I like the new gear opening video to your episodes! Your content is great!

[@perpetualmotion1]

@@dgoode-ys3nx thank you, my wife is trying to clean up my act🙂

[@hasletjoe5984]

Wiggles cameo was great. Love the new format (Music overlay) you got going. Hats off the to the one responsible. Always something unique here. Thanks for the video....

[@perpetualmotion1]

That got an "awe" out of the wife, thank you for the kind words 🙂

[@ypaulbrown]

So great to see Mr Wiggles working on his project….you are a wonderful dad to be introducing him to machining and giving him his own lathe….best wishes, Paul

[@perpetualmotion1]

Just trying to pass on what my dad gave to me🙂 thank you.

[@joeappelget6792]

Excellent video! It really pays to be able to do everything in house. The broaching doesn't look fun. That material is a whole lot harder than the cast iron gear we put the key way in. The editing department has just the right amount of music while still letting us hear the machines work and have you explain what is happening.

[@RalfyCustoms]

Happy days Andrew buddy, great job there, well done mate, thanks for sharing 👍

[@perpetualmotion1]

Thank you, I was very sick of it before I got it finished, and after editing three hours of video my wife said the same thing 😂

[@RalfyCustoms]

​@@perpetualmotion1I'll bet 😂

Ouch at 12:10!! Interesting fix with that concrete drill bit. Hi, Wiggles, and nice paint job!! Great job, Andy and Alison! Love the music that plays during the time lapse portions. Have you thought of the following: What about asking your audience for a list of suggested music to play during future time lapse portions? Maybe a cool way to get your audience "interactively" involved, lol! Maybe someone already suggested this?

[@perpetualmotion1]

KZbin is really Nazi about copyright laws, the only music we can get away with playing is open source stuff unless you want to get really involved with paying licensing fees 😑

[@pvccphysics2793]

Ah, true that!!

[@eyuptony]

Fun and games. Interesting to watch you problem solve.

[@nitroracer-rollingthunderm9033]

Great video Andy ...

[@perpetualmotion1]

Thank you

[@ypaulbrown]

Cranking the work and videos out…Thanks, Paul

[@perpetualmotion1]

I'm just cranking out the work, the wife is cranking out the videos 😁

[@redmorphius]

“That would be a big heavy duty NO” …… lol I don’t know why but I laughed so hard. Never heard that one before

[@perpetualmotion1]

Now that you mention it neither have I😂 it just seemed to fit the moment.

[@ypaulbrown]

28:35 man than is scaredy, I have used the same press for broaching, but only key ways, the effort you are using would make me think that the broaching was ready to snap any moment….

[@perpetualmotion1]

It is without a doubt terrifying, I go to great lengths to ensure that everything is square and plumb, I'm sure misalignment would result in disaster.

[@warrenjones744]

I have bars with tool holes both ways offset and straight. to be honest with you if they are in a straight line it's no big deal. The early Climax bars were that way. When I bought mine way back in 1996 we used round tool holes and a 3/8 or 1/4" square broached tool sleeve you can buy from MSC. The fixture that climax sold to drill the bars left the holes in a line. I still use the original bars and have some drilled with holes every two inches for two or more feet of the bar and there is no problem with bar bending or warping or acting odd in any way. My 1 1/4" bars are all bored this way. In the past 15 years or so the 2 1/4" bars are mostly 1/2 square broached because 1/2 inch tools are longer and much more rigid. I bought the square broached bars them from Climax simply for connivence and add holes when needed. Now there are, dare I say better and less expensive sources if you cannot make your own. If you have two holes going at the same time and no central support with bars bored in a straight line, tool pressure can push them around a bit more and can bore the holes small or chatter some etc... Perhaps the offset holes help mitigate that I never investigated, if there is room I add a support.. I found that if I rough out multiple holes in one setting, I can finish them individually if need be. it pays to experiment if that crops up. My two cents worth anyway. Cheers

[@perpetualmotion1]

Wow, that's a lot of information, thank you for chiming in. My main objective with this is just to show people what does or doesn't work so they don't have to make the same mistakes I have 😂, I learned so much poking around on KZbin about 10 years ago that I feel obligated to return the favor. To your point about support, I think the best piece of advice we could give any new guy is always add more bearings if you can, and strictly never set up with more than 2 ft between bearings on a two bearing setup if humanly possible. I've definitely broken that rule in a pinch but expect to eat some tooling and take a lot of light cuts.

[@vettepicking]

They sell square tool bit sleeves that insert in a hole in the bar... even have a set screw for advancing the bit

[@perpetualmotion1]

The factory climax bars and the first couple I made had threaded holes with a set screw to advance the tool, I was thoroughly disappointed with the accuracy of those systems, and then I had one of those dang set screws back out while I was in the middle of boring a hole and get wedged between my bar and the bore😡 I have completely quit using those, I get much better results with my custom built dial indicator holder. I have looked at those tool sleeves, I'm not really excited by the fact that they require an even bigger hole than my broached half inch hole is, it seems to me like that would weaken the bar more than I care for.

[@JonesMetalCraft]

What is that little drill sharpener you used? I need one I think. I thought for sure broaching on the mill would work.

[@perpetualmotion1]

It is a SRD drill sharpener, I absolutely love that thing, it's the simplest one to operate I've ever used. I can assure you I was highly disappointed when that trick broaching on the mill didn't work, back to the old method 😑

[@TheJohndeere466]

I have a 10" x 12" x 8' long boring bar I use on the lathe once in a while boring out 36" diameter bronze bushings.

[@perpetualmotion1]

A touch larger than mine😉

[@silverbullet7434]

Use hydraulic jack from spindle to push key cutter thru..

[@perpetualmotion1]

I want to build something that hooks around the bar itself so that all the forces are contained without applying load to an external machine. I just haven't had time to sit down and really design and build it yet. I only end up needing a new bar every once in awhile, and in between then I always seem to have more pressing problems to address.

[@matthewmarquette]

???? Where did you get keyed crome rod. My crome rod suplloer could not get

[@perpetualmotion1]

I make it, it's just 1045 Chrome cylinder rod stock that we cut a keyway into. That's the same thing climax does.

[@warrenjones744]

In thirty years I have never found a steel supplier that offers chrome bar keyed. You have to machine it somehow

[@matthewmarquette]

Figured the crome would chew up cutters rather not chew up mine but if that's what got to do so be it

[@perpetualmotion1]

@matthewmarquette it's not actually that big of a deal, when I cut them myself I generally use a horizontal type cutter in an arbor, I'm still using the same one about three bars later..

[@warrenjones744]

@ there are two kinds of chromed rod. there is induction hardened chrome rod and that is not what you want. They also have chrome plated rod stock that is not hardened sometimes called soft chrome rod. this is what you want. the chrome machines off just fine and is not hard on good tools.
