Great project! I have a Merc SC ready for the MX5 engine. I did figure out how to drive the electronic bypass from a signal generator hooked to a vac sensor, but in the end like a good few others decided that the Mini Vac driven one would be easier.

Just one observation is that a lot of your earlier welds and some of the later ones look "cold" from the pics. Also as if you have not cleaned back to bare metal. Did you hammer test some of them? MIG can be a bit deceptive in that it looks great but if it has not penetrated it might as well be Pritt stick. - The ones holding the gearbox on look good though! You can get a much more experienced opinion if you post samples on the very friendly MIG welding forum.

Miskit, no problem with the welds as most of them have had atleast 2 passes in structural areas.

They are thick and messy but strong mate.

Looks about as much fun as it was :/ on the plus side all of the heavy fab work is nearly done. Just the N/S footwell to plate, rear wishbones, scuttle and the diff mount to finish and the rest should be bolt on bits. (I hope!)

Thanks for the compliment.

I know the weld comment was constructive, it could have been a real saftey issue if the welds were dodgey.

On most thin stuff I do two or more passes to ensure that any defects/holes are burned up and sealed. Makes the welds look lumpy but I would rather grind back than snap off lol.

Did abit more today...

I found a new shape mini steering coloum on ebay for £20 with next day postage. I have stripped/trimmed all of the adjustable junk off it. Much smoother and more robust than the merc donor one.

Like that mini column, tidy bit of kit!

What's the screen ?

How's the loom on the Merc - split or all in one bit? I am just finishing up the MX5 one, extracted what I needed for the engine to run and removed 20kg of the rest. However even on a 2002 MX5 on top of the engine stuff it still needs the vehicle speed sensor (I'm not using the gearbox so had to improvise), clutch sensor, brake sensor, atmospheric pressure sensor. and one exhaust sensor to run properly. I would imagine the Merc needs all that and more!

EDIT - Sorry just noticed waaay back on page one you said you were going with an aftermarket loom

What is the bottom uj connection like to the rack, spline or keyed? Looks neat, will it connect direct to an escort rack as looking for a new one

Gents, sorry about the delayed responce. Things have been manic at work.

The mini coloum is keyed not splined so I had to knock up a bottom section to link it to the rack. Have a 16mm rose joint in the post to finish it off. Have had to cut/weld a new spline on so I can use the removable boss (nightmare of a thing).

The screen is a old tablet from work, thought it would be nice to have satnav, gps, and real time engine info to hand. Would also be a nice modern touch to put into it. Torque pro and other similar app's have quite a few cool features to play with.

Has been a quiet couple of weeks in the garage thanks to work trying to ruin my life on the night shift nightmare.

Have started the firewall and heat sheild for the cone filter (still needs a couple of bends and fixing in place).

Have finished the steering coloum and rack so thats one thing off the list.

Have also started to run wires to make up a loom.

Oh and I have made up a little storage tray so im not losing phones every couple of miles

This project looks to be really taking shape now.

Love the updates.

And you have also proved one of my beliefs, 'You can use Uni-Strut for anything'... Marvellous stuff!

Although I have sold mine, the interest is still there...

Ian,

Thanks mate, has been a world of hurt getting to this stage and its almost looking like a car now (yay).

And agreed uni-strut is great stuff, has got me out of a few problems now.

Abit off topic but I brought this beast to refurb. Should be more than ample for a sandblaster


Disaster struck when changing the fittings on the regulator so I had to get a new one.



Have used my little borescope thing to check the inside of the tank and she seems solid. Now its time for the strip down and paint.
