The tank is aluminum, surprisingly easy to cut on a table saw. I traded a box of steaks to have it TIG welded. The frame is MIG welded, mostly by me but with the assistance of a buddy who just took a welding course. The frame shape is taken directly from pictures of 100 year old Indian board track racers.
Yes the top tube is almost parallel to the ground. Just a bit of slope up toward the front. The front fork is a Monark springer of a heavier design recommended for motorized bikes.
I drew out the shape on the board you see pictured and calculated the head angle carefully before bracing the the head tube in place. I added a bit of extra trail so hopefully I err on the side of increased stability.
Husky is a maker of of heavy duty bikes and parts similar to Worksman but with easier online purchasing. Very economical prices.
