Something satisfying about seeing a gear cutting video, I guess it’s just the precision of the whole part.

I can see runout in the arbor shaft, like watching a jumping rope. You might want to set that shaft between centers and check the runout in the center. Fine video as always!

I thought the same thing. Worth checking, but it might just be the spacers running out

@ellieprice363

This type of setup always runs out due to the accumulation of clearances. The long shaft has some runout. The cutter bore is slightly larger than the shaft. The cutter OD is not perfectly true with the bore, and the bushing the shaft runs in has some running clearance. All of these tolerances cause cutters on horizontal shafts to run slightly eccentric.

This was so cool... Would really love to see you machine a Herringbone gearset.

I think that your arbour is slightly out of true, hence perhaps the uneven cutting? You can see the out of true in the video. Try rolling it across a flat surface to check and you could apply the Keith Fenner straightening method?

Nice work as usual, I enjoy following along it’s nice to see old equipment being kept in repair and in service still functional!

Very nice work Keith.

Thanx for the video ! Always a pleasure to learn from you. Please keep up the good work and I am looking forward to the next.

Hello Keith. I live in the UK so I will probably never be able to get to any of the meets you go to so it is unlikely that we will ever meet which I feel is a shame for me. I just want to say that I have been watching your channel for a long time now and I enjoy them very much but, also I have noticed how well you look at the moment. It’s good to see. I wish you well and I will continue to enjoy your posts. Best regards. John Greatorex. Derbyshire, England.

As a former jet engine mechanic, like you, we didn’t reuse bolts or cap screws as they were already stressed and stretched from original torquing.

Looks nice!

thanks Keit

Good job

Excellent job Keith. After watching the vid numerous times, my eye picks up what I believe..... is that its NOT the cutter itself that has the run out, but the cross bar instead that appears to show a 3/4 thou to 1.5 thou runout/oscillation.....its clearly visible in many of the longer full frame sequences......its just enough to show a rhythmic up and down oscillation of the bar. Excellent excellent job as usual despite this minor problem....... Don

KEITH, GREAT JOB AND GREAT VIDEO...LET'S GO TO WORK...

Thoughts going back and forth between "geez, that seems like overkill" and "somehow those gears got chewed up". I hope the future of the drill press is better than its past...

Good Morning Georgia!😊

Tisk Tisk Keith, 10-32 is a #21 drill. Just giving you a hard time ☺ Great video as usual!

Great content as always. I know video can cause optical illusions such as wheels moving the wrong direction, and color differences on a rotating object can make it look like it is wobbling even if it is not. That said it does look like your arbor is bent which would explain the excessive amount of runout you were experiencing from that cutter.

Not criticising him but moving everything closer to the body of the mill and taking out some spacers and shortening the arbour would make things stiffer.

@LeonardRoberts

​@Chris Stephens was thinking somewhat the same idea, seems there is a potential for an error with each small spacer, even if had larger spacers might reduce error possibilties and stiffen the arbor shaft.

At 9:27 when the lathe slows to a stop, it looks like the hub is very off centre compared to the lathe setup? Looks like about 40 thou off? Wasn't it important to get the gear concentric to the bolted hub?

Correct me if I'm wrong, but I believe too slow of feed rate can cause a cutter to sound non concentric because the cutting teeth don't maintain contact throughout the cut.

Good morning

The clearance holes should have been all the way through the steel gear blank with the threaded section in the cast iron. It sounded like you only did the clearance deep enough for the counter bore. You could use an end mill bit to do the counterbore.

Should also oil the back side of the broach where it rubs the shims. I expect there's a lot of friction there.

Nice job Keith.

looks to me that the arbor that the cutter is on might be a little bent to make the cutter seem to be off center. looks like no problem with all the other work!!

Keith, how did the helical cut timing gear for that engine work out? Did it work ok on the engine rebuild?

37 is prime, so aside from that the next hole patterns you could use would be 74 or 111 holes.

Question that heavy cut one side could that be so you have a relief cut for chips to clear out? And how do you cut internal splines to make a coupler for two shafts?

Hiya Keith

You would think by now Keith would have every single size of every single drill bit... but there's always another.

I was surprised to see you cutting the gear while locating on the outside diameter. The gear does not have to run concentric with the outside diameter, but with the bore. I spent 50 years working in the gear and gearbox industry. However if noise and vibration is not an issue then what has been made is adequate.

Nice!! 🙂

I know you can always work around and get the depth you need but it looks like you arbor the bent on that gear cutter. May want to check it with a dial indicator if the runout bothers you.

Is there a timing component between the two gears? Does it matter where the teeth start?

I imagine these gears are from the feed mechanism, if so the worst that can happen is that the lever/wheel/crank used for manual feeding ends up resting at a slightly different angle...

I need some splines cut on some transmission parts, this something you would be interested in ?

I'm not sure if he has said before but once he is do e with cutting a new gear does it have to be heat treated.

I noticed you used cutting oil to cut the gear teeth, but not when drilling and tapping the holes. How do you decide when to use oil? Also, do you recycle the cuttings from the various metals and machines? Thanks....

It looks like there's excessive runout on that arbor - is it straight?

Its funny how many people quote tom lipton. Hes an intelligent fella!

@16:20 or so. Is it just me but does that arbor look a little bent? I know with the spacers that might be an illusion... 🤔
