Thread: aching ribs - posture

Hi mick.

I have some aches and pains, I found a good book on my kindle called The trigger point massage therapy work book"

It gives simple self massage techniques to ease the knots in muscles that can cause all kinds of pain. Nothing more complex than a tennis ball or massage cane and you can ease all kinds of niggles.

Well worth reading and giving a go after a hard day in the shop.

Best regards Mick

Sounds like a good tip; can you confirm that it is the book by Claire Davies that you recommend, please?

(There are a number of titles with similar names).

Could the slit be left incomplete to prevent the casting closing up too much due to released stresses?

MichaelG:

Thank you; you are the master of the LINKing art!

Mike Poole:

Tap and test should not be necessary with the Smith gauge but if needed the GHT-style adjuster is a great help:

(The "topslide" in my picture is actually an ML7-style cross slide which is good for longer tapers).

I set my topslide to machine my ER25 spindle nose adaptor and got it spot on first time, unfortunately I doubt that I could ever do it again, sometimes you just get luckysmiley

Mike

You could if you made and used a Smith taper gauge; see my posts in this thread:

No problem with the Myford screwed on chuck when I did it:-

Light bulb moment: running the tool upside down at the front would deal with my visibility problem - thank you!

Jason B:

You have not mentioned this in vain.

However, the direct import Chinese tool-holder I used to try this would, I think, only be usable with relatively short threads. I was surprised by how well this method worked given that the tool seems to be working the wrong way round in relation to the helix angle of the thread.

I found also that the work is more difficult to see working like this and it was obviously necessary to be very disciplined about moving switches and levers in the appropriate direction.

Roger King 1:

Here is the photo I promised:

dscn1563.jpg

Each jacking screw cum raising foot consists of a length of large diameter studding with the upper end tapped 5/16" BSF, a short cylindrical foot of about 1.5" diameter, two nuts to suit the studding and the 5/16" hold down bolt and washer. The lathe foot sits on the adjustable upper nut (not on the studding) and is held down by the bolt.

Thinking about this at many years' distance from when I did it, it seems clear that the cylindrical feet must be tapped to suit the studding, the lathe tray and underlying structural member being firmly gripped between the foot and the bottom nut.

I hope this is clear!

Thanks for the continued advice, much appreciated. I can find the post by Peter Shaw, but whilst a solution is mentioned I can't see a description of it.

Thanks for your description Howard - it sounds from the detail as though your lathe is actually suspended on the threaded rod resting on the nuts - is that correct? Probably need a fairly substantial thread size for the weight.

I have sent you a PM

This post by Peter G.Shaw refers to my favoured solution:

I have a variation of this method on my Super Seven: it is effective and a good deal cheaper than the Myford offering.

It's normal for the initial interrupted cut to be noisy. You could consider taking off the flats with a front-mounted HSS tool at slower speed and then move to the RTP at your favoured speed and feed.

Interesting that after ten years you are still using the same blade which suggests that the machine has been very lightly used.

Incidentally, I assume this is the Warco product.

Are you using a suitable cutting oil or paste?

I would certainly try the collet.

How about screwcutting?

The "spare jaws" for the three jaw chuck are likely to be reversed configuration jaws which allow larger items to be held.

Good luck with your machine; it's seems to be well-equipped.

Good idea but could you buy an electrical appliance in such a place?

Yes PAT stickered ... from some of the more enlightend ones.

Good to know and a relief from some of the overreaction to safety legislation.

Belt the rightway around? They have a proper direction of travel.

Namely? I have been wondering about this myself.

Thread: Bolted or Feet?

Posted by Rob Rimmer on 26/04/2019 16:37:18:

Just to sidetrack the thread slightly (sorry) - where is a good source for decent adjustable feet? I only seem able to find very flimsy pastic ones, or ridiculously expensive ones that would hold several tons.

TIA

The set of four supporting my (unbolted) 500KG lathe came from Warco.

Incidentally, that weight does not include the ballast I have loaded into the cabinet.

Before getting a larger lathe I made and fitted a 9" flywheel to the quill of my mill/drill. This was made from black MS but the idea came from someone who had used a brake disc for the purpose. Mine was faced on the Super Seven by bolting to the faceplate. The finish is adequate but far from perfect:

Another job in the Myford just fouled the ends of the shears and I confess I trimmed them to clear it:

This is not to suggest that I would encourage the OP's suggestion!

Thread: Model Engineer's Handbook printing error
20/04/2019 11:15:07

Despite these apparent faults the book has an impressive printing history and I note that it is bound in "signatures", a sign of good quality, although the method does perhaps facilitate this kind of fault.

As a reference work, it seems possible that many will never notice or suffer from its omissions or duplications.
