Marco,

You asked above about how to "wire the edge" of a flat panel, to enclose a wire for stiffness and to protect the fingers.

See: http://wiki.dtonline.org/index.php/Wired_Edge

Looks like you allowed a little too much for the wire. As said on that page it's 2.5 x the wire diameter.

Good luck!

John

 

Good bench mark allowance 2.5 times.

for specific angles in differeing material thicknesses the   Bend allowance tables are your friend.

Hi,

sadly this project is very slowly growing....

[RobH]

Looking good though, Marco. Ready for the 2024 season?

[Z320]

No doubt!

[RogerH]

That has a sleek beauty.

It should be on the bonnet

Hi Marco, 

check this one out on wired edges - all you need is a hammer!

John.

Thanks all for advice,

but to safe time I very likely will not do the wired edge.

It would just be a challenge to do, but there is no really need for it at the rear or front end of the cover.

Wired edges went out with the end of TR3B production Im afraid.

nice workmanship Marco. 

[Motorsport Mickey]

Excellent work Marco, your problem solving skills have come to good use here.

Thanks all for your laud,

that gives me some new drive and a good progress for today

My idea is to make "the bell" butt-welded (correct term?) or hard soldered, but all other parts connected with overlap and rivets.

Another great project Marco. Always something to learn from your work.

Marco,

I don’t mean to be nosey, but…

What is that thing in the photos, up against the wall, with all the pipes and green taps attached.

And what does the tray do that is underneath them?

And the tap at the right-hand side. What is that for?

I just can’t work it out.

Charlie.

[john.r.davies]

Very nicely ("nicely" = exact, well fitting) done!   But Marco, where does the stick go?

That is our trinking water distrubtor with 3 lines (cold water gerneral, cold water refill of the cistern, cold water to trinking water boiler)

The tray is to get the lines empty in the case of a repair via the small green taps, the tap right is 3/4" with a "Gardena" fitting (shure you know) to plug a hose.

Right is the pressure reducers with back flashable trinking water filter.

Cut out I make later suitable to the MX5 shifter housing, currently the gearbox is out of the car

[john.r.davies]

Ah! Thank you, Marco!

And there was me thinking you had gone for a ZF 8 speed auto.

I think that’s the gearbox in my BMW 650i , slinky smooth, and very punchy in Sport and Manual modes, bit different to the TR3a !!

[Z320]

Slowly the project is growing, I need too much time for it.

The red marked edge is to high for the H-frame and need a modification...
