Trumph 1940 Speed Twin

[Dexter]

Thanks to all the contributions to date some interesting reading.

On the rear wheel its has been reassembled and no pictures but it has a tapered bearing like the fron one side and a centre sleeve and a sealed bearing the other side which was changes as it felt past its best.

No plans to strip the engine yet, from the info I have from the old owner its spent a lot of time unused between races and then layed up before my purchase.

The magneto has been set off and had a broken winding which will explain the poor starting so this is coming back with a full rebuild.

Most of my latest work has concentrated on finishing off both front and rear wheel, I took a long look at the rear mudguard but just hated the proportions of the stays and the guard looked a bit like swiss cheese so I took the decision to replace both which would allow me to change the clearance of mudguard to tyre which I wanted to reduce. I have remade the stays in a similar fashion but with smaller proportions.

Mudguard to frame mount


Stays with a welded extra plate of 5mm added at the end which are threaded so just a bolt required.


Assembled

Played with the front brake duct - this has been welded on so not the best mod by a previous owner and the square end was not doing it for me so a slight mod.

Dexter- are those stays alloy?

Yes alloy 2mm thick with a further piece 5mm thick welded on so its thick enough to be tapped for a fixing ( not yet drilled in these photos ) and also the 5mm step helps to set it off and miss the curled edge of the mudguard

Nice work! I've always been worried about alloy though, for reasons of vibration causing work hardening, then eventual fracture.
Last time I did something similar, I used the tubular steel stays with crimped ends often used on bikes of this era.I like what you've done, though.

Thanks if it do enough miles to brake it I will be proud to fix it.

Dexter-you are now the custodian of one of the world's most beautiful bikes- it's your canvas, and a fabulous opportunity. Do your own thing always! I'm sure you will do it proud.

[Dexter]

Thanks Hoghead

Refurbed Mag arrived back and is now fitted pretty much started on the first kick so seemed a shame not to get some pictures, its been ridden up and down the road but awaits some better weather to go on a proper road test, also make some new foot peg hangers so this may delay things.....

[Hoghead]

Excellent! The weather has been really crap lately. I had e3134 cams in my old t100-used to pull well.

New side project Dunlop seat build

[Hoghead]

Looks like a nice find! My ex wife had a Brooks saddle on her Calthorpe, that was a nice piece, complete with brass tag.
Part of the joy of old bikes is finding period parts to use, we used to spend hours trawling for stuff at autojumbles.

Re-appropriate......

This bike is really starting to look awesome!

[brumble]

Man, that bike is so cool.

Good to see that it's in good hands.

Do you have any audio of it running?

Hi Hoghead

Pm sent much appreciated

[Dexter]

Ok so next thing on my list was to replace the ali foot peg hangers. There were ok but I didn't like the proportions, could have carved them up but some of the size was providing the strength so an alternative was required

As they were


I turned up some bosses and bought some seamless tube and new folding pegs and made these - the colour match was not spot on for Amaranth red but lest say the frame may have faded in the sun.... fat chance in the UK
