Mini Lathe Motor. Again.......

[Stilldrillin]

.....Just needs a pelmet, or something, to keep the swarf off the connector block.....

David,

could I just suggest, whilst you're in "pelmet mode" it might be worth looking at the drive end of the motor as well? As I recall, you mentioned that the airflow was inbound at the pulley end, and from the belt shot above, it made me wonder if one of the suction slots might be exposed....

Hi Dave!

Do you mean, to stop swarf entering here?




I reckon I could hang something from the two motor height screws, which would cover both areas. 

Thank you, for the nudge.......

......I reckon I could hang something from the two motor height screws, which would cover both areas.  ....

Yes, that's what I was wondering about - might be a worthwhile precaution (save a few snap, crackle & pop moments!)

cheers / Dave

Dave.

I've had enough of those moments, to last me for the rest of my swarf making life. 

I'm on it!

The lathe's had it's first proper work out today. My standard batch, of 1 doz tokens. Plus one special.   




Orrible, extruded aluminium, from a piece of office equipment.    (Apart from the special one on the r/h end).......

Parting off this ally, is really taxing. Needing low revs, and plenty of lube.

The motor handled it all beautifully.

Clearing out the swarf tray, some minutes afterwards, it was a strange sensation, feeling the warm (aired) air, blowing from the duct......

Jobs a good un! 

Thanks for all your help, and interest Lads.......

Nice work 

[Stilldrillin]

Just a little addendum.......

I've been ploughing........ Roughing a lot of metal from a couple of flywheel castings.

Started at 5" diameter, with a 1" wide rim, alloy castings.......




Around 200rpm.
The speed control, set around 1/3 of it's travel. Which is not the best position for motor cooling......




Not a ha'p'orth of bother! Just ploughed on. Half a mill per pass, o/d. 30thou per pass, facing.

Motor felt slightly aired. Same with the extractor fan outlet. No alarming smells from the windings. 

The result.....




I reckon we've cracked it! 

Thanks once again Lads, for all your help and encouragement. I couldn't have done it, without you all out there.

David,
You may be interested to learn that a pal of mine in mainland Europe has just ordered a new motor for his Amadeal-badged Real Bull mini-lathe direct from RB in China.

On the other hand, you may be displeased to learn that, with shopping, it is costing him the princely sum of $53 (£33)   

Of course, he may have customs duty to pay when it arrives.

 He sure will

inc a £8 handling charge , import duty and VAT


just had one that was just over the threshold just about doubled the price , came in from the states

I think it was 33 dollars but the revenue dept included the postage in the amount and charged me on the whole lot

Andrew........ Sometimes, you can be very cruel, to a cautiously thrifty person like me! 

Incidentally. My original motor, is now in Portugal. Working well for it's happy new owner. Hmmmm..... 


Stuart.
I too have had to pay multiple taxes, + £8, on everything, including the £45 postage from Australia. Releasing the Huxtable engine cost me an extra £91!

Sorry, David! Still, if one had arrived from China in bits, like your last (but one) did, things might have got awkward.

The one I mentioned is going elsewhere in Europe. Similar imposts to those which Stuart mentioned may apply at its destination, of course.  Into the UK, it would be £33-ish + 20% VAT (£6.60) + £8 handling = £33 + £6.60 + £8 = £48 (approx). I think the threshold for import duty is £135. 

Did your original motor go to Jose M?

[Stilldrillin]

Did your original motor go to Jose M?
Andy

Yes it did Andy. Along with another alloy bell, + oddments.

He araldited the cracked fan blade, and skimmed the commutator. "...... and your motor is now running fine, powerful and smooth on my lathe."

Also he has adapted the alloy bell to the "plastic" motor. By removing the plastic shaft spacer. Though this mod needs a  bearing with different bore, due to the larger shaft dia......
He will soon have two working motors......
