Guess we should add it to the wiki.... a special section at the top of the Materials page?
In the UK, I've been getting the Paraffin wax from here:

http://www.maragon.co.uk

They're a lot cheaper for small quantities than Amazon or sellers on eBay, and the items generally turn up 2 days later without hassle. For larger quantities (25kg and above), this seems to be the best value, and the seller has a good reputation:

http://www.ebay.co.uk/itm/141306759228

I haven't bought from this seller yet, but intend to.

Sourcing small bulk quantities of LDPE/HDPE has been a bit more difficult so far. Emailed a few plastic suppliers over the previous week and a bit. Only one has responded:
Thank you for your recent enquiry, we are able to supply HDPE/LDPE in pellet form.

Minimum order quantity (MOQ) 25kg of either material.

Price - £2.40 per kg plus vat.
Delivery 3 to 4 days.

Carriage and payment terms to be agreed. All prices are per kg plus vat.

I trust the above meets with your approval. However if you have any queries please contact the undersigned.


Kind regards

Asked them about postage cost for just a single 25kg bag of HDPE pellets, shipped to my house (UK based):
Shipping would be £12.00 plus vat via Parcelforce.

Kind regards

Response time was within about 2 hours, which isn't bad at all. Costs seem ok too.

Just noticed the Kress website has dimensional drawings:
That should simplify things immensely. :)

Finally created working upper and lower mounts for my dodgy Dremel clone. It's taken several iterations to get them "just right", so they fit solidly yet don't block access to anything important.

Sorry for the equally dodgy photos. Older camera phone, and it's dark outside. ;)

Will post the STL's, Fusion project links, and some screenshots in a few minutes. Waiting for the Kress to turn up. UPS should have delivered it today... but haven't. No idea why. :(

Tried attaching the .STL here, but the file size is too large. Even when compressed. :( It can be grabbed from the 'Fusion project file' URL above though. :)

When the Kress finally arrives, I'll adapt these for it, then probably start experimenting with materials. :)

Wouldn't it be better to arrange things so that the plastic mount is under the aluminum one and the cutting forces push the plastic up into the aluminum?

Please look up the specific Dremel clone you have and either let us know or post it to the wiki.

Possibly. Hadn't thought of that. :D

Let me think on it. That being said, so far this combination is solidly in place.

I'm now seeing the issue other people have mentioned, of there being play in the Z-axis plate itself. Not flexing of the plate as such, but the bearings aren't sitting super tightly against the Z extrusion, so there's room for movement between the bearings and the extrusion. I've adjusted the eccentric nuts as far as they go... and they don't go far enough to fix it. :(

It's this model: http://www.maplin.co.uk/p/170w-variable ... -set-n17qn

Seems pretty reliable so far.
