Connect a DeWalt DW735 planer port to a 1-1/4 in shop-vac hose
How to join a DeWalt DW735 planer port to a 1-1/4 in shop-vac hose, and what stops it leaking dust.
Not compatible without stepping down. A 1-1/4 in shop-vac hose is far larger than the DeWalt DW735 planer port, so it needs a 2-7/16 in to 1-1/4 in step reducer.

The two ends
| End A | DeWalt DW735 planer port (2-7/16 in OD, 62 mm OD) |
|---|---|
| End B | 1-1/4 in shop-vac hose (approx 1-1/2 cuff in OD, 1-1/4 in ID) |
| Fit type | male port into hose cuff |
| Reducer needed | 2-7/16 in to 1-1/4 in step reducer |
Shop notes
The hose is about 32 mm and the port about 62 mm, a gap of 30 mm, so the port simply swallows the hose with no contact. A 2-7/16 in to 1-1/4 in step reducer is needed, and even reduced the airflow is mismatched between the DeWalt DW735 planer port and the 1-1/4 in shop-vac hose.
Wrapping tape to close a 30 mm gap never seals cleanly and chokes the airflow further. Step the sizes properly, or pair each end with a fitting closer to its own size.
