Trimming 200pds Draw tube

[bottletopburly]

I have ordered a washer from Lasermaster 220mm in dia with an inner dia of 188 mm 1mm thick  to mask primary clips ,next is to trim draw tube which inrudes into ota 25mm ,a quick measure the max intrusion would be approx 6mm so 19mm to trim off the End does that seem about right to others that have trimmed the Draw tube .

Does the drawtube block any light to the mirror's full aperture when the telescope is focused?

Protrusion inside the main tube [at full inward travel] hardly matters if it is never seen by the mirror in normal use.

Yes for astrophotography not visual ,hence masking the clips
