Search for “DIY Machinable wax” to find a number of recipes / instructions.

Guess we should add it to the wiki.... a special section at the top of the Materials page?

It's not super hard, it just takes a few hours and you need to set aside some equipment for the purpose.

These links should help:
eg whatever you melt it in, and the strainer... you won't be using them for anything else ever again. ;)

I bought one of these to melt it in, which turned out to be not great, because the heating element is directly exposed to the liquid wax/plastic mixture:

So, impossible to clean the solidified wax/plastic off it afterwards. :(

If you find something to melt it in, which doesn't have the heating element directly in the liquid, you might be ok to reuse for something else.

As a thought, if you're in the UK or EU, I can probably sell you some. I have kilo's of the stuff coming along... ;)

If you're in the US, this guy has made it in one of these:

I kind of wonder if a vacuum pump would be useful when making it too. I don't have one (yet), though likely will in a few weeks. ;)

Added a section on machinable wax (actually test cuts / materials) to the wiki: http://www.shapeoko.com/wiki/index.php/ ... FMaterials --- let me know if it needs any improvement or adjusting. I think I got all the references right.

Looks good. Probably remove the Quest deep fryer though... it's really a bad choice for heating the liquid with. Although it technically works, I wouldn't get it again (for this purpose). ;)

Side note - Just ordered the Kress today instead. ;)

More practise with Fusion 360, modelling potential approaches to a holder. Not redesigning the Z-axis plate yet. ;)

First, the way over-engineered approach:

Fusion 360's tools for dealing with imported mesh's are unusably poor. So, instead of using that for the boolean operation to cut out the Dremel holding section, that's being done in Meshmixer as the pretty-much-final operation:

Estimated print time for both pieces... over 12 hours, and about 1/4 kg of plastic at just 10% infill. Not optimal. ;)

Going for a more minimal concept:

That should lay on top of the existing aluminium mount, slotting nicely into the middle circle cut out, and bolting through the Z-axis plate using the 4 spare holes already in it. Estimated print time is about 2 hours, using a raft. That's an improvement. :D

Still need to figure out how to have an upper piece holder too for stability. The two spare holes at the top are so close together I'm expecting they won't be useful. Might need to drill some holes in the Z-axis plate, near the top and well spaced out or something. Open to ideas of course. ;)

Yeah, I’ve been considering a 3D printed mount for my Makita.

The other thing I’ve wondered about is why we don’t just make an L-shaped Z-plate w/ standard Porter-Cable hole pattern (answer: expense, hard to adjust, shifts router out too far).

Guess I need to find a chunk of 1" thick aluminum.

Yeah, more holes in the Z-axis plate seem like a needed thing for a lot of upgrades (I wish we also had standardized tapped holes on the mount).

Heh Heh Heh. For this mount testing stuff, only going with 3D printing because it's already setup here, and is easier/cheaper + more accurate at present than my current S3 setup. (My S3 is not at all accurate, thus putting time into a better spindle mounting system).

Would it be feasible to use some kind of thick plate, and have it accurately bent at the L? That should mean the whole thing could be created as one plate, then the fold done, to make the end result. (or is that obvious? :>)
