Title: Head steady #3
Post by: Carolyn on October 11, 2017, 16:59
Had a chat with MikeK at the weekend, on the subject of engine vibration, mounts and steadies.

I decided that the head steady I was using was too harsh at idle, although it's really good under load.  So I decided to try one something like Bernie's.  Fiddly to get it mounted properly and to get it adjusted in the middle of its somewhat short stroke.

Very pleased with the result.  Big improvement at idle and works well under load.

Surprised you had any issues at idle. Yours was more padded than mine.

Looks good though.

I've always avoided a "solid" solution like Bernie's because of the vibrations, which are very noticeable in Bernie's. It's very "race car".

A mix of both would be choice. One rubber stopper like mine at the body end would solve that.

Any part numbers for that shock?

It's only a friction damper.  No hydraulics, so I was dubious.

Nice. Does the job. It's on the list after injector cleaning  s:) :) s:)

I've 'tigersealed' my engine mounts. Front, rear and  top left.  That might make the difference.

That looks good, nice solution!

That's a neat solution, any chance of a pic of the chassis bracket, I take it that you had to fabricate that?

Quote from: "Mikeymead"That's a neat solution, any chance of a pic of the chassis bracket, I take it that you had to fabricate that?

It's just a piece of ally angle.  70 mm x 40 mm and 30 mm wide, 3 mm thick.  Two 6.2 mm holes for bolting to the chassis and one 10.2 mm hole for the steady.  I had to shave a bit off the corner of the cam cover with a file (if you look carefully in the top photo, you'll see that) in order to get the rose joint to clear.  Sorting out the right nuts and bolts took a while, even though we had them in stock. Then there are a couple of spacers to allow the rose joints to work and to get it all to line up happily.  About two hours of trial and error to get it right.

I'll be taking it off to tidy up the corners over the weekend, so I'll take some pics then.

Do they work equally well in tension & compression? Or only one way? I need something for the Datsun rather than the 2

It would seem so.  As I said, it's only a friction damper, and you have to be careful to have it in the middle of its stroke when you mount it.  How well it will work on a heavier engine would depend on how much the engine is moving on its mounts, I suppose.

Thanks Carolyn. Might give one a go.
