Finished the repair on the carburettor float lid and made a new banjo bolt to suit the smaller thread diameter into the float lid.

Some nice simple machining work there

Indeed, a modified m16 stainless steel bolt

Sorry to see the result of the pulley to radiator mishap.

Things happen…… But not sure why in this instance?
Had a think and rather than draining the power steering fluid to remove the pump I think I’ll machine a new fitting for the pulley.
A good .05mm undersized then heated to expand for an interference fit.
All I can think is I damaged the original by pushing it off via a hydraulic press removing a fraction of material.

Above shows my repaired carburettor float lid with the new banjo bolt fitted. I’m happy with that. Doesn’t leak so perfect

Below shows the brass plug I machined to stop the leaking brake fluid from the brake line bias differential. Basically if a brake line leaks and loses pressure. A cam inside the unit slides over and operates a switch to turn a warning light on between the main dials. Problem I have is the seal has gone on the push on electrical switch and hence leaks brake fluid. New rubber sealed electrical connections for it are not available so it has a bung until I repair the leaking seal

Such engineering skillz, I do hope you enjoy driving the finished product.

Thank you, I’m sure once complete it will be a pleasure to drive

The power steering pulley issue I’ve been repairing, well tried to. I thought to sleeve the original pulley mount. Machined well but my bore micrometer ran out of adjustment to measure. I did the fatal error and assumed the finished dimension on the previous cut plus the last cut…..doh!
Got it red hot to fit over sleeve and it just got stuck and that was that. Massive hammer to remove and I thought it’s bent now so start again. Pictures below show newly machined part with the nfg original part.



With the pulley removed the mount will heated red hot then fitted onto power steering pump drive shaft. Once cool, a clean, coat of satin black and then the pulley can secured to it. I’ve used 3 new stainless steel hex bolts, machined the tops flats and given them a quick polish to add a bit of shine.
