What did you do to or for or with your Laverda today?

Which member lives in Nooj, Pat? Looks like an awesome ride. I didn't fancy joining the fun on the piccolo ZZR250. Spent some time on my sidecover mould plug/s instead ... after a 6-8 week forced break from work on the SFQ I'm keep to move things along again!

Trailered the bike out to THE FIXERS place on Sunday to get the valve clearances and head toqued after a solid years hard running. The trailering was done so the engine was cold to measure. I was still having an issue cleanly getting 1st gear after replacing the front sprocket when it and the new chain went on. Seems the engine has settled in nicely, clearances were the same and no change in head toque needed as well. I am so happy that has happened. Stupid me had just done an oil change so the gear change issue needed the bike leaned over on a car tyre and a strategic trolly jack to allow the rear wheel to spin. After umteen tiny adjustments, it's much better but it seems my C shaped gear selector hook gadget shows some wear and needs replacing in the future. I really hate the Russian roulette of playing with this, and I hope to avoid any more trouble finding 1st gear at traffic lights. So the bike is now all set from the high-speed antics of The Delegate ride new month, fires allowing.

Hey Quentin,

Did you fold then form & weld the corners?

Or did you form the entire shape over a die?

I think it's a solid piece of ally with the corners machined 1/4 round. Too be used to make a mold from which the final cover should be layed up in carbon. Correctamundo Q?
Personally I'd have done it out of MDF and painted the finish cause it's easier to shape MDF than ally.
 
Rob B gets the elephant stamp. Yes, a solid 12mm alloy plate with the edges rounded using a router bit in the lathe. I really wanted the recessed fixing bolt holes and as I can't spin something the size of that plate in my little Emco I used my boring head to make the holes then made the plugs to fit (pictured in the lathe chuck). Maybe MDF would have been easier but really it wasn't that hard to do. Most time consuming bit was rounding the edges. That would have been easier with MDF as I could have had the sides cut dead square off-site then used the roller guide on the router bit for edge rounding. BUT - how would I do the recessed screw holes?? Everything is just time time time anyway.

It's a reversible plug, so I simply flip it over to make the other sidecover mould. For that I need to make a flat 'tray' a little larger than the plug then pour silicone over the plug. Remove and reverse and repeat. Bingo, two moulds.

Probably make the side-covers out of fibreglass Rob. Gonna be painted anyway. Or do you think I may as well make them out of carbone? never done any carbon layup - is it easy for something basic like this?
 
Hey Quentin, if you havent done much fibre glassing then maybe just stick to that, its cheap, relatively easy to use and the weight/ strength difference on such a small job is minimal.
Make sure you wax your plug about 7 times, wax on wax off and also use a mold release agent if you can cause when they stick they really stick.
I once had a beautiful timber dinghy split down one side cause the mold wouldn't release, repairable but a pain in the butt.
Yes MDF would have been simpler, but hey thats a dam fine plug you have there.
We always paint our plugs cause it will show up any imperfections and thus not transferred to your gelcoat.
Enjoy buddy.
 
Sadly, mine is languishing in a strange shed waiting for its next ride. not long now. 8)

On the home front things are moving along, we should be set up in the caravan and shed by the end of next week.
