You know what would be nice?

A good, heavy duty wheel with bearing races shaped to accept a high quality, sealed bearing.

Those cage bearings are kinda delicate.

Also, maybe when I get some tacky grease I'll try just lining that race with balls and leave the cage out of it. Of course, I'll probably just get into trouble. But I'm fairly adventurous. Maybe I'll give it a try.

you do have the dust cap over that bearing don't you (sprocket hole nees to be enlarged for it to fit

I have many coaster brake wheels here that overheated when using a brake designed for 11mph at 35mph - several have small cracks in the bearing race nearest the pads - one had the hub so heated that it expanded, then broke loose the spoke ring when it cooled

when a customer comes in with a coaster & no dust cap, I make a plastic one , grease the bearing, adjust the bearing with a bit of play to leave room for heating, and pack the plastic cover on to hold the grease - this needs to be changed every so often when the plastic wears

......................just a slight amoun5 of play in the bearing is better than a bearing of that type that is to tight." --Mapbike.

Everybody was saying NO PLAY at all. And I think a little, (VERY VERY, LITTLE) play is best. And I mean so little play that you could almost say, NO PLAY. Even a little bit too tight on those bearings will destroy them quickly.

Now I'll go back and read the rest of the thread.

ok guys on coaster brakes is it better to cut the arm off and grind it round and add cantilever brakes or should you just remove the arm completely? im getting a set of rims and am afraid to use them because of the horror stories about them burning up or plain don't work at all

In my experience... and this was a Long time ago since I've run anything with a coaster brake, is to leave the arm connected to something or it'll move if the brake is applied causing it to throw out the bearing adjustment as well as burn up the brake pawls etc... I'd say either use the coaster brake as it's meant to be there or swap out the rear rim in favor of a freewheel type... but like I said, it's been over 30 years since I've had anything with a coaster brake on it...

My progress today was on the Stingray frame stripping off all the paint close to the end of the day at the shop since today was a little slow, but paced just enough that I couldn't mess with either bike without a customer showing up for something.

To strip the frame I still rely on the old tried and true Aircraft Paint remover spray.. just spray it on, wait about 5 minutes and hose off the paint as it blisters off. I got about 95% of the paint off the frame today just using the paint stripper and hosing it off... But while at the shop after my wife got there she was asking me if I needed anything from Harbor freight after seeing this month's coupons... I needed an engine stand but got one before the new coupons got here so I saw they have their big blasting cabinet on sale this month for $179 instead of $299 so I picked one up on the way home tonight as well as a 40lb box of garnet blast media. I'l be able to assemble it in the morning before I have to open up shop and get it up and running so hopefully I'll have time to blast off the chrome from the crank set, the front sprocket, and the fork legs to get them prepped and ready for powder coating.
I'm not going to powder coat the frame or fork legs, but ALL the small p[arts will get powder coated either black or lime green, then after everything is clean, chrome free, rust free, and painted I'l do some airbrushing to the frame and tank. I don't want to go graphics crazy or overload it with airbrushing, but a few little touches here and there can really change the way the bike will look. My plan for the airbrushing is to do some green true fire in key areas and keep the rest of the bike solid... well... maybe a litle pinstriping, but I'll decide more on that when the time comes, it's real easy to overload something like a bike frame or tank with too many grapics so I'll decide how I want it to look when I get closer to ready to paint everything.

For the mountainbike... No progress today... just not enough time, and I still need to make time to go to the welding supply shop and get my argon refilled... it really drives me nuts everytime I get ready to do something on that bike and realize I need to weld things back up first...
