Q on broaching 1/4 slot in aluminum
Success! Either beginner's luck or aluminum is easy to work with. It took very little force to push the braod through. If fact, I didn't even use the handle to pump the hydraulic. I just did it by hand so I would be sensitive to load changes. I did put the collared bushing 'upsidedown', so... -

Q on broaching 1/4 slot in aluminum
I am going to try a practice part before stoning. The stoning would be like in attached (with stone moving perpendicular to paper)? That would reduce the rake angle... -

Q on broaching 1/4 slot in aluminum
Thank you guys. Starting off with the file to remove most of the 'meat' sounds like a great idea. I plan to be real careful with the hydraulic press. -

Q on broaching 1/4 slot in aluminum
Thank you, Guys. When you stone the braoch tool, are you doing one tooth at a time, like this? Gbent, I had already ordered a broach tool or would have taken up your offer. Thanks. -

Q on broaching 1/4 slot in aluminum
Thank you for the tips/suggestions, all. It sounds like trying a few practice parts is a good idea. Guythatbrews, can you point to a diagram that shows what you mean here? “The solution is to stone a small land to decrease the rake angle a bit. A few thousandths land will do it.”. I’m not... -

oil furnace sooting extensively
Some guys say they can set them up by eye (by looking at color of flame, etc.). I bought a digital combustion analyzer to do my own (and smoke tester). It sounds like you're running too rich. Have you tried opening up the air shutter more? -

Q on broaching 1/4 slot in aluminum
I did look up rotary broaching and while it is fascinating, the tooling is more expensive and it looks like you really need a CNC lathe... Thanks, Gordon. -

Q on broaching 1/4 slot in aluminum
I do have a small lathe (Sountbend 9") and while I could probably do it with hacksaw and file, I'd prefer to do a neater job and broach it. -

Q on broaching 1/4 slot in aluminum
I searched through the forum for this subject but didn't find an answer. I haven't done any broaching before, but now need to add a 1/4" width slot in an aluminum hub (steering wheel hub) for my antique car. I have a hydraulic press and have watched videos and understand the basics of what's... -

Adding thread dial to 9" Junior?
Thanks! I like that idea as I’d rather not drill into the apron either.- Mike C5

Adding thread dial to 9" Junior?
Come on guys, someone here must have a machine with dial as originally installed. This catalog screen shot seems to show a bolt. Is there a permanently mounted pin (on apron) in lower hole of bracket?- Mike C5

Adding thread dial to 9" Junior?
Those of you who have a 9" Junior with thread dial attached as shown. Is the stud and pin arrangement like the photo below how yours is attached? I drew up the basic dimensions of this area in AutoCad and would much appreciate if I could get some feed back on where to place the holes and what...- Mike C5

Lead screw binding when thread gear nut tightened
I looked at it again after realizing that with the large, fine feed gear on there (that came with the lathe), I had no such problem. I tried cleaning up the thread gear and now it works.. Maybe a little surface rust was doing it... The other thread gears seemed to work ok too. Strange...- Mike C5

Lead screw binding when thread gear nut tightened
I did some searching on the forum but didn't find an answer to this. I finally bought some lathe change gears for my 1933 vintage 9" Junior and tried them out. I noticed that when installing the lead screw gear and tightening the nut, there was binding between the gear and lead screw bracket...- Mike C5

Adding thread dial to 9" Junior?
I can imagine hard maple making a good gear for this application. No doubt it would be a fun project but I think I'm going to go with one of the 3D printed ones for now. This one has the bracket that looks like the one in the 1931 catalog.- Mike C5

Adding thread dial to 9" Junior?
Thanks John, That's interesting that it has a bracket cast as part of the dial body parallel to the edge of saddle. I get the feeling that isn't a very common configuration. Looks like I'm going to have to improvise.... I did some more searching and found this but I'm not sure the saddle is...- Mike C5

Adding thread dial to 9" Junior?
I have a 1933 vintage 9" (Junior or Heavy as I understand it) and would like to try learning to cut screw threads with it. I have change gears but still haven't acquired a thread dial yet. I notice that most of the thread dials attach with a pin into a boss on the edge of the cross feed...- Mike C5

Question on die sizing for rectangular tubing bend
Thanks guys. I came to the conclusion that I would need to 'burn' some material and experiment. I machined the die down to 2.4 R and that did achieve the desired effect; close enough at least (I had to take small steps to avoid having to buy more material to make another die; no going back if I...- Mike C5
