doubt that you can succeed in this venture, but it would pay huge benefits for you to get some experience in machining before attempting a project like this. I say this for one reason, and one reason only. Anyone can make chips, but it takes some degree of skill and talent to make functio...
