I've noticed on 2 of the new cars that come straight out of the BSA's stock box that they do not fit into the axle boring jig I have. I have one block that came from an older box and it fits fine. Has anyone else noticed an increase in width of the block? Looking at the grain in the wood, it would seem that that the older block has a more dense grain (that may not be the correct way to identify this).

This is my first post on the site. I would like to say thank you to those who have offered up their 'professional' advice on PWD racing. For a dad who gets all pumped up once a year for this event, your comments are true gold. Although, you can make a guys head spin with the amount of information given.

Thanks again.

You will find sometimes the block needs to be sanded down to fit your jig and sometimes you might need to add a small spacer to make the block fit more securely in your jig. Shouldn't have to sand much or add much of a spacer. Just make sure it's a tight fit. I had five blocks to drill last night and found one needed a thin layer of paper spacers to fit securely in my Goat Boy drill jig. Hope this helps.

I would recommend, when sanding the block down, that you sand the block on a flat surface such as a marble countertop, plate of glass, steel bench top or a good flat wooden bench, in that preferable order. Lay your sheet of sandpaper down on one of these surfaces just mentioned, a sticky backed sandpaper sheet works best. This will assure a good even sanding. Use light to moderate pressure when applying downward force to the block. It's real easy to take a block out-of-square.
