Back in July of, I think, 1980 I was in Portland, Oregon installing some machinery in a factory there.  At the end of the day we went to a nearby watering hole for Happy Hour and proceeded to empty a number of bottles.  About 10 o'clock we were getting ready to leave and mentioned to the server how quiet the place was all evening.  She replied that it was really pretty busy, everyone but us, who were from out of town, was out drinking in the parking lot and watching St. Helen's erupt.  By the time we got outside, it was just some smoky red glow through the trees.

I still have the next day's newspaper with a big photo on the front page.
That was a lot of bottles you consumed. It happened end of May, 1980.
drunken

Mates of mine in the bike business say that for two or three years after the explosion and subsequent ash settling they were replacing air filters and combi switches on the handlebars of bike in droves. The grit from the eruption got into every crack and crook it could for miles and miles around and wore them out.

I just had to dig out that old issue of the Oregonian from July 24, 1980.  Front page has a huge photo of the mountain with a plume of smoke.  First line of the article "After 3 eruptions on Tuesday(July 22) things began to calm down on Wednesday". 

I guess I got it wrong on when I got the paper.  I have a hard time remembering details of what I had for breakfast.  (Did I ever tell you about the time I made breakfast twice in one morning?)

It continued erupting for months after the initial shocking blast. No surprise it was still smoking and firey in late July. 

A coupla years back I walked into the park as far as I could after riding to the east side of the dome to the parking lot there. There was a 900' bubble forming inside the caldera that smokes to this day. She is not done yet.

You can hike up the back side of it, walk along the top rim and look down into the crater of MSH. BTDT.  The last hundred yards or so is a PITA though. It's fairly steep thick ash so it's one step forward, two steps back on that last part of the hike.

From Windy Ridge, note the 'bump' in the centre of the caldera which is visible in Duck's photo but from the south side.

On a busy weekend the National Park rangers give on the hour talks on the volcano. This view is from a short walk up the lava silt to a ridge which gives an expansive view of Spirit Lake, or what is left of it as it now lies 800' below the new lake.

The first blast completely denuded the hillsides to the north for ten or fifteen miles. The valleys below mainly survived the extreme heat, but creeks and rivers silted up as the lava flow moved out and away from ground zero.

Big Block K100 - Page 7 Imag2616
Some of the logs, former tall timbers, are still visible in the lake after forty years, or left to dry rot on the barren ground, but new trees are slowly returning, some planted, some eking out a living in the few patches of still-arable soil.

It's a magical, eerie place. I try to ride there a coupla times a year as it's about a two and a half to three hour ride from my home.

Windy Ridge is one of the better rides in western WA.  The only problem is how absolutely shitty the pavement is on FS-25 coming south out of Randle.  Last time I was there in 2017 it blew a fork seal on one of my K1100LTs and even with fork boots it spewed fork oil all over the right side of the bike. Arghhhh! Evil or Very Mad

Agreed, the road surface is full of potholes and unseen dips that wreak havoc on forks. This is why I like BMW's Duolever so much. It eats the bumps while maintaining reasonable steering control. Your 16 has them. Try it again soon and see.

A quick Easter Sunday arvo burble in the neighbourhood revealed this sunny view of town, over Chambers Bay and across to the Olympic Range in the distance, from the local town of Steilacoom, pronounced roughly as still-a-cum, after a local tribe.

I park it right next to Big Block, so it sort of qualifies. Today was a brilliant, mid-60s day, sunshine all around, nary a cloud to be seen unless I squinted. Got a quick fifty miles in on the Mystic. I don't ride it much. It's plenty of bike, and I spent many, many years on Airheads, criss-crossing the States, Canada, Mexico and central America, up and down and all round the East coast and right up the guts of Australia on them. This one has great, four piston Brembo brakes, Paralever, a tall final drive, low-compression 980cc engine with 32mm Bings, but it's not exciting. It doesn't make my pulse race. It just plods along, smoothly, sedately, softly, quietly, and that's alright sometimes.

The BB has been using, quite successfully, twin 305mm x 4.5mm discs from an F800GS with 4 piston Brembos (32/34mm) from a K1100RS with a 20mm K1100RS master cylinder. Time for an upgrade. 

I have a straight set of 320mm x 5mm discs from my long-gone R1150RT and some 4 piston (32/36mm) callipers from a new series K1200GT/1300GT which use a 16mm master cylinder.

The sturdy aluminium brackets which will splay the callipers away from the Marzocchi forks are being fabbed today. These brackets will attach where the original Brembo cals went, but with a 15mm increase in disc diametre they'll swing the callipers out and away just enough to cover the brake swept area and align the pads in centre over the discs.

Big Block K100 - Page 7 20180411
These ol' red boys and their accompanying 305mm discs will be stored for another project. They were always a pain to slide off the discs and away from the rim when attempting a wheel removal. The new callipers are a slimmer, and much lighter, design even with the larger diametre 320mm discs.


I might even be able to join the stoppie boyz down the local bikie hangout. Nah.

If I'm not tending my vegie gardens, making dinner for my back to uni for her master's at a 'mature' age partner, or doing the dishes afterwards, I'm in the garage. 

My old gramps used to call it 'pottering'. I s'pose I can call it that too. I'm now nearly his age when he said it.

Bonus that she also works for the uni, so it is income-added for tax purposes rather than an additional and hefty expense, and she has permission to study whilst on the job. She got all of her degrees later in life after the kids, etc. It amazes me how she can tuck into it for hours and hours on end quietly in the home office. I'd go mad after an hour, eyes wandering off for something more about what I like rather than what someone tells me I have to do. I am sometimes a player in the Short Attention Span Theatre. Next!

While waiting for my machinist mate to cobble the aluminium calliper brackets together for the larger discs and later cals, I need the BB to use as a runabout round town. I have a coupla sets of three spoke K11 wheels, these two with near-new Battlax BT016 rubber on them.
Damn, would I ever be seen on the road with no front mudguard? Oh, the shame.

As I prepare the BB for the 320mm and later calliper front brake upgrade and am rolling the front wheel with tyre, discs and bearings round the shop it got me thinking. What a portly piece of kit it is. It's a K1200LT front wheel that I've been using since the build - got it cheap and had it straightened. Added up it is 16 lbs (7.25 kg) for the bare wheel with bearings, 2.9 lbs (1.3 kg) for each 320mm disc, a pound for the miscellaneous screws and spacers, and whatever a front tyre weighs - say just over 9 lbs for the Pirelli on there. All up that's in the neighbourhood of 32 lbs (14.5 kg).

I have a spare 3.5 x 17 wheel on the tyre & wheel rack from my long-gone 2004 R1150RT. It needs the longer spacer to replace the speedo drive gear on the left hand side, and a 60x30x7mm seal the fill the area around the spacer and axle - seals on order from McGuire's and correct spacer from a K1200RS in stock. This wheel weighs just 12.9 lbs, a set of good, used Braking-brand wave discs I had for my K1200R weigh 1.3 lbs each, plus misc attachment hardware. With the same 9.3 lb Pirelli tyre we are just at 25.5 lbs (11.5 kg) all up, a significant unsprung weight savings of 6.5 lbs or 2.95 kilograms. Bloody hell. That'll make the Marzocchis work more efficiently.

The wheel still has a thin layer of Alcan Highway mud randomly caked on it from my June 2016 trip to Yukon Territory, Fairbanks and Anchorage. It's like a preservative. I'll have to get to work chipping it off. Wonder how much that will save me in added weight?
scratch study 
lol!

Hot, soapy water and an old kitchen scrubby out under today's sun shininess and the wheel looks the biz - all evidence of Alaska removed. The sparkling R1150RT wheel now has Braking wavy gravy discs on it, Renthal sintered pads (made by Dunlopad) are fitted, and they're ready to be attached to the Marzocchi forks. Tomorrow and the next day we measure, drill, countersink, cut and machine the aluminium mounts for the K1300GT callipers to fit. I could almost chuck the wheel around the workshop like a frisbee, such was the weight savings.
cheers

It's fast approaching 29C (84.2F) here today, which will be a record for this day in Lakewood, Washington! In honour of this I had some errands to run and so took Big Block out for a downtown spin and to try out the temporary Battlax BT016 tyres over K11 three spoke wheels.
Fine indeed, but I prefer the look & feel of the K12/R1150 five spokers.

Anyhow, I had to stop at the local Beemer dealer to pick up some spares I'd ordered and as I rolled off the exit and downshifted....the bike stumbled. A few good revs and it settled in for the coupla hundred metres to the shop. I'd been on a few longer rides lately, I've not got a low fuel warning light that works, and I just plain sort of forgot.

Business done at the dealer and I took off down the road toward the nearest station, about 1.5 miles away. Stumbles continued her clown show but I kept her going, doing 55mph in a 35mph zone. 100 yards from the Union 76 station she stopped, but as I was travelling along at a good clip, no constabulary apparently hiding in the suburban bushes, I rolled right up to the premium pump! The stated 22 litre (5.8 US gallon) tank took all of 6 gallons. It was the best case scenario.

Incidentally, I paid $2.39 per gallon for 92 AKI premium.

Home now, in shorts and sandals, sunshine all round, preparing to rip the scabs off a coupla cold little vicious ones and sip the frothy nectar in celebration of Mum's Day. 

Cheers Mum, all the way over in OZ at 83 years of age doing the pandemic alone.

Moving slowly, but making progress, as my needs are secondary to the machinist's ongoing projects. He urges me to watch, assist and allows me to ask stoopid questions. Yesterday we had time to spin a new axle spacer collar for the R1150R/RT front wheel for the Marzocchi forks. Early next week it's the brackets for the callipers.

Making certain the wheel is spaced perfectly centred between the fork legs. Note how close the brake disc screws come to the inside of the fork leg?! The stock domed screws have to machined down or replaced with these later model (R12/K13, etc) flat T30 Torx screwsBig Block K100 - Page 7 20200513
This gap between the wheel bearing's inner race and fork leg needs to be measured and appropriately filled for proper bearing preload.
Big Block K100 - Page 7 20200521
A stock K1200RS axle spacer is too short for the R1150RT wheel, so a spacer 3.5mm longer (at 33.5mm) is made up.

From a rectangular block of cast-off aluminium comes a 33.5 x 30.2 x 20mm spacer. This
is after the soon-to-be-finished spacer has been sawn off this chunk.

Cheers, 88. It's only a 3.5x17 from an R1150 Oilhead, same dimensions as a three spoker from a K1100RS, but I reckon the camera's lens distorts the image a smidgen. The wheel I replaced came from the big beasty K1200LT, and was the same size, just a beer belly bigger in heft.

Time. Some have heaps of it. Others less so. Still others require plying with alcohol in order to be able to use their machine shop tools. Kentucky Bourbon & Oranjeboom lager do wonders when placed strategically next to a favourite office chair.

Result, a rough template in blue.
Big Block K100 - Page 7 20200529

Template with 8 & 10mm tapered head screws which will sit flush on the final aluminium plate, which is 10mm thick as opposed to the template's approximate 5mm thickness, so a much heavier gauge. The final plate will also sit closer to the line of the fork leg than this template.
Big Block K100 - Page 7 20200610

Collars sit behind the plate with size-appropriate 8 or 10mm holes. Correct spacing to centre the callipers was done by milling the head off two 8mm screw and "pointing" the ends sharp so they could be finger tightened or loosened into the threaded bosses of each calliper so they'd reach outwards to the alu plate, then pressing tightly against the plate, indicating where the 8mm holes needed to be drilled. Voila!
Big Block K100 - Page 7 20200612

The 10mm screws with Nylocs and stainless steel washers hold the aluminium plate to the Marzocchi forks. The 8mm screws hold the calliper to the plate by threading into the calliper bosses. Twist under braking will be negligible due to the rigidity of the 10mm plate and its mount points. The final, thicker aluminium plate will be painted black with the stainless steel Allen head screws sitting flush with the outer surface for a clean look as well as being firmly located in their 82 degree taper for added strength.
