Dear Neil/Jason is it possible to correct the orientation of my images for this posting please. Robert Butler

Dear Brian thank you, the link doesn't open, but I will try your other suggestion. Thank you Robert Butler

Dear Bazyle just a machine dust cover to cover the machine rather than a guard made of some sort of clear plastic fabric. Thank you for your reply. Robert Butler

Images at whatever orientation the system permits!!!

The website rotates the photos randomly even though they are all in one orientation from my pictures folder.

I have finally! (just) completed making the the parts and installed the magnetic DRO to the Z axis of my Chester Super Lux milling machine. Why is it the warranty always expires long before the components come into use. The installation comprises two alloy mounting brackets carrying two 8 mm linear bearings with an 8 mm shaft to which the the encoder is fitted using a machined alloy adaptor. The magnetic scale carrier is mounted between the two mounting brackets with provision for adjustment. An alloy carrier is fixed to the quill shoe via a 90 deg.folded steel bracket all works well and now I only need to look at one console when setting up.

The advantage of this design is the lack of slop in the encoder travel and no overhanging structures introducing inaccuracies in the z axis reading. The quill return spring acts sharply.

I am indebted to various forum members for inspiration along the way.

I will attempt to make a separate posting with the relevant images.

I have just completed the machining and fitment of a magnetic DRO to the z axis quill on my Chester Lux milling machine and would like to replace the old cover which is too heavy. Can anyone suggest a firm that could make one in a plastic material similar to the Myford lathe covers please.

Thank you in anticipation Robert Butler

Perhaps the packing was an issue and the speed range for a Super 7 and an ML 7 is NOT the same!!!! Robert Butler

No don't do that, wait for better and more knowledgeable advice, if it fitted before without issue it can be reassembled without any tinkering. Robert Butler

And? the question was?

Buy some new belts Robert Butler

I was looking through my back issues and noticed congratulations are due to our esteemed Editor - six years give or take! Thank you Neil. Robert Butler

We should remember them! Robert Butler

Presumably sales will be able to sell parts if they are still available? Robert Butler

Try Moore & Wright. Robert Butler

Is everyone on strike! No postings for ages. I am working from home but over the last couple of weekends I have managed to make some real progress with the components for fitting the Z axis encoder and head to the Quill on my Chester Lux milling machine. This will enable connection to the third axis on the Machine DRO console. I will then be able to dispense with the scale and remote readout. The components will fit to the front of the head and utilise linear bearings to guide the rail to which the encoder head is fitted. The project commenced in 2017 - how is it the warranty on everything I buy has long expired before its fitted or I use it?

I have used the slide hammer bearing puller which has several attachments suitable for extracting bearings and the debris left from failed bearings in blind housings on a number of occasions. Robert Butler
