Tiffany glass clock.
Attractive little project which uses up lots of off-cuts of glass!
Step 1: Cutting the Glass
If you are a frequent follower of instructables you may recognize these bits of glass? A while ago i did a instructable on HOW TO CUT GLASS, and at the time decided to cut these sections of glass to make an interesting background. I decided to cut the sections with 30 degs angles so i could make a clock, and i have finally got around to making it!
So if you need loads of information on cutting glass please take a look at my other instructables. I will only cover the use of the template in this instructable.
So to make a clock you need to cut the sections of glass with an angle of 30 Degs. You can see in the pictures and on the video that i used a 60/30 set square to cut the triangles first, then used my template to cut the radius.
Same as before i use the yellow fabric to stop the glass slipping around then holding both the glass and the square firmly against the piece of wood i scored the glass using one firm pass with the cutter.
For the radius i used the template pushed against the piece of wood.
Once i had cut all the sections of glass i cleaned up the edges on my grinder and trimmed the end to make the center hole. Then checked that all sections fitted together.
Step 2: Putting It Together.
I tried a few times to fit the glass together but each time i ended up with a step. so i decided to draw the correct size circle on a piece of plywood and position the sections inside the line. This helped to make the clock perfectly round and also showed where the center was.
Once the bits were nicely positioned i used sellotape to hold them in place.
Step 3: Soldering Together
This is the quick and easy section of the build. Once the bits are held together with the tape it only take a short time to run the solder over the joints. You can see i have used a penny washer for the center and this was soldered on first before i did the other joints. Due to the size of the washer it took a bit of time to get the heat in.
I like to solder on the back first then solder the front. this prevents the solder falling through if you do the front first. (obviously use flux on the copper)
Step 4: Finishing Touches
When you have finished all the soldering its best to give the clock a good wash to remove the flux residue.
Then i came to the question of how to mount/hold this clock? Some clock movements have a hook which allows you to fix it onto a picture hook, however this clock is quite heavy so i decided to solder a couple of rings to the back joints. The rings were made using 1mm diameter wire which was stripped from domestic wiring. This was bent into a ring then solder into place.
Lastly the clock movement was fitted. When i ordered the clock movement i made sure i ordered the correct spindle length. The website i ordered the movement from had 6 different length and 8 different hand designs/length. Mine was a Medium Spindle which is 16.5mm long and suits a clock face up to 6.5mm in thickness.
I hope you have enjoyed this instructable.
