wanted - moto giro bike

Other than the latest run on and now complete lack of toilet paper and paper towels, fruit, meat, RAT tests paracetamol and a few other bits and bobs it's fine when I can muster the bravery to leave the house. That's because with one of the highest vaccination rates in the world we are all now safe as houses and are free to mingle and get and pass the virus to all and sundry. So now tens of thousands have it and need to isolate so supply chains have collapsed.
But it's all good as I now have the booster. Every time it looks like improving some new nightmare begins. And did I mention it hasn't stopped raining since Christmas. But at least we don't have any Bushfires around here, too wet. Cabin fever has crept in. I need a dry day for a bike ride bad.
 
engine cases and other bits back from the vapour blaster. You can see the results in the first photo below. Sort of a satin finish. Looks better in the photo than in real life, the cases show lots of marks and dings and divots and scratches, but look 1,000 per cent better than they did before vapour blasting. The one case half also still needs a small welding repair. The 18 mm Dellortto carb cleaned up beautifully, looks like a piece of jewelry.

my inexpensive blind bearing removal set arrived from an Amazon vendor. Seems decent/Ok quality for $100. Now to source replacement bearings. Only one of the bearings in the cases was still serviceable, all the rest were quite "crunchy" for lack of a more technical description.

Hi Cam

Good question. I lost a lot of parts and tools, not necessarily all from fire damage, but also from the insurance company clean up crew. The insurance company had five very pleasant non English speaking women who knew nothing about tools or motorcyle parts working in horrific conditions in the wet and cold and filthy burnt out shell of the garage without adequate lighting or heating for 5 days, sorting out what was suitable for cleaning and restoration and what was not. They filled a large haul away garbage skiff with stuff that went to the dump. I was still recovering from pancreatic cancer surgery and could not supervise. I think anything they did not recognize as having value, or did not know what it was, they just threw out. A year later and I am still figuring out what I am missing.

The entire mess is winding its way slowly through the Courts, my insurance company suing the insurance company of the shop that had just rebuilt the mechanical fuel distributor in the Bentley, etc., the shops insurance company insisting I must have done something to cause the car to catch fire, etc., etc..

When I got accused of intentionally burning down the Bentley, i pointed out that if I had intended to do so I would at least have made sure the car was insured for more than just what I initialy paid for it (having thrown another $24,000 in parts over and above the purchase price plus hundreds of hours of my own time at it since i bought it), and more important, I would have backed it out of the bloody garage before the fire........

With the insurance, my intention had been to have the car properly appraised after I finished it and then properly insure it for finished value, but I never got the chance. Of the 9 motorcycles in the garage ath teh time of the fire, the only one not insured was the three quarters built Garelli, I had almost $5,000 and a bunch of time into that, no insurance coverage for that either. A bunch of the Garelli parts disapeared in the subsequent garage disaster clean up, I suspect a bunch of Garelli parts went to the dump as well.

On the subject of cheap tools, the inexpensive blind bearing puller broke on the 6th and last bearing in the Gilera cases. No such thing as good cheap tools apparently. $100 to pull 5 bearings and fail on the 6th, so $20 per removed bearing....... Going to have a chat with Amazon about warranty and replacement, hopefully with a credit towards upgrading to a better set.

One shop where I was the workshop had a part-timer who was an insurance investigator. He told the story of the V12 Jag belonging to a well known senior crim here. "Stolen" and burned. It had a vinyl roof covering - and visible in the remains of the vinyl was the imprint of the ignition key above the drivers door....Payment declined.

Hi Greg

I had the pleasure of the fire department investigator, then the arson investigator from my insurance company, then the arson investigator for the service shops insurance company. All accusing me of somehow setting fire to my own car. I love insurance companies.

On a happier topic, looking at the now vapour blasted engine cases of the Gilera, they still show all the bumps and bruises and scrapes and corrosion of their 65 + years. Now that they are as clean as they are going to get I am now pondering sanding them heavily then polishing them. I have mirror polished various Laverda engine covers with my home made 5 hp polishing rig over the years but have never tackled engine cases themselves. There is enough pitting in the cases they will never be perfect, but I am mulling over having a go at mirror polishing the case halves. I am likely a week or two away from having a go, still have to have some welding repair done on one case half, and thread inserts into the two broken 6 mm bolts I could not get out. Thoughts or comments on polishing engine cases? I am not happy with them the way they presently are, I suppose the other alternative would be to paint them.......
 
Well, when my bikes were burnt, they weren't insured for arson but tools were stolen, my trailer was stolen, a police woman from the scientific department turned up, said "it's terrible what they get up to", had a look at an imitation wood Formica topped table that had been moved in the hangar to get the bikes out and said " I can't take fingerprints on wood". She then pissed off and that was the end of it.

Tools and trailer were reimbursed providing bills of sale were produced.

I'd lean towards grinding / buffing / cutting / sanding all the damage out, up to the point before which you'd start polishing, then send them back to the blaster to get the nice matte finish again. The blasted finish will hide more blemishes than polished, so if you can get them to the point of being viable to polish they should subsequently look great re-blasted.
Something about sandcast finish cases and polished covers, you know it looks so good. Polished is going to look a bit 'chav' (as I think the poms would delightfully put it). Like it should be lowered till it scrapes the ground and have a doof-doof stereo and led blinking lights or summat. :D
 
I seem to recall that the rough casting gives a greater surface area for heat dissipation, any thoughts?
To remove blind needle rollers I just carefully tack weld a small plate with a nut behind it to the bearing and extract it with a threaded bar/tube/ washer type home made puller while there is still heat in the area, the bearing is going in the bin anyway. That should work with other types of bearings.

Rough casting does increase the heat exchange surface, but is that vital with an engine developing 50 HP/litre?

Might be "only" 50hp/litre, but the little bugger will be running at max rpm for most of its future life. It can do with every little bit of help it can get... :rolleyes:

These little commuters were quite lively engines for their time.

A skilled bead blaster can by choice of bead and pressure make them look like sandcast again. The only problem with this is that in my experience they stain very easily afterwards.

I had a scruffy set of triple rearset plates, pegs and levers bead blasted. They became scruffy again in months. I had them bead blasted again, then annodised mat silver.

They looked great and stayed cleaner longer and were easier to clean than ever.
