any tips on welding rear renders on a 41 or 46-48 ford.

hello wanting to weld em on thinking round rod in the gap then fill , what is the best way to smooth these fenders out.. any pics? ideas..thx

 

I think the best option would be 19-20 ga. sheet metal, bridging the gap between the body and fenders. would give a better flow between the two and would not have to grind the rod down. probably the sheet metal would be better to weld rather than rod. I think Ron Koval did an article in Street Rodder a few years back using sheet metal strips.

 

here's a link from a week or so ago about the same subject, hope it helps. I agree with fordor, use steel to make a bridge between the fender ansd body. good luck

rear renders?

Scooby...is that YOU!?!?

 

The first thing that you would have to do is remove the fenders and sand blast the weld area.
Next, why would you want the fender flange on the fender to collect water and rot?, Remove it.
Next weld short tabs made out of 16 Ga. on the edge (1'"X1") and fit to the body side and tack on.

Check fit and procede to weld formed filler strips all along the gap.
Cool the welds (no more than 2" each at a time) with a air blow gun and alternate welds along the edge. Weld 100% without any gaps.

Grind and hammer out warped and high areas.
Most importaint! Prime and fill the gap on the underside with an autobody sealer to prevent water fron entering and causing bubbleing of the finish filler.

The 16Ga. metal provides a good heat sink so that you wont burn holes through the thin fender. keep the arc on the edge of the 16 Ga. and let the puddle flow over onto the fender. **** weld all the filler strips to each other, don't overlap.

I use .023 wire and some times use a continus series of short tacs, well fused to each other. (You can weld rust and air together this way (;-) )

Remember when grinding, you create more heat than welding, keep it cool.

 

two inch strips big enough to get the flow..

 

I built a 1947 Ford coupe and used the rods on the rear fenders they worked well for me. I cant remember if they were 3/8ts or 1/4inch rods use the ones that work the best. start weld on one end and then heat the rod to follow the fender it went smooth. braze or weld then use body filler.
