Slotblog member Brian McPherson reminded me that Ron Hershman had posted a small tire mounting tutorial back in October, 2007. With Ron's help, we located the thread and I'm going to repost Ron's less-detailed how-to here, just because it has a couple of tips that aren't included in Jay's tutorial above.

Mounting tires 101... ring the bell... class is now in session.

DO NOT USE CA GLUE to hold donuts on wheels. They will come apart.

1) Clean old wheels of old glue. Soaking them in lacquer thinner will do the trick.

2) Clean wheels, both new and used in acetone... this gets rid of any oils from thinner, old glue, or newly-machined hubs.

3) Use 3M Weatherstrip Adhesive... the yellow snot stuff. The best trick is to squeeze some into a class jar then add 25 to 35% lacquer thinner and mix. This stops the "stringing" of the glue when putting on wheels or donuts. This also thins it so the donut will absorb the glue into the pores. Better adhesion.

4) Get some pipe cleaners... fuzzy stuff on a piece of piano wire... you know what I am talking about. Craft stores sell them and they are longer and thicker. Bend the fuzzy stick in half and in half again. Now you have a real nice thick swab. Dip this into the glue and then slide in and out of the hole in the donut getting the glue to fully coat the inside of the donut hole.

5) BIG STEP HERE... put donuts on a sheet of WAX PAPER and let the glue dry. The donuts and glue will not stick to the wax paper. They will stick to your workbench if not using wax paper.

6) Coat the out side of the rim/wheel with glue mix. Stand on end with the set screw up in the air. Again set onto wax paper and let dry.

7) After a hour or two of the donuts and wheels drying, you are ready to insert wheel into donut. Get a small container and fill with some lacquer thinner. The quickest way is to dip the donut into the thinner and let it sit for about five seconds or so then quickly slide wheel into donut. Leave set on wax paper and dry.

8. Another big step... let assembled tires set for at least 24 hours before grinding/truing to size.

You can have lots of fun and possibly get quite a buzz making tires.

Maybe we can get Rick to make some tools like the AB SlotSport Donut Wizzard? Always wanted one, just too much of a pain in the butt to get just one item for the UK.

SLOT CAR TIRE MOUNTING PROCEDURE
...
Final note: I know this sounds like a lot but it's not so bad after you've done it a time or two. I like to do twenty or more pairs at a time and get it all over with at one time.

Wow, this looks like a "Federal project"... no, no, no way too complicated... just do what Ron says, use that glue and dilute 50/50... where are you guys getting ideas like this?!?!?!

[Hworth08]

... where are you guys getting ideas like this?!?!?!

Lee Gilbert recommends the spray glue as it's already thinned making the job quick.

Is it not alright to use Lee's ideas?

[Jay Guard]

George:

Sorry to overcomplicate the procedure but I thought it may be of some help to racers less experienced than yourself. However I've revised it just for you...

1. Glue rubber donut on wheel.

2. Finished.

Happy now?

You guys have spoken many times on this thread about thinning the 3M yellow adhesive with lacquer thinner. Well one small footnote on that. I used the fast drying 3M 8001 in the tube and all I got was a large lump of yellow snot. It didn't thin out at all. I've had the adhesive sitting around for about 7 months but it was never opened. When I did decide to use it I noticed two distinct colors of goo coming out of the tube, one was yellow and the other was amber. I think the glue seperated in the tube. Even mixing them together in a glass jar still didn't cure the problem. I ended up using the glue straight out of the tube after I mixed the two parts together. It dried super fast and I got the donuts on the hubs but not sure if it will hold.

[James Wendel]

Thinning the glue: I had the same problem with the "lump of yellow snot" until I started using Methyl ethyl ketone as a solvent. It works great. USE WITH ADEQUATE VENTILATION !!!

Jay's last point is important, especially when re-using old wheels: check the wheels for "true" before you start. (That really should have been Jay's first point).

In an earlier discussion, someone suggested slipping the wheels onto a length of axle-sized piano wire for gluing. A GREAT idea !!! The gluing of a dozen pair of wheels takes a matter of seconds, and you get zero glue on the set-screw bosses. A disposable foam brush does the trick. I buy them at the dollar store: 10 for a buck.

Has anyone tried using Permatex "Headliner and Carpet Adhesive"? It comes in a spray can and it's available at Automotive Parts stores. I've had good luck with it so far even on GTP and Retro cars (Wonder rubber). I just spray it into a plastic epoxy mixing cup and then apply to the rims and tires. Wait about 15 minutes and assemble with a JK tire mounting tool. No thinning required.

[John C Martin]

No but I'm sure it works great..I to use spray adhesive ( 3m, super 77)works good you can true the tires the next day...Lowes has it..

[Wayne Thomas]

can e6000 be used

[JerseyJohn]

can e6000 be used

I wouldnt Wayne. I had problems with it. I put the rims on a rod and use super 77 and spray them. On the tires I use

[Wayne Thomas]

can i use weldwood contact cement

[Michael Rigsby]

3M 8001 Super Weatherstrip Adhesive (yellow).

 

Read above post.  This is the correct glue to use.  Weldwood is not the same as  it used to be.  3M Superweatherstrip adhesive can be bought as most automotive stores and ACE hardware.

[JerseyJohn]

Wayne IMO i have been using weldwood for years with no issues. It holds firm and doesn't desolve from cleaning the rubber with naptha.Everyone has there own system....I like the weldwood.

[crazyphysicsteacher]

I have tried the 3M spray, gorilla snot and the weldwood. I have had tires peel loose when using the weldwood, it is very sensitive to wait time between application and putting the parts together. The trim adhesive 3M 80 is easiest to use, just spray on the rims then spray on a pipe cleaner to spread it inside the tire.  Then just follow Jay's steps to connect the two.  the gorilla snot needs to be thinned with lacquer thinner as it s too thick out of the tube to spread thinly and evenly. 

[Phil Hackett]

The best glue is industrial use only and 3M makes it. It's now $45/quart.

[John C Martin]

I just spray the 3 m in the cap, Then spread with a stiff little brush on the wheel and inside doughnut then push it over the JK. Doughnut spreader..Done.

[Martin]

I have been trying to buy 3M # 80. but no store has it in North Ca. We are saving the planet you know. E stores will not ship to me either, I have tried.

 

So whats the next best product. Thanks in advance for your help.

Thanks Jeff.

Before I order it and then they tell me it cannot be sold in my area I have this stuff in stock. Will this work?

 

A friend offered to buy and ship, but what a pain.

I tried the #77, no bueno. I can't believe Amazon won't sell you #80

[Mark Wampler]

I see this very old thread has popped up again.   Several racers who posted are no longer with us.  I will contradict posts #13 and #19.  I've been using Weldwood for the past 10 years and have no failures.  I'm on my 4th or 5th can.  I've mounted 100's of pairs! 

I use it straight out of the can.  NO Thinning.  Make sure the cement  fully set up and cured ready to mount.  You only have a couple seconds from the time the doughnut is dipped and mounted correctly.  Its a one shot process in mounting.   Once its fixed, its fixed.  Best to let dry for 48 hours, but sometimes I'll shape and rough in after 24 hours and then follow up the next day to around .825 for Retro cars.

[Alan Dodson]

I agree with Mark. I haven't used anything but Weldwood straight out of the jar and never had a problem with it. I don't do many metal wheels, mostly plastic, but I haven't experienced any failures with either type. i put a bunch of wheels on a piece of 3/32" piano wire, and bruch the glue on, then use a pipe cleaner doubled over to glue the inside of the tire. Of course the JK donut tool is a must!

[Mark Wampler]

 Of course the JK donut tool is a must!

 

Alan, I can't tell you the amount of tires I messed up until I got the JK doughnut tool !!
