|Thread: Compressed air on lathe|
Need to be careful with a vac David, spray swarf like Brass is ideal for letting the magic smoke out of electrics.
You COULD always try this :- http://www.cgallery.com/jpthien/cy.htm
Oh Bu**er, sumat else to make.
OOOPS, forgot the baby version :- here

Some of the "Re-invented" technology uses a combination of compressed air and atomised cutting fluid fed to the cutter/workpiece interface for "Mist" spray cooling.
Thought to be the best thing since sliced by some, "Duplex" did an article on it in 1957. Sadly only have pages 1,2 and 5 of it. (Hint David and s*d the subscription

By ell Peter lad, tha deserves Yorkshires highest award, FC and Bar, (Frugality Cross).
As tha tried resharpenin t files by pickling em?? Aye, an keep thi powder dry, dowant tell em abart usint files fo cutters, fytin thi way tert front on car buwit sales is bad enuff bart damn kids gerrin under foot.
They mek damn good wood chisels anorl. Brok one of me Grandads that i left me, by ell, a did weep, saved bits tho.
Keep upt good work lad, best wishes fromt reyt side oft Pennines.
|Thread: "Precision" or "does NOT do what it says on the tin"|
As you state Chris, the supplier should be allowed to advise before you witter. So why Didn't you go down that road first?????
One of the sad results of many who have disposable income to burn is that basic skills suffer due to the ability to throw cash at a problem and expect to become master craftsmen.
The collet system was introduced to allow the fast turnround of material to make vast profits for the engineering company owners. As you have stated in the past Chris, you are part of the human RACE, so your free time to partake in an alleged HOBBY must be somewhat of a dissapointment to have to set up a four jaw.
Did you pay a lot of money for the mentioned set??, The ones from Crawford and the likes never seemed to suffer from these problems, or are we talking Chiwanese???
It REALLY surprises me how the likes of Thomas and Westbury et al managed to produce items that FAR exceed in quality and finish, some of the renditions made with the ADVANTAGES?? of all the latest "Home workshop" technology.
|Thread: Opus Proximum|
IIRC Op. Prox. was one of a series of engines that had dual dimensions to appease the growing grumbles from the ranks of the "Why no metric designs"???
Sadly, unless the design gives the EXACT numerical equivalent from WHICHEVER system is used, approximations introduce errors rapidly. 25mm is NOT 1" and neither is 1/2" 12 or 13mm.
I wouldn't be surprised that if you worked the parts in imperial it fits and works??
Years ago, the D/O I worked in used to have to go into the works to "Sort out" percieved Drawing errors. When you have to start at one end of a machine and check out why a bracket on an assembly 30Ft away doesn't line up, it doesn't take many "proud sixteenths" or "Shy eighths" to loose OR gain inches at the other end.
When the workings of a mechanism are UNDERSTOOD it doesn't matter which system is used providing you design the bits using the appropriate sized materials FOR THAT SYSTEM. Sadly, cos some of the CAD programmes mean that most can now draw straight lines and lines that intersect at right or whatever angle can be specified, it DOESN'T mean that they are DESIGNERS.
To Illustrate, 1" - 1/8" twice = 3/4" OR 25.4 minus 3.2 Twice = 19, BUT 3/4" = 19.08. In the case of using 25mm wide material, a subtraction of 3mm per side for something like column centres matters not a s*d, but 25.4 minus 3 twice, although in the example given doesn't matter for column centres but can be disaster for valve or pitch settings.
Unfortunately quite a few of Stans designs have been critisized by whingers (Present company excepted) and copyers who try to change things without understanding the implications.
A colleague is at presant making an engine originally designed in imperial. Luckyly he has someone to help with the IMPORTANT sizes to maintain and the "Floaters", providing a few down the line are taken into account, CAN be solid Metric.
|Thread: Overheating grinder|
We are constantly being told that "Modern" motors run a lot hotter that propper ones Peter, as long as it's not singing a tune (As in the windings rattling) you should be OK.
You should save all your sharpening and grinding jobs till this time of the year as it helps to keep the workshop warm.
|Thread: DIN tooling|
The German "DIN" standards are more or less like the old British Standards Dunc. One company we used to deal with "Berang" had a catalogue of items they supplied with the various parts shown manufactured to the specified DIN standard with dimensions shown for the range of parts EG. Tee nut Dims. and another for Domed head nuts all in metric.
Like BS. lots of the DINs have been replaced with ISO numbers.
|Thread: where can i buy a bell punch?|
Trouble is Dave keeping the little sods square with the end of the barstock. if you've faced the end, hit it with a centre drill, otherwise, tother Ian has given the answers.
If you really MUST have one, not too difficult to turn a 70deg female cone, drill and ream centre for a standard Dia piece of Silver Steel(Drill Rod) and cone and harden a piece for a centre punch.
Who knows, if the Chiwanese see it, they will be in the shops in their millions.

|Thread: Old Model Engnieer Magazines on CD/DVD???|
So, about 25 issues per 4.7 Googly bites, even WITHOUT indexes, indesneeze - a contents listing, 6 DVD's take a lot less space than 1350mm (4ft 6ins.) of heavy paper.
John Stevenson recently got rid of virtually a complete set of M/E's and you could see the shelf groaning under the weight of the "Terrace of back to backs"
I suppose that if the mags WERE put on DVD's by the management, this would stuff up the "Carrot" of freeview by "Subscribers only"???
The emergence of DVD's has made bulk storage a much more viable proposition (Remember 3 1/2" floppies??) so the only way to "Store" them is to get enough like minded people to "Do it themselves" ONLY for each others benefit and NOT for monetary gain.
A private individual group has been offered to the management to take on the task for one of the magazines mentioned as it IS a time consuming job, but if shared out, -- Many hands etc.
|Thread: Clarke milling attachment|
To answer the question you arsked Dave, it IS a space saving exercise and DESPITE what many say, yer pays YOUR money and takes yer choice. My Lathe has a milling attachment fastened to it and is the ORIGINAL that all the far Easterns have copied.
An before the screamers get in amongst, it does everything I WANT IT TO DO. Can direct you to many sites where the machine that gets lots of derision from all the experts, namely the "Combi" machine with the mill/drill head on the headstock, has been used to create far better pieces than some with all the latest gizmoes.
And don't forget, size ISN'T everything.
|Thread: Broken Tap Extractor|
And acid will strip the Zinc out of brass.
CAREFULL ChrisS, the FW's are beckoning.

|Thread: Question on bolts|
D I wasn't thought to be a problem then Tim, so why worry now?? Mainly a case of get what you can. If you have a look at some of the adverts in the ME at the time the original articals were published, the suppliers don't make a big thing about it.
And don't forget, Brown paper makes excellent gaskets and a darn site cheaper than PTFE foils.
|Thread: Broken Tap Extractor|
If it's a CARBON steel one, a saturated solution of ALUM, (Look it up), but if HSS there are one or two circuits for simple spark erroders, although the "Experts" will probably advocate using a carbide drill.
|Thread: Question on bolts|
Don't forget there's a gasket between the faces Tim. Stainless RESISTS rusting (Covering all bases) but if an LBSC design, the original would have been Steel, the stainless's were in less supply to the "Toy" fraternity.
|Thread: Rear mounting parting-off tools|
One of Mark Twains' I think,
"It is better for people to think one is a fool than open ones mouth an dispell ALL doubt".
|Thread: Logging on Problems|
Getting REALLY vexing having to keep logging on longhand, and this is the only site it happens on.
|Thread: Model Mechanics magazines|
Thanks Richmond, what a dastardly trick, putting 4 issues free and then subscribers only. Tut Tut Tut.
|Thread: Mini Lathe and Milling Machines|
Tell me where you are John and we'll stretch a piece of string between us, cos that's the answer to the question you've just arsked.
On a more serious note, and I have been known to do this at times, you need to write down what your objectives are and be honest with yourself of your perceived abilities. I could give you a list of lathes and milling machines to look at and the next guy will tell you "Don't consider those". The old addage Horses for courses should be used and DON'T fall into the "You can turn small stuff on a big lathe but not big stuff on a small one" trap, if you're turning watch parts you DON'T need a Myford (Although, my mentors used to do that on one).
Have a look round at what you think you would like and show a comparative list and wait for the opinions to fall, they surely will, like a snowstorm. Then it's down to your wallet/plastic.
