Hello Guys..

I see...Said the blind man. I understand now. Internal diameters of the 'A'frame bush mountings. Big ones and small ones.

Got it now... Hic'... Sorry Brian...Your question now appears answered though.

I broke a flamming big Vice trying to push out one of the larger inner bushes. Bugger! Had to go and retrieve my spare which is now sat on my bench. Set up my hydraulic press this morning and pressed out all the bushes on 4 frames in jig time. Now why did I not do that to start with.... Doh!! Dingbat!

Cheers guys.

Paddy,

John knew exactly what I was asking for - it was just his usual stiring engineering humour getting the better of him.

Yep!! Guilty as charged !!

I was just plain dopey! Didnt think the thing thro' Sorry...

John had it answered anyway.... I'm just going back to sleep!

Hi Guys,
Finished the 'project'. Not too expensive or time consuming really. Pic's below will let you see how I ended up doing it. Following on from the previous set. The only thing I could not live with was just plain butt welds via the mig. I ended up with a re-enforcing 'tube' (I split it to allow a weld along the length attaching it to the tube below) I also ended up with a 'plug weld' on the end of each piece down into the tube below. I think they are well strong enough now.

See what you think. I will be keeping a close eye on them for a while never the less & I will advise of any issues found.

For a starting position I 'centered' the adjusters.Turning them 'till there was freeplay. IE the tube was neither in tension or compression, then I wound on (extending the length) 1 turn on the turnbuckle. This, I estimated would push past the original setting and also provide a small amount of toe in more than original. Gotta start somewhere. I will line up with more care when I have the car re assembled. I'm then taking it for full setup / alignment check.

Here are the final pic's. These A frames going back down to Geoff (thecyclist!) who kindly sent me 4 off for trial purposed. 2 off which were usable. You will have these back soon Geoff.. Thanks for your help..

Hi All

Now I have done my A-frames too.
Thanks for the turnbuckles Alex.

I made an smaller diameter tube to go into the A-frames where I welded it back together to reinforce the joint. Also the threaded bushing was TIG welded around the edge to stop water from getting in that way.
It took some double checking before cutting the A-frames and also a lot of additional measurements under ways, but I pleased with the end result and they adjust nice and easy.

Using the M12 thread it should adjust the toe about 2° for one full turn of the turnbuckle.

So now it out with the old bushes and of to the sandblaster before painting.

Thanks to everybody for the help on the way.

Lookin good Jas! Just need to set it up now. Easy!

Nice work gentlemen.

This information (AC 43-13) on welding, splicing, rosette spacing, etc. of aircraft tubing might be of interest. Scroll down to around page 4-68.

Great bit of info' that. Thanks.... I hesitate to call you spanner but I have no choice, sorry.

Very useful in many respects and will help anyone else doing a similar job. (Pay attention you lot!)

Thanks from us all...

Alex B...

Coming to this a bit late but might be of use to others in the future. Did you try heating the "stuck area" with a torch and then trying to move the turnbuckle? Usually works wonders.

I am a Mech Eng and have always believed that if you don't have a big enough hammer, it's time to get the torch out.

I didn't Pete. But boy was it stuck. When I cut it out I cut thru the joint and freed the turnbuckle off just to have a look-see. It would not have freed off I don't think. (I too am a mech eng)

The Mk 2 method is still the way to go as described above. You really need to remove some pipe and replace with the modified parts.

Anyone need some turnbuckles to do this job? I still have a few pairs left with the lock nuts. Just a small cost + postage to you guys.
