Luke11CNC Build Log ,I'm so naïve

[luke11cnc]

ok a up date
after prizing my son out of bed and then 10 min's later off his computer we made some progress
and did some work in the garage on the CNC machine

and here is the images of today's progress on the x-axis

we first (me) with the aid of pritt stick glued the printed templates to the 75x75 angle and then centre punched it, as image 1



after centre punch the template was removed and we then drill the angle out with a 6.8mm drill as in this next image and yes that is the young man that is building the CNC machine.



after we drilled the holes (long, long time and lots of oil)

we bolted the bearings to the angle as in this next image



after some choice words we finished and he went back to his computer, great I can get some work done (bless him, dad your drill is much better than the drill at school it would take hours to drill one hole, and we did 16 in 11/29 poor me)

But it was worth it just to see a smile on his little face

any way sitting down and having a coffee i thought how am I going to get two rail square?

this is what I came up with



and after some playing around with G clamps and guide it all worked out fine, smooth movement with NO binding



looking good



WHAT DO WE DO NEXT :question::question::question::question::question: :question::question:

I have one ball screw and the other one is on it's way and Jonathan has cut the support for them both

James and Luke the short one but never ever tell him please

looking good

Just what I was thinking :)

WHAT DO WE DO NEXT :question::question::question::question::question: :question::question:

Er...rest of the gantry? No idea really, I just did it in any order - gantry first and then the bed etc, but only due to space and it being the most interesting bit! I would get the ballscrews mounted before fixing the rails to make sure they don't cause binding.

I hate to mention 'health and safety', but I've often heard that you shouldn't wear a glove (or any loose clothing) whilst using a pillar drill as what if the glove gets caught on the chuck ... ouch

Jonathan,
you beat me to it. DO NOT EVER wear gloves when using a drill. If any part of the glove, even a thread, catches in the chuck it will pull your hand then your arm round with it.
The only gloves I ever wear are the thin nitrile ones so that my hands dont get oily. These rip very easily so wont cause you any problems.

I agree but

that is what they teach him at school, and I don't know any better?? what am I to do??

James,
you could always point them to this link

If you scroll down to the section on drilling machines you can read their advice.

I think you should complain. Surely they should know better? Even if the drills are not powerful enough to do a lot it's still just wrong. I approve that they do DT in year 6 (or year 7?) as at my school it only started in year 8... but we did go straight onto using the lathes and milling machines :)
The head of department reckoned first years were too dangerous!

Jonathan

they have gloves for this and that

smocks and boiler suits ( all with gloves and long sleeved arms)

and not once have I had to supply glasses we have to supply glasses for science
gum shields for sport and a full cricket kit including box and sun glasses even sun tan cream

I think I will inspect the DT department

James

[luke11cnc]

he's already had a year of DT and made a puzzle use a dremel and carved his name in MDF they are using drills, scroll saws, pillar drills and hand tools

I hope to turn him around and do things the right way and the safe way

I've heard it repeated by rote so many times that you shouldn't do it but so long as you wear the correct type they don't easily get caught. Also, if you don't put your hand in the chuck or bit then it can't get pulled in.

I've been wearing gloves with heavy drilling machinery for 22 years, as they are mandatory in my work. You DON'T want any fabric or stretchy palms, our gloves are nitrile-coated non-stretchy palms and elasticated back. With about 60 employees drilling every day I have never seen a problem related to gloves catching and our drill extensions are covered in stillson burrs.

I always wear gloves when drilling with my bench drill as I don't like getting my hands cut or burnt. For your lad, you could run the belts loose enough to turn the bit but slip if there's a foul-up.

Hello all I've been away for a long weekend but back now

I did add the new brackets before I went away but I am waiting for new bolts to arrive I should be ordering my drivers, break out board, power supply today and at the week end my spindle 2.2kw water cooled vhf.

I am waiting for some aluminium for a bracket (Jonathan) I will send you the drawing if that's ok, I will supply material if you just give me a price for milling it please.

next week end I will be buying the rest of the aluminium profile to finish the bed and gantry so with any luck I should be ready for wiring it up in October :heehee::heehee: I really can't wait to start playing with the machine :naughty:

I will post some more images this week and even maybe a Video

work to do this week
fit new bolts to brackets that Jonathan has made (twice because I made the drawing wrong (radius in stead of diameter, I really f#### up)) but they will be used some where
fit ball screw to one side, but drill and tap both side's
fit stepper motors to x-axis
finish supported rails
add bed support rails 45x60 profile

James and Luke:rofl::rofl:
