lewis onionsHi Will. Assuming you have a standard 532 cc engine rather than a Squirrel engine, the design drawing for the pistons is in the technical section of this site. I referred to it when the engine on my 1923 was being rebuilt earlier in the year. It has sll of the diemensions.
Cheers
Lewis
lewis onionsWell if you make it to the Club stand at Stafford this weekend …….
lewis onionsOr simply look at the Lucas Equipment brochure in the documents archive on this site which includes a wiring diagram.
lewis onionsAfter many months’ delay waiting on parts and engineering services, the Pile of Junk is back on track………
lewis onionsSad news. Clive was the very best of that genial type of extrovert that you find mixing with old cars and motorcycles. I visited his farm in the Staffordshire moorlands on several occasions, and I never left without having been indulged with the gift of one of his over-sized cigars. I often went to collect his Reynolds Special for display at Stafford Show. On one occasion he jumped into the beautiful Lagonda (which started on the button) to free the Reynolds from the back of the garage and rapidly reversed it straight into my bike trailer, whilst I waived wildly to him to stop. He jumped out, surveyed the crumpled wings, shrugged and carried on as if nothing had happened !
lewis onionsA 2-speeder’s kick starter is very different from a conventional kick start on a later bike, even the Flyers. It is fragile and does not need a “swing”, rather a little dab with the foot. It took me sometime to realize this – despite the instruction in the Book of the Scott. Hence my first two purchases from the club spares scheme were 2-speed kick start return springs. I repaired it the first time and then immediately broke it again !! Often I find that the dab works best from the side of the bike facing backwards – there is less chance of over applying the lever.
Keep going Mark it will be worth it – there is nothing else like a 2-speeder at full Yowl.
lewis onionsBailer twine, brute force and a helping hand. See my post 25th January 2021 in “Work in Progress” – Photo Wall Section.
lewis onionsHi Wilfred – I’ve never seen a veteran Scott with the silencer you refer to but the 1913 model owned by Birmingham City Council (KT 4963) which used to be in the Science Museum in Birmingham does have one, I think. It’s been in long term storage for some time and no doubt is now seized solid!
Anyhow, if you refer to the 1914 Parts Catalogue in the Members Resources – Document Archive you will see a rather good illustration. You can see that it fits over the end of the exhaust pipe which has perforations at its end where the silencer fits . You might be able to work out the dimensions of the silencer by reference to the other items on the page – the diameter of the pipe should give you an idea of the size.
Regards, Lewis
lewis onionsAnd the John Underhill Memorial Run will pass right by the campsite !
lewis onionsThanks for all the positive feedback. If the bike is to be considered a fake then what would the Kendal Scotts created by Kit Parker be, for example? Virtually all the parts will be Scott original or re-manufactured to Scott design save for a few parts such as the saddle which will be the sort of after-market parts available in the early 1920s. There will be no deception or woven back story to suggest that it competed in the 1922 Latvian International TT !
Anyhow work is well underway. The frame has been blasted and proves to be in good condition save for the end of the seat tube which required a new end grafting on as shown in the photographs. New seat stays have also been fabricated to replace the unusable rear subframe.
The new rear sprocket, hub and spindle all needed a great deal of fettling to fit correctly in the frame, taking into account the very small clearances between the kick-start and the line of the rear chain. The spindle didn’t hold the hub central in the frame initially and the back of the sprocket required milling to provide for sufficient clearance for the wheel spokes. Then great care was necessary to align the rear sprocket with the 2-speed gear and the gear with the drive sprockets either side of the flywheel.
I obtained a couple of the later, more substantial, frame brackets for the 2-speed gear from Mike Field a couple of years ago. I have had two experiences with the smaller earlier brackets shearing – once on a return trip on the Coventry – Brighton Run and another on (thankfully) the last day of the Kingdom of Mourne Weekend in 2020. On both occasions I could be considered to have been at fault by trying a bit of engine braking, but the larger type brackets must be an improvement and might avoid another trip in the recovery van.
Whilst this is all going on other outstanding issues are being addressed such as the fork stem (a new one is on order form Roger Moss following his advert in Yowl recently), wheels (rims and tyres have been sourced) and the engine (??).
More to follow as things develop.

lewis onionsWell I couldn’t really pass up the challenge, especially watching the 1926 wreck Ted has referred to passing through Ebay at such a price – and without a 2 Speed Gear too. Whoever takes on the Ebay machine will have some challenge sourcing one of those !
Anyhow, as the ever resourceful and capable Dave W will be doing most of the work I can settle back into my usual role of “Co-ordinator” – a bit like a producer in the movies.
Some decisions have been made based on the availability and serviceability of the parts we have. Firstly, the rear subframe of the Bonhams bike is u/s and suitable only as a pattern. Whilst re-tubing might be an option, the best option seems to be to dispense with it and replace the subframe with a new one made to the Squirrel pattern – i.e. without any carrier. This will make the bike a little sportier and fits in with the overall objective to create a “special” of the sort that might have been produced for competition in the early 1920s.
The second decision is the engine. By far the easiest option is to stick with the 532 cc engine and add the relined barrels to the bottom of the Bonham’s engine. The +60 Hepolite pistons can be turned down to fit at the standard bore. This might not be as in-keeping with a sports bike as the 486 cc Squirrel engine might have been, but there was at least one Standard Scott as a private entry in the 1921 TT.
As I have already hinted, I will most likely retain the stirrup front brake, although the 1921 and 1922 works entries in the TT both had very small drum brakes. I have been pointed in the direction of a very small front brake and hub which might be suitable but it is unlikely to be available until the summer.
So, to sum up the bike will be an early 1920’s race replica or “evocation”, although I think an evocation in the car world refers to an entirely new vehicle made to look like an old one. It will not be a copy of any particular bike but will draw on individual characteristics of the several TT bikes in the 1921/22 period. Some of the TT bikes’ features are a bit beyond budget and practicality – such as the twin 2 Speed gear arrangement of the 1921 bikes and the twin-spark ignition system used in 1922. However, we can pick and choose the practical and perhaps achieve something special by selecting some of the best. For example, the 1922 works TT bikes had purple painted tanks with the twin parallel silver bands, like those used on the 1912 models and plenty of plating – but deciding on the paint and finish is a long way off yet !
Attached is a photo of Jimmy Simpson on a 1922 works TT bike which conveys the overall idea.
lewis onionsHere’s a picture of the bike and its owners taken in June 1951. On the bike are John Batchelor and Audrey Batchelor (nee, Taylor)
They lived in Witton, Birmingham until 1956 when they moved to Pheasey, Great Bar, Birmingham.
Their grandson Adam Greenfield is trying to trace the bike.
lewis onionsHello Glyn . I have a large commercial scanner at work so send them to me and I will scan, up load them and then return them to you.
Cheers
Lewis
lewis onionsHi Richard
The Ken Lack rod is 8.5 inches and the original 9 inches. KL has 1 1/4 inch threaded adjustment and the other 1 1/2.
Both are 1/4 inch diameter rod.
