Ferrex To Old Style DeWalt Adapter

[Onoff]

Just finished this for someone. My own design.

Uses the original yellow "tower" and DeWalt battery connector.

 

 

The new blades to engage with the Ferrex battery are from 9x1mm copper.

 

 

A 4 piece print; body, clips and wedge to keep the copper blades in place:

 

 

I could split the body into two, bolt together sections, to allow different batteries to be used with an appropriate printed section.

Very tidy - what nut inserts did you use and are they just press fit?

M3 heat inserts. I made the hole 3.75mm dia. Cut down a spare soldering iron tip, pop the insert on and push it home. Could likely increase the 3.75mm a tad as it pushed the molten plastic (in this case PETG) ahead of the insert. In this case winding the screws in pushed the dross out the other side no problem. Might be trickier with a blind hole. Printed btw on the Bambo X1C.

A total aside but my chippie mate had a load of 18V DeWalt tools that took the old, "tower" style DC9*** Ni-mh battery.

 

He upgraded to the new, DeWalt XR li-ion kit.

 

He bought an adaptor to use the XR battery on the old kit. Reckons using a li-ion battery on the old tools burnt out the "trigger" in a couple of the drills.

most of my dewalt is the old style but I've moved to the newer batteries to go with a couple of new tools. No hassles with the tools but the contacts on the cheap adaptors aren't great and can get a bit toasty and melty if you push things too hard.
