Rosco 1st February 2015 07:31 PM



Then a mk1 gear lever, just as a starting point






Rosco 2nd February 2015 09:10 PM

Got a bit done tonight, made two hose barbs for my fuel tank



And drew my fuel tank up ready to get it laser cut and folded



Also my mates started on my silencer, it's repackable


Rosco 4th February 2015 07:43 PM

Few hours tonight but was getting cold!

My tube for my fuel tank came today so made a bit for the filler and the larger bit for my swirl pot/ pump houseing, also drilled and tapped the pump flange



Also Picked up my exhaust flanges and collars tonight ready for making my manifold


Rosco 15th February 2015 02:59 PM

Well I've been doing a few jobs since my last update, my fuel tanks well on its way, I've been drawing up my pedal box for the last few weeks and
I've spent all day on it today, pretty happy with it, should get it cut out next week, I was going to use Vouchts pedal box design off the haynes forum
But with the bias bar and different cylinders I just couldn't get it to work, all my ratios have work out as I want them, so all being well it will be sweet

The pedals will have tubes in between them





Also my mate sent me a pic of my exhaust collectors, possibly doing my manifold with him next weekend




Rosco 15th February 2015 06:58 PM

Drawings ready for my laser man


Rosco 21st February 2015 09:11 PM

Well had a awesome day today! Been up and seen my mate at Primary Designs in Thame today, was a long day but we got my exhaust all fabricated and tacked up, he's going to get it finish welded during the week, the primary lengths are all within 5mm! I will let the photos do the talking








Rosco 21st February 2015 09:12 PM






Rosco 10th March 2015 08:36 PM

Right no updates for a few weeks, still waiting on laser cutting and to get my exhaust back so I've got a little side project to keep me busy

Ive been after this for about a year as it's been sitting in a blokes yard, he finally sold it me last Saturday afternoon



I borrowed a trailer to get it home on, but it weighs about a ton so we had to strip it to get it up the garden!

The bed took 4 of us to lift and so did the stand



Gearbox was mint



Loads of bits to clean up


Rosco 10th March 2015 08:36 PM







Base and bed ready for paint


Rosco 10th March 2015 08:37 PM

Clean parts bin filling up



Covers and parts ready for paint




Rosco 10th March 2015 08:38 PM

Parts painted by my dad while I've been at work







And that's where it's up to, cheers for looking

Tatey 11th March 2015 01:01 PM

Build is looking very good Ross and lathe is a stunner now it's painted!

How are you planning on stopping the pedals from falling forwards? I only ask as I have now got to the stage where I am finishing my pedal box, I've found the polymer bushing with 8mm bolt through it to be a poor pedal pivot solution when used with the bent brackets to stop the pedals falling forward.

You need to the pedal pivot bolt loose otherwise you end up clamping the pedal to the pedal box but the bent brackets need the pivot bolts tight to provide enough clamp load to prevent them from rotating.

To solve this I'm going to make some crush tubes (1/2" OD) to fit inside the bushes (drilled out to slightly larger than crush tubes OD) which are slightly longer than the bushes (about 0.5mm either side), meaning the pedals will rotate about the crush tubes instead of the bolt. This is the same method used for the suspension bushes but I'll have a bit more clearance between the crush tube OD and the ID of the pedal bushes so that its a smooth pedal movement.

I'll let you know this weekend if it works as expected :D.

Cheers mate, I'm going to look at it when the box is together, maybe alter a pedal side or something, is it a requirement for iva? I get what your saying about the crush tubes but can't you just weld the stop to the side mount? Then bolt though as before?

Tatey 12th March 2015 09:17 PM

I believe it is a requirement, but not 100% sure, however you really will want front pedal stops as the pedals fall forward really easily which could get interesting if you're out driving.

I wouldn't recommend welding the pedal stop to the side mount as you then can't adjust it meaning you might end up with a lot of travel before getting tension on the cables or constantly tension your clutch/throttle.

I've seen others that have welded stops onto the outside of the pedal and used bolts through the floor the same way the brake pedal works.

I made the mods to my pedals and it works a treat.

SeriesLandy 12th March 2015 10:21 PM

I used these olive bearing bushes with a stainless crush tube and they are perfect. Stiff but still easy to move as they are self lubricating.

flyerncle 13th March 2015 08:00 AM

As above they are the same on mine and work a treat,you can force oil into the bushes too.

Rosco 20th March 2015 07:38 PM

Well the lathes almost there, new motor fitted, just a bit of wiring up to do





Also I've got my exhaust back all welded up




Rosco 20th March 2015 07:39 PM








Rosco 20th March 2015 07:39 PM



Going to use these rubber mounts I think



I'm a little worried about the clearance between the exhaust and my grp side panel, the gaps 15mm at the min




Rosco 20th March 2015 07:40 PM

I'm happy with the silencer position though



Can anyone comment on my clearance issue?

Rosco 30th March 2015 08:56 PM

A bit of an update tonight, I was looking on speedhunters today like I do most days, and they decided to do a little wright up with some pictures I sent in

http://www.speedhunters.com/2015/03/...owered-builds/

It's about half way down

Next on the list, the lathes all finished



Also I'm back on my pedal box, should get it all tacked up this week



Clamping the sides up square




Rosco 30th March 2015 08:57 PM

Pedals





Flange bearings for the pivots



All the tubes will be tig welded in

And that's it for now

dubzter 30th March 2015 09:00 PM

that pedal box looks amazing, keep up the good work :D

Tatey 30th March 2015 09:30 PM

Lathe and pedal box are looking good Ross!

One quick question, it's probably the angle of the photo, but will you be able to fit a cap head to the bottom master cylinder mounting holes as the brackets look a little close?

metal matt 30th March 2015 09:32 PM

Now that is a fine bit of fabrication if I do say

Cheers for the comments, it's going well at the min!

Yeah there's just room for a bolt :)

Rosco 1st April 2015 10:21 PM

A bit more done tonight, I made some exhaust hangers at the weekend and my rubber mounts came today so got it all mounted and tacked up









Pretty happy with how it's worked out, sits where I want it to which in good

flyerncle 2nd April 2015 10:31 AM

Porn in metal that pedal set,shame it wont be seen.:(

Rosco 6th April 2015 05:13 PM

Had a good few days on the car this weekend, got a bit done

Pedal box tacked up and in the car, there's still a bit to do on it but at least I no where my seats going







Front seat rails done, I've raised the front of the seat to lower the harness holes at the rear


Rosco 6th April 2015 05:14 PM



Nuts welded underneath



Harness mounting bosses made




Rosco 6th April 2015 05:14 PM

Rear diagonal done



A shot from the rear, also a bit of artwork put up!



Also I've set my self a date of Easter next year to be Iva'ed and on the road

Rosco 12th April 2015 01:48 PM

This weeks progress

I started working out where my lower harness mounts were going according to the msa blue book



I've changed the book design a little, tacked in





Centre two


Rosco 12th April 2015 01:49 PM

Upper seat brackets done, I no the top edge doesn't need a radius behind the seat, but it looks neater I think



Just need some side to side spacers sorting and some correct length bolts



Next throttle cable sorted and temp return spring and the studding through the top is a temp forward stop



Full throttle


Rosco 12th April 2015 01:50 PM

Clutch cable



Full clutch



I made two tubes to hold the outer cables



Next job, the rest of the roll cage, I've decided to mount the front hoop on the outside, as bashing my leg on it all the time not my idea of fun

I mocked up the scuttle panel, and worked out a mounting plate



The tube will mount to a bit of tube on end with two more bolts so it meats msa spec, once the front hoops in place I will sort my roof bars and door bars out

scutter 12th April 2015 06:29 PM

Dude, still mighty imprressive. Makes mine look like it's being built in a cowshed.

ATB Dan.

Ianr 12th April 2015 06:46 PM

Daren't put any pics of my poorly built badly engineered thing on here, it'll be compared to this engineering master piece.

Brilliant bit of work Rosco - not that much different in build progress to mine really but I want to get mine on the road for 2016 kitcar show, fancy a race???

:)

dubzter 12th April 2015 10:11 PM

Awesome work, looking forward to seeing how your roll bar works out as that is something that is really playing on my mind

Yeah it is mine to be fair, I think I'm going to mount it on the outside i think and welded on, I've had a quick draw up of it, but I'm going to mock it up with plastic pipe while I'm sat in the car


flyerncle 14th April 2015 08:21 AM

Excellent tweeks to original Gibbs design.

What would it be like to syphon off all the excellent upgrades builders have made and put them into one roadster .:cool:
