That's one happy looking Peter Miller..

Hi Richard, Nice cnc dude. I also made my own cnc machine a few years back and was really pleased with the result. OK it wasn't as fast as the commercial machines due to the small calibre lead screw but it worked - and it was a great project to do. I ended up selling it and then upgraded to a commercial machine which I have used a lot since. Nice to see someone else CNC'ing there own GTC - my thread is under the 2018 MB. I also scaled mine to 63" span and drew a kit in CAD, then machined the whole lot. I use Solid Edge for CAD, then Curve Cut for nesting and MACH 3 for the machine.

What a cracker Peter - another great design and you look very pleased too. Well done mate!
-
Wow - Not sure how I managed that?

True Tim - I'm sure there are better rants on here - I guess I have had time to process it all so my rants have faded out. However - the positive is I am building models again. I have even cajoled my 12 year old into making a flat plate delta design for a bit of fun. You must be nearing the maiden flight for your GTC?

Tim, Yes that was me - Not wanting to soil your thread with a rant I have answered your question on my GTC MB thread. Positive side is I'm back to building. Rob

Tim, To answer your question in your thread, it was me - I started in Jan 17 and made a bit of progress for 3 weeks. But that came to a grinding halt until last Jan 18 due the requirement to pack up the workshop to move, then we didn't - so unpacked it all. Then we found we needed to re-build part of my house as the builders had 'attached' the new steels to the old crumbling chimney with 4 x 2" bolts (!) without any chemical fixings, used dangerously below spec floor joists and generally left the house, mainly my son's bedroom, unsafe. Oh yeah I could pull 1 of said bolts out with my fingers while undoing another. Sorry I'm ranting a little. Now the house is nearly complete I have retuned to the multitude of projects in the workshop.

That's not a bad shout Peter - I've not used SC engines before so they are certainly in the mix. My other current thought is electric with the batteries in the nacelles - this would keep the wiring easier with less modification required. Have to admit I'm 60 elec / 40 IC which is a little scary as I consider myself an IC man.

Well I think the phrase I am looking for rhymes with clucking bell. One of the OS 32 engines I had intended to go in to my GTC has stripped the chrome piston liner and won't run. Oddly enough as it is out of production getting another is unlikely. It was fitted to another model (a scaled-up Tequila Sunrise another PM design) and it has struggled to start and didn't develop full power - then gave up the ghost. This is the second one of these that has done that. This leaves me with just one left. So...right in the middle of carving the cowls to fit OS 32s I now have to change tack - I'm starting to think electric but while I ponder and give the problem a huge dose of chin sctraching I will give the fuselage some attention. Tim, I always find I need something I 'should have bought ages ago' in every project. Only if I buy it I seldom need it again. Your GTC is looking great btw.

Sorry if I missed an earlier post, but is that film HK Pirate blue? You are nearly there Tim, makes me feel so far behind. Best Rob

Ace, I've not heard of that before so will try it when I get the chance - thanks. Sadly in this instance the sanding block (a Great Planes aluminium jobby) pierced the skin so I needed to apply some glue. With a light coat of filler I don't think it will show. Tim, Not sure if I can be of help for your cooling vent - I know there are others who have made suitable tips from soldering irons and there are smaller proprietary shoes but I guess if glue works then go for it. Alas not needed for IC as the cylinder head is in the airflow. Thanks for the vote of confidence Peter. Edited By Rob Ashley on 29/01/2018 14:45:33

I have also realised my photographic skills leave a lot to be desired!

Hi Tim, I did consider the split flaps/ailerons and also retracts having looked at yours, but in the end I decided to keep as close to the original as possible - save the size increase. I started by using PVA for the sheeting, but having discovered aliphatic (Titebond) I am a total convert. I love the stuff. I found on cold nights the PVA just wouldn't cure properly and left a white residue. My workshop was not then permanently heated only with a calor gas heater when I was in it. Also I think the Titebond grabs well and is much easier to sand. Had an 'oh bugger' moment last night after I dropped a sanding block onto the wing - it's made a dent so there's my first ding.....

Hi Greg, Glad to hear to repaired the GTC. I started mine over a year ago and for many reasons the build came to a grinding halt, but with the 2018 MB underway I am back at it, hoping to complete it before spring. I think I will keep a similar finish/covering design as Peter's too. Rob
-
Thanks chaps - I had better go get some. I appreciate I am one of a number of builders of this model so I know there will be much repetition. Anyhow I'm finding that doing this thread is keeping my motivation going, so hopefully I will finish this build. Tail feathers are ready for final sand and covering. When I cnc'd my kit a milled a tongue on the fin that slots into the horiz stab to ensure everything remains square. Also fitted the nacelles which didn't really need too much fettling. I think like most others who have scaled up I have opted for 1 servo per wing to allow for flaperons if required. Otherwise this will be as per Peter's plan.

Nicely done John! -
Hi Simon - nice job!
