Wat type of cutter did you use for this. When ever I cut in Pine, then it turns out like crap, cause of the stringy chips. Or is that spruce that does this...
Hmmm, Pine here in Denmark, might not be the same Pine you have...

It is stain grade pine. I find that you have to run feed at little less and the spindle speed higher. I used a Freud 90 V bit, a Freud double flute straight bit and Onsrud up cut spiral. For the most part it will cut clean however being Pine there is always a small amount of finish sanding to do.

Not quite finished, still need clear coat sealer applied.

Almost Done

That looks awesome Pete, very impressive!

Very nice indeed.
I will put it on my 'One of these day's' list.
The list is long.

I have one of those lists too Al - snap! :)

I don't have a list, I have a Pinterest Board ;) Does that make me a tragic young punk. My wife introduced me and I love it. https://www.pinterest.com/generalrepairco/cnc-made/

While I do not use Facebook or Pinterest as I feel it uses up valuable time best spent elsewhere. That is a nice board you have Dale. It should be listed under websites that inspire here at the forum.

Mayan Haab crv3d, dxf and eps files in Zip format below. I removed all toolpaths since your tooling will be different.

Enjoy. :)

Top Coat Finished , on Flickr

Wow thats big! Looks great Pete, that smile says it all :)

nice work, looks pretty sharp...any details shots ?

Just what I have on my Flickr page

That looks awesome!!

Hey Pete,

you should put your flicker page in your sig on this forum (nice stuff there)

Thanks Fox. I have had it linked under my home page. Unfortunately this forum doesn't allow end of post signatures or I would have one.

Nicely done Pete, I bet painting it was a real pain in the arse.

Yes it was

Made an update to the machine. Will post picture after painted.

You tease...��

Painted. Pictures tomorrow

I know, I know..... not telling though :)

New Z axis!

It took a little while to draw this out. I stayed at relatively the same height above the Y car but have some new benefits to the Z. I used a 1610 ball screw with 500mm x 20mm round rails and bearings. I added push adjustments for ease of tramming. I had to make a nylon bushing for the bottom slot so I would have a pivot for front to rear adjustment. There is ±2° adjustment front to rear and ±5° side to side. More than is needed. The steps per inch worked out to 5080 and I can still run 500 IPM rapids. I did gain +2 inches to the retract height. One thing I found before was even though there was 8.79 inches from the collet to the spoilboard, adding a 2.5 inch bit reduced the ability to carve some larger stuff I had to turn away. Now I retract to over 11 inches using the 500mm rails so the bit is up inside the gantry during traverse to the tool change position. I was not looking for this but I worked with the parts purchased. I have full travel to the spoilboard with the collet flat on the spoilboard. Truing the spindle was less than 5 minutes both times. First time when testing and the second after painting.

Any questions feel free to ask.

Enough already, here are the pictures or click one to see them on Flickr.

Wow, wow, wow! Looks awesome painted Pete, this is definitely on my list of things to do to the MM.

Looks fantastic Pete!

I assume you used a section of large channel for the pivot mounting plate? Are all the painted sections steel?

Have you tried doing any heavy cutting, how well does the alumimium channel keep the assembly stiff in the forward/back direction?

ps - where do we download the cad files??? :D:D;)

Looks and sounds good.
A lot of time and effort gone into that.
I am sure that it will inspire others.
Well done.

Pete, nice job. I am interested in hearing about what you have done for the dust collection tube. It looks interesting. Could you post some detailed photos and provide some more detailed info?
Thanks

Pete, That is an Excellent Work of Art. I applaud you!

All painted sections are steel. Initial testing has been good so far. I will let you know as it is used more if any problems arise.

I will provide cad files of the design to anyone interested.

I did not have to make any adjustments to the tube up to the 4 to 6 bell reducer. What questions do you have and what would you like to know?

Thank you Tom

Very nicly done, inspiring work.
Thks for sharing and your generosity ! ;)

Excellent work as always Pete!
I really like the adjustments, something I would like to incorporate into my design.
As always, thanks for sharing!
Mark

First cut after upgrade. Cut from a piece of stain grade pine. 12" x 11.25" x 0.75". Model height is 0.74" and is 11" high.

Sweet...
So, this New-Z seem to work as good if not better !

For a moment i thought you had made a double extending z slide...

Robert, I may be bias but I honestly think it is better. My touch of probe is slightly off to the spoilboard. This left an onion skin. Before the cut was not as consistent. I was comparing to the Christmas one I cut before. The Z cut appears more even now. There were minute variations before.

Hey Pete, may I be the first to request the cad drawings? Thanks.

Pete, in my book your not being bias.....it's the being self reward & very satisfied with one own work....and good results ;)
I too tend to believe it may be "better"...... it's nicely thought out, nice materiel, nice build......but...cauz there is a one (but), it's the cost factor. Money can make "mechanical" make things ( among other) go better when those factor are inline.
Nicely done mate ;)
