1. ## Dimension Check

As I was finishing with the glue up of the inner skins I started looking at the next step which is the flanges. The dimension given for front flange 3 is 26 3/16". However when I look at the layout of the pieces shown in the exploded view and my base construction it appears that this piece will fit between the two notches in the front of the top skin. This dimension is 25 5/16". Am I missing something?

Similarly I can't see any rationale for the overall width of the rear flange plate being 30". To me it should be 1/4"+29 11/16"+3/4" = 30 11/16". I need to look at this a bit further as I have already cut this piece to 30" and it may be too short.

Perhaps I am nit picking with these questions but I am just trying to understand things better and make note of possible errors to improve the overall plans for future users.

Thanks, Dave

2. I think I ran into some problems too but then I used little different thickness of wood and remember that 3/4" isn't always 3/4" it can be litlle thinner. As I was building i was measuring the base it self and the commparing with the plans, if something did not match I just made it so it worked witht he base. And after I was finished with building the whole machine I was surprised thatall of the stuff was leveled witout even using level ...

3. The front flange doesn't go in between inner skins, you have to add extra material for the other vertical flanges so it would be 25 5/16 + 3/4 +/- + 3/4 +/- which is about 26.8125 which is acutally correct in the plans...

Note: Vertical front flanges are flush with inner skins not in between....look at the finished machine...

4. fast,

Thanks for the clarification on the location of the flange #3 piece relative to the vertical flanges - that makes sense now and when I take I closer look at the exploded drawing I see how it comes together.

Like you I too have been measuring off the base when marking out subsequent pieces for cutting. For some reason I didn't do this with the rear flange plate and it appears I have cut it too short. I will look for ways to adapt this or cut a second piece if need be.

v1.0 of the plans had an incorrect dimension for the rear flange, mine was also an inch shorter then what it should have been. Luckily it is a wood base and not metal so easy fix.

• V 1.2 has the overall width of the rear flange plate at 30". I need to take another look at this but it seems to be a tad short. Probably an easy mod if required or even cutting a second one not the worst thing.

• Dave,

I'm out of town until after the weekend and can double check dimensions for you then. In the meanwhile, maybe this info will help:

The vertical flange segments don't actually align with anything. For example, if you look at the middle right photo on page 115 you can see that it sits back from the face of the inner skin by a small distance. I intentionally left this reveal, since it can be difficult to have the finish look nice on two co-planar surfaces that butt together. In practice, you can change the location of the flanges to wherever you want. As long as the front plastic will cover it, all should be good. Nothing here is terribly crucial.

The rear flange plate needs to be narrower than the base of the machine. The sides of the cover plastic sit to the outside of this, and then they rest on top of the base. So if the rear flange plate is as wide as the the base then the plastic will be too far to the outside of the base to rest on it.

• Bob,

Thanks for checking in while you are on the road. No worries about this as the other responses and a more careful study of the plans and photos have helped me get my head around the front flanges. Also I had a few minutes tonight to look at the back flanges and I think it is sinking in.

This weekend's goal is to get the front flanges on and then fill holes, sand and paint.

Thanks again, Dave
