Hi Guys, after having a lot of encouragement from reading and trying to learn the basics in building a cnc machine I have finally got the courage to go ahead with a build there is a wealth of information on this excellent site and I have not scratched the surface on all of the information that is needed for a build but with time I am sure I will get there
I only have one question that I need some help on and that is has anyone made a machine mostly out of HDPE its more expensive than 1 inch mdf but my main concern is the not quite so nice English weather damp and cold for most of the year I know you can seal mdf but the thought of making it out of something that is not going to absorb water, not rot and should be maintenance free I just want to get it right the first time around but not having no experience in HDPE I though I would ask the experts on this great site I have seen some posts where people have made some rail adjusters out of HDPE so I suppose my question comes down to this.
Would it be better to make most of the machine out of HDPE or MDf and what are the real pros’s and cons of both, thankyou in advance Paul.
