My not-quite complete FHM.
(Newly renovated, but parts are missing. It was repurposed by previous owner, who modified it and removed some parts and left it in quite miserable condition.
So i took care of it, but not quite sure what to do with it. I clamped a hi-speed spindle onto the...
Indeed, even my OCD had to dodge this one. Truth is, the gears just don't fit in my very small hobber. And even if they did, there is a time crunch to deal with. Low demands on the part... So, waterjet it is.
Thanks a bunch.
Hi. I need a few simple low-precision gears. I intend to ask my waterjet guy to do them.
But, I don't do CAD/CAM, and he likely does not speak gear or have gear software.
Does anyone know where to find a downloadable model or file with which he can cut a 3 mm thick, 54 tooth spur gear in either...
You know what, though?
They were actually interactive, or semi-live. I found them at the Wayback Machine internet archives. You could click topics and browse around. I’m not sure what would happen if you actually tried to reply to a topic, if it would just error or maybe pop up here instead, as...
As others have said, this sort of discontent comes with every update. This is what, the fourth or fifth update now?
Does anybody have a screenshot of what it looked like twenty years ago, when it was all sort of a pale yellow?
It would be fun to see.
”…If I rotate the table to the lead angle…”
Taking a chance by posting before having morning coffee here, but I would say no.
But, if you swivel the dividing head to the lead angle of your desired helical gear, then yes.
So, table angle = direction of travel = lead angle of hob. Always...
JB Weld is a very good answer, esoteric or not. The regular, standard, original version can happily withstand 400F. I know it does; I have tried it. Can't speak to the other new, improved (?) varieties of JB though.
Really interesting; i’m glad you brought it up. I have been wondering about this for years.
A while back i was at a ball bearing seminar put on by one of the major manufacturers. The guy leading it had been employed as a specialist turner & grinder at their HQ Factory.
So, i asked him. He said...
Okay, i had a second look and added a couple more pics here. I named three shafts, or pivot pins really, that matter here, and made a little sketch of how it works when viewed axially from the left.
Note, hinge or pivot pin A ends flush with brake band lever. Pin B has no function at all. Pin...
Okay, here you go: i took a bunch of pics, at increasing closeness to the item, with the last pic from above, inside the cabinet.
I also checked the manuals and so on for a drawing or schematic, but there wasn’t one.
Here is a link, to keep from spending Don’s forum bandwidth:

Damndest thing... y’know, I actually have one. With complete foot brake.
Now, i have no idea what you need really, but sure, i can have a look, take some pictures... Absolutely.

And if all else fails, just go find one somewhere else and copy-paste it. The good thing there is that it works on almost any device with any symbol or alphanumeric character.
EDIT: on an iphone, holding down the zero makes a ° alternative pop up. Holding down letter keys presents alternative...
Not sure about that either as it seems the absorbency would be very low, but i do know that applying oil to cut edges and surfaces darkens it and visually brings out the grain and structure, similar to wood. Makes it look great, really.
