POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

[ChazzC]

I lived in New England and New York State (A LOT of deer) for many years, and a lot of folks I knew had those deer whistles.
I also knew a lot of folks that hit deer, and a lot of them had the whistles - A mixed bag, at best
I've had deer run into the SIDE of my vehicles a couple times - I mean the deer were running flat out, full tilt, probably being chased by something, and would have paid no attention to any whistles, I think.
The BEST defense against hitting deer (as well as dogs and chickens), IMHO, is good headlights, and powerful fog / driving lights, that light up the sides of the road, as far back into the edge of the woods / fields as possible - You seeing them, and them seeing the lights early on gives you the best chance of stopping them, before they make a fatal choice.
But that's just my opinion, and YMMV.

The “warns” or whistles only work at speeds above 35 mph, so slower moving vehicles could fall victim. At slower speeds, legally pointing headlights & fog lights are helpful. I can report that I have seen deer (and other critters) preparing to cross in front of me turn away. Also, wife & daughter’s driving habits haven’t changed in the last 20 years, but there haven’t been any further collisions.

I'm much more a "whittler" than I am a machinist, so when I hit the target dia. on this backplate, I was pretty happy. I was concerned about the surface finish, and had .400 to start with and adjust/ w/ chuck diam, then I looked at the one I had been using, got both with my lathe purchase, and I was ok. Tuff stuff tho, now I have to drill the holes, not near as intimidated as I was.

It looks great.

Thanks, I tried EVERYTHING

Well, you found the right combination! Nice finish.

Wait, is that wobble broach eccentric only, without any type of angular deflection? I didn't know that was even possible. Rotary broaches that pivot on a ball cut with the corners of the cutter, but on an eccentric the cutting action is completely different. How does it work, with the tip being rigidly fixed to the axis like that? Does it just rub around the work and wallow like a form tool, since it can't do any cutting just orbiting around like that!

There is a 1* angle built in to the body of the broach.

The shank is a separate piece from the body. A 1* cut is made on the back of the body prior to assembly, and the parts are assembled offset such that the tip of the broach runs true (no eccentricity), but does "wobble".

After it was assembled and tested, the outer diameter was turned down to also run true. The front face does still wobble in use though. This approach does require the broaches to all be the same length to a pretty close tolerance, as there is only one point where the tip runs true, without any eccentricity.

That's probably clear as mud....

Thank you, that makes sense. Do you have better pics of the internals?

Last few days i've been dealing with the main dealer for VW in macedonia with this E-golf. After lots of excuses i got the main menager he come opend the boot press i and said is moves golf is a sport car the have to be stiff. So i grab his suit and told him get in the car, i pretty much trow him inside. First few feet the parking lot is smooth he started talking but when we got on the street he actually bite his tongue from the hardness. That shut him up i pretty much hit all bumps i could find, when we go back he has blood dripping from his mouth and told the other manager to make a work order for replacement of all 4 shock absorbers and spring. One of the mechanics come and ask me how hard did you punch him. I did told him he was close to getting punched out but i did not do that to him. I left it to get fixed, i did take couple of pictures you can see that is a paved road and the outside is clear but even a camera can't focus from that hard ride.

Well, my Chinese 4 jaw and backplate just came in. Looks like I'll be turning backplates this weekend. It wasn't supposed to be here till Monday. But I learn the best if I can do a repetition in short order, so kinda glad, but dang it's tedious.

I have a 2 hour plumbing job lined up for today . See you in 3 weeks !
