Restoration of Sandcast #97

[markb]

All bolt head markings were upright or one direction.  All flats of hex bolts were in line or vertical.  all slots of screw heads were in line.  He had boxes and boxes of screws, he would hand select each screw so the flats and the slots would line up when tightened in their hole.  

  Yikes!  Now there is an interesting challenge.  I can see where it would be possible to line up the heads in some cases - where you can rotate the nuts to make the bolt heads line up.  But looking at the right, rear bracket as one example, the bolts thread into nuts that are welded onto the bracket.  Therefore when you install the bolts the heads will end up where they get tight.  One could try different bolts to see which ones line up but I don't have boxes full of "Big 8" bolts to experiment with.  That said let me think on it for a bit....

There, I've thought about it.  Even I am not that anal.  They will stay as they are.  

Have you tightened the engine up in the frame? So that it does not rely on him even..
It may seem insignificant, but it limits the vibrations that could be communicated to the frame..

Not exactly sure what you mean.  I have torqued all the bolts to the proper torque except for the rear, lower rod which will be tightened when the foot pegs are installed.

So who of you are button heads and who are flat heads  . I know some may think I'm a Dick Head or even ahead. I do know I like a beer with a good head. U think I'll stop there  

Good, I think you're head-ed in the right direction.

Hi,
Keep on being anal on this matter and please take more pictures. My SC came in boxes without any bolts and it is a lesson for me to see what kind of 8-bolt is used at every place.

Super nice thread!

About number 8 bolts, getting them upright could be done with different thickness washers?
Or in a lathe nib enough off the underside bolt head.
Went to look at my bolt heads. Apparently only 2 for the right front bracket have number 8 heads!
Incidentally there is a 24mm hole in the middle of this bracket for my 1676!
None of the long cross bolts have .8 on their heads.
Any significance in dot on your long bolt is to the side versus underneath the 8?
I'm working in wood and it has been seen all screws are turned to same direction.
About tightening engine bolts.
Long ago an australian came past here in town on a Norton Commando, complaining of vibrations in frame.
We loosened all engine bolts and rode it up and down the street whereupon retighten, and he felt it was better.

You are serious guys with "8" perfectly aligned vertically?
You believe that the guys of the Honda factory in 1969 have time to align the bolts and screws "8"?  
It becomes a little crazy... I thought it was a joke at first...
The authenticity to the contrary they are not aligned...

This is a certainty!!

I've never seen 8's on any of the long bolts.  Not sure if there is any significance to the location of the dots.  I just put back what came out.

The engine bolt re-tightening makes sense.

The story ff my friend aligning screw and bolt heads is true. 

Otherwise,  i was just kidding Mark.

Screws are as used in the side covers etc, bolts are hexagon head fasteners, generally.  but just to confuse over here in the UK, bolts which are threaded all the way up to the head (as opposed to having an unthreaded section) are referred to as set-screws!

Stunning job Mark - a work of art indeed.

Steve, This may seem a little crazy, but good if it is real... Let's be crazy and I promise you that I will align my "8" Bolts on the two front motor mounts...

I figured you were.

I installed the exhaust spigots.


They look really nice.


Notice the radius on the angled sides?  Nice distinction on very early spigots.  The plates are thinner too – 5mm instead of 6mm.

Next project, the steering stem.  The races in the frame tube were pretty rough so I took them out before painting.  The last time I installed them I had a hard time getting them to go in straight so I made this tool.


Makes the job super easy.


Mission accomplished.  Never even dropped a ball.  The key is to have plenty of grease to hold the balls in place.

Mark .. I am posting your glass/silicone impregnated  sleeving, right angled terminals etc today  .. sorry for delau. BTW I am resurrecting the hot fused covers again.. watch this space!

Thanks Ash.  No problem.

Between vacation and a couple of business trips I haven’t had much time to work on the bike.  I’m starting to mount some parts on the frame.  I got the center stand in and I decided to use the washer method of installing the spring.  With someone holding the frame I used to be able to pull it on using a hook but not anymore.  I clamped one of the loop ends in to a vice and then using a piece of tubing over the outside of the spring; I bend it back and forth and insert washers between the coils.  It took me about a half hour to wrestle them in.  It seems one falls out for every two you get in.  The key is to try to bend the spring where you want to insert the washer.  I use #10 springs and about 32 of them will increase the length by about .75”.  Then you hook it onto the C plate and lift up on the center stand and the other end easily slips onto the hook.  It might take a while but no straining, no chipped paint, no skinned knuckles.


There it is in place.  Is there a “right” way to install it?  There are four possible ways.  As near as I can tell from the parts manual I think this is correct.  Any opinions before I remove the washers.  After that it ain’t getting changed.
