8x4 Wall Mounted; Upright ply cutter

[Sven]

Very nice to be able to look at something different being well executed!

Nice, I'm new to the field but interested in making a machine one day, may I ask are those rails or ball screws on the yaxis? i really like this design and would copy it if you care to share where to get them? and based on my logic i would say they are rails, so where do you plan on mounting the ball screws? or whatever would drive the y axis? thanks!

Just one question - doesn't all the crap fall into your X axis bearing,

YEP!!!. Im working a anti-gravity machine.... or... mounting it upside down on the roof!...

Seriously; The extraction system will have a bottom rail to catch any falling dust.

my greater worry is the x bearings being used on their side...

What size of steel profile was used? Whats the total weight of the machine? Did you thread the profile for the connections or the bolts are pass through?

* 60 x 60 x 6 and 100 x 60 x 6
* Yep threaded hundreds of holes (got w*nkers wrist!)
* I Dont believe any "nuts" are used.



Nobody has pointed out any faults?? I was expecting a wooping.... this is only techically mk1... mk2 Il learn from the mistakes on this one.

So; il be honest.

1.) The biggest mistake... I should of had the ends (both) of the X ballscrews threaded; so I could put them under tension. They do sag a bit under their own weight.

2.) linear bearings being used on etheir side? X???

3.) The Z movement is way too much... it probably only uses half of the travel available (so unnecessary weight on gantry)

4.) really needs twice as many bed support braces. The distance inbetween them in launghable... space for twice as many

5.) No water cooling yet for spindle in video

6.) No emergency stops; panic buttons etc

7.) Need to add proximity for auto-square; but where I had mounted the brackets didnt account for quite how tight the fit into the room would be. Il have to re-think.



Now thats out of the way; fitting a really noisy roller shutter door to my workshop/garage (just to wind up my new classy neghbours), and to allow me to squeeze my van in.

Im then spraying van; in workshop (old vw camper)

once thats gone; take delivery of my new bridgeport mill!!!! ssshhhh dont tell misses

then start building my new machine (like this one)

Where would you like me to begin!. . . . . . Only Joking mate for it's intended purpose of chomping ply it will be fine.!

As your about to findout going vertical is great but there's a few areas that need protecting and designing around.

Z axis one area as the crap will settle on the top edge and build up so make a cover or angled guard.
Also in your case using rotating nuts at top then crap will also fall into the bearing housing so cover that ASAP.

With lower bearings then you (know whats coming here) throw the crap away and get the real thing.! (thou that will test how accurate the frame is.!!)
For catching and moving crap Make an angled slide that extends from bed to just below gantry then crap falls over the rails not onto them. Put a wiper on edge and it will wipe the gantry plates.

I would have have put a slight angle on the machine rather than being 90deg as it helps with holding work and stops large sheets or pieces faling forward.

Keep up the good work but slow down a little rushing abart will kill ya.!!. . .

Just like the last build, a very useful source of information and techniques. Probably learnt more from your last two builds than 90% of the other builds on here.

i bet you spend half your time beating off people wanting builds done especially in those sorts of timescales.

thanks for the time that you have taken to provide REAL information and show what is possible if you do not get bogged down with techno crap.

The time and thought you invest in a machine=the result you can expect. If you are happy with that...

KC, you outlined at the begining what you expected of this machine, and I am sure that it will perform exactly as you wanted. I think that you invested wisely with your time and thought, and that you should have every reason to be happy with that!!! Well done again. G.

Who's that having a dig at Silyavski?

[Clive S]

Well, I am sorry but I thought it was a bit snide ..Clive

I hear what you are saying... I'm just pleased to see someone applying some common sense knowledge and experience, to produce a useable machine in a very short timescale. These are my views if people disagree then whatever.

Personally I think that kingcreaky is quite an inspiration.
