Something tells me you screenshoted the photo and then used an electronic zoom? Maybe you would be better off using technology that existed when the was new?

Like maybe take a photo of my computor screen with a Polaroid SX70 camera?
I did try blowing up the photos but with my browser and just when things start getting big enough to work out what they are, they become so pixellated it does not help, which I suspect is how you want it to be.

David, just thinking outside the box, can the chrome plating process be reversed? What I mean is if it is a positive charged consumable transferred to a negative charged product, what happens if the charge is reversed in a chrome plating tank?

Pretty sure the aluminium would go into solution faster, or at least along with, the chrome. They do use reverse electroplating to remove the chrome from steel parts.
The chrome comes off pretty easily with abrasive power tools but that is only applicable on the easy-to-get-to bits and there are lots of places on those covers that are not able to be reached with a 100mm disc. I haven't tried dry blasting yet, holding out in case someone knows of something more likely to preserve the casting detail on the covers

I love this time of year because I get to do motorbike stuff in the workshop. Tidying up this tank is one of the things currently on the go and it's almost at the pretty stage.
I had a good laugh with the paint mixing person at the paint shop when I saw what she had named my paint colour

So it seems that my photos have been blown up and heavily scrutinised, sorry for the frustration, it is quite simple when you know! Here are the photos again to save you flicking back:

Also, I thought I should clarify with the edit in red.
Just to make it more interesting, as usual there is a totally unrelated to motorcycles part that will not rust in the mix, can anyone see it?

Yes I could have raked the grass but that would have been too easy, a little like high definition photos that show better detail when blown up!
Chippy, the rubber hook thing is the tank rubber with 1/3rd missing, I can't show a high definition photo as it went in the bin. Here is a closer photo:

Sorry Alastair, David and TerrY, no Cigar!

Well there is something weird there but I'm only guessing what it is. In the photo with the front wheel on the left side of the photo, there is something on the grass under the little end of the conrod and maybe partly under the front tyre that doesn't look like part of a TY. My guesses are that it is either ammunition for a Lee Enfield 303 or a brass writing pen.

Bullseye David, your aim is straight and true! You have pulled the trigger and hit the target! My clue was fairly simple, a magnifying glass was better than electronic zoom in this case:

Here is the other that came in the job lot:



You guessed it : Steel Tank!
MERRY CHRISTMAS EVERYONE

Cruel cruel man Greg Harding.

Alastair.

Now that Sherco Shirley has both an Italjet Piuma and a nice fresh TY175 motor, maybe the two things combined would be something pretty good??????

It looks so small in that frame poor little thing.
I am sending two TY 250A engines to Dan to work his majic on aswell. Amazing the weight diferance between the 175 and the 250 motors. The plan is to keep one of the 250s and do the shedworks mod etc and sell the other to try and recoup so money.

Sounds good. Which "shedworks mod" is that?

I rode a mate's RL250 back in the 70's (and repaired his frame) and as much as I enjoyed the bike it did have it's shortcomings. For all it's faults I still wanted one and about two years ago one became available.
The frame had been repaired very badly, three times, in the usual place and was so bad it was broken on the other side as well.
I repaired it and then saw Greg Harding's "squeamish" and decided it would be an interesting project to so something like it. I'd like to acknowledge Greg's work on his bike and thank him for advice on a few things I couldn't work out from the photos and posts.

This is what I started with. I had to remove the section between the red lines. I friend in the aviation industry got some 3/4" 0.080" (2mm) wall thickness 4130 tube
