Well the rear is now pretty much complete. Just need to add the lights and then that's it. As you can probably see there were hundreds of rivets to set and, just to make it even more interesting, the rear top panel is also bonded with epoxy resin. The result is very strong!
That just leaves (bodywork wise) the dash top and bonnet to do. Light at the end of the tunnel at last.

Lovely work, where did you get that edging? Are you painting the car or just polishing it?
|
I am hoping to polish it if I have the patience ;-).
The edging is the same as used on the Morgon 3 wheeler. Fellow Pembleton builders used to have a source but unfortunately it seems to have dried up.... Cheers, Robin |

Is that very shiny thing the silencer?? |
Yes. 1 per cylinder. Good job it's not an m20 lol.

Some more progress despite the fact I have been also spending some time fault finding on the Sportster. I have made a prototype of the drivers side dash top, cowl - call it what you want. It's not bad for a first attempt although I will make it again now I have had some practice.
The flange that fits allong the dash hoop has to be stretched in order to get the shape. After evaluating various methods and tools I have used the old fashoined way of belting it with a hammer. Ok - so it's a special stretching hammer - but much cheaper than buying a proper shrinker/stretcher as used by some bodyshops. The marks left by the hammer will be hidden by the bonnet tape. I have shaped the cowl in such a way that it covers the steering wheel thus hopefully preventing hands getting too cold. bending it in such a way means it is suprisingly strong. Even so I will be re-inforcing the edge with a U shapped ali trip strip.

I have completed the scuttle top. In the end I gave in and bought a shrinker/stretcher to make the flange. And to answer my wife's question (lol) yes it is supposed to be asymetric! The offside has been modified to follow the outline of the steering wheel.

Light at the end of the tunnel! Cheers, Robin |

Beautiful workmanship it will be a really stunner when finished. Can I just ask , was this bracket made of aluminium ? Not a kit car builder myself yet , however have done loads in the bicycle world and we gave up on aluminium for brackets as the weight saving is negligible and if something is going to break with load and vibration it will be the most awkwardly placed bracket. regards Paul |
Thanks for the encouraging words Paul :-). No the bracket is made from a bit of galvanised steel I had hanging arround the workshop. Hence the funny colour!
Cheers Robin |
Bodywork complete excpet for the cycle wings. Not long now.... (90% complete and 40% left to do :-) )

Robin
This is looking superb.............it will be really nice to see it on the road. How far from IVA are you realistically? Mike |
Some nice panel work here Robin, a friend of mine at work has just made himself an English Wheel for forming petrol tanks and panels for the motorbikes he builds, we made him the top roller and he purchased a set of bottom rollers from the net and incorporated an old lathe tail stock to adjust the bottom roller, it works a treat, maybe one would have helped you out on your panel shaping, they don't leave hammer marks in the material.

Great work Robin. Really like contrast between the aluminium body and the brass nose. :)

Middle of next year I hope if I don't pontificate (fart arround) too much... It actually requires an MSVA (Motorcycle Single Vehicle Approval) test as it qualifies as a heavy trike. Much less onerous, although it still has the infamous radius test, and far cheaper :-) Cheers, Robin |
Fitted the wheels this weekend. Not quite so simple as it sounds as the wheels and hubs are combined. The wheels are made by Pembleton by machining down the 2cv hubs. Makes for a very low unsprung weight which should contribute towards the handling. Riding a bit high at the moment....

Looks awesome :)

Stunning.

Mudguards
I am trying to do something clever to support the mudguards as they rotate. They are very light being made of aluminium - much lighter than the Marlin. Even so I want to design out the bouncing up and down I get on the Marlin.
So I have been doing some experimentation trying to find the rotation centre by extending the line of the king pin up to the top of the tyre.. https://farm1.staticflickr.com/571/2...e05711a5_c.jpgDSCF2078 by Robin Martin, on Flickr https://farm6.staticflickr.com/5720/...5b900fec_c.jpgDscf2079 by Robin Martin, on Flickr Looks a bit Heath Robinson but I think it's done the trick. I also made some MSVA friendly covers for the ends of the suspension arms. https://farm6.staticflickr.com/5726/...86795225_c.jpgDSCF2081 by Robin Martin, on Flickr They clear the bodywork by at least 2mm.... Robin |
Nice

Having considered a few options for the wing stays I finally decided to make my own. I wanted a design that was light and stiff. didn't require any welding (in my experience welding is nearly always the weak spot of any wing stay), was easlily adjustable and didn't cost a fortune.
After a lot of head scratching I came up with this. It fulfills most of he requirements! There is a tiny amount of "woibble", but far less than the Marlin and it cost less than a tenner! https://farm2.staticflickr.com/1664/...64af006e_z.jpgDSCF2096 by Robin Martin, on Flickr https://farm2.staticflickr.com/1675/...2e70e662_z.jpgDSCF2100 by Robin Martin, on Flickr Cheers, Robin Electrics next! |
Nice work, Robin!!

MartinClan - This really is a beautiful build. :cool:

A bit off topic but just bought a new toy....
https://farm2.staticflickr.com/1648/...88170b09_c.jpgDSCF2103 by Robin Martin, on Flickr It's very old but the bed and leadscrew are both in good order. I have to fettle it a bit before it becomes operational - it needs a mounting divised for the motor and countershaft both of which were fixed to the wall of workshop of the previous owner. Once it is up and going I plan a rolling restoration to get it back to its former glory. Cheers, Robin |

Not a lot of updates recently but the car is now close to complete. (Well closer...).
Here are a few pics of the electrics and the final arrangement for the front cycle wings. Fuse and relay box at bootom of glove box https://c2.staticflickr.com/2/1558/2...c3a61e64_c.jpgDSCF2115 by Robin Martin, on Flickr Everything connected with multi-way plugs https://c1.staticflickr.com/2/1471/2...bd732bee_c.jpgDSCF2109 by Robin Martin, on Flickr Dashboard. Ballast resitors are to compensate for LED indicators https://c7.staticflickr.com/2/1703/2...9fe743c0_c.jpgDSCF2107 by Robin Martin, on Flickr Engine electronics - a bit simpler than the Marlin https://c5.staticflickr.com/2/1584/2...9096e318_c.jpgDSCF2111 by Robin Martin, on Flickr Front cycle wings. Considerably more stable than the Marlin https://c2.staticflickr.com/8/7560/2...87c27fa8_c.jpgDSCF2117 by Robin Martin, on Flickr Cool LED indicators (cheap as well!) https://c1.staticflickr.com/8/7250/2...0d7ba892_c.jpgDSCF2118 by Robin Martin, on Flickr Robin |
Really neat, looks great :)

Nice work, Robin!

Almost ready for the MSVA and an alternative use for an old wine storage box...

A nicely done Pembleton here in the USA

Awesome :) Very nice :)
|
MartinClan - Your Pembleton looks great and I like the tool box idea. :cool:
Good luck with the test, Paul. :) |
[QUOTE=MartinClan;85586]Almost ready for the MSVA and an alternative use for an old wine storage box...
Very nice... What are your plans with respect to covering up the front with a 'cage' for the test? |
MSVA passed today - yeay. A few pictures to follow shortly....
Robin |
Congratulations!
|
Great stuff, Robin! If you could post details/photos of the front cover, I'd find that useful...... If I ever get to that stage with mines 😀
|
Well done Robin :)
