The top drawing is a little less inaccurate than the "1928-32" drawing but neither is really reliable. The "1928-32" drawing fails what some know as the "Orstin Test" by getting the tail wrong.
Notice the headlamp supports on the top drawing? I see it is also left hand drive.
Is it really possible to make an accurate drawing of the ash frame without working directly from an original and original parts?

I think that's why Gary Waiting's excellent offer is the best way forward.

It will be a long process to get it right, and cover each model of the body, but why not.
I am being assisted by a couple of "M-Type Body Builders", so I am confident our final drawing will be worthwhile.
Progress drawings will be posted here from time to time for comment & advice.
We are here for a good time, not a long time !. |

I didn't go to Stoneleigh so wasn't aware till opening SF this morning, of the barn find M on display.
This car looks, from the small photo, to be very original but maybe those who went know otherwise?
If indeed it is, and the owner can be persuaded, with modern 3D scanning it should presumably be possible to establish an absolutely original outer form and thus the outer faces of all timbers. Traditional measurement of those timbers should then be able to determine their other dimensions, or maybe even they could be scanned?
Perhaps I'm looking through rose coloured spectacles but from my perspective as one who knows of these techniques, but not much about them, it all looks possible.

I guess they'd be willing then? I suppose cost might well be an issue.

It is possible to scan both a car and the parts.
Angie and Andy would be OK for the car, MV 12, to be scanned at a time and date to be arranged.
There are various companies that would scan the car, but I do not know enough about 3D scanning to be able to say that it would do the job required.
Obviously it would be good to have an exact copy of the outside of the body, and then if other original bodies were scanned, they could be compared.
However, I am not sure that I am off in the "realms of fiction", but after seeing a programme on 3D printed car bodies, I wonder!

You can scan the car, this is done by taking a lot of digital(usuasly laser based) measurments.
This gives you a “point cloud” of all measured points.
Distiling this in to a usable model with sheets or solids (from which you can make sections and other parts) is a lot of work as you want a clean smooth sheet and not all the little variations that the body has (riped fabric etc)
So after a lot of time you end up with a solid or shell model the shape of an M type with all wings, wheels etc.
A nice but costly and time consuming job, if searching for these services look around in the yacht business.
It is used there for refits etc and some one might be willing to do the job for fun

Did anyone see the August 2017 issue of The Automobile? There was an article about the resurrection of the only remaining 1914 GP Delage which had suffered a crack in a combustion chamber of its fixed head engine.
They 3D scanned the block and used the resulting files to 3D print the sand moulds to cast a new block. Of course with such a car money is probably not of too much consequence, although they decided on this course as being cheaper than the alternatives.

I am offering my drawings at no cost to the MMM-Register - just saying ?.
I have no agenda here - my M-Type has (and always will have) an Australian built body.
As a retired draftsman, I just thought I could give something back.

Tony, I hope in no way you think I am seeking to denigrate your efforts; nothing could be further from the truth. I merely offered my thoughts in the hope that they may prove helpful and if in any way I have offended you please accept my heartfelt apologies.
Very best wishes,
Dave |

I have been following this thread with great interest as I suspect I will end up with an M when too old for the Fs & J! Proper drawings will be immensely helpful.
KUTGW!
Cheers

No offence taken, this is an open forum and we are all adults.
No one will ever be forced to use the drawings being discussed, and they will be clearly dated and sources noted, so there is no confusion for the next 90 years.
I also have no intention to put any current M-Type Body Builders out of a job - just capture their expertise for posterity.

| With respect to Gary's posting,in this day and age of "super" technology is there any way of just "photographing" Gary's original pieces and coming up with a detailed dimensioned drawing of the item?I hope you get my drift! - Rich |

| Some parts are really difficult to measure, with the A posts and boot lid sides probably top of the list. They were clearly machine made from a master copy and it's quite likely that original drawings never existed in the way we might expect. Most likely patterns were made which could be cast in metal and used in pantograph type machine. Although it's been said that there was some margin of error I have found pieces to be astonishingly identical and even a small discrepancy can throw everything out. Certainly a library of drawings of measured pieces would save an awful lot of trouble. |
