Can anyone make me this part (handbrake barrel)?

Morning gents

Is anyone with the big tools I don't have (lathe, mill etc) up for making me one of these:

https://caterhamparts.co.uk/handbrake/1435-handbrake-barrel.html?search_query=Handbrake&results=30

It's the handbrake barrel for the underdash handbrake on a Caterham. It's a bit weird in that it acts on the cable outer rather than inner. It's not straightforward to relocate the handbrake to a conventional position as the trans tunnel on a Caterham isn't filled with box section etc so not meaty enough.


I would buy one but they are out of stock and have been for a while.

I can work out the dimensions using the ID of the hole in the handbrake lever which I do have (fortunately as also out of stock permanently it seems!) The length I guess is less critical but could be worked out from the photo using the ratio.

If you can get the correct diameter (if thats important) bar, then a pillar drill a saw and a file will get you there also, takes a bit longer but do-able.

Good point. Need to get my pillar drill back from a mate first though!

I'm poorly equipped to fab stuff up at the moment as have very little space in current tiny garage.

Dimensions and what material would help no end. I guess due to bending forces, steel ?

I guess it's 50 to 70mm long and I think steel would be a good idea.

I will try and draw something up.

I think I've got access to a 3d printer so just for fun may try and do it in that just to test it fits.i suspect it would break after not very long in actual use.

I was struggling before with the image library thing and a bit busy but here is where it fits in to give an idea...

Looks like an extremely easy part to make,

take a long shanked bolt of the right size, cut the thread off, and hacksaw a slot to the desired spot

you could even leave the bolt head on, to stop the part dropping out

Thats was probably spelt wrong, or had some grammer, that the "grammer police have to have a moan at

Looking at it I would be surprised if it's more than 30mm long and I guess the cable stops the pin dropping through.

Have I missed it or are the dimensions missing from this thread?

Sorry gents I am hopefully getting hold of a used part from a fellow Caterham owner who relocated theirs to the tunnel.

If that all falls through them dims and a drawing will appear.
