Any good for a sprung saddle?

I started on the Hand change lever last night.

This was the basic idea.....

But it's obvious that there would not be enough clearance for the arc of movement if I did not modify the design slightly.


So I introduced a slight dog leg to give a running clearance on the cover.

I used a felt tip pen to black up the plate and scribed the shape with dividers.
Then I bandsawed out a parallel section.




Then I milled it to the line, so as to give me something parallel to hold in the vice.

I drilled out the pivot hole (which will eventually become a square).....


Then continued drilling progressively smaller holes along the centreline of the lever.


I made a bung in the lathe....

And turned this to suit the gearbox spotface.

This will be used as a gauge, when I form the true radius of the lever, to ensure that it does not foul the cover.

Once I'd established the true clearance radius of the lever, I turned down the smaller diameter to suit my drilled hole in the lever.

I'll leave this in place when I profile the radius on the linisher.


That's as far as I got. 1.5 hours so far.

Gonna shy away from that as there's too many about.
What I'm looking for, is four brass balls, about 7/8 to 1 inch diameter.
And yes, I've checked the local monkeys.
I'll thread the balls over a stud in the top of the lever, leaving the last one tapped blind.
Anyone got any brass balls?

I think I've got a sprung saddle off a BSA M20 (I know , stop laughing at the back ) lurking in the shed 'somewhere'
It might be useful to cut the top off to make a mould to lay up your own and then shove the little shock underneath

You're welcome to it, if you want it.

I've already marked out a seat pan on a nice bit of 3mm stainless. I can't cut it out yet, as it was part of a machine I'm building. I've just got to persuade the customer that it's not required on the machine build.

There's not many true Ironmongers left to look at.
I can get them off Ebay in the States, but I'll poke around a bit more here first.
I'm calling in to Kempton Park (Autojumble) on the way up to Sproutfest, just in case there's a cheap girder available.

Cheers Ian. Whatever I use must be able to be tapped 6 or 8mm through. I thought about looking in antique shops, but I'm much too young for that.

I think this looks classic but you could probably knock something like this up yourself.

OK, so seeing as I didn't have to take my annual bath for Sproutfest tonight, I consoled myself by staying on at work to do some more to the Gear change lever.
This is how it looked the other night.


Before I could shape it, I needed to mill a slot that will act as the clamp, while I still had something to hold in the vice.The centreline between the two holes is not square to the vice, so it had to be rotated.


With that done, I could bandsaw out the profile.

My bandsaw is a bit knackered, so you can't run to the line accurately, but it's good enough for roughing out.

Once I'd cut it out, I put it back in the mill and machined the straight sections to the lines that I'd scribed.


I also milled the end square.

Once that was done, I started to linish the internal radius.

I've still got some more linishing to do, then I'll drill the cross hole for the clamp and drill and tap the end.

3 Hours total so far.

All that bling and it's not even a FXTWATAIL.

Just some old Triumph


Mick - this annual bath thing. What does it entail?.
