Peck Drill
SPiN Racing:
TIME for an update!!
I have a slew of pics I put up on Imageshack.. so I will put them in. THings that happened over the busy weekend, and I just now have a chance to make a post with the detail LOL.. Or some of it.
OKEY Here we go!
(Yes Lots of Pictures) :worthless:
Chunk O Brass, freshly purchased from the Holy Grail... and since it wasnt a Drop it was $6.15 a pound for 1.5 Inch diameter. 1 POUND per 1.5 Inches. So yeah.. 12+ dollars for this 3" piece.. (OUCH)
But the guy didnt charge me for the cut, and gave me a deal on the other metal I bought so it all worked out.
Drilled a hole prior to Tapping it
Tap Tap anyone there???
That right there looks to be 1.5 or so.....
UGG.. me make ball that is square.
Chunk of threaded rod previously turned down for different things.. with smaller new shiny threads!
Hokay.. here we are ready to spin it up and make a mess from the brass! (Man that stuff is messy compared to steel and stainless!)
Zipping off the corner
Like cutting balsawood with a 1/4 inch die grinder!!
Getting there... need to slow down the speed of swings, and depth of cuts.
Coolant (WD40) not just for cooling... but to keep the samn Brass Sand from landing on my arms when Hot... I should tell myself to put the damn shield down.
Pretty Round I think...
Scotch Brite anyone? (about 1 minute or scotch brite)
Ohhhhhh Shiny!!!! about 3 minutes with the polisher.
OK now..
Need to make the hole in back larger so I can tap the thing with my new shiny 5/8-16 Tap :)
But there is no chart I could easily (im sure its out there) find to tell me the size to drill it to, so it would tap properly.
Sooo I bored it slowly larger until I had the tap in it, and the cut threads in the taper of the tap were just entering the hole. (This was like 15 tiny boring passes later... pun Intended)
Live Center.. Plus tap.. plus tiny wrench plus hand turning the chuck=Tapping away.
You can almost see the threads in that hole..
I forgot to take a pic with the arbor in it...
cause... well... I was very irritated.
The arbor is threaded crooked...... YES I was warned of that. It was crappily made. SO once it was screwed in it wobbles at the tang a good QUARTER OF AN INCH.
Its sooo mal-cut you can roll the arbor on the table and the threaded shaft wobbles around.
More to come once I have time to breathe!!

Brice of brass is frightening isn't it :jaw:
NickG:
Think the problem is at my end so no worries! :scratch:
Bernd:
SPiN,
Nice job on that ball truning. :thumbup:
My first ball didn't turn out that round, it was more of an ogive(sp?).
I like turning brass better, it doesn't have the curly swarf like steel does.
Hey, again nice job on that ball. By the way get yourself a Mchinery Handbook. In it are formulas for figuring out the size of drill you need for taps, plus lots of other machining info.
