More front of engine & motor mount detail.

Research, research, research.

This first picture really clarifies several things for me, in that the motor mount tab is cast into the water pump housing.

 

The front cover/water pumps for the engine in the kit are cast as one piece & I'm going to separate it into individual components for better detail, but until I saw this pic, I was not clear as to how everything's suppose to look.

Now I can proceed on that.

I drilled through the lower water pump outlets & then with the appropriate sized drill bits, reached through & marked the front of the engine block for later reference.

Cut through the simulated motor mount cushions & separated the water pumps from the engine front cover with the jewlers saw.

If you'll notice in the first pic in post 121, the water pump has an outside bolt.

The kit waterpump has no bolt boss cast in this location, so I'll be adding a tab here to accomodate that bolt.

Big-n-littles, a hot rod staple, in 2 configs, Goodyear & Firestone.

Once again, this model project is to represent how I would do a 1:1 for myself.

It would be fitted with radial tires for the handling characteristics & eventually the scratch build will carry radial tires.

But these are plenty good on this one, for now.

 

Interestingly enough, the steel wheels in the kit are the same rim widths as the chrome alloys, so the big rear Goodyears look right at home on them.

Steelies it is, until I get some wires for it.

 

Going to get them painted this weekend & see how I like the burgundy on actual parts.

Thanks, Richard.

 

I had a thought...I've been "prepping" my parts for paint with a medium scotchbrite pad & noticed how it's difficult to get the glaze broken in some of the small tight corners for good adhesion.

 

I did some reading on soda blasting...baking soda has an abrasive quality about it...going to try pouring some soda in a tray & using a variety of sizes & shapes of stiffish bristle brushes to scrub the soda into the corners...

 

I used the bleach method, as suggested by Curt, to strip the chrome off of the heads & intake & it worked beautifully.

The parts came out of the bleach with a very slick shiny finish, so now I've been wondering how to get down in between the fins on the heads for good paint prep & am going to try the soda & brush method to see how it works.

looks like you are having some fun with this Ray, thats great to see!! every thing looks good so far, if you are prepping parts for paint adhesion, it really isn't that necessary, I know it is built in to us body men B) , the only prepping you really need to do is to remove mold seams and ejector pin marks, as far as adhesion, it really isn't an issue

I'm enjoying it, Bill.

Ya, good, thorough paint prep is in my DNA.

 

Cork sheet.

At .040, a little thick for most of the gaskets on this motor, but perfect, I'm hoping, for the oil pan gasket.

But, maby not.

Wait till I get some color on things & see what looks best then.

I want good, easily visable definiion where these parts join deep down in the chassis, while maintaining a reasistic feel in the piece.

I remember cork gaskets out of my past.

 

Bought a couple types of tacky glue also today.

Read a thread in Q & A about mock up adhesives.

I want to build this motor well enough that It will stay together for handling & display, but want to be able to disasemble it for measurments without too much trouble, when I start cutting the engine parts for the scratch built.

Might try some light brown construction paper to use as gaskets. The scale might be closer.

Ya the cork's way too much on the transmission top plate.

I've got some manilla folder that I'm going to try on it.

Motor looks better even now, without all that gawdy chrome smeared all over the top.

The magneto, even though it's cast to scale, is too visually large & overpowering for this motor.

Going with something smaller with a tower cap on it.

 

Rear fenders are going to have to be bobbed a bit behind the tire, which really fills out the opening nicely.  B)

Steel shafts coming for the water pumps, crank pulley & generator.  :D

Just need a few more proper sized drill bits.

That's better, but it still has that plastic engine that's been painted, look.

 

Humm...

Solid core, silver bearing solder...holds it's shape well, yet bendable...has a nice metal look to it.

It"s 1/8" & that scales up to a 1:1 primary tube of only 1".

I've also got some aluminum tubing that's 3/16, 1:8 of a 1 1/2" tube.

On a 1:1 motor, I'd probably go with the 1 1/2 size, but here, to my eye, I think by the time I got it all fitted into place, it would be too overpowering.

Kinda like the magneto, when I mocked it up on the front of the engine a while back.

 

Going to get the frame painted & assembled through this coming weekend & get the steering box in place so make sure everything fits nicely.
