What did you do Today 2024

[Nigel Graham 2Participant @nigelgraham2]

Not only complex mechanically. There was a heck of a lot of advanced maths in designing steam locomotives.

.

I’m presently overhauling a long-stored 7-1/4″ gauge loco, a freelanced, doubled version of LBSC’s Juliet design – but this evening finally carried out a minor repair on my Myford lathe!

The Workshop Gremlins had long since spirited away the knob from the end of the half-nuts lever. By chance I found a spare spherical knob on a short rod – from what I don’t know – so I modified that to suit.

That should make screw-cutting less painful. The bare end of the little lever is a bit sharp!

.

All I need do now is determine why it is frequently very difficult to engage the half-nuts, necessitating briskly bringing the handle up and waiting for the next number on the dial to amble round…..

Hi, I needed four more T- Nuts for my tilting table, so today I decided to make some from a piece of 12mm thick flat black bar. After cleaning off the mill scale, I trued up all the four edges, and set it up in my vice, on my mini mill, then reduced the thickness down to 11mm, 20mm in on each side. I then mill the two outer edges and two channels, to a depth of 5mm, to form the part of the nut, that fits into the slots of the tilting table surface.

When these were done, the piece of flat bar was long enough yo make six T-Nuts, and so I drilled and tapped six holes for 6mm threaded rod, and then hacksawed two slots in each side to produce my six nuts.

Tomorrow. I will now be able to cut the nuts off the rest of the bar, in my band-saw.

Regards Nick.
