Scottoiler Feed Pipes

Model shops (proper ones).

I've fitted Alan Crowder's old Scottoiler to my Armstrong - thanks to
Lozzo for the missing bits.

Unfortunately I can't follow his advice of having the feed nib at 6
o'clock as the torque arm bracketry is bang in the way. With a bit more
supply pipe I might be able to get it to 4 o'clock.

There is also another problem. On the sprocket there are a number of
socket cap screws which rotate with the sprocket. Unfortunately they
clip the feed nib. I have bent the nib so they miss the screws but I'm
not 100% it'll stay that way.

I'm after some small bore pipe, aluminium or copper, O/D 2mm I/D 1mm? to
bend and form a better, more permanent feed nib.

Any ideas where to get it from?

 

Have you tried fixing the bracket to the torque arm rather than the
spindle?

Take the screws out, countersink the holes in the sprocket and use
countersunk socket screws. Make sure you countersink them to the right
angle rather than just using the end of a larger drill because the
angle is different.

Use some steel brake line and adjust the end of it with a ball pein
hammer.

 

B&Q stock stuff like that

 

I need to get some more feed pipe as it's just a bit too short - there's
a place near me that sells clear pvc pipe for fish tanks etc. Then I'll
have a go at making up a new torque arm bracket with a bit of meccano
strip.

What does the metal rod in the feed pipe do? Can it be anywhere in the
feed pipe run?

Countersunk screws have a larger 'footprint' than socket cap so I think
clearance from the brake hub will be a problem (see picture).

O/D may be a bit much but I'll give it a go.

 

That is, making a feed nib bracket with meccano not a torque arm
bracket...

 

They do? What's it used for?

 

It's there to stiffen the feed pipe and allow you to bend it to
shape. Also, the pipe and dispenser tip should be bent round in a
curve to clear the heads of the socket bolts, and deliver the oil to
the surface of the sprocket adjacent to the chain - not dripping onto
the chain itself. Have you looked at the instructions and stuff on
the Scottoiler website?

 

Ah, I thought it was a restrictor device.

That's how I have it, except it's at 9 o'clock. I wasn't that convinced
about it keeping its shape.

Instructions, INSTRUCTIONS!

 

For women and gay men. Don't let it worry you.

 

Looking at your photo of the current installation, I'd be tempted to
warm the little black pipe up a bit and put more of a hockey stick
curve in the end of it, so the majority of it goes straight back,
clearing the bolts, and then it bends in towards the sprocket. Hot
water or a lighter should suffice.

 

They have a sort of hobby section with lengths of tubing, bar, flat,
square section etc in various materials.

I'll have a look around the garage tomorrow afternoon and see what
I've got.

 

Poke a length of thin steel wire up the delivery tube and bend it to
suit. The bend will keep it in place and enable you the bend the
delivery tube to the point you want. If the wire is thin enough it wont
restrict the flow and you don't need the bit of black tubing stuck in
the end.

 

This is what I'd do, but I'd just bend the black delivery pipe after
heating it up to miss the cap head screws. You could probably do away
with the holding bracket and just cable tie the pipe directly to the
torque arm if you took that route.

I don't point my delivery pipe at the sprocket as they tend to get
deformed and blocked with shite, which means they then stop delivering
oil to the chain. I have the oil drip directly onto the chain, in the
way recommended by Scottoiler.

The wire in the plastic pipe is there to allow the pipe to be bent
whilst holding it's internal shape and also acts as a flow restrictor.

That's not what Scottoiler say.

That would be a ecumenical matter.

When I had one fitted I used this:

to cable tie the tube to and bent it to just the right place
on the sprocket.

Simo has one of those already:
