2009 at the Hammond Barn

The design record lists two types of 16" rim. One is listed for 9.25x16 (HUP)tires, the other for 9.00x16 and 10.50x16.
Both are DND designs (not K-H), and are listed as having 6 inch width and 10.827 inch mounting bolt circle. (They could be K-H made and DND designed)
The one for 9.25x16 tires weighs 46 pounds per wheel, has a 5 degree rim taper, 1-1/8 inch flange height and 0.5625 inch centerline offset.
The other type for all other CMPs weighs 67 pounds per wheel, has a 1-1/2 degree rim taper, 1-1/2 inch flange height and 0.250 inch centerline offset.
The weight difference seems to be mainly because the HUP rims are made from thinner stock. It is probably possible to mix HUP and "other" CMP wheel halves and have a driveable wheel, but due to the different geometyr of the rim and the different offset I don't hink I want to make the experiment to prove it works or otherwise. My first explanation for the different offset was that the tires were the early equivalent of "wide profile", then i thought again (10.5 is wider than 9.25) (even stranger, the 9.00 cross-country tires had a wider section than the 9.25 ones - I don't understand).

Comments on Bob's theory - anything could be possible on a one-off prototype basis, but would they create a die to mark a one-off rim? Most HUP rims are 5 degree taper, not 0, that's why I think their tires are less evil to remove from the rim.
The only rims listed as Dunlop designed (as opposed to manufactured) are in the 5.00x18 size for 7.00x18 tires which had comparatively narrow .75 inch flange width, 3 degree rim taper and a bolt circle different than all CMPs but closest to the C8's rims for the 9x13 tire.

They were stamped by hand.... the RF is not even


DUNLOP looks like one stamp the 0 is not lined up and the HA 900 was stamped individually....... my conclusion is one of a kind or very low production.....

The question on my mind is when did they start making 6 bolt rims.... for the HUP or did they exist for earlier C8.....? or are all C8 13 inch rims???

The Prototype rims in question are definitely of lighter gauge steel than any other HUP wheel that Rob has worked on......

Curious!!!!!

Bob,

The Ford Lynx takes the same 6 bolt 16" rim as the C8A Heavy Utility.

Hi Brian

When did the Lynx came into production.....??? The rims Rob took off the Prototype were exceptionaly light weight and flimsy.... I know they were rusted but when we worked on them the center flat section was really flexing like sheet metal........ Surely the Lynx must have been using a thick walled rim in view of the extra weight it carried.

Strange.

After the antique gold discovery in ENgland I bet ROb will be taking the doors skins apart to see if any treasures can't be found.

It looks like the weather for the last weekend in September was going to be the shits. Rain and more rain. Reminded me of May-Mid August... Bob and Grant where busy elsewhere, so I had the barn to myself (not including the mosquitoes).

The rim was sandblasted in Bob's blasting cabinet this morning. Nothing new was revealed. I will upload my Blackberry pictures later. A few things were noticed tho': a. the stamping was on the inside half of the split rim. b. the Dunlop stamp was indeed two stampings overlapped. Either a nervous operator or s/he had too many beer at lunch.

The rest of the day was spent cutting the tires from the HUW's front rims and removing the instrument cluster (which is in rough condition). The data plates are in great condition. The rest of the HUW will make its way into Bob's back field for the winter.

After a morning of working in the rain, I called it an early day and headed back to complete some domestic chores...gotta keep on the wife's good side!

What do two unemployed bums do in Ottawa on a Friday? Sandblast at the barn! Bob and I decided to take advantage of the "good" weather on Friday to do some work at the barn. Time was of the essence as we also had a Gracie's call that night.

First order of the day was to remove Bob's truck Lettie, from the barn. It took a few trys to get her rolling and the idle sorted out, but she finally rolled out under her own power.

She was running a tad rich:


Bob then blasted a good number of sheet metal panels from his and some donor cab 11s.


We set up a containment "cathedral" and recovered about five bags worth of media of the ten we used. This recovered quartz will be screened twice and pushed through a larger nozzle. It will save some money and we saved a lot of time by having the containment shelter - we just rolled up the tarps and refilled the bags with the sand that landed on the tarps.

I took advantage of the situation to clean up some rims. The aim was to knock off the big deposits of rust etc... in prep for treatment, priming and painting (next week).


Interestingly, we discovered other stampings on the Dunlop rim - Bob will post photos later (his camera has better resolution than my camera).

I was sitting around the house stumped with jack to do... So, off to the barn I went. Space around the barn is getting crowded due to the recent influx of CMPs. Winter is on its way, so snow lanes will be needed for Bob to move the mountains of the white stuff that surely will bless us with its presence.

Bob and I decided that the best place to put the Prototype "on ice" was next to the barn adjacent to "Ted's truck". It will be out of the way but easily accessible for the many small over-the-winter projects.

The first step was to remove four stumps. Since Bob was at work with his new job, the tractor was not available to dig them up and haul them out of the ground. With no HE around, all that was left was muscle power. It was a good time to burn off some of the fat I put on while working for the government. Armed with an axe, shovel, pick and come-along, I managed to dig out three of the four on Thursday morning. The fourth and smallest stump can wait until later – sadly, I need to get back into good shape…

The digging took the most time, but once I got a chain around the bottom of the stump, the come-along and farmers jack made easy work of the removal. I can only imagine the effort it took for the pioneers in this country to remove the thousands of stumps to clear the land.





A couple of loads of fill will even out the pad and then we can move the Prototype and shelter.
