I decided to do a quick post on creating the Radiator insert (Part 4A) and the radiator vanes (Part 4B). I knew that I needed to make the vanes to fit the insert part but was not sure how to proceed. Thinking about it I came up with the following solution (I’m sure there are more elegant ways to do this, but it worked for me, and I still have all 10 digits)

Create Part 4A by milling the stock to the correct thickness and make it oversize so that working with it is safe. I used painters tape and spray adhesive to put the template on the stock. Cut to oversize on the bandsaw and then sand to size and shape.


Select the stock for the vanes (Part 4B) making sure that there is sufficient thickness to accommodate the next steps

Attach the vane stock to a larger piece of material with double stick tape. This will provide a safe way to cut the vanes on the bandsaw.

Using a compass, scribe the vane outer and inner dimension on the stock.

cut the outer radius oversize and sand to final dimension:

Repeat by cutting the inner radius and sand to final shape and thickness.

Measure the 2.5mm thickness of the vanes and set the bandsaw fence to that dimension. Use 1/4” MDF or ply or hard board to create a zero clearance table insert.

With the concave side down, push the vane blank through the cut. repeat until you have the needed number of vane blanks

Sand the pieces if needed and apply to Part 4A. I start with the one in the middle and use the other blanks as spacers being careful not to glue the spacer in. I use a medium CA for this particular construction.

Glue all the vanes (Part 4B) on the insert (Part A) and then sand to final size and shape.

After this is completed and dry fit into Part 4C, any additional sanding adjustment of the shape can be one for a perfect fit.

I hope this helps anyone making this particular plan.

Today I start fabricating the tires, rims, and spokes. More to follow.

Regards,
Dave

Thanks Jan. Once the process is thought out, it all makes sense but initially it’s a bit overwhelming. The piece in the blog was actually a trial run before making the actual final part.

Looks like you nailed it Dave, I had forgotten about using hardboard for a zero clearance. Some time ago I had a piece with multiple cuts along the sides for quick setup on the table saw.
