If your other half has access to a large cnc and can cut most of your parts then you are in a good position to build your own.

It will take sustained effort and a good bit of time but it’s not as...

Splendid stuff :)
nice and warm inside

looking at you Y axis, the rails look unsupported which may lead to some problems over such a large distance
they will be like guitar strings when you get...

owch! sorry man... don't flap, if your tactical with your speeds you should be able to tiptoe around any serious resonance problems

if you are you looking to cut aluminium you may need the...

a touch of venom in my opinion, not aimed at any useful goal or conclusion other than to dismiss a fellow attempting to achieve a goal by "asking"


To "hot" for you, that's fine, I understand...

Merry Christmas you old bar-stewards :)…. What happened to the end of the world?... sod it, I guess we will just have to crack on.

Here’s hopping that you all make a million in 2013 or finish...

i was thinking more along the lines of irving with his bobble hat on playing forman while a slack hand full of us try not to spill to much concrete on his chrysanthemums ?

assuming your going to use a brush to clear the chips, plenty of WD40 and at a speed you can keep the chips clear
some alli will soon clog and snap your tool if you dont keep it clear

i tend to...

i personaly wouldnt get to bogged down in all the rocket science... make sure you get some tension in your balls and make sure your shaft cant easily rotate in the bearing bore (loctight the nose...

if i had this issue i would be pretty confident that a simple acetal leg running 45 degrees (ish) from my spindle clamp to the tip of my tool with a nice C shape cutout in the foot for chips to exit...

yep.... that'll about do it for me to :)

to right they do :)

not at all... thats just me being lazy...just try to put a "small" radius on your tip when your sharpening...

behave yourself :smile: we are all here to learn :)

it can be slow and painful cutting aluminium on a router but that tends to be a machine limitation but theres nothing stopping you cutting posh...

search for "single flute carbide" on ebay, they are great for plastics and do pretty well on aluminium and are cheep enough to take a punt on (£20 ish for 10 x 1/8" )

they have been talked about...

i would say it is worth splashing the extra cash..... however you need to do some lurking on ebay and bide your time so that your NOT spending £800 on rails n bearings... they do come up cheep from...

i got mine from here, you can stipulate the length etc then down load in various formats

no idea if they will...

Iv added another diy brushless spindle to my growing collection and thought id post my adventures just in case anyone was in the market for a quiet spindle with low rev torque for cutting plastics...

bad luck on the job man :sad:
cant really help you on the cetification route, most on here build their own machines and are self taught with CAD/CAM
im pretty sure some on here make a few quid...

bear in mind that the type of bearing blocks and rails we use in cnc are going to be pretty heavy to be lugging around in the field

it may be cheeper to buy carbon fibre rods, maybe 30mm or 40mm...

i forgot to say that you need to remove the mechanical link to the feedback pot in the RC servo to get it to run endlessly in which ever direction (and speed) you dail into the servo tester

for focus stacking i would just concentrait on camera stability and hand crank a gearbox attached to a 1mm pitch screw to drive it (backlash wont be an issue as you will only be driving in one...

this is a pan tilt head i made a few of years ago for stopmotion animation so hand cranking them was the way to go (motion blur has to be done in post production with stopmotion)

for the tracking shots i would use a simple RC servo with a servo tester to drive it and add a step down gearbox of some description... should be easy to build and cost £30/£40 ish for the drive side...

ahhh!! that sounds better :) i would have though you would be fine with that

if you have access to a lathe making your own spindle would be a cheep option.. easy to make one to fit whatever...
