Cross Slide

…smart arsed titles seem to be beyond me at the moment…as is remembering not to use bad language…

Before I started writing my own blog, I used to get annoyed when another blog writer wouldn’t post often enough. I wanted a “fix” every couple of days. But, some writers would go weeks or months between posts. I would think “what the hell are you doing all day? Do another entry!” Now I know why. We’re all busy! Time gets eaten up everywhere. It seems as though when one gets past 50, a Big Bad Time Eating Demon (Big Bad TED) appears and starts devouring all one’s hours voraciously.

Of course, because one hasn’t recorded things in a blog, doesn’t mean one hasn’t been doing important stuff. Mrs Linn and I have been on our Important Lathe Course and we’ve had Important Friends visiting.

So, time to accept Big Bad for what he is and get on. Blog when one can. Stop worrying. It’s not that important. Besides, who sets the time rules? I do. So rulemaker, change the rules! Yep, I’ll blog when I can. Is anyone there anyway?

It’s been a frantic – although thoroughly enjoyable – fortnight. Lathe Course in Axminster. Guitars on the Beach (with Ian Gillan no less!) in Lyme Regis. Trams in Devon. Chester. Segways in Delamere Forest. Manchester (actually, that was an effort to like. Can’t win them all). Great Friends with great food and Real Ale.

Back to the Lathe. Remember that? Big Bad got in the way of me finishing it before going on The Beginners Course (during which I learned a lot about Beginning and made A Thing). Since then, I’ve not touched it except to show it to Peter. But before that I got the Cross Slide completed and most of the Top Slide, or Compound Slide, as Bob The Course Tutor called it.

Cross Slide

This is a simple structure…

…and came apart easily…

The part with the numbers is the Micrometer Dial, and now I know what it’s for! It’s quite important, you know. Here’s some detail on it. A lot of muck on the reverse side…

…obscured a circlip fastener…

…which comes out easily with the right tool…

…and the part on the left pops out easily…

Note the “wavy spring”. After clean up…

…and reassembly…

The Dial is designed to move with friction around the dark metal insert, which is attached to the end of the Feedscrew. It allows you to set a starting point, zero, and then move the Cross Slide by a measured amount using the Dial gradations. Except I don’t yet know the magnitude of each Gradation, other than that there’s eighty of them. But eighty of what? More reading needed. Laters.

Cleaning the Feedscrew…

Using the Gib Strip with 2500g wrapped around it to clean and polish the dovetailed ways…

Reassembling the Ball Handle Assembly and the Micrometer Dial onto the Feedscrew end…

…and that assembly on to the Cross Slide body…

These little screws go into the holes next to them and tension the Gib Strip…

The points of the Gib Strip adjusting screws poking through the other side of a nice clean body and Gib Strip…

The Gib Strip is on its side here. The correct position is flipped up away from the viewer. Fitting the Feedscrew Nut back on to the Saddle…

This is the only connection with the Saddle. An expanded view from underneath…

…and from above…

I used oil during all the reassembly, particularly in the dovetailed ways and around the Gib Strip and Feedscrew. Lastly, adjusting all the Gib Strip screws to achieve a smooth action with no play…

The end of the Gib Strip…

Adjusting was straightforward. I started at each end and worked in to the middle, winding the Cross Slide backwards and forwards with each adjustment until it felt right.

Right, Top Slide next…
