Workshop Weekend
 
Last weekend I went to a workshop weekend hosted by Duncan Grimmond. Duncan is a professional sheet metal artisan (http://www.zinccounters.co.uk/) and also a fellow Pembleton enthusiast. Once or twice a year he is kind enough to open up his workshop so that Pembleton builders can access his huge range of metal forming tools - folders, shrinkers, stretchers..... The main job I wanted to do was to form the flange on the floor which is curved and so potentially tricky. Duncan made it look easy....

While we were there I managed to get a few shots of Duncan's second Pembleton which is currently under construction.

A standard to aim for! A few more pictures on my Flikr pages.

And its in....
 
Engine fitted at last. Everything went according to plan (well more or less). So I know have an Italian engine mated to a French gearbox using a British adapter. Cool.

A few pictures...

Completed engine from the front. The original ignition was fired from a pickup on the Guzzi flywheel. But of course I am now using the 2CV flywheel. Proiblem solved by using an old school analog electronic igntion from Lucas. The pickup goes on the end of the camshaft.

Next step - to get it started - but still a way to go yet....

I have been working towards getting the engine running. Lots of little jobs to do first.

New bracket for clutch cable. The original one that was welded to the chassis meant the clutch cable was poorly aligned and right at the end of the adjustment.

Carbs trial fitted with air filter from Ebay. Not the best of solutions but it will do to start. Neck for air filter clears chassis by at least 1mm!

Old school electronic ignition (Lucas Rita) with coils underneath. The Guzzi employs a lost spark system which means two coils.

Looking good Robin! :)

I'll have to let you borrow my polishing mobs to keep the engine and body work (you are polishing all that loverly hand formed aluminium, aren't you?) spick and span. ;)

woodsmith 11th March 2013 16:42

That looks a lovely build!

I found a 2CV chassis already converted as a trike on Ebay a few weeks ago. I was really tempted with it as a basis for my current project but I am building a reverse trike load carrier and I doubt the 2CV brakes and suspension would be up to the weight I am expecting.

I should make one of those beading rollers at some point and fold some metal.

Are you volunteering? ;-).

Long way to go before that stage. Tally ho!

Small update on the carb mounting. When I tried to fit the nearside carb it still fouled the chassis - doh.
So I bit the bullet and modified the inlet stubs adding a new bit made from 1 3/8" ally tube which just happens to be a good match. (No it's not my welding....)

Now everything fits!

The only downsoide is that I used about 50mm of the ally tube - but I had to buy 2500mm! Perhaps I'll go into production...

I really like the engine :D

I spent the last few weeks making a metal folder. It had to be done without welding (as I can't) and cheaply. Here is the result

I only need to make half a dozen folds or so but didn't fancy the suggested blocks of timber approach. Tried to find a straight piece of timber recently?

The first part to be folded was the rear floor. Seems to fit OK....

I had to also do my first but of "skilled?" metalwork to make a small dip so the bulkhead could fit snugly without fouling the seat-belt mount.

Love the welder, not a weld in sight. all very nicely folded, i will copy this...

MartinClan 28th August 2013 07:40

I have almost completed all the inner panels now. It's taken longer than I hoped but it's important to get these right as the floor in particular defines the shape of the body at the lower extremity.

It might all look quite simple but what is not obvious from the pictures is that many of the flanges have subtle curves in them. Getting them all to line up is the tricky bit!

That's some seriously impressive work - very nice :D Bending without a metal folder doesn't work that well as I found out when making the scuttle panels on the Sportster - a part I would redo given the choice.

garyh 31st August 2013 11:27

What thickness is the aluminium?

MartinClan 2nd September 2013 07:44

Ali is 1.2mm thick - as recommended by the instructions that come with the chassis. It seems a bit flimsy to start with but once you start adding a few bends and joins it soon stiffens up. One builder used 1.5mm but he struggled to form some of the panels using that thickness.

Floor now complete. Also fuel tank plumbing. Now onto the main body at last....

Nice plumbing, Robin!!:)

GreatOldOne 30th March 2014 11:16

Riveting... :) loving the raw aluminium with the copper tubing.

MartinClan 23rd April 2014 07:43

More progress! Trial fit of the first body panel. I spent a lot of time getting the floor right so it fitted without too much hassle.

And I treated myself to some seats. The standard seating is a simple bench but, unless you have a passenger, it means that you slide around a lot. These should do the job. The plan is to stagger them so that the driver and passenger shoulders miss one another. All the way from Canada. And yes - I will be fitting some squabs...

Progress
 
Quite a lot of progress in the last few months although it doesn't look it!
