Scaleing Plans

<< < (2/2)

Sackett:
I've picked up a few bits,,, scale as Toolshed showed, some triangles ,,n some hard penciles, n t square. My plan is to print two sets of plans. White out dimensions on one, then take the original dimension off other, upscale it, n transfer to whited drawing, which will become new working plan. Is this a viable plan,, or is this likely to go horribly wrong

Pete W.:
Hi there, Sackett,

Your proposed plan sounds good to me.

My late wife worked as a tracer in an engineering drawing office and later as an instructress in the use of plastic drafting film and she taught me some of the techniques.  In those 'old days' of 'blueprints' and diazo printing, you could get drafting film with a diazo sensitive coating on the back and a pencil or ink coating on the front.  (The raw polyester sheet wouldn't take ink or pencil very well - so sheets were available with various types of coating.)
One method of producing a variant drawing was to take copy of the original drawing on that type of film.  Then you got busy with your scalpel or razor blade and scraped off the unwanted parts of the drawing from the back of the sheet.  Then you drew the required new details on the front of the sheet, marrying up with the parts of the drawing that didn't need to change (using pencil or ink according to local practice).

What you're proposing is essentially the same procedure but adapted to hobbyist scale use of ink-jet or bubble-jet produced prints.  I suggest you use pencil until you've checked your scaled dimensions.
If you find a way of liquefying aged Tippex please report back here!   :lol:   :lol:   :lol: 

Toolshed:
Your method of DimensionX times 2 should work fine.  Can we get a picture of what you're scaling? 

A double check of your scaling should be done to check all your dimensions by REDRAWING the piece at the new dimensions.  That 'should' eliminate errors if they exist.

NormanV:
It all depends on what you plan to make. If you are building a model (engine, car, boat, aeroplane etc.) It will look very chunky as the bolt sizes and material thicknesses will be out of proportion.

Sackett:
What I have in mind is some of Elmers engines, specificaly the #3 mill engine , and the mine engine. If all,or "most" goes well,I'de like to build a complete set of Elmer's, as drawn, n 2x. A long range plan,, but a plan none the less.
