On building & the unexpected time / $ it may take;
About 15 years ago, I purchased an old ATEC Zephyr - Great aircraft!
She was flyable but looked a little care worn. As my knowledge of the aircraft increased, it turned out that various bits were well past the factory recommended "time" in service.
I decided to do a complete in/out make over/refurbish, on the bird.
I estimated 1-2 months & about $10,000 AU.
About this time, I retired, so was able to devote up to 7 days /week and anything from 6 - 12 hrs + /day. I guess I averaged at least 5 + day's/week and likly 8 +hrs /day
It took all of 12 months and probably $15,000 AU.
Some of the unexpected factors were:
Cost of importing the Stewart paint & fabric system from the US. Australian importing add-ons can be a bit of a shocker
All the little essential hard to budget for bits & pieces eg special temperature controlled iron for shrinking the fabric, quantity of sandpaper, etc
The shear length of time / hard graft, to remove fabric & paint.
The learning curve required to replace the fabric.
Purchase of a high volume, Honda powered, compressor, to suit the Stewart application system.
Built a temporary spray booth with forced, filtered, heated, through air, ventilation and wall / ceiling strip lighting
PPE for toxic dust & paint spray
I already had the 4 kva generator to power tools, lights, fan & heating
Etc, etc.
The reward ;
The project got me through the potential for post retirement blues .
The satisfaction in the remade/new aircraft, that was now safe (particularly the fabric) and flying better than before.
If I had moved straight to another (similar) project, within the next 1-2 years, I could probably do it in 1/2 the time (skilled up) and now that I have invested in various tools, a few $K less.
The take home message;
Get some advice on exactly how long it will take to build or refurbish.
Ask & cost (if you don't have them) what tools will be required.
Budget for the project PLUS a significant factor for additional consumable etc
Think carefully about the estimated time, against your other commitments.
