Precision Matthews Micrometer Stop for G4003G

[Splat]

Anyone using a Precision Matthews micrometer stop (meant for their PM1236, 1340, and 1440 lathes) on a G4003G? Was wondering if it'll fit. I have an email out to PM to see if they'd happen to know. Thanks.

Wondering if it will fit what?

The title says G4003G, and the first sentence.

Well gents, I got word back from PM that their micrometer stop will not fit the G4003G. OK. My shop made one broke. Guess I clamped it down too much and the 6061 split. Time to make another one.

Off topic, to the OP. I appreciate your signature... Amen and God Bless!

You might try to make it out of 7075 if using aluminum. Different designs, see attached document for the design that I have used and seems to work well. I adjust the dimensions based on the way that it sits on.

I always used a DI with magnetic base and set the carriage advance to 0-on-the-dial.

If anything goes wrong, the DI just gets pushed by the carriage.

That's a beautiful stop there, Mark, and thank you for the plans. Funny you mention 7075 as I found a nice piece today I will use.

Mitch, I've used my Noga holder to set the indicator. But then my OCD kicks in and I spend more time ensuring it's parallel to the ways, the moon isn't full, and the neighbor's kid's not working on his car with the loud as heck muffler.

@jbaccell Thank you. Amen and may God bless you, also.

When you are only looking for 0 the plunger does not HAVE to be parallel.
It only HAS to be parallel when you are using the thing as a measurement device.
As a Nulling device parallel-ness s unnecessary (good but unnecessary).
So I use the lines on the ways of the lathe to visually get it parallel and then don't worry about it any longer.
