Chicken lights mistakes

Does anyone have a trick for milling a 45 degree? Could I use a scrap piece of stock, drill and tap it, then bolt the workpiece to that at the 45? That would let me use the vise still, and keep the cutter away from the vise?

Not sure what you are after Dave. Got a photo?

V-blocks generally work great - either one on just one side or paired with one on both sides.

For a job that doesn't require a really perfect 45, you can just put your block in the v-grooves of your vise jaws if it has them.

Whatcha up to?

Trying to whittle that
 
This looks like something to collect/collect some chains and hoist by the loop.

Can you approximate the shape by replacing the 45 deg. cuts where the smaller section meets the larger part with drilled (or bored) rads and blend them by milling up to the tangent edges?

For the other 45 deg (outside) chamfers you could just grind a rad or machine by clamping the part in the vise by its thickness at 45 deg and mill the chamfers? I’m guessing you don’t need an exact 45.00 degree chamfer so simple angle measurement would be good enough rather than Vee blocks etc. Maybe that’s what you mean by bolting a piece to it and holding it the vise? I don’t know what size vise you have to know if just putting it in the vise is enough.

You could also clamp it face down but raised from the mill bed on 1-2-3 blocks or even some scrap material, that would do away with bolting it to something for fixtureing. You’d have to reference the plate at 45 deg. to a square edge and mill the corners.

Is that any help?

So you're saying you would re-mount the vice at a 45 (ish) angle to mount the part to mill the angles?

You're right, there's no 100% precision needed, it's mostly for looks/ trying to make a better tool. I have a four way chain collector that was basically torched out and welded up, but looks like junk. Works great, looks like hack work

Actually I meant to put the parts in the vise at a 45 deg. angle (vise mounted flat on the mill table) and end mill the flats. Thinking about it though, if the amount of the part hanging out of the vise is long then it might set up vibration from the mill cutter which might not be good all around.......

If the vise won't do it then you could do the other thing and mount them (face down) to the mill table using a hold down kit. Just put a spacer under your part so you can side mill (the overhanging) part at 45 deg. without hitting the table or the spacer with the end of the mill. I've come close to doing something like that but thankfully my table is still pristine somehow!:D

Hopefully my CAD (Completely Analog Drawing) below will make my words make sense!

I agree with @Tecnico. Might also be easy to just lop them off with a band saw or a cut off wheel.

Milling works better for those that who don't have a $50 Alberta band saw. I suppose I could use the acetylene saw......;)

The first version on the brass collar, I drilled a hole and used mechanics wire to attach the flag. That ended up ripping out. :rolleyes:
So I thought use a hose clamp, had the collar turned so there was a boss for the hose clamp. The hose clamp is too large for the grommet on the flag :rolleyes:

So zip tie and mechanics wire instead

One of the office lady's sons just put a flag pole on his truck. Yes, I'm that immature to see who's got the bigger flagpole :D
