The Glue Gun

I need to create internal fillets against the fins between the motor Mount and the Air-frame. The gap is very small – ~12 mm. So I’ve purchased some 5 mm diameter tubing with some 50 mm syringes to get the glue down there. I have used some thin doweling with masking tape to help direct the end of the tube to where the glue needs to go. Below are a few pictures:-

We have marks every 2 cm. Each cm corresponds to approximately 1 cubic cm of araldite.

We will only need about 21 cubic cm of Aradite per fillet.

The process will be:-

  1. Suck up 25 cubic cm of Araldite into the gun
  2. Clean end
  3. Insert gun up to the ‘zero’ mark
  4. Push 1 cubic cm of araldite in
  5. Withdraw 1 notch

Repeat step  4,5 will tall the way out
