What Does A Machinest Do On His Day Off???

#1

Work some more!!!

OK Jettywolf, metal shop is in session.
This isn't boat related but it does involve ALLOY 3/16 6061 T-6 plate
Needed to make some wheel spacers to help cure a rubbing problem on my truck that I discovered the other day.

CNC vertical mill
Milling fixture which allows work piece to be held down with pinching type clamps

Locating roughly the center of the work piece. Band sawed the part +1/4"

High speed steel endmill tool bit 1/2" dia.

Drilling with the endmill to start the cut. Some, but not all endmills can feed down. Depends on how they are sharpened on the face.

First cut half way done. Staying .005" from finished size

Center removed. One more pass to take to finish size (ID)

Drill holes for lug studs before cutting OD

Cutting OD to size in one pass (size and finish not critical)

All cutting finished, ready to remove from mill

Deburring the OD with a 1" wide belt sander using the soft part of the belt (I like belt sanders) :P

Here's a handy tool for you alloy guys. Works great on inside edges as long as the burr is not too big

Finished wheel spacers. I wonder if they are going to fit :shock: :shock: :shock:

Took around 1 hr. 45 min. to do @ $80.00 per hour + materials
Maybe I should have looked at a JC Whitney Catalog :lol: :lol: :lol:

Scott, they sell those at Pep Boys for $8.99 ea.

#3

They do?
I bet mine are more parallel

How do the pictures fit on your screen?

#4

Scott , just messing with ya on the parts , they look great.

The pictures are just a little BIG but they are very clear.

If P-boys did have warped ones the wheel and lugnuts would make them parallel. :D

#5

Thanks Les,
I was experimenting with what size would be too big. Big is good, but too big is not good. That's what I was told at least

If the one's from pepboys were warped and parallel, that would be OK
But if they were flat but not parallel that would be no good... think about that

You're hired, you start Monday :D

Is that a Proto Trak bed mill?

DITTO...your hired to start making specialty milled parts for all of us AAB members at a 50% discount......but the best I can offer is Free charters. Cuz I have no $$, remember, I fish.

C'C'mon :roll:

Man, with the ideas I have floating in my head and if I had any kind of machinery in my vacant 2 truck garage, I'd be doing something...Oh and some skills too.

Scott too cool. The more I see your posts the more I like you. Do I have a project for you.... Super bright leds my build. Need housing for underwater squid lights.

Jettywolf now thats what I call a tinny........... no offense Scott... I have a pristine 19' valco Bayrunner in my garage.... I must be a Plinny.

Have a great day

AlloyTroy asked: "Is that a Proto Trak bed mill?
No it's not. The brand name escapes me at the moment, but just picture a Bridgeport mill that has a head that slides up and down instead of having to crank the table up and down. This one is fairly basic with an X, Y and Z axis, controlled with a computer head that you can program by hand using a simple menu and then can be saved on floppys for later use if desired

Even at a 50% discount it will still feel like that it shouldn't cost that much :lol:
I'm constantly thinking about things to make, modify or fix. It what keeps me wanting to keep working. For the amount of years I have in, I know it's not the pay or benefits (that's for sure) :(

Mark, Have you been getting together with Kman and coming up with some crazy bright LED's that need all that special circuitry and heat sinks so they don't burn up and catch fire? However, I do like their low amp draw though.
Maybe we can find an existing housing that can be modified to accept them?

Well heck, they fit. but...

They don't seat all the way because of...

A large radius on the hub

OK, now I'm at home without a lathe that I could have used to chamfer the corner edge back so it will lay properly.
So I used a basic tool that any ALLOY guy should have in his tool box.
A sharpened triangle file (1/4 or 5/16") that you can do some serious scraping on corner edges with

Keep it sharp by using a bench grinder (don't let it get blue while grinding, you will remove it's heat treat)
Hold it in the first bend of your three fingers and pinch with your index finger and thumb.

Work towards yourself with a very stiff grip and wrist (no weenie grips)
Hold the tool fairly flat and be careful that if you slip, you won't be cutting yourself

This tool can be used on many of your projects to break any sharp edge.
I hate sharp edges on a boat :evil: :evil: :evil:

I hope that I may have passed along some info that might help you work on your projects

In2deep (Scott) I have alot of electronic assembly equipment currently have a metal printed circuit board (pcb) (aluminum alloy of coarse) made. I have to use welding goggles to test these suface mount Leds. I prefer to use a metal housing. It is a heat dissapation thing. Circuits are isolated from the metal pcb. I want this to be a submersible light bar.

Heh heh

I have been teasing K-Man, maybe to coax him to check out this site. I think this site would enjoy his posts. I think he would enjoy this site, there is soooo much to to learn and see. Will send you a PM.

You going to the Halibut seminar at Pacific Edge on the 8th it's fun to meet people.
How about the Custom Rod Show on the 3rd. Jettywolf woud be the proverbial kid in the candy store.... I think Deep Color is there.

It's hard wanting to be on the water and waiting to have my annual spring servicing. Found some wiring that some rodent wanted to chew. Grrrrrrr.

Take care.

Hey Mark,
I forgot that Kman has an alloy!
How does it go?

I was experimenting with what size would be too big. Big is good, but too big is not good.

The standard size that works well for sending in Email's and posting on forum pages is 640X480.

This keeps from blowing the screen out on a lot of peoples computers + for poor old Welder aka Les still being on a dial-up, they will load faster.

Go back to your PhotoBucket account. Click on the pix. Then click on Resize.

Select- the one that says 640 X 480 size.

A Birdgeport CNC mill is my brothers favorite tool. :)

But it's high speed Dial-up :lol:

#15

Great pics - I love that stuff...

JC Whitney! I remember buying a 2 into 1 pipe for my rad 1974 Honda CB350. Though I was going to give Kenny Roberts a run for his money.....

#16

Kenny Roberts, I like that name , KING of ROAD RACING for Yamaha

3cyl. 500cc 2 stroke WFO = Wild ride :shock:

Jay, my last name is Roberts and I rode Yamaha's till I was killed then I went back to dirt bikes [ Trees and rocks don't move ]
