Yeah, that's one of those thing i want to build since awhile. There's a lot of fun in it.

Trent. your worst bit of work as you called it, looks quite good to me. What method did u use for that.

Hi Steve. Sure it is. I am looking for parts that would give the precision for the job. If you have any infos please share. One link for metal parts (alu parts really) I found was: www.minitec.de

Hi All
Ioannis:

I am looking for parts that would give the precision for the job.

I have dabbled in building manufacturing CNC machines, the word that stands out is precision / repeatability , and for that you need to spend proper money. I know you are using precision in the subjective sense, but just look over at the hosted sister forum (no name ) and look at the problems that even a simple CNC can generate like the recent debacle over a “hobby” colinbus kit.

We know there is a plethora of sites dedicated to CNC but I have found that www.cnczone.com and its extensive forum always always worth a visit. In the UK automotion has been making a presence over the last few years at the big manufacturing exhibitions. They have a some reference books particularly “linear and rotary motion components” which is a handy start, they are at www.automotion.co.uk

Of course Wixroyd has to be listed for accessories.

In any event one main enemy is going to be vibration, the foundations of a plant in my opinion is of singular importance, you can spend hours farting around tweaking with dampers, braces etc, but there is nothing to beat a good solid ground flat base and if you can’t bolt it to a concrete floor then secure it to a pile of concrete slabs.


As for fascias, I sometimes use Quick-Mark which is the replacement for the 3M Dynamark, but if you are only wanting one-off prototypes, there is nothing to beat a photocolour inkjet print and a simple laminating machine. Use a laser or sublimation inks for UV stable prints, I havn’t tried it with a wax printer yet. Fix them with a permanent photomount spray, if you do suffer from possibility of curl then use carpet fixing spray adhesive. Sometimes I use my PCB layout software (Eagle) as the Artwork source, creating separate colourways in unused layers, very useful when rearranging components that project or are position critical through the enclosure/artwork.

Has anyone used these guys before

were you not asking for the UK and a cheap hobbit?

Last time I did this outof house was using Lasershape in Leeds on brushed stainles plates approx 350mm x 220mm approx £13 each for 20 units they will take a standard DXF file and use either water or laser to cut. They only have a two axis cutter so no bevelling. Then I had some of the units sent to a silk screen company in Colchester who printed it with a logo 1 colourway approx 50mm x 30mm for about £30. but I think we only sent 2 units off to them.

By the time you have the shipping costs to and fro and having to give files in correct format you might well be looking at using one of the array of products at somewhere like www.megauk.com. Give them a ring they are very helpfull they may even be able to put you in touch with a local UK based Hobbit customer of theirs.

There are a number of people doing the soldermask principle on very thin sheets of stainless and etching designs into the surface. Some of the business cards they produce are very impressive, just an idea........


oops got to go fast
