Husqvarna Mag Chainsaw Body Repair

[Kelly Jackson]

We appreciate some information on Repair Mag Alloy Cranks and Top Covers on Older Husky 65L Tomos, L65 and 650, 77 Model Saws. Have a couple of the Mag Alloy Cast Parts which have had some wear from either General Usage, being Rubbed against a Harder Material and have some Indents due to Wear. I am Restoring these Old Saws and Plan to Powder Coat after I Can Figure out if I should just use some type of Automotive Body Filler to Fill in Worn Mag Alloy Castings being Top Covers & Crank Bodies or use some type of JB Weld or Liquid Epoxy 2 Part Compound and then Sand or Lightly Grind/File. Aslo, If a Etching Primer would be Required before Powder Coating or Painting

powder will take to plastic fillers, if not too thick
under 1/8" was our guideline on boat parts

I've had pretty good outcomes using JB Weld to fill cracks, scuffs, and affix non-structural pieces of case. Prep and Rough the Mg properly and it seems to adhere reasonably well, then as you describe it's quite sandable/contourable and after painting will certainly be a less noticeable repair. That would be my choice for performing the resto work you're talking about.
