Hi Mac,

Welcome aboard. I do not have the massive expertise that the majority of forum participants have, but I will throw in my two cents anyway. Have you considered a 5 or 10 to 1 mix of wood glue and water to seal up those edges? (careful on the amount you put on at one time). That MDF is one big sponge.

With all the 2 cents I am getting I will be rich in no time at all , my main problem was, I did not consider any sealer at all, and thats what killed my machine, I will give your method a try too, as well as the other methods the guys have shared with me, you are correct about the edges, mdf is really like a sponge, you should have seen my machine after the rain storm, it was puffed out like a marshmello but I really like using mdf for this machine I am re-making, it's very accurate and straight stuff (when dry)
Thanks for the comments JoeZ

Hi Mac

Just asking why are you going to made it out of MDF ?, don't get me wrong I use and like MDF but it's not always the best thing to use when making shop equipment

You may want to take a hard look at Birch Plywood, MDF just can't take any rubbing from any other parts, it just can't hold the edge, it will work great for a bit but then it will fail and all the work you put into will be gone and you will need to made a new one.

I have one of the new CNC type machines ( CarveWright Woodworking System ) and they are great but all the base parts are steel or Alum. and the trucks parts (Y & Z ) are moving all the time not to say anything about the router head that goes nuts going up and down....one note about the software they sale for the machine you are going to build, you will need to have some CAD background ,it's not a easy program to run.

BUT I do wish you all the luck in the world you, will need it on this project..

Bj

Hi Bj
Some people have made the rockcliff cnc router from plywood, plastic, mdf anything I guess that can be cut with wood tools, the one I made from mdf was running without any issues for almost a year, the slides are made from steel with bronze bearing runners, there are no moving parts that rub on the mdf,see photo the most popular control software these home made machines run from is mach3 from Artsoft mach3 control software which is amazing it is even used on full size industrial routers, milling machines and lathes, it can do more than what a carvewrite or compucarve system can do, will import files for full 3d carvings, circular interpolation (all three axis's can move at the same time, and up to 6) for cutting any complex shapes like a helix, digital probe , text engraving all for $160 I do not want to get into the technical stuff and do not want to write a commercial, as this is a manual wood router forum, but I guess some of it does apply, as the cnc machine is made from wood and is made with a table router.

Hi Mac

I didn't see the bronze bushing till just now , that should work

Can you PLEASE post a picture or two of what you have made with it
I sure like the way you have your show and tell setup on the web page you did a great job on that
I sure would like to see a helix,and some 3d stuff

I'm not the sharpest nail in the box but I think I would like to make one also.

Thanks for all the info so far and keep on posting
Pictures are worth 1000 words.

Bj

Hi Bj
Thanks but none of the pictures are of my machine they are other builders of the same machine I am building, yes I do agree he has been documenting the building of his machine very nice, I will post some pictures in the next day or so, all the cutouts are done, there really is not much to this machine, Norm would have it finished in probably a couple of hours or less (I really enjoyed his shows, what ever happened to Norm? ) it will take me at least a week.

Hi Mac

You said,,▼ did I miss read that one ?
"the one I made from mdf was running without any issues for almost a year"

Norm is still on PBS all the time, about 6 times per. week on channel 12 (Comcast/Colorado) I copy just about all his shows(DVD) I like Norm also
I don't think Norm makes most of the projects he has people set it up,clean it up,do it up, etc. that's what it looks like... no saw dust anywhere in the stage shop at anytime. look at his hands next time or to say at his finger nails.
But they do put on a great show

Please post a step by step on your machine.

Bj

Yes this is my second machine, the first one got soaked with rain and was ruined, it was left too close to an open garage door and we had a heavy rain storm about two weeks ago, if time permits I will do a step by step show and tell, if anyone is interested. is there a dedicated forum here to post users projects? I like Norm too since we moved to the country (satelite) I never get to see his shows anymore are they new shows or re-runs ?

Hey Mac,

How are you doing on building your CNC machine?

Just curious...
