Title: Boredom II, the sequel
Post by Armen on 07/28/17 at 17:47:47

So, I finished up the base for the motor stand. Just need to clean up a few welds I rushed through and rattle can some primer and paint.
Have some ideas for a way to hold the case half horizontal to assemble the bottom end. That'll be next.

Now it needs a electric motor to make it rotate maybe a gearbox to rotate it at different speeds and solar powered ! Looks beefy enough for a car engine !

Funny my engine stand was just using the 2 long front foot peg bolts in the bottom 2 holes. Push them half way in and it holds like a champ. Didn't fall over once when assembling the top end. 8-)

Savageman, sometimes it isn't about how little you can do ;)

A photo-tour of the shop would be nice.

Armen, But reinventing the wheel seems like a hugh waist of time. My dad was a mechanical engineer and always wanted to reinvent the wheel for simple things to prove he could. ::)

Are the wheels on your car marble or granite?

The wheels are aluminum alloy and the tires are Dunlop. I think they are made of synthetic rubber. D'oh! ::)

And it took Michaelangelo 4 years to paint the ceiling of the Sistine Chapel. If he'd used a roller he could have been done in a few weeks.

Sometimes its about taking time to make something nice just because it is nice.

A rudimentary stand for cam chain or head work isn't the same as one that would make loading the transmission guts in a side.

Title: Re: Boredom II, the sequel
Post by Savageman on 07/30/17 at 15:49:31

That wouldn't work for loading transmission guts. It appears to hold the entire case in place after assembly.
I must have bruised a few EGO trippers here. Don't trip over your EGO! ::)

All your FAULT Armen...

The half case should be easy , a plate cut out to the shape of case with 1" tall pegs at lower 4 motor mount bolts. Simple lay the left case on first , install crank,counter balancer & trans , then right case. Then into your other mount. Simple no bolts , just use that free and abundant Gravity !
Might need some spacers I'm not sure if all the mount are the same width.

An arm with 4 pins the size of the large bolt holes will work. Probably a piece of aluminum or welded 1/4" steel with some reinforcement ribs welded on. The wheels and gears are turning now.

Post by Armen on 07/30/17 at 19:35:11

I'm thinking a flat plate with threaded holes in the pattern of the motor mounts. Threaded stand-offs that can be threaded into either side of the plate so that the motor can be disassembled or built from either the right or left case.
Once I have the motor stand painted, I'll move on to the horizontal gag.

That's even better than my idea Armen. I was just thinking left side first cause that's how I built mine. Far more sophisticated than my cut wooden blocks. ;D

Every motorcycle shop I have worked at used a small pallet made from 4 boards when separating the left/right side center cases - 2 boards on the bottom and 2 laid crosswise on top and screwed together to support the left side engine case when removing the right side. The boards were about 18" long and were 2x4 pine lumber (hardwood would be the deluxe model)! The height allowed the left side of the crank and countershaft to clear the bench, and the wood was soft enough to prevent any damage to the gasket surface. When the engine is torn down this far - there is no head or cylinder....so the engine is pretty light at this point.

The engine mount that Armen is making would be extremely handy....I am probably going to make a much simpler version that is just some angle that can be bolted to the motor mounts.....and to 2x4's on the bottom to keep the engine upright.

So, here it is. Dummied up. Not painted yet.
Found some scrap 3/4" plywood. Screwed together two layers.
Laid one crankcase half on the wood. Used a transfer punch to locate the holes.
Poked in some holes. Screwed in four 3/8-16 inserts into the plywood. Used some scrap lengths of 3/8 threaded rod and a few nuts and washers.
The holes go straight through, so the threaded rod can be inserted from either side, making it possible to lay either the left or right case half on the gag, depending on which side you have up. The nut and washer on the bottom stiffen up the rod, the ones on the top set the height needed for whichever half you are using.
Pretty stupid simple, easy to make, just some scrap and a few inserts.
I know, you used a petrified armadillo carcass when you learned this in the Army, blah blah blah.
Just posting this stuff for general interest, and maybe inspiration. Not saying anyone has to do it this way ;)

Nicely supports the case and simple stupid easy.
Really Armen we were expecting something Grand and completely over done ! ;D ;D ;D

Title: Re: Boredom II, the sequel
Post by Armen on 08/04/17 at 02:44:20

I know, Rulttly. I was going to take some aluminum round stock, turn down one end to fit in the case holes, and thread the other end. Then I reminded myself that sometimes, Done is Beautiful. And with this set-up, it's easy to adapt to other motors. All I'll have to do is drill more holes, install more threaded inserts, and adjust the height of the nuts on the threaded rods.

Did you say "drill more holes"?? :)

Armen , Just messin with You , consider that idea as stolen for my next engine build !
