Pete, I'm not posting this to bust your chops...it's just that you were one I hoped would go digging! |

How the H did I miss that! Sorry Greg! I do remember something about fine thread and coarse thread! Is it the threads per inch or the size you are having a problem with? The Mcmaster book is always open on my drawing table because I use them so much at work. I do find there web site one of the better ones for searching out items. I'd be happy to take a look. Some items are easier to find out of their book.
My mind must be slipping again or maybe it's the recent CCfan events that have it all screwed up!!! |

Pete, you're all over for everybody(which I commend!). I can see where you might miss a dumb 'ol buffalo post. LOL
McMaster has what I need in the wrong material or the right material and wrong threads. What I need is 3/8x24 with a flange in aluminum(what I got from Greg), brass or stainless. Pete, this info is what I found on their web site...your assistance in the catalog is MUCH appreciated!!! |

Sorry to butt in. Greg, I have looked hard for the right inserts. The only option I have come up with is getting 5/16 aluminum with a flange, then drilling and re-tapping to correct thread

Bj,
I don't feel there will be enough wall to drill and tap the 5/16 out to 3/8. 3/8 is available. You would be better off getting a 3/8-16 and running the 24 tap through it. There's enough threads on the shifter arm to handle the load plus we aren't bolting down a cylinder head here!! Greg, You're correct that the 90016A034 is the only insert that I too can find with the 24 pitch. Yes it's brass and the screw in type but why don't you like the screw in? With the screw in I feel you would have less chance of splitting the wood. Take a look at 92105A420. These happen to be the same ones I've used. The last time was for "T" handle fastening the router table fence I put in my table saw extension table. I used 20 of them for muliple fence locations. These are the zinc/aluminum, with a flange and 33/64 length. (plenty of thread length) However, we're back to the pitch thread being coarse (16 pitch) but running a 24 tap as mentioned I feel will work. |

Oh well...
Thanks for taking a look Pete. Maybe it's time to check with Eric's machinist friend? I don't mind the screw-in or self-tapping insert, except that the part # I have has closer threads. It's not very forgiving on the harder woods. As it is, I'm drilling with a 33/64 bit when McMaster calls for 1/2; and then making threads in the blank before installation with epoxy. And no, I haven't had a single one break loose on the lathe yet. I should have called...this is tough to describe when I know we have creative Fans waiting for me to step in it! |

Yep, either way, like you say we are not bolting down a cylinder head. I thing that gets me though is that some one out there has the exact part needed. I just have not found them.
Further, It is the challenge I groove on. bj |

Greg, Good morning, Did you see the thread where I mentioned going to the lake for ten days? It has rained hard every minute since. I am thinking the lake has come up 10 to 12 inches.

And a good morning to you! I did see that...I posted that we just got back from the lake.
We have also gotten a lot of rain this year. I've had to move my dock in several times. Right now we have 30 mph winds from that tropical storm. Aren't those supposed to go to LA first? |
