|Thread: Bantam thread cutting set-up?|
You say it's an Eagle that makes it a Metric machine. You use the compound for inch thread, but use the 127 as an idler for metric I believe.
|Thread: First lathe|
Some people will always resist technological advances. For me, anything that improves ease of use and reduces risk of error is a good thing.
Fitting a DRO will transform your use of a lathe. I don't know what type you'll get as a £200 accessory but my £300 one has made a world of difference to how I go about working on mine. It will even measure existing tapers very accurately.
|Thread: Myford Mod|
It mirrors the lever on the Hardinge HLV-H so I tend to agree with Keith.
|Thread: Cast Iron Grade 500-14|
500 grade SG iron shouldn't be a problem to machine. This is 600 grade and it came out beautifully.
|Thread: What lathe tool for deburring holes?|
I use a broken 6mm carbide end mill shank. I ground a 90-degree point on it then ground it flat across the diameter. Put a tiny radius on it and set it into a piece of cold rolled with a grub screw to hold it.
It does inside bevels, outside bevels and it'll take light facing cuts.
|Thread: Higher trolley for surface plate?|
Well I keep my granite plates standing on their edge, and I have the means and ability to check them when sat on their 3 feet. So far none have taken a set from being handled or leaned.
I think we need to get some perspective here. The portable plates we tend to use are shipped in a timber crate by regular courier. They aren't going to take a set from vertical storage.
Actually Robert, I was referring to this
and I would contend that a portable surface plate sitting on edge is less likely to be affected by gravity than one sat flat on it's feet. I also don't believe that bringing one from upright to flat or that any other normal handling could possibly affect it's geometry (unless you dropped it). I carried mine to a scraping and alignment class on the seat of my van where it was checked with an autocollimator and found to be in good fettle.
I couldn't comment on how the one left leaning against a wall ended up bent, but I'd expect that a 4' x 6' x 6" plate would require good support and adjustment when mounted horizontally in order that it wouldn't bend under it's own weight. My 18" x 24" surface plate is 4" thick giving a 1:6 thickness to length ratio. The plate mentioned would have a 1:12 thickness to length ratio so much more bendy - twice as likely to bend as one which is small enough to man-handle onto it's edge.
I'd like to hear the reasoning as to why a symmetrical shaped piece of granite stood on one flat edge should be any more prone to warping that one stored flat.
This is what I do. It uses very little space and is easy to deploy into use. Mine just sits there on it's long edge face against the wall.
|Thread: How Best to Sell a Clarkson Cutter Grinder & Accessories?|
For the best return you could list each part separately on eBay. The late clarksons are well sought after and the accessories make very good money. Most of the tool dealers sell the machine bare and the accessories separately because of the money they make.
If you're keen that it should all go in one package and want some valuation advice post the photos in your album here and see what people say. Expect to get a raft of personal messages from people trying to cherry-pick the high value stuff though.
If you're going to sell it complete then www.homeworkshop.co.uk is a great place to list it for free.
P.S for your chisels look around for a viceroy sharpedge.

|Thread: Engineers' Level adjustment - why 4 holes?|
I would expect that the outside holes are threaded into the vial carrier so those screws 'pull' and the inside holes thread into the housing so they 'push', thus allowing adjustment with the facility to hold the vial very firmly. If you loosen either outside hole too much the vial carrier will fall off the screw.
|Thread: DC motor reversing|
As a lifting device for the disabled, I'd say it has a brake that is held off electrically and fail-safe's to 'braked'. Probably under that copper strip.
I'd start with pulling out the motor and testing it outside the housing. Certainly don't test it with 24V if it's wedged with 12V.
|Thread: Myford Apron Dovetail Damage|
Make a burr file and get rid of any high spots then just use it. Take an ordinary thin flat file and rub it on a stone a bit to take the edge off the teeth. Now run the file flat across the dovetail surface. It will only cut high spots and leave the way surface unharmed.
|Thread: hardinge 5c collets|
Hey Barry, thanks for the long reply and especially the excellent test specifications. I'd love to continue this conversation with you but this is not my thread. Perhaps when I get some time I'll start one about my own HLV.
P.S I actually had those very test bars you mention in my workshop for a time. I was storing them for the guy who bought them from ZMT. Alas, I didn't have my machine built before he came to collect them but that's ok, I can make my own.
|Thread: Pratt Burnerd chuck|
What are the jaw width, slot width and tooth pitch?
|Thread: hardinge 5c collets|
Thanks for you r detailed information, it's great that you have been able to provide some insight into the production of those collets. Tight tolerances indeed.
My interest comes from doing a full restoration of my own Feltham HLV. I had the bed ground and rebuilt the carriage, scraped the various ways and rebuilt the headstock too.
I have a question to ask of you - can you tell us what it is exactly that defines the KL-1 model as opposed to a HLV-H? Is it just a UK designation for a HLV-H? A metric machine? I can't seem to find a definitive answer, I'm hoping that you know.
|Thread: Boring problem|
Try making a boring pass then simply pushing against the tool post with the heel of your hand as you retract the tool. Chances are it won't even touch.
|Thread: Hammer flipping experiment?|
I can debunk that now Dave.
I just found an old wooden mallet. Typical symmetric head and rectangular-ish haft. I took a marker pen and wrote 1 and 2 on the opposite faces. A and B on the opposite cheeks.
Every time I flip it with the 1 face upwards, I catch it with the 1 face upwards. If I flip it repeatedly starting with the A cheek upwards, it flips to B, A, B, A, B without fail.
|Thread: Ac motor 3 wire|
I took a motor out of a security barrier once that was wired like that. It's a 3 phase 415v motor but wired to 240v single phase with a capacitor wired across 2 phases. Up and down was provided by sending power to one of the two phases wired to the cap or the other, as required.
For light duty operation it works just great.
