Going to grab some stamps to put some numbers in the dial too. They come in various sizes so thinking of getting something small like 4mm.
Anyone have some advice?
Seems a good size:

Number and letter stamping, a quick and easy way of turning a mickey mouse, professional looking piece of work into something that looks like it was made at kinder!
I always struggle to line up numbers/letters so they look great. Then I live with regret for even trying!
Good luck.
Edit: 4mm sounds like a good all round size.

There are stamping jigs you can make, where you slide the stamp into a guide before hitting with a hammer.
For a single stamp, it would be relatively easy to make. I have seen people do this while still mounted on the dividing head so that the numbers consistently line with with the graduation lines.

I think I’ll make a jig. Try and do it right first time otherwise it will bother me if they’re not all straight and aligned.

Hi Neevo, Guys,
This is a jig that I made to do a similar job.

I used spacers behind the dial to get the correct distance. However I have a set of Pryor" 1/16" stamps that I used which are flat and used the rod to tap the end of the stamp.

However I then bought a set of stamps on 1/4" square shafts, so modified the jig to handle those !Best Regards:

Hi Guys,
I should have added the drawing that I did for the graduating jig.

Neevo, if you buy some cheap stamps, check them carefully ! As I found that the Chinese ones I bought not all the characters are accurately aligned on the body. Some of mine are slightly twisted or offset to one side.
The Pryor ones are much more expensive but are spot on and I found that Pryor will replace an individual stamp if it gets damaged.Best Regards:

Wrt what Baron said, I have seen a video of someone who made a jig to take several letters/numbers and they had to individually grind some of the stamps so that their letters/numbers were all at the same level when placed in the jig.

Noted. I did by some cheap ones but I’ll do a test run first to see if I need to adjust the jig.

Hi Neevo, Guys,
A shortage of HGV delivery and tanker drivers is being blamed !
Here in the UK we now have people panic buying fuel , garages are running out of fuel Locally garages have stuck ten pence or more on the price of a litre including LPG. A five litre jug of motor oil has gone up by a pound or more. Bus companies have raised fare prices.Best Regards:

Clough42 Electronic Leadscrew Implementation
Few more bits done on the lathe stop today. First up I finished off milling the top. I wanted to match the milled finish of the front/top and also leave a raised part for the indicator mark. Went well but it’s in oil at the moment after blueing, so will be hard to see. You can just see it in the pic below. I’m planning on filling it with some white paint after.
I also bought a carbide chamfer bit and ran around all the top edges so that will look nice too.
I also wasn’t happy with the gradations on the dial, so I did my best to set it up in the rotary table again and add another 0.350mm of depth. I also reground the cutter with a sharper angle on it and some positive rake. Cut really nicely.
Finished:
It’s much clearer and I’m glad I did it, although very nervous not to balls it up.

The clamp is essentially done but I need the ELS finished and setup correctly so I can cut the 1.0mm thread for the stop rod. But the clamp itself is together, working and looking good:
I still need to stamp the numbers plus I really would like a way to fill the marks. I tried crayon and it didn’t work at all. But for now I might live with it.
One thing I can’t live with is my bolts. The heads are a touch too small for my Hercus square wrench, so I want to make them again.
The problem I have is I can never get even sides when using a collet block, square or hexagonal. Here you can see one side of the square is longer than the other.
I always get this problem. Can anyone help me as to why?
I’m using ER collet blocks and milling across on the Y axis. I’m taking light cuts as I thought maybe it could be the cutter pulling slightly down in the collet in the mill, but I have both the collet chuck and Z axis done up tight.
