Finally got the rear wheel in centrally with rear caliper and bracket  That really is old school  |

looks really good,
nice beefy swingarm and the spoked wheel compliment well.

That really is old school Cheers That was the plan 😁 Modern running gear that "looks" old Next job which I'm dreading and looking forward to the challenge is front brakes Need to work out adaptor brackets for the Lockhead CP copy calipers Thought I had found an easy alternative when I got offered some Harrison Billet 6 calipers that went straight on the forks but then found my discs were too thick for them Should be not too bad now that I've found you can buy a digital protractor Steve |

The Harrison calipers are super thin so pistons are shallow and not much meat on the 6 pads per caliper 😱  |

I know the discs are new but could they be skimmed/machined down to fit the calipers and remain within their safe working tolerances?
Or as you say sell the Harrison’s and offset some of the cost of new Lockheeds.
Joys of building a special bud 😉

Joys of building a special bud 😉 I don't have a set of Harrison's, I got offered a set of big piston billet 6's made for the Yam fitment I already have the Lockhead copies as that was my first plan I could have got ABE to make discs to suit but then I'd have to move on all I'd spent a small fortune on ☹ Oh and it's £100 for pads for the Harrison calipers 😯 Steve |

Totally mis read that one Steve and got your brakes mixed up. I thought you had actually acquired theHarrisons.
Lockheed’s all the way for that proper period look and awesome stopping power. Put a lightweight alloy one on my Norton and could not believe the difference. A brake which actually worked as the OEM one is total shite.
£100 for brake pads!!!!!!
Get some nice alloy adapter plates milled up for the Lockheed’s and never look back ( except when pulling out to overtake lol 😆)

Spent 2 hours making a template for the front calipers Would have been quicker if I hadn't dropped a pad pin. Still haven't found the little fecker 😡  |

That's looking good Steve Bit of CAD involved ?? Dusty No card involved 😆 Here's the technical bit lol I stuck a 2mm packer on the edge of the disc then put a piece of card (oh sh1t I did use card 🙄) behind each pad so when I sat the caliper on the disc it held in place with 2mm between the edge of the disc and the caliper groove with the pads on the very edge of the disc I then jammed the wheel with the other disc so the caliper was where I wanted it I knew the fork mount spacing was 100mm and the caliper mounts were 89mm and I could measure the distance between the 4 mount holes I then got my new toy out. A digital protractor 😀 I then measured the angles between the bolt holes and transferred the data onto some steel plate, drilled out and cut around 1 hole is 1mm out but I can sort it with the engineer when I give him the template to mill out of the big chunk of alloy plate I just bought 😁 Steve |

hard not to use top spec engineering aids like cereal boxes, twine and masking tape. if they produce a result, well winner all right.
bracket looks good

Could you not split the 6 pots and make up a piece to go in the middle, to widen them? Few O rings to seal the fluid passage and bobs your aunties live in lover.

I could but I don't like messing too much with brakes and the Girlings were the first plan anyway The yzf six pots and the tdm calipers off the leftovers build go straight on but I have literally no clearance I could get either to fit by getting new disc spacers made 1.5mm wider and take a flap wheel to the offending corner that just kisses the spokes and get 2-3mm clearance but if I'm honest that was only an option to save me the grief of making caliper brackets The template is done now so hopefully by the time the alloy has arrived the eng8neer will be back at work ish Steve |

Girling/lockheed/grimeca all the way matey (I assume girling made them first then Ap took over girling and Grimeca just copied them? sorry reversed engineered them?) either way for a build like this they are the nutts. Should i ever get round to buy the frame etc i need for my other build ill be using them.

Engineer still working on the adaptors. Popped down to see him today as some other bits he was doing for me were ready He's having a problem programming the bottom curve into the machine from the template as it's not a straight forward radius He looked relieved when I told him that shape wasn't important. As long as the holes are in the right place with enough meat around them it will be fine 😁 My clearance concern on the speedo drive to disc bolts ain't a problem any more Steve  |

Caliper brackets home to test fit for alignment before the fork mount holes are drilled/tapped Steve  |

Lovely bit of milling there Steve. Should look the biz once you get them fitted.
Polished or anodised ?

John Cheers John Would have been a lot easier to just use 10mm plate then spacers to sort the offset but wanted something more "solid" so went for the one piece May get a bit milled out the back at the fork leg mounts, never be seen but quite meaty around that area. In saying that it gives 25mm of thread for the main mount bolts Finish will be anodised. I'll scotchbrite the unmachined face first I had the pegs/levers and swing arm end caps/chain pull plates clear anodised so I'll get these done the same along with the 2 disc spacers and the rear caliper bracket Steve |

Fork mount holes drilled and tapped now and trial fitted The joy of hand made parts 🙄 Left one is perfect, right one just skims the outer edge of the disc 😖 I'll split the caliper and "relieve" the point it touches Was trying to get the calipers as far into the disc as possible as the 295mm disc is right on the max of the caliper With 1mm clearance the pads are right at the edge of the disc but that's what I get for fitting dust bin lids to 80's calipers 🤣 Steve   |
