Yes, thanks Andy.  A long straight shank might be a plus, but I couldn't 
make ebay spit out such a well organized list.  The Tormach already has 
a 3/4" spud.  With the 3/4" spud I can still be pretty stiff if I have 
to drop it 3/8" to get where I want to do.

Anyway, the stuff is ordered, so the damage if any has already been 
done. ;-)  We'll see.  Hopefully no blue smoke will drift across the 
pond when it gets here. ;-)

Obviously I will accept as much as I can get.  The question of is the 
Tormach part enough will not be answered till it gets here.

The list will probably be advised, yay/nay in a few days.  Mail out of 
Kalipornia seems ever slower.

Done, waiting on LMS now.  And this time the jigs hold down bar bolts are 
screwed in straight as I drilled, and tapped them 3/8-16, right into the 
white ash of the jig, using the mill to both drill straight, and run the 
G33.1 rigid tap routine to tap the hole, but the tap drill was sized for 
about a 102% thread depth.  And found that the 1 horse motor, in low 
gear and in its present PID tune, was stalled by the tap from about 400 
revs if I tried to tap .5mm deeper than the hole.  That was good because 
I could hit esc, loosen the chuck and back the chuck off the tap shank, 
and remove the tap with a pair of vice-grips, leaving a good looking 
thread in the hole.

Then spent from about 16:00 to now, burning in one of those Lowes burn 
contraptions, about 300 lbs of old scrap from the workshop's and yard 
trash.  Some of it dated from the direcho that blew thru in 2010.

A fine mist is in the air, so that nice bed of coals will not burn 
completely, darnit.

I am with Jon on getting one of these tilt heads back into tram.  Its a 
meticulous pain in the back to get it to where I can set a dial against 
a piece of 1/2" A2 about 6" long in the 1/2" R8 collet.  The first thing 
I found was that it was whipping about 8 thou in the X direction when 
the Z was reversed, so that took about 4 full turns on the gib adjusters 
to reduce it to half a thou.  Then the drill rod had some rust, causing 
an ever increasing runout the farther the dial was from the R8, so I 
wound up running the spindle at about 40 revs & slapping the head with 
the bolts slightly loose, with a hammer until I could run it up & down 
about 4" with a center of needle swing staying within a thou.

Too fussy?  Maybe.  You guys tell me.

You cannot let enough tool project from the R8 to make that practical, 
Jim.

Some of this jig is 2" taller than the 1 by Mahogany being carved is 
tall.  The spindle brake, mounted on the quill housing makes it all  
about 5" in diameter, plus the brake pin sticks out in front by about 
3/4".  So I must have a fairly rigid 1.5" or more extension which it 
looks as if the Tormach 3/4 spud R8 to ER-20 adaptor will give me enough 
to work with.  It's at least 1.5" longer when seated in the R8 collet.  
And I moved the hold-down bar back from the work area about 5/8" from 
where it was before, so I am hoping that will  give me clearance so the 
nut on the Tormach tool adapter won't hit the hold down bar.

That makes you 32, Rick.  Too late for a back of ear drying towel & still 
too early for S.S. to kick in.  ;-)

I like being creative, and I'm not above doing something just because 
someone said I can't.  I may, more often than not, yell for help here, 
knowing that quite a few of the folks here have, like me in other 
fields, been there and done that.  And I find that putting the problem 
into words is a huge help in thinking it thru to a satisfactory to me at 
least, working solution.  Such was the case today, and I believe I have 
that problem under control.

I was rather surprised when the pointed 1/8" carbide round over bit 
arrived when I found its overall length was only perhaps  1.25".  So I 
am in essentially the same boat as when using a 0.125" end mill.  No Z 
room to do any 3D work at all.

[Emc-users] GO704's fat spindle is being a problem child.

[Gene Heskett]

Greetings everybody;

Thinking in electronic ink here...

Is there a quick & dirty but adequate way to extend the 2 most common 
carbide bit sizes in my collection in order to gain clearance between 
the workpiece and its holding jigs? Something like an ER8 that I can 
plug into an R8 maybe?

What would be a good google search term?  Or just hit Tormach's site.
Their ER20 adapter covers up to 1/2", and sells for $34.95. Tolerable 
good. And it looks like it would extend the reach of a tool by at least 
1.5".  Thats also good, gets the quill housing up high enough to clear 
the jigs. The 15 count collet set is $192, or the 30 count set is $372, 
probably more accurate than some of the others, but hey, I'm carving 
wood here.

Grizzly wants $317 for the whole 16 piece kit including adapter, South 
Bend brand.  Neither seem to say what the OD of the nut is and I've 
already hit the side of the spindle against this jig when it was on the 
toy mill, whose rotating spindle nose is 40mm.

But I hit a lick at LittleMachineShop. Tormach adapter & 3 collets, 1/8, 
1/4 & 3/8, for $72.95 shipped.  That will or should cover 98% of what 
I'll be doing.

In the meantime I can make a new holddown bar for this jig out of solid 
maple, and set it about 3/8" farther away from the tool travel.  And 
maybe glue on an extension to the flat plane of the front of the jig for 
additional workpiece support as some pieces will project close to 4 feet 
off the front of the table when mounted.

Todays projects. ;-)  Keeps me out of the bars don'tcha know. ;-)

[Emc-users] GO704's fat spindle is being a problem child.

[Cristian Bontas]

Hello

Have a look here for the sizes of the ER nuts (there are several versions).

http://www.aliexpress.com/store/product/ER-chuck-nut-ER-collet-nut-ER-nut-ER11-50-type-A-M-UM/506241_528850800.html

For ER 20 (the smallest that can take a 1/2'' tool shank), the minimum 
diameter would be 28 mm, with a type M nut.
So from your 40 mm spindle body, that would give you an extra 6 mm of 
clearance.

With the much more common hex-head nut, the gain would be minimal - only 
3 mm.

Plain old R8 collet in the spindle would gain you the most headroom, but 
you would loose your tool length offset each time you did a tool change 
unless the tool has a depth collar on it.
