The final stages of my first machine project!!! *pics* *pics* *pics*

Woo after a few weeks of attending class and using a Colchester 13" lathe with a bridgeport something milling machine ive nearly completed the clamp!!.


On friday I took off the relieve cut areas, faced off the final cut to beautify it and then I knurled the screw. Its pretty much all done now, i just want to go the extra mile so tommorow I am polishing this thing till I can use it as a mirror! Im very happy with this thing, i pounded my initials into it because I can . I think theres still a little dykem left on the knurled area but i will take it off when i get to it. Overall im very happy. aaaaand the best part, after th is I get to make the same thing using the mighty CNC

Good work, except the part in the middle of the "C" where you got too excited on the mill. I give it a B+/A-. I am working on machining a power steering servo. So far, I have lathed the valve and milled and reamed the body, and drilled and tapped the holes for the end caps, and fabricated the end caps. The valve and valve body had to be precision work, and I turned the valve down to within a tenth (.0001") of .500, and the reamer reamed to dead on .500. The fit is so solid, I was able to suck water up by pulling the valve through the body.

Yea i know. Well the teacher claims its a flaw. I told him its a purposeful mistake because before i pounded my initials in there it looekd very much like everybody elses so i needed a way to distinguish. So its a sig, not a flaw

I meant the part where you went too far with the cutter. This would be coming down the vertical plane, into the horizontal plane, relative to the way you have it set up in the picture.

Edit: Damn they have me programmed here.

I made a few mistakes with the mill that day. Was not paying attention to the DRO, but i dont think i need accuracy down to .001" for a C clamp. I cant wait to polish this thing though

They look good polished. I have a few tools that I made, C-clamp included, that I polished using a polishing compound about 4 years ago, and they are still nice and shiney. Anything else that you've made(This is going to be my career, I will be a shop teacher, and this is my passion in life, aside from riding)?

nope i have not made anything else. I will be soon though. Well sort of,
im only in intro to engineering now. We do autocad work, the main machines (lathe and mill). And a little CNC work using mastercam, a spectralite 0200 from intelitek. and a monster bridgeport CNC.
But i have signed up for CAD I and II, thats a 2 year program after this. 2 hours a day. I cant wait, they just got a CNC lathe in there. Its
http://www.tecedu.com/products/equipment/lathe.shtml
I saw a kid make a chess set with it, very nice.

Im hoping to make my own cycling component of some sort, maybe I will eventually see if i can make a front hub shell.
Aside from riding and wheel building, this is probably one of my main interests which is good to know since ive tried countless things i think i have finally settled

I am going to start to work on a single-speed tensioner hopefully tomorrow.

No, man, a chain tensioner for single-speeds with vertical dropouts

When I get better light in here, I'll take a pic of the pneumatic engine I made a few years back.

First off, nice start Phantomcow2. How many times have you wished you were milling a bike part?

You need some to help testing it? hahaha. You need to post pix when you get that tensioner done.

I wish that a lot. Im not good enough with it right now, next year I can start making smaller things. My ultimate goal is a front hub. Im thinking with the lathe this may be possible. But that probably wont happen until next year or the year after.

Best wishes with that. I would make sure to order a lot of stock, you'll need all you can get. Use a 4-jaw chuck, too, those three jaw chucks give too much re-chucking error. The part needs to be dead on, or the bike will be not fun.

I don't know if i'd ever trust something I made myself. Probably would change if I had absolutely any shop experience at all.

Way to go RHHS all academic school.
