Title: 1/2a proto wheels
Post by: Jim Roselle on November 16, 2013, 06:08:37 PM
Does anyone know of a source for the disc type wheels used on 1/2a proto planes?

Thank you,
Jim

Speaking of "Proto," what does that mean? I know it's something specific about 1/2A speed. Is that the class of what we're building for our contest over at CEF?

Busted! CEF profile scale Reed speed is based on 1/2a proto. Rules are bottom of page 7 on this document:

These are the wheels I'm looking for. May go to a fabric store and see if there is a button I can modify.

If you mean these here is my last set from many years ago. Set up for a pan and a T.D. Norvel will work also. Let me know if interested

I'm actually looking for the super thin cast urethane ones but I may be interested in those. Pm me a price please.

I caught Jim last night, but only because I was looking around too. I thought I'd just PM a couple friends to keep it on the down low. ;D

Are those Veco thin wheels?

I get slightly annoyed with the lightweight foam wheels that are all one can get anymore. 

I am using wooden wheels from a baby ringmaster or similar, unless I can't balance then I have some foam on plastic light wheels to reduce nose weight.

If your referring to my post with the pictures of the wheels. They are not Veco rather they are Perfect brand wheels from the 50's and they are well formed to the hubs. aluminum gear are hand formed. Size of the wheels is about 1- 1/8 inch.

Could it be that you are referring to the Glen Lee wheels?  If so I will check in the shop.  The smallest I have are for AMA Scale Racing.

Well, historically, "Proto" speed events normally refer to those speed events that are timed from a standing start.  I may be wrong about this but I think the first AMA proto speed event was Class B Proto Speed.  This evolved from the Class B Team Race event that had a minimum wing area and cross sectional dimensions as well as a canopy with a realistic pilot and a cowled in engine.  B Proto had the same wing area and required some form of a canopy, two wheels and of course limited to .29 engines.  Timed from a standing start for 14 laps on 60 foot lines which is a mile.  About the time that event was dying, Dale Kirn came up with a 1/2A Proto speed event, cowled in engine, minimum wing span area, had to have a canopy, two wheels, timed from a standing start on 42 foot lines for 1/2 mile.  Tht event has evoled to some of the rules being changed.  Many of the current "official" (whatever they are now) proto speed events and some of the sport speed events, some unofficial, have a standing start for the timing.

Hope this answers your question.

Thanks, Trostle, that pretty much answers my question.

Jim,

I made mine from a 1" bar of acetal I had. Simply trued it up on the lathe drilled centre for the axle, and parted off about 1/8".

Too easy if you have a lathe, if not find a friend with one OR look on the NASS site's parts finder

Could it be that you are referring to the Glen Lee wheels?  If so I will check in the shop.  The smallest I have are for AMA Scale Racing.

Doc, I ordered some assorted sizes of Glen Lee wheels a few years back, in the 1.5"-2.5" diameters, in red, yellow, & black...
Excellent pieces, and very affordable.
 
1.)  Is Glen still making these? (and in 1" dia.?)

My last computer crash wiped out a long list of 'favorites', and I haven't been able to recover Mr. Lee's contact info.

Any idea where Dennis Lipsett got that aluminum bar stock for landing gear legs??? (is it #7075? Or #6061?)

I am also looking for Glen Lee's contact info to get some wheels.  Anyone help out here?

My work was in the aluminum industry so getting what I needed was not a problem. It is 2024 alloy if my memory is still working back that far
