Re: Photobucket alternative. Was: Painted Myself Into a Corner Again
That’s very interesting news. Last week I received what I thought was a phishing email, purporting to be from Photobucket, asking me to upgrade my account because I was was using it for third party hosting.?
I dismissed this as a scam and checked the adverts that were linked to PB hosted photos and they are all still operational despite “PB’s” advice that they would remove this facility unless I “upgraded”.
So, it would appear that this isn’t a scam(?) after all?
Good advice from Ian, thanks.

Hi,
Wait awhile before going for a new photo host.
Like you, I am disappointed with the recent changes in Photobucket terms and condition which require me to pay an annual fee if I want to carry on using the site as I have been doing for the last five years or so.
Photobucket have really upset a huge number of their users and there are a large number who are looking to 'jump ship'. ?I'm sure that an alternative host will step in and grab the disenchanted membership by offering
the features that Photobucket has removed and also providing a 'one click' transfer process to import all your Photobucket content - 'io groups' did exactly this in response to the concerns over Yahoo groups
Give it a month or so and then choose.
Personally, I would rule out any provider who requires you to 'sign in' to view content as this is an inconvenience to others viewing your photos. ?This eliminates Facebook, Flickr, etc
All the best,
Ian
?
BTW, any recommendations on a good, free, photo sharing site.? I originally went with Photobucket based on recommendations from this group.? What's the current fave?

Re: Painted Myself Into a Corner Again
"You just need to dial it in so the turned section is centered & parallel to the lathe bed." That's the part I was wrestling with.? Would it work if I put the TS center in the center drilled hole and set my DI close to the chuck and centered the piece.? Or, would I still have to set the DI near the end of the piece to make sure it was aligned.? Still a little hazy on this.
Short drill might work.? I could keep the current set up (haven't broken it down yet, pending advice from you guys), put my steady rest at the end and drill part way in with a short drill.? That would create enough room to get my standard length drill in place.

You just need to dial it in so the turned section is centered & parallel to the lathe bed. Drilling from the TS will center itself; you might prefer to start the hole from the end without the center hole already drilled. Or, after dialing the piece in, check to make sure the existing center hole is actually still on the axis of rotation.
You didn't mention the hole size, so there may be some other options. The easy one is getting a set of shorter drills. Twist drills come in 3 standard lengths; jobber, screw machine & taper length. Jobber are the commonly found ones, screw machine are shorter, taper length are longer. The sleazier approach is holding a drill in a carriage mounted holder by clamping down on the flutes with a piece of brass tubing to protect the flutes. If you do that, you'll appreciate that its such a nuisance to set up you'll be inspired to get a set of screw machine length drills ;-)
If the hole is big enough, it's also possible to drill it as large as possible with whatever size drill is short enough to fit on the lathe & finish by boring to size.

Re: Painted Myself Into a Corner Again
Yes, centered and faced off square on TS end.? I won't try parting off a 2" diameter piece - instead will cut it off on my bandsaw.? No reason I couldn't drill from the end opposite the center drill.
So, I would be using the faced off end to "square" the piece up against the face of the chuck?

Assuming the piece is centered and faced off square, can you part
it off, turn it around in your 4 jaw and drill it from the other
end??
Chances are the center drill is smaller than the finished hole
and the hole doesn't care which way it was drilled, once it is
drilled through.
If that works, facing off the parted end (which is now facing the
tailstock) should finish the item unless I missed something in the
description.

You need to use the DI in two places. 1. on the park very near the chuck and 2. on the part very near the end.
Maybe a little plastic faced hammer could be used to adjust the DI reading near the parts end.

Works silly well - better than I would have imagined. With the Arduino/Anaheim Automation stepper/driver combo I can step down less than a mil using microstepping - what the toggle switches set - see the vids on that page -
Solid as all hell too.... I can ramp into a cut and it stays at the depth I want. With large cutters it's the typical "small mill - big cutter" vibe (you can see a bit of it on the DRO that reads down to 0.0002 [DRO PRO mag thing]) but it just plows thru - even on mild steel.
Even with the extended solid column -
I did the 2" solid column mod and sent the pics to LMS - they now sell a 2" riser block like what I made.
The thing is just solid... well, as solid as a little mill can be. And I use it a lot for my day job, doing silly I should never even try on a mill that size.

The design I like better places the screw on center line and almost
touching the existing rack. The head's weight is basically hung off the
stationary screw. The screw does not turn. A motor is used to rotate the
nut. I think the overall design is simpler.
People are getting better than .001" with this kind of setup.
Searching around I find a photo of this design here. It lifts from the
center of mass. Disadvantage is you need a full height ceiling but likely
a non-issue for most.

Allthat said. I have a simple DRO mounted to the z-axis and it is accurate
to .001 and reads to .0005 if I use the gib lock if there is any depth
movement it does the DRO is not detecting it so I amuse not movement over
.0005" and this is with a stock mill, I'm not done with the CNC conversion.

Painted Myself Into a Corner Again
Thought I was being clever this time and started turning a piece on a long hunk of 2" stock - so I'd have plenty of margin for error.? See photo: ?
Next step is to drill a hole through the center of the turned section, starting from the tailstock end.? Unfortunately, in my cleverness, I didn't account for the length of the chuck and the drill - I either need a longer lathe bed or a shorter set up.
So, the next step now is to cut off the turned section and re-mount it in my chuck.? Which leads to my question.
I've gotten pretty good at centering a piece in my 4-jaw chuck, using DI.? But, in this case, I need to center the counter sunk hole (where the tailstock is currently mounted) and also make sure the axis of the hole I drill will be parallel with the axis of the turned portion (IOW, make the axis of the turned portion parallel to the bed).? The turned down portion is about 2" long, so if it is not aligned parallel with the bed the hole will be off by quite a bit.? Any advice on the most efficient way to achieve this alignment?.

Disregard my comment, I was unaware that the 4700 has a
spindle that moves up and down, unlike the other mini mills where the entire
head moves up and down.
Mike from mikesworkshop has the correct
solution.

Hello Johannas,
?
I'm not familiar with the 4700 mill, but from the photo of it
on the LMS website, there is a column/gib locking lever on the left hand side of
the column. Locking this down should lock the head from moving. Any movement
from vibration of the fine adjust wheel while milling should not matter, and
will not move the milling head.
?
All unused table and head travel
should be locked down prior to milling.

This is the fine-adjuster to LMS 4700
Mill.
Have somebody made a lock for
this?
My adjuster is moving (turning) when I am
milling, and before I am doing something stupid, I want an advice from
you.
Best regards

Hi and thanks for response. Here is how the fine adjuster looks inside: https://www.dropbox.com/s/s2tx6cgt0j8wm7s/adjuster.jpg?dl=0 ? My thoughts was to look the axel from underneath, it have most of the steel to make a hole for a screw. But may maybe I can fix the problem from the other side as Mikes workshop suggest. http://mikesworkshop.weebly.com/mill-quill-lock-lever.html ? I will think about all suggestions for some days and I will come back when I have done the job. ? /johannes
