Jart from scratch

<< < (5/6) > >>

billscottni:
One of my New Years resolutions, apart from losing weight (Doctors orders!), is to get my ass in gear on the builds I have on the boards.

Ordered some bits I need for both the KA-3 and the SU25, (mainly brass tube, piano wire and carbon tube/rod).

Then I got on with glassing the lost foam fuselage. Attached is a pic of the fuz with the first layer of light glass added. Tomorrow I will put on some carbon reinforcement, (around the wing mount and LE of the fin).

joe:
Hi Bill. Good to see the jart back on the building board. What weight and how many layers are you going for?

billscottni:
Not aiming for any particular weight Joe. More concerned with durability.

That first layer is a light cloth (50g/m), easier to work with on the smooth tape surface. I'm then planning on a length of 50mm carbon tape along the bottom from nose to tail and layer of the same tape on the LE of the fin. Possibly a criss cross pattern of Carbon tow nose to tail to give an overall strength. Then at least 2 layers (maybe 3) of a heavier cloth (100g/m), finishing off with another layer of the 50g/m.

That's the current plan, but I will adjust if the strength doesn't seem too good. Hope to get the carbon and one layer of 100g/m done tomorrow and then cut tails for it.

billscottni:
Not as much done as I'd hoped today.  :?

Got the carbon reinforcement along the bottom of the fuz and LE of the fin done. Carbon reinforcing and another layer of glass (100g/m) on the hatch, which doubles as a wing cover too. (see the second pic in my first post).

Sanding down of the first layer of glass took longer than anticipated and I was a lazy bugger and had a lie in!! :!:

billscottni:
As I said in my Fiu thread, a productive weekend. Spent today sanding the final layer of "heavy" cloth in the Jart fuz. Resorting to the angle grinder on a couple of stubborn spots to remove epoxy runs. Carbon tape aling the bottom and fin LE. Carbon tow reinforcement in a couple of strategic places. One layer of "light" cloth now needed to finish it off before a final sanding and shooting primer/filler on it.
