We have a few more updates just to make sure everyone knows that I’m not dead. I have actually been very busy on this project, albeit just on the permit side of things. I am actually very seriously considering using my newly refurbished Permit hull, making a mold and making a new Jack plug from that mold…lots of work yes, but I love the Permit boats so much that I just have to do them over and over again. In my case it is kind of like having to learn to walk after running first…maybe I am the Forest Gump of the model world he-he. Anyhow, I want them to be completely consistent with each other, other than the modifications, and this is the only true way to do it.
Anyways, here is some small tidbits on flush mounting the MBT into the hull. This time around I am going more scale than the previous hull. I don’t think it will look as cool, but it will be more scale.
The Forstner drill bit is the key here for digging out the material that needs to come out, in an extremely clean fashion. They are designed specifically to leave a flat surface as opposed to the 30 degree tapered cut that a normal bit would leave. A good example of their usage is the mounting holes on European style kitchen cabinet doors of which 30mm is the standard size. I am not sure where in the USA that they would be readily available in all sizes, but here in Canada they can be bought at most places that have a good selection of cabinet making tools. The best place for me is the House Of Tools, the bits are cheap and come in almost any size in increments to the nearest 1/32nd of an inch.
As shown in the picture, the bit has a small pilot cut on the end to keep the whole thing on track when drilling. I am going to fill the hole left by this because it will be rather unsightly for the finished product here. Also note the center punch in the MBT to get things started
To remove the material on the rounded surface I use slow speed on the drill and then rock my drill from side to side ensuring the amount removed. It also depends on the material you are removing, in this case my 2-part vinyl ester primer is so hard that it “shaves” away, it kind of reminds me of drilling into steel when you have a nice sharp bit.
As shown in the pics the outside scribe really brings out the detail in the MBT.
With the hole filled
Very cool indeed,
