Alf:

Drink a "sacred river" of snaps for me!

Thread: 3 phase motor

SOD:

Good to know and interesting that the country normally cast as the villain of the piece was first in the field.

Where's your quote from, please?

Virgin Flaxseed Oil (Linseed Oil) gives a nice durable finish to workshop tools. Clean the tools, rub it on, and bake in a domestic oven. No bad smells either!

Is that the same as raw as opposed to boiled linseed?

An attractive idea as long as the workpiece is not held together with Loctite.

Thread: 3 phase motor

Mike Poole:

Thank you; it's good to know some of the cost of a VFD is offset by energy saving.

Three phase motors for small applications have up to 8 poles, the more poles, the slower the running, so with equal horsepower, the torque increases the slower the motor runs natively. The motor I bought has 6 poles, the 8 pole one was 50% more expensive.

This is the one I bought:**LINK**

An interesting quote from the linked page:

"From Jan 1st 2017, three phase electric induction motors with a rated output of 0.75kW to 375kW and efficiency less than IE3 must be equipped with a variable speed drive (Inverter Drive). For exceptions, see EC Commission Regulation 640/2009."

Would anyone care to decode this for me?

Thread: Resilient motor mount retaining clips.

This group is so helpful.

Ega, you are correct with the bits, it's just the clips that I need, I've put mine somewhere safe...... 😂 Can't recall where it is though so I consider them lost.

If you want the clips,I suggest we deal with this via PM and/or email; I would need your address of course which I am assuming is in the UK.

I think hes refering to the clamp /clips with the nuts on that go on either end to fix the motor onto the cradle. Like in this thread.

Tony Scott:

I have a complete mount from a Hoover brand motor which might solve your problem; the between centres distance clip to clip is about 218mm.

PM me if you want to pursue this.

Thread: HSS tool sharpening
19/11/2019 13:59:33

The general run of bench grinders have inadequate tool rests for our purposes - flimsy and limited in adjustment - and it may help to make or buy something better.

Thread: Lathe boring tool - top rake?

Zan:

Good tip about the penny washers!

Thread: Quorn MK3!

See the Hemingway Kits home page.

Thread: Positioning bushes for welding
17/11/2019 11:09:26

I would tack them, check, adjust as necessary and then finish weld.

Thread: Ornamental Turning
17/11/2019 11:07:49

The Quick Step Mill or device with similar function will do some kinds of ornamental turning. The maker John Payne used to demonstrate this at exhibitions.

Thread: Record 25 vice handle
14/11/2019 13:44:58

I recall reading that Ettore Bugatti, who was as much artist as engineer, was in the habit of inspecting the jaws of his workers vices and firing anyone with file marks on them.

The handle is made from EN16T the original is forged in situ one end is heated and drop forged then put through the spindle and the second end is induction heated and forged. ...

This seems entirely credible. However, in Scott Landis' "The Workbench Book" the author (who apparently visited the Record factory) states that the woodworking vice handles were cold-forged at both ends.

Does this suggest the use of different steel for woodworking vice handles and that metal workers are more likely to abuse their tools?!

Thread: Extending router shanks
14/11/2019 11:24:44

This is perfectly possible:

dscn1689.jpg

My photo shows a standard 20mm 1/4" shank bit extended by boring out a length of 1/2" PGMS or silver steel and fixing with high strength Loctite. Apart from the extra length, this gives greater rigidity.

In deference to safety concerns, I would not do this if a suitable bit were readily available. Thus far, the extended bit has only been used to enlarge holes in 36mm thick MDF ie drilling.

Thread: Workshop series
10/11/2019 17:03:59

Plus one for SOD's endorsement; but some are classics and some perhaps less relevant today. My list of favourites would include one or more of Tubal Cain's titles, Martin Cleeve and Ivan Law.

No doubt some of the more recent titles are in the process of becoming "national treasures".

It would be interesting to know what the best sellers are.

Thread: Headstock Dividing Attachment from Hemingway
10/11/2019 16:55:49

Mark B:

Thanks for your reply.

I am no programmer and controllers are some way above my head. I am however under the impression that any number of divisions is possible with the HDA, using the micro attachment where the division plates alone won't do the job.

One of the first GHT items I made and has had considerable use.

Can you elaborate on your ideas for using it with a stepper motor, etc?

Thread: At last - no more chattering when parting off!
03/11/2019 14:26:30

Emgee:

That looks like the Mk 1 wheelhead and I notice the knurled clamp screws; is this so you can quickly swap out the spindle?

Thread: Boring bar toolpost.
03/11/2019 14:20:51

GHT covers this point in his Manual and is well worth reading generally on the subject of boring.
