Gerald,
I've been in the same situation. The best advise I can give is not to build on beat up military actions. You CAN make a sow's ear into a silk purse, but it's much easier to start out with a good used Remington, Winchester, etc. It's just like stocks - the labor is the same whether it's nice wood or firewood, but the end result is far better with nice wood.
I found a commercial FN mauser (a Marlin-barreled rifle in 243 for $250) to build my 35 whelen. The action is much better than miltary, the bolt handle needed no work, and the trigger & stock were useable. A new barrel, side-swing safety, and refinishing/recheckering the stock gave me a nice rifle. The stock is straight grain walnut, but an ebony fore end tip & grip cap, with a black decelerator .6" pad, it's nice looking.
Regards, Ron
