|Thread: Boring table|
Yes I do have a vertical slide for this cross slide. I could have carried out this operation on my Stepperhead lathe but the Chipmaster is a much bigger and more rigid lathe and even on this I could only make about .020" cuts without chattering etc. I modified the original cross sliide by adding 0.500" steel strips bolted from underside.

I have added tee slots to my Chipmaster cross slide this enables many operations like this

|Thread: Getting old, selling lathe|
Hi David, I read your hard story with sadness, but your strength to keep pushing forward is uplifting and I hope you will get better and manage to start out on new projects yet to be covered. Its the mind that needs to be kept occupied most of all, with hopeful ideas and possible achievements. All the very best to you and look forward to your new ideas.

|Thread: Need a pen to draw the "finest possible" lines?|
I used to use plastic leads on drawing film. By rotating the pencil as you moved it, it was quite easy to draw a fine thin line. The other trick was to push the pencil so that the lead was in compression, not bending.

I think the elephant in the room in this discuussion is tidal power. We live in a country surrounded by sea and high tides, which rise and fall twice a day 24/7. Why do we ignore this?
|Thread: Questions on an MLA inspired toolpost|
The central post is a parallel 1/2" threaded column fitted into the topslide. The expandable dovetail block fits over the post and firmly down against the topslide top face, then the solid tapered plug is fitted into its matching tapered bore in the dovetail block and over the post. The plug is then pushed down by the locking lever screwing down on the central post. This has no effect on the preset height setting, it just expands the dovetail block to lock the whole assembly in position. The locking lever only needs a slight force to lock it all firmly in position.

I chose the expander plug to be made from cast iron so it did not stick in position. It has an included angle of 40 degrees. The block has through holes and grooves to make it flexible and the adjusting screw has a half section that fits into the groove in the block. All this to minmise overhang. More pics in my album

|Thread: The ettiquette of sharing designs|
A while ago I made my version of the MLA toolpost and this is the reply I got from the MLA membership. So as long as you credit the originators I do not see any problem with copyright.
compliments on your nice looking version of the MLA toolpost. Also, the topslide compound it's mounted on is sheer elegance.

|Thread: Why aren't carbide chop saws used?|
A long while ago I made a worm geared drive HSS cutting saw, but it just did not have the rigidity and power required. The blade cut but it chattered badly, so I discontinued my efforts. It was never going to work as I dreamed it would.

Thank you Dave for your good words and thoughts, and for all you did for MEW.
|Thread: Cross-slide fixture plate considerations|
Vertical slide added
I did not remake the whole cross slide, I just added 1/2" thick steel slabs with notches cut along their lengths to form tee slots. The slabs are dowelled and bolted from the underside to the cross slide. The space between the tee slots still enables access to the cross slide gib adjustment screws. The result is a slight loss of clearance over the cross slide but thats ok for me.
I have added tee slots to my Colchester Chipmaster lathe. You may not want to go this far but it has proved to be very useful for all sorts of machining operations. It did also involve making a new topslide which can be moved and locked anywhere on the cross slide.
|Thread: oh my goodness|
I did have a milling machine, a Dore Westbury, but a long while ago I made this Four jaw chuck from a steel billet a freind gave me when he gave me his home made barbells, so one end of the barbell became this.

Cillary Blue are a good company who make new lenses to your prescription and fit them to your old frame.
