Hi Arty, and a warm welcome to the forum. Its always nice to have another Scotty owner on board.
Re: your query; the answer is yes you can, but you will have to remove the soleplate assembly (bottom blade holder) from the machine, remove the rivets and existing bottom blade.
You will need to drill and tap the original rivet holes in the soleplate to 5/16 Whitworth and purchase a set of five (5), 5/16 whit x 1/2" long countersunk metal thread blade screws. If the bottom blade is still serviceable, you will need to drill and countersink its holes accordingly, or if the blade is unserviceable purchase a new one which comes pre-drilled and countersunk already.
Arty, this would be a good time to remove the cylinder reel, check and replace the bearings if necessary, have the reel sharpened and the bottom blade finish ground to suit the sharpened cylinder. If you wanted, the engineer who spin-grinds your reel, could do the modifications to your soleplate for you.
Once again Arty,
