Hadn't done anything with mine in months, but I'll be taking it to the shop along with all it's extra parts etc, etc, then I can get back to finishing up the extra welding to beef up the frame, then strip it all down to a bare frame and paint it.
I got my Tig set up at the shop finally as well as the plasma cutter so I got something a bit better than that cheap HF wire feed welder that actually does really well... I built a really nice guardrail for my alignment pit and used that little welder exclusively and it did great.
I also got a nice 20 foot long steel work bench where I plan to mount my lathe, drill press, bench grinders, and a few other stationary tools... Mostly set up for welding and fab work, but once I get the back of the shop set up a little better I'll build a few more to see how they sell in this area, then I also got this Morini engine I'm thinking about putting in a trike since it's a bit too wide to be practical on a bicycle, so once I find the right frame I'll begin that project.
Right now I'm just too busy during the day to mess with the bicycle projects but I'm also really missing all that tinkering... and there's nothing wrong with staying a few hours late to do my own stuff after I close up for the day...

shimmed my wheel over to the pedal side more with a thick 2mm washer and a thinner nut on the opposite side. also changed my rear 20" specialized 2.125 roller tire with a 1.95 cst cyclops and aired front and rear tire pressure to 60 psi. Also i washed my clown nose air filter on the 21mm phbg carb in the sink, dried and am going for a ride.

Just completed a 'check every bolt, lube everything lub-able'. Gonna take it on a camping trip to SE Oklahoma. That seems to be where the weather is most favorable. Was planning on northern New Mexico, but 28* (-2* C) & precip didn't warm my cockles.

Not really on the bike but I got bored at work and welded up a small engine test stand that bolts the engine to a post for the front mount and the rear mounts to a small plate, then the whole thing can be C clamp monted to a table or workbench. The unit is small and compact, but very sturdy so it's possible to run the engine off the bike by using an aux tank like those for synching motorcycle carbs and a pull starter or a cordless drill with a beefier nut installed on the magneto side of the crank.

The main benefit of this stand is that I have something solid to mount an engine on besides the bike for other purposes like assembly, disassembly, and test fitting parts I've been fabricating in the shop when I have free time.

Right now it's almost done but I need to refill my argon bottle so I can finish the welding.

Cool, Dave! Pics?
Was goofing around with Manic about doing some thing like that as a emergency generator. Have a truck alternator with a sprocket on the shaft.

Double duty and a conversation piece.

No pics yet but I can take some here in a little bit... Right now I'm out of gas for my TIG welder and I'm hoping I can get my bottle filled in the morning before I open up shop...

Sounds like you got a similar idea because I was thinking about what I could use as a dummy load for the engine to make it possible to do the break in before installing and an old generator came to mind since it's compact and capable of putting a decent load on these engines. Another thought I had was to let it run a large shop fan but then it wouldn't be compact anymore, but with a generator it caould mke the electricity it takes to run a fan which could be used to keep the engine from overheating on the stand...

I have similar for my CDI tester, but decided not to try one for the whole motor as the shaft may get its threads stripped when trying to start a high compression motor, plus I may get my wrist broken if I don't get the drill off that nut very quickly when the motor starts.

Swapping sprockets to change ratios for an experimental clutch. Gnarling the driven shaft. It was not turning the bearings and wore valleys in the shaft. That was a new one on me and didn't know what was causing it until Russel pointed it out.

Thanks, Russel!

That is great, Crassius. Must make DXing a breeze. Did you post a thread?

You guys got me thinking. I have an old exercise bike thing in the cellar. The rear wheel is just a huge flywheel. Gotta think about this. Would be really hard to get started. hmmmm.....



But for a regular engine stand and to start the engine with a drill (batt. operated for power outages, to be used as a generator) Use a ratcheting socket?
