Thread: Acme internal threading

You can of course buy ACME taps which for a 5/8" dia thread might be a better answer?

Thread: Harrison lathe half nuts dont stay engaged under load
14/04/2022 11:50:49


I have a Harrison M300 which is fortunately in near mint condition.

In the Harrison Manual on page 98, IIllustration 94/10/2.Half Nut Part No 39, behind that Part No 44, Plate Bridge.

Also illustrated are parts 40 - 43 which appear to provide some form of Detent mechanism.

As the Half Nut Shaft, Part No 30 is inserted solely from the front of the Apron there must be a matching hole/depression for the ball and pad to contact. No obvious way to adjust, other than it fits where it should!

Note there is only 1 half nut listed, not a pair.

Regretfully only examination of the physical parts will provide a full answer.

Hopefully this will help you in some way.

Sounds a bit like Thomas the Tank Engine to me.

Thread: Imperial v Metric Measures
11/04/2022 15:03:33


I ike the nail as being a tolerance of a 1 yard measure. ie 1 yard + 1 nail.but apparently not - 1 nail.

Good measure aand not cheating.

V8Eng & DMB

Vehicle drawings and Jigs "always" use mm so logical to give vehicle size in mm.

Hobs manufactered in mm and as regards the heat plates in cm, because saucepans "always" sold in cm sizes.

Yesterday I was watching on Utube, my favourate "Tally Ho" [Sampson Boat] Episode 123, the rebuilding of an old English Gaff Cutter

Keel attachment bolts 1 1/4" thread diameter aluminium bronze, holes 1 1/4", actual bolts 1 15/64" to give clearance Keel weighs in at 9 tons.

Anyway why fuss about Metric vs Imperial? Just use what suits you for the job in hand.

I have never understood some peoples dedication to LBSC, he was a man of his time and his time has long gone. Whereas GHT will live for ever.

Just remember that for historical reasons, if Myford had not been around, many present modellers would not have had a suitable machine to work with. Bit different now of course.

Could still be called MEW, My Engineering Workshop a magazine for all aspects of home workshop use.

Thread: Myford Super 7 at SRS for only 395

I believe that when the bed was made from the raw casting, the bottom of the feet were surfaced and then all cutting and grinding was done referenced from there. The rear face of the rear shear was cut and again the rest of the shear widths and depths cut and ground from that setting. The bed below the headstock is at the same level as the rest of the shears.

Hope I am not teaching Grandma to **** ****

Thread: Determining/measuring sub-micron displacement
02/04/2022 12:34:19

Laser spots are a always too fuzzy for me. What is the error size when deciding where the centre actually is?

How does this compare to Joe's desire for finite small measurements?

01/04/2022 10:36:47

I am with Kiwi Bloke, many years ago I had to measure minute (and sometimes larger) deflections and used an optical "arm" some 20 feet long. Mirror illuminated by a slit source and projected onto a matt wall. Projected slit was a bit fuzzy by then but adequate for my application

I found the Genome Study work, refered to on the same link far more interesting

Thread: Tapping straight
24/03/2022 09:58:50

I have small block of steel with many holes drilled to match the range of taps I use. Simple to start the taps, a few turns to establish the initial important threads. Remove the block and continue. Most of my taps are spiral and I can tap almost without looking even down to M2.
