Re: 9.7mm hand reamer

Mike, I didn't want to bore you - ouch!! - with the details but I'm working in a very confined space changing a fastener from a high tolerance 3/8" AN176 to 10mm ground shouldered bolt; not a wing pin exactly but something similar. Hand reaming when fitting the 3/8" fasteners worked well using a rat...

Re: 9.7mm hand reamer

Thanks for the suggestion - one of my first searches actually.
Needed to have a bespoke reamer made for me - plenty available off the shelf from China etc but didn't want the obvious risks to say nothing about keeping my purchases from UK sources where possible.

Re: Performance reduction chart

Mark, many thanks or this - excellent sleuthing by the way! You are right in saying its about density altitude but only partly! 'Standard height' is the arithmetic mean of a corrected altimeter height {or mb setting, instrument error etc} and a 'full density height'. In essence its a practical fudge...

Performance reduction chart

I have just bought a copy of Flight testing of production aircraft by JA Crosby-Warren, Pitman 1943 Fig 1 in appendix A is missing and I was wondering whether anyone else who had a copy of this book could scan it for me? The text refers to fig 1 as a copy of Air Diagram No 1077 published by HMSO but...

Re: Vortex generators from STOLSPEED

Thank you Trev that is very useful feedback.
I have ordered a kit just in case I may need it.
And sure, any flight testing will need to be disciplined and documented (even on an SSDR)

Re: Two of Bob Whittier's articles in 1962 Sport avaiation W

Hi Ian, once again my thanks for this. I had a bit of a clear out a year or so ago and must have thrown away the article I am looking for - so its all my fault! However, I have now found the information I was after in 4-8 of Hoerner's Fluid dynamic lift.I was chasing up the article on behalf of a fr...

Re: Two of Bob Whittier's articles in 1962 Sport avaiation W

Hi Ian, thanks for your help. Yep 1962 was only a guess; I had tried a google search and came up with the above issues of Sport Aviation as likely to have the article I need - but got it wrong! Bob's articles were always well informed and well written. They spanned many areas as I recall, from aerod...

Re: Two of Bob Whittier's articles in 1962 Sport avaiation W

Hi Ian, thanks so much! The Bob Whittier article on effects on drag of fabric sag, rib stitching, joints in overlapping plates, protruding rivets etc is really useful and informative. Truth is I'm after an article that I can just about recall, by Bob Whittier, who discusses how the low turbulence NA...

Potting compound or encapsulant

Suggestions please for where I can buy a small amount to keep the moisture out of VHF antenna connection (ring terminals to a Bob Archer folded up dipole ie dyslectic swastika type). Many thanks in advance
