for Ishkur is in the mail, scheduled to arrive Friday.
I went out to Do It Best this morning with a few inches of the PVC and the 2 sets of inserts that didn't work. Jason (who I talked to on the phone yesterday) opened up a pack of 3/4" and they were the right ones. If anyone can't find caster inserts at your local stores, see if there is a Do It Best around, or they are $1.79 on doitbest.com.
I showed him my Lowes receipt that said the PVC was 1/2" and he said, "I bet you got thin wall." He took me over to their PVC, CharlottePipe just like what I bought. We compared the inside of mine to the inside of theirs and theirs was thicker. He said the 1/2" inserts might have fit the regular kind. I didn't even know different walls existed, I just bought the kind on the end of the display that said 1/2" and didn't look at any details on the tag, if there were any.
When I got home and put them in the short pieces of PVC and pushed them into the tees, they stuck out the end of the fitting about 3/16". I don't know if it's something I did, or because the Lasco fittings are different than the inventor used, or both. On the video he says, "Push down firmly, these are very hard to get in but they do fit in." I leaned all my weight on it and they were in as far as I could get them, so I just had to leave it.
In the box I included one of those tools to take the PVC apart if needed. I can't imagine why you would need to, but you should definitely have the removal tool just in case. It is in a sack along with some homemade cat toys that will be under your fridge in about an hour.
I may run back over to W-M today and get some more of that fabric so I don't have to worry they will sell out before we find out how her saddle fits.
