Geary was here today for the ISRA race, and brought by his prototype for his upcoming dual tire cutter.

 

Unique features are dual, heavy duty, large 1 1/2" diameter grinding wheels, vertical feed and stop screws, and an A/C motor (no power supply needed)

 

It's designed so you can easily cut to different diameters, using economical stop screw set-ups that the user makes up to preset sizes, from an Allen head machine screw and lock nut.

 

Not sure if it is the A/C motor, the 150% larger grinding wheel(s), or hitting the perfect ratio and rotation speed of tire and grinding wheel, but this unit works better than any portable tire grinder I've ever used.

 

I trimmed down a pair of untrued Koford soft wonder and it worked superbly, quickly cutting two of them at a time, with no belt slippage and without any perceivable taper or difference in diameter. Shown below are those two tires.

 

The unit is definitely bigger than a Hudy, but definitely smaller than a Hudy and a power supply.

 

Differences in the production unit will be the main base (only) will be made from Corian and some sort of piece will be on top to facilitate trimming the tire width.

 

It will be available to raceways through Chicagoland Raceway, at the normal Backtrack discount.

 

Price isn't set in stone, but think $250ish.

 

Retail is officially $300-see post #43.

 

Please PM me if seriously interested, so Geary and I can gauge interest.

Mike,

 

Is the spacing on the axle wide enough to accommodate your fronts?

Yes.
 
Note, my last two versions are narrower than the original.
 
But while I don't have the truer in my possession, I'm 98% sure it'll even work with those.

I'm in the market for a tire truer but since I work in 1/32 my tires are mostly under 13 mm wide and between 18mm and 22mm in diameter. What advantage if any would this truer have for me over a Hudy besides not needing its own power source? Won't I be able to do two tires at once already?

 

Serious response only I really plan on buying a truer in the next few weeks but will hold of for this if it makes sense.

While the drum on the Hudy might be wide enough for two 1/32 tires, I don't think the axle stub would be.

Yeah I was thinking the same. But wasn't there somebody that was having a custom axle stub made up?

 

BTW if you go ahead with this what sort of timeline are you looking at?

There has easily been enough interest for Geary to proceed.

 

He is looking at 2-3 weeks.

 

I'll get a firm price posted ASAP.

I was able to see the truer in operation and it is a very nicely made piece.

 

Another feature Geary pointed out to me that Mike didn't mention is the truer uses standard size drum sanders that are available in different grit levels. A feature that all of us that mount our own rubber can appreciate when making that 1st cut down from raw donut to usable tire size. Just pop on the fast cutting, coarse grit and zip through those 20 sets of freshly mounted rubber. Should easily reduce the time in half, and you are doing 2 tires at once. For me, that is always the worst part of mounting my own rubber. 

 

Now if only Geary could come up with a way to automatically radius the tire edges.

 

Please place me on the waiting list of the 1st batch!

Kevin,

Thanks for pointing out that it uses standard 1.5" dia sanding bands you can easily get at Home Depot or Menard's.

 

I guess I didn't think of that, since my tire grinder, a 1990's circa Lee Robert's, also uses standard sanding bands, albeit 1" dia.

 

Geary did mention he will make replacement mandrel/drums available for those who want to be able to quickly set screw on ones with heavier grit  vs.

having to slide the "bands" off and on.

 

I have a feeling guys who mount their own rubber a lot will just have one drum with a heavy grit band , and one with a finer one, and just cut

one tire at a time.

 

IMO, the large 1 1/2" dia. drums and the A/C motor are superior features vs. cutting 2 tires at once.

Two tires at a time is a welcome feature for me. Would be even better if there was some device that allowed the wheels to stay on the axle when dealing with ... ahem plastic wheels.

I think Dennis is referring to press-on wheels.
