After the radiator was glued to the engine block

Now to round the bonnet corners. I could either sand them round or I could use the round over on the router table. This last option is a bit more risky ito tear out. Despite that I decided to go the router route, but there was a problem. I still need to make one of those fancy router table fences where the gap for the router bit is adjustable. The present fence’s gap is a bit big for the size of the engine.

So I made a temporary fence with a smaller gap that was stuck to the regular fence with double sided tape.

Now I can route the corners without the work piece twisting into the bit.

After sanding

Now the dowels for durability
I used my dowel maker to accurately size the dowel. Store bought dowels are never round or precise. This jig makes the dowels exactly the size and round.

Exactly 5mm

Dowels inserted

and smoothed

Now for the radiator cap

Now for the center line bonnet/hood hinge
3mm insert cut using my Thin Strip Ripping jig

Cut to size

And inserted

Engine ready to be installed

Thanks for watching

Basically it is just a piece of steel plate / flatbar with different size holes.
I posted a project with my version no 1.
The one I showed in this blog is version 2

It is a quick project and after I made it, I wondered WHY I had not made one earlier.

I drilled holes from 3mm to 8mm and cut slots with my angle grinder to give it some cutting edges. I used a thin kerf steel disk. It works without the slots also. In some of the vids I saw for this idea the dowel is just hammered through. I found that the drill works better though, especially on the thinner dowels.

I use it to size commercial dowels and also make my own dowels. This gives you the ability to use hard wood for stronger dowels. I start with a square that is bigger than the size of the dowel I want and work it progressively down to the final size. It is best not to skip a size.

Great info George
And thanks.

On your other post jakeprater made some more helpful comments.

“I learned this trick from one of Izzy Swans YouTube videos. I ve done it with square stock in red Oak, alder, and Pine, in about 24 inch lengths. Any longer than that and I couldn t apply enough pressure without the piece bowing pretty badly. All I have to do is shave the end of the stock to fit the drilled hole to get it started, then just consistent pressure and feed rate to get some good dowels. I ve done up to 1/2”dowels this way, I haven t had a drill big enough to try anything larger.”

It’s sad when such great info gets last in all the other great info on LJ’s.

And thanks for your HowTo’s there’s always something to be learned by seeing things from so many different prospectives.
