If you get a credit card at Jumbo Encho, and there is no sign-up or annual charge for this, there are some other services you get for free also, even if you never use the card. There are workshops in the stores that you can use that have a variety of shop tools for both wood and metal. There is also someone in the workshop who can cut large pieces of wood for you. From the service desk, there are 15 power tools (at my local store, anyway) that you can borrow for 1, 2 or 3 nights for use at home.
If you don’t have an Encho card, these tools are also available for rental, but maybe for a shorter time period. And at my local store, if you buy the materials at the store, one day a week the helpers in the workshop will cut the wood for free to your specifications.
