Also baking soda works well in a blaster. Washes off, is gentle.

Gotta love you Chris. :-D

You always choose the path less traveled.

I knew a guy that has 19 Rovers, 4 MGs and a bunch of Jags.

There should be an award for what you do.

Like maybe two bowling ball size chrome bearings on a plinth!!!!. :cheers: :cheers: :cheers: :cheers:

I don't post much on your build because it's scary stuff. :-o

You think YOU'RE scared, you should see my checkbook balance.

In the production categories, it's all about getting the right horsepower from the wrong engine . . .  :|

I used to get a lot of air cooled Ducati cylinders bored and honed
occasionally the sleeve would come out of the cylinder muff in the honing machine while it was being honed
This didn't do much good as the hone would grab the sleeve and use it to hone the cylinder muff
To get the interference fit back I used to take the sleeve down to the chrome platers and get some
copper put on it then put them back in
Never had one come out in the hone after that

Grummy!  Missed you, Bro!

According to the service manual, these sleeves are a slip fit.

Tightening it up a bit is a good idea.  I wonder if I can deposit enough copper on them to achieve an interference fit?

Given that we're looking to up the clamp load with ARP studs, I was thinking of using a deck plate to secure and hone the liners, which will stand a bit more proud than stock, and then epoxy them into place.  My concern then is to see that the liners all top out equidistance from the bore centerline, provided the epoxy is sufficiently stout to prevent shift during a face cut.

There's a lot of potential to screw this up, eh?  :wink:

Screw up isn't in your vocab.

It's called progress!!!!.

The bank is lucky I don't have plastic or a check book.

I'd ruin them, the bank that is. :-D

You're still my #1 pick for "Nuts" of the year and we're talking big chrome round ones. :cheers:

No, sadly, "screw up" IS in my vocabulary, and it has earned a legitimate home there - but I do try to keep it sequestered and under lock and key.

As to my nuts, this project is changing them from SAE fine to metric threads, and the screws remain somewhat loose . . .

 :cheers:

Mike, you need to get over here.

My biggest dream is to get over there but I'm afraid I won't want to leave.

Way too many good things going on there. The list is endless. :cheers:

Yep, after 20 something years doing this, I can still stuff things up
Although the guy I have working on the English stuff is much better at it than me
He as dropped three bikes off workstands in the last seven days
one Moto Guzzi, and two Vincents (one Comet and one Black Shadow replica)
Fortunately, there was no damage as they mostly fell on him.

Oh, and I've been here, just haven't had much to say.. Oh and building a Grummahal

You can put as much copper on them as you want and it rubs back off with a scourer.
Although if you want to keep them slip fit, get someone to make you a deck plate
you will most likely use it more than once and it should help to mimic the distortion you will get in the block from having a head done up on it
But you already knew that

Chris,
Deck plates are easy given bore spacing and bolt hole dimensions. Ground plate is off the shelf stuff. I assume sleeves have a flange on the top that fits in a counter bore in the top of the block. If the depth of each counter bore is miked and each liner is machined so distance from top of sleeve to top of block is the same problem solved. Easy job for retired machinist.

Terry, I'm thinking of offering up a junk head to use as a deck plate, but it will require some machining. 
That gets me the bolt holes where they belong, and then it's just a matter of centering and machining bores on an 88 mm spacing with enough overlap to hold it together during the hone.

I hope you'll be at PRI - I need to chat to you regarding some steering arms to minimize my bump steer.

It got ugly on the backup run . . .

Chris: - I'm planning to be at PRI as well - hope to see you there.

Do you have any plans to run the Midget at The Ohio Mile in 2016?

Also, if you need any plating recommendations, I do business with an excellent shop in St Louis (American Plating).

Fair question.  Mark is encouraging me to run the A-series again, and that's where I'd do it.  I think the I/GT record is still open there, and it's not looking likely I'll have the K-series together for 2016.

I guess it kind of depends how much I'm going to have to butcher up the Midget to make the K-series fit.

I'll likely make the drive out for an event either way.
