Thread: Choice of small milling machine
13/03/2010 20:47:58
Robin
I ordered the new Warco WM-14 just before the Sandown show on the advice of the Warco Technical dept.
 
They said at that time that the machines were due to arrive in the UK in January. In the event, the machines arrived in the UK in late Feb and they were then each checked out at Warco.
 
My machine arrived with me about two weeks ago having been resealed in the packing case and loaded onto a small pallet. Although I was promised a phone call to say when it would come, I didn't get one and it was just fortunate someone was at home!
 
Unfortunately apart from opening the packing case and checking the contents, I have not yet had time to install it & try it. It came with an individual accuracy report, operators manual, toolbox and tools etc and looks ready to use after cleaning all rust protected surfaces(heavy thick grease)
 
Hope that helps

Hi Robin
If you call Warco & speak to Roger (?) in the technical dept I think you will find that the WM14 which they are selling from January is an upgraded model and not at all to be confused with the model they had at the show or the model reviewed in one of the postings above.
I believe you will find it has a larger table & now comes with a digital rev counter & head elevation the same as the WM16 in fact it is now very similar to the WM16 and much superior to the Mini Mill.
Yep, I ordered one too after speaking to Roger
Cheers

have you looked in yellow pages for steel stockists?
I found one near me in Norwich and he is waaay cheaper. He'll cut off short ends as well.

 Hi Roy
 
 That's the Grinding Rest I was thinking about!
 
I live in Suffolk so I'm interested to know which stockist in Norwich that you mean.
 
Cheers
Ray

I've been looking at a couple of Harold Hall's books in the Workshop Practice Series with the intention of building a Grinding rest for Tool & Cutter sharpening. He specifies using 070M20 steel in one book & 230M07 in another book both in metric dimensions. I've looked up these steels and think I understand the principle difference is in their milling capability.
 
I then look in the magazines (ME, MEW) for material suppliers and those ads & websites I've noticed specify for example - BMS (British/Black/Bright? Mild Steel?) in flats, rounds hexagons etc all in Imperial or for example
Precision Ground Flatstock (in metric) or for example
Black Mild Steel or for example
Bright Mild Steel or for example Silver Steel
but certainly no mention of the 070M20 or the 230M07!
Just realised that 230M07 is also known as EN1A & that 070M20 is also known as EN3B but is this convention used?
So, which metal suppliers do you all use or recommend?
 
Do you bother whether it is070M20 or 230M07 or BMS or whatever?
 
Help Please
Regards
Ray

Thread: Milling Tools
27/11/2009 20:33:38
OK Guys thanks for all your replies and I get the message!
 
1. As per "Milling A Complete Course No 35" (which I have) I will be making my own T nuts, clamps & parallel bars
 
2. I will also collect some old ball races as supplementary parallels and look out for some structural steel angles to make my own angle plates
 
3. I will only buy milling cutters as I need them (only 1 or 2 anyway) and they will be of quality European/N American manufacture
 
4. I will only get the odd taps & dies, again as I need them and be of best quality only
 
5. I will buy a dial indicator & stand, an engineers square, a set of drills and a Wobbler or two
 
6. From Hemingway I will buy a couple of G H Thomas kits next year eg. The Small Precision Boring Head & The Versalile Dividing Head
 
As Circlip remarked above, this way I will save some money, gain some experience and get a sense of achievement.
 
One question, any recomendations for UK suppliers of "quality" tapd, dies, drills etc?
 
Thanks everybody
Regards
Ray

Expecting WW3 Ray?? If you're going to a training establishment I can see quite a few bits on your list that you could make. You would also gain both machining experience and a sense of acheivement??
 
  Regards  Ian.
 Hi Ian
Firstly thanks to all who have replied.
I think the idea of old ball races for parallels is a great idea and I will go that route initially then maybe see if I can machine/grind some at the college.
Re the Angle plates I have looked at buying castings and machining them but as far as I can see it works out more expensive, so does anyone know of a supplier of cheap angle plate castings?
Clamp sets, yes I can collect/make my own. Who are J&L by the way?
Re WW3 Ian, no it's not imminent and that's why I asked if what I was considering was "overkill" but I think you're right, I'll just buy in dribs & drabs ie. what I need for each project I start.
The thing is I'm going to the Sandown Exhibition  and I wanted to identify any things which I need and which may(?) be on special offer there.
 
Cheers

I have recently got a Myford Super 7 & I have ordered a small mill (from Warco). I'm not sure what tools to buy at the same time but I'm currently also attending an adult education weekly course at the local college - Engineering Workshop Practice which is great.
 
Anyway I am considering getting the following for use in/on the mill:-
- a set of ER25 collet & chuck set
- a set of end mills
- a set of slot mills
- a milling vice
- a clamping kit
- an angle plate
- a set of parallels
- a boring head & boring bars
- slitting saw arbor & 2 or 3 slitting saws
- a tap & die set (metric)
- some drills including drills for the taps above
- a wobbler set
 
Have I forgotten anything, is it overkill? I was thinking of getting most of these bits from Chronos or Warko but is there any advice please?
Cheers

Thread: Which Cutter Grinder?
19/11/2009 21:50:26

I wouldn't have described Harold Hall's jigs as jigs. Indeed Hall himself describes them as Grinding Rests for use with a D/E grinder. They do include adaptors to enable the sharpening of milling cutters.

It all depends what you want to do. If you want a kit of parts, then you will have to buy, eg the Worden, but if you wish to make from stock materials, then Hall is the way to go.(And possibly cheaper as well.) Workshop Practice Books 35 (Milling A Complete Course), 38 (Tool and Cutter Sharpening) and 39 (Model Engineer's Workshop Projects) refer.

 Hi Peter
I already have a copy of #35 and have had a quick look at the grinding rest and the associated accessories HH describes. I dont yet have #'s38 & 39 (on order now) but does he describe other cutting/grinding projects or are they the same as those in 35?
regards

More than anything else, it depends what you want to grind?
 
And what you want to make it on?
 
If you want to grind basic lathe tools, sharpen drills and do endmills, then the standard kits are fine - indeed perfect. Harold Hall, Worden Kennet.
 
If you want to start grinding tapers for reamers for injectors, or taps, taps for specials, cams for IC engines etc then you have to go for a Quorn or a Stent.
 
The Quorn you can build on a Myford if you have a vertical slide - the Stent I don't know.  
 
 
I presume you have a dividing head that will do 360 divisions - or can get access to one.

 OK, good question Meyrick.
Yes, at this stage I want to be able to successfully grind lathe tools, drills & milling cutters. Regarding reamers , taps & grinding cams I don't think so but maybe in the future ....?
So, that sounds as though its either Harold Halls's jigs or the Worden or Kennet.

Hi There
For lathe tools, one of Harold's jigs would do fine.
For end mills and slot drills, I would buy a few from Ebay and use them till they are worn and then buy a few more.
You can buy an awful lot of tools for the cost of a set of cutter grinder castings and you can get someone at your local club to sharpen them for you or sell them on Ebay and buy some more.
I used to collect all the old cutters from work that they could not be bothered to sharpen and they all sold well on Ebay.
 
regards David
 
 Thanks for the suggestions David but maybe I should have said that part of the exercise could be the fun of building something too, hence my interest in the cutter grinder kits. I also forgot to mention the Wordon (?).

i have recently bought an old Myford Super 7 lathe and as a beginner I am attending a weekly engineering workshop course at the local college where we have access to lathes, mills etc. as well as a very experienced engineer to guide us through our projects.
 
It has rapidly become apparent that to get the best from the equipment the cutting tools have to be in excellent condition and sharp - something they are often not after use by the full time students!
 
So, what advice do you have re a cutter grinder for my home workshop to either purchase or build? So far I have found the Stent, Kennet & Quorn to buy castings/parts & build, the Clarkson to buy secondhand (Ebay) or I believe there is a simple jig to make in Harold Hall's book "Tool & Cutter Sharpening".
 
Any comments appreciated.
