Tom,
Did the finished part come out the way you wanted?
davidApril 20, 2014 at 9:34 am #57335David/Bob:
The part came out great! I had a little trouble dialing it in but with david’s advise and some patience I finally got center. Based on Bob’s suggestion I was able to clamp the sphere on the flats of the existing hole – shiming up under the shaft. This enabled me to pull my parallels back out of the way. Just to be safe, I placed another piece of key stock between my vise and the drill bit. I don’t have much luck with the manual stop and I usually forget to set the thing before I get things set up anyway.
So… here are some pics of my “work…”. It’s the poor man’s timing machine that I’ve been playing with.
I think I need to put a little divot in the BigBen crystal that I’m using – probably need a small diamond drill.
Thanks everyone!
TomApril 20, 2014 at 10:01 am #57336Now that is Cool Tom!
Beautiful tool you made there. Looks better than anything you could buy off the material house shelf!
Can you tell us what that part you machined was originally?
Thanks for posting those pics,
And Happy Easter,

Thanks for the complement. However, its probably not deserved. This is a cheapy loupe holder that I got from eBay. All I did was to rig it so that the holding part would allow me to hold a pair of tweezers. I got the idea from one of the watch repair books that I have. Here’s the link where I found the part…

Again… thanks for all of the advise.
Later,
TomP.s. Happy Easter everyone.

That looks great. If you decide to get the MUMFORD OPTICAL TIMER at a later date your fixture should work with it. If you decide to make a microscope stand in the future, use the same concept. It will be larger but the idea will be the same. By the way, how do you like your angle lock vice? It sure makes it nice for that kind of work. I am sure that your mill also performed beautifully. With good equipment, knowledge, and some effort, good things can be accomplished.
Great work,

That mill was a really good investment. It will certainly do more than I could ever ask from it.
Thanks!
TomApril 22, 2014 at 9:49 pm #57340Nice modification to create a new tool. In my book,there is really nothing that compares to using a tool that you have made for yourself.
I have a suggestion for alternate construction that will allow someone without a mill to make this tool as well. With a hack saw, cut the narrow diameter section of the clamp piece in or near the middle. Make a small sleeve or collar with a set screw near each end of the sleeve. Reassemble turning the slotted end of the original piece 90 degrees and tighten the set screws. If this is a “common” diameter, it may be possible to purchase the sleeve.

That’s a good solution.
Thanks!
