The problem we have is that the local non ferrous foundries are not interested in one offs. We might of got it sorted by calling in a favour before we go traipsing across the country.so we will wait and see. 7 minutes ago, PITT24423 said: Cheers Thomo, this casting is pretty poor on the coolant side which we have blasted several times with it sweeting after each occasion lifting off another layer each time .Leaving us two options two pack epoxy which we have successfully used before or cast new.

All the original bearings are Hoffman who were based in Chelmsford where as the bearings in the lorry were Swiss . New bearings are all on order and due in this week. We will do the same as we did with the lorry and fit double lip seals with the minimum of modification as I personally prefer to have things as oil tight as possible in our environmental sensitive world. After numerous under coats the wheels have gained their first top coat which in my opinion has changed their visual size and appearance for the better. Hoffman Bearings must have been a pretty big company and were used in many high class vehicles. My 1929 Rolls Royce 20/25hp. has Hoffman bearings throughout. This is the outer left front wheel bearing. Not too sure what I will be replacing them with at this stage. 1 Quote Link to comment Share on other sites More sharing options...

True if you use tap water only or a average antifreeze. Shuttleworth were (maybe still) using a Honda coolant in the aircraft because of the inhibitors and I know others use deionised water which is why I choose to use the waterless coolant as it ticks all boxes with no expiry date. The problem with it is that it finds the slightest hole or crack which more often than not wouldn’t leak with conventional coolant , so you need to be water tight from the off. 1 Quote Link to comment Share on other sites More sharing options...
Citroman Posted December 15, 2020 Share Posted December 15, 2020 Here just over the border at the Aachen technical university they can 3D-print metal. No one like that in your area? 1 Quote Link to comment Share on other sites More sharing options...

No one like that in your area? You can order 3D printed aluminium online. But it's horribly expensive: https://www.shapeways.com/materials I looked at having an inlet manifold for a motorcycle cast, and it would have been £1200. However, I think that the main part of the cost is the overall volume (and especially height) so the pump parts might be worth investigating. 3D printing a pattern for conventional foundry casting is probably worth considering, though. We have a couple of Aluminium printers at work, but sadly I have not found a way to sneak my parts on to them. 1 Quote Link to comment Share on other sites More sharing options...
Citroman Posted December 16, 2020 Share Posted December 16, 2020 You should try a hobbyist or a college with those techniques. At the university they were happy to make a part for my friends antique grammophone. Otherwise they were printing dinosaurs and stupid things like that. 1 Quote Link to comment Share on other sites More sharing options...
PITT24423 Posted December 22, 2020 Author Share Posted December 22, 2020 Foundry located inNorfolk who are going to cast the pump casting and the radiator side castings in the new year. Gearbox bearings and seals arrived so I can think about getting the box back together over Christmas . Back axle stripped and blasted so I can start getting “ diff “ inspiration hopefully scheming something out of what oily lumps of diffs we have accumulated. Repro nuts and bolts arrived caught me out how long it took to swap with the temporary bolts. Fuel tank fittings freed off and cleaned, realised the fuel cap had been repurposed to the Kiwi made gearbox top. Luckily we have spare gearbox caps as they are the same as the diff oil level cap . The tank is away now being acid cleaned as it looks as if it has had its share of H2O .Apart from the newness hard to tell the difference between the rivet bolts and rivets. 3 Quote Link to comment Share on other sites More sharing options...
PITT24423 Posted December 30, 2020 Author Share Posted December 30, 2020 Chassis given a few coats of top coat in between festive eating and drinking. Body jacked up and trolley removed ready for chassis marriage tomorrow , all of a sudden it looks a bit on the tall side. In theory it’s about 3” higher on the stands than it will be on the chassis for real minus a bit for spring compression. 6 Quote Link to comment Share on other sites More sharing options...

PITT24423 Posted January 18, 2021 Author Share Posted January 18, 2021 Nothing spectacular to report other than lots of loose ends to tidy up. Seat backs retaining straps folded up and painted. Drivers steps fabricated and fitted. Drivers floor frame made to determine pedal positions. Started to set out seat box with limited information available. Cracking photo in Bill Wards book of Daimler bus bodies laid up for the duration of the Great War .A bit of polishing has gone on under the bonnet. 6 Quote Link to comment Share on other sites More sharing options...
PITT24423 Posted February 7, 2021 Author Share Posted February 7, 2021 Rear springs fitted with new bushes and pins which were made oversized so we reamed the shackles and hangers to save making sleeves . Rear axle fitted and brake actuators which were stripped and cleaned earlier refitted.Started to set out staircase and will be a combination of templates from a restored B type and a London General Omnibus drawing we have which is so close to the Birch Brothers body we have . We were lucky in the fact all six of the original electric light fittings survived but unfortunately none of the glass lenses. A friend had some almost identical but the lenses are a fraction larger . I have now found a company who can replicate them to the required size but still have to find someone to cut the star in the bottom. We now know this is a early body which was lit by gas (carbide) and converted probably around WW1 to electrickery. We are now looking for a Lucas electric conversion for the oil lamps which was a bulb holder which screwed in place of the red lens in the back of the lamp.I’ve had these lamps on the shelf waiting for a permanent home for over twenty years which are probably originally for a car being a single spade whereas we should have a fork fitting but it is a case of I have them and they are complete. 3 Quote Link to comment Share on other sites More sharing options...

PITT24423 Posted February 14, 2021 Author Share Posted February 14, 2021 Top deck seats finally finished and fitted, can’t believe how many hours they have collectively taken , just about all of us are seated out ! Felt seals turned up for the king pins and front wheels. Rear wheels,we will machine out the felt seal carrier to take a lip seal as this has proved successful in the lorry and a unseen mod .The brake shoes are away being relined with a superior lining matched to the drums so hopefully the brakes will perform better than ever once bedded in. Stair set out and pattern stringers cut out of 4mm mdf to double check all is well. Simon drew up what we had created with additional radius’s to replicate the drawings we had as a dxf file for both stringers and will get lazer cut later this week out of probably 18g where as originally we think they were 20g . Reason for increasing the thickness is to improve strength as everyone appears bigger than their ancestor . 8 Quote Link to comment Share on other sites More sharing options...

PITT24423 Posted February 15, 2021 Author Share Posted February 15, 2021 Thanks for the previous two posts of help but fingers crossed i may have this one covered now as theres a resident old bouy engraver at the other end of the island who has hopefully going to engrave the lenses for me .Plan B i`ve got some spare lenses being blown to cover all bases if the worse was to happen . 1 Quote Link to comment Share on other sites More sharing options...
PITT24423 Posted February 17, 2021 Author Share Posted February 17, 2021 A bit of luck as a correct period Hackney carriage plate was flagged up to me on our favourite auction website These plates were issued to buses until the 30’s by the Met Police in a similar manor as they still are today for taxis. Apparently the crown alternated yearly with the unicorn and lion crest. If anyone can add or knows if any of above is incorrect please let me know and I’ll correct the text, thanks.

PITT24423 Posted February 21, 2021 Author Share Posted February 21, 2021 Borrowed a former from a friend which I adapted to make the rear mudguards which we successfully glued up three layers of 4mm ply this afternoon with the proof being tomorrow when we release all the clamps.Will glue up the second mudguard later during the week . A bit more luck in that another friend unearthed a pair of headlamps which arrived this week which share a close resemblance to the ones originally fitted to CBs 4 Quote Link to comment Share on other sites More sharing options...
PITT24423 Posted March 14, 2021 Author Share Posted March 14, 2021 Started to seriously think about the diff as this proved quite painful for the lorry. I was lucky in that I was able to get a second axle which had a top casting. Over the years I’ve picked up the remains of worm drive diffs on the off chance and today it paid off in a monumental manor. I need a ratio of 7.25 to 1 = 29 teeth on the crown wheel and a 4 lead worm . I cleaned up the top casing a while back and had measured one of the spare diffs with a hunch that looks close but with 26 teeth. Undid the four clamp nuts and low and behold it dropped straight in as if it was made for it without even requiring new bearings.Our suspicion is that this diff is American possibly Peerless . The plan is to use the diff centre and get a new crown and worm machined .I’ve been recommended a gear cutting firm that can cut from a copy so we have stripped the diff out of a Daimler CC we finally got home this week to use as the pattern inc the worm. Mudguards bolted on which added a some distinctive style. Graham the spring did his bit and made new brake shoe springs which tidied up the pile of shoes. 4 Quote Link to comment Share on other sites More sharing options...
