Hi all
Not had any chance any modelling in the last few weeks and the project to make myself a stooge is on hold until I get the heavy camera tripod back off the eldest who has mounted some big binocs on it for star gazing. However today I picked up a Leytool hand drill for a quid at a carboot



It took a couple of hours to de rust and clean all the glue and paint splashes off but the mechanism works well and it should make a good basis for a winder for the boys planes. It will keep them off my beloved KP winder anyway.

I appreciate that the chuck on its own wont be secure enough to hold the crochet hook in place. I don't have welding gear so am thinking of pinning the hook in the central hole in the spindle and using the outside of the chuck to stop the pins coming out.

That looks very sturdy Tom. Nice find. You might want to make a "counter" for your unit.
Also consider making a "blast tube" for winding the rubber so you don't damage your model if the ruber breaks.

How about using a counter from a jump rope, like below...?....they come extremely cheap, and I assume they are non-friction easy spinning....

I was browsing the Hobby King site and found this:

That Leytool hand drill makes a VERY good winder for rubber jobs.

I have two of them and have used them for many years winding large.....16 strands of quarter rubber, down to small stuff.

I have extended the handle and have taken off the chuck, drilled a 1/8th hole through the threaded part and put a 1/8th piano wire hook into it for safety rather than a hook coming out of the chuck.

A good idea is to pull it apart and grease it inside as well.

Cheers for those thoughts folks.

We got one of those cheep I electric winders and on a couple of rechargeable batteries it works surprisingly well, on the sub 24 inchers we fly in the park we can get 250 to 300 turns on for trimming flights quite quickly. Another favourite is a bent nail though a cork with a slot the size and shape of the props hub, held in the chuck of my beloved Makita 18 watt drill. It's like super fast finger winding. For the lads Cloud Tramps I finger wind the first one, memorise the number and thickness of the knots at the required number of turns then for the rest of the flights I just wedge the cork on the prop, squeeze the trigger and switch off when the knots look right. Fitting a counter would be better of course

What sort of grease should I be using? All I have in is graphite grease in some SLR cleaning kits!

OK here's were I show my ignorance, how exactly do you use a blast tube? Stretch winding does scare me!

I think, with plastic gears, you'd better play on the safe side, as several (particularily petroleum based) greases don't do the plastic any good in the long run....
I would try something as simple as ordinary soap, or similar...

My 2 C's....

Just found a pic of one of my winders.

Blast tube I always use but hard to describe......I'll have a go if no one else comes in.

Should think any old grease would do, as the Leytool has metal gears..........I have a tub of motor grease here and another tub of marine grease.
