Re: Rattle in my milling machine quill

Good to hear it wasn't anything more involved or expensive Allen. You got a bit lucky. Now that I have been in it, there is not much to it. I guess if the head were worn out, the quill could be moving sideways in it, or I might have to change the tapered bearing, or the spline at the top could be d...

Re: Rattle in my milling machine quill

Gentlemen, I took the quill out and took the spindle out of it. I was cursing it all along until I removed the aluminum ring at the bottom of the quill that covers the hole that the screw for guiding the collets goes through, It is like a key for them, but a screw through the spindle, with a bit at ...

Rattle in my milling machine quill

Good day gentlemen. My mill, a ten year old Grizzly 3617 has quite a rattle in the quill, before I take it apart, I wonder if any of you have a suspicion as to what it might be. For what it is worth, it does not seem like a bearing. Thanks.

Re: tap drill/bore for 2-1/4"-8 tpi thread

I have made a few backing plates for my lathe, which is 63mmx 8 TPI.. I bought the lathe new, and it came with a couple chucks, which had factory backing plates. I entirely cheat, and just measure the ID of the factory ones, and bore to that. My lathe has a shoulder on the spindle, and I am careful ...

Re: Gear Repair.

What I did: I ordered the correct involute cutter from Travers, and waited a few weeks for it to get here, I presume it rested at customs for a while. I milled out the broken teeth, and brazed up the gear to cut the new teeth in, also filling the teeth to each side of the damaged area. I made and ar...

Re: Gear Repair.

I have rotary table, with a 4 jaw chuck on it. I have the indexing kit for the table, although 9 degrees is not that difficult. I could turn an arbor for the gear in the chuck, and center it there. I would buy an involute cutter, I just need the number 3, I have considered a few repair techniques. F...

Re: Gear Repair.

Yes Harold... I could broach one on the lathe.. I knew that, I am considering buying a involute cutter, now that I know which one I need, and making a gear. I went down to the Boston Gear dealer here, and he confirmed that it is a DP 16 with 14.5 degree pressure angle, before he confirmed that Bosto...

Re: Gear Repair.

I may wind up fixing this one, or making one, or getting a quote from a custom gear maker. This is a 40 tooth 16 DP 14.5 Degree gear, with .750 face, and .875 bore, with a 6mm keyway broached into it, with a boss on each side, making the through hole length 1.237" , The bosses have an OD of 1.2...
