Thank you guys...I appreciate it. I have a rather dumb question. On this OcCre model, I noticed many of the blocks had holes that were very tiny and not well formed....now I'm thinking I should have drilled them out a bit. Will I have problems down the road? Is this a common thing or a rookie mistake? I'm not sure how many of the blocks I will have to pass thread through, but I'm now realizing I should have thought ahead.......
