Thread: EN1a vs EN3 steel
06/03/2019 13:06:04

4hrs 20mins RTT, Lincolnshire is a big place

Thread: Precision division plates
06/03/2019 12:36:40

I have been thinking a lot about making division plates. Simple, make an approximate plate, bolt it onto your indexing head and use it to make a more accurate one. Thanks to the magic of the 40:1 ratio your new plate is 40 times more accurate. Repeat for evermore accurate plates.

But...

How do you make the accurate worm wheel in the indexing head? Any error in that will be directly copied to the plate you make.

Yesterday while enjoying the sunshine and watching a shadow move across the floor, I had an idea. Accurate clocks are easy to get, If you know time elapsed you can calculate how far the sun has moved across the sky.

This got me to thinking, if I had a telescopic sight, welders goggles, milling machine and a large contraption so I could mount it all on the altazimuth plane. All I would have to do is line up on the sun and cut a tooth, and repeat every N seconds.

N = 86400 / (teeth on gear)

N for 40 = 2160s = 36mins

As the gear is symmetrical you could rotate it 90, 180 and 270 degrees and cut the other teeth.

Six hours, of uninterrupted sunshine might be a little hard to get in the UK, but 6 hrs to cut an accurate gear is a win!

Could be a good holiday project. The better half roasting on the beach, you amazing the locals with a huge machine.

Thread: EN1a vs EN3 steel
06/03/2019 11:39:53

Thanks for all your replies.

I have just moved to Lincolnshire near Skegness. Not an area known for its metal working history, great for potatoes and cabbages. I have tried to find a local supplier so I can avoid the shipping costs, guess I will have to buy in bulk.

As I am setting up my new workshop I was thinking of buying in a stock of materials. My leaning is towards making tools and gadgets, any suggestions for must have's would be appreciated.

I found RapidMetals today, a model engineers sweet shop by the looks of it, shame it is a 5hr round trip. Anyone tried them?

Macc Models looks good, as they dont give a any specs for the steel I would have avoided it. I have been caught before with steel that turns to create a shark skin finish. Great for removing hard skin, not so great for a bearing shaft.

Hi,

I am reading Howard Hall's "Milling A complete course" and I am rather taken with the idea of building the tools in it.

He specifies that 230M07 (EN1a) should be used for most of the parts. I have been looking for suppliers of it and it seems to be rather rare. In particular the 50mm x 50mm  square seems to be not available. Most steel I can find is 070M20 (EN3) or just called "mild".

Would EN3 turn and mill OK?

I don't expect to get show condition finishes, but would the finish be OK?

Any suggestions on small quantity suppliers who ship at reasonable rates?

Thread: AutoCAD substitute
04/03/2019 18:05:57

I dont know much about CAD software, so cant recommend one, but do you know about open source software? It is free to use and is written by users for users. Note this is different to free ware, that usually comes full of adverts or malicious code.

If you google for "open source alternative to autocad" you will find quite a few that you can then look at the features to decide what you like the best.

I think I have found a new hobby, searching ebay for a "hand metal shaper" It is very distracting.

Thread: Low rate automatic house plant watering system
02/03/2019 12:38:38

Assuming you have some pressure available on the RO outlet, my crack pot design would be;

Mount an auto flushing urinal cistern several meters up, not a fancy electric one, just the old fashioned fills and flushes one. Fill it with the RO output.

Construct a small water turbine, attached to a bell, and connect to the flush output.

Below this mount a header tank that receives the flush.

From the header tank run normal drip irrigation.

As a cistern is about 5L capacity you will get a flush per day which should keep the plants happy.

The bell will give you that warm fuzzy feeling day or night that it is all working and your plants are getting watered.

A low tech alternative and politically correct green, would be to replace the cistern with one of those bamboo water features. The ones that fill a length of bamboo and when full tips over and empties. That could then empty into another length of bamboo which replaces the header tank. With a bit of ingenuity you could replace the drip feed with smaller diameter bamboo and reeds. You still get the audible operation indicator from the donk thump of the bamboo tipping.

Thread: CBN Wheels
25/02/2019 21:15:11

Hi I am considering buying a CBN wheel to use for sharpening lathe and mill tools.

Axminster sell a large wheel that is electroplated with CBN. All the T&C grinders I can see in back issues of MEW use cup wheels.

When I search for CBN cup wheels I seem to just turn up ones that are resin bonded.

Questions are;

Could I use an 8" wheel to sharpen mill tools or do I need a cup wheel?

Does any one know about the life time of resin vs electroplated CBN wheels?

Thread: Workshop - indoors or outdoors

I would go cellar, artificial light is not a problem, if you are like me you need to have extra lighting on your work any way.

Work out how to build a ramp for the coal hole, add a good chain winch and getting things in and out would be easy.

Also I am half way building my garden workshop, it is quite a long job, and costs many £££. If i had a ready made space I would have used it.

Hi Gordon,

The building regs now have a chunk all about sound proofing so materials are quite easy to get. Have a look at https://www.insulationexpress.co.uk/guides/acoustic-insulation/how-to-soundproof-a-floor or https://www.soundproofingstore.co.uk/timber-joisted-floors for a starting point.

Shop around for financial advise, 3% is high, I am paying 0.5% to the adviser and 0.4% to the investment plan.

Re estimating your longevity, look at your parents and relatives.

My plan after my wife dies is to buy a barrel of single malt whisky, and pop speed. I will have plenty of energy till I burn out.

Thread: Chester Craftsman Lathe
03/02/2019 12:46:04

Hi Alan,

This link is for another Operators manual which seems to be the same as the Craftsman. **LINK**

I have spot checked the parts list with the Craftsman and the part numbers seem to be the same. Thing that puzzles me with the Grizzly g9249 and the BT1337G1 is that they say 37" (940mm) between centres where as the craftsman is 23" (570mm) . This is despite the bed part number being the same in all three parts lists

Chester could sure do with rewriting the manual, it is terrible.

Thanks Howard,

I actually have that copy of MEW thanks to my wife buying me a whole load of back issues for Christmas.

Hi Martin,

Yes I would be interested, but I am at a loss how to shift it. I guess your relative got it in, so he must know how to get it out. I am a few months away from having the workshop ready though.

Yeup, sounds sensible, a local engineering group would be great. So far I have not been able to find one.

Thread: Milling on the Chester Craftsman
31/01/2019 17:29:00

I have looked at the Boxford and liked them, a little puzzled what all the AUD, BUD, CUD mean. I stopped looking as they stopped producing them in the 70's, and the current manual lathes start at 3 x my whole budget.

I dont have anything against buying second hand, except I don't feel I have the experience to tell if it is a gem or a lemon. Plus the whole shifting it out of someones workshop would add to the cost. New would be delivered and at least dropped on my drive. I can put it in the garage and then take my time moving it into the work shop.

I am not overly hung up about getting a gear box, i quite like setting up the gears. I am pretty sure the Craftsman has a 127t but I will put it in my list of questions for them.

I have just had a reply from Chester regarding the T slot and fitting my vertical slide. They offered to fit their vertical slide FOC, If i buy it of course. I assume they must drill and tap the cross slide as the one shown on the site has 4 mounting holes.

Thread: Hi from East Lincolnshire

Hi All

I have just retired and moved into the area. I am in the process of building a new workshop approx 4m x 3.5m which is brick skin with insulation and inner surface of ply. I hope this will be a good and dry.

I do not have much experience with lathes etc. School boy access to a lathe, then about 10 years ago was given a 1912 Drummond B. My father was helping clean out an old boys garage and found it between the fence and garage where, it had been regularly soaked in old engine oil so not much rust. I started to restore it, lots of bed scraping got the slide moving over 3/4 of the bed. Also repaired cross slide thread. However the big blocker for me was the worn bed feed screw and nut. At some point it had been repaired with white metal being pored into the thread. Works fine for 1/2 the travel, Solidly jams after that.

I have recently inherited my fathers Myford ML1, not in great condition, not too worn but the chuck end bearing pinch clamp broke off, and has been replaced with a hand made cap.

I have always wanted a Super 7, but the price is beyond my budget. So I have decided on a new lathe that meets or beats the Super 7 spec. The short list is; Warco WM 250V, Chester DB10 Super possibly long bed, Chester DB11GVS or Chester Craftsman.

I have always wanted a mill too, but recent price rises have made that unlikely to be in my budget. I already have a Myford style vertical swivel slide that I used on my Drummond. This on the Craftsman I think would do me perfectly. But I am not sure if it can be fitted without a lot of modification. Possibly making a new cross slide, which would be difficult with out a mill. Good old chicken and egg!

An alternative is to go smaller on the lathe and buy a mill, possibly even down to the WM240B.

My other consideration is metric and/or imperial, I am of an age where I work in both, but have inherited a lot of imperial tooling. The Drummond spoilt me with a 127 tooth change wheel. So metric threads, no problem.

These new lathes seem to not have the 127t and only offer approximations, and I don't know if this is an issue for me.

I think my interests lie mostly in tool making. Dreams of making index heads, hobbing tools etc. I do have an interest in sterling engines and do wish to make some too.

So enough of my ramble, time to get back to building the workshop

Thread: Milling on the Chester Craftsman

Yes I saw that, but the images only show a large T slot in the topslide.

30/01/2019 17:30:31

Hi,

I am looking at the Chester Craftsman, but If I get the Craftsman, I wont have the funds to buy a mill.

From what I have sen it does not have any T slots on the cross slide so I cant see any way to attach my vertical slide (Myford swivel type)

Has any one used the Craftsman for milling?

Thanks

Adrian

Thread: Hi all from Lincs.

Hello All,

Well this is a fortuitous post. I just signed up with the forum to see if there was anyone near me and to introduce my self.

I have just retired and moved to East Lindsey and I am just starting to build my long dreamed of workshop.

My experience is not much more than a handy man with fond memories of the Super 7 at school. I do have a very tired 1912 Drummond flatbed that I started to restore, but that may be a little too far gone.
