Snake inners

[Mowerman]

I am assembling a Prangster and when fitting the threaded adapters into the snake inners Ican only get them in about 5 or 6 threads.Even tried hot water to ease the job.The inners are hard, ribbed ,clear plastic.

   Is this enough ?

   How do you do it?

Using snakes something like yours I carefully smothed the rib parts down until i had a better fit. A drop of silicone polish on the threads may ease insertion into the clevis. Worked for me.

Thanks Flytillbroke but these snakes need the threaded bit screwed inside the snake inner.

A short length (30mm) of 2mm studding is supplied. This then takes the clevis.

Mowerman, lack of sufficient grip is the usual issue. Try wrapping a couple of turns of masking tape round the threaded insert. You should then be able to hold the threaded insert with a small pair of pliers with enough grip to wind them into the inner as far as you like, without damaging the thread. (Use a piece of masking tape on the inner too, if you find that slipping in yoiur fingers whilst you're twisting the insert into it)

I've found that gripping the threaded part with a 3 jaw dremel chuck and turning it by hand works well with the Sullivan ones - with no damage to the threads.

I grip the thread with pointy pliers in a place where the thread isn't used by the clevis, and 'lubricate' the thread which goes into the inner with mk1 lubricant (i.e. spit on it).

As you turn the thread to the point when you can't hold the inner any more give it a good tug -if it doesn't come out you should be OK.

I think the spit is the important bit because it is quite a good lubricant and then the metal rusts inside the inner, causing it to expand slightly. All I can say is it is one heck of a job to get the thread out at a later date, you have to cut the plastic off.....

screw the threaded insert in to a clevis with a locknut then you can wind it in easily to the snake you can use a small screwdriver in the clevis for more leverage if you need to

protect the thread with a bit of the rubber grip tube. Then place into a drill chuck. tighten . Hold snake with pliers and drill in slowly. its how I have done it before. not to say it's correct though!

[Peter Miller]

I thread a clevis onto the threaded part and insert a scalpel handle and screw the clevis down until it grips the handle.

 

I hold the snake inner in a pair of pliers and wind the threaded bit in for about a 1/4 inch.

[Mowerman]

A Big thankyou to all who replied.

I am now happy to continue the assembly

This job is made a lot easier if you use the correct tool for the job.

 

Sullivan provide a threaded knurled aluminium barrel that is threaded onto the threaded insert and then wound into the snake inner.

 

Should be available from any decent model shop that carries Gold-n-Rods.

 

Quicker to do than to type it out.

I must admit I stick the threaded part in my cordless drill and let the drill do the work.. Works a treat.
