I'm looking for some easy to use and inexpensive molding compound to make some molds of my T140,T120 & TR6/7 ports. An internet search reveals several different 2 part compounds, different ratios and prices that weren't as low as I was hoping for and product specifics for the hardness of the cured compound that I don't relate to with my limited knowledge of rubber, urethanes etc. Any recommendations for a port molding compound? Thanks, Mark

Go to a craft store and get liquid latex. I used it to make a mold of the ports and chamber of the triple. Brush in layers then add cloth to give it body, then brush more in on the cloth. Peel it out when it dries.

You can use urethanes but need to apply a non-stick coating so you can get it out. And be careful not to get it locked in by the throat. The latex is flexible enough to work it out through the chamber.

Silicon molding rubber usually you just spray the port with silicon. Before tipping it in. Not enough hardener is messy and annoying. Put the valve in If you are just after port shape. I know you can mold the whole deal but the chamber is visible anyway. The port is difficult to see the shape and a mold is easily seen. If you use a temporary loose guide for porting, it can be pulled out to aid removing the cured plug. Though it should come out the valve side anyway.
