How to:Handbrake trim ring
How I made my Sierra handbrake trim.
![](/galpreviews/IMG_0405_1.jpg) ![Handbrake](/gallery/IMG_0405_1.jpg) Handbrake
First the former, I used MDF it measures 210 x 80. The aluminium overlaps the former by 7mm in all directions and is 1.2mm thick (use thinner if
that’s what you have).

The reverse side is roughed up to provide a key for the adhesive when fitting the gaiter.

The aluminium is temporarily fixed to the former with a couple of rivets. Once riveted hold it in a vice. Use a soft headed hammer or mallet bend the
edges over the former. Take your time doing this, a bit at a time working around the edges gradually. Once done it should look something like this.
I used 48mm diameter circles to mark out the cut-out as drawing.

After cut-out is done the gaiter is fixed with contact adhesive.

All that remains is to fix it to the tunnel. I used m4 button head bolts and rivnuts. The leather gaiter is off fleabay and cost about a tenner.

The same idea can be used for the gear stick gaiter too.

That's a nice guide thanks!
I've hit a bit of pause on my build and to get myself going again without spending money on bigger things I might have a crack at my tranny
tunnel.
Did you hand cut the former with a jigsaw as that's all I've got for cutting mdf.

Yes, just used a jigsaw. These penny projects help the build along when funds are low, good for motivation.

Do you have a link for the gater, found a load when I searched on ebay but wasn't sure which one you used.
Also what Lshape ali section do you use for the edges of the tranny tunnel?
Cheers

This was the one I got.

A bit more money from when I bought mine, the quality is good though. I did specify it was to fit a Sierra handbrake with a after-market Richbrook
handle which was no problem and no extra charge.
The L shape ali was just some 30 x 30 angle aluminium which I rounded the corner off with a router. Although it can be obtained already rounded from
some suppliers.

It's a very good way to make "factory" looking parts.
I used two bits of hardwood floorboards cut to the same shape to make these panels for a small brake air scoop. The aluminium is clamped between
them, and then you beat the aluminium to the upper or lower side depending whether you want a left or right handed part - and they'll both be
the same size :-

Hi there,
This looks excellent - I'd like to do the same thing with my Tiger.
Where did you get the gear lever gaiter from? It looks properly neat...
Thanks,
Pete
