Hi Jeff
Why not sell your 8’ diameter curves they are going for near $100 for 12 used ones then you could buy longer straight pieces and with longer straight pieces have less rail joints to deal with if you are track powered.
I used a dual railbender once and it worked really nice until I got to the ends of the track and the curving process kind of stopped on the last inch or so. The more joints you have the rougher your track will be.
When using a dual rail bender the best way is to add another section of track with rail clamps
and that wont happen, single rail benders in my opinion are mostly useless. Borrow a dual rail
bender from a club member or a friend and straightening the track is simple.
My rail bender is a Train Li version and works great. RLD Hobbies makes a nice one as well.
