Wheels for drill-gearboxes?

[shakesc]

Have a look at Rory's post on different wheels

Oh my god thanku sooo much for the info on hammering rather than melting!!!!!

You have no idea how much this has simplified my life! Every year I come across some tiny bit of info that revolutionises the way I do something. Well that's it for this year!

Hi all, new to the forum, hoping this gets a response as this thread has been inactive for 18 months!! Started buying parts for my first featherweight build, got some drills with the standard 3/8 drive shafts...but...

Simple n00bish question, will these:

Be able to to fit into these? (via a hammer)

Hi Ollie, and welcome!

It's been a while since I've tried to fit UNF nuts into wheels, and I've never tried it with those particular wheels, but I don't think they will fit as they are. You may need to either heat up the UNF nut with something substantial, like a blowtorch, and press them in (with the heat melting the plastic around the nut, and which will harden when it cools) or drill out the hole in the middle of the wheel to a more suitable diameter and then press (via a hammer) the nuts in that way. You should be able to do this second method without having to heat the nuts up if you get the hole size correct.

Can't offer much more than that I'm afraid. At about £2.50 a wheel it might be worth buying a few spares though just incase the first one or two attempts go slightly skewed (don't worry if they do, all part of the learning process )

Thanks Jamie.

I figured they might need a little 'persuasion' in some form. This will be a very basic build as I have limited access to tools, but yea I'm thinking as they are cheap, and I won't be entering this FW into any comps, it won't matter too much on performance in the end.

Should do. I would recommend drilling out the centre to match the distance across the flats of the nut (perhaps just shy of it by 0.5mm) and then heat up the nut and press it in. If you have a large 60w plus soldering iron this should heat up to the ideal temperature. If not then a blue flame lighter (few quid on ebay) will do the job too. Just make sure to do it somewhere well ventilated and do not touch the nut when it's hot (seems simple but i've burned myself a good few times doing similar things).

These work and are cheap!

Ok guys thanks for the responses. I've ordered some wheels off ebay today that are the same specs as these, 4 for £8... went to my local B&Q, didn't sell grub screws I need for the drill motors (solved now on ebay too) just need to order the connectors!

Waiting for DX6i to arrive, got a receiver today.

Okay unfortunately it seems the 3/8 unf adapters are way too wide to fit in the wheels I have... darn...

[typhoon_driver]

Cut them down to size with a hacksaw if you already have them. I would then recommend threading them on from the other end as the thread will likely get a bit damaged during the sawing process.
