Thread: Worn Myford quick change gearbox lead screw bushes
05/07/2018 10:01:09

F Y I, The Myford QC gearbox categorically did NOT have bushes fitted to the bores where the Leadscrew runs. Any that do are third party, post production modifications to account for wear. All Myford boxes had the steel Leadscrew running in the cast iron of the box at BOTH ends. Malcolm was stating fact.

Finished projects? No, never, ever finish anything before you start something else. That way you'll never be stuck for something to do. It works fine for me anyway.

I concur with the statement made by Mark Rand, , , I missed this posting. But, I'm in the Midlands and I'm with the 'Yes' faction.

Thread: Myford super 7
16/05/2018 17:50:53

ahh, Robbo, it's THAT one! dug out my old S7 manual earlier and realised it must be. Picture here is worth more than a thousand words Hoping it helps sort the problem for MIchael. One thing I would add is that one of these I worked on was dragging due to a really stiff ball race in the pulley. Full of accumulated muck.

Michael, the clutch on your super 7 is the front brake drum arrangement from a moped. two of the ML7's in my shop are fitted with the same unit, but in the countershaft primary drive pulley. Do NOT oil the shoes, after all, you wouldn't put oil on it if it were in it's normal position being used as a brake. First of all we need a little more clarification as to the problem. Is it clutch DRAG? which is slipping caused when the clutch is disengaged but not clear enough from the driven side, or is it clutch SLIP?, which is slippage caused by not enough engagement pressure when the clutch is engaged to drive.

Thread: Is this normal in backing plates

In agreement with a post made recently, I'm sure John Stevenson would advise the OP to take up knitting. In the past I've advised people who seem to be pretty clueless to take up baking or gardening, only to be berated for it and to receive PM's stating ' it's only a hobby lol' . Puts me in mind of the kind of giggling childish adults posting Darwinian crass stupidity on YouTube, due to them having little knowledge or understanding of much at all.

Be safe and don't kill yourselves with things you know precious little about, otherwise the H&S Gestapo will be down on us all. Pressure vessel testing for club run equipment I fully agree with. Telling me that I can no longer run my surface grinder, bandsaw, t&c grinders, millers, lathes and drilling machines at home because we have potential clients for the idiocracy in our midst I certainly don't want.

L O L .!

Thread: Doncaster show
12/05/2018 18:28:09

Went on Friday. Main car park full so found room in overspill park. Arrived about 11.00 and walked straight in to get a ticket, no queue and off round the stands. Quite busy and some outstanding work on display. Some of the trade stands gave the impression of being half the size of previous years and I don't know if Warco attended but I didn't see them. Managed to buy what I needed with very little jostling of shoulders and backpacks and noted various suppliers contact details for future purchases.. Went to the upstairs display of aircraft and gas turbines and the food and coffee smelled delightful. Back in the workshop now sizing several sets of ML7 half nuts wot I have cast, with a nice new 8tpi Acme form LH tap from good old Tracy Tools.

Thread: Screw Cutting

The numbers refer to the teeth carried by each gear in the train. The last gear (75t) is the one which you fit on the leadscew.
Thread: Myford gearbox question
06/05/2018 00:18:00

Yes it's fine to have the gearbox running whilst selecting ratios A, B and C. This ensures the drive dogs engage correctly. It's also ok to engage the selector whilst using fine feeds but, not advisable to engage the selector whilst in the high (screwcutting pitch) range as the gears may be subject to wear or damage. Better to rotate manually to engage the selected pitch. Glad you got the problem sorted.

05/05/2018 17:54:18

Are you sure the drive dogs are engaging correctly when you select positions A and C with the top selector lever?

Thread: ML7
22/04/2018 17:59:50

It isn't a pair of nuts. It's a pair of thrust blocks, one fits either side of the clutch actuating lever pivot.

Thread: Myford ML7 Manual Instructions
07/03/2018 21:41:28

Andrew, the photo, fig 35 on page 25 has no connection with the 3 diagrams in fig 36, page 26 other than to indicate what each part is according to the numbers in brackets below the photo fig 35 at the bottom of page 25.

The first diagram 1. on fig 36, page 26 is a simple gear train and should be read in connection with the screw cutting set up charts, figs 37 and 38 on page 27.

basically 1 in fig 36 shows 2 as the driver, 7 as an idler, 1 is simply a spacer gear to fill the empty space on the stud and 4 is the driven or leadscrew gear. If you read the diagrams 2 and 3 in fig 36 in conjunction with the charts it's all pretty self explanatory. The numbers 1,2 and 3 in the diagram boxes refer to the end column marked "set up". The circled numbers show the relative gears and positions taken up on the studs to provide simple or compound reduction train set ups, hence the side views of the banjo indicating with dotted lines the gears 'behind' gears. You'll notice that certain trains require the leadscrew gear to be on the inboard or outboard end of the leadscrew depending on the train type requirements. Simply move the spacer from one side of the leadscrew gear to the other.

Thread: Do I have too many ideas and interests?
05/03/2018 08:43:32

This is basically describing me for the whole of my life. It's never done me any harm and not once for as long as I've drawn my breath have I ever been bored. . . . Carry on doing it your way. It works out fine.

Thread: Brass or Bronze for a leadscrew nut?

Very nice, , , , but what type or grade of Bronze? ? ? . . . . Ohh look, it's Tin Hat and coat on time. . .

Take up Baking ? Or gardening, , perchance?

NO ! see ten thousand other threads on here on this subject. EVERYTHING is explained painfully, in depth on every one of those threads.

Thread: Cat Litter Recommendation
21/01/2018 11:23:21

ALL clay based cat litters are Bentonite, which is a colloidal Kaolin. The stuff from casting material or craft pottery suppliers is the powdered version. The cat litter is nothing more than granulated Bentonite which needs milling to reduce the granular size. I use the cheapo Tesco stuff in the green bags. I soak it in water and mix it up to a slurry and then put it through a 60 mesh sieve. I then blend the slurry into the dry sand, but my sand is always prepared well in advance. If you want instant results buy the powdered stuff. Try Castree Kilns in Wales, but not John Winter as Winters prices are somewhat ridiculous in my opinion. Myford Boy also reccomends a foundry supply place in his videos but I don't recall the name.
