Having shims in additional sizes besides those in 0.05mm increments, such that one could put all the valves to the upper side of the clearance range would be useful and likely preclude ever having to do anything other than check on the valve clearance for quite a number of miles.

lets say I have 100 of shims in the 2.80-3.50mm thicknesses I wanted thinned to 2.66mm +/- .02mm actually having .02 to .03 variation is ok as all of them would be mic'd for size afterwards. I've also found that using a surface grinder is the most common way of doing this. followed up with a polish. Here's a thread about doing it in a lathe & chuck. Facing the parts to size was to be the more challenging task, since I had to face off .130 and only had about .160 to hold on to. I did this work on a Hardinge HC chucker and discovered you can install the chuck over a collet in the spindle. I grabbed the previous mandrel in a collet and installed a bolt as a back stop for the shims. I used a bellville spring and a washer to back up the shim. I put a piece of brass in one of the round holders, gently chucked the shim against the backup washers, and pressed the brass against the shim while the spindle was turning. When done right I could hear and feel the runout approach zero, then I would stop the lathe, tighten the chuck, and recheck the runout. Here's the kicker, I used this procedure 8 times and I was never more than .002 different on gage depth of the shim after tightening the chuck. I don't have any pics of this process, since I was busy making money, but this process is a simple, quick, and accurate for turning disc parts. These jobs are the type you can easily lose your butt on because it's not economical to turn step chucks and it can take a long time to chuck each part. The secret to getting the part to chuck quickly is the bellville spring, it was sitting on a pilot on the end of the backup bolt, the purpose is to provide a gentle spring force to allow the shim to line up. It's a remarkably simple and repeatable way to chuck parts. Also, discovering you could use a collet to hold a depth stop while the chuck is installed, was a pleasant surprise. http://www.practicalmachinist.com/vb/general/clever-method-turning-valve-spring-shims-203589/

Thanks. for those wondering what a VR LM7805 is: http://www.eidusa.com/Electronics_Voltage_Regulator.htm

Has anyone machined valve shims (or had machined) to a new (thinner) thickness? How about has anyone used shims that have been machined? Any thoughts on the matter? I know that at least a couple of Triumph riders have had their 25mm valve shims machined which are the same shims used by our V4 Yamaha engines. I see one valve & heads tool maker makes tools specifically for doing this ($500 tools). What I'm thinking about is possibly buying some used automotive 25mm shims at a good price if machining them to usable sizes is possible. This would also allow me to fabricate shims of sizes that aren't normally commercially available. (they are normally only available in .05mm increments). Only one side of the shims would be machined and that side should be placed down in the bucket, allowing the cam to ride on a origonal side/surface. Last thought. How much would/should a machine shop charge for this service?

any problems with your LEO's if you have blue lights in a colored Christmas light strand on a vehicle? I just bought a 60 light LED strand from Walmart for $6.87 and am going to play with this a bit. It has 6 of the diode/resister tubes in it.

Mark, I'm glad no one was hurt. earlier this year the drunk could have got both of us and 2 RSVs in one swoop. hopefully he has enough insurance. And can I presume the driver with suspended license is now in jail?

Do you have a i-pad

I will probably buy an Android based tablet soon. But it needs to have a 10inch screen and support the latest version of Android, v2.2 or later. Here's a review of the Archos 5 http://reviews.cnet.com/8301-12519_7-10376248-49.html?tag=contentMain;contentAux -
My dad was a broadcast engineer. He worked on towers a lot. I went up on one much shorter than the one in the video with him once. I don't think I'd care to do it for a living.

Concerning prices for checks at BOA. I get a flyer every week from a 3rd party check printing company. http://BradfordExchangeChecks.com that I'll use when I do need to order any more checks.

yer a SPEED DEMON Charley.... speaking of speed, did you ever try an ice runner (with a sail)?

I just had to start a new check register. Its funny thats its still called a check register because between Nov 2009 and Dec 2010 I wrote 12 checks in 13 months. So, thats less than 1 a month. Most of the checks were for taxes of one form or another. But the local tax office now takes debit cards, so I suppose most of the checks I did write were really unnecessary. I fact, it appears that a check I wrote to The Ponderosa in Cody WY, which doesn't take cards and the 2 checks to buy my 2000MM RSV in April were the only checks I wrote that couldn't have been done electronically. The number of check registers I get when buying a box of checks doesn't last and I go to the bank once a year or so to get a new register, and cant remember the last time I actually bought my checks. Maybe 5 years ago when the bank changed ownership and its name and account numbers?

I'd be careful assuming the voltage on unknown LEDs (or LEDs that don't have dc voltage rating in the documentation). Most small LED's are 2-3 volts each. To get these typical LED's working from a 12volt battery, one would want to construct a SERIES of about 5 of them together. In electrical terms a series circuit is components tied together end to end (observing polarity if important for the component type). A parallel circuit is multiple components tied between the same 2 wires. Concerning the voltage rating of an LED. I haven't followed recent developements in higher power or lumen rated LED's, so things may have changed, but the LED's on a string of Christmas lights I just checked the included documentation for were rated at 2.2-3.8 dc volts each.

welcome. There's a bunch of us in the SE states, I presume you've already seen.

And it also looks like they're somehow associated with http://wireless.1saleaday.com/ which is where a number of us bought the $9 mini video cameras a couple months ago.
-
yea. I want to know if that works....
-
see you again in a few days. hopefully all fixed up.
-
I'll keep an eye on this rally and make it for one day if I can.

I'm sure Annie chased the burglar to the end of your driveway....

either that, or the reason he's had so much trouble fixing it is that he reads the maintenance manual upside down.

Bubba needs one of those....

St Jude is one of the most worthy causes to support. I'm glad this forum helps every year.

Nope, not me. I looked at GW's closely 2 years ago and decided to go the Yamaha route. The RSTD and RSV feel more like what I expect a MC to feel like.

which reminds me that its time to start the Turkey soup from the leftovers...

The coupon was just good for Thanksgiving Day, I believe.
