Cheers for the post Pete Nice use of copy and paste http://coolercasesuk.co.uk/showthread.php?t=1211 but cheers anyway.
Perfectly allowed and there nothing of use on here showing anyone how or what the parts are so i though it'd be a good idea to show it off.

Also you going to respond to any of my e-mails the Danny or sit high and proud?

Its the threads in the crank arm that are gone and need re-tapping. But i dont kknow what size tap and coil i need. plus its oppisite threads.
9/16 inch x 20 tpi - Pedal threads- common three piece cranks
How ever the threads on pedals are back to front threads. Could get a steel insert made, have them lathe the threads on to it. Screw it to the pedal then into the the crank with some thread lock.
Belive Edd Pots is the man here for enginering.
I can ask some local guys what they can do for you too but i'm not sure how much it'll cost.

Wont the coil come out the other side? Because i want to do some cranks I've got. here is a link to the topic linky linky Could you help me out? As you seem to know what your doing. thanks paul.
Hi Paul,
So you have a set of Echo CNC'd cranks, right hand thread for the pedal has stripped. Is that the threa in the crank or the pedal repaceable insert gone on the threads for the the pedal?
The coil doesn't move once fitted and the tang removed.

Description
- Need something to tensioner your chain that's cheap, durable, and unobtrusive? Look no further!
- 2-point fixing (mech hanger and dropout - for both Hope Pro2 and standrd QR hubs) ensures the tensioner stays tight.
- Extra wide machined Polyurethane jockey wheel running on sealed cartridge bearings is durable and quiet, and fits all chains.
- CNC Machined aluminium alloy main arm curved in towards the spokes, keeping it out of the way.
- Steel fittings to ensure they dont get rounded off!
- Super slim design keeps it out of harm's way.
- Can be set for up or down tension.
- Not compatible with Chris King Fun Bolts (without heavy modification).
- Weight: 102g including all fixtures and fittings.

Here is a guide for you all should that beloved frame strip a thread.
Please not these photos are not of a bike but a pure sliver base which had the same issue. The manner to the work is exactly the same.
Helicoil has many applications and is a great way to replace a stripped thread.
Stripping the thread is a common occurrence with all small and fine threads as usually they have a stainless steel bolts tightening down into a aluminum base which is a very soft metal so a turn to much can easily strip the thread from the softer metal - all is not lost
There are a couple of methods that could be used and my first thought was to simply re-drill and tap the offending hole but this would then have left the dilemma of finding a new larger stainless steel Hex bolt so decided to try using a Helicoil which essentially is oversize drilling and tapping the hole then using a Helicoil to plug the hole to the same size as it were previously.
Closer inspection you can see clearly the thread was in fact stripped good and proper
So first of all the hole was drilled out using a 4.1mm drill
So the hole was oversized like this
Then using a M4x.7 Tap, re-tapped the hole (2 turns in and 1 turn back to get rid of swarf)
So your left with a nice rethreaded hole like this...
This is a close up of the Helicoil which will be used to bring the hole back to the correct size.
As you can see its basically a small spring with a dog leg on the end called a "tang" which is needed to screw the thing in place.
A special tool is used to compress the spring so that it can be screwed into the hole - the idea is that once in the hole the helicoil will de-compress out over and attach itself to the threaded hole.
To start off with the small Helicoil is screwed loosely onto the threaded shaft of the tool like so...
Then the shaft is inserted into the body and screwed in so it compresses and just starts to protrude out the end of the tool which also has a threaded end - the Helicoil has no alternative but to compress in over
so the end of the tool looks like this...
That end is now placed firmly over the threaded hole on the block base and while keeping hold of the body of the tool, the shaft is screwed out which forces the Helicoil into the base
and from the other side of the base you can just begin to see the Helicoil coming into place
Once the Helicoil is flush with the base and the "tang" is just protruding the shaft of the tool can be screwed back out leaving the Helicoil in place
......and from the other side
As you can see the existing bolt now fits back into the hole perfectly
Using the tang removal tool which is essentially high tensile steel bar which fits the hole, it can be placed on a sturdy bench and hit with a hammer which removes the tang like so - leaving the hole flush to rest of the base with a perfect re threaded hole to accept the hex bolt.
Just like new

no im running it with down tension thats the weird thing it shouldnt come loose as when you pedal it the top of the chain that goes tight the bottom goes slack, im using the bolts that are supplied with the tensioner
ill try and get some pictures if i dont manage to fix it
Silly idea here but one that might prove an issues with your chain. Remove the Onza tensioner, lift the back wheel off the flor and then pedal the cranks round. Look at the chain and see if it has any stiff links etc. It might be your chain has a twsit or is worn.
You mounting the locking point to the mech hanger? This is what stops it moving up or down and keeps the tension there.

right ive got my onza single speed tensioner but it keeps moving, as i pedal and the chain goes tight it pull the tensioner right up so when theres no pressure on the pedals the chain flaps about.
its on an adamant a1 frame the rear sprockets 14t, the chain is a khe collapse chain and the mech hanger is also new so not bent etc.
when i set it up i set the tension so their is still abit of play when theres no pressure but so it just starts to pull when their is i made sure the qr was super tight and also the bolt that screws into the mech hanger.
the tensioner is here: onza tensioner
any body got any ideas?
So your running it with up tension. Ether a wrong bolt is being used so it moves up and there is no tension there. Can you change it to run down tension and shorten your chain any more? Maybe if you get some photos to see it

Skype is a bit odd. I recently bought the Tesco version.
Tesco FF128 Cordless USB Internet Phone (one I have)
It's currently £30 reduced from £40 and came with £5 free credit.
Works really well, already using it more than many mobile and landline at home. Best bit is that it's totaly free to any Tesco user and soon Skype and other VOIP systems.
It's only any true use over a BT line if you have a cable DSL IP provider such as Virgin Media (Telly West) as you don't need a phone line for there internet
