On VFR departure from LAL; climbed to 1;500 feet. Was just within the 5 mile ring around LAL's class D. Single-engine aircraft crossed from left to right approximately 100 feet above and 200 feet ahead of my plane. I was in contact with the LAL Tower; but they were very busy and had a full frequency. As my plane was just about to exit the class D; the other aircraft was probably just outside of the 5 mile ring. My ADS-B had been removed for service and I was ferrying the plane to ZZZ; a distance of 14 nm; without ADS-B in.
GA pilot reported an NMAC during climbout from LAL airport.
