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.

Geary was at both Chicagoland Speedway and Chicagoland Raceway, today.

 

Chicagoland Speedway, to ride and drive in an open wheel style car.

 

Chicagoland Raceway, to drop by a couple of the "2 True", production tire truers.

 

They came out terrific.

 

Some pics and updated info will follow.

It certainly did come out looking terrific Mike :)

Has a look of real sturdy build quality ,very nice alternative to a hudy. If I was in the market for a tire truer would definitely look closely at this one.

Ultra-heavy duty 3/8" drum shaft, along with the 1 1/2" large dia., truing drum, both firsts, for a

commercially available slot car tire truer. (AFAIK :) )

Despite the ultra-heavy duty 3/8" shaft and bushings, easy access, oiling holes.

..... the allen screw adjustment on the right, to dial in the same diameters

for both sides of the machine, in the process, creating virtually zero taper.

 

The truing carriage is pulled against that adjustment set screw by one of the pulleys.

Quality knurled brass feed screw.

 

Beefy, vertical stop arrangement allows easy installation and removal

of  Allen bolt/lock assemblies for preset diameters.

 

Want to cut a bit oversize?

 

Just lay a shim on top of the horizontal section of the truing carriage, beneath the tip of the bolt.

 

Also, that large area to the left of the brass feed screw works well to "paddle" manually, with your left thumb or fore finger.

 

IE- to quickly true up an old pr. of tires to the largest diameter possible.

 

"Disable"/remove the stop screw.

 

1) feed the smaller appearing tire until you get a "solid" grind.

 

2) leave the brass feed screw alone, it becoming your hard stop.

 

3) paddle the tire away from the grinding wheel and switch off the machine.

 

4) install the the other tire.

 

5) paddle the tire away from grinding wheel and turn on the machine.

 

6) paddle the tire into the grinding wheel slowly, eventually letting it up against the brass feed screw.

Pictured is the "2 True" next to an old  Lee Roberts/Wrightway truer.

 

Excluding the A/C power cord hanging off the base to the left, the 2 True is: 

5.5" deep

5.5" wide at the back , by the motor

4" wide at the front

3.25" tall

 

2 lbs, 8 oz.

 

The Wrightway is 1 lb., 5 oz.

 

Of course, keep in mind, you can leave your power supply at home when using the A/C motor

powered, 2 True.

The 2 True will come "stock" with two fine grit drums.

 

A N/C option will be to mix drum coarseness, or for guys only using it to rough tires,

have two coarse drums.

 

I used the original prototype 2 True with two coarse drums, and it cut like butter, but left fine grooves in the rubber.

 

IMO, a practical way to go for guys who make their own tires, is to have a coarse drum on the left, and a fine drum on the right.

 

You could cut oversize, using the method I mentioned before in post #39, putting a shim temporarily in place under the dia. stop screw,

rough cut on the left size , move the tire to the right size, remove the shim, and cut to preset (final) dia. that corresponds to your screw combo.

The unit comes set up for 3/32" tires.

 

It uses a stepped down 1/8" axle that rides in 1/8" bushings.

 

The 2 True is adjusted , using 2 identical size jig wheels.

 

It should be real close each time, but like the Hudy, getting it perfect will be the responsibility of the purchaser.

 

The design of the adjustment system should make it as painless as economically possible.

 

Cutting 1/8" tires is a matter of switching to a 1/8" axle.

 

A possible option, I will run by Geary ASAP, will be an axle  that is stepped down to 3/32" only on one side,

so you can cut either size tire, without changing axles, albeit, only one at a time.

 

The price is now officially $300 retail.

 

Higher than the original rough estimate, partially because of higher parts costs than expected,

but mostly due to increasing the profit margin to raceways, to make it substantially more than

the pitiful one on Hudy tire truers.

 

These first two are going out to the first guys who ordered them.

 

I have quite a long list of guys who expressed interest/ordered them.

 

Please contact me to confirm if you still want them, and if you have any special drum or axle requests.

Geary confirmed that he would be happy to do a 3/32"/1/8", combo axle, and if ordered ahead of time, would be no additional charge.

 

Spares axles of both types will be available, along with spare drums.

 

Price TBD.

 

 

Wow, what a nice piece of workmanship.  Top notch!

I'm sure Geary will appreciate the kind words.

I got a good question late, last night, asking some info I meant to provide, but forgot.

 

The capacity of the machine.

 

As is, it will go from smaller than you'll ever need for Eurosport, .580"-, to about 1.360".

 

On the slight chance you would need smaller (for some sort of small dia. front wheel ??), you would install a smaller O ring,

to pull the truing carriage in closer.

 

You might need a longer bolt for your stop.

 

For larger, you could get 1.5" + by removing material from the top of the base, under the truing carriage.

I couldn't quote an RPM, but it's on the slower side, which is easier to get away with,

with the large dia. drums.

 

You certainly aren't getting any over expansion, like you do when you zing up a Hudy.

 

I should of posted a video of grinding a tire while I had a prototype in my possession.

 

I can still fire up the production model I didn't ship today, waiting for some further info from the customer,

to possibly give you an idea.
