I Needed Some Collet Racks

"Those flat pack designs look nice. Have you used plastic or wood? How do they compare?"

Sorry Pekka, you've lost me there  :scratch:

The collet racks are CNC Plasma cut out of 1.2 mm mild steel on the CNC Plasma Table I re-built in this thread:

I am sorry...something lost in translation.

Those plasma cut parts looks nice and they are falt when they come out table. "flat pack" like Ikea flat pack htat you need to assmble yourself. In this case ou bend them. My imagination just running amok you churning them out, mailing them on flat pack and end user bending them.

I have been trying to deside between materials. My first instinct is wood...your's sheet metal. I was just wondering if you tried wood or plastic before. I am using small plastic containers that are actually pretty good. They dont't make best of space in my tool chest, been thingking of augementting them with wood/plastic/steel ER-collet racks.

Anyways compliments for getting the process really fast and right from CAD to plasma table. Well done.

Pekka,

When I sat down to draw the rack I had initially intended to cut them in plastic using my CNC laser engraver, but then realised that I didn't have enough suitable plastic in stock, but I did have a full 2.5 x 1.25 metre sheet of 1.2 mm Zintec mild steel. Actually I think the steel is probably a better choice as the plastic is too flimsy.

4 mm plywood flitted though my mind briefly, but I've had bad experience of tools in wooden racks rusting where contacting the wood - presumably it retains moisture.

PekkaNF:
Thank you. I thoug you have tried/thoght this out.

I am not sure if I like the plywood here, least it should not have any oak or any corrosive wood in the mix...I was briefly thinkking of making a little plug, and use vacuumforming to make small recesse, that would guide hole saw....but I really should do proper job and use milling machine or make a jig for drilling. Bit shape to plastic and it would not be overly bendy?

If I would go for steel sheet, I should use punch for holes. Your method is more elegant.

Now when I started out making these racks, it was purely to have something to use sorting out the collets, but now I need somewhere to keep the set that I'll retain for my own use. Conveniently I have a two drawer cupboard / worktop unit that lives just where my CAT40 / DIN 69871 tool holders live, and the drawer contents could be put elsewhere.

Less conveniently the drawers were an inch too narrow  :bang:
