Hi Jermey.

Professor Motor has 8-units in stock.

https://www.professormotor.com/product-p/hud103100.htm

Used ones are like hen's teeth... chicken lips... snakes armpits... goose gills... fish feathers... etc.

Anyone that finally breaks down and buys one? Uses it. Anyone that uses it, usually won't part with it. They are that good.

One thing to be aware of with the Hudy. - The drive shaft to which you attach the wheels, is stated as being 3/32 inch which is equal to 2.38125 mm

- It isn't.
If it was, an NSR wheel with a 2.37mm hole would not fit on the axle, and the common 2.38mm wheels of different brands would be somewhere between press on and sodded tight.
The 2.38mm aren't tight, they have a bit of play.
The 2.37mm NSR also slide on easily with a little less play.
I estimate the diameter of the shaft end where you mount the wheel, to be around 2.36mm

I bought 2 more original axles for mine, assuming the original was worn - It wasn't.
All three were the same, and my multiple emails to Hudy went unanswered.
I had a thread about this issue on SCI forum a few years back. I received mixed answers, but the most credible were from a couple of car builders I knew and respected, who said that they had noted the same.
One had put up with it as being "near enough and unavoidable", the other had replaced the original hudy axle with one he made himself, by turning down one end of some 3mm stainless steel stock.
By coincidence, Hudy and NSR used identical diameter ball-races for the main drive shaft in their lathes, which have the wheel mount as a smaller diameter at the end - that is about 2.97mm as best I could tell, because I had to polish down some 3mm myself with sandpaper in my lathe to get it to slide into either.

SO I made up 3 axles for my Hudy and my NSR, all to fit those 2.97mm ball-races, with 2.38mm "stubs" at the end. For one I turned down 3mm stainless, for the others I (possibly getting lucky on lathe runout error), drilled out some 3mm brass tube to 3/32nd hole diameter, then rammed a Slot.it axle up it with my lathe spinning. Finishing off by polishing that brass outer tube until it would fit into both the NSR and Hudy lathe drive post bearings.

So depending upon how fussy you are with your tyre trueing, you may need to do the something similar.
-Unless of course, Hudy have changed something in the last 7 years or so, but I doubt it.

A short fix alternative, is to coat the original axle with superglue or nail varnish, and polish that new surface coating until the chosen wheels slide onto the axle but don't have any "wobble-play"

I bought a tire truer because my cars used to vibrate as they picked up speed due to out of round tires. The faster the cars were crazy to drive.

I looked at the entire market before buying a truer. ScaleAuto, Razor, etc. The Hudy is not perfect. Nothing on this earth is. But it's way better than pretty much anything else out there.

How much vibration does a 100th of a mm deviation on the truing axle create? Not enough to worry about in my opinion. My fastest cars run smoother than peach fuzz after using the Hudy. I'm not asking my tire truer for perfection. I just want smoother running cars. Mission accomplished as far as I'm concerned.

I highly recommend the Hudy tire truer, and would gladly buy another. Not one of my cars has a vibration problem anymore. I love my Hudy.

Sometimes we need to step back and ask "Are we being too fussy?".

I win races because of my Hudy. I'm a super happy Hudy customer. Thumbup

I use mine, I use it a lot. I took a lot of my old 1/24 foam tires and ground them down for the WOMPS, it was like having brand new tires.

I also took an old 5-40 threaded axle and had one end machined down to fit into the truer so then I was able to true the tires on all of my old 60's cars.

Great tool I wish I had purchased mine sooner.

Hi Jeremy,

Getting back to the topic at hand. Trying to help you locate a Hudy tire truer.

Electric Dreams also has them in stock.

Try SCD - the BSCRA supplier will have them or know of a second-hand one: http://www.chaskeelingscd.co.uk/hudy.htm

Could also try the local BSCRA clubs - Oli Abbott at South Downs (Barnham) or Roedale (Brighton).

RE: Hudy Tyre Truer 3100 - BAracer - 1st-Feb-21

Nice surprise to find all these responses when I woke up this morning!

Yes, I have seen they are readily available in the USA.

Ah, I will ask SCD whether there are any in the UK.

Loco...I thought buying a Hudy would be the end of all my problems!

Check with Andy Browne Searle as well. (AB SLotsport)

I had Andy make up some replacement spindles - so I now have accurate 2.37mm, 1/8th Threaded and 3/32nd and yes I agree - would never part with mine Bigsmile

I would also suggest - if you are using MAINLY modern type cars - look at Tyre Razor as you can do both rears or fronts at the same time. (but not a cheap unit)
