appreciate the positive feedback, wish I had more time to do videos it was a fun

Looks like Brompton made it that way so only a dealer could do that job, looks easy but the cost of the reamer makes it uneconomical.

I agree about the official Reamer but most workshops have a set of reamers which could be used

Thanks, we’ll done video. I may try using a regular shorter industrial 32mm reamer and attach it to a home made extension to keep it aligned. What size diameter is the mandrel?

Eyeballing it I would say 31mm . It appears to be a 32mm tube that has been turned down to 31mm for most of its length. I will update when I find my calipers !

Do you know the diameter of the mandrel? Assuming it’s not tapered any tube of the same diameter could be used?

Do you know where I can buy the reamer tool in the uk? A web search didn’t show anything.

the original manufacturer is www.metalbor.com (its a Trubor brand) , or any Brompton dealer can order for you QSTSLV-REAMKIT ) or I suspect you can get any 32mm reamer that is long enough to fit through the bottom tube

Can you put the website where you bought the complete tool? The reamer and the piece that you turn by hand. I can not find it anywhere. Thank you.

I bought it from www.rjmstar.com in Dubai (QSTSLV-REAMKIT)

is there a way to replace the sleeve without having to use the special tool ?

Brompton don't seem to offer pre-reamed sleeves any more. I did see some for sale on ebay, typically from Hong Kong sellers. I have several Bromptons and am experimenting with different seatposts, so decided to buy the special tool ('reamer') and some spare sleeves, that way I can always have a good fit. Many years back I damaged a frame because I overtightened the clamp rather than replace the sleeve, had to replace the frame !

At the end of the video you mention that you will be doing more vids, what are you planning to cover ?

I am building Brompton e-bikes and will cover the process. My main project is to create an e-Brompton Air , an electric Brompton that can travel on an aircraft, it needs to be less than 23kg in a case and the batteries acceptable for cabin. Probably I will use power tool batteries. The second project is to create a 50km/hr e-Brompton using a home made 52v battery pack.
