There are really three steps to becoming a member of  HAREI:

You are welcome to join a few meetings and raisers before becoming a dues paying member, but we will check that dues are up to date before you can participate in one of the design workshops, submit a BOM for bid, have a mentor assigned or borrow any tools. 

Dues and donations are always appreciated.

Online Payments

You can pay your annual HAREI membership dues, or separately buy a HAREI t-shirt securely using PayPal (if you do not have a PayPal account, you can also use this to charge your payment directly to a credit card). See the About page for details on the donation amounts.

For t-shirt orders please fill out the styles and sizes using this form. Please pay for the T-shirt first (not included with annual dues).

If renting the ladder lift - please watch the Ladder Lift Assembly and Operation Video.


You can also make a contribution of any amount to help HAREI. We use all funds to support our administrative expenses (such as this web site) and to purchase tools that members can borrow for their projects.
