Hey all

Continuing on from:
Scrounging in lockdown (playing with the lathe)

Lathe is running ok. For an old bench lathe anyway. Think I've got the chops now - guess we'll see.

Plan is to cut the starter ring gear mount (plus some) off the original P flywheel. Attach that to the VAPE flywheel. Then heat 'n' press the ring gear on as per usual.

Cutting the taper on the mount would be tricky. Very difficult to clamp it down another way - there just isn't much room or meat to play with.

Started by centering and squaring the og flywheel… +/- 0.01. Love me the 4-jaw.

This could all go horribly wrong. But time to throw some serious chips and attack the fins. Need them gone.

The 'teeth' easily broke off when I tried to cut them - worked for me, shifted a lot of material very quickly. Did wear one piece in the forehead and another up a nostril. Had some very decent safety glasses on, but figured standing back and to the side safer!

Need to take some measurements and plan this now.

Difficult puzzle with so many measurements. Having to make sure I have enough material so the part remains strong.

The 2mm step means I get all of 4mm beneath the groove behind the mounting lip for the ring gear (that the lip on the case behind the flywheel inserts into). And is only 1.5mm before the groove. Potential weak spot there. But to even get these I have to shave 1mm stepping down to 3mm off the VAPE, which leaves 0.8mm at the edge, and about 0.5mm at the step! Figure the stress will be going through the part not the flywheel (at those points) and the fins will keep those thin areas intact no problem.

Not sure if that makes any sense to anyone - but hopefully it will make sense soon.

Got a shimmy back in the lathe. Arghhh. Wonder if a bearing is toast or something. Seems to be cutting true enough so will box on. Too late now anyway.

Thinking of what my Vape flywheels look like, isn't there enough material there to machine it to where you can mount the e-start ring?

He's keeping us in suspense, SoCal-Project-Style

My best guess is that he's adapting the flywheel so it can sit over the Vape's actual flywheel, which is much smaller, and replace the Vape aluminum cover which provides the fins.

Intentional? Because at first I thought you were specifically giving me a reason for the mystery wobble - which may be on the money.

I have noticed that there is a lot of rotational runout/play in the main spindle. I can turn the chuck a fair bit back and forth before the spindle pulley at the far end does anything. Which made me scratch my head as assumed that those two things would be either end of a rigid system with no gears in between. Or maybe there's a worn keyway or something in there. The end-points seem pretty firm.

The x,y,z of the chuck doesn't move/knock at all as far as I can tell. But the wobble does seem to be a rotational oscillation…

At work all weekend but will have a dig into the manual when I get home. Suspecting any fix will be difficult, have to wait, and too late for this project anyway.

The backplate I made seems to run concentrically and the micrometer readings are reassuring.

The next drama is working out how to part this piece off. The parting cut needs to be clean as it will be a centering surface. Won't be able to refine it once parted. Doesn't have to be a precise radius - will only determine where to cut the corresponding step on the VAPE. Which for once I should be able to cut by actually testing the fit as I go. The backplate and motor pulley I had to rely on micrometer measurements because the area to fit was part of the running lathe.

But can't simply run a parting tool into the face as will bind into the radius of the cut with any depth.

Will probably have to clear a bit more material to give space, and hopefully use a boring bar to create a deep clean surface as far as possible. Pretty sure that step will be higher than the corresponding step on the VAPE - so the final parting cut should be clear and above (and also could be tidied up later).

Here's a vid of of the play in the spindle pulley. Manual says the pulley is independently mounted to "take care of belt thrust". Unfortunately doesn't tell me how to remove the pulley or if some play is intentional. Did some google searches and can't find anything useful. Will probably post on practical machinist…

Arghhh - don't want to try and remove the pulley without knowing exactly how. Hate tackling things like this because they tend to go wrong and something gets wrecked. Probably the aluminium pulley. Why can't there be a nice big bolt to undo, a grub screw, or even some thread for a flywheel puller type tool.

I do wonder if this has been significantly modified from the original. Just hope it's not something like the end of the spindle itself may have been peened to hold the pulley bearing.

I don't understand how a pulley on independent bearings turns a spindle without a connection like a woodruff key or something.

What happens if you remove whatever that plug is in the end of the pulley? It's designed to be removed, so what's in there?

Also, as I read the description, what they're saying is that the bearings, the shaft, and the pulley are three separate parts rather than combining (probably) the pulley and the shaft.

Given that they felt that was a selling point, have you tried googling around to figure out what the inferior design is to compare it?

I thought those grooves are in the spindle itself - guessed they are the keyways. Can't see a plug - it's like the bearing for the pulley is behind a lip on the end of the spindle shaft. But perhaps it is something itself threaded on the the spindle shaft - I'll look closer.

Also guessing that the reason for separate bearings is so the initial force from the motor hits the pulley bearings rather than spindle bearings - like they are sacrificial or something.

Not sure exactly what issue you are fighting that you want to disassemble?

There COULD be a pin that goes through one of the gears - that is intended to be pushed in and pulled out by hand.
This locks or uncouples that particular gear.
That is a system used by Logan as well.
It's to disengage the main drive gear when you are moving it in to back gear.
Is there a back gear option on yours?

My guess though is - the movement is designed in - to avoid stripping gears.
It introduces some give in case of something causing lock up - or the motor starting fast and jerking the system.

Posted on practical machinist - got a link to an Emco .io group. Joined that which gave me access to parts manuals and stuff. Practical machinist locked my thread because I'm just a lowly hobbiest with a bench lathe! Haha.

Seems like there should be no play there - that there is likely a key/keyway that is worn. Parts list shows a retaining ring - not entirely sure how it is removed but haven't had a chance to dig through the documents b/c at work.

Only reason I'm chasing this is that the oscillating force probably isn't helping accuracy. Bothered to try and solve it on the motor pulley - might as well try and sort the spindle pulley. Especially if it's as easy as pulling it off, sorting a new key, rotating the pulley 180deg b/c two keyways in the shaft. Probably won't be that easy… but worth checking.

Do have a gear reverse (for the lead screw). But nothing that pulls in/out - it's a lever system. Reverse for the lathe is just via the motor.

Actually my bad - they hadn't locked my thread. Just their UI sucks on a mobile and the reply button wasn't showing. But I did get warnings that it would be and directions to the stickies (basically die hobbiest pleb scum - we don't want your sort around here). They hated on me using a parting tool the way I did (thinking that I was somehow using the side of it to cut… sigh).

You should shove the EE10 in their faces. Still don't know how you managed to 'acquire' that (and the mill). Anything like that over here would be a fortune. Like Vespas - machine tools have jumped up in price thanks to covid (forcing everyone to take up hobbies). Ps - anthracite or gun metal grey for the EE10. The color it is now made pretty.

I'll join hobby if I get stuck again - have got the spare parts list for my lathe from the emco groups.io. Here is a cross section with the retaining ring highlighted. Can't make out any key for the pulley tho.

Wrecked after working all weekend. See if I can muster the energy to play in the shed. Otherwise tomorrow.

Poured a whisky and had a tinker.

1. Spring that must hold the pulley hard out against the retaining ring. This in order to keep the pulley in that position when you push the lever that drives the spindle forward (x axis). You can horizontal mill/drill with the headstock. Also mount the same headstock on the milling attachment I believe.

So many terms in machining. Crazy vocabulary.

2. There was a retaining ring with a groove and a corresponding groove on the end of the spindle. That wire was in the groove holding it on. Hidden beneath grime and even paint - can't have been off for a long while. Couldn't pry the ring off (broke a flathead trying… serves it right for being a flathead). Managed to pry an end of the wire out, and work along it until all out.

3. Wood dust…. That's a grease nipple hiding beneath it all. Ffs.. great place for it. Will free the nipple tomorrow.

So the spindle pulley has two keys. They seem loose in the keyways. Which do seem a little worn. Tbh brain is fried so I once I got it off I was done.

Better assessment tomoz. That whisky isn't going to drink itself ;P

Well I have no idea exactly what you are trying to accomplish - but we are traveling similar paths again it would appear.
Which is to say - I like freeing the nipple and scotch.

The shudder means I can't run in certain speeds - and vibration is bad right? Just trying to make it run smooth. And not wreck the bearings that seem to be in ok condition. Compared to the shagged pulleys anyway.

French Shutter??? Letting the missus choose the decor in the garage now? That thing is a weapon… ;P

Someone bodged the setup and made brass keys that were worn. Meant to be a plastic piece. Turning the keys around the other ends were too tight for the key way so I honed them down and reinstalled.

Getting it back on sucked. Had to push the retaining ring against the spring far enough to get the wire clip back in the groove. Much cursing, sore hands and sweat.

Just parted off. This 12mm cut took over an hour! Had to make a curved parting tool - round nosed. The cut is right where the the cast iron centre that I think must hold the magnets joins the cast aluminium outer. Needed oil when deep. Many modifications and sharpening of the tool. 100rpm. Compound... very slowly. So glad that's over.

That makes sense, except I'm still unclear on one major thing...how are you going to handle clearance?

Flywheels rubbing on cases has been an issue for me on almost every ignition swap. Are you going to space the flywheel off the magnets to make it fit, or how is that going to work?

At this point, I'm wondering if you'd have been better off cutting the inside out of the old flywheel to fit the Vape center.

(But then, what do I know. I don't even know how to use a lathe, much less own one )

I'm gonna hope that my measurements and calculations are correct… no chance to correct anything. Except cut the lip on the case. Which I don't want to do.

Yup… if I get this wrong then that's two flywheels down the drain.

Mounted the VAPE. So easy - just used the removal tool =)

Indicated from the spindle thingy. Not even +/- 0.01mm. Couldn't get the face perfect tho so that was +/- 0.05mm at the edge. Concentricity more important than being absolutely perfectly square so boxed on.

So nice cutting wrought aluminium at a decent speed with carbide tips. Been dealing with so much crappy stock up till now. Swarf everywhere.
