Work Order - It's easy I swear.

[65535]

I keep flopping ideas around for my little lathe. Current idea requires a larger bore than the pulley I have has.

I may need a aluminum pulley bored from 3/8 to 5/8 and a portion cut off to shorten it.

It's a 6 step for my Taig.

Removing the smallest pully groove only and facing it there.

I can deal with any thread chasing on the setscrew.

Before and after cross sections.

Please add information to the title with information on what the thread is about.

I can do that for you. Might even have a Reamer that size. Let me know.

Re: It's easy I swear.

You could take a look at this thread by Carrot or just read this part:

- Use a descriptive thread title - You don't need a catchphrase or a leading question, or worse a completely ambiguous title such as "Somebody help me please," "Newbie question here," or "Looking for a flashlight" -- instead, focus on the basics, and summarize in a short phrase what you are looking for. This helps you to target people who know what they are talking about. Good examples might be: "Small CR123A-based light, under $100?," "Please explain different LED types to me," "Need a serious headlamp for caving," or "Aspherics $200 and less."
-- Also, in your post, try to make the first line as descriptive as possible. (thanks Kestrel)

If you do this it'll make the forums a lot more enjoyable for all of us.

It's easy, I swear!

Hey 65535, are you asking for help, advice or just letting us know that you'll be doing what should be considered a big job on your lathe?



Looks like you will end up with a big pulley and a little one. Which are you keeping?

Re: It's easy I swear.

Actually the smaller part will be scraped, so I saw no point in keeping it, I actually think at a 5/8" bore the last smallest step would be mutilated.

But OH BABY. 3/4 Horse for a lathe that requires less than 1/4. It works out about $50 cheaper than a 1/4 horse and VFD, believe it or not.

BTW I need it done, still have no power on my little guy.

Re: It's easy I swear.

What's the dimensions on that pulley? Diam will probbaly be enough.

Re: It's easy I swear.

Edit first post, it's pretty darn small, I could do the work if I had the power. Heh.

Re: It's easy I swear.

I'll be unavailable for a week, but if you want to wait that long, I'd do it for you. Well within the capability of the 7x12 lathe.

If someone else wants to do it, by all means go for it.

BTW, since the Taig is so small, you could acually power it with a corded power drill that is hose clamped to a piece of board. The existing pully would then fit on a mandrel clamped in the drill's jaws. That would work long enough to get the center hole bored. It might even last long enough to face it too.

Re: It's easy I swear.

That is true, but I still need to order an indicator and arm since I have a 4 jaw independent chuck. So I figured if someone could do a quick bore and face for me on the cheap it would be awesome, I considered getting a keyway cut, but that would lose me another groove or two, and probably require sending to Barry, and he's a busy guy.

Do to geographical location, I'll probably take you up on the offer Daniel, or see if dark_zero might be able to with his giant 12xomg huge size lathe.

Re: It's easy I swear.

Did you get this taken care of? I see no packages in the mail. Dark_zero doing it?

Re: It's easy I swear.

Dark_zero doing it?

Nope, not me. I would have been more than happy to help out with this but I'm not the type to step on anyone's toes.

Re: It's easy I swear.

Sorry Daniel, waiting on a paycheck on the 10th then I'll get to the post office with a couple of things. I figured with your holiday and all the wait would be ok, if it's a problem we'll figure it out. Thanks for keeping up with it though.

 

[gadget_lover]

Re: It's easy I swear.

Oh, it's no problem at all. I just wanted to make sure nothing had gone awry.

Re: It's easy I swear.

Other than being broke until the 10th things are going ok. I should get it off Wednesday or Thursday. I'll write a note but it needs to be a thou. or two over .626"

I considered getting a keyway cut, but that would lose me another groove or two,

Happy to do that if you want. In aluminum, as long as the bore is standard (inch) and the keyway is also standard, it's a ten minute job.

My Siberian Husky can almost do it by herself, but has trouble with those little shims

 

[65535]

Having a keyway would be just awesome except the keyway would slice through another pulley or two. Which isn't quite acceptable in this situation but would be cool. Thanks for the offer.

 

[precisionworks]

Another option is to use a transfer punch to mark the set screw locations on the shaft & drill shallow depressions that allow the set screw to seat. Anything around .100" deep seems to work well up to 3hp.

 

[65535]

I figure since the motor has a keyway, that in the off chance the pulley tries to spin (normal power for this lathe is less than .25HP) the set screw will slide into the side of the keyway and bind there.

I like keyways, but I lack the room, unless there was a good way to cut a "blind" keyway.
