I have been running TouchDRO for at least the past 5 years. It is really fantastic and easy to use. I have a Clausing 8520 mill.?

I made my X and Y axis?DROs from some harbor freight?calipers. My Z axis is a 1-inch travel dial indicator that adjusts vertically. Photos are available?if you request. I also have some drawings. Regards,
Is anyone using Touchdro on a mill?
I have a PM-25MV and starting to look at dro's.

Re: Rotary table with dividing plates
Hi Dean This is what I want to my next Christmas, What shall I do? Start saving and get one from China ? Start converting all numbers into metric (or maybe not?) ?and later have lot of fun?

Re: Extending cross slide travel -- what is the currently accepted best method?
Ryan, I think that the normal size of the brass nut would not provide sufficient space to allow an insert. If you could fit a 3/4" block in the cross slide channel then maybe it could work and using the mounting screws to prevent insert rotation is a good idea.
The advantage of moving the nut to the end of the cross slide is that it enable a split delrin nut so if eventually some backlash occurs then it can be adjusted and the back lash eliminated. I have had the delrin nut in place for several years and I have never had to adjust out the backlash!!
I think it should be possible to attach a small shelf to the back of the standard OEM crosslide and then fit the split delrin nut to it.

Re: Extending cross slide travel -- what is the currently accepted best method?
A couple of years back I bought some
longer cross slide screws off of eBay. I am not sure if they were
custom made or actual parts from other lathes.? I made a couple of
educated guesses on the Grizzly web site and bought 3-4 screws for
other models of similar overall appearance, but none were a match
in any respect --- Fatter shaft, different pitch, different thread
form, etc.
Does anyone have any ideas if these
screws are custom made or repurposed OEM parts from a different
model(s)?

I need to machine some wider material.
Googling I can find lots of approaches and I'm struggling with
what is considered the best approach in 2022 (ideas tend to
evolve).
Gordon Scotts:?
Gadget Builfers:???(extends
on above but incorporates a handle extension)
Twinsquirrel:??(handle
extension is frowned upon and there is mention of buying and
cutting down a longer screw from LMS).
Mikesworkshop:??(referenced
in the above madmodder,? made his own longer screw but at end
mentions not lengthening slot in carriage [hindsight]).
Maybe if I take everything apart and pour over the above 4
threads in more detail the subtleties of the differences would
become apparent,? but instead I thought I'd ask :-)

Hi
What are you thinking
about??
for me is a rotary table
2 main thing:
Home made of wood and
this fancy heavy ?ones ?with a crank.? (on my next charismas
whish list)
I can write a book about
the wood ones and add 100 of pictures (ok, don¡¯t believe my
numbers) but I have used my home made dividing plates for a
generation. (First for making clock wheels.)
But today I use a wood
disk on the end of my lathe to drill holes into something I
put into my chuck.

More info, send a

Re: Extending cross slide travel -- what is the currently accepted best method?
That's pretty slick Mike!??I thought about doing an insert for the nut because like you say, I don't think threading straight into the plastic would hold. My thought was to do an insert piece that would have a nice course outside thread, screwed into a block of steel or brass. The metal block would of course be the main holding but with the holes drilled all the way through the screws would serve to keep the insert from unscrewing from the block or a few other screws could be used expressly to keep the insert in place. I'd have to measure sometime but I think a 3/4" or so block would fit under the slide. I think that would be sufficient size to hold an insert?
Thoughts?

Re: Rotary table with dividing plates
I use a small shop built dividing attachment to fit my mini-lathe. The headstock is worm gear driven. This unit fits right onto the minilathe and can divide just about any number of divisions. ?You could make your own easily following Ted Hansens plans from Home Shop Machinist.

Re: Extending cross slide travel -- what is the currently accepted best method?
> For my needs, the LMS kit lacked extended travel away from the operator.
The LMS kit has alonger screw (which should preserve the same position as stock away from the operstor) while the longer slot brings the position closer.? I thought this was as good as it got?

Re: Extending cross slide travel -- what is the currently accepted best method?
I'm sure you'll see why moving the nut back or extending the slot forward accomplishes the same thing as soon as you can physically see what is happening. Either one gives more room for the nut to travel towards the operator before it hits something. Hard to explain but much more obvious visually. You'll definitely have that Ah-ha! moment! :-)

I have a fixture in a quick change tool holder that holds three small parts that get a 1.3mm slot milled it them. I put the end mill in the chuck and feed the parts past it to cut a screwdriver slot. Not optimal but when lacking a mill it works fairly well. And beats the way I was doing it, cutting a slot with a Dremel tool and filing each one by hand.?

I have a mill, several.
Curious what was lacking in the LMS kit? it seems to achieve both more travel and relocating the travel. The same as "the Mike route". Obviously it's $$$ and not DIY
> What Mike means by "If I were doing this modification again then I would not mill out the carriage slot. Instead I would simply move the leadscrew nut 25 mm further back on the cross slide.

I understood the wording of what he wrote wrt accomplishing the same (and what you say isn't - no offense intended - any clearer) but I'm just not grokking it :-)? I suspect it won't make any sense until I take everything apart and re-read at which time I'll have an "ah ha!" moment.
I do like the idea of making a new screw from the perspective of also making a custom mated feed nut.? ? ? I'm assuming it would alleviate the need to do this:?
Thanks for the reply.
