Wheels for drill-gearboxes?

[harry hills]

+1 for non heat-pressing. I did some like that yesterday and it came out so much better. Not bearingboys wheels, but nylon wheels/hubs still.





That was the 3/8" UNF brass nut connector things from eBay (I'd bored them out to 10mm because I needed that) shoved into a 14mm bore. The nuts are about 15mm or so.

[plargen]

the steel ones tend to be about 15mm edge to edge and 13 on the flat ive even found some with a tapered

What's the grip on the nut like Harry? better than heat pressing? It certainly looks neater from the pictures.

[harry hills]

Probably not noticeably stronger/weaker. Just much easier to get straight which is very much a good thing.

[plargen]

ive gotta manage it with some 1/2 unf nuts on some bearingboy wheels for the new Night fury

[harry hills]

What drills have a 1/2" UNF output. I ask as I found a box of 1/2" UNF taps today and less messing about with nuts and hubs would be a cool thing.

[plargen]

there makita 2 speed drills, i was gonna use them for the dog style bot but after the damage caused to NF i realised it would never survive so their going into the new hdpe NF2 so 15mph and twice the nm torque that the old bot had

thanks for the links and the info folks saved me a tone of head scratching indecently will those brass inserts fit on these motors ?

little of topic i know but figured i might aswell ask

[mrsam]

Yes they will as the Gimsons have the same 3/8 unf thread output shaft as a normal drill motor

Rory, not a bad find
The shore value is a little high. The preferred orange or blue ones from banebots are either 40 or 50 shore

Maybe their nylon wheels and bike tread http://www.bilcastors.co.uk/solid-wh...s-c-54_56.html

Have a look at Rory's post on different wheels

[daveimi]

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:

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.
