That looks good Mike. 12g sounds good for all that woodwork.

Meanwhile I have been tissue covering. My least favourite job, or maybe next least after glazing. Always seems to be my time to spoil a perfectly good framework Embarrassed.

Tim - I have not thought much about the weight but you got me thinking about it. It is very fragile and so here is the overall weight to date. Don't know why my system has decided to post in a rotated format but here it is nevertheless.

There's a concise publication by Charles Mendenhall titled The Air Racer. I have a copy and will post it when I figure out how to post a PDF.

Interesting cookup subjects air racers 1920 - 1939.
Having worked on a formers and stringers, bubble canopy and wheel spats model Cosmic Wind 1948 US National Air Races winner, I long for something simpler to build.† No biplanes, spats, round fuselages.† Have gone through Wikipedia but did not find one I wanted to model.† I have a Curtis Robin kit that fits the simple to build criteria but no evidence it was ever an Air Racer,† Curtis CR3 looks good but a biplane.† Closest match to the criteria so far is the Heath Baby Bullet.† I did search to see if Gadfly by Sherman Gillespie was ever in an air race in England but no evidence it was.† Still looking for a slab sided† air racer† 1920 -1939.† †Smiley

I know itís a cliche and you canít tell without weighing it but it looks like a lovely light structure Smiley

Greetings All - Been gone for quite a while and spent the morning reading thru the postings that came up and all are looking very good. I've been working along some but needed to take some time out to regroup a bit, seems things come along in groups that take our time and attention, as Tom said, family first, hobby second or maybe third, anyway my brother passed away two weeks back and SIL's husband also passed three weeks back so we have been a bit distracted but are back on somewhat an even keel.
The Crosby has seen some progress and as I said, the fuselage went into the bin and brought out the fuselage frame and started again, even at that I had to eliminate the tail cone to get it to fit. I'll make that from a solid block and hollow it out to nearly nothing. Most of the major components are done and now for the detail stuff. Some of the formers were undersized to the point the stringers would not come anywhere close to fitting so need to build out some places to support the stringers. Will put in some plug in sockets in the wing for the detach landing gear, sand it a bit, vac a canopy and cover. More pics soon.

Due to the circumstances of covid and family isssues I'm extending the cookup through May.  I hope to be able to start my project soon.  Thanks for all who have continued work and I hope this doesn't discourage anyone from participating but encourages them to find a model plan and join us.  I commend those of you who are involved in the Nassise Cookup on HPA!  I am following that cookup with great interest!

Sorry to hear that youíve been unwell Tom; I hope things are improving now.

Iím continuing to inch forward with the Semiquaver. I have made a nose block. The bearing is just aluminium tube set at the plans suggested 3 deg right and 5 down. Then a tail skid from 1/64th ply. Not very detailed but Iím not aiming for super scale appearance.
Now I have started the undercarriage. The legs are some hard 1/16th balsa. In the photo the bottom piece of balsa is a simple jig to hold the legs square and at the correct angle while the spreader is glued on. The completed undercarriage will be fitted later on as the front legs fit to the fuse but the rear legs go on the lower wing. I have made sockets for the legs to go into rather than just glue it onto the tissue. Last photo is a set of bits for the wheels.

Looking fantastic.  I hope to start soon.  Been challenged with the Bronchitis and then my wife got sick and so we've been back and forth to the Dr's.  Too much time waiting in car from my perspective!  But much better now.  Thanks guys for carrying on!

I havenít done a lot more on the Semiquaver but in the interests of keeping things ticking over I have done the next best thing.....I took more pictures Smiley.

The things I have done are; adding hard points on the wings for the interplane struts; sheeting and sanding the bottom of the nose and the top of the deck between the nose and the cockpit; the last bit as a seat for the pylon which supports the top wing.
Everything so far weighs a smidge under 7.5g. That doesnít sound too bad if you say it quickly but when you realise I still have to make interplane struts, nose block and prop and wheels and undercarriage, then it all needs covering and finishing; I donít think itís going to be light  Embarrassed.

Hi Tim - Agree with your point about the short grain in the ribs. I tried using the lamination method but the form was the problem so I use two 1/32nd sheets laminated cross grain and sanded to 1/16th, helps a lot with the strength of the ribs and the internal brace of each rib goes a long way toward the overall strength. I usually renew my membership in the "Broken Stringers and Cross Members" club somewhere in the build, don't keep track of my fingers too well.
Mike
