Harrison Graduate woodturning lathe?

The late John Stevenson showed a design which combined lever feed with the original screw feed.

Mike Hurley:

Have you tried lever feed?

Hopper:

My recollection is that the vertical shears of the Super 7 bed were gang-milled rather than ground. My own, which was professionally re-conditioned but not by Myfords, seems to be milled.

I suppose practice may have varied over the life of the lathe.

PS Good luck to the OP with his task!

SOD:

I favour the expression shop-made over home-made when it comes to things made in the home workshop.

Garibaldi - which we used to call "dead fly biscuits"!

I believe the man himself was popular here, too.

I watched his excellent video at 1.25 normal speed.

I have a fairly distinct memory of being shown round a workshop with a long, induction hardened bed S7 many years ago.

Plus 1 for the step drill which will also deburr/chamfer the edges of the hole.

When I saw your drill table I immediately thought that it could be incorporated into GHT's UPT instead of the original minidrill design.

Can you point me to details of your own or Chuck Fellows design, please?

Janus words may not be what you had in mind but here is a small list of ones I made some time ago:

Janus words:
left - gone, remaining
oversight
cleave
mitt - hand, glove
scan
downs
best - worst (in contest)

Geoff:

Thanks for mentioning the adjustment feature. I prefer the hexagonal top kind as it is then easy enough to substitute a threaded (or tapped) component to suit the particular application; most of these handles seem to come in metric which is not always what's wanted.

Thanks for the tip. They look similar to those supplied by Eccentric Engineering with their Acute sharpening kit.

BTW, is your lathe sitting on Blu Tack?

Walnut blasting?

Hopper:

Congratulations on finishing the job! I hope that this thread and forthcoming MEW article will encourage others to adopt lever (or rack) feed.

Two points about the brass button:

Does it limit the travel of the ram?

If you sometimes use gauge blocks to set the depth won't the button indent over time and affect the accuracy? A hardened button could be substituted.

MichaelG:

Thanks for the link which, incidentally, reminds us of the possibility of registering our mobile numbers with the TPS (in addition to the landline, if any).

Would the corresponding part from the Hemingway Kits version solve your problem? (I don't know if they would supply separately, of course).

Thanks to whoever rotated the pictures which I would otherwise not have looked at.

Those magnetic bases do, of course, require something to stick to!

If you end up dismantling the box to any great extent be sure to get the cone of 16 to 32 teeth gears back in the right order (that point was the only issue when I did my Mk2 box; I have no experience of the Mk1).

Commercial tapping chucks typically have a collet to hold the tap shank true and a "two jaw chuck" to grip the square and provide the drive

How will a VFD fit in with the standard Cadet switching arrangement?
