Screwdriver type manufacture
Screwdriver type manufacture
(OP)
Hi,
I have a question regarding fitting a steel rod into a plastic handle.
For instance, if you was making a prototype of say a screwdriver, how would you connect the metal driver to the handle? I am hoping to not have to commit to tooling cost just yet so looking for a simple solution for a prototype. Obviously bearing in mind it needs to drive in screw etc. so must not come loose once fitted?
Any advice much appreciated.
Thanks.

Seems a very basic question??
Remember - More details = better answers

But if it's a normal size, and a prototype, I would suggest drilling and putting in one or two cross pieces to hold the handle.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

You might also cast the plastic handle onto the cooler steel blade, so that the plastic would shrink to the roughened blade shank.

Watch Forged in Fire. This is on Spike TV, but episodes are up on YouTube. They are making all sorts of fancy combat knives, which are way more interesting than screwdrivers, but they do have to attach handles.

ASME B107.600 SCREWDRIVERS AND SCREWDRIVER BITS
This is the 'big kahuna spec' for everything screwdriver and SD-bits... with exception of a few standards for screw-drive recesses/tool-tips typically used in aerospace.
Prior specs [CX'd]...
MIL-B-9946 BITS, SCREWDRIVER, GENERAL SPECIFICATION FOR
MIL-B-9946/1 THRU /20, BIT, SCREWDRIVER,... ...
MIL-B-85643 BITS, SCREWDRIVER, RIBBED, GENERAL SPECIFICATION FOR
MIL-B-85643/1 THRU /5 BIT, SCREWDRIVER,... ..., RIBBED,...
2. Another idea for a 'simple prototype screwdriver'...
Get a short section of PVC pipe ~1.00--1.25-OD and the glue-on plastic seal-caps, PVC cement, generic 2-part epoxy resin... and alcohol or acetone and clean cotton cloths.
Drill hole in one end-cap, on-center, for inserting the screwdriver shank; and a 'hole-start' in the interior/center of the second cap [for 'blank-end' of screwdriver shank to 'set-into'].
Clean interior surfaces of the plastic parts [tube/caps] 'break-water quality'.
Cement-on the end-cap with drill-start.
Grit-blast screwdriver shank to attain 'bright metal' finish.
Insert drive-shank thru the hole in the remaining end-cap.
Pot-fill the capped-off tube section [~90%?] with 2-part epoxy resin.
Insert The screwdriver shank into the epoxy resin until it seats in the 'drill-start'; then cement the end cap in-position. OK to add/remove epoxy just before this step.
Fillet around the shank/cap [exterior] with excess epoxy resin.
Might consider coating the 'handle' with PLASTISOL colored-coating for a 'softer feel'.

I believe this is the ~ $10 dollar solution he was referring to.

Eminently suitable for a prototype.
When production begins -
Provide a 6 in 1 screwdriver with bits
Glue your driver into a commercial handle and send me all the extra bits.
RE: Screwdriver type manufacture
maybe sell only your bits (that fit a universal screwdriver) ?

Here is a cool concept.
