What did you do today?

[Cenedd]

I do love the way that as you get higher voltage and current, there is more and more insulation....until a point where someone just said "Nah, a nice big air gap and the threat of a painful death will keep people safe!". To be fair, it works!

Interesting bit of kit Paul. Cheers.

I got this in the mail. This one page is the entire instructions for putting the power feed on my mill. I can only hope that I can find some better instructions before I start disassembling it.

Wish me luck!



Oh.. the parts look decent. The cast part has a nice flat grind. That's not counting the couple of minor pits that are fairly shallow.



and, of course there's the box 'o' parts.

Dan, may I offer a helpful suggestion?

At the end of the project, there is a profound difference between spare parts and extra parts.

Glad to help.

LOL! That's a perfect response! Thanks! Fortunately I will have a week to find better instructions before I have a chance to do any work.

P.S. Now I know that someone reads my tag line!

Thanks. They appear to be the same, but in real English!

Got the shaft out today, finally. The gears themselves looks almost completely unharmed, there is a burr on one of them but otherwise they all look fine. The shaft is messed up

Here are some pictures of the shaft, as you can see it's plenty damaged, the threads on the front are completely obliterated from the pushing tool, it was really stuck in there good. So now, time to consider repair options. I have some ideas.







I've measured all the basic dimensions and put it into a CAD.

why not just re thread the shaft, or is a bearing seat worn down..?

[MattiJ]

I would probably part the shaft next to the thickest part/bearign seat, bore for something like M20x1, turn oversize piece of shafting and fit it in the hole with strong Loctite and after that turn/machine rest of the features. Only one key slot that you need to mill

[DennisCA]

That's precisely what I had been thinking actually, though I have been asking around for opinions if someone would have a better idea. But that solution is the one I think is best so far.

No need for loctite. 0.001" per inch per 100F. Stick one part in the freezer and the other heat to 300F. A shrink fit is 3 times more resistant to movement than a press fit according to my Machinery's handbook.

Also, if you did remake it from scratch, that part is begging to be done with a rotary table, a chuck, and a shaper.

Yesterday, I tested (sort of) the 10 hp motor I picked up to make my RPC. Clean Baldor motor at auction for $25! It runs well on 1 ph if I spin it up, so I'm going to go ahead and buy a control panel to start and run it. I could build one, but I like the plug-n-play aspect. If the weather ever cools off (shop isn't A/C) I'll be making chips soon!

Where are you located it is -5c here this morning.

wish you would send some of that cool weather down here. It's already 90°F today.

South Carolina. It was 96 F. (36 C) the other day. WAY above normal for this time of year.
