Hello,
I have started working on the new scope
the one thing that is worrying me is this tube.
the lens screws on fine right now but the dent sticks into the light path.
what is the best way to handle this ?
Should I cut the dent out?
should I get a tube expander?
what do you guys think
Thanks Paul

Paul....If the tubes weren't so heavy gauged I'd be tempted to remove the lens and replace the cell back in place and tap the tube out with a small ballpeen hammer. You have to be carefull of the fine threads taking the cell back off again though. Therefore if you don't have access to a tube expander I'd go to a place that repairs brass musical instruments and they can make dents disappear at a reasonable cost. ;) ;) Mike

Paul,

Mike's advice is very good. If you don't have a tube expander or access to one, take it to an instrument repair shop. You may also have to take it to a machinist afterwards to clean up the threads -- however, there is a danger in this because you could possibly have the finish damaged. If it's damaged already it's not a big deal; but if it's not there's little sense in damaging it needlessly.

Paul,
I had to straighten a similar (self-klutz-inflicted)
dent in the edge of a scope.. Wrap a broomhandle or 1" dowel with several thicknesses of felt or a towel, and lay a towel or mat on a hard surface. Carefully insert the dowle part way and roll out the dent... It worked pretty well for me, but do be careful with that threading!
Beautiful scope, and dandy luck you had!
Congratulations!
Carol

Hello,
Thanks for the advice.
I think i will try to rent/buy a tube expander
If i can't I will try to find a repair shop
I am afraid to try the broom handle method myself
but if all else fails I will try it
Thanks again everyone
I'll let you know how it works out
Paul

Paul,

Personally I think the metal in that Tasco is too strong for the broom-handle method. A pipe, on the other hand, might work...
