Have two left.

5a I have CLIMBER

6D I have INCH

I can't give the clues because the answers have surplus (or missing) letters. I can only hope that a Genius solver takes pity on me.

5a climber seems ok - add ND to a seer to make a sender ( sounds like ascender, synonym for climber)

[roslyn251254]

6d Cinch would be "for sure" so I suppose "C" needs to be removed

[roslyn251254]

6d or perhaps MEAsure for the inch
I've got 16d but not sure where all the letters come from in it.

Thanks for the parsing. I'll go with what I had.

7 entries add a total of 16 letters, 4 entries subtract 8.

Hello keithsolver I wonder if you can help and explain a little further. I seem to have a few problems finding the missing letters in the clues, though I think I have completed the crossword correctly.
1. Is the 16d phrase one which describes the two positions of a switch?
2. If so my missing letters IM in 13d clue seem to be wrong as they do not cancel out.
3. I am still looking for the 7th clue with missing letters. I have F(4d), IM(13d), ID(20d), ASS(28ac), MEA(6d) and ND(5ac)
Would appreciate any hint you can give to correct me or help me along. Thankds in advance
