Hi all - I am curious as to the purpose of the device on the timing side (right) crankcase / timing cover and the line that runs to it from the fuel tank . I am currently building a 1/9th scale model of a 1933 Blue Star 350 . I initially thought this to be an oil pump but now that I see the line to the fuel tank I am uncertain.
There appears to be a tap lever on top . Did this allow dilution of crankcase oil for low temperatures?
Thanks in advance for enlightening me.
It's the pipe that feeds the oil pressure guage in the tank panel. I wouldn't take any notice of the photo you posted though as this shows a lash-up with a bit of rubber pipe. The original fitting was a solid copper tube with a banjo fitting at the timing cover end. The pipe neatly follows the timing chest to the frame downtubes where is ascends to the headstock before deviating toward the tank.
Hope that's clear, David
Thanks David for the quick response. It now makes sense. I see the bugs rubber tube in the photo- it was the first I found . The kit supplies appropriate size solder to make up these lines .
addendum: is the devise at the top which I thought may be a tap handle a tell tale flag for oil pressure?
The "tap" is the oil regulator.
Thank you yet again David . Here are a couple of pics of the project so far - also a link to my build log is posted in my paint details thread .
Very impressive level of detail in that model. I wish some of those components were still available at full size!
Thanks for the kind words and prompt responses . These are indeed very detailed and labor intensive.
Yet another question if I may be so bold . Where would the voltage regulator be located ? I am thinking in one of the panniers? I have seen photos of some with the regulator mounted on the mudguard behind the saddle but as this model will have a pillion it must be elsewhere. I am getting ready to start wiring the model and I can fudge it but it would be nice to get it right.
Thanks you again for your help .
Cheers- Richard
Beautiful model!
1936 and earlier Lucas systems used a 3 brush dynamo so a voltage regulator wasn't necessary.
Many people upgraded to the later 2 brush dynamo as the earlier system became obssolete.and fitted a regulator in a suitable place, often under the seat.
Early dynamos were held together by 3 3BA screws at either end. Later 2 brush dynamos used 2 long 2BA bolts.
Thanks for the quick response. I am somewhat embarrassed by my own question now as I should have known this . If the two bolts vs three screws shows on the end of the dynamo by the triangular drive cover then the dynamo supplied with the kit is the later type . It is identical to the later Magdyno on my ES2 Norton. I will proceed as if there is no regulator-Thanks again

I just have to say that's an amazing model, that is truely excellent work. Is the chain a real working chain?
All the best,
Glenn
Hi Glenn - Thank you for the kind words and my apologies for the late response. The chain does indeed work - it is built up of white metal rollers and photo etch links. The wheels do not rotate however. In this same forum I have an earlier post " 1933 Blue Star Paint questions " with a link to a scale modeling site where you can follow the build process if interested. The model is now nearly completed and I will post pics here in a few days.
Cheers- Richard
