Well it didnt really matter because when the dust had cleared the thing went for over 8 grand. Two smaller watch jig borers where on ebay too. both at over 4 grand, not including thousands of do...

good project for beginners.

How long have i fought to keep my taps straight while tapping in the lathe or drill press. The chuck will always slip, and then you end up needing three hands. Today i decided to finally make the proper tap followers to make the job easy. For the lathe i started up with an old clapped out #2 Morse t...

Re: Really poor mans Cylindrical Square Need help

i do not believe you are making a slit small enough to filter out all but one color of light. I believe you are instead witnessing single slit interference of light. I do not believe i understand it very well but i am sure you can look it up on the web. And I have got to be on the search for two big...

Re: Using thread forming taps

i just got some 2-56 and 4-40 thread forming taps. I had never tried them but they worked like a dream. I wish i had know about them when i was working for a living. Regular taps always leave garbage in the hole, so you had to tap it. take it out, clean the tap, tap it again, and then hope when you ...

Re: Repairing 55mm ID thread on my lathe spindle

I know i am late on this one but i have a possible solution. I have done it before on 4" by 20 threads id. Take a standard tap say a 10mm 1.5 pitch. Any tap so long as the pitch is right. Grind the teeth off all but the one side of the tap. Then clamp that tap in a handle. )I turned a wooden handle ...

Re: Please check my price quote

I do not think that your customer would be happy with door handles made out of aluminum. Unless you can have them anodized or plated. bare aluminum is going to leave grey smudges on your hands and with time get dingy looking from contact with hands sweat and dirt

Re: Appropriate tool quality and price.

just to throw more fuel on the fire do not forget ball gauges. For me anyway i find that telescoping gauges do not work as well bellow 1/2 inch. Then i use ball gauges. I also like my inside mic (Mitutoyo 1" to 2"). It doesn't reach down in things but it is much quicker to get small readings, as it ...

Re: Mysterious Oil from Heated Bolts

oil leaking out of the bolts? that can't be good. I would not attache any important robot parts on with those bolts. Stainless bolts usually cost more and are far weaker than a grade 8 bolt. Wouldnt want to loose your robotic weapons packages, do to a bad bolt.

Ebay Micrometer

I should have know when the price was sooooo low and no one else was bidding. I bought a Brown and Sharpe Digit-Mike 25-50 mm for just 20 bucks. It looked like new and came in a wooden box, only problem was it didn't work, missing pieces. After two attempts and about an hour the new tiny parts are m...
