The OP refers to attempting fitment " and without the scroll in place".

Not sure Ultrasonic Cleaning would be my first choice. Paraffin, stiff brush and lollipop stick would be first choice.

A tyypographical error!

Taf - Z Axis?

Dave if you have managed to download the complete Myford handbook I doubt much else exists. The Handbooks were usually well written but not quite "workshop manual" material. If you have a specific query someone on the forum will be able to help. 254's not endlessly disected in the same manner as the 7 series (an observation not a complaint).

Julius, I wouldn't get too excited, stylus and screw marked/rusty no guarantee it hasn't been round the block several times. Not necessarily ruinously expensive to purchase new.

Dave try Googling Myford 254 Handbook, www.lathes @ £48-00 but there are other sources.

Larry, not sure if you have discovered the lubrication point at the rear of the quill in the gearbox casting. On my mill you have to remove the guard, microswitch linkage and a blanking panel you will then find a hole through which to squirt oil.

Robert

Larry thank you for enhancing my reputation!! My view regarding the spare screws remains the same. Clearly they could not escape from the gearbox and therefore maybe left by an absent minded operator or fitter at Chester or the manufacturers.

Taf I have a link to a complete strip and rebuild of the head and hearbox, not that you will need it for this issue, but I printed it off for future reberence and you may care to do the same.

I fitted the DRO reader to the quill and this takes up little space and connects direstly to the three axis DRO screen. I used linear bearings to mount the reader and have some rough drawings which may be helpful. I can never manage to upload anything on to this site so if you send me a PM with your email address I can email them to you directly.

Taf I have a Super Lux and find it acceptable in most instances.

I fitted a Chester power feed which makes life easier and produces a better finish. Gibs, are the adjuster screw heads engaged in the slots correctly. Is there any crud under the table or dovetails? I have read somewhere that the Gibs can distort which can also cause the symptoms you describe, the cure was to machine the bow out of the strips.

The Gibs or crud may also produce the tramming error in spite of the weight of the table so perhaps investigate first which will hopefully leave the column undisturbed.

I found the backlash in X,Y and Z axis a bit irritating and whilst it is possible to adjust X and Y there is no provision for adjusting the Z Axes. I therefore fitted a Machine DRO covering all three axes, with the reader fitted to the quill. This has improved the functionality and accuracy of operation and as i tinker in metric and Imperial units a useful bonus. If you would like images of the Z axis installation send me a PM

Download the Grizzly manual far better than the Chester version.

? Surely the drive for the gearbox comes from the headstock which in backgear operates at a reduced speed otherwise the headstock rpm would make a nonsense of the gearbox output rpm??? for screwcutting???

RobertButler

Larry I have sent you a PM with my email address as it is as difficult to upload images as to post on the forumn. If you respond I can just upload the images and forward them to you directly.

My cover is securred by two cap head screws which engage in key-slots in the plastic cover to hold it in place. I wonder if the cap is non original and the screws either vibrated out or are a red-herring. I can't see how screws can have exited from the gearbox.

Are there any vacant threaded holes in the gearbox top cover around the spindle? Did you buy the machine new or used? If you would like an image of my machine and also of the Z axis DRO, send me a PM as I can't be bothered with uploading images on to the site.

Regards

Robert
