Description of the product.
This D-shaped backing plate for flat platten assembly has an even deeper reach than the previous one, making it ideal for slack belt grinding. This plate is precision CNC cut from 3/8 inch thick aluminum “steel that has been hot rolle.
In order to ensure that axles are parallel to the plate, 1/2-13 precision taping is used to create wheel mounting holes.
The hole in the center is 1/2″ in diameter, the slots for a flat platten mounting bracket are 1/4″ wide and 6″ apart, and the u-shaped adjusting slot is 3/8″ in diameter and accepts a 3/8” bolt or stud.
The axle holes are 10.5 inches in diameter “a distance measured from center to center.
It is simple to mount an 8″ long by 2-1/2″ diameter wheel on this backing plate if you use two 2” diameter wheels “A large grinding surface is achieved by using a wide flat platten between the wheels. The rectangular spacer plate has a thickness of 1/8 inch “This effectively makes this plate 1/2″ thick through the pivot point, allowing it to be interchanged with any 1/2″ thick d-plate on the market.
We include two grade 8 bolts, each measuring 3,5″ in length and with a 1/2-13 thread, as well as four nylon spacers, two 1/2” washers, and two half-nyloc nuts. Tracking wheels and a platen mounting bracket are also available in a separate listing for an additional cost. Also available in half-size “Aluminum is a type of metal.
The D-backing plate is thick and sturdy, and it cuts cleanly and precisely. The bolts, on the other hand, are not 1/2 – 13 and are not threaded all the way through. The bolts appear to be 1/2 inch in diameter, but the thread count is 17 instead of 13 or 20, which correspond to coarse and fine threads, respectively. Even with the spacers, the bolts’ bottoming out results in more than 5/16 of lateral play. Because the holes are not threaded for 1/2 – 13 bolts, I am unable to use my own 1/2 – 13 bolts. There is no way I can thread the holes again because their size is too close to the threading I require. Due to the fact that they are grade 8, the threads on the bolts can’t be cut any further, and the uncut bolt shaft is too thick. I’m also not sure if the bolts are standard or metric, or what die was used to cut these bolts.
Buyers should exercise caution. Due to inconsistencies in the bolt size and thread count, I have been left with something that I may not be able to use.
