CR 750 for road use build
« on: August 05, 2015, 06:01:51 PM »
Well here it is by popular demand,,,,well one person.
The build thread for the CR 750 replica build.
The frame is 1977 and I have cut a few of the brackets off and semi tidied them up.
The frame lock is ground out and welded over
As a guide I have ordered a seat for alignment of the centre bracket with the cut out for the oil tank cap that's to be welded back in.
But of course I have a CR replica already as a pattern for making all my own brackets.
I have ordered an ally fuel and oil tank but delivery is 9 months although I can cancel this at no cost if one becomes available sooner.

A few pics of my Cr in Honda colours

Keith - make your pictures stand out more by selecting "Inline full-size image" in the drop-down menu:

No more clicking to expand. (If I could set it as the default - I would!)

Made the two rear supporting brackets today, they need finishing off but the basics are there.
There based on the pattern taken from my other CR.
There's a lot of tidying up of the frame once all the brackets are removed.
My weldings not perfect but the japs welding is pretty basic

I was a CSWIP certified Welding Inspector (many years ago) so I have seen 'a lot worse' in my time. Whiz over it with a heavy duty spiral wire brush in an Angle Grinder before painting and it will come up lovely. I was brought up to remove all burrs, weld spatter and similar imperfections before painting during my Apprenticeship, and I now find that when doing minor maintenance tasks that I spend just as long cleaning and repainting the bits...... well........I am retired - so I have the time.

Years ago I worked for Ingersoll rand (Compressors) in Trafford Park, Mancunia on Sea. I worked with a Painter - who told me that years before, he had to put filler over the welded seams on Air Receivers (tanks), then smooth them off before finally painting them. He was known as a 'Dauber' by the Yanks (it was an American Company).

Great to see a Forum member taking on a 'different' project and hope to see regular updates and photos. Best of luck in your endeavours.
Now: 2008 CB1300S, CB750K4, 1970 Bonneville. Various other 1960's 650 Triumph T120's/ TR6's/ TR6C's (all in bits...many, many bits unfortunately). Previous: 2007 CB600FA, 1976 CB500 Four. BMW F800ST. GS750E. ZZR1100. CB1300 (2). ZXR1200S. VFR800. CB750 Nighthawk. CX500. XS500 Yam. Suzuki GT500. BSA A10. Various Lambrettas. Zundapp Bella (honest).

Thanks for the replies, funny you mention ingersol rand as I run a compressor co. We are the main distributor for HPC .
I will also spend many hours in the workshop cleaning those welds it's worth it in the end but I won't use any filler.
The CR project will only be done as and when as the rickman 750 project is currently waiting for other bits and pieces.
I like to make as much as I can and not buy it in.

Made and welded in some more brackets yesterday.
Still lots to do but there's no rush

I need now to cut the section out for the oil tank filler

Rear bracket removed, which will be re used in its new location.
It's ready to cut the back off the frame tubes
Top oil tank fixings made and fitted into position

Although every care is taken when removing brackets to avoid any twisting or frame distortion I
supported the frame with studs etc . But I will at completion of the alterations get the frame checked so its straight.

Seat arrived and it fits a treat
Welded the front fairing stay to the headstock.
Screwed a plate over the the serial number so that when its shot blasted it won't destroy the numbers

Hint, leave the plate on when it is powder coated or painted as the MOT man like to read the stamped numbers---In fact according to VOSA he HAS to read the stamped numbers
