Puzzdre, I guess the guilty one of your "accident" was the vice.

Think of it: When you handholded the piece, any unwanted sideload applied to the tap simply tilts the part because of the soft holding. With the part firmly attached to the vice all sideloads are flexing the tap.

Even if you buy the most expensive Taps the situation is the same, it could be harder, but still brittle.

Puzzdre · 11-20-2002, 02:15 PM

It did crossed my mind that when I was holding the piece in my hand, movements of hand compensated the sideloads on the tapper, but today, before I started to tap the block, I tapped two more holes in the same piece of copper I tappered in hand, just to 'get the feeling' and see what happens. Everything went smooth. I was more careful, and advanced slower when I was tapping actual block than when practicing on that scrap piece.

You could be right though, I'll try again tomorrow both, in the hand and in the vice.

Yeah, no quality of the tool can compensate noobines in using the tool, but these I bought now are just a little more on the quality side, and ofcourse, no warranties that I won't break them too.

Thx!

if this ain't a hobby, then what is???

anyway, welcome to the club of workpiece spoilers puzzdre.

what can be learned?
-when u have a series of different jobs to do on one workpiece. the job that is most prone to failure and fux0ring up your workpiece, you do first.

so in my blockmaking career, from now on
1)sawing up the workpiece
2)lapping both connecting sides
3)tap the holes
4)....

anyway. is there a concensus on tapping? better to use no vice and just try doing it by hand? somehow i have the gut feeling that the vice is a bit better. i broke my tap when using no vice, whereas the succesfull hole i used a vice.

like bigben says, i thk WD40 will have a huge impact on lowering the rotational flex on the tap (is what killed mine). i don't thk sideway flexing had to do with my accident.

good idea, I should print it, with large bolded font if possible...

Thank you! I just hope that the number of the spoiled workpieces won't make me vicepresident, or worse...

g.l.amour · 11-20-2002, 04:40 PM

dammit puzzdre, there's nothing that gets you down now is there? ;-) never forgetting the humour to it all.

i can tell u , i was mighty pissed for a couple of hours after fux0ring up my workpiece.

Puzzdre · 11-20-2002, 04:51 PM

It's easier this way. Several yrs ago, I would throw the block, the drill press and the table down the balcony...But then I'd had to go down to pick all that mess up, and see what can be repaired of the broken tools.

Sure, I was pissed off too, but having the federal reserve of copper and still some money for the tools, just decided to drop it for today...Saved my PC's life several times that way...

Humour is the best way to tell the people (and to yourself) how pissed off you really are, and what a stupid and silly situation you are in so we all can have a good laugh...maybe...:shrug:

/edit/ Jeeeez, just re-read that, sounds like a clip from the 'Return of the Confuciuss' son part two...I must stop doing that...

#Rotor · 11-20-2002, 05:38 PM

hehe, and once you get past the " break the tap in the firts hole" syndrome, and you go forth and become rather proficient at doing it.... watch out for the last hole..... it will get you every time.... just as you are thinking to yourself..." I'm getting good!!!" SNAP

g.l.amour · 11-21-2002, 03:21 AM

well, i got 6m of copper now, and i still got pissed because i would lose 2cm of copper out of braking the tap. thats just the way i am. i had to move heaven and earth to get that damn copper...

Puzzdre · 11-21-2002, 06:41 AM

Thank you #Rotor!!!

Now we must figure the way of tapping the last hole first...

g.l., it's not just the copper, it's (IMO) all the bloody effort, time, money, tools we lost... If I imagine that I ruined my last piece of copper, I would take a month off of making the block...but now...

Imagine tapping the soap. That's the way it was today...

Good tools, and WD 40, I merely twisted the bloody thing, it all went smoooooth... Like it was tapping itself, me just standing there looking pretty...

If I didn't have yesterday's experience, I would never believe when somebody told me the tapping is PITA. NEVER. Good thing it happened like that, cos' now we now to go slow and buy the GOOD tools, cos' result is more than beautiful:

Puzzdre · 11-21-2002, 06:44 AM

There is still a gap between the halves cos' I didn't clean the mess in between, and didn't screw the halves all the way...

Man, I'm I satisfied!!!!!!!!!!!!!!!!!!!!!!!

here's the top view:

Puzzdre · 11-21-2002, 06:46 AM

Oh, yeah, I forgot:

YIPIIIIEEEEEEE, HUBBAHUBBBAHUBBBA, GOGOGOGOGOGOGO, YESYESYESYESYES!!!!!

g.l.amour · 11-21-2002, 07:24 AM

U DID IT!!!

i'm actually feeling proud. u r the last recent student to pass his metalworking crafts, finals in WB-building.

rox

say puzzdre , i got myself a tapping set m4 (damn another 20€)
3 stage; only it doesn't say which one goes first. there's one with 2 rings engraved on the shaft; one with one ring on shaft, and one with no ring on shaft. sounds familiar?

Puzzdre · 11-21-2002, 07:36 AM

Thank you, thank you, thank you!!!

Yup, sounds very familiar, in my set one with one ring goes first, two rings second, no ring final. Try to look at the 'blades', one with most blunt blades goes first.

And yes, don't forget the WD 40. I didn't try without it, but think it helped a lot.

Didn't tried without the vice either, it went too good clamped...

Wish you same luck as mine!!!

g.l.amour · 11-21-2002, 07:47 AM

thx, i already thought those rings were some sort of common tapping language. tonight da g.l. is going in for the kill on his both halves. the wd 40 is ready. both halves are lapped. take the time to do it good.

so basically puzzdre,.... u r almost ready!!!!

cheers dude

MadDogMe · 11-21-2002, 08:03 AM

I used to buy cheap tools, but they wear out so quick!, cheap socket/ratchet sets allways shatter(sockets) or the teeth on the ratchet 'go' so it just spins or clicks past when you aply pressure. hacksaw blades snap or blunt on the second pass. drill~bits last for 3~4 holes. power tools go 'sloppy' real quick. pliers go wobbly and loose their cutting edge and serrated grip. screwdivers!!, oh god the screwdrivers that last two turns then loose their 'key', and so on. the only cheap tools that work OK are Allenkeys!!(if they don't rust in 5mins)

. now I buy the best I can afford, and buy it once...
PS, anyone got a pair of curclip piers over 6months old that did'nt cost $30+/£30+?

...

sorry about the sermon, but I hate cheap tools. that little stamp saying 'Made in China' gives me little faith in 'The Workers Paradise'!

...
True throwing money at a job won't help if you hav'nt developed the technique, but it goes a long way towards being forgiving of 'teething(tapping?) troubles'

Those 'one tap' taps are OK for Alu/Alloy or plastic/plexi ect, but you can't beat the three tap sets, think of it as a two~thirds less tension on the tap with each one...

I'm glad you're getting there, it's nice to see someone happy with work they've done with their own hands...
