" Jason typifies the modern way. At his levels of productivity there is no time to spend on handwork when reading the dials or DRO will do "

Whoa there tiger, thought Muddle Ingineering was a HOBBY. Was taught how to use a Tally rond and a Tally surf but how many M/Es have them in the workshop? Or actually NEED them. "Orses for corses" or cut your cloth etc.. Disposable income has certainly altered the skyline.

Not many people now have heard the terms "A shy 64th or a proud 16th.

Naughty Lightening, recently had a blown ASDL filter AND BT telephone base unit K*******d by an "Instantaneous" local flash/bang.

Sam, stop worrying about super ( or not) accuracy. Before Carbides, Dro;s etc. measuring tools were a rule, tape and callipers so how did they (In Industry) manage to make anything work????? They made the parts required that fit together fit together, it was a black art called FITTING. Those that whinge for tolerances on drawings have no understanding of the concept of the MODEL they are trying to emulate. If you're making parts for the Swiss watch industry when interchangability is paramount, then the must have (By some) Mifford is a dogs body for turning parts ALTHOUGH I was taught, no, SHOWN how to turn a balance staff on a Super Seven, but this was a one off and not a multiple order from Rolex or Tissot.

Give a lump of metal and a Micrometer to five "Ingineers" and you'll probably get five different readings as everyone has a different "Feel". Note I said a Mic and not the instrument of the devil, the digital calliper or even the ones with scratched lines and numbers on them, er yes,, a Vernier clopolipper.

Enjoy what you build and make the bits FIT TOGETHER.

" problem is with the old issues that were not done at the time and even when they were scanned in during DC1's time the resolution of scanners at the time was not what it is now."

Resolution at that time was 300-400 dpi. Problem was, although offered for free by the late SJ, the company that scanned them made a right pigs ear of it.

I would never criticize use of Aluminium, it "Looks" as if you've used 6082?. Only improvement I would suggest is to anodize the bits to save the prospect of any oxidation, and yes, although other grades of alloy are better, 6082 DOES anodize.

Another couple of "Expurt" criticisms. The use of Plywood in the construction of the impeller on the first home constructed working model gas turbine. - Read the calcs, it DOES work. And a real gem, the use of reclaimed tinplate (print side in) on the painted cleading of a model steam loco. LBSC did have words to the judges on that one.

Regards Ian.

Was trying to remember John Rudd's name. He's the man.

Regards Ian.

"Is there one, Ian? What did it hit?"

Yep, straight out of boiler rebuild, first passenger trip and BOING! As the late S/J would have said "C-B". As it's of a "Size", separate drives to paddles using a couple of reversible crash gearboxes coupled to Taycol would work. Simply made to a "Beek" design.

Regards Ian.

Have you put a dent in the bows for authenticity?

Regards Ian.

Punching holes in existing "H & T" strip works.

Hope you haven't used what looks like Aluminium for most parts Graham? At one of the ME exhibitions the "Purists downgraded the "Commutator skimming Lathe for model car motors" entered by a Youf because he hadn't used the "Correct" material in its construction. ie Aluminium instead of Cast Iron.

If yours is "Incorrect", S*d the judges, it looks fantastic.

Regards Ian.

Edit, - Next years "JS" award????

Nother edit, It would have cost a lot of money to buy the "Correct" machine to spin rivet the ball bearing operation in industry.

Does "Coke" (drink) still contain Phosphoric acid? Seem to remember it being used to clean Aluminininium castings.

Regards Ian.

Tinned "Engineers Blue" - a little goes - - - - - all over the b****y workshop, as many will attest.

"Two enormous engines and no room for fuel in the wings."

So where's the fuel tanks on Anakins' pod racer???

Regards Ian.

Try Tracy, good selection.

Regards Ian.

And note, use "Oilites" guide for hole diameter in casting. When fitting they rely on a compression fit which also squeezes Oilite bore down to nominal size.

You have a PM Paul.

Take heed what Roy said, the platform escapement, (The bit that the Balance assembly is fastened to), is a magnet for careless handling. Doesn't take much to slip with a screwdriver and break the balance pivots.

Regards Ian.

Carbides and superglue are not the answer to everything. Hailstorm will start. STOP using carbides on baby lathes. Test IS 60W blub for control board. Worst case scenario, motor AND control board, going on £300 - £400 to replace. Use HSS and lighter cuts.

Regards Ian.

Piano wire supplied in model shops was in 36" (914.4mm) lengths. This was before T'nternet and instant gratification (Pre Covid) killed most of them off.

Regards Ian.

PS. Bunging a few amps (Low Voltage) through a wire held in tension will "Set" it straight. Have been using Pirrana wire in a string tensioned frame for hot wire cutting Aero wings for years.
