You made a typo:

It produces sharper photons than the other method :)

There's no such thing as a "Lazer".... it's "LASER" aka "Light Amplification by the Stimulated Emission of Radiation".... although these days, "Laser" or "laser" are equally accepted - i.e. the acronym has become just another word.

.....A small plastic O ring protects the glass from overtightening the nut.......

Actually, if the glass is as thick as Chris says, I think its the M3 that are more likely to fail than the glass

.......The glass is just simple picture frame float glass rim of only 1.5" thickness........

and I was just commenting on the inch-and-a-half thick glass ......   ::)

Picked the glass up this evening and very chuffed, they had done all three pieces! Looks amazing in person...pictures do it zero justice. Looks plastic on the photos but is clearly glass and has a green edge in the light! I couldn`t be more pleased.





Perhaps a little over the top, but I made a little video as sometimes the video function on this cheap camera gives a more life like shot that the still photos...gives you an idea!



Need to find a dial painter now!

What about that liquid glass etch acid they use to put registration details on car windscreens? That gives a frosted finish. You could get some stencils cut and use that perhaps?
Design your clock face and use the laser to cut a stencil from it, then either the acid or the more traditional sand blasting (just make sure it's well stuck down) would do the trick.

Cheers guys.

I`ve got a bit further with it today in terms of planning ahead to finish the dial. I`m rubbish at art and there would be no chance in me painting or making the markings on the dial. About 3 years ago I had a fascination with old vintage fountain pens and was blown away by the work of a Scottish calligrapher. Being in the middle of my summer holidays and having no work to do, at no charge (just cost) I offered to put him together a website, infact, he is now selling a few books and DVDs on it. Anyway..... who better to do some lettering and numbering on my dial than calligrapher - all hand drawn!!! .... it would be nice to think that is karma or at least helpful hands go around in circles  :med:

I made a massive step this evening. The daisy wheel has been a source of problems for weeks. Infact, the truth is my first attempt was simply to prove that the principle worked but I`ve added a bearing, changed some dimensions to fit my clock and it has never really be right, often skipping hours or jamming up.

So I went about planning cutting a new wheel. I`ve been buying lots of sheet brass for my project and it is causing a dent in my wallet. With my new found "parting" skills - I stumbled across a 2 3/4" brass bar at the scrap yard, 5" long. Even with enough to hold in the chuck jaws and the waste removed with parting. It is going to be much cheaper parting off brass blanks from this rather than cutting disks from sheet brass. Anyway, I cut myself a blank and then decided the ID must be 34mm to allow the pin wheel to go to full depth in the wheel and the outside diameter 40mm to give enough wall to each "V" to allow the pin to bounce/drive properly.

I`ve cut the other two attempts using a form tool in a fly cutter as I would when trying to cut a gear but this wheel is really thick at 2.5mm!! and there is just too much vibration and material. The plans say to cut by hand anyway so I decided to mark out and cut the notches. I had to work out my angles and then used my CNC divider to mark the points, joining them up with a ruler:



I cut each one by hand:


I then checked all the markings and filed to size which took a good few hours. The pin wheel was binding and I thought all was lost but then realised that the 75deg angle I had used, hadn`t taken into account the radius on the "full" daisy wheel plans - I`m cutting my daisy petals short on purpose as they serve no use other than providing an opportunity for the pins to bind!

So I rounded the corners. It looks more like a daisy now but the plans call for accurate radius on each petal as though the pin is following the tips of the petals. I`ve just rounded mine up to look nice, the important bit is the 75deg notch along with the slight radius of the edge leading into the notch.



I then speeded up the process of checking the daisy motion by putting it into the lathe and it seemed to work just fine! I`ve installed it on the clock and it has been running for 3 hours with no problem, which is longer than my previous two attempts! I`ve got a half decent feeling about this one... :ddb:




Just the master weight now....although a clockmaker who has given me a lot of advice doesn`t like my jockey weight and pulley so it looks like I`ll have to remake it! The I`m on to working with the brown woody stuff!!  :dremel:

Cheers Saw. Things are looking promising as it has been running just shy of 12 hours yet with no issue! I`m off to work now but fingers crossed for the rest of the day!

Just a few questions about finishing, in relation to this...

1. How would you "finish" the brass so that it doesn`t tarnish, like the big brass backplate and the wheels and pillars. Is it just case of rubbing them down to a polish with brasso ? I`m just thinking when the clock is running, I won`t really be able to easily strip the clock down to clean in!! Or do I just leave it?

2. My mistake, I didn`t really polish the pin wheel before assembling it, too eager as usual!! Is there any way of cleaning this pinwheel to a good polish or have I had it and it is a case of a making a new shiney one, then assembling?

Chris

Edit, just another quick one. Something as big as the backplate, how would you go about getting a high polish on it? Cloth, brasso and elbow greace?
