Universal Drill Guide with tools for Moki and Valach
Moki and Valach Universal Drill Guide with tools
This CAD designed and CNC milled drill guide is the only one to match the Moki engines from 100BVT to S400 all in one as well as match all of the Valach engines up to the Valach 420.
These are a unique design and are a step above your usual drill guides, a lot of experience went into these.
He is what you get:
A 5.2mm drill bit
A6.2mm drill bit
A 5.2mm torsion pin
A 6.2mm torsion pin
A 10mm to 12mm adapter sleeve should you need to drill a 12mm propshaft prop
Here is how it works:
You will notice right away how thin this guide is. That is intended. When we drill we do not ruin the pattern due to the guide not being thick enough, we get bad results due to the pattern drifting when we travel the bit from one hole to the next.
With thick drill guides you will not notice until the damage is done. With the Aeroscale guide you can always see the bottom of the guide, you can always check alignment before you tap the next hole.
- Identify the 6 hole pattern that you want to use and mark the six holes using a paint marker with a color of your choice
- Place the drill guide on the back of the propeller, making sure that you use a drill press, making sure that your drill table is 100% level and clear of shavings.
- Use the drills we provided you with. They are a hair oversized for a reason. Wood is organic and wills seize back up after you drilled. And it tends to swell and shrink with humidity changes.
- Now TAP the first hole. Do NOT drill all the way, just tap it deep enough for later and for the torsion pin to be able to drop and grab
- Insert pin in your 1st hole
- Tap the next 5 hole, checking alignment every time
- Now remove the drill guide and now drill all 6 holes. When you drill them do NOT drill in one swift motion. Instead go at it like a Woodpecker. Drill a bit, release and allow the drill to exit the hole, getting rig of shavings. Make sure NO shavings end up under your prop as otherwise the drill would not travel through the propeller at a perfect angle! Now drop in for the next go.
You will most likely end up tapping/pecking/hammering at it 8 to 12 times until the drill made its way all the way through the prop.
- Now flip the prop over, get rid of all shavings and clean up all 6 hole from the front.
- Now comes the most important 2 steps. Flip the prop again so that the back is facing you. Let the drill run and grab the prop with both hands. Stand up and pump the running drill through all 6 holes. You will find that more and more tiny shavings will rain down until the 6 holes have almost no friction and feel clean.
- Now allow the prop to slightly "wobble" whilst you pump and and down. You want to create a very small "hourglass" cross section of your drill hole. If you can imagine you will end up with two slightly opened up entry holes on top and bottom whilst the center of the hole remains at its original diameter.
Your prop should now fit perfectly first try and will never "cease" due to humidity to where you can no longer install it when needed.
