Just thinking about this, how does the half link mesh with the sprockets? Surely they are designed to work with chains with uniform size links.  

No change, rolers are all still same width.

Some competition pushbike chains are 100% half links....every link thereof.

The top example `two-stroke` shows is the strongest solution(as half link is integral part of a complete chain), because the half link is already secured with peened-over pin. Just add traditional split link....or with the right kit you can do away with a split link and have a continuous chain, by using soft-headed pins and peening over.

With the bottom example it can be fitted with a full split link in addition(certainly not advised to have two split links,especially together!), or will need a roller removing from your chain to expose the two opposing side plates, to slot the half link wasted section  in, then pin fitting & peening over. If you`ve got the correct kit then it will be just as strong as the above one that comes already fitted to the chain....plus again, you can fit pins with soft heads and peen over for a continuous chain....therefore,no split links, no weakest link!

As it is a Reynolds chain it is most likely to be the correct imperial size for your bike.

So to do the job right I need a tool to remove and insert links. Plus I need to find a supplier for a half link, which may not be that easy.

Thanks for all your help

I have always found the chain man very helpful when purchasing chains and spare links. he is at : 

the-chain-man.co.uk/

Visit his site, he is very helpful and happy to discuss your requirements.

Years ago we quite often fitted half links to worn out chains to make them last a bit longer and keep us on the move.

I seem to have twisted the sliding part of my split link. Will i need to buy a new split link or can the sliding part be purchased separately? I should add i dont know the specification of the chain as it was on the bike when k bought it. Alan

If that is the only problem just twist it back. The essential part of the issue is that the clip closes securely around the grooves in the links. If it is loose, replace.

Thanks. "The Chain Man" will be my first port of call, he sorted me out with a clip for my split link very promptly so hopefully he will have a half link. I was looking at the splitter-rivetting kits on ebay only cost about ten pounds. I assume they will work for my old renolds chain.

Watch the quality, some are so nasty(monkey metal), they`ll even break when used on pushbike chains.

Back to mudguard. Rather than taking the rear wheel on and off multiple times when adjusting the mudguard it occurred to me that I might be able to get a spanner between the tyre and down tube to hold the bolt head captive and then get a spanner on the nut inside the box section and tighten there which would allow me to adjust the mudguard with the wheel in situ. 

Has anyone else tried this approach? It might be there just isnt enough room inside the box section to move the spanner enough.

Morning,DO NOT buy a cheap chain splitter they will not work ,I speak from experience.If you buy a good quality one you may still need to grind off the rivet head first depending on the chain size.Good luck

Back to the rear mudguard! I manged to purchase an old used one which is pretty sound so at least I will know now if the wheel clearance problems I had are due to the non OEM (Indian) guard that was fitted. 

Unfortunately it doesnt have any brackets but a kind local member has offered to help me make some. 

What Im interested to know is how the brackets were held in place on the original item. Were they bolted or riveted to the guard?

My Indian copy seems to uses bolts with round heads for the top bracket and for the rear bracket it appears to be riveted in two places with a bolt in the middle hole which also secures the rear plate.20190506_132824_resized.jpg20190506_132806_resized.jpg20190506_132516_resized.jpg a little unusual.

As you can see there are a lot of holes in my rear guard. Unfortunately the ones for the luggage rack aren't in the right place!

The guard is from a D1 rigid and the luggage rack is right for the year of my frame (1950) -its one without any cross members, so it should fit.

Im now intrigued to know exactly what was fitted to this guard, could it have been a double seat I wonder? Interesting to note that where the rack is supposed to go there is a single hole at one end and three at the other. Also seem to be some small holes in the side of the guard. 

Does anyone have any thoughts on what could have been fitted on it?

 

Thanks

Having struggled for 12 months I now realise that my rear frame is bent. The gap between the rear wheel dropouts is an inch wider than the hub and the dropout on the brake side is pointing slightly upwards, so when the spindle is in place the wheel leans over very slightly to one side. 

The plan is to bend the frame back into place, as I am sure many Bantam owners have done in the past. The problem is I dont have any dimensions or measurements. Without these its a bit hit and miss.

I was hoping a member might know if any engineering drawings of the D1 Rigid frame survived, or if anyone has at least rudimentary measurements.

 

Thanks
