6 Steps to Mount the T-Tip
The shaft of the T-Tip has a small cylindrical head part and a long conical stem with grooves.
- The cylindrical part has a diameter, Ø = 4,0mm and serves as the bearing point.
- The conical stem with the grooves is mounted in the wood shaft with epoxy which secures the T-Tip shaft because of the interlocking of the grooves and the epoxy.
Thereby a secure binding of the T-Tip and wood shaft will be created.
1. A deep drill hole in the wood shaft
The depth of the drilling for the T-Tip aligns with the stems length. Limited by the specified weight of the applied materials (Stainless Steel, Brass, and Gunmetal Steel), the weight and design of the T-Tip result in a different stem length, that requires a different drilling depths in the wood shaft.
The T-Tips have the following stem lengths:
- 100grain Stainless Steel T-Tip = 25,0mm
- 125grain Stainless Steel = 25,0mm
- 100grain Gunmetal Steel T-Tip = 25,0mm
- 125grain Gunmetal Steel T-Tip = 24,5mm
- 100grain Brass T-Tip = 17,8mm
- 125grain Brass T-Tip = 17,1mm
These stem lengths can be used as recommended values for manufacture of the applied drilling depths.
The manufacture of a required boring depth can be achieved with an appropriate metal sleeve. The appropriate metal sleeve should be set on the drilling bit such that the drill depth is assured. These various metal sleeves are available from us.
The boring depth has an influence on the alignment (centering) of the T-Tips. If the boring depth in the wood shaft and the stem of the T-Tip conform, the opening of the boring in the shaft can be used for centering while inserting and setting the point.
Thereby the shaft of the T-Tip is supported twice while sitting in the boring.
2. Preperation of the wood shaft
The front end of the wood shaft should be sawn perpendicular to the long axis of the shaft.
- So that the central setup of the point can be assured.
- So that the point's base can be in contact in full with the perpendicular face of the shaft
Verify that on the wood shaft at the joint there is no splits or tear outs.
3. Preparation of the tool
- The appropriate metal sleeve for the depth of the boring and T-Tip is used and installed on the drill.
- The appropriate sleeve for the working of the shaft diameter is mounted.
- The drill machine as been fixed into the holder.
- Securely clamp Arrow-Fix's drill shaft into the drill chuck of the power drill
- Verify the drill machine is set to run clockwise/right.
- Wear safety gogggles.
- Set the drill machine for continuous running.
- Set the turning speed to a lower setting.
- DO NOT grip the turning Arrow-Fix!
4. Make the boring
- Hold the wood shaft with both hands and feed it into the sleeve of the turning Arrow-Fix.
- With moderate advance against the drill, press the shaft so that the drilling can begin.
- Arrow-Fix differs to conventional drilling procedures in that the work piece is fed into the stationary drill and not the drill into the work piece.
- As with conventional drilling procedures of a power drill, the chip removal would be encouraged with drilling in and out.
- The drilling procedure should continue until the shaft has reached the metal sleeve used to gauge the depth.
- Remove the wood sawdust from the drill hole.
5. Setup of the T-Tip for fixing
- Insert the appropriate T-Tip into the boring.
- Hold the shaft with both hands and with point set against a stiff surface such a wood board, you should press such that the last space between the point's shoulder is in complete contact with the shaft. Pay attention that the T-tip is pressed perpendicular to the axis so that the point can be centered.
- By hard wood, like Locust or similar, it is possible that the drilled depth may have to be increased with out the metal sleeve when the pressing of the point too difficult is. It is often enough to increase the depth by .1 mm. The reworking can be done successfully by hand without the drill machine.
6. T-Tip gluing
- Pull the T-Tip out of the boring of the wood shaft.
- Apply the Epoxy on the stem of the T-Tip and then insert it slowly into the boring.
- Ejected and overflowing Epoxy should be removed and verify that the point's shoulder butts against the wood shaft fully.
- Control that the T-Tip is setting in the center and make adjustments if necessary.
- Wrap the shaft with strand and cover it with Epoxy to improve the stability.
- Allow for the Epoxy to cure.
