it is my understanding that Steve outsources much of the rpoduction for items and he has to order in bulk to make it feasible. A lot of times , he may decide not to place his own order because how slowly a product moved or sat on the shelf or he didnt like previous quality of a product or .. feels there isnt enough demand. For instance he had a lot of ... woodrail legs manufactured and last i heard he was down to about 40 but he might not again ... make an order as they didnt sell as quickly as he thought. i cant say the reasons for the lockdown bars themselves but he hasnt had them for sale for a few years now i think.
